| Popis: | Behavioural tests measuring locomotor activity of single individuals and groups of animals of the same sex have been performed on samples of Microtus agrestis from a cycling population in northern Sweden and a non-cycling population from south Sweden. The activity was higher for animals from the northern population. The differences were more pronounced for males than for females and more for group than for individual activity. The genetic control of this behavioural trait was confirmed by breeding tests. Pure-bred offspring from wild-trapped voles within each area did not deviate from the performance of their parents. The hybrid offspring had intermediate test values. An association between behaviour and population density phase is indicated for the cycling population, but a full cycle has not yet been followed. |
