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 джерелаThe very abundant polar cod (Boreogadus saida) plays a preponderant role in the Arctic marine ecosystem and consequently has received significant attention in recent years. The ice cod (Arctogadus glacialis), a common species in all Arctic seas, is much less studied. Both species co-occur on Arctic continental shelves and their early life stages are often found together in ichthyoplanktonic collections. However, larvae and juveniles of polar cod and ice cod are almost impossible to differentiate. Only genetic tools, or a method using the size of the otolith nucleus developed in this thesis, can distinguish the two species. These identification methods allowed to study for the first time ice cod early life stage ecology and estimate the proportion of this species in Arctic gadids samples. In light of observations made in the Beaufort Sea, it seems that young ice cod are about twenty times less abundant, hatch at a larger size, grow at the same rate, and have a mortality rate inferior to young polar cod. For polar cod, the hypothesis that some larvae hatch in winter near river plumes, was tested, first by comparing the hatching season in six regions of the Arctic characterized by different freshwater inputs. Consistent with this hypothesis, hatching starts in winter in seas receiving large river discharge while hatching starts in spring in regions with limited freshwater inputs. The larvae hatched in winter benefit from a long growth season allowing them to reach larger pre-winter size than larvae hacth in summer, a condition that likely favors their survival. This same hypothesis was further tested by comparing the otolith chemistry of polar cod juveniles from those six regions, and the differences observed seem to support the hypothesis. On-going trends of earlier ice break-up, warmer surface layer, and increased river discharge could favor polar cod, and possibly also ice cod, recruitment. Arise from this thesis an increased knowledge of the ecology of gadids living in an Ocean facing a plethora of changes.

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
