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 ...

PEERJ INC2020

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 ...

WILEY2019

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

2018

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 ...

Pergamon-Elsevier Science Ltd2017

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. ...

From Environmental Sequences to Morphology: Observation and Characterisation of a Paulinellid Testate Amoeba (Micropyxidiella edaphonis gen. nov. sp. nov. Euglyphida, Paulinellidae) from Soil using Fluorescent in situ Hybridization

Enrique Lara, Sonia Estelle Tarnawski

High microbial diversity is revealed by environmental DNA surveys. However, nothing is known about the morphology and function of these potentially new organisms. In the course of an environmental soil diversity study, we found for the first time environme ...

Elsevier2015

An unexpected role for mixotrophs in the response of peatland carbon cycling to climate warming

Alexandre Buttler, Edward Mitchell, Luca Bragazza, Constant Signarbieux, Vincent Eric Jules Jassey, Bjorn Jozef Maria Robroek, Robert Thomas Edmund Mills, Enrique Lara, Bertrand Fournier

Mixotrophic protists are increasingly recognized for their significant contribution to carbon (C) cycling. As phototrophs they contribute to photosynthetic C fixation, whilst as predators of decomposers, they indirectly influence organic matter decompositi ...

Nature Publishing Group2015

Functional traits as a new approach for interpreting testate amoeba palaeo-records in peatlands and assessing the causes and consequences of past changes in species composition

Edward Mitchell, Vincent Eric Jules Jassey, Enrique Lara, Bertrand Fournier

Subfossil remains of various groups of organisms preserved in peat and sediment archives are commonly used to infer past environmental changes using transfer functions based on species composition. However, the changes in community structure can also be ex ...
