Opportunities

PhD position in Ecological genetics


Collaborative projects with Dr. Anti Vasemägi

Topic: Adaptive differentiation of early-life stage phenotypic traits in whitefish (Coregonus sp.).

PhD project of Siim Kahar
Integration of ecological, experimental and genetic perspectives to investigate fitness related traits for conservation in salmonid fishes.


I am also searching a highly motivated student to conduct a research projects:

Synchrony of temporal variation of insect biomass with growth and abundance of Atlantic salmon

A project involving a mark and recapture study to estimate population size of a piscivore with a view to determine its function in regulating the abundance of Atlantic salmon


Biological interactions among invading sculpin (Cottus gobio), its naturally occurring parasite (Schistocephalus spp.) and Atlantic salmon
