==MIDDLE EOCENE ABYSSAL BENTHIC FORAMINIFERA IN THE EASTERN EQUATORIAL PACIFIC==
 +

We report on the faunal transition of benthic foraminifera during the middle Eocene at Site U1333 (4862 m water depth, 3,560–3,720 m paleo-water depth) of Integrated Ocean Drilling Program Expedition 320 in the eastern equatorial Pacific Ocean. ...... Based on Q-mode cluster analysis, four sample clusters were recognized and their stratigraphic distributions were generally discriminated in the lower and upper parts of the study interval. Thus, there was only a small faunal transition in the abyssal eastern equatorial Pacific during the middle to late-middle Eocene. The faunal transition recognized in this study may be related to recovery processes following intense carbonate corrosiveness in the eastern equatorial Pacific during MECO.

==MOLECULAR EVIDENCE FOR LESSEPSIAN INVASION OF SORITIDS==
 +
 
 +
[[Image:PLoS_ONE.jpg‎‎|left|80px|]]<font size="2">
 +
The Mediterranean Sea is considered as one of the hotspots of marine bioinvasions, largely due to the influx of tropical species migrating through the Suez Canal, so-called Lessepsian migrants. Several cases of Lessepsian migration have been documented recently, however, little is known about the ecological characteristics of the migrating species and their aptitude to colonize the new areas. This study focused on Red Sea soritids, larger symbiont-bearing benthic foraminifera (LBF) that are indicative of tropical and subtropical environments and were recently found in the Israeli coast of the Eastern Mediterranean. We combined molecular phylogenetic analyses of soritids and their algal symbionts as well as network analysis of Sorites orbiculus Forskål to compare populations from the Gulf of Elat (northern Red Sea) and from a known hotspot in Shikmona (northern Israel) that consists of a single population of ''S. orbiculus''. ......

==FLEXIBILITY IN SYMBIOTIC PARTNERSHIPS ALONG A NATURAL TEMPERATURE GRADIENT==
 +
 
 +
[[Image:MEPS_front.jpg‎‎|left|80px|]]<font size="2">
 +
Benthic foraminifera of the family Soritinae are important members of coral reef communities, contributing to carbonate deposition on coral reefs. These giant protists form photo-symbiotic associations with microalgae of the genus ''Symbiodinium''. The extent of flexibility in foraminefera-Symbiodinium partnerships is not well understood. While some studies suggest foraminifera exhibit strong specificity with regard to symbiont choice, recent work illustrated that at least a few taxa are able to host >1 symbiont type. We explored the symbiont diversity of a widely distributed soritid foraminifera (''Marginopora vertebralis''), sampling 369 individuals from 16 populations distributed across a wide latitudinal gradient (31 to 9°S) in the western Pacific Ocean using the internal transcribed spacer region 2 (ITS2) of rDNA.  ......

==BENTHIC FORAMINIFERAL COMMUNITY CHANGES AND THEIR RELATIONSHIPS TO ENVIRONMENTAL DYNAMICS IN INTERTIDAL MUDDY SEDIMENTS==
 +
 
 +
[[Image:MEPS_front.jpg‎‎|left|80px|]]<font size="2">
 +
The temporal and vertical variability of live intertidal benthic foraminifera was studied in parallel to environmental variables such as porewater and overlying water nutrients, salinity, temperature, sedimentary pigments and organic carbon.  ...... multivariate regression analysis for the whole community assemblage showed that the significant community composition changes over time in the surface layer could be related to fluctuations of several environmental variables, mainly those related to sediment food availability. The macroalgal bloom that occurred during the winter months had no detectable effect on benthic foraminiferal abundance or community patterns. Overall, the intertidal foraminiferal community in the Bay of Cádiz showed a highly dynamic character and a clear vertical distribution which could be effectively captured by studying the uppermost sediment layer at sub-centimetric vertical resolution.

==FORAMINIFERA AND SEQUENCE STRATIGRAPHY OF MIOCENE ON THE EASTERN SIDE OF THE GULF OF SUEZ, EGYPT==
 +
 
 +
[[Image:NeuesJahrbuch_front.jpeg‎|left|80px|]]<font size="2">
 +
Stratigraphical studies of Miocene exposures on the eastern side of the Gulf of Suez (Wadi Gharandal, Wadi Baba and Wadi Feiran) reveals conspicuous vertical and lateral facies variations due to syngenetic tectonic activity related to rifting. Studied samples include 88 species of foraminifera (39 planktonics and 49 benthonics). Six planktonic biozones (M2-M7) were distinguished. The sequence statigraphical investigation of the Burdigalian to Serravallian succession reveals six third-order depositional sequences, bounded by physical unconformity surfaces reflecting phases of sub-aerial exposure, deposition of alluvial fans, polymictic conglomerates, evaporites and the presence of a faunal break, which could be correlated within and outside Egypt. These sequence boundaries are primarily related to regional tectonism associated with rifting or related to eustatic sea-level fluctuations.

This work presents a taxonomic, biostratigraphic and paleoecological study of planktic foraminifera recovered from the Aptian–Albian carbonate-dominated succession of Deep Sea Drilling Project (DSDP) Site 364, located in the Kwanza Basin (offshore Angola). Twenty-nine planktic foraminiferal species were identified, enabling the identification of late Aptian–late Albian biozones, from the ''Hedbergella trocoidea'' Zone to the ''Pseudothalmanninella ticinensis'' Zone.  ......

==ECOLOGICAL DISTRIBUTION OF RECENT DEEP-WATER FORAMINIFERA AROUND NEW ZEALAND==
 +
 
 +
[[Image:JFR_cover.gif‎|left|80px|]]<font size="2">
 +
Census counts (>63 μm) of 461 species in 361 samples are used as the basis for recognizing and mapping associations of deep-sea benthic foraminifera (50–5000-m depth) around New Zealand, southwest Pacific (28–60°S, 155°E–170°W). Fourteen faunal associations are identified by cluster analysis with five of these subdivided into 20 subassociations. ...... A major reason for this study was to understand the environmental drivers of foraminiferal faunal distribution in this region to assist in paleoenvironmental interpretations of fossil faunas which have a significant regional character. Canonical correspondence analysis indicates that the distribution of bathyal and abyssal associations is more strongly influenced by depth-related variables, while shallower associations are influenced by latitude-related differences in surface-water characteristics. ...... Environmental variables related to bottom-current strength appear to drive the faunal composition of three associations at shelf and bathyal depths. Cluster analysis enables the recognition of 22 anomalously deep faunas that are inferred to have a significant displaced content. There are no significant diversity trends correlated with depth, but species diversity decreases with increasing latitude at all depths.

