Do individual differences in use of cover habitat affect red deer`s (Cervus elaphus) probability of being shot by hunters?
(Master thesis, 2014-08-19)The purpose of this study was to test if red deer (Cervus elaphus) habitat use affects their risk of being shot by hunters. I compared habitat use of 20 GPS-marked red deer that survived the hunting season with 20 individuals ... -
Do nitrogen-fixing legumes affect soil nutrient levels, plant growth or community properties of an alpine ecosystem?
(Master thesis, 2011-04-27)In this master thesis I examine how two N-fixing legume species, Astragalus alpinus L. and Oxytropis lapponica (Wahlenb.) Gay, affect different aspects of an alpine ecosystem in two sites situated along a gradient in ... -
Dobbeltpredasjon i et heterogent landskap : er det forskjeller i risikohabitat for hjort og rådyr?
(Master thesis, 2013-08-06)Uttrykket ”fryktens landskap” ble innført som en visuell modell for å forklare hvordan frykt kunne endre byttedyrs atferd og arealbruk for å redusere risikoen for å bli drept når predatorer er tilstede. Ulike habitater ... -
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 ... -
Does supplementary feeding of arctic fox (Vulpes lagopus) in Norway boost reproductive success?
(Master thesis, 2016-08-31)Ekstra fôring er eitt av fleire bevaringstiltak som har blitt brukt for å auke dyrs levedyktigheit. Supplerande fôring har hatt ulikt resultat basert på dyrs åtferd, intensitet og tilpassing av tiltak. Fjellrev er i Noreg ... -
Does the solitary bee Andrena lapponica show sex-specific responses to habitat change?
(Master thesis, 2017)Aim: Land use alterations are a serious challenge for solitary bees. This is especially so for specialized bees that rely on a single plant species when collecting pollen for their larvae. Moreover, the sex ratio within ... -
Does UV-discharge from high voltage power lines affect wild reindeers’ area use?
(Master thesis, 2015-11-05)Human activities and infrastructure continue to increase in northern regions, and in Scandinavia, the progressive development of wind and hydroelectric power, cabins, roads, and power lines is in conflict with the conservation ... -
