Contrasted propensity for waterborne and airborne dispersal between two closely related semi-aquatic spider species
Dispersal abilities are important to support metapopulation functioning and species distributions, yet it is rarely accounted for in conservation. Here, we compared the propensity for dispersal between the two fishing spiders present in Europe: the widespread habitat-generalist Dolomedes fimbriatus...

Dispersal abilities are important to support metapopulation functioning and species distributions, yet it is rarely accounted for in conservation.

We experimentally tested for airborne and waterborne dispersal using first instar juveniles sampled in nursery webs, and older juveniles.
