The Polish Evolutionary Conference is an annual meeting of the broad-sense evolutionary biologists from Poland and around. This is a small conference with several sessions of contributed talks, and long breaks facilitating networking. We particularly encourage young researchers to come and present their work in a friendly atmosphere. This year, PEC conference is aimed at integrating micro- and macro worlds. Besides traditional topics such as evolutionary ecology, there will be sessions on evolutionary processes at the cellular scale, such as endosymbiosis, adaptation of microbial organisms to changing environment, host-microbial interactions, and many more! 📅 When? 8-10 September 2025 📍 Where?
