Birds living on the edge : power-line corridors influence on avian communitites in Norwegian secondary coniferous forest
(Master thesis, 2012-11-16)Power-line corridor edges differ from other edge habitats by its long shape with a high amount of edge habitat compared to open fields, and the regular maintenance clearing the corridor for forest trees not allowing ... -
Dung beetle (Scarabaeidae, Scarabaeinae) communities in mountain rain forests (Tanzania): A biodiversity survey from Amani Nature Reserve and Udzungwa Mountain National Park
(Master thesis, 2015-07-30)The African dung beetles (Scarabaeidae, Scarabeinae) is the most generic and species rich of the global faunas. Dung beetles are good indicators of biodiversity and habitat disturbances. This study aimed to investigate ... -
