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 ...

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 ...

Environmental and taxonomic controls of carbon and oxygen stable isotope composition in Sphagnum across broad climatic and geographic ranges

Luca Bragazza, Mariusz Lamentowicz, Bjorn Jozef Maria Robroek

Rain-fed peatlands are dominated by peat mosses (Sphagnum sp.), which for their growth depend on nutrients, water and CO2 uptake from the atmosphere. As the isotopic composition of carbon (C-12(,)13) and oxygen (O-16(,)18) of these Sphagnum mosses are affe ...

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 ...

Unveiling exceptional Baltic bog ecohydrology, autogenic succession and climate change during the last 2000 years in CE Europe using replicate cores, multi-proxy data and functional traits of testate amoebae

Vincent Eric Jules Jassey, Mariusz Lamentowicz

We present the results of high-resolution, multi-proxy palaeoecological investigations of two parallel peat cores from the Baltic raised bog Mechacz Wielki in NE Poland. We aim to evaluate the role of regional climate and autogenic processes of the raised ...

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. ...

Freeze-thaw cycles simultaneously decrease peatland photosynthetic carbon uptake and ecosystem respiration

Alexandre Buttler, Constant Signarbieux, Vincent Eric Jules Jassey, Mariusz Lamentowicz, Bjorn Jozef Maria Robroek, Robert Thomas Edmund Mills, Maaike Louise Hofsommer

Decreasing snow cover in winter resulting from climate warming increases the incidence of freeze-thaw cycles (FTCs) in many ecosystems, including peatlands. As peatland ecosystems form a globally significant long-term carbon storage, understanding the effe ...
