Quantitative Evaluation of Bathymetric LiDAR Sensors and Acquisition Approaches in Lærdal River in Norway
(Peer reviewed; Journal article, 2023)The development of bathymetric LiDAR technology has contributed significantly to both the quality and quantity of river bathymetry data. Although several bathymetric LiDAR sensors are available today, studies that evaluate ... -
Development of a Real‑Time PCR Method for the Detection of European and Siberian Subtypes of Tick‑Borne Encephalitis Virus
(Peer reviewed; Journal article, 2023)The tick-borne encephalitis virus (TBEV) is transmitted to humans through tick bites. In recent years, the appearance of the Siberian subtype of TBEV in Ixodes ricinus in Finland, together with deaths from the normally ... -
New insights into the molecular phylogeny, biogeographical history, and diversification of Amblyomma ticks (Acari: Ixodidae) based on mitogenomes and nuclear sequences
(Peer reviewed; Journal article, 2024)Background: Amblyomma is the third most diversified genus of Ixodidae that is distributed across the Indomalayan, Afrotropical, Australasian (IAA), Nearctic and Neotropical biogeographic ecoregions, reaching in the Neotropic ... -
New insights into the systematics of the afrotropical Amblyomma marmoreum complex (Acari: Ixodidae) and the genome of a novel Rickettsia africae strain using morphological and metagenomic approaches
(Peer reviewed; Journal article, 2024)The Amblyomma marmoreum complex includes afrotropical species, such as Amblyomma sparsum, a three-host tick that parasitizes reptiles, birds, and mammals, and is a recognized vector of Ehrlichia ruminantium. However, the ... -
The role of familial conflict in home range settlement and fitness of a solitary mammal
(Peer reviewed; Journal article, 2023)Familial conflict, including parent–offspring conflict (POC) and sibling competition (SC), occurs when an individual maximizes its access to a limiting resource at the expense of a related individual. The role of familial ... -
Are nonsocial species more social than we think? Seasonal patterns in sociality in a solitary terrestrial carnivore
(Peer reviewed; Journal article, 2024)Animal sociality, the extent and manner in which conspecifics associate with each other, ultimately affects an individual's survival and reproductive success. It is shaped by the spatiotemporal configuration and composition ... -
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 ...
