Saharan dust deposition of nutrients and trace metals is crucial to microbes in the Mediterranean Sea. Here, we tested the response of microbial and viral communities to simulated dust deposition under present and future conditions of temperature and pH. Overall, the effect of the deposition was dependent on the initial microbial assemblage, and future conditions will intensify microbial responses. We observed effects on trophic interactions, cascading all the way down to viral processes.

Wind blowing over the ocean creates waves that, by increasing the level of turbulence, promote gas exchange at the air–water interface. In this study, for the first time, we measured enhanced gas exchanges by wind-induced waves at the surface of a large lake. We adapted an ocean-based model to account for the effect of surface waves on gas exchange in lakes. We finally show that intense wind events with surface waves contribute disproportionately to the annual CO2 gas flux in a large lake.

Simultaneous in situ measurements of (dry and wet) atmospheric deposition and biogeochemical stocks and fluxes in the sunlit waters of the open Mediterranean Sea revealed complex physical and biological processes occurring within the mixed layer. Nitrogen (N) budgets were computed to compare the sources and sinks of N in the mixed layer. The transitory effect observed after a wet dust deposition impacted the microbial food web down to the deep chlorophyll maximum.

Our study shows that the impact of dust deposition on primary production depends on the initial composition and metabolic state of the tested community and is constrained by the amount of nutrients added, to sustain both the fast response of heterotrophic prokaryotes and the delayed one of phytoplankton. Under future environmental conditions, heterotrophic metabolism will be more impacted than primary production, therefore reducing the capacity of surface waters to sequester anthropogenic CO2.

The circulation patterns in the confluence of the North Atlantic subtropical and tropical gyres delimited by the Cape Verde Front were examined during a field cruise in summer 2017. The collected hydrographic data, O2 and inorganic nutrients along the perimeter of a closed box embracing the Cape Verde Frontal Zone allowed for the independent estimation of the transport of these properties.

We present an ecological model called SPEAD wherein various phytoplankton compete for nutrients. Phytoplankton in SPEAD are characterized by two continuously distributed traits: optimal temperature and nutrient half-saturation. Trait diversity is sustained by allowing the traits to mutate at each generation. We show that SPEAD agrees well with a more classical discrete model for only a fraction of the cost. We also identify realistic values for the mutation rates to be used in future models.

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.

Residence times of particulate metals derived from aerosol deposition in the Sea Surface Microlayer of the Mediterranean Sea ranged from a couple of minutes (e.g., for Fe) to a few hours (e.g., for Cu). Microbial activity seems to play an important role in in this process and in the concentration and distribution of metals between diferent water layers.

Phytoplankton are an essential component of the marine food web and earth's carbon cycle. We use observations, ecological theory and a unique trait-based ecosystem model to explain controls on patterns of marine phytoplankton biodiversity. We find that different dimensions of diversity (size classes, biogeochemical functional groups, thermal norms) are controlled by a disparate combination of mechanisms. This may explain why previous studies of phytoplankton diversity had conflicting results.

Calcifying marine algae (coccolithophores) are key to oceanic biogeochemical processes, such as calcium carbonate production and export. We compile a global database of calcium carbonate production from field samples (n = 2756), alongside primary production rates and coccolithophore abundance. Basic statistical analysis highlights global distribution, average surface and integrated rates, patterns with depth and the importance of considering cell-normalised rates as a simple physiological index.

Marine diatoms are responsible for roughly 40 % of modern ocean primary production and contribute disproportionately to the drawdown of atmospheric carbon dioxide through the export of organic carbon into the deep sea and sediments. Over the past 40 Myr their rise to ecological prominence and consequential decline of coccolithophores is linked to the silicon to phosphorus weathering ratio, which controls the oceanic nutrient inventories and hence the competitive ability of diatoms.

Short summary
Diatoms are the dominant primary producers of the most productive and best fishing areas of the modern ocean, the coastal upwelling systems. This turns them into important contributors to the biological pump and climate change. To help untangle their response to warming climate, we compare the worldwide diatom sedimentary abundance (SDA) to environmental variables and find that the capacity of diatoms to take up silicic acid sets an upper limit on global export production in these ocean regions.

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.

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.

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.

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.
Here we present a DNA-based study of airborne archaea, show seasonal dynamics, and discuss anthropogenic influences on the diversity, composition, and abundances of airborne archaea.

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.

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

The microbial communities of up to 2.3 km depth of Precambrian crystalline bedrock fractures share features with serpenization-driven microbial communities in alkaline springs and subsurface aquifers. This study suggests that phylotypes belonging to Burkholderiales and Clostridia are possible "keystone microbial species" in Outokumpu deep biosphere. 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.

Short summary
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.
The effect of inorganic nutrients on planktonic assemblages has been traditionally assessed by...
