On 2nd-3rd May, we had our spring seminar together with the Landscape biodiversity workgroup in western Estonia. The seminar was about methods in ecology and we heard many interesting talks about modelling, genomics and ecosystem services assessments. We were happy to have Raul Vicente Zafra, professor of data science at our university, as a guest speaker. He introduced the methods of machine learning and deep learning and how to apply them in ecological science. We also had some time to walk on the species-rich wooded meadow in Laelatu and contribute to the citizen science project sampling cowslip heterostyly for genetic diversity.