==WEIGHT LOSS AND ELIMINATION OF PLANKTONIC FORAMINIFERAL TESTS IN A DISSOLUTION EXPERIMENT==

[[Image:JFR_cover.gif‎|left|80px|]]<font size="2">
 +
Their ubiquitous distribution and common occurrence in marine sediments make planktonic foraminiferal tests an ideal archive of past physical conditions of the upper oceans. However, their tests are prone to dissolution, especially in the deep sea. Their species-dependent removal from sediments is well-recorded, and is exhibited by the absence of some species after complete test disintegration, while others still remain. In order to further understand the dissolution process of planktonic foraminiferal calcite, we treated tests of ''Globorotalia cult rata'', ''Globigerinoides ruber'', and ''Neogloboquadrina dutertrei'' (315–355 μm intermediate diameter) with a weak buffered acetic acid. ......

==SYSTEMATIC TAXONOMY OF EARLY–MIDDLE MIOCENE PLANKTONIC FORAMINIFERA FROM THE EQUATORIAL PACIFIC OCEAN==

[[Image:JFR_cover.gif‎|left|80px|]]<font size="2">
 +
Integrated Ocean Drilling Program Expedition 320/321 at Site U1338 (equatorial Pacific Ocean) recovered lower–middle Miocene (17–13.5 Myr) sediments containing unusually well-preserved and diverse planktonic foraminifera. Previous taxonomic study of planktonic foraminifera from this interval in the eastern Pacific Ocean has been hindered by the absence of biogenic carbonate. Here we present a taxonomic analysis of these foraminifera, including wall textures and species variability, supported by scanning electron micrographs. Specimens exhibit open pore spaces, little evidence of calcitic overgrowth on the wall surface, and in many cases spines. Fifty-five species are recorded, including ''Dentoglobigerina juxtabinaiensis'' n. sp. Dominant genera include ''Paragloborotalia'' and ''Globigerinoides'' with common ''Dentoglobigerina''.

==FORAMINIFERAL RECORD OF SURFACE PRODUCTIVITY CHANGES DURING THE CONSTRICTION AND CLOSURE OF THE CENTRAL AMERICAN SEAWAY==
 +
 
 +
[[Image:JFR_cover.gif‎|left|80px|]]<font size="2">
 +
We investigated middle Miocene–Pleistocene deep-sea benthic foraminifera from IODP Hole U1338B in the eastern equatorial Pacific (EEP). Starting at ~12 Ma, periodic constriction and closure of the Central American Seaway and resulting productivity fluctuations led to distinct changes in benthic foraminiferal composition at 9.5, 5.6–5, 4.5, and 2.1 Ma in the EEP. A temporal increase in high-productivity taxa, known as the late Miocene–early Pliocene “biogenic bloom,” produced a high organic flux to the seafloor from 6.4–5.4 Myr. Our results suggest that, while overall productivity increased at that time, seasonal inputs of phytodetritus did not until after 4.5 Ma, when upwelling, recognized by an abrupt rise in ''Epistominella exigua'', increased during another constriction of the Central American Seaway, marking the beginning of modern oceanographic conditions in the EEP. Although foraminiferal diversity increased during the late Miocene–early Pliocene biogenic bloom, it was not enhanced by the high phytodetrital input from 4.5–3 Myr.

Detailed examination of four sediment fractions between 63–500 μm showed that benthic foraminiferal assemblages (undifferentiated living + dead) collected from 23 surface-sediment samples along the Marmara Sea coast were dominated by smaller (<250-μm) individuals, averaging 95% of the total fauna. Higher foraminiferal density, species diversity, and restricted size frequency of some species within the 63–250-μm fraction indicate that different lower sieve limits will cause a significant variation in the composition of local assemblages. ......

==TAXONOMY AND PHYLOGENY OF THE TROCHOLINIDAE (INVOLUTININA)==

[[Image:JFR_cover.gif‎|left|80px|]]<font size="2">
 +
Exceptionally well-preserved trochospirally coiled Involutinina have been found in Late Triassic (Wallowa Mountains, Oregon, U.S.A.) and Early Jurassic (northern Calcareous Alps, Austria) carbonate rocks. Their remarkable preservation, related to impregnation of the test prior to recrystallization, allowed us to observe features usually obliterated by diagenetic and metamorphic processes. This paper provides a revision of the morphology, structure, systematic position, phylogeny, and stratigraphic range of the family Trocholinidae Kristan-Tollmann. New criteria permitting the distinction between trocholinid genera, even in cases of intense recrystallization, are presented. An identification key and a new, monophyletic tree are proposed for the whole family. ......

==CALCIFICATION INTENSITY IN PLANKTONIC FORAMINIFERA REFLECTS AMBIENT CONDITIONS IRRESPECTIVE OF ENVIRONMENTAL STRESS==
 +
 
 +
[[Image:Biogeosciences_front.jpg‎‎|left|80px|]]<font size="2">
 +
...... The amount of calcite deposited by planktonic Foraminifera during calcification has been hypothesized to reflect a range of environmental factors. However, it has never been assessed whether their calcification only passively responds to the conditions of the ambient seawater or whether it reflects changes in resource allocation due to physiological stress. To disentangle these two end-member scenarios, an experiment is required where the two processes are separated. A natural analogue to such an experiment occurred during the deposition of the Mediterranean sapropels, where large changes in surface water composition and stratification at the onset of the sapropel deposition were decoupled from local extinctions of planktonic Foraminifera species. We took advantage of this natural experiment and investigated the reaction of calcification intensity, expressed as mean area density (MAD), of four species of planktonic Foraminifera to changing conditions during the onset of Sapropel S5 (126–121 ka) in a sediment core from the Levantine Basin. ...... These results indicate that the high-salinity environment of the glacial Mediterranean Sea prior to sapropel deposition induced more intense calcification, whereas the freshwater injection to the surface waters associated with sapropel deposition inhibited calcification. The results are robust to changes in carbonate preservation and collectively imply that changes in normalized shell weight in planktonic Foraminifera should reflect mainly abiotic forcing.

