Motorway as a barrier to dispersal of the threatened dragonfly Sympetrum depressiusculum (Odonata: Libellulidae): Consequence of mortality or crossing avoidance?

Original language description

Infrastructure is one of the main causes of landscape fragmentation, which results in isolation and loss of populations. Although the negative effect of roads on insects is well documented, only a minority of studies has focused on roads in the context of barriers to dispersal. Flying species in particular have been neglected. We investigated the effect of a four-lane motorway as a barrier to the movement of an isolated population of the threatened dragonfl y Sympetrum depressiusculum in an agricultural landscape in Central Europe. Generalized additive models were used to assess the motorways effect on (i) the distribution of adult dragonfl ies in patches of terrestrial habitat surrounding their natal site, and (ii) individual fl ight behaviour (i.e. willingness or unwillingness to cross the motorway). Movement patterns of marked adults throughout the landscape were also investigated. During one season, signifi cantly fewer adults were found at patches located on the far side of the motorway, indica
