Invasion by Fallopia spp. in a French upland region is related to anthropogenic disturbances

Within Europe, mountain ecosystems are generally less invaded by exotic plant species than are lowland areas. This pattern is commonly attributed to climatic harshness, which limits invasive species presence, and higher propagule pressure and rates of dist ...

On the role of human mobility in the spread of cholera epidemics: towards an epidemiological movement ecology

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Lorenzo Righetto

We investigate the role of human mobility as a driver for long-range spreading of cholera infections, which otherwise primarily propagate through hydrologically controlled ecological corridors. We rely on a recent mechanistic, field-data validated, spatial ...

Polyploidy and invasion success: trait trade-offs in native and introduced cytotypes of two Asteraceae species

Alexandre Buttler, François Gillet, Aurélie Thébault

Invasion success is favoured by the introduction of pre-adapted genotypes. In addition, novel pressures in the introduced range may lead to phenotypic changes related to fitness or competitive ability of introduced plants. Polyploidy appears to be over-rep ...

Animal dispersal modelling: handling landscape features and related animal choices

Séverine Vuilleumier Varisco, Richard Metzger

Animal dispersal in a fragmented landscape depends on the complex interaction between landscape structure and animal behavior. To better understand how individuals disperse, it is important to explicitly represent the properties of organisms and the landsc ...