==EFFECT OF OCEAN ACIDIFICATION ON ''Ammonia'' sp.==
 +
 
 +
[[Image:Biogeosciences_front.jpg‎‎|left|80px|]]<font size="2">
 +
About 30% of the anthropogenically released CO<sub>2</sub> is taken up by the oceans; such uptake causes surface ocean pH to decrease and is commonly referred to as ocean acidification (OA). Foraminifera are one of the most abundant groups of marine calcifiers, estimated to precipitate ca. 50 % of biogenic calcium carbonate in the open oceans. We have compiled the state of the art literature on OA effects on foraminifera, because the majority of OA research on this group was published within the last three years. Disparate responses of this important group of marine calcifiers to OA were reported, highlighting the importance of a process-based understanding of OA effects on foraminifera. We cultured the benthic foraminifer ''Ammonia'' sp. under a range of carbonate chemistry manipulation treatments to identify the parameter of the carbonate system causing the observed effects. This parameter identification is the first step towards a process-based understanding. We argue that [CO<sub>3</sub><sup>2−</sup>] is the parameter affecting foraminiferal size-normalized weights (SNWs) and growth rates. Based on the presented data, we can confirm the strong potential of ''Ammonia'' sp. foraminiferal SNW as a [CO<sub>3</sub><sup>2−</sup>] proxy.

==MULTIDISCIPLINARY STUDY OF RARELY RECOVERED PARTS OF DEEP-SEA SANTONIAN-CAMPANIAN TRANSITION==
 +
 
 +
<font size="2">
 +
The Cretaceous deep-sea record of the Santonian–Campanian transition is commonly interrupted by an extensive unconformity (representing <10 Myr of hiatus). The resultant palaeoceanographic gap can now be partly bridged by a recent short core of pelagic ooze from Shatsky Rise (Integrated Ocean Drilling Program (IODP) Site U1348), with precise multidisciplinary age constraints developed herein. New oxygen isotope data from very well-preserved benthic foraminifera, together with accurately compiled comparable benthic data from previous Pacific deep-sea sections, exhibit a large (c. +1‰) early Campanian shift. We propose the Santonian–Campanian climatic transition was not gradual but was the first major cooling step after sustained mid-Cretaceous hothouse conditions.

==THE CRETACEOUS-TERTIARY BOUNDARY TRANSITION IN NE BRAZIL==
 +
 
 +
<font size="2">
 +
At 7800 km from Yucatan the Cretaceous–Tertiary boundary (KTB) transition of the Poty Quarry, NE Brazil, is the most distant locality with published accounts of Chicxulub impact–tsunami deposits, impact spherules and Ir anomaly. New investigations based on sedimentology, biostratigraphy, mineralogy and geochemistry fail to confirm these reports. Latest Maastrichtian planktic foraminiferal zones CF1 below an erosive and bioturbated disconformity and early Danian zone P1a(1) above indicate a short hiatus, with the KTB clay (zone P0), the Ir anomaly and the characteristic negative δ<sup>13</sup>C excursion missing. The disconformity coincides with the globally recognized latest Maastrichtian sea-level fall. Above the disconformity, an upward-fining micro-conglomerate with abundant reworked Cretaceous foraminifera, sub-angular phosphate clasts, calcitic and phosphatic spheroids along with an early Danian zone P1a(1) assemblage is interpreted as a gravity-flow deposit. Common spheroids throughout the late Campanian–Maastrichtian appear to be chamber infillings of the benthic foraminifer ''Dentalina alternata''. Minor Ir anomalies in thin clay layers of zone Pla and no evidence of the Chicxulub impact reveal that the Poty Quarry section remains a very important example of the complex global environmental and sea-level changes observed in KT sequences from North America to Central America that are commonly misinterpreted as impact–tsunami events.

Access to new material from South Africa, Corsica, Cyprus, Syria and Sumatra has allowed a systematic biostratigraphic comparison and correlation of the miogypsinids from the Mediterranean–West Africa and the Indo-Pacific provinces, and for the first time from South Africa. Twelve new species have been identified ......During the Chattian and Aquitanian significant miogypsinid forms evolved in the Mediterranean from the morphologically distinct Mediterranean ''Neorotalia'' and migrated, within a few million years of their first appearance, into the Indo-Pacific, where they diversified further. The tectonically driven closure of the seaway between the Mediterranean and the Indo-Pacific in the Burdigalian triggered the extinction of Mediterranean miogypsinids in the Langhian. Miogypsinids survived in the Indo-Pacific into the Serravallian.

The foraminiferal and radiolarian biostratigraphy of selected sections of the Zabijak Formation, the youngest sediments of the Tatra massif (Central Western Carpathians), have been studied. Benthic foraminifers, mainly agglutinated species, occur abundantly and continuously throughout the studied succession, while planktic foraminifers are generally sparse. Five planktic and two benthic foraminiferal zones have been recognized. The marly part of the Zabijak Formation comprises the ''Pseudothalmanninella ticinensis'' (Upper Albian) through the ''Rotalipora cushmani'' (Upper Cenomanian) planktic foraminiferal zones, and the ''Haplophragmoides nonioninoides'' and ''Bulbobaculites problematicus'' benthic foraminiferal zones. The radiolarians were recognized exclusively in the Lower Cenomanian part of the formation.

