The avifaunal value of the Lofoten Islands in a World Heritage perspective
(NINA Rapport;201, Research report, 2006)This report describes the quality of the bird life in the Lofoten Islands, primarily assessed according to national and international criteria such as those outlined in the Norwegian Red List 1998 and by IUCN and BirdLife ... -
The beat of the mountain: a transdisciplinary rhythmanalysis of temporal landscapes
(Journal article; Peer reviewed, 2018)This article discusses how studying rhythms can help us better understand and manage spatiotemporal tensions in social-ecological landscapes, highlighting the potential of rhythmanalysis as a tool for crossing scientific ... -
The Brown bear as a translational model for sedentary lifestyle-related diseases
(Peer reviewed; Journal article, 2019)Sedentary lifestyle accelerates biological ageing, is a major risk factor for developing metabolic syndrome and is associated with cardiovascular disease, diabetes mellitus, kidney failure, sarcopenia and osteoporosis. ... -
The cost of anadromy: marine and freshwater mortality rates in anadromous Arctic char and brown trout in the Arctic region of Norway
(Peer reviewed; Journal article, 2019)It is hypothesized that in diadromous fish, migrations may occur because of differences in the availability of food in marine and freshwater habitats. The benefits of migration to sea may be increased growth opportunities ... -
The cost of migratory prey: seasonal changes in semi-domesticreindeer distribution influences breeding success of Eurasian lynx in northern Norway
(Peer reviewed; Journal article, 2016)Migratory prey is a widespread phenomenon that has implications for predator – prey interactions. By creating large temporal variation in resource availability between seasons it becomes challenging for carnivores to ... -
The devil is in the detail: non-additive and context-dependent plant population responses to increasing temperature and precipitation. Plant demography in a warmer & wetter climate
(Journal article; Peer reviewed, 2018)In climate‐change ecology, simplistic research approaches may yield unrealistically simplistic answers to often more complicated problems. In particular, the complexity of vegetation responses to global climate change begs ... -
