Beyond the patch: on landscape-explicit metapopulation dynamics

Climate change threatens biodiversity and species distribution all over the world at unprecedented rates. Human induced changes to landscape structure and habitat are redefining the relation between species and their environment. Understanding, characteriz ...

On the probabilistic nature of the species-area relation

Andrea Rinaldo, Andrea Giometto, Jonathan Giezendanner, Silvia Zaoli, Amos Maritan

The Species-Area Relation (SAR), which describes the increase in the number of species S with increasing area A, is under intense scrutiny in contemporary ecology, in particular to probe its reliability in predicting the number of species going extinct as ...

A minimalist model of extinction and range dynamics of virtual mountain species driven by warming temperatures

Andrea Rinaldo, Enrico Bertuzzo, Damiano Pasetto, Jonathan Giezendanner

A longstanding question in ecology concerns the prediction of the fate of mountain species under climate change, where climatic and geomorphic factors but also endogenous species characteristics are jointly expected to control species distributions. A sign ...

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 ...

Effects of Connectivity and Recurrent Local Disturbances on Community Structure and Population Density in Experimental Metacommunities

Andrea Rinaldo, Francesco Carrara, Florian Altermatt

Metacommunity theory poses that the occurrence and abundance of species is a product of local factors, including disturbance, and regional factors, like dispersal among patches. While metacommunity ideas have been broadly tested there is relatively little ...

A neutral metapopulation model of biodiversity in river networks

Andrea Rinaldo

In this paper, we develop a stochastic, discrete, structured meta population model to explore the dynamics and patterns of biodiversity of riparian vegetation. In the model, individual plants spread along a branched network via directional dispersal and un ...

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 ...

On biodiversity in river networks: A trade-off metapopulation model and comparative analysis

Andrea Rinaldo

A discrete, structured metapopulation model is coupled with the strictly hierarchical competition-colonization trade-off model, in which competitively superior species have lower fecundity rates and thus lower colonizing ability, to study the resulting bio ...

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 ...