==NEW SUPRAORDINAL CLASSIFICATION OF FORAMINIFERA: MOLECULES MEET MORPHOLOGY==
  
 +
[[Image:Marine_Micropaleontology_Front.gif‎‎ |left|80px|]]<font size="2">
 +
The limitations of a traditional morphology-based classification of Foraminifera have been demonstrated by molecular phylogenetic studies for several years now. Despite the accumulation of molecular data, no alternative higher-level taxonomic system incorporating these data has been proposed yet. Here, we present a new supraordinal classification of Foraminifera based on an updated SSU rDNA phylogeny completed with the description of major morphological trends in the evolution of this group. According to the new system, multi-chambered orders are grouped in two new classes: [[Tubothalamea|Tubothalamea]] and [[Globothalamea|Globothalamea]]. Naked and single-chambered Foraminifera possessing agglutinated or organic-walled tests are arranged into a paraphyletic assemblage of “[[monothalamids|Monothalamids]]”. The new system maintains some multi-chambered calcareous orders, such as Rotaliida, Miliolida, Robertinida and Spirillinida, although their definitions have been modified in some cases to include agglutinated taxa. The representatives of the planktonic order Globigerinida are tentatively included in the order Rotaliida. The agglutinated Textulariida are probably paraphyletic. The position of the order Lagenida is uncertain because reliable molecular data are only available for one species. The new classification system separates orders or families, which differ in basic chamber shapes, prevailing mode of coiling and distance between successive apertures. It appears that these features correspond better to the main evolutionary trends in Foraminifera than wall composition and structure, both used in traditional classification.

[[Image:Geology_cover.gif‎|left|80px|]]<font size="2">
 +
A shift from the icehouse climate in which humans evolved to a Late Cretaceous–like greenhouse climate is an often-repeated cautionary prediction of the consequences of continued anthropogenic CO<sub>2</sub> emissions. The corollary, that understanding the past might help predict the future, has justified many Late Cretaceous studies, but important questions remain about climate stability and sensitivity. New δ<sup>18</sup>O measurements of more than 1000 samples of exceptionally well preserved foraminifera (8 planktic and 11 benthic taxa) from two sites in Tanzania indicate that hot and remarkably stable conditions prevailed in the region during the Turonian, including during a proposed greenhouse glacial event. Planktic taxa have δ<sup>18</sup>O values largely between –4.0‰ and –5.0‰, suggesting surface-water temperatures between 30 and 35 °C. Estimates for seafloor temperatures are between 18 and 25 °C. No parallel shifts in δ<sup>18</sup>O values are observed among planktic and benthic taxa, contradicting an often-cited line of evidence for greenhouse glaciations and supporting an effectively ice-free Turonian world.

==TESTING THE USE OF FORAMINIFERA TO RECONSTRUCT EARTHQUAKES==
 +
 
 +
[[Image:Geology_cover.gif‎|left|80px|]]<font size="2">
 +
Coastal stratigraphy from the Pacific Northwest of the United States contains evidence of sudden subsidence during ruptures of the Cascadia subduction zone. Transfer functions (empirical relationships between assemblages and elevation) can convert microfossil data into coastal subsidence estimates. Coseismic deformation models use the subsidence values to constrain earthquake magnitudes. To test the response of foraminifera, the accuracy of the transfer function method, and the presence of a pre-seismic signal, we simulated a great earthquake near Coos Bay, Oregon, by transplanting a bed of modern high salt-marsh sediment into the tidal flat, an elevation change that mimics a coseismic subsidence of 0.64 m. The transplanted bed was quickly buried by mud; after 12 mo and 5 yr, we sampled it for foraminifera. Reconstruction of the simulated coseismic subsidence using our transfer function was 0.61 m, nearly identical to the actual elevation change. Our transplant experiment, and additional analyses spanning the A.D. 1700 earthquake contact at the nearby Coquille River 15 km to the south, show that sediment mixing may explain assemblage changes previously interpreted as evidence of pre-seismic land-level change in Cascadia and elsewhere.

==DIVERSIFICATION PATTERNS OF PLANKTIC FORAMINIFERA IN THE FOSSIL RECORD==
 +
 
 +
[[Image:Marine_Micropaleontology_Front.gif‎‎ |left|80px|]]<font size="2">
 +
Theories of taxonomic diversification dispute whether global diversity has an upper limit set by the strength of biological interactions or grows in unlimited fashion until catastrophic events reset the system. We analyzed a global compendium of fossil planktic foraminifera from the early Cretaceous to the present after correcting for temporal differences in sampling effort. Our results show that their morphological diversity has increased exponentially through time in two different phases. The first phase collapsed at the Cretaceous-Paleogene boundary transition. The second phase developed through the Cenozoic era and declined during the Pliocene-Pleistocene interval, a period of time that was dominated by enhanced climatic and oceanographic instability. In none of these phases diversity reached an equilibrium level. Cenozoic faunas evolved faster than those inhabiting Cretaceous oceans, perhaps as a result of a higher environmental variability. Our results indicate that planktic foraminifera conform to an exponential diversification model. However, because catastrophic events have repeatedly reset the level of biological diversity and have kept it below the maximum, we cannot confirm whether the level of diversity is potentially unlimited.

==ALTERNATIVE HYPOTHESES TO EXPLAIN THE EXTINCTION DURING THE MID-PLEISTOCENE CLIMATE TRANSITION==
 +
 
 +
[[Image:Marine_Micropaleontology_Front.gif‎‎ |left|80px|]]<font size="2">
 +
Over 100 cosmopolitan species of deep-sea benthic foraminifera (Extinction Group, Ext. Gp) became extinct during the late Pliocene-middle Pleistocene (3.6-0.55 Ma). Most had elongate, cylindrical tests and terminal apertures with complex modifications. This study provides new hypotheses on the functions of the morphologies that characterised the Ext. Gp and how these features could have been associated with their demise. From our functional morphological analysis we infer that: i) their elongate cylindrical or flabelliform tests, combined with fine perforations and a complex terminal apertural face are indicative of infaunal k-strategists with a low rate of metabolism; ii) their complex apertural faces may also have been an adaptation for gathering or processing their specific phytodetrital food. ......  <br/>
 +
'''Highlights'''
 +
• Functional interpretation of the morphology of deep-sea foraminifera that became extinct during the MPT (Ext. Gp) suggests they had low rates of metabolism.
 +
• Lowered ''p''CO<sub>2</sub> during increasingly severe glacials of the mid-Pleistocene Climate Transition resulted in the decline and loss of many reticulofenestrid nannofossils and increased seasonality of phytoplankton blooms.
 +
• Ext. Gp species may have been out-competed by opportunistic benthic foraminifera that took advantage of the increased seasonality of phytodetrital flux to the deep-sea floor.
 +
• Lowered ''p''CO<sub>2</sub>  could have caused the loss of the particular phytoplankton group that was the detrital food of the Ext. Gp.

