Allometric relationships in morphological traits associated with foraging, swimming ability, and predator defense reveal adaptations toward brackish and freshwater environments in the threespine stickleback
(Peer reviewed; Journal article, 2020)Freshwater colonization by threespine stickleback has led to divergence in morphology between ancestral marine and derived freshwater populations, making them ideal for studying natural selection on phenotypes. In an open ... -
Altitude, latitude, and climate zone as determinants of mountain hare (Lepus timidus) coat colour change
(Peer reviewed; Journal article, 2023)Local adaptation to annually changing environments has evolved in numerous spe-cies. Seasonal coat colour change is an adaptation that has evolved in multiple mam-mal and bird species occupying areas ... -
Barriers and bridges for sustaining functional habitat networks: A macroecological system analysis of wet grassland landscapes
(Peer reviewed; Journal article, 2022)This study aims at supporting the maintenance of representative functional habitat networks as green infrastructure for biodiversity conservation through transdisciplinary macroecological analyses of wet grassland landscapes ... -
Biogeographic position and body size jointly set lower thermal limits of wandering spiders
(Peer reviewed; Journal article, 2021)Most species encounter large variations in abiotic conditions along their distribution range. The physiological responses of most terrestrial ectotherms (such as insects and spiders) to clinal gradients of climate, and in ... -
Bottom-up rather than top-down mechanisms determine mesocarnivore interactions in Norway
(Peer reviewed; Journal article, 2024)Interactions among coexisting mesocarnivores can be influenced by different factors such as the presence of large carnivores, land-use, environmental productivity,or human disturbance. Disentangling the relative importance ... -
A brain and a head for a different habitat: Size variation in four morphs of Arctic charr (Salvelinus alpinus (L.)) in a deep oligotrophic lake
(Peer reviewed; Journal article, 2020)Adaptive radiation is the diversification of species to different ecological niches and has repeatedly occurred in different salmonid fish of postglacial lakes. In Lake Tinnsjøen, one of the largest and deepest lakes in ... -
Camera trap records of leucistic Eurasian badgers (Meles meles) in central Norway
(Peer reviewed; Journal article, 2021)Coat coloration plays an important role in communication, camouflage, and sexual selection in animals. Genetic mutations can lead to anomalous colorations such as melanism and leucism, where animals appear, respectively, ... -
The declining occurrence of moose (Alces alces) at the southernmost edge of its range raise conservation concerns
(Peer reviewed; Journal article, 2021)The border region between Austria, the Czech Republic, and Germany harbors the most south-western occurrence of moose in continental Europe. The population originated in Poland, where moose survived, immigrated from former ... -
Diversifying selection drives parallel evolution of gill raker number and body size along the speciation continuum of European whitefish
(Peer reviewed; Journal article, 2018)Adaptive radiation is the evolution of ecological and phenotypical diversity. It arises via ecological opportunity that promotes the exploration of underutilized or novel niches mediating specialization and reproductive ... -
Estimating effective survey duration in camera trap distance sampling surveys
(Peer reviewed; Journal article, 2023)Among other approaches, camera trap distance sampling (CTDS) is used to estimate animal abundance from unmarked populations. It was formulated for videos and observation distances are measured at predetermined ‘snapshot ... -
Genetic differences between wild and hatchery-bred brown trout (Salmo trutta L.) in single nucleotide polymorphisms linked to selective traits
(Journal article; Peer reviewed, 2017) -
Habitat segregation between brown bears and grey wolves in a human-dominated landscape
(Peer reviewed; Journal article, 2018) -
How do microtine rodent abundance, snow and landscape parameters influence pine marten Martes martes population dynamics?
(Peer reviewed; Journal article, 2024)The pine marten (Martes martes) occupies the northernmost extent of its distribution in Norway, where microtine rodents are an important food item. The relationship between microtine rodent abundance and pine marten ... -
Identifying and correcting spatial bias in opportunistic citizen science data for wild ungulates in Norway
(Peer reviewed; Journal article, 2021)Many publications make use of opportunistic data, such as citizen science observation data, to infer large-scale properties of species’ distributions. However, the few publications that use opportunistic citizen science ... -
Is the diet cyclic phase-dependent in boreal vole populations?
(Peer reviewed; Journal article, 2024)Herbivorous rodents in boreal, alpine and arctic ecosystems are renowned for their multi-annual population cycles. Researchers have hypothesised that these cycles may result from herbivore–plant interactions in various ... -
Predation of endangered Arctic foxes by Golden eagles: What do we know?
(Peer reviewed; Journal article, 2023)Dedicated conservation efforts spanning the past two decades have saved the Fennoscandian Arctic fox (Vulpes lagopus) population from local extinction, and ex-tensive resources continue to be invested in the species' ... -
Predator community and resource use jointly modulate the inducible defense response in body height of crucian carp
(Peer reviewed; Journal article, 2021)Phenotypic plasticity can be expressed as changes in body shape in response to environmental variability. Crucian carp (Carassius carassius), a widespread cyprinid, displays remarkable plasticity in body morphology and ... -
Scavenger community structure along an environmental gradient from boreal forest to alpine tundra in Scandinavia
(Peer reviewed; Journal article, 2020)Scavengers can have strong impacts on food webs, and awareness of their role in ecosystems has increased during the last decades. In our study, we used baited cam-era traps to quantify the structure of the winter scavenger ... -
Scavenging patterns of an inbred wolf population in a landscape with a pulse of human-provided carrion
(Peer reviewed; Journal article, 2023)Scavenging is an important part of food acquisition for many carnivore species that switch between scavenging and predation. In landscapes with anthropogenic impact, humans provide food that scavenging species can utilize. ... -
Shining a light on elusive lynx: Density estimation of three Eurasian lynx populations in Ukraine and Belarus
(Peer reviewed; Journal article, 2023)The Eurasian lynx is a large carnivore widely distributed across Eurasia. However, our understanding of population status is heterogeneous across their range, with some populations isolated that are at risk of reduced ...
