Research interests



Ecological constraints and genetic factors are recognised as key factors promoting cooperation in animals. How they affect the evolution of cooperation and sociality is studied on various biological models, especially ants. Our researches focus on the study of (1) the genetic structure of colonies and populations, (2) the reproductive and dispersal strategies, (3) sex ratio evolution, and (4) the proximate (how?) and ultimate (why?) causes of social conflicts and their resolution within societies. They are based on a combination of ecological and behavioural studies under natural (field) conditions, as well as on molecular analyses involving typing of microsatellite marker loci, flow cytometryic analyses, fluorescent sperm marking, or in situ hybridisation.
