A male of the Speckled Wood butterfly (Pararge aegeria) initate a courtship without success. The female is recently mated with another male and hence not receptive to the male's mating attempts. The butterflies shown in this video are from Madeira, but the Speckled Wood butterfly is also a common species in Sweden. The Speckled Wood butterfly has successfully been used as a model organsim in several fields in biology, such as beavioural ecology and life history evolution.

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

Research

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.

Man's best friend, the dog, may have been around far longer than we thought

A new study of dogs' genes shows that the dog's predecessor was separated from the wolf already sometime between 27 000 and 40 000 years ago. Analysis of the genome from a prehistoric wolf from the Taimyr Peninsula in Russia shows that it probably was the common ancestor of today's wolves and dogs.

Forskning på varg och hund vid Zoologiska institutionen

I en intervju i Rapport den 12 maj riktar Mats Amundin kritik mot pågående forskning om skillnader i beteende mellan hund och varg vid Zoologiska institutionen. Han hävdar att det finns risker med forskningen och att den inte kommer att ge ny kunskap. Vi håller inte med om detta och vill bemöta kritiken.

Stor hjärna hjälp mot rovdjur

Att ha en stor hjärna kan ge överlevnadsfördelar. I alla fall om du är en guppyhona. En ny unik studie publicerad i tidskriften Ecology Letters visar att guppyhonor med stora hjärnor löper mindre risk att bli uppätna jämfört med honor med mindre hjärnor.
