Ph.D. project

Ecology, life history and co-existence of a sympatric pair of Coregonus spp.

With Thomas Mehner, Jan Ohlberger, Susan Busch, Georg Staaks and Jörg Freyhof

(DFG Me 1686/5-1, within the priority program AQUASHIFT)

In my PhD I study the ecology and life-history of two closely related coregonid fish in a deep, oligotrophic lake (Lake Stechlin, northern Germany). It is suspected that the two species may have evolved in sympatry since the last glaciation. We want to elucidate the diversifying process and evaluate the ecological foundations for their co-existence. The two species reproduce at distinct times of the year, but in spite of different life-histories the two populations show rather low segregation in habitat and diet. My work focuses on comparisons of the two species in relation to depth-distribution, temperature preference, diet, morphology and larval recruitment.