==AGGLUTINATED FORAMINIFERA ACROSS THE INDIAN MARGIN OMZ (ARABIAN SEA)==
 +
 
 +
<font size="2">
 +
We present a semi-quantitative survey of ‘live’ (stained) and dead hormosinacean foraminifera at six sites (500–2,000 m water depth; bottom-water oxygen concentrations 0.007–2.43 ml L<sup>−1</sup>) across the Indian margin oxygen minimum zone (OMZ). Abundance of stained and dead specimens was highest at 800 m followed by 1,100 m, lowest at 2,000 m (stained) and 500 m (dead). The peak at 800 m possibly represents a release from oxygen stress combined with a rich food supply (‘edge effect’). We recognised 31 species (27 ''Reophax'', 2 ''Hormosinella'', 1 ''Hormosina'' and 1 ''Nodosinella'') among the 605 stained and dead specimens; the majority (21) are apparently undescribed.  Species richness was low at 2,000 m; within the OMZ, it was maximal at 1,100 m and minimal at 500 m for both stained and dead populations. Three species (''R. agglutinatus'', ''R''. aff. ''bilocularis'' and ''R. dentaliniformis'') occurred across the entire depth range. However, most species were either confined to the 2,000-m site or to one or more sites within the OMZ. Multivariate analysis of assemblage composition revealed that the 2,000-m site was distinct from shallower sites. Within the OMZ, the 900- and 1,100-m sites were the most similar, and the 500-m site the most distinct. Stained:dead test ratios were maximal at 500–835 m, perhaps reflecting enhanced preservation of cytoplasm at very low oxygen concentrations. At least two Reophax species are common to the Indian and Pakistan margin OMZ; one of these may be confined to the core of the Arabian Sea OMZ.

==FORAMINIFERAL RESPONSE TO TRACE ELEMENT POLLUTION, THE GULF OF MILAZZO, NE SICILY==

<font size="2">
 +
The response of benthic foraminiferal assemblages to trace element pollution in the marine sediments of the Gulf of Milazzo (north-eastern Sicily) was investigated. Since the 1960s, this coastal area has been a preferred site for the development of two small marinas and a commercial harbour as well as for heavy industry. Forty samples collected in the uppermost 3–4 cm of an undisturbed layer of sediment in the littoral environment were used for this benthic foraminiferal analysis. The enrichment factors (EFs) of selected trace elements (As, Co, Cr, Cu, Mn, Ni, Pb and Zn) were also calculated. Changes both in benthic foraminiferal assemblages and in some trace elements concentrations have provided evidence that the gulf’s littoral zone can be subdivided into three sectors characterised by environmental changes in the marine ecosystem. ......

[[Image:RevueDeMicropaleontologie_front.gif|left|80px| ]]<font size="2"> ...... the systematics, evolution and ecological behaviour of the first mineralized Palaeozoic Foraminifera are important to discuss in order to have a clearer picture of former shallow marine environments, and finally understand their distribution through space and time. The systematics of the fossil group of Foraminifera that first developed a mineralized test remains under discussion. These early foraminifers are considered as Textulariata (as generally admitted), recrystallized Fusulinata or an independent group, sometimes called Astrorhizata. In this paper, we argue to assign the early foraminifers to the Fusulinata, and to subdivide this class into six orders: Parathuramminida, Archaediscida and Earlandiida (forming together the subclass Afusulinana n. subcl.), and Tournayellida, Endothyrida and Fusulinida (subclass Fusulinana nom. translat.). These subdivisions are discussed and linked to the first occurrences of the later classes: Miliolata, Nodosariata and Textulariata.

The timing of vertical migration in planktonic foraminifera (ex. ontogenetic, diel) is still an open debate. This work aims to investigate the diel vertical migration (DVM) of ''Neogloboquadrina pachyderma'' (''N. pachyderma'') and ''Turborotalita quinqueloba'' (''T. quinqueloba'') in the Arctic during the midnight sun. ''N. pachyderma'' and ''T. quinqueloba'' dominate the total assemblage in the cold Polar Water and warmer North Atlantic Water masses, respectively. Foraminifera were collected at several depths along the Fram Strait. Afterwards sampling was performed at the same station for 24 h at continuous and discrete time intervals. Results show no evidence of planktonic foraminifera DVM since there was no significant variability in the abundance and size distribution during the 24-h collection period. This finding provides information to improve the interpretation of foraminifera in paleoclimatic works. This is especially relevant in the Fram Strait as paleoclimatic studies in this region are fundamental to investigating the history of the Atlantic water inflow into the Arctic Ocean.

Only one lagoon assemblage is present in both atolls, which is characterized by abundant Ammonia sp. 1 and smaller miliolid foraminifera. ......  The assemblages compare well with sedimentological characteristics, which is also reflected in their distributions. Species diversity in the Maldives appears to be higher than the western Indian Ocean region due to the stronger influence of central Indo-Pacific faunas. It is not however, as high as the central Indo-Pacific region, which may be due to lower habitat diversity.

