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.

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.

The Baltic Sea is expected to experience a rapid drop in salinity and increases in acidity and warming in the next century. Calcifying mussels dominate Baltic Sea seafloor ecosystems yet are sensitive to changes in seawater chemistry. We combine laboratory experiments and a field study and show that a lack of calcium causes extremely slow growth rates in mussels at low salinities. Subsequently, climate change in the Baltic may have drastic ramifications for Baltic seafloor ecosystems.

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.

The distribution of mussel in estuaries is limited but the mechanisms are not well understood. We document for the first time that reduced Ca2+ concentration in the low saline, brackish Baltic Sea affects the ability of mussel larvae to calcify the first larval shell. As complete formation of the shell is a prerequisite for successful development, impaired calcification during this sensitive life stage can have detrimental effects on the species' ability to colonize habitats.

Detecting the 2.54 Ma onset of Pleistocene glaciations has in the tropical, abyssal oceans long been a problem. Using an assemblage turnover index (ATI), we show that the onset can be detected using benthic foraminifera. It is marked by an increase in mean benthic foraminiferal ATI, which reflects changes in the proportional abundance of phytodetritivores due to a change in nutrient flux. This was caused by repositioning of the ITCZ. Bottom current strength was also impacted.

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.

Here, we studied the effects of metabolism and growth temperature on 2H/1H fractionation between fatty acids and growth water (εFA/water) by Shewanella piezotolerans WP3. Our results show that the εFA/water values display considerable variations for cultures grown on different substrates. Combined with metabolic model analysis, our results indicate that the central metabolic pathways exert a fundamental effect on the hydrogen isotope composition of lipids in heterotrophs.

Bacterial communities in the soils of the Arctic region decompose soil organic matter to CO2 from a large carbon pool. The amount of CO2 released is likely to increase under future climate conditions. Here, we study how temperature sensitive the growth of soil bacterial communties is for 12 sampling sites in the sub to high Arctic. We show that the optimal growth temperature varies between 23 and 34 °C and is influenced by the summer temperature.

This study revealed the distinct distribution patterns of six key microbial functional genes and transcripts related to N2O sources and sinks in four estuaries spanning the Chinese coastline, which were significantly constrained by nitrogen and oxygen concentrations, salinity, temperature, and pH. The community structure of the nosZ clade II was distinctly different from those in the soil and marine OMZs. Denitrification may principally control the N2O emissions patterns across the estuaries.

We spectroscopically evaluated the gradients of dissolved C, N, S, Fe and Mn in a newly formed redox-stratified lake. The lake features an intermediate redox state between nitrogenous and euxinic conditions that encompasses vigorous open sulfur cycling fuelled by the reducible Fe and Mn stocks of the anoxic sediments. This results in substantial bottom water loads of dissolved iron and sulfate. Observations made in this ecosystem have relevance for deep-time paleoceanographic reconstructions.

Coccolithophores are important unicellular algae with a calcium carbonate covering that might be affected by ongoing changes in the ocean due to absorption of CO2, warming, and melting of glaciers. We used the southern Patagonian fjords as a natural laboratory, where chemical conditions are naturally highly variable. One variant of a widespread coccolithophore species can tolerate these conditions, suggesting it is highly adaptable, while others were excluded, suggesting they are less adaptable.

The bacteria carried by winds over the island of Sardinia in the Mediterranean Sea were collected, and their identities were investigated by reading DNA sequences. The sampling period was the factor that most determined the airborne species composition as its role was stronger than that of dust-carrying storms and of the geographical position of the sampling station. The bacteria found when the sampling was performed in September had more species variety than those collected in May.

Microbial processes of the methane cycle were studied in four lakes of the central part of the Yamal Peninsula in an area of continuous permafrost: two large, deep lakes and two small and shallow ones. It was found that only small, shallow lakes contributed significantly to the overall diffusive methane emissions from the water surface during the warm summer season. The water column of large, deep lakes on Yamal acted as a microbial filter preventing methane emissions into the atmosphere.

Amphistegina lobifera (Foraminifera) has colonized the Mediterranean through the Suez Canal, often forming thick sediments altering the invaded environments. Little is known about postmortem fate of its shells, so I investigated their turnover in the rhizosphere of the dominant Mediterranean seagrass. Most were bioeroded, likely by cyanobacteria and algae but not fungi occurring in the seagrass roots. Bioerosion may counterbalance accumulation of A. lobifera shells in the seabed substrate.

tidal zonationon the prokaryotic sediment communities of a pristine mangrove forest. We observed that the variability in environmental factors between tidal zones results in differences in structure, diversity, and the potential function of prokaryotic populations. This suggests that further work is needed in determining the role tidal microhabitat biodiversity has in mangroves.

The concentration of chlorophyll is commonly used as an indicator of the abundance of photosynthetic plankton (phytoplankton) in lakes and oceans. Our study investigates why a deep chlorophyll maximum, located near the bottom of the upper, illuminated layer develops in the Mediterranean Sea. We find that the acclimation of cells to low light is the main mechanism involved and that this deep maximum represents also a maximum in the biomass and carbon fixation activity of phytoplankton.

