The effect of purging on sexually selected traits through antagonistic pleiotropy with survival
(Journal article; Peer reviewed, 2012)Sexually selected traits are expected to evolve to a point where their positive effect on reproductive success is counterbalanced by their negative effect on survival. At the genetic level, such a trade-off implies ... -
The effect of relatedness and pack size on territory overlap in African wild dogs
(Journal article; Peer reviewed, 2017)Background Spacing patterns mediate competitive interactions between conspecifics, ultimately increasing fitness. The degree of territorial overlap between neighbouring African wild dog (Lycaon pictus) packs varies greatly, ... -
The effect of repeated handling on telomere dynamics, body condition, and short-term survival in chicks of the Black-legged Kittiwake (Rissa tridactyla)
(Master thesis, 2017)In the present study, effects of investigator disturbance on chicks of the Black-legged Kittiwake were investigated by looking at telomere dynamics, growth, and short-term survival. An experiment group was exposed to a ... -
The Effect of Restoration Treatments on the Regeneration Pathway in Alpine Seed Plants
(Master thesis, 2011)Question: How does nutrient addition and seeding affect revegetation of seed plants, and are the effects differing among the stages of the regeneration pathway? Location: Two roads restored in 2002, located in Hjerkinn ... -
The effect of salmon protein hydrolysate on palatability for Atlantic salmon smolts
(Master thesis, 2024)Krav om bedre fiskevelferd og mer bærekraftig akvakultur gjør det nødvendig å finne nye og bedre fôrressurser. Når man vurderer nye ingredienser til fôr, kan valg av strategi ha stor innvirkning på tolkningen av kvaliteten ... -
The effect of socioeconomic factors on local community recognition of ecosystem services and support for biodiversity conservation: A case study of local communities in and around the Shwe Sett Taw Wildlife Sanctuary
(Master thesis, 2021)Protected Areas (PA) were established for conservation purposes in the past, later inevitably integrated into the local community residing in and around those areas for a certain period of time. One of the most important ... -
The effect of surveillance fishing on migrated distance of Atlantic salmon (Salmo salar L.) during the spawning period
(Master thesis, 2022)Atlantisk laks (Salmo salar L.) har blitt utsatt for et økende antall trusler de siste tiårene, noe som har ført til synkende bestander og til og med utryddelse av enkelte bestander. En av de største truslene er tilstedeværelse ... -
The effect of warming and foliar fungi on insect communities in the alpine tundra of Dovre, Trøndelag
(Master thesis, 2024)Den alpine tundraen er spesielt sårbar ovenfor effekten av global oppvarming sammenlignet med andre økosystemer. Noen av disse effektene, som migrering av planter oppover fjellet, har allerede blitt studert i flere år, men ... -
