Veronika Bokony

I’m in love with behavioral ecology. The affair began with a PhD project on the evolutionary significance of plumage coloration in birds. It grew into a decade-long research on avian ecology, behavior, and evolution, increasingly focusing on the effects of habitat urbanization and other kinds of human-induced environmental change. Then we went on a second honeymoon and shifted the focus to amphibians, still going strong on the ecological and evolutionary consequences of environmental change. Nowadays, it’s mostly about sex – specifically, about environmental effects on sex determination, sexual development, and sex ratios in ectothermic vertebrates.