Coccolithophores are important calcifying phytoplankton with an overlooked life cycle. We compile a global dataset of marine coccolithophore abundance to investigate the environmental characteristics of each life cycle phase. We find that both phases contribute to coccolithophore abundance and that their different environmental preference increases coccolithophore habitat. Accounting for the life cycle of coccolithophores is thus crucial for understanding their ecology and biogeochemical impact.

In this work, three different endolithic microhabitats occurring in gypcrete rocks of the Atacama Desert are characterized, using both microscopy and molecular techniques, to show if the architecture of each microhabitat has an influence on the microbial communities inhabiting each of them.

Many natural environments differ in their range of salt concentration (salinity). We developed a metric for the number of water molecules in formation reactions of different proteins and found that it decreases between freshwater and marine systems and also in laboratory experiments with increasing salinity. These results demonstrate a new type of link between geochemical conditions and the chemical composition of microbial communities that can be useful for models of microbial adaptation.

Potential roles of polythionates as key sulfur cycle intermediates are less appreciated, apparently because, in most of the natural environments, they do not accumulate to easily detectable levels. Our exploration of the eastern Arabian Sea sediment horizons revealed microbe-mediated production and redox transformations of tetrathionate to be important modules of the in situ sulfur cycle, even as high biotic and abiotic reactivity of this polythionate keeps it hidden from geochemical detection.

Industrial-scale mining of deep-sea polymetallic nodules will remove nodules in large areas of the sea floor. We describe community composition of microbes associated with nodules of the Peru Basin. Our results show that nodules provide a unique ecological niche, playing an important role in shaping the diversity of the benthic deep-sea microbiome and potentially in element fluxes. We believe that our findings are highly relevant to expanding our knowledge of the impact associated with mining.

We show that soil pH is a key factor in selecting distinct phylotypes of methanotrophs in paddy soils. Type II methanotrophs dominated the methane oxidation in low-pH soils, while type I methanotrophs were more active in high-pH soils. This pH-based niche differentiation of active methanotrophs appeared to be independent of nitrogen fertilization, but the inhibition of type II methanotrophic rate in low-pH soils by the fertilization might aggravate the emission of methane from paddy soils.

Microbial community composition and diversity in freshwater habitats are much less studied compared to marine and soil communities. This study presents the first assessment of microbial communities of the Rajang River, the longest river in Malaysia, expanding our knowledge of microbial ecology in tropical regions. Areas surrounded by oil palm plantations showed the lowest diversity and other signs of anthropogenic impacts included the presence of CFB groups as well as probable algal blooms.

Permafrost temperatures increased substantially at a global scale, potentially altering microbial assemblages involved in carbon mobilization before permafrost thaws. We used Arctic Shelf submarine permafrost as a natural laboratory to investigate the microbial response to long-term permafrost warming. Our work shows that millennia after permafrost warming by > 10 °C, microbial community composition and population size reflect the paleoenvironment rather than a direct effect through warming.

Cold-water corals were found at active sites in Pompeia Province (Gulf of Cádiz). Since seeped fluids are harmful for the corals, we approached the environmental conditions that allow corals to colonize carbonates while seepage occurs. As a result, we propose that chemosynthetic microorganisms (i.e. sulfide-oxidizing bacteria and AOM-related microorganisms) play an important role in the colonization of the corals at these sites by feeding on the seeped fluids and avoiding coral damage.

The present study describes responses of picocyanobacteria (PCY) physiology to different environmental conditions. The cultures were grown under 64 combinations of temperature, irradiance in a photosynthetically active spectrum (PAR), and salinity. The results show that each strain of Baltic Synechococcus sp. behaves differently in respective environmental scenarios. The study develops the knowledge on bloom-forming PCY and reasons further research on the smallest size fraction of phytoplankton.

The effect of inorganic nutrients on planktonic assemblages has been traditionally assessed by looking at concentrations rather than fluxes of nutrient supply. However, in near-steady-state systems such as subtropical gyres, nitrate concentrations are kept close to the detection limit due to phytoplankton uptake. Our results, based on direct measurements of nitrate diffusive fluxes, support the key role of nitrate supply in controlling the structure of marine picoplankton communities.

Archaea as a third domain of life play an important role in soils and marine environments. Although archaea have been found in air as a part of the atmospheric bioaerosol, little is known about their atmospheric dynamics due to their low number and challenging analysis.

We report the distribution of major nano- and pico-plankton groups in the western tropical South Pacific. We found microbial community structure to be typical of highly stratified regions of the open ocean, with significant contributions to total biomass by picophytoeukaryotes, and N2 fixation playing a central role in regulating ecosystem processes. Our results also suggest a reduction in the importance of predation in regulating bacteria populations under nutrient-limited conditions.

Ongoing human impact transforms habitats into surfaces lacking higher vegetation. Here, biological soil crusts (BSCs) provide ecosystem services like soil creation and carbon uptake. To understand the functioning of these areas, we examined the physiological capability of early successional BSCs. We found features enabling BSCs to cope with varying climatic stresses. BSCs are important carbon fixers independent of the dominating organism. We provide baseline data for modeling carbon fluxes.

