Benthic organisms show aggregated distributions due to the spatial heterogeneity of niches or food. We analysed the distribution of Globobulimina turgida in the Gullmar Fjord, Sweden, with a data–model approach. The population densities did not show any underlying spatial structure but a random log-normal distribution. A temporal data series from the same site depicted two cohorts of samples with high or low densities, which represent hypoxic or well-ventilated conditions in the fjord.

The study addresses the potential of marine shell-forming organisms as proxy carriers for heavy metal contamination in the environment. The aim is to investigate if the incorporation of heavy metals is a direct function of their concentration in seawater. Culturing experiments with a metal mixture were carried out over a wide concentration range. Our results show shell-forming organisms to be natural archives that enable the determination of metals in polluted and pristine environments.

Recent observations from today’s oceans revealed that oxygen concentrations are decreasing, and oxygen minimum zones are expanding together with current climate change. With the aim of understanding past climatic events and their relationship with oxygen content, we looked at the fossils, called benthic foraminifera, preserved in the sediment archives from the Peruvian margin and quantified the bottom-water oxygen content for the last 22 000 years.

The study assessed the population dynamics of living planktic foraminifers on a weekly, seasonal, and interannual timescale off the coast of Puerto Rico to improve our understanding of short- and long-term variations. The results indicate a seasonal change of the faunal composition, and over the last decades. Lower standing stocks and lower stable carbon isotope values of foraminifers in shallow waters can be linked to the hurricane Sandy, which passed the Greater Antilles during autumn 2012.

Benthic foraminifera from the Bottsand coastal lagoon, western Baltic Sea, have been monitored annually since 2003 and accompanied by hydrographic measurements since 2012. Elphidium incertum, a stenohaline species of the Baltic deep water fauna, colonised the lagoon in 2016, most likely during a period of salinities > 19 units and average temperatures of 18 °C in early autumn. The high salinities probably triggered their germination from a propagule bank in the lagoonal bottom sediment.

Today’s oceans show distinct mid-depth oxygen minima while whole oceanic basins became transiently anoxic in the Mesozoic. To constrain past bottom-water oxygenation, we compared sediments from the Peruvian OMZ with the Cenomanian OAE 2 from Morocco. Corg accumulation rates in laminated OAE 2 sections match Holocene rates off Peru. Laminated deposits are found at oxygen levels of < 7µmol kg-1; crab burrows appear at 10µmol kg-1 today, both defining threshold values for palaeoreconstructions.

Planktonic gastropods (pteropods and heteropods) have been investigated in cores collected in the eastern Mediterranean along the Israeli coast in coral, pockmark, and channel areas. The sediment spans the last 5300 years. Our study reveals that neglecting the smaller fraction (> 63 µm) may result in a misinterpretation of the palaeoceanography. The presence of tropical and subtropical species reveals that the eastern Mediterranean acted as a refugium for these organisms.

We measured the oxygen isotopic composition of Late Jurassic chondrichthyan teeth (sharks, rays, chimaeras) from the Swiss Jura to get ecological information. The main finding is that the extinct shark Asteracanthus (Hybodontiformes) could inhabit reduced salinity areas, although previous studies on other European localities always resulted in a clear marine isotopic signal for this genus. We propose a mainly marine ecology coupled with excursions into areas of lower salinity in our study site.

The Ross Sea record of the Miocene Climatic Optimum (~16.9–14.7 Ma) and the Middle Miocene Climate Transition (~14.7–13.8 Ma) can provide critical insights into the Antarctic ocean–cryosphere system during an ancient time of extreme warmth and subsequent cooling. Benthic foraminifera inform us about water masses, currents, and glacial conditions in the Ross Sea, and planktic foram invaders can inform us of when warm waters melted the Antarctic Ice Sheet in the past.

Two species of giant, single-celled "trees” inhabit the seafloor in McMurdo Sound, Antarctica. These unicellular creatures are large enough to be seen and counted by scuba divers. We found that one of the tree species is widely spread, whereas the other inhabits only a small region on the western side of the sound. These types of unicellular trees have not been found elsewhere in the world ocean and are particularly vulnerable to the effects of climate change.

The Red Sea hosts exceptionally diverse marine environments despite elevated salinities. Distributions of benthic foraminifers were used to assess the ecological status of coral reef environments in the Ras Mohamed Nature Reserve, south Sinai. Sediment samples collected in mangrove, shallow-lagoon, and coral reef habitats yielded 95 foraminiferal species. Six species, five hosting algal symbionts, made up ~70 % of the specimens examined, indicating water quality suitable for reef accretion.

This was questioned and Malcolm Hart studied the material in Vienna, taking some to London for SEM imaging. Samples collected from Poland are compared to these images and the suggested planktic mode of life discussed. Foraminifera collected in Ogrodzieniec are glauconitic steinkerns with no test material present and none of the diagnostic features needed to determine "new" species.</p>

Acmes of agglutinated foraminifera correlate between different sections and can be used for paleoenvironmental analysis expressing inter-regional changes.

