Dispersal of aquatic invertebrates by lesser black-backed gulls and white storks within and between inland habitats
: Waterbirds can transport aquatic invertebrates internally, contributing to metapopulation dynamics between aquatic habitats in a terrestrial matrix.

We investigated the invertebrates dispersed by endozoochory by the lesser black-backed gull Larus fuscus wintering in Andalusia, south-west Spain in 2016-2017, comparing seven sites interconnected by their movements, with different degrees of anthropogenization (three landfills, two saltpan complexes, a lake and a ricefield area).
