Human infrastructures can modify ecosystems, thereby affecting the occurrence and spatial distribution of organisms, as well as ecosystem functionality. Sustainable development requires the ability to predict responses of species to anthropogenic pressures. We investigated the large scale, long term effect of important human alterations of benthic habitats with an integrated approach combining ...

This is the first host record of Gymnophallus choledochus metacercariae infecting the polychaete Diopatra neapolitana in the Aveiro estuary (Portugal). The metacercariae were found unencysted, and their morphology is similar to that presented by metacercariae harbored by Nereis diversicolor and Cerastoderma edule, although they are larger in size. In D. neapolitana, the prevalence and mean inte...
