High-throughput sequencing of litter and moss eDNA reveals a positive correlation between the diversity of Apicomplexa and their invertebrate hosts across alpine habitats

In: Soil Biology & Biochemistry, 2020, vol. 147, no. art. 107837, p. 1-4

A high diversity of Apicomplexa was recently found in tropical soils presumably reflecting the diversity of their invertebrate hosts, but such patterns have not been explored in colder regions. We analysed the diversity of Apicomplexa and their potential metazoan hosts in litter and mosses collected in 11 different alpine habitats using an eDNA metabarcoding approach. The abundance and diversity...

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

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 diversification events in multicellular organisms have often been attributed to long‐term climatic and geological processes, but the impact of...

We are ready for faunistic surveys of bdelloid rotifers through DNA barcoding : the example of Sphagnum bogs of the Swiss Jura Mountains = Listos para revisiones faunísticas de rotíferos bdelloideos por DNA barcoding: el caso de las turberas de Sphagnum de las montañas del Jura suizo

The identification of biological diversity through DNA barcoding and metabarcoding of the organisms living in the field has the potential to revolutionise the way biological surveys and monitoring are performed. Yet, we still do not know if the current representativeness of the reference database of DNA sequence data is sufficient to allow such approaches. Here, we show that, at least for...

En garde! Redefinition of Nebela militaris (Arcellinida, Hyalospheniidae) and erection of Alabasta gen. nov.

Duckert, Clément ; Blandenier, Quentin ; Kupferschmid, Fanny A. L ; Kosakyan, Anush ; Mitchell, Edward A.D ; Lara, Enrique ; Singer, David

In: European Journal of Protistology, 2018, vol. 66, p. 156-165

Molecular data have considerably contributed to building the taxonomy of protists. Recently, the systematics of Hyalospheniidae (Amoebozoa; Tubulinea; Arcellinida) has been widely revised, with implications extending to ecological, biogeographical and evolutionary investigations. Certain taxa, however, still have an uncertain phylogenetic position, including the common and conspicuous species...

Eight species in the Nebela collaris complex : Nebela gimlii (Arcellinida,Hyalospheniidae), a new species described from a Swiss raised bog

Singer, David ; Kosakyan, Anush ; Pillonel, Amandine ; Mitchell, Edward A.D ; Lara, Enrique

In: European Journal of Protistology, 2015, vol. 51, no. 1, p. 79-85

We describe here a new species of sphagnicolous testate amoeba found abundantly in the forested part of the Le Cachot peatland (Jura Mountains, Neuchâtel, Switzerland) based on microscopical observations (LM, SEM). The new species, called Nebela gimlii was placed in a phylogenetic tree based on mitochondrial cytochrome oxidase sequences (COI), and branched robustly within the N....

Microbial eukaryote communities exhibit robust biogeographical patterns along a gradient of Patagonian and Antarctic lakes

Schiaffino, M. Romina ; Lara, Enrique ; Fernández, Leonardo D ; Balagué, Vanessa ; Singer, David ; Seppey, Christophe C. W ; Massana, Ramon ; Izaguirre, Irina

In: Environmental Microbiology, 2016, vol. 18, no. 12, p. 5249–5264

Microbial eukaryotes play important roles in aquatic ecosystem functioning. Unravelling their distribution patterns and biogeography provides important baseline information to infer the underlying mechanisms that regulate the biodiversity and complexity of ecosystems. We studied the distribution patterns and factors driving diversity gradients in microeukaryote communities (total, abundant,...
