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 ...

Soil protist function varies with elevation in the Swiss Alps

Nicolas Jean Philippe Guex, Edward Mitchell, Enrique Lara, Aline Buri

Protists are abundant and play key trophic functions in soil. Documenting how their trophic contributions vary across large environmental gradients is essential to understand and predict how biogeochemical cycles will be impacted by global changes. Here, u ...

Assessing the responses of Sphagnum micro-eukaryotes to climate changes using high throughput sequencing

Alexandre Buttler, Edward Mitchell, Vincent Eric Jules Jassey, Mariusz Lamentowicz, Enrique Lara

Current projections suggest that climate warming will be accompanied by more frequent and severe drought events. Peatlands store ca. one third of the world's soil organic carbon. Warming and drought may cause peatlands to become carbon sources through stim ...

Greater topoclimatic control of above‐ versus below‐ground communities

Nicolas Jean Philippe Guex, Loïc Pellissier, Edward Mitchell, Enrique Lara, Marco Pagni, Aline Buri

2020

Dispersal limitations and historical factors determine the biogeography of specialized terrestrial protists

Edward Mitchell, Luca Bragazza, Mariusz Lamentowicz, Enrique Lara, Bertrand Fournier

Recent studies show that soil eukaryotic diversity is immense and dominated by micro-organisms. However, it is unclear to what extent the processes that shape the distribution of diversity in plants and animals also apply to micro-organisms. Major diversif ...

Tipping point in plant-fungal interactions under severe drought causes abrupt rise in peatland ecosystem respiration

Alexandre Buttler, Pierre Rémi Mariotte, Edward Mitchell, Luca Bragazza, Vincent Eric Jules Jassey, Mariusz Lamentowicz, Bjorn Jozef Maria Robroek, Enrique Lara

Soil protistology rebooted: 30 fundamental questions to start with

Edward Mitchell, Vincent Eric Jules Jassey, Mariusz Lamentowicz, Enrique Lara, Thierry Jean Heger, Bertrand Fournier, Alexandre Jousset, Santosh Kumar

Protists are the most diverse eukaryotes. These microbes are keystone organisms of soil ecosystems and regulate essential processes of soil fertility such as nutrient cycling and plant growth. Despite this, protists have received little scientific attentio ...

Genetic Determinism vs. Phenotypic Plasticity in Protist Morphology

Edward Mitchell, Bjorn Jozef Maria Robroek, Mariusz Lamentowicz, Enrique Lara

Untangling the relationships between morphology and phylogeny is key to building a reliable taxonomy, but is especially challenging for protists, where the existence of cryptic or pseudocryptic species makes finding relevant discriminant traits difficult. ...
