Food web structure and energy flux dynamics, but not taxonomic richness, influence microbial ecosystem functions in a Sphagnum-dominated peatland

Alexandre Buttler, Edward Mitchell, Vincent Eric Jules Jassey

Soil microbial communities are vital for multiple ecosystem processes and services. In particular, soil microbial food webs are key determinants of soil biodiversity, functioning and stability. Unclear, however, is how struc-tural features of food webs, su ...

21 000 birds in 4.5 h: efficient large‐scale seabird detection with machine learning

Devis Tuia, Benjamin Alexander Kellenberger

We address the task of automatically detecting and counting seabirds in unmanned aerial vehicle (UAV) imagery using deep convolutional neural networks (CNNs). Our study area, the coast of West Africa, harbours significant breeding colonies of terns and gul ...

Viral Transfer and Inactivation through Zooplankton Trophic Interactions

Tamar Kohn, Virginie Bachmann, Xavier Fernandez Cassi, Margot Ninon Lauren Olive

Waterborne viruses are responsible for numerous diseases and are abundant in aquatic systems. Understanding the fate of viruses in natural systems has important implications for human health. This research quantifies the uptake of bacteriophage T4 and the ...

Ecological implications of gene regulation by TfoX and TfoY among diverse Vibrio species

Melanie Blokesch, Candice Stoudmann, Noémie Matthey, Lisa Christina Metzger, Esther Jeanne Collas

Bacteria of the genus Vibrio are common members of aquatic environments where they compete with other prokaryotes and defend themselves against grazing predators. A macromolecular protein complex called the type VI secretion system (T6SS) is used for both ...

Light availability impacts structure and function of phototrophic stream biofilms across domains and trophic levels

Tom Ian Battin

Phototrophic biofilms are ubiquitous in freshwater and marine environments where they are critical for biogeochemical cycling, food webs and in industrial applications. In streams, phototrophic biofilms dominate benthic microbial life and harbour an immens ...

An ecotoxicological view on neurotoxicity assessment

Wolfgang Schulz

The numbers of potential neurotoxicants in the environment are raising and pose a great risk for humans and the environment. Currently neurotoxicity assessment is mostly performed to predict and prevent harm to human populations. Despite all the efforts in ...

Increasing temperature and decreasing specific leaf area amplify centipede predation impact on Collembola

Mathieu Raymond Santonja

Collembola is an abundant group of soil organisms playing a major role on litter decomposition process and nutrient cycling in forest ecosystems. Habitat structure strongly influences Collembola assemblages as plant litter physical characteristics and quan ...

A generalized definition of reactivity for ecological systems and the problem of transient species dynamics

Andrea Rinaldo, Lorenzo Mari, Marino Gatto

Perturbations to an ecosystem's steady state can trigger transient responses of great ecological relevance. Asymptotic stability determines whether a generic perturbation will fade out in the long run, but falls short of characterizing the dynamics imme ...

Application of remote sensing for the optimization of in-situ sampling for monitoring of phytoplankton abundance in a large lake

Alfred Johny Wüest, Damien Bouffard, Isabel Blanca Sophie Kiefer

Directives and legislations worldwide aim at representatively and continuously monitoring the ecological status of surface waters. In many countries, chlorophyll-a concentrations (CHL) are used as an indicator of phytoplankton abundance and the trophic lev ...

Mixtures of Chemical Pollutants at European Legislation Safety Concentrations: How Safe Are They?

Kristin Schirmer

The risk posed by complex chemical mixtures in the environment to wildlife and humans is increasingly debated, but has been rarely tested under environmentally relevant scenarios. To address this issue, two mixtures of 14 or 19 substances of concern (pesti ...
