==MIDDLE EOCENE ABYSSAL BENTHIC FORAMINIFERA IN THE EASTERN EQUATORIAL PACIFIC==
 +
 +
[[Image:Journal_Of_Paleontology_cover.jpg‎ ‎|left|80px|]]<font size="2">

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.

==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.

==A STABLE AND HOT TURONIAN WITHOUT GLACIAL ∂<sup>18</sup>O EXCURSIONS==

[[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.

==TRACE ELEMENT POLLUTION - THE CASE STUDY OF THE GULF OF MILAZZO, NE SICILY==
 
 
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. ...... Deformed foraminifera, with percentages up to 7.14 %, were found in all three of the sectors. Differences in benthic foraminiferal assemblages, coupled with results from statistical analysis, indicate that anthropogenic trace element pollution could be considered as one of the most important causes of the modifications of foraminiferal assemblages in the study area.

==THE LITTLE ICE AGE: EVIDENCE FROM A SEDIMENT RECORD IN GULLMAR FJORD, SWEDEN==
 
 
[[Image:Biogeosciences_front.jpg‎ ‎‎|left|80px|]]<font size="2">
 
We discuss the climatic and environmental changes during the last millennium in NE Europe based on a ca. 8-m long high-resolved and well-dated marine sediment record from the deepest basin of Gullmar Fjord (SW Sweden). According to the <sup>210</sup>Pb- and <sup>14</sup>C-datings, the record includes the period of the late Holocene characterised by anomalously cold summers and well-known as the Little Ice Age (LIA). Using benthic foraminiferal stratigraphy, lithology, bulk sediment geochemistry and stable carbon isotopes we reconstruct various phases of the cold period, identify its timing in the study area and discuss the land–sea interactions occurring during that time. The onset of the LIA is indicated by an increase in cold-water foraminiferal species ''Adercotryma glomerata'' at ~ 1350 AD The first phase of the LIA was characterised by a stormy climate and higher productivity, which is indicated by a foraminiferal unit of ''Nonionella iridea'' and ''Cassidulina laevigata''. ......

==TIMING AND SIZE SELECTIVITY OF THE GUADALUPIAN FUSULINOIDEAN EXTINCTION==
 
 
[[Image:Journal_Of_Paleontology_cover.jpg‎‎|left|80px|]]<font size="2">
 
A comprehensive, high resolution stratigraphic database of fusulinoidean foraminifers reveals that this group of protists suffered extreme losses during the Guadalupian extinction. Most species (88%) were eliminated gradually over the course of 9 myr during the Wordian and Capitanian ages. A pulse of greatly elevated per capita extinction frequency occurred during the last million years of the Capitanian (260–259 Ma). Contrary to prevailing opinion, the end-Capitanian event did not preferentially eliminate large, morphologically complex species in the families Schwagerinidae and Neoschwagerinidae, because most species in those families were already extinct. Rather, 69 percent of the species eliminated at the end of the Capitanian were small, morphologically conservative representatives of the Ozawainellidae, Schubertellidae and Staffellidae. ...... The end-Capitanian extinction pulse might reflect environmental deterioration from the combined effects of global cooling, Emeishan effusive volcanism and sea-level lowstand.

==THE OLDEST RECORD OF A BORING FORAMINIFER==
 
 
[[Image:Lethaia_Cover.gif‎|left|80px|]]<font size="2">
 
The bioeroding foraminifer ''Troglotella incrustans'' Wernli and Fookes (''Bolletino della Societa Paleontologica Italiana ''31, 1992, 95), is widely reported from Bajocian?, and Oxfordian to Lower Cenomanian (with a Late Jurassic acme) shallow-water limestones of the Tethyan realm. A single specimen of a boring foraminifer, assigned to ''T. incrustans'', has now been observed from the Lower Permian (Sakmarian) Community Pit Formation of the Doña Ana Mountains, New Mexico, USA. Surviving the end-Permian mass extinction, T. incrustans might be a Lazarus taxon that persisted in refuges. This finding represents the oldest record of a foraminifer exhibiting an euendolithic way of life. Boring foraminifera have not been previously recorded from strata older than the Jurassic. Boring traces of potentially foraminiferan origin, however, have been already reported from the Lower Carboniferous (?Ordovician).