...... We compare stratigraphic ranges of ammonite and foraminiferal species in Pliensbachian–Toarcian successions of western North America to the record in Europe and parts of the Arctic in order to test the geographic extent of the multiple phases of extinction. Our results show six intervals of species level decline that correlate with those recognized in Europe. ...... Recognition of this multi-phased event in three separate ocean basins (paleo Pacific, paleo Arctic, and Tethys Oceans), in at least two taxonomic groups, greatly expands the known geographic extent of this multi-phased event and argues for a controlling mechanism that is global in its reach. In relation to the Volcanic Greenhouse Scenario, our study shows that four of the six pulses of extinction occur within the main-phase of Karoo magmatism. The decline in the Early Pliensbachian, previously thought to be separate from this event, occurs within error range of the onset of Karoo magmatism and the decline in the Late Toarcian coincides with the later stages of magmatism. These observations extend the known duration of this multi-phased extinction event to the Early Pliensbachian and support the Volcanic Greenhouse Scenario, specifically the eruption of the Karoo–Ferrar LIP, as a preeminent factor driving the multi-phased extinction of the Pliensbachian–Toarcian.

Agglutinated foraminifera from the Lower and lower part of the Middle Devonian, predominantly limestones of the Prague Synform (Barrandian area), were classified into five morphogroups ...... The absence of the deep infaunal morphogroups is characteristic. The morphogroup distribution has been strongly affected by oxygen concentration, the energy of the environment, nutrient availability and post-mortem processes. Intervals with diversified and abundant foraminiferal assemblages can be correlated with positive δ<sup>13</sup>C excursions and also with the deposition of nodular limestones. The Devonian assemblages from the Prague Synform were compared with isochronous assemblages from other regions. Though the taxonomical composition of the Early Devonian assemblages from these areas are rather different, the morphogroup composition is highly comparable, and globally indicates similar life and feeding strategies of the Early Devonian foraminifera.

[[Image:J_Sea_Research_Front.gif|left|80px| ]]<font size="2">In this paper, we investigate the ecology of live (rose Bengal stained) benthic foraminifera collected at 20 stations ranging from 15 to 100 m depth in the Rhône prodelta (Gulf of Lions, NW Mediterranean). These sites were sampled in September 2006, five months after the Rhône River annual flood. Statistical analyses based on foraminiferal communities (N150 µm) divide our study area into six main biofacies directly related to environmental conditions. ...... We also compare foraminiferal faunas sampled in September 2006 with communities sampled in June 2005, one month after the Rhône River annual flood (Mojtahid et al., 2009). This comparison suggests that opportunistic species (e.g. B. aculeata, Cassidulina carinata, V. bradyana) have responded to organic matter inputs related to marine primary production in June 2005.

...... To better assess the global versus local contribution in a δ<sup>13</sup>C record it is necessary to compare numerous isotopic records on a global scale. As a contribution to this objective, this paper reviews bulk sediment δ13Ccarb records from the Late Cretaceous in order to identify differences and similarities in secular δ<sup>13</sup>C trends that help establish a global reference δ<sup>13</sup>C record for this period. The study presents a global-scale comparison of twenty δ<sup>13</sup>C records from sections representing various palaeo-latitudes in both hemispheres and different oceanic settings from the Boreal, Tethys, Western Interior, Indian Ocean and Pacific Ocean, and with various diagenetic overprinting. The isotopic patterns are correlated based on independent dating with biostratigraphic and paleomagnetic data and reveal good agreement of the major isotope events despite offsets in absolute δ<sup>13</sup>C values and variation in amplitude between the sites. ...... The combination of chemostratigraphy with biostratigraphy and magnetostratigraphy substantially increases the precision and temporal resolution of inter-regional correlations and helps overcome problems that arise from differences in biostratigraphic schemes, facies or provincialism of key fossils. By using an iterative approach to stepwise increase precision of the correlations, isochroneity of first and last occurrences of marker species versus chemostratigraphy is tested, which helps to improve biostratigraphic zonations, to assess zonal boundary ages and to identify useful criteria for defining Late Cretaceous stage boundaries, many of which are still not formally defined. The presented correlations indicate a consistent position for most planktic foraminifer zonal boundaries relative to corresponding isotope shifts during the mid-Cretaceous sea-level high, whereas diachroneity appears to be more pronounced during the Late Campanian and Maastrichtian global sea-level fall. A similar pattern is observed for trans-continental consistency in the δ<sup>13</sup>C shifts. Graphic correlation of isotopic shifts, magnetostratigraphic and biostratigraphic events among the compared sections is used to detect hiatuses or relative changes sediment accumulation rates and visualizes consistency or offsets of individual biostratigraphic markers relative to chemo- and magnetostratigraphy. Finally, an attempt of a global average δ<sup>13</sup>C stack is presented for the Turonian through Maastrichtian.

The radiogenic neodymium (Nd) isotope composition of foraminiferal shells provides a powerful archive to investigate past changes in sources and mixing of water masses. However, seawater Nd isotope ratios extracted from foraminiferal shells can be biased by contaminant phases such as organic matter, silicates, or ferromanganese coatings, the removal of which requires rigorous multiple step cleaning of the samples. Here we investigate the efficiency of Flow Through and batch cleaning methods to extract seawater Nd isotope compositions from planktonic foraminifera in a shelf setting in the Gulf of Guinea that is strongly influenced by riverine sediment inputs. Nd isotope analyses of reductively and oxidatively cleaned mono-specific planktonic foraminiferal samples and reductively cleaned mixed benthic foraminifera were complemented by analyses of non-reductively cleaned mono-specific planktonic foraminiferal samples, Fe–Mn coatings of de-carbonated bulk sediment leachates, and the residual detrital fraction of the same sediment. ......

Making the link between evolutionary processes and development in extinct organisms is usually hampered by the lack of preservation of ontogenetic stages in the fossil record. Planktic foraminifers, which grow by adding chambers, are an ideal target organism for such studies as their test incorporates all prior developmental stages. Previously, studies of development in these organisms were limited by the small size of their early chambers. Here, we describe the application of synchrotron radiation X-ray tomographic microscopy (SRXTM) to document the ontogenetic history of the foraminifers ''Globigerinoides sacculifer'' and ''Globorotalia menardii''. Our SRXTM scans permit resolution at submicrometre scale, thereby displaying additional internal structures such as pores, dissolution patterns and complexity of the wall growth. Our methods provide a powerful tool to pick apart the developmental history of these microfossils and subsequently assist in inferring phylogenetic relationships and evolutionary processes.

