Lake Blanktjärnen is one of the sites of the Lakes Bävervattnen-project where the genetic composition of natural brown trout populations is monitored since over 30 years. The average effective population size is just around 70 in this lake.

Welcome to the Department of Zoology

The Department of Zoology has a long history, but is also very much with its time. It was founded in 1880, as the first at Stockholms University, and is continously changing to make room for new exciting research fields. The divisions for zoological ecology, ethology, morphology and population genetics are located in Arrheniuslaboratorierna, while systematics och evolution is mainly found at the Swedish Museum of Natural History. We also have a well-equipped research station a few miles south of Stockholm


Our current research is focused on animal evolution, ecology and behaviour, but within a broad spectrum from nervous system to ecosystem - on model organism from fruit flies and butterflies to fishes, birds and arctic foxes. Not even human is excluded - we take part in the interdisciplinary Centre for the study of Cultural Evolution. As part of the research programme Ekoklim we study ecological effects of the climate change. Our research is also theoretical within Stockholm Univerisity profile area biological modelling.


Ullhårig mammut på frimärke

Forskare vid Naturhistoriska riksmuseet och Zoologiska institutionen presenterade under 2015 den första kartläggningen av mammutens arvsmassa. Ett frimärke visar denna forskning.

Sneaky male behaviour leads to the evolution of faster sperm

Sometimes the best laid plans – and eggs – of fish go awry. In one species, females favor larger males, but female attention also unintentionally draws smaller males, which try to prey on a bigger fish's allure. That increased risk of rivals, scientists think, makes large males have unexpectedly speedy sperm.