We describe the occurrence of basal (‘primitive’) foraminifera and gromiids (a distinct taxon related to the foraminifera) in different bathyal habitats of the Håkon Mosby Mud Volcano (HMMV, Barents Sea). ...... The number of basal foraminiferal and gromiid morphospecies varied considerably from site to site. It was relatively high north of the volcano (42 morphospecies in 4 samples) and in the ‘warm centre’ (28 morphospecies in 2 samples), somewhat lower southwest of the volcano (at least 13 morphospecies in 2 samples) and in the siboglinid field (14 morphospecies in three samples), and substantially reduced in the bacterial mat area (5 morphospecies in 6 samples). ...... Saccamminid sp. 5, by far the most common species in our samples, belongs to a ‘lamp-like’ morphotype that is widely distributed in the oceans. The wall structure, and the presence of what appears to be an internal partition across the base of the neck, is reminiscent of some komokiaceans.

[[Image:GeologicaCarpathica_front.jpg‎‎|left|80px|]]<font size="2">
 
The paper deals with benthic foraminifera occurring with the scleractinian corals in the Jurassic biohermal and peribiohermal coral-bearing limestones of the Vrsatec area (Czorsztyn Succession, Slovak Pieniny Klippen Belt). The coral community is dominated by branching forms of the genus ''Thecosmilia''. Co-occurring abundant benthic foraminifera belong to the species ''Rumanolina seiboldi'', ''R. elevata'', ''Paalzowella turbinella'' and ''Troglotella incrustans''. The coral-bearing limestones were initially assigned to the Oxfordian on the basis of the microfacies analyses and bivalve and scleractinian faunas. In recent papers they are assigned to the Bajocian on the basis of ammonites found in the neptunic dykes and stratigraphic superimposition criteria. However, the stratigraphic distribution of the majority of the identified foraminifera indicates that like most scleractinian coral taxa they are not known earlier than in the Late Jurassic. The Late Jurassic age of these coral-bearing limestones is also suggested by an encrusting microproblematic organism ''Iberopora bodeuri''.

Protists are key players in microbial communities, yet our understanding of their role in ecosystem functioning is seriously impeded by difficulties in identification of protistan species and their quantification. Current microscopy-based methods used for determining the abundance of protists are tedious and often show a low taxonomic resolution. Recent development of next-generation sequencing technologies offered a very powerful tool for studying the richness of protistan communities. Still, the relationship between abundance of species and number of sequences remains subjected to various technical and biological biases. Here, we test the impact of some of these biological biases on sequence abundance of SSU rRNA gene in foraminifera.  ......

==DEEP RELATIONSHIPS OF RHIZARIA REVEALED BY PHYLOGENOMICS==
 
 
[[Image:Molecular_Phylogenetics_and_Evolution.gif‎‎|left|80px|]]<font size="2">
 
Rhizaria is one of the six supergroups of eukaryotes, which comprise the majority of amoeboid and skeleton-building protists living in freshwater and marine ecosystems. There is an overall lack of molecular data for the group and therefore the deep phylogeny of rhizarians is unresolved. Molecular data are particularly scarce for the clade of Retaria, which include two prominent groups of microfossils: foraminiferans and radiolarians. To fill this gap, we have produced and sequenced EST libraries for 14 rhizarian species including seven foraminiferans, ''Gromia'' and six taxa belonging to traditional Haeckel’s Radiolaria: Acantharea, Polycystinea, and Phaeodarea. ...... In view of our study, Haeckel’s Radiolaria appears as both, a polyphyletic and paraphyletic assemblage of independent groups that should be considered as separate lineages in protist classification.

==CLIMATE-DRIVEN RANGE EXTENSION OF ''Amphistegina''==
 
 
[[Image:PLoS_ONE.jpg‎|left|80px|]]<font size="2">
 
Species-range expansions are a predicted and realized consequence of global climate change. Climate warming and the poleward widening of the tropical belt have induced range shifts in a variety of marine and terrestrial species. Range expansions may have broad implications on native biota and ecosystem functioning as shifting species may perturb recipient communities. Larger symbiont-bearing foraminifera constitute ubiquitous and prominent components of shallow water ecosystems, and range shifts of these important protists are likely to trigger changes in ecosystem functioning. We have used historical and newly acquired occurrence records to compute current range shifts of ''Amphistegina'' spp., a larger symbiont-bearing foraminifera, along the eastern coastline of Africa and compare them to analogous range shifts currently observed in the Mediterranean Sea. ......

Differentiating cladogenesis from anagenesis, defined as evolution within a species, has generally been hampered by dating precision, insufficient fossil data, and difficulties in establishing a direct link between morphological changes detectable in the fossil record and biological species. Here we quantify the relative frequencies of cladogenesis and anagenesis for macroperforate planktic Foraminifera, which arguably have the most complete fossil record currently available, to address this question. Analyzing this record in light of molecular evidence, while taking into account the precision of fossil dating techniques, we estimate that the fraction of speciation events attributable to anagenesis is <19% during the Cenozoic era (last 65 Myr) and <10% during the Neogene period (last 23 Myr). Our central conclusion—that cladogenesis is the predominant mode by which new planktic Foraminifera taxa become established at macroevolutionary time scales—differs markedly from the conclusion reached in a recent study based solely on fossil data. These disparate findings demonstrate that interpretations of macroevolutionary dynamics in the fossil record can be fundamentally altered in light of genetic evidence.

