Habitat fragmentation and vegetation structure impact gastrointestinal parasites of small mammalian hosts in Madagascar
Abstract Deleterious effects of habitat loss and fragmentation on biodiversity have been demonstrated in numerous taxa. Although parasites represent a large part of worldwide biodiversity, they are mostly neglected in this context. We investigated the effects of various anthropogenic environmental c...
