We studied experimentally male distribution in relation to key resources, food and females, during winter and at the onset of breeding in eight enclosure populations of the bank vole Clethrionomys glareolus. In the experiment we manipulated the social environment of individuals under thick snow cover. After we had determined the male movements in a mixed population of both sexes all females of each enclosure were captured and kept in a cage at one end of the enclosure while food was offered in the opposite end. Male movements between these two patches were monitored by life-trapping under the snow. We found a seasonal pattern in the distribution of males in relation to key resources. 1) During the non-breeding season the manipulation of female and food distribution did not affect the male movements significantly, but 2) as expected, at the onset of breeding females were the preferred resource for the males. The results are discussed in the light of survival and mating strategies of males. ...

Selection on two behavioral genes : fitness effects of receptor genes for arginine vasopressin 1a and oxytocin in the bank vole Myodes glareolus Lönn, Eija (University of Jyväskylä, 2017)Most variation in behavior is regulated by genes; nevertheless the mechanisms behind maintenance of genetic diversity at behavioral loci have remained mainly elusive in natural populations. I studied in my thesis ...

State-dependent foraging: lactating voles adjust their foraging behavior according to the presence of a potential nest predator and season Liesenjohann, Thilo; Liesenjohann, Monique; Trebatická, Lenka; Sundell, Janne; Haapakoski, Marko; Ylönen, Hannu; Eccard, Jana A. (Springer Berlin Heidelberg, 2015)Parental care often produces a trade-off between meeting nutritional demands of offspring and the duties of offspring protection, especially in altricial species. Parents have to leave their young unattended for foraging ...
Predation risk shaping individual behaviour, life histories and species interactions in small mammals Trebatická, Lenka (University of Jyväskylä, 2009)Trebatická havaitsi, että Suomen yleisin nisäkäs, metsämyyrä, on erittäin hyvin sopeutunut lyhyen lisääntymiskauden tehokkaaseen käyttöön ja pahimpien petojen välttämiseen. Parempi pedonvälttäminen kuin esimerkiksi toisella ...
