Polar bears have experienced a rapid loss of sea-ice habitat in the Barents Sea. Monitoring this subpopulation focuses on effects polar bear demography. In August 2015, we conducted survey Norwegian Arctic to estimate numbers and reveal population substructure. DNA profiles from biopsy samples ear tags identified photographs revealed that about half Svalbard, compared only 4.5% pack ice north archipelago, were recognized recaptures. The recaptured had originally been marked mostly spring....
Loss of Arctic sea ice owing to climate change is predicted reduce both genetic diversity and gene flow in ice-dependent species, with potentially negative consequences for their long-term viability. Here, we tested the population-genetic impacts reduced cover on polar bear ( Ursus maritimus ) sampled across two decades (1995–2016) from Svalbard Archipelago, Norway, an area that affected by rapid loss Barents Sea. We analysed variation at 22 microsatellite loci 626 bears four sampling areas...
Knowledge about the connectivity among natural populations is essential to identify management units for effective conservation actions. Conservation-minded has led recovery of large carnivore in northern Europe, possibly restoring between two separated, but expanding brown bear (Ursus arctos) on Scandinavian peninsula west and Karelia, a part Eurasian population, east. The degree these been poorly understood, therefore we investigated extent using autosomal microsatellites Y chromosome...
Knowledge about population genetic structure and dispersal capabilities is important for the development of targeted management strategies agricultural pest species. The apple fruit moth, Argyresthia conjugella (Lepidoptera, Yponomeutidae), a pre-dispersal seed predator. Larvae feed on rowanberries (Sorbus aucuparia), when rowanberry production low (i.e., inter-masting), moth switches from laying eggs in to apples (Malus domestica), resulting devastating losses crops. Using methods, we...
Several non-invasive methods for assessing stress responses have been developed and validated many animal species. Due to species-specific differences in metabolism excretion of hormones, should be each The aim this study was conduct a physiological validation an 11-oxoaetiocholanolone enzyme immunoassay (EIA) measuring faecal cortisol metabolites (FCMs) male reindeer by administration adrenocorticotrophic hormone (ACTH; intramuscular, 0.25 mg per animal). A total 317 samples were collected...
The apple fruit moth Argyresthia conjugella (Lepidoptera, Yponomeutidae) is a seed predator of rowan (Sorbus aucuparia) and distributed in Europe Asia. In Fennoscandia (Finland, Norway Sweden), production low every 2-4 years, (Malus domestica) functions as an alternative host, resulting economic loss crops inter-mast years. We have used Illumina MiSeq sequencing to identify set 19 novel tetra-nucleotide short tandem repeats (STRs) conjugella. Such motifs are recommended for genetic...
Despite the high density of brown bears (Ursus arctos piscator) on Kamchatka peninsula their genetic variation has not been studied by STR analysis. Our aim was, therefore, to provide population data from bear applying a validated DNA profiling system. Twelve dinucleotide STRs commonly used in Western-European (WE) populations and four additional ones (G10C, G10J, G10O, G10X), were included. Template input ≥ 0.2 ng was successfully amplified. Measurements precision, stutter heterozygous...
The autumnal moth (Epirrita autumnata) is a cyclically outbreaking forest Lepidoptera with circumpolar distribution and substantial impact on Northern ecosystems. We have isolated 21 microsatellites from the species to facilitate population genetic studies of cycles, outbreaks, crashes. First, PCR primers conditions were developed amplify 19 trinucleotide loci two tetranucleotide in six multiplex approaches then analyzed for specificity, sensitivity precision. Twelve showed simple tandem...
