Johan Hollander,
Assistant Professor

My interests within evolutionary biology are questions concerning phenotypic plasticity, speciation and evolution of local adaptation.

At present, I focus on mechanisms responsible to reduce gene flow between locally adapted populations, as well as the evolution of mating discrimination between geographically close taxa to avoid producing unviable hybrids – reinforcement. In order to study speciation I use marine gastropods as a model organism.

I am involved in a collaborating project studying phenotypic plasticity in the freshwater snail Radix balthica. Phenotypic plasticity is an important developmental strategy among prey organisms against predation, and freshwater snails are an important model organisms for studying traits that have evolved in association with various predators, including behaviour, morphology as well as costs of phenotypic plasticity.

I am also involved in a project for cod stock management in Öresund administrated by Lund University, “Multi-Dimensional Co-Management of Coastal Fisheries”. The aim of the project is, in collaboration with fishermen from the southern Sweden, survey the seasonal pattern of cod migration, and with molecular techniques and landmark-based geometric morphometrics, investigates how different cod populations contribute to cod stocks.

I am a Marie Curie Fellow and founded by the European Reintegration Grant
