It is with regret we inform you that the 2020 Ecology and Evolutionary Biology Symposium, Turkey to be held at Koc University has been cancelled due to the rising threat of the COVID-19 pandemic. We would like you to know that we did not reach this decision lightly and after long consideration, both the EcoEvo board and the organizing committee of EEBST 2020 agreed that our first responsibility was to the prevention and spread of this deadly virus. Please be assured that we will be issuing refunds to all attendees and bodies that have registered thus far. Plans for organizing the 2021 meeting at Koc University, Istanbul are underway and we hope to see you all there. In the meantime please pay attention to all safety measures and practices necessary to combat this disease and stay healthy.