''Pararotalia boixae'' sp. nov. comprises specimens previously attributed to ''P. tuberculifera'' Reuss 1862 pro parte. This Cenomanian new species (with Campanian affinis forms) is characterized by morphological features that clearly distinct it from the type of Reuss.

The Elphidiidae represent one of the most abundant and diversified foraminiferal family in shallow water habitats worldwide. Playing crucial roles in diverse ecosystems, they occur since the Eocene to present and are widely used for paleoenvironmental reconstructions. However, the lack of a clear taxonomic consensus led to a vast confusion concerning the relation of Elphidiidae with other rotaliids, in particular Nonionidae (''Haynesina'') and Rotaliidae (''Ammonia''). Moreover, high morphological plasticity of the test prevented the establishment of a clear definition for many species and genera of this family. Here, 66 new sequences of the SSU rRNA gene were obtained and used to build an extensive dataset including 94 complete or partial sequences of the SSU rDNA of 17 different morphospecies of ''Elphidiidae'', ''Haynesina'' and ''Ammonia''.  ...... <BR/>

The Santonian–Campanian interval is of particular interest as it encompasses a cooling trend after the Late Cretaceous greenhouse maximum warmth of the Turonian as well as a possibly related major faunal turnover among planktonic foraminifera. The recovery of pristinely preserved planktonic foraminifera from Santonian–Campanian sequences in southeastern Tanzania allows examination of faunal changes and documentation of species-specific stable isotope (δ<sup>13</sup>C and δ<sup>18</sup>O) signatures. These isotopic data are ideal for inferring species paleoecological preferences and for tracing major paleoceanographic changes. This study reports the first δ<sup>18</sup>O and δ<sup>13</sup>C data generated on “glassy” specimens of ''Marginotruncana coronata'', ''M. undulata'', ''M. marginata'', and ''M. pseudolinneiana'' and ''Sigalia carpatica''.

This paper compares the distribution and diversity patterns of benthic foraminifera (all taxa and only calcareous forms) and macrozoobenthos in an Arctic glacial fjord. The samples were collected at 22 stations located in Hornsund (west Spitsbergen). The activity of tidal glaciers located in the inner basins causes steep environmental gradients of turbidity, organic matter supply, and sediment stability. Clear differences in density, diversity and species composition were documented for both foraminifera and macrofauna between the groups of stations located in three zones along a gradient of increasing tidal glacier impact. ...... Our study provides evidence that the patterns of calcareous foraminifera density, diversity and species composition in a glacial fjord can be effective, reliable indicators of variability of these characteristics in other benthic compartments.<br/>
 +
'''Highlights'''
 +
•We compared responses of Foraminifera and macrofauna to glacial impacts.
 +
•Patterns of species distribution in two groups in a glacial fjord were correlated.
 +
•Species richness and density of both groups declined towards glaciers.
 +
•Foraminifera can be a useful indicator of other benthic groups variability.

[[Image:Marine_Micropaleontology_Front.gif|left|80px|]]<font size="2">
 +
The Shuaiba Lagoon is a fossil back-reef, hypersaline small basin located 80 km south of Jeddah city on the eastern Red Sea coast, Saudi Arabia. The surface sediments of the lagoon were investigated for their benthic foraminiferal content in order to correlate, in general, with environmental factors such as temperature, salinity, pH, sediment grain size, organic matter and, in particular, with tidal elevations to develop a training set for predicting sea-level changes in the lagoon. Hierarchical cluster analysis divided the benthic foraminifera in the Shuaiba Lagoon into four distinct faunal assemblages. ...... <br/>
 +
'''Highlights'''
 +
•Foraminiferal assemblages and their factors in the Shuaiba Lagoon were investigated.
 +
•Each of these assemblages occupied a distinct elevational zone in the lagoon.
 +
•Intertidal-high subtidal assemblages could predict the sea level change with ± 0.16 m.
 +
•Low subtidal-deep water assemblages were deleterious on the TF giving a wide error.
 +
•The pH controlled the distribution abundances of the symbiont-bearing assemblages.

Fossil remnants of benthic foraminifera consist of carbonate tests and their organic linings. The macromolecular and stable isotopic composition of these benthic foraminiferal organic linings was characterized to evaluate their potential use as paleoclimate proxies. Using Curie point pyrolysis–GC–MS (Py–GC–MS) we show that benthic foraminiferal organic linings consist of protein and polysaccharides, bound together in a complex macromolecular structure.  ...... <BR/>

We describe the spatial distribution of recent benthic foraminifer assemblages from the western area of the Basque shelf in relation with some environmental parameters. A total of 138 species have been identified, being the most abundant Cassidulina laevigata, Gaudryina rudis, Lobatula lobatula, Rosalina globularis and Textularia sagittula. Multivariate analyses (cluster Q-type and Detrended and Canonical Correspondence Analysis) performed with the benthic foraminifers of these samples show the separation of two main groups of species related with the sediment grain size: (1) coarse to very coarse sand and (2) medium sand and sandy silt. Seven clusters are characterised by their typical foraminifer assemblage and average values of particular parameters: clay-silt content of the sediment, depth, and percentage of foraminifer species indicative of hypoxia. The main features of marine currents of the area are reflected by these foraminifer assemblages. ......

The foraminiferal and radiolarian biostratigraphy of selected sections of the Zabijak Formation, the youngest sediments of the Tatra massif (Central Western Carpathians), have been studied. Benthic foraminifers, mainly agglutinated species, occur abundantly and continuously throughout the studied succession, while planktic foraminifers are generally sparse. Five planktic and two benthic foraminiferal zones have been recognized. The marly part of the Zabijak Formation comprises the ''Pseudothalmanninella ticinensis'' (Upper Albian) through the ''Rotalipora cushmani'' (Upper Cenomanian) planktic foraminiferal zones, and the ''Haplophragmoides nonioninoides'' and ''Bulbobaculites problematicus'' benthic foraminiferal zones. The radiolarians were recognized exclusively in the Lower Cenomanian part of the formation.