==LIVING BENTHIC FORAMINIFERA FROM THE CAP-FERRET CANYON: A COMPARISON BETWEEN THE CANYON AXIS AND THE SURROUNDING AREAS==
 
 
[[Image:DeepSeaResearch_I_front.gif‎ |left|80px|]]<font size="2">
 
Living (Rose Bengal stained) benthic foraminiferal faunas were investigated at 13 deep-sea stations sampled in the Cap-Ferret Canyon area (NE Atlantic). One station (151 m) is located on the continental shelf close to the canyon head. All other stations are located along 2 bathymetric transects: 7 sites along the canyon axis with depths ranging from 300 to 3000 m and 5 stations along the adjacent flank with depths ranging from 300 m to 2000 m. ...... <br/>
 
'''Highlights'''
 
► Live benthic foraminifera were studied at 13 stations in the Cap-Ferret Canyon. ► Fauna from the canyon axis were compared with live communities from adjacent areas. ► Geochemical data (e.g. OM composition) were used to described faunal distributions. ► Density and diversity along the canyon axis are higher than on the adjacent flank. ► This canyon shows lower density but higher diverse and complex fauna than Cap-Breton.

==WESTERN PACIFIC THERMOCLINE STRUCTURE AND THE PACIFIC MARINE ITCZ DURING THE LGM==
 
 
[[Image:EarthPlanetarySciLetters_front.gif‎|left|80px|]]<font size="2">
 
Paleoclimate proxy evidence suggests a southward shift of the Intertropical Convergence Zone (ITCZ) during times of Northern Hemisphere cooling, including the Last Glacial Maximum, 19–23 ka before present. However, evidence for movement over the Pacific has mainly been limited to precipitation reconstructions near the continents, and the position of the Pacific marine ITCZ is less well constrained. In this study, we address this problem by taking advantage of the fact that the upper ocean density structure reflects the overlying wind field. We reconstruct changes in the upper ocean density structure during the LGM using oxygen isotope measurements on the planktonic foraminifera ''G. ruber'' and ''G. tumida'' in a transect of sediment cores from the Western Tropical Pacific. The data suggests a ridge in the thermocline just north of the present-day ITCZ persists for at least part of the LGM, and a structure in the Southern Hemisphere that differs from today. The reconstructed structure is consistent with that produced in a General Circulation Model with both a Northern and Southern Hemisphere ITCZ.

==DEFINING PAST ECOLOGICAL STATUS AND ''in situ'' REFERENCE CONDITIONS USING BENTHIC FORAMINIFERA ==
 
 
<font size="2">
 
Characterizing marine water bodies and defining ecological status, both present and past (pre-impacted), has become an important task for EU's Member States and their associates during the last decade due to the implementation of the Water Framework Directive (WFD). However, none of the methods used to define Ecological Quality Status (EcoQS) are able to accurately define the status for both the present-day and reference conditions at a given site (i.e., ''in situ''). Recent studies have revealed a significant correlation between the diversity of living (stained) fossilizable benthic foraminifera (protists) and associated environmental parameters (e.g., dissolved oxygen concentration). The present study takes this relationship a step further by applying methods used to define present-day EcoQS on fossil benthic foraminiferal assemblages and, thereby, defining past EcoQS (PaleoEcoQS). ......

==LATE CRETACEOUS FORAMINIFERA FROM THE RIO DEL REY BASIN, SW CAMEROON ==
 
 
<font size="2">
 
Campanian–Maastrichtian marine sediments outcrop in five genetically linked sedimentary basins along the West African coast in the Gulf of Guinea, from the Douala Basin in Cameroon to the Anambra Basin in Nigeria. These sediments in the more centrally located Rio del Rey Basin have been the least studied. Therefore, the geologic history of this region has merely been speculative. The Rio del Rey Basin like the adjacent Niger Delta is producing hydrocarbon from the offshore Tertiary sedimentary interval in which all studies have been focused, neglecting the onshore Cretaceous sediments. Outcrops in the basin are rare, small and highly weathered. Samples from some of these sediments have yielded a few Planktonic and dominantly benthonic foraminiferal assemblages. ......

