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 ... -
Climate influence on plant–pollinator interactions in the keystone species Vaccinium myrtillus
(Journal article; Peer reviewed, 2022)Climate change is altering the world's ecosystems through direct effects of climate warming and precipitation changes but also indirectly through changes in biotic interactions. For instance, climate-driven changes in plant ... -
“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 ... -
Couch potatoes do better: Delayed dispersal and territory size affect the duration of territory occupancy in a monogamous mammal
(Journal article; Peer reviewed, 2017)In territorial, socially monogamous species, the establishment and defense of a terri - tory are an important strategy to maximize individual fitness, but the factors responsi - ble for the duration of territory occupancy ... -
Directed endozoochorous dispersal by scavengers facilitate sexual reproduction in otherwise clonal plants at cadaver sites
(Peer reviewed; Journal article, 2022)1. The regeneration niche of many plant species involves spatially and temporally unpredictable disturbances, called recruitment windows of opportunity. However, even species with clear dispersal adaptations such as fleshy ... -
Diving behavior in a free-living, semi-aquatic herbivore, the Eurasian beaver Castor fiber
(Journal article; Peer reviewed, 2017)Semi-aquatic mammals have secondarily returned to the aquatic environment, although they spend a major part of their life operating in air. Moving both on land, as well as in, and under water is challenging because such ... -
Herbivore grazing—or trampling? Trampling effects by a large ungulate in cold high- latitude ecosystems
(Journal article; Peer reviewed, 2017)Mammalian herbivores have important top-down effects on ecological processes and landscapes by generating vegetation changes through grazing and trampling. For free-ranging herbivores on large landscapes, trampling is an ... -
Host in reserve: The role of common shrews (Sorex araneus) as a supplementary source of tick hosts in small mammal communities influenced by rodent population cycles
(Peer reviewed; Journal article, 2022)Rodents often act as important hosts for ticks and as pathogen reservoirs. At north -ern latitudes, rodents often undergo multi- annual population cycles, and the peri -odic absence of certain hosts may inhibit the survival ... -
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 ... -
Island biogeography theory explains the genetic diversity of a fragmented rock ptarmigan (Lagopus muta) population
(Peer reviewed; Journal article, 2019)The island biogeography theory is one of the major theories in ecology, and its applicability to natural systems is well documented. The core model of the theory, the equilibrium model of island biogeography, predicts that ... -
Life histories and ecotype conservation in an adaptive vertebrate: Genetic constitution of piscivorous brown trout covaries with habitat stability
(Journal article; Peer reviewed, 2018)Ecotype variation in species exhibiting different life history strategies may reflect heritable adaptations to optimize reproductive success, and potential for speciation.Traditionally, ecotypes have, however, been defined ... -
Litter loss triggers estrus in a nonsocial seasonal breeder
(Journal article; Peer reviewed, 2014)Sexually selected infanticide (SSI) is often presumed to be rare among seasonal breeders, because it would require a near immediate return to estrus after the loss of an entire litter during the mating season. We evaluated ... -
Merging and comparing three mitochondrial markers for phylogenetic studies of Eurasian reindeer (Rangifer tarandus)
(Journal article; Peer reviewed, 2016)Phylogenetic analyses provide information that can be useful in the conservation of genetic variation by identifying intraspecific genetic structure. Reconstruction of phylogenetic relationships requires the use of markers ... -
Optimal foraging by a large ungulate in an extreme environment: Wild mountain reindeer select snow-free feeding habitats in winter
(Journal article; Peer reviewed, 2021)Optimal foraging models predict that individual animals will optimize net energy gain by intensifying forage activity and/or reducing forage energy cost. Then, the free distribution model predicts an animal's distribution ... -
Seasonal and diel movement patterns of brown bears in a population in southeastern Europe
(Peer reviewed; Journal article, 2021)Most animals concentrate their movement into certain hours of the day depending on drivers such as photoperiod, ambient temperature, inter- or intraspecific competition, and predation risk. The main activity periods of ... -
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 ...
