Martin Zobel (born 25 February 1957 in Tallinn) is an Estonian plant ecologist and professor at the University of Tartu. His name is particularly associated with the idea of an impact of regional species diversity on diversity at smaller spatial scales – known as the species pool effect. He has been professor since 1992. He has served as Editor-in-Chief of the scientific journal Ecography. Zobel has appeared several times on Clarivate's annual lists of influential scientists every year from 2017 to 2021. Zobel, M.