==THE RASC AND CASC PROGRAMS FOR RANKING, SCALING AND CORRELATION OF BIOSTRATIGRAPHIC EVENTS ==
 
 
<font size="2">
 
RASC is an acronym for RAnking and SCcaling of biostratigraphic events. Code of the RASC computer program was originally published in ''Computers & Geosciences''. During the past 30 years this program has been continuously maintained and updated. Its purpose is to combine biostratigraphic data from land-based sections or exploratory wells drilled in sedimentary basins to construct a regional biozonation that can be used for correlation between sections within a study area. Different methods of quantitative stratigraphy are briefly reviewed in this paper. Ranking is illustrated by application to a simple, artificial dataset. Scaling is explained as a refinement of ranking. Implications of sampling of stratigraphic sections are discussed in detail. Several examples of past successful large-scale RASC applications are given. These include results for well data from the Cenozoic North Sea basin, northwestern Atlantic margin and the Cretaceous seaway between Norway and Greenland. Paleoceanographic interpretations of RASC biozonations supplemented by analysis of variance and correlations between wells are exemplified as well. History of program development is summarized in an Appendix.

==THE FORAMINIFERA FROM THE BAZARUTO ARCHIPELAGO (MOZAMBIQUE)==
 
 
[[Image:NeuesJahrbuch_front.jpeg‎|left|80px|]]<font size="2">
 
The Bazaruto Archipelago in the western Indian Ocean is home to a diverse reef biota and a notable tourist attraction along the coast of Mozambique. Analyses of shallow-water reefal and lagoonal sediments from Bazaruto Island reveal two diverse assemblages of benthic foraminifera. The assemblages occupy three major environments and sedimentary regimes and are indicative of reef, channel and lagoon facies. Species richness, Fisher a analyses, assemblage composition, and percentage abundances of larger-symbiont-bearing foraminifera are mirrored in the cluster analyses. ...... Thus, the autochthonous benthic assemblages may preserve the original community structure and sufficient environmental information to be useful indicators for paleoecological studies.

==GLOBAL BIOGEOGRAPHIC DISTRIBUTION OF MORPHOSPECIES OF LIVING BENTHIC FORAMINIFERA==
 
 
[[Image:JMicro_front.gif|left|80px|]]<font size="2">
 
Previous studies have investigated regional distribution but this is the first attempt to investigate the global biogeographical distribution of individual morphospecies of living/stained smaller benthic foraminifera. From 8032 samples collected between 1952 and 2011 data have been gathered on the relative abundance of >120 species in five major environments ranging from marsh to deep sea. There is a spectrum of six groups of species with abundance ranging from very high (Group 1) to extremely low (Group 6). ......  Individual species are shown to occupy a range of environments with very few being confined to a single environment (usually either marsh or deep sea). Some species occur in several oceans while others are confined to just one. There is no correlation between species abundance and being either widely or narrowly distributed. ...... Patterns of biogeography have application to ecology, palaeoecology and taxonomy.

==1ST EXAMPLE WHERE THE MORPHOGLOCIAL VARIABILITY IN A MORPHOSPECIES EXCEEDS ITS rDNA GENETIC VARIABILITY==
 
 
[[Image:Paleobiology_cover.jpg‎|left|80px|]]<font size="2">
 
Previous genetic studies of extant planktonic foraminifera have provided evidence that the traditional, strictly morphological definition of species in these organisms underestimates their biodiversity. Here, we report the first case where this pattern is reversed. The modern (sub)tropical species plexus ''Globigerinoides sacculifer'' is characterized by large morphological variability, which has led to the proliferation of taxonomic names attributed to morphological end-members within the plexus. In order to clarify the taxonomic status of its morphotypes and to investigate the genetic connectivity among its currently partly disjunct (sub)tropical populations, we carried out a global survey of two ribosomal RNA regions (SSU and ITS-1) in all recent morphotypes of the plexus collected throughout (sub)tropical surface waters of the global ocean. ...... This is the first example in planktonic foraminifera where the morphological variability in a morphospecies exceeds its rDNA genetic variability. Such evidence for inconsistent scaling of morphological and genetic diversity in planktonic foraminifera could complicate the interpretation of evolutionary patterns in their fossil record.

