Metapopulation persistence and species spread in river networks

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari

River networks define ecological corridors characterised by unidirectional streamflow, which may impose downstream drift to aquatic organisms or affect their movement. Animals and plants manage to persist in riverine ecosystems, though, which in fact harbo ...

Morphological, hydrological, biogeochemical and ecological changes and challenges in river restoration – The Thur River case study

David Andrew Barry, Paolo Perona

River restoration can enhance river dynamics, environmental heterogeneity and biodiversity, but the underlying processes governing the dynamic changes need to be understood to ensure that restoration projects meet their goals, and adverse effects are preve ...

On species persistence-time distributions

Andrea Rinaldo, Enrico Bertuzzo, Amos Maritan, Lorenzo Mari, Samir Suweis

We present new theoretical and empirical results on the probability distributions of species persistence times in natural ecosystems. Persistence times, defined as the timespans occurring between species' colonization and local extinction in a given geogra ...

COI gene reveals size-dependent high dispersal and low intra-specific diversity in free-living terrestrial protists (Euglyphida; Assulina)

Enrique Lara

Aim Propagule size and ecological requirements are believed to be major factors influencing the passive dispersal of free-living terrestrial protists. We compared the colonization potential of three closely related testate amoeba species (Assulina muscoru ...

Modern comprehensive approach to monitor the morphodynamic evolution of a restored river corridor

Paolo Perona

River restoration has become a common measure to repair anthropogenically-induced alteration of fluvial ecosystems. The inherent complexity of ecohydrologic systems leads to limitations in understanding the response of such systems to restoration over time ...

Effects of Colonization Asymmetries on Metapopulation Persistence

Olivier Lévêque, Séverine Vuilleumier Varisco

Ocean currents, prevailing winds, and the hierarchical structures of river networks are known to create asymmetries in re-colonization between habitat patches. The impacts of such asymmetries on metapopulation persistence are seldom considered, especially ...

Effects of cognitives abilities on metapopulation connectivity

Séverine Vuilleumier Varisco

Connectivity among demes in a metapopulation depends on both the landscape's and the focal organism's properties (including its mobility and cognitive abilities). Using individual-based simulations, we contrast the consequences of three different cognitive ...
