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 ... -
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 ... -
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 ...
