Perceived Threats to Family Increases Women’s Willingness to Sacrifice During War


Researchers at the Universities of Turku and Helsinki found that women were more likely to volunteer for all-female paramilitary organizations if they had brothers or husbands who were currently serving in the military.  This result suggests that bonding with larger and frequently imagined communities, such as the nation state or religious groups, can arise from psychology mechanisms designed by evolution to increase cooperation among close relatives.

Research at the Department of Biology

We have a strong, versatile and internationally recognized research agenda in ecology, animal physiology, genetics and evolutionary biology. Many of our research projects integrate over the levels of biological organization and involve multi-disciplinary collaborations.

Destruction of Species – Researchers Discuss Biodiversity Crisis


Nature is becoming less diverse all across the globe, which is also threatening the future of humankind. Researchers emphasise the fact that there is still hope, but now is the time to act.

​Professors Kari Saikkonen and Ilari E. Sääksjärvi emphasise the need for protecting natural forests that are home to diverse species. In Finland, forests cover over 70% of the country’s surface area, but especially in the south most of it is commercial forest.

Amazon Research Team Wants to Open Its Collections


The University of Turku's Amazon Research Team's (UTU-ART) botanical acquisitions focus especially on ferns and medinilla plants. After spending weeks in the jungle, the researchers’ plant specimen findings end up in the University's Herbarium and databases. The Amazonia is home to innumerable unknown species and therefore it is important to develop the databases.

Shared Lifetime of Grandmothers and Grandchildren Significantly Increased Since 1800s


The importance of grandmothers in the lives of their grandchildren has changed. The shared lifetime between grandmothers and their grandchildren has a fundamental effect on how grandparents and grandchildren influence each other. A study conducted by biologists at the University of Turku, based on Finnish parish registers, indicates that, in this agrarian society, the shared lifetime of grandchildren and their grandmothers was short.

Capturing Elephants from the Wild Shortens Their Lives


Humans have been capturing wild Asian elephants for more than 3,000 years for different purposes, and this still continues today despite the fact that the populations are declining. An international team of researchers has now analysed records of timber elephants in Myanmar to understand the effects of capture on the animals and their survival. The study shows that even years after their capture, wild-caught elephants’ mortality rate remains increased, and their average life expectancy is several years shorter compared to captive-born animals.
