Повний текст джерелаAccording to foraging theory, animals seek and consume food in ways that maximize their ability to reproduce and have their genes represented in future generations. In order to achieve this, individuals must sometimes adapt their behaviors. Females of the brown bear (Ursus arctos) with cubs of the year must share the food they find with their cubs. To protect the cubs from being killed by males in the mating period, females with young have smaller home ranges than other adult females and move less on a daily basis than other females. In view of these differences my hypothesis is that females with yearlings consume different food items than other females. A fecal collection from GPS-marked brown bears was made in 2015 in the northern Dalarna county and northwestern county of Gävleborg in Sweden from 25 May to 11 October. Prior to the data analysis, the season was divided into two periods, 25 May to 15 July and 16 July to 11 October, based on differences in food availability and season (mating vs non-mating season). A frequency analysis detected no significant differences in food items consumed for either period. However, an exploratory data analysis of percent volume of different food items suggests that there may be differences in the amount of certain foods during the mating period. These differences were found for the food categories, bone, moose hair and other plant material. Although the study suffers from a small sample size with only four females with cubs of the year in each of the two periods, this study is relatively novel with a resolution at the individual level. Previous food item analyzes of the brown bear in Scandinavia have been done with fecal samples as the smallest unit.

Повний текст джерелаTiivistelmä Suurpetojen luonnonpopulaatiot hävisivät Euroopasta melkein kokonaan viimeisten vuosisatojen aikana. Ruskeakarhujen määrä on viime aikoina kasvanut Pohjois- ja Itä-Euroopassa, ja karhupopulaatiot ovat toipuneet tai toipumassa. Tieto demografisen toipumisen geneettisistä seurauksista populaatioissa on varsin rajoittunutta etenkin laajemmassa maantieteellisessä mittakaavassa, yli valtiorajojen. Keräsimme tätä tutkimusta varten 3757 uloste- ja karvanäytettä ja 881 kudosnäytettä Suomesta ja sen lähialueilta. Tarkoituksenamme oli kartoittaa Pohjois-Euroopan karhupopulaatioiden geneettistä rakennetta ja monimuotoisuutta, sekä populaatioiden välisiä yhteyksiä huomioiden ajallinen ja maantieteellinen ulottuvuus. Bayesiläisen ryhmittelyanalyysin perusteella Pohjois-Euroopan karhut jakaantuvat useaan geneettiseen ryhmään. Suomen populaatiossa erottuivat eteläinen ja pohjoinen alapopulaatio. Analyysit geenivirran määrästä osoittivat, että Etelä-Suomen ja Länsi-Venäjän karhupopulaatiot ovat yhteneväisemmät, kun taas migraatio Skandinavian ja Pohjois-Suomen sekä Etelä-Suomen ja Länsi-Venäjän välillä vaikuttaisi olevan rajoittunutta. Suomesta, Venäjältä ja Pohjois-Norjasta tunnistetut alaryhmät olivat geneettisesti hyvin monimuotoisia, ja muuntelu oli korkeampaa kuin koskaan aiemmin karhuilla havaittu. Suomen karhupopulaation toipuessa ja levitessä pohjoiseen, geneettinen erilaistuminen maan sisällä on vähentynyt ja eteläisen alapopulaation monimuotoisuus kasvanut. Tämä viittaa populaation laajentumiseen etelästä käsin. Tulosten perusteella karhujen tulomuutto Venäjältä on yhä tärkeää Suomen populaatiolle. Suomen ja Venäjän karhupopulaatioiden yhteyttä Skandinavian karhupopulaatioihin tulisi seurata ja parantaa

Повний текст джерелаThis thesis deals with the application ofmo1ecular tools, combined with field data, in wildlife management, in conservation and in understanding biology and behavior of the Scandinavian brown bear (UrslIs arc/os). The first part of this thesis is a methodological part, in which we deve10ped or reviewed technical aspects in molecular biology (particularly, we defined protocols to ampli fy DNA from fecalsamples) and in parentage analysis; the second part is devoted to the application of molecular genetics for managing Populátions. We evaluated several population size estimators, either from non invasive sampling é1lldmolecular methods, or from traditional field methods, and determined that the most reliable estimator was the one from programm MARK, based on a capture-mark-recapture principle, from genetic data. The brown bear populationin sweden was estimated to be around 2200 individuals in 2004. The brown bear mating system was studied in relation with sexually selected infanticide (SSI), from parentage analyses studies. SSlmight be an adaptive male mating strategy. Fema1es might employ counter strategies such as multiple male-mating to confuse paternities and mating with future potentia11y infanticidalmales. Most heterozygous and leu'ger males would be preferentially selected by females, probably through a post copulatory mechanism

Повний текст джерелаThe study of behavioural plasticity aims at understanding the physiological and behavioural responses of individuals to limiting factors. Climate change has the potential to influence the life history of individuals by altering environmental conditions. Thus, studying the mechanistic links between animal behaviour and environmental conditions is necessary to understand the potential impacts of climate change on individuals. The first part of my thesis focuses on the links between environmental conditions, hibernation behaviour, and habitat selection of grizzly bears, a threatened species in Alberta, Canada. The phenology of den entry and exit was driven by sex and reproductive status, food availability in autumn, winter precipitation, and spring temperature. There was no difference in the dimensions and characteristics of dens excavated by male and female grizzly bears, and males and females selected similar landscape attributes to dig their dens. At the broadest scale investigated, grizzly bears avoided wetlands and selected high-elevation dry conifer stands with abundant high-quality spring foods. At the home-range scale and within the den vicinity, grizzly bears selected dense conifer stands associated with little high-quality autumn food and abundant Hedysarum spp. in areas with low road densities. The second part of my thesis focuses on the links between habitat selection and thermoregulation during the active season, and highlights the thermal constraints associated with increasing ambient temperatures on habitat selection patterns. Grizzly bear habitat selection followed a daily and seasonal pattern that was influenced by ambient temperature, with adult males showing a stronger response than females to warm temperatures. With increasing ambient temperatures, male and female grizzly bears increased their selection for open stands with abundant food resources during the coolest periods of the day, and concurrently decreased their selection for these open stands during the warmest periods of the day. My thesis increases our understanding of the role of intrinsic and extrinsic factors on hibernation behaviour, habitat selection, and thermoregulation constraints of grizzly bears. Ultimately, my results enhance our understanding of the factors regulating the distribution of individuals in time and space; improving our ability to predict the potential impacts of climate change on large mammals.
