Does species richness and abundance of saproxylic beetles differ between old near-natural and old managed forest in south-eastern Norway?
(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 ... -
Effects of size and forest structure of old-growth forests on the species richness of saproxylic insects
(Master thesis, 2016-02-18)Many saproxylic insects are threatened by extinction, and a decline in the saproxylic species has been observed since the 1800s. The loss of areas of old-growth forest, fragmentation and the decline in volume of dead wood ... -
Species richness and abundance of saproxylic beetles in power-line corridors: effects of different management practices
(Master thesis, 2015-02-25)Beetles (Coleoptera) are a major component of forest biodiversity. Approximately 900 of the 3558 known beetle species in Norway are facultative or obligate saproxylic, that is, directly or indirectly dependent on dead wood. ... -
The significance of tree, site and landscape variables on eight saproxylic beetles in hollow oaks
(Master thesis, 2015-08-07)Fragmentation of habitats is a great threat to biodiversity. An especially vulnerable species group is saproxylic beetles. Many of these are associated with hollow oaks, which provide a unique and stable habitat. The number ...
