Article
Full-text available
Temperature and bioavailable energy control the distribution of life on Earth, and interact with each other due to the dependency of biological energy requirements on temperature. Here we analyze how temperature-energy interactions structure sediment microbial communities in two hydrothermally active areas of Guaymas Basin. Sites from one area expe...
Article
Deep, hot, and more alive than we thought Marine sediments represent a massive microbial ecosystem, but we still do not fully understand what factors shape and limit life underneath the seafloor. Analyzing samples from a subduction zone off the coast of Japan, Heuer et al. found that microbial life, in particular bacterial vegetative cells, decreas...

Previous studies have shown that microbially produced methane can be a dominant carbon source of lacustrine sedimentary macrofauna in eutrophic lakes, most likely through grazing on methane-oxidizing bacteria. Here we investigate the contributions of different carbon sources to macrofaunal biomass across five lakes in central Switzerland that range...
Article
Full-text available
Significance The majority of the seafloor is bioturbated by macrofauna and most organic carbon mineralization in marine sediments is performed by microorganisms inhabiting bioturbated sediment. However, little is known about how sediment macrofauna influence the community structure of these microorganisms. We show that microbial community compositi...

Full-text available
Even though human-induced eutrophication has severely impacted temperate lake ecosystems over the last centuries, the effects on total organic carbon (TOC) burial and mineralization are not well understood. We study these effects based on sedimentary records from the last 180 years in five Swiss lakes that differ in trophic state. We compare change...

Abstract The study investigates the in-situ strength of sediments across a plate boundary décollement using drilling parameters recorded when a 1180-m-deep borehole was established during International Ocean Discovery Program (IODP) Expedition 370, Temperature-Limit of the Deep Biosphere off Muroto (T-Limit). Information of the in-situ strength of...

Article
Subsurface sediments are among the largest, but also among the least understood ecosystems on Earth. However, novel analytical methods are contributing to constrain uncertainties regarding this unique environment. Here, the microbial community in subsurface sediments was investigated along a transect through the Benguela upwelling system from the o...

International Ocean Discovery Program (IODP) Expedition 370 aimed to explore the limits of life in the deep subseafloor biosphere at a location where temperature increases with depth at an intermediate rate and exceeds the known temperature maximum of microbial life (~120°C) at the sediment/basement interface ~1.2 km below the seafloor. Drilling Si...

Sediments across the Namibian continental margin feature a strong microbial activity gradient at their surface. This is reflected in ammonium concentrations of <10 μM in oligotrophic abyssal plain sediments near the South Atlantic Gyre (SAG) compared to ammonium concentrations of >700 μM in upwelling areas near the coast. Here we address changes in...
Data
Fig. S1. Pairwise comparison/correlation plot of 16S rRNA and bacterial amoA gene identities of cultivated AOB species. amoA genes and corresponding 16S rRNA genes of the same species of AOB were retrieved from GenBank (Benson et al., 2010) and JGI's IMG (Markowitz et al., 2006). The gene pair for a given AOB was compared with gene pairs of all oth...

Project
Understand the short- and long-term fate of organic carbon in lake sediments by integrating knowledge on environmental history with sedimentology, geochemistry, microbiology, and macrofaunal ecology. We hereby investigate lakes in central Switzerland that differ in trophic histories and investigate how anthropogenic activities - from the last interglacial until today - have affected the sedimentary carbon cycle.
Project
Biodiversity in Afrotropical forests is declining dramatically due to deforestation and intensified bushmeat trade. At the same time there is an increased frequency of outbreaks of emerging infectious diseases (EID) that have a natural reservoir in wild small mammals. The effect of biodiversity changes on the risk of spillover of these EID to humans is not yet clear. Higher biodiversity may reduce transmission rates in the small mammal community or may facilitate it. Biodiversity changes may also be associated with changes in human behaviour that affect contact rates with wildlife. BIODIV-AFREID will explore these relations in different forest sites in DR Congo and Côte d'Ivoire. We will investigate a range of viral pathogens but with a focus on three contrasting EID that are of major concerns: Monkeypoxvirus, Ebola virus and Coronavirus. We will : - Describe the biodiversity of small mammal communities in selected sites. - Study the presence and prevalence of the viruses in these communities. - Test hypotheses about dilution and amplification effects. - Test hypotheses about the ecological and anthropological conditions that facilitate spillover to humans. This project is funded by the EU-Biodiversa programs.