The aim of the present study was to compare preservation, staining and preparation techniques to assess the influence of different sample treatments and analyses on the accuracy of benthic foraminiferal assemblage data from NE Atlantic shelf seas. Replicate surface samples from the SE North Sea were preserved with ethanol–rose Bengal or formalin, some were stained after processing, or foraminifera were concentrated by flotation. ...... Population density varied between different preservation, picking modes and investigators. The accuracy of picking was in the range of ±2 % (1σ), while external reproducibility ranged from −34 to +16 %. There was no significant difference between wet and dry picking. Samples that were concentrated by flotation generally yielded a lower number of specimens. Agglutinated species were under-represented in samples that were stained after washing and in the flotation concentrate. Size fractions showed a reduction of population density and Fisher alpha diversity index with increasing mesh size. Only half of the specimens and less than two-thirds of the species are captured if the >125 µm rather than >63 µm fraction is analysed.

The study deals with environmental changes during the Paleocene-Eocene Thermal Maximum (PETM) and its background conditions in Spitsbergen through analysis of benthic foraminiferal assemblages (FA) in a section drilled in the Paleogene Central Basin. The impact of this extreme global warming occurs here in prodelta shelf mudstones composing the lower part of the Gilsonryggen Member (Frysjaodden Formation). The start of the PETM perturbation is marked by a faunal turnover, in which the medium-diversity circumpolar ''Reticulophragmium'' assemblage was replaced by a low-diversity ''Trochammina'' fauna. During the hyperthermal period, benthic foraminiferal diversity decreased severely, while the dominance of small-sized taxa with epifaunal morphology strongly increased. This low-diversity fauna occurs in sediments with a reduced thorium/uranium ratio (proxy for oxygenation) and kaolinite enrichment (proxy for high humidity). The faunal changes were thus caused by the combined effects of hypoxic and hyposaline conditions in a stratified water column, due to extreme warming with its accompanying intensified hydrologic cycle. ......

The discovery that foraminifera are able to use nitrate instead of oxygen as an electron acceptor for respiration has challenged our understanding of nitrogen cycling in the ocean. It was thought before that only prokaryotes and some fungi are able to denitrify. Rate estimates of foraminiferal denitrification have been very sparse and limited to specific regions in the oceans, not comparing stations along a transect of a certain region. Here, we present estimates of benthic foraminiferal denitrification rates from six stations at intermediate water depths in and below the Peruvian oxygen minimum zone (OMZ). Foraminiferal denitrification rates were calculated from abundance and assemblage composition of the total living fauna in both surface and subsurface sediments, as well as from individual species specific denitrification rates. ......

The foraminifer ''Spiculosiphon oceana'' sp. nov. is a giant (>4 cm) agglutinated astrorhizid, which makes the second known species of this unusual genus and its first Mediterranean record. It has a peculiar stalked, capitate, monothalamous test. Bleach digestion and X-ray microanalysis indicated the test to be made exclusively of siliceous sponge spicules agglutinated in organic cement. The organism stands on a hollow, 4 cm long, 0.5 cm thick stalk built with highly selected, long and thin spicule fragments, tightly cemented together in parallel to the main axis of the stalk. ...... ''Spiculosiphon'' species collect and arrange sponge spicules with high selectivity to recreate a body morphology that strongly converges to that of some carnivorous sponges, which allows these predatory foraminifera to exploit a prey capturing strategy similar to that of the carnivorous sponges. This idea is also consistent with our report of an additional, yet undetermined, ''Spiculosiphon'' species occurring in the same sublittoral Mediterranean cave where carnivorous sponges were first discovered.

...... Considerable knowledge exists about prokaryotic composition of microbialite mats (i.e., stromatolitic and thrombolitic mats), but little is known about their eukaryotic communities, especially regarding heterotrophic taxa. Thus, the heterotrophic eukaryotic communities of Highborne stromatolites and thrombolites were studied. Here, we show that diverse foraminiferal communities inhabit microbialite mat surfaces and subsurfaces; thecate foraminifera are relatively abundant in all microbialite types, especially thrombolitic mats; foraminifera stabilize grains in mats; and thecate reticulopod activities can impact stromatolitic mat lamination. Accordingly, and in light of foraminiferal impacts on modern microbialites, our results indicate that the microbialite fossil record may reflect the impact of the radiation of these protists.

Early Jurassic aragonitic foraminifers are outstandingly well-preserved in the Marmorea crust, a multiphased ferromanganese layer limiting the Schnöll and Adnet formations (Adnet, Northern Calcareous Alps, Austria). This remarkable preservation, related to the pervasive impregnation of aragonitic tests prior to their recrystallization, allowed observing unknown diagnostic features of the genus ''Involutina'', which typifies the Suborder Involutinina. Thanks to a detailed examination of the Adnet specimens, this paper clarifies the taxonomy, systematic position, and phylogeny of ''Involutina''.  ......

==MIDDLE MIOCENE WARM-TEMPERATE CARBONATES OF CENTRAL PARATETHYS (MT. ZRINSKA GORA, CROATIA): PALEOENVIRONMENTAL RECONSTRUCTION==
  
{{Alve & Goldstein (2010)}}
+
Carbonate deposits from Zrin in the Mt. Zrinska Gora were deposited in the SW part of the Central Paratethys Sea during the Middle Badenian (Middle Miocene). The studied section contains a rich fossil community of non-geniculate coralline red algae (Subfamily Melobesioideae), bryozoans, benthic and planktonic foraminifera, echinoderms, ostracods, molluscs, and calcareous nannoplankton. Based on lithological variations and changes in the biogenic components, four facies associations (FA) are distinguished. Their distribution points to skeletal production and sedimentation on a middle to proximal outer carbonate ramp. The main lithological feature of the section is an alternation of two lithofacies: fully lithified grainstone–rudstone and packstone, and semi-lithified rudstone–floatstone with a carbonate sandy matrix. ......