==CALCIUM CARBONATE PRESERVATION VS. CLIMATE CHANGE OVER THE LAST 2400 YRS IN THE FRAM STRAIT ==
 
 
[[Image:Marine_Micropaleontology_Front.gif‎ |left|80px|]]<font size="2">
 
We present a high-resolution study of planktic foraminiferal distribution patterns in a deep sea core from the eastern Fram Strait (position 78° 55′ N; 06° 46′ E; water depth 1497 m). The sediment core is located below Atlantic water masses flowing into the Arctic Ocean and spans the last 2400 years. The investigation is based on planktic foraminiferal species distribution, stable isotopes, and sedimentological data. The mean shell weight of ''Neogloboquadrina pachyderma'', %fragmentation, organic and inorganic carbon content and the presence of benthic organic linings were also investigated as an indication of preservation changes. ...... <br/>

==TOWARDS RADIOCARBON DATING OF SINGLE FORAMINIFERA WITH A GAS ION SOURCE==
 
 
<font size="2">
 
Carbonate shells from foraminifera are often analysed for radiocarbon to determine the age of deep-sea sediments or to assess radiocarbon reservoir ages. However, a single foraminiferal test typically contains only a few micrograms of carbon, while most laboratories require more than 100 μg for radiocarbon dating with an accelerator mass spectrometry (AMS) system. The collection of the required amount of foraminifera for a single analyses is therefore time consuming and not always possible. Here, we present a convenient method to measure the radiocarbon content of foraminifera using an AMS system fitted with a gas ion source. ......

==SYMBIONT 'BLEACHING' IN PLANKTIC FORAMINIFERA DURING MIDDLE EOCENE CLIMATIC OPTIMUM==
 
 
[[Image:Geology_cover.gif‎|left|80px|]]<font size="2">
 
Many genera of modern planktic foraminifera are adapted to nutrient-poor (oligotrophic) surface waters by hosting photosynthetic symbionts, but it is unknown how they will respond to future changes in ocean temperature and acidity. Here we show that ca. 40 Ma, some fossil photosymbiont-bearing planktic foraminifera were temporarily 'bleached' of their symbionts coincident with transient global warming during the Middle Eocene Climatic Optimum (MECO).  ...... Our findings show that host-photosymbiont interactions are not constant through geological time, with implications for both the evolution of trophic strategies in marine plankton and the reliability of geochemical proxy records generated from symbiont-bearing planktic foraminifera.

[[Image:Marine_Micropaleontology_Front.gif‎ |left|80px|]]<font size="2">
 
An analysis of multispiral growth in Eocene nummulitids was performed. The ontogeny of some multispiral specimens was reconstructed, quantified and modelled, and the occurrence of multispiral growth in the different ''Nummulites'' and ''Assilina'' species has been reviewed. The results showed that all larger species display multispiral growth. ...... The gigantic sizes of 5 to 15 cm reached by ''Nummulites'' are produced mainly by the increase in growth rate provided by multispiral growth, and only secondarily by an increase in longevity that is thought to be of less than 6 years. The current view of larger foraminifera as slow growing, long-living, extreme K-strategists is questioned and discussed.

==DISCOVERY OF ORDOVICIAN ''Bathysiphon'' - TEST STRUCTURE AND HABITAT OF A 'LIVING FOSSIL'==
 
 
<font size="2">
 
The giant, agglutinated foraminiferan ''Bathysiphon'' Sars, previously Triassic–Recent, occurs in much older sedimentary rock (Early Ordovician, late early Tremadocian) of Avalonia....... A felt-like, agglutinated test, a lumen packed with spherical structures (probable stercomata) and the domal ends of some specimens are consistent with modern ''Bathysiphon''. This report is the first time that cytoplasmic activity and stercomata formation have been used to refer fossil protists to a modern group. ''Bathysiphon'' differs from the Cambrian foraminiferan ''Platysolenites'' Pander, which has an open lumen without stercomata, but support a comparable, sediment deposit-feeding niche. ''Bathysiphon'' is truly a ‘living fossil’, with a mode of test construction, cytoplasmic activity that formed stercomata and a niche unchanged for almost 500 million years. Foraminiferans have not been found prior to the Cambrian Period, and the Early Cambrian appearance of agglutinated foraminiferans is part of the radiation of Phanerozoic communities.

==BENTHIC FORAMINIFERA AS PROXIES OF POLLUTION: THE CASE OF GUANABARA BAY==
 
 
<font size="2">
 
Due to economic importance of Guanabara Bay, a multidisciplinary approach was adopted to investigate 88 surficial sediment samples in order to use the benthic foraminifera as indicators for the characterization of environmental variations. ...... <br/>
 
'''Highlights'''
 
► We carried out geochemical and foraminiferal analyses on sediments of Guanabara Bay. ► Geochemical data show high concentration of heavy metals in the northern region. ► Foraminifera result affected differently by pollutants. ► The taxon ''Buliminella elegantissima'' correlates with anthropogenic pollutants. ► Data highlights the presence of sterile sediments not previously reported in the bay.
