Procambarus clarkii is currently recorded from 16 European territories. On top of being a
vector of crayfish plague, which is responsible for large-scale disappearance of native …

Negative interactions have been suggested as a major barrier for species arriving in a new
habitat. More recently, positive interactions drew attention from community assembly theory …

Biological invasions are one of the most important ecological disturbances that threaten
native biodiversity. An expected increase in the rate of species extinction will have major …

Non‐native species introductions affect freshwater communities by changing community
compositions, functional roles, trait occurrences and ecological niche spaces …

With accelerating rates of invasion being documented in many ecosystems, communities of
interacting invasive species are becoming increasingly common. Opposing theories predict …

The lesser Antilles archipelago in the Caribbean is known as a biodiversity hotspot, hosting
many endemic species. However, recent introduction of a highly invasive species, the …

When invasive species become integrated within a food web, they may have numerous
direct and indirect impacts on the native community by creating novel trophic links, and …

There is a long history of crayfish introductions in Europe and numbers keep increasing. In
Hungary, spiny-cheek crayfish Faxonius limosus, signal crayfish Pacifastacus leniusculus …

Abstract Knowledge on the trophic niche of animal species is important for understanding
their coexistence and hence animal diversity. Trophic niches have been shown to vary with …

Impacts of invasive signal crayfish Pacifastacus leniusculus on native species and
ecosystems are widely recognised, but mostly through small‐scale studies and laboratory …
