    • Environmental filtering and phylogenetic clustering correlate with the distribution patterns of cryptic protist species 

      Singer, David; Kosakyan, Anush; Seppey, Christophe Victor W.; Pillonel, Amandine; Fernandez, Leonardo D; Fontaneto, Diego; Mitchell, Edward A.D.; Lara, Enrique (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-01-29)
      The community composition of any group of organisms should theoretically be determined by a combination of assembly processes including resource partitioning, competition, environmental filtering, and phylogenetic legacy. Environmental DNA studies have revealed a huge diversity of protists in all environments, raising questions about the ecological significance of such diversity and the degree to ...

    • Greater topoclimatic control of above‐ versus below‐ground communities 

      Mod, Heidi K.; Scherrer, Daniel; Di Cola, Valeria; Broennimann, Olivier; Blandenier, Quentin; Breiner, Frank T.; Buri, Aline; Goudet, Jérôme; Guex, Nicolas; Lara, Enrique; Mitchell, Edward A. D.; Niculita‐Hirzel, Hélène; Pagni, Marco; Pellissier, Loïc; Pinto‐Figueroa, Eric; Sanders, Ian R.; Schmidt, Benedikt R.; Seppey, Victor William Christophe; Singer, David; Ursenbacher, Sylvain; Yashiro, Erika; van der Meer, Jan R.; Guisan, Antoine (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-31)
      Assessing the degree to which climate explains the spatial distributions of different taxonomic and functional groups is essential for anticipating the effects of climate change on ecosystems. Most effort so far has focused on above-ground organisms, which offer only a partial view on the response of biodiversity to environmental gradients. Here including both above- and below-ground organisms, we ...

    • Niche Conservatism Drives the Elevational Diversity Gradient in Major Groups of Free-Living Soil Unicellular Eukaryotes 

      Fernández, Leonardo D.; Seppey, Victor William Christophe; Singer, David; Fournier, Bertrand; Tatti, Dylan; Mitchell, Edward A.D.; Lara, Enrique (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-30)
      Ancestral adaptations to tropical-like climates drive most multicellular biogeography and macroecology. Observational studies suggest that this niche conservatism could also be shaping unicellular biogeography and macroecology, although evidence is limited to Acidobacteria and testate amoebae. We tracked the phylogenetic signal of this niche conservatism in far related and functionally contrasted ...

    • Protist taxonomic and functional diversity in soil, freshwater and marine ecosystems 

      Singer, David; Seppey, Victor William Christophe; Lentendu, Guillaume; Dunthorn, Micah; Bass, David; Belbahri, Lassaad; Blandenier, Quentin; Debroas, Didier; de Groot, G. Arjen; de Vargas, Colomban; Domaizon, Isabelle; Duckert, Clément; Izaguirre, Irina; Koenig, Isabelle; Mataloni, Gabriela; Schiaffino, M. Romina; Mitchell, Edward A.D.; Geisen, Stefan; Lara, Enrique (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-19)
      Protists dominate eukaryotic diversity and play key functional roles in all ecosystems, particularly by catalyzing carbon and nutrient cycling. To date, however, a comparative analysis of their taxonomic and functional diversity that compares the major ecosystems on Earth (soil, freshwater and marine systems) is missing. Here, we present a comparison of protist diversity based on standardized high ...

    • Soil protist diversity in the Swiss western Alps is better predicted by topo-climatic than by edaphic variables 

      Seppey, Christophe Victor W.; Broennimann, Olivier; Buri, Aline; Yashiro, Erika; Pinto-Figueroa, Eric; Singer, David; Blandenier, Quentin; Mitchell, Edward A.D.; Niculita-Hirzel, Helene; Guisan, Antoine; Lara, Enrique (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11-01)
      <i>Aim</i> - Trends in spatial patterns of diversity in macroscopic organisms can be well predicted from correlative models, using topo‐climatic variables for plants and animals allowing inference over large scales. By contrast, diversity in soil microorganisms is generally considered as mostly driven by edaphic variables and, therefore, difficult to extrapolate on a large spatial scale based on ...