The study presents (1) a validation of a method which was previously published allowing us to recognize different Ammonia phylotypes (T1, T2 and T6) based only on their morphology and (2) a refined biogeographical distribution presented here supporting the putatively invasive character of phylotype T6. Results suggest that phylotype T6 is currently spreading out and supplanting autochthonous phylotypes T1 and T2 along the coastlines of the British Isles and northern France.

Morphologically similar benthic foraminifera taxa are difficult to separate, resulting in incorrect identifications, complications understanding species-specific ecological preferences, and flawed reconstructions of past environments. Here we provide descriptions and illustrated guidelines on how to separate some key Arctic–North Atlantic species to circumvent taxonomic confusion, improve understanding of ecological affinities, and work towards more accurate palaeoenvironmental reconstructions.

During the early Toarcian (Jurassic, 180 Ma) a hyperthermal event, the Jenkyns Event, occurred, affecting the oxygenation of the sea bottom. The integrated study of foraminiferal and ostracod assemblages with geochemical proxies allows us to interpret the incidence of this event in the Western Tethys, more exactly in the South Iberian Palaeomargin. Diminution of diversity, changes in abundance, and opportunist vs. specialist are coincident with the event.

The microfossils from a Cretaceous outcrop in southern Turkey are described and used to interpret the age of the rocks and their depositional setting and how sea level has changed. These results are compared both locally and regionally, identifying broad correspondence with regional sea level events. A new species of microfossil is described, confirming that many microfossils of Arabia are localised in their distribution.

The Mid-Brunhes Transition saw an enigmatic shift towards increased glacial temperature variations about 400 kyr ago. High-latitude Southern Ocean stratification may have been a causal factor, but little is known of the changes to the high-latitude Bering Sea. We generated benthic foraminiferal assemblage data and are the first to document a glacial decrease in episodic primary productivity since the Mid-Brunhes Transition, signifying possible reductions in sea ice summer stratification.

Short summary
The use of micropalaeontological samples from mudstone successions that have suffered de-watering and compaction means that subtle, lamina-thick, changes in assemblages may be lost when samples are processed that are 1–2 cm thick. As most micropalaeontological samples are often 2–5 cm thick, one must be then cautious of interpretations based on such short-duration changes. This work is part of an integrated study of the Christian Malford lagerstätten that has resulted in a number of papers.

Benthic foraminifera often colonize marine underwater vegetation in tropical regions. We studied these so-called epiphytic foraminifera in a shallow bay in the Bahamas. Here the foraminifera differed between types of vegetation, but sedimentological processes seem to be the main controller of the dead foraminifera in the sediment. This indicates that in carbonate platform regions, epiphytic foraminifera should only be used cautiously as direct indicators of past in situ marine vegetation.

Current climate and environmental changes strongly affect shallow marine and coastal areas like the Baltic Sea. The combination of foraminiferal geochemistry and environmental parameters demonstrates that in a highly variable setting like the Baltic Sea, it is possible to separate different environmental impacts on the foraminiferal assemblages and therefore use chemical factors to reconstruct how seawater temperature, salinity, and oxygen varied in the past and may vary in the future.

Benthic foraminifera from the Bottsand coastal lagoon, western Baltic Sea, have been monitored annually since 2003 and accompanied by hydrographic measurements since 2012. Elphidium incertum, a stenohaline species of the Baltic deep water fauna, colonised the lagoon in 2016, most likely during a period of salinities > 19 units and average temperatures of 18 °C in early autumn. The high salinities probably triggered their germination from a propagule bank in the lagoonal bottom sediment.

We carried out a morphometric study of late Paleocene orthophragminids from the Mawmluh Quarry section in the Shillong Plateau, India. We recorded the occurrence of two species of Orbitoclypeus, whereas the other typical Tethyan genera Discocyclina is absent. We also identified the associated benthic foraminifera and algae. Shallow benthic zones (SBZ) 3 and 4 have been recognized in the section. The timing of transition from shallow marine to continental deposition is commented on.

Shallow-water carbonate deposits rich in larger benthic foraminifera (LBF) are well-known from the Eocene of the Americas. However, there have been few recent LBF studies in this region. Here we present the LBF ranges from two previously unpublished sections from the Ocala limestone, Florida. The study indicates that the lower member of the Ocala limestone may be Bartonian rather than Priabonian in age, with implications for regional biostratigraphy.

This study constitutes an attempt to analyze the variations in foraminiferal assemblages using the morphogroup approach in the Late Devonian. Our results show that both methods of estimating morphotype percentages, the traditional counting and the cumulated area methods, provide similar results, are highly correlated with each other, and provide similar relationships with paleoenvironmental proxies.

Short summary
Ammonia beccarii was described from Rimini Beach in 1758. This taxon has often been mistaken with other species in the past. Recent studies assessed the biometry of Ammonia species and integrated it with genetic data but relied on a few large and dead specimens only. In a comprehensive approach, we assessed the whole living Ammonia assemblage near the type locality of A. beccarii and identified parameters which are robust and facilitate a secure species identification.
Ammonia beccarii was described from Rimini Beach in 1758. This taxon has often been mistaken...
