Testing foraging optimization models in brown bears: Time for a paradigm shift in nutritional ecology?
(Peer reviewed; Journal article, 2023)How organisms obtain energy to survive and reproduce is fundamental to ecology, yet researchers use theoretical concepts represented by simplified models to estimate diet and predict community interactions. Such simplistic ... -
Genetic diversity, gene flow, and landscape resistance in a pond-breeding amphibian in agricultural and natural forested landscapes in Norway
(Peer reviewed; Journal article, 2023)Genetic diversity is a key part of biodiversity, threatened by human activities that lead to loss of gene flow and reduction of effective population sizes. Gene flow is a result of both landscape connectivity and demographic ... -
Ecological signals of arctic plant-microbe associations are consistent across eDNA and vegetation surveys
(Peer reviewed; Journal article, 2023)Understanding how different taxa respond to abiotic characteristics of the environment is of key interest for understanding the assembly of communities. Yet, whether eDNA data will suffice to accurately capture environmental ... -
Wild Mountain reindeer Rangifer tarandus tarandus winter foraging: snow-free areas a key resource for feeding
(Peer reviewed; Journal article, 2023)In a landscape with patchily distributed forage resources, an animal’s distribution may reflect the distribution of the resources if the population is forage-limited in time or space. This may be particularly explicit in ... -
Do ingredient and nutrient intake reveal individual dietary specialization in an omnivorous carnivore, the brown bear?
(Peer reviewed; Journal article, 2024)Generalist populations often harbor individual dietary specialists. Whether using a narrower set of resources than the population (= specialization) affects specialists' nutrient intake remains underexplored. We evaluated ... -
“ClusterApp”: A Shiny R application to guide cluster studies based on GPS data
(Peer reviewed; Journal article, 2024)The rapid evolution of GPS devices, and therefore, collection of GPS data can be used to investigate a wide variety of topics in wildlife research. The combination of remotely collected GPS data with on-the- ground field ... -
Behavioural responses of brown bears to roads and hunting disturbance
(Peer reviewed; Journal article, 2024)Harvest regulations commonly attenuate the consequences of hunting on specific segments of a population. However, regulations may not protect individuals from nonlethal effects of hunting and their consequences remain ... -
Lone male loser? Effects of spatial isolation on male pairing success in the ortolan bunting Emberiza hortulana
(Peer reviewed; Journal article, 2023)In small, isolated or fragmented bird populations, past studies have shown that there can be a high proportion of unpaired males. Low male pairing success is suggested to be the result of female-biased natal dispersal and ... -
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 ... -
Hibernation ecology of brown bears in Sweden
(Chapter, 2023)Hibernation is an adaptive strategy to cope with unfavourable environmental conditions. Bears are the only large mammal that use this strategy during winter. They reduce their body temperature by several degrees and their ... -
Phylogenetic relationships of the Amblyomma cajennense complex (Acari: Ixodidae) at mitogenomic resolution
(Peer reviewed; Journal article, 2023)The genus Amblyomma is the third most diverse in the number of species within the Ixodidae, with practically half of its species distributed in the Americas, though there are also species occurring in Africa, Asia, and ... -
A camera trapping method for the targeted capture of Eurasian beaver (Castor fiber) tails for individual scale pattern recognition
(Peer reviewed; Journal article, 2023)Camera traps are commonly used to monitor and study wild animals in their natural habitat, with minimal disturbance. Several investigations have shown that the natural markings of animals for some species can be used for ... -
Individual recognition of Eurasian beavers (Castor fiber) by their tail patterns using a computer-assisted pattern-identification algorithm
(Peer reviewed; Journal article, 2024)Individual recognition of animals is an important aspect of ecological sciences. Photograph-based individual recognition options are of particular importance since these represent a non-invasive method to distinguish and ... -
A tale of tails: the use of Eurasian beaver (Castor fiber) tails for ageing and individual identification
(Peer reviewed; Journal article, 2023)With increasing technology and knowledge, the range of methods used to monitor wildlife is growing. As many invasive techniques have been shown to negatively impact study populations, the use of non-invasive methods is ... -
Annual ring width in the mediterranean-alpine shrub species Cytisus galianoi - dataset from long-term alpine ecosystem research in the Sierra Nevada, Spain (Ltaer-es)
(Journal article, 2023)This is a datapaper including microscopically measured data of annual ring widths from the Mediterranean-alpine shrub species Cytisus galianoi (Sierra Nevada, Spain). The dataset will be updated with future measurements. -
Patterns, timing, and environmental drivers of secondary growth in two physiologically distinct Mediterranean alpine shrub species
(Peer reviewed; Journal article, 2023)Alpine plants are particularly sensitive to climate change, and in the Mediterranean, less frequent winter cold and prolonged summer drought are expected to shift the growth patterns of species, altering their range and ... -
Patterns, timing, and environmental drivers of growth in two coexisting green-stemmed Mediterranean alpine shrubs species
(Peer reviewed; Journal article, 2023)The Mediterranean alpine is one of the most vulnerable ecosystems under future environmental change. Yet, patterns, timing and environmental controls of plant growth are poorly investigated. We aimed at an improved ... -
Geochemical landscapes as drivers of wildlife reproductive success: Insights from a high-Arctic ecosystem
(Peer reviewed; Journal article, 2023)The bioavailability of essential and non-essential elements in vegetation is expected to influence the performance of free-ranging terrestrial herbivores. However, attempts to relate the use of geochemical landscapes by ... -
Dataset from long-term air quality monitoring in the World Natural Heritage Geirangerfjord, Western Norway (AQM-G)
(Peer reviewed; Journal article, 2023)Here, we present a datapaper containing observational air quality and meteorological data related to our long-term air quality monitoring program at the UNESCO Natural World Heritage Site Geirangerfjord, Western Norway. ... -
Consistent imprints of elevation, soil temperature and moisture on plant and arthropod communities across two subarctic landscapes
(Peer reviewed; Journal article, 2023)1. Factors shaping arthropod and plant community structure at fine spatial scales are poorly understood. This includes microclimate, which likely plays a large role in shaping local community patterns, especially in ...
