Habitat connectivity affects specialist species richness more than generalists in veteran trees
Sverdrup-Thygeson, Anne; Skarpaas, Olav; Blumentrath, Stefan; Birkemoe, Tone; Evju, Marianne (Journal article; Peer reviewed, 2017)Intensified human land use continues to increase habitat loss and fragmentation, and leads to a homogenization of biodiversity. Specialized species with narrow niches seem to be declining more rapidly than generalist ... -
