The 15th edition of the Ecology & Behaviour meetings will take place in Strasbourg from 21 to 24 March 2022. Since 2005, these scientific meetings have been organised by and for young scientists (masters, PhD students and post-docs). We are calling for talks and posters addressing diverse questions in ecology, evolutionary biology and animal behaviour: applied ecology, population dynamics, impact of climate change, biomonitoring, animal behaviour and cognition, physiology and evolutionary ecology.
