Spread of proliferative kidney disease in fish along stream networks: A spatial metacommunity framework

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Luca Carraro, Marino Gatto

Proliferative kidney disease (PKD) is a high-mortality pathology that critically affects freshwater salmonid populations. Infection is caused by the endoparasitic myxozoan Tetracapsuloides bryosalmonae, which exploits freshwater bryozoans as primary hosts. ...

Interacting populations in heterogeneous environments

Séverine Vuilleumier Varisco

To optimally manage a metapopulation, managers and conservation biologists can favor a type of habitat spatial distribution (e.g. aggregated or random). However, the spatial distribution that provides the highest habitat occupancy remains ambiguous and num ...

An exactly solvable coarse-grained model for species diversity

Andrea Rinaldo, Samir Suweis, Amos Maritan

We present novel analytical results concerning ecosystem species diversity that stem from a proposed coarse-grained neutral model based on birth-death processes. The relevance of the problem lies in the urgency for understanding and synthesizing both theor ...

On species persistence-time distributions

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

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 ...

How patch configuration affects the impact of disturbances on metapopulation persistence

Séverine Vuilleumier Varisco

Disturbances affect metapopulations directly through reductions in population size and indirectly through habitat modification. We consider how metapopulation persistence is affected by different disturbance regimes and the way in which disturbances spread ...

Effects of cognitives abilities on metapopulation connectivity

Séverine Vuilleumier Varisco, Nicolas Perrin

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 ...
