Heterogeneity among species and community dynamics – Norwegian bird communities as a case study
(Journal article; Peer reviewed, 2018)We have in this study analysed bird communities across Norway with a heterogeneous species abundance model, where dynamical parameters can vary among species. Similarity in community composition over time, used as a measure ... -

Hibernation and plasma lipids in free-ranging brown bears-implications for diabetes
(Peer reviewed; Journal article, 2023)Brown bears (Ursus arctos) prepare for winter by overeating and increasing adipose stores, before hibernating for up to six months without eating, drinking, and with minimal movement. In spring, the bears exit the den ... -
Hidden treasure of the Gobi: understanding how water limits range use of khulan in the Mongolian Gobi
(Peer reviewed; Journal article, 2020)Most large herbivores in arid landscapes need to drink which constrains their movements and makes them vulnerable to disturbance. Asiatic wild ass or khulan (Equus hemionus) were widespread and abundant throughout the arid ... -
High inter‐ and intraspecific niche overlap among three sympatrically breeding, closely related seabird species: Generalist foraging as an adaptation to a highly variable environment?
(Peer reviewed; Journal article, 2019)1. Ecological niche theory predicts sympatric species to show segregation in their spatio‐temporal habitat utilization or diet as a strategy to avoid competition. Similarly, within species individuals may specialize on ... -
High levels of multiple paternity in a spermcast mating
(Journal article, 2018)Multiple paternity is an important characteristic of the genetic mating system and common across a wide range of taxa. Multiple paternity can increase within-population genotypic diversity, allowing selection to act on ... -
High pathogenicity avian influenza (H5N1) in Northern Gannets (Morus bassanus): Global spread, clinical signs and demographic consequences
(Peer reviewed; Journal article, 2023)During 2021 and 2022 High Pathogenicity Avian Influenza (HPAI) killed thousands of wild birds across Europe and North America, suggesting a change in infection dynamics and a shift to new hosts, including seabirds. Northern ... -

High tolerance of a high-arctic willow and graminoid to simulated ice encasement
(Journal article; Peer reviewed, 2018)Climate change-induced snow thaw and subsequent accumulation of ice on the ground is a potential, major threat to snow-dominated ecosystems. While impacts of ground-ice on arctic wildlife are well explored, the impacts on ... -
High-resolution modeling of uplift landscapes can inform micrositing of wind turbines for soaring raptors
(Journal article, 2020)Collision risk of soaring birds is partly associated with updrafts to which they are attracted. To ident ify the risk-enhancinglandscape features, a micrositing tool was developed to model orographic and thermal updraft ... -
Higher leaf nitrogen content is linked to tighter stomatalregulation of transpiration and more efficient water use acrossdryland trees
(Peer reviewed; Journal article, 2022)The least-cost economic theory of photosynthesis shows that water and nitrogen are mutu-ally substitutable resources to achieve a given carbon gain. However, vegetation in the Sahelhas to cope with the dual challenge imposed ... -
Highways associated with expansion of boreal scavengers into the alpine tundra of Fennoscandia
(Peer reviewed; Journal article, 2020)1. Habitat fragmentation may affect species distributions through, for example, altered resource availability and shifts in species interactions. Fragmentation by roads has had negative impacts on Fennoscandian alpine ... -

The Historical Complexity of Tree Height Growth Dynamic Associated with Climate Change in Western North America
(Peer reviewed; Journal article, 2022)The effect of climate on tree growth has received increased interest in the context of climate change. However, most studies have been limited geographically and with respect to species. Here, sixteen tree species of western ... -
