Does species richness and abundance of saproxylic beetles differ between old near-natural and old managed forest in south-eastern Norway?
Norseng, Charlotte (Master thesis, 2016-08-31)Humans have altered almost all forests on earth through the need for forest resources. Several scientific papers show that forestry is a threat to the biodiversity and that many forest species will go extinct unless drastic ... -
Ectoparasite (Ceratophyllus vagabundus vagabundus) infestations reduce hatching success in precocial birds (Branta leucopsis) nesting in the High Arctic
Wetherbee, Ross (Master thesis, 2016-08-11)Arctic terrestrial ecosystems are ideal systems to study host-parasite interactions because they are sensitive and have fewer confounding interactions than lower latitudes. Since the Arctic is experiencing rapid climate ... -
Herbivorous insect diversity in boreal forest : a comparison between old near-natural forest and old managed forest in south-eastern Norway
Jensen, Helene Lind (Master thesis, 2016-09-01)Forestry has changed the forest structure and modified the associated ecosystems throughout time. With increasing extraction of forest resources in the future, there is a risk that most of the natural forests in Norway ... -
Interaction between Bombus terrestris and honeybees in red clover fields reduces abundance of other bumblebees and red clover yield
Müller, Helene Totland (Master thesis, 2016-11-17)Pollinator dependent crops have increased by 300% the last 50 years. At the same time many pollinator species are declining, including honeybees and bumblebees. Red clover is one of the crops dependent on bees for seed ...
