Sammanfattning : Altitudinal gradients offer attractive opportunities for studies of population differentiation in response to environmental heterogeneity. In this thesis, I examined population differentiation along altitudinal gradients by combining common-garden experiments with field studies and experiments in alpine, subalpine and boreal populations of the perennial herb Solidago virgaurea.

4. Hitting the mark studies of alterations in behaviour and fertility in ethinyl estradiol-exposed zebrafish and search related biomarkersDetta är en avhandling från Örebro : Örebro university
Sammanfattning : In this thesis, we have analysed the effects of EE2 on non-reproductive behaviours and fertility. We have showed that two doses of EE2 in male adult short-term exposures evokes opposite behaviours in the novel tank test. LÄS MER
