RESEARCH INTERESTS Ecology, Animal Behavior, Freshwater Biology and Evolution
Our research examined evolutionary dynamics in crustacean species complex, with a focus on how ecological processes interact with genetic and biogeographic processes to determine speciation and phenotypic evolution. Additionally, we investigated the evolution of mating behavior, with an emphasis on the role of ecological setting in shaping costs and benefits of female choice.
