Contrasted propensity for waterborne and airborne dispersal between two closely related semi‐aquatic spider species
Abstract 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 fi...

Abstract 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. We estimated the propensity for short and long‐distance dispersal of airborne and waterborne behaviours, and we tested the difference between species with generalised linear mixed models.
