==MOLECULAR PHYLOGENY OF ELPHIDIIDAE==

[[Image:Marine_Micropaleontology_Front.gif|left|80px|]]<font size="2">
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''.  ......

==SANTONIAN-CAMPANIAN PLANKTONIC FORAMINIFERA SPECIES DEPTH ECOLOGY AND PALEOCEANOGRAPHIC INFERENCES==

[[Image:Marine_Micropaleontology_Front.gif|left|80px|]]<font size="2">
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''. Additional results from Shatsky Rise (Ocean Drilling Program Leg 198, Hole 1210B) and Exmouth Plateau (ODP Leg 122, Hole 762C) provide geographic control on species habitat preferences and paleoceanographic context. ......

==DO FORAMINIFERA MIRROR DIVERSITY AND DISTRIBUTION PATTERNS OF MACROBENTHIC FAUNA IN AN ARCTIC FJORD?==

[[Image:Marine_Micropaleontology_Front.gif|left|80px|]]<font size="2">
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.

==HYPERSALINE BENTHIC FORAMINIFERA FROM EASTERN RED SEA: THEIR USEFULNESS IN SEA-LEVEL RECONSTRUCTION==

[[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.

==DISTRIBUTION OF BENTHIC FORAMINIFERS OF THE BASQUE SHELF==

<font size="2">
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. ......

==BIOSTRATIGRAPHY OF THE UPPER ALBIAN-UPPER CENOMANIAN OF THE TATRA MASSIF, CARPATHIANS==

[[Image:Acta Geologica Polonica front.jpg‎ ‎‎|left|80px|]]<font size="2">
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.

==ENVIRONMENTAL CHANGES DURING THE PETM IN SPITSBERGEN==

<font size="2">
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 ROLE OF FORAMINIFERA IN THE BENTHIC NITROGEN CYCLE OF THE PERUVIAN OMZ==

[[Image:Biogeosciences_front.jpg‎ ‎‎|left|80px|]]<font size="2">
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. ......

==A GIANT FORAMINIFER THAT CONVERGES TO THE FEEDING STRATEGY OF CARNIVOROUS SPONGES==

<font size="2">
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.

==FORAMINIFERAL INFLUENCES ON MICROFABRICS OF MICROBIALITES==

[[Image:PNAS_front.gif‎ |left|80px|]]<font size="2">
...... 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==

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. ......

==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).

==BASAL FORAMINIFERA AND GROMIIDS AT THE HÅKON-MOSBY MUD VOLCANO (BARENTS SEA SLOPE)==

<font size="2">
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.

<font size="2">
A new benthic foraminifer is described as ''Siphodinarella costata'' n. gen., n. sp. from Coniacian shallow-water platform-interior carbonates of Slovenia and Croatia. The new foraminifer is found in skeletal wackestone in association with small benthic foraminifera, thaumatoporellaceans, and calcimicrobes (''Decastronema'', ''Girvanella''-type tubes). The existence of an internal siphon in ''Siphodinarella'' n. gen. is interpreted as an entosolenian tube and discussed in terms of its generic and suprageneric importance.

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''.

==CAN ABUNDANCE OF PROTISTS BE INFERRED FROM SEQUENCE DATA==

[[Image:PLoS_ONE.jpg‎|left|80px|]]<font size="2">
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. ......

==CLADOGENESIS IN MACROEVOLUTION BY INTEGRATING FOSSIL AND MOLECULAR EVIDENCE==

[[Image:PNAS_front.gif‎ |left|80px|]]<font size="2">
Assessing the extent to which population subdivision during cladogenesis is necessary for long-term phenotypic evolution is of fundamental importance in a broad range of biological disciplines. 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.

==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.

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.

[[Image:Marine_Micropaleontology_Front.gif‎ |left|80px|]]<font size="2">
In addition to Oceanic Anoxic Event 2 (OAE2), other perturbations of the carbon cycle occurred during the Cenomanian and Turonian, of which the Middle Cenomanian Event (MCE) is the most prominent one. In palaeoecological publications, however, this event is strongly underrepresented in contrast to the well-studied OAE2. In order to fill this gap, we have studied Early Cenomanian to Late Turonian calcareous nannofossil and benthic foraminiferal assemblages of Ocean Drilling Program Site 1260 at Demerara Rise (western equatorial North Atlantic), in order to decipher biotic changes throughout this interval and especially across the MCE. ...... <br/>
'''Highlights'''
► Quantitative nannofossil data for the Middle Cenomanian Event (MCE) are presented. ► Long-lasting change of nannofossil- and benthic foraminiferal communities observed. ► The MCE is characterised by the onset of intensified water-column stratification. ► The MCE shows less speciations/extinctions than Oceanic Anoxic Event 2 (OAE2).

==BURDIGALIAN INFILL OF THE PUCHKIRCHEN TROUGH (NORTH ALPINE FORELAND BASIN, CENTRAL PARATETHYS)==

<font size="2">
To improve the prediction of gas and oil in strata along the tectonically imbricated southern margin of the Puchkirchen Trough (North Alpine Foreland Basin, Central Paratethys), a better understanding of facies distribution and stratigraphic control of the basin is essential. The present study provides bio- and chemofacies analyses and a biostratigraphic evaluation for the pelitic Hall Formation from the borehole Hochburg 1 in the central part of the Puchkirchen Trough. A statistical evaluation of benthic foraminiferal assemblages together with geochemical proxy records (TOC, sulfur, hydrogen index, δ<sup>13</sup>C<sub>TOC</sub>, δ<sup>15</sup>N<sub>TN</sub>) reveals a succession of early Burdigalian depositional environments. ...... <br/>
'''Highlights'''
► Combination of foraminiferal assemblages, geochemical proxies, seismic images. ► Hall Formation reveals succession of early Burdigalian depositional environments. ► Documentation of final sedimentary infill of the Puchkirchen Trough. ► Three 3rd-order sequences that correspond to global sequences Bur 1-3. ► Eustatic sea-level rather than tectonics controls Burdigalian deposition.

==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.