The soil microbial properties were investigated along altitudinal gradients in the Arctic. Systematic altitudinal shift in MCS resulting in high F / B ratios at the most elevated sites was observed. The changes in composition, size and activity of microbial communities were mainly controlled through the effect of vegetation on edaphic properties and by bedrock chemistry. The upward migration of vegetation due to global warming will likely diminish the spatial variability in microbial properties.

The n-alkane in litterfall and the microbial community in litter layer in different habitats of lowland subtropical rainforest were studied. We revealed that the plant vegetation of forest not only dominated the n-alkane input of habitats but also governed the diversity of microbial community of litter layer. In this study, we found that the habitat which had high n-alkane input induced a shift of relative abundance toward phylum of Actinobacteria and the growth of alkB gene contained bacteria.

Arctic, Antarctic and alpine biological soil crusts (BSCs) are formed by adhesion of soil particles to cyanobacteria. BSCs influence ecosystems services like soil erodibility and chemical cycles. In cold environments degradation rates are low and BSCs increase soil organic carbon through photosynthesis, whereby these soils are considered as CO2 sinks. This work provides a novel method to visualize BSCs with a focus on cyanobacteria and their contribution to soil organic carbon.

Why can biocrust moss survive and flourish in these habitats when stressed simultaneously by drought and sand burial? A field experiment was conducted to assess the combined effects of the two stressors on Bryum argenteum within biocrust. The two stressors did not exacerbate the single negative effects; their mutually antagonistic effect on the physiological vigor of B. argenteum was found, and it provided an opportunity for it to overcome the two co-occurring stressors in arid sandy ecosystems.

The major controls identified were organic matter availability, C / N, temperature, and O2 in the water column, revealing higher rates in warm, stratified, hypoxic seasons compared to colder, oxygenated seasons.

In this study we show increasing organic matter (OM) content on ferrihydrite surfaces enhances Fe reduction by the model Fe reducer S. oneidensis and a microbial consortia extracted from peat. Similarities in reduction rates between S. oneidensis and the consortia suggest electron shuttling dominates in OM-rich soils. Community profile analyses showed enrichment of fermenters with pure ferrihydrite, whereas OM–mineral complexes favored enrichment of Fe-reducing Desulfobacteria and Pelosinus sp.

We evaluated the bacterial composition and diversity of bamboo soils sampled at different elevations and incubated at different temperatures. Soil respiration was greater at higher elevation and temperature. Soil bacterial structure and diversity showed variable under different incubation times and temperatures. Increases in temperature increased soil respiration and consumption of soil soluble carbon and nitrogen, thus influencing the bacterial diversity and structure at different elevations.

Despite their permanently cold and dark characteristics, subglacial environments (glacier ice–sediment interface) are known to harbour active microbial communities. However, the role of microbial iron cycling in these environments is poorly understood. Here we show that subglacial sediments harbour active iron-reducing microorganisms, and they appear to be cold-adapted. These results may have important implications for global biogeochemical iron cycling and export to marine ecosystems.

Endoliths are a prominent bioerosive component of intertidal marine habitats, traditionally thought to be formed by a few cyanobacteria, algae and fungi. Using molecular techniques, however, we found that endoliths from Mona Island, Puerto Rico, were of high diversity, well beyond that reported in traditional studies. We also found evidence for substrate specialization, in that closely related cyanobacteria seem to have diversified to specialize recurrently to excavate various mineral substrates

Many of the keystone species belong to the rare biosphere with low abundance but a wide range of carbon substrates and a capacity for H2 oxidation.

Some benthic foraminifera can incorporate chloroplasts from microalgae. We investigated chloroplast functionality of two benthic foraminifera (Haynesina germanica & Ammonia tepida) exposed to different light levels. Only H. germanica was capable of using the kleptoplasts, showing net oxygen production. Chloroplast functionality time was longer in darkness (2 weeks) than at high light (1 week). Kleptoplasts are unlikely to be completely functional, thus requiring continuous chloroplast resupply.

We observed that phytoplankton biomass and growth rate (μ), microzooplankton grazing rate (m), and coupling (correlation) between the μ and m significantly varied between the summer and winter, and microzooplankton selectively grazed more on the larger-sized phytoplankton, and a low grazing impact on phytoplankton (m/μ < 50%) in the SSCS. The salient seasonal variations in μ and m, and their coupling were closely related to environmental variables under the influence of the East Asian monsoon.

Despite their global importance, redox reactions mediated by microorganisms are often crudely represented in biogeochemical models. We show that including the dynamics of microbial growth in such a model can cause sudden shifts between redox states in response to an environmental change. We identify the conditions required for these redox regime shifts, and predict that they are likely in the modern day sulfur and nitrogen cycles, and potentially the iron cycle in the ancient ocean.

We also compared the results with airborne archaea from Cape Verde and observe that the proportions of Euryarchaeota seem to be enhanced in coastal air compared to continental air.
