Monika Bukacińska, Ph.D.


Study objects: gulls and terns. Study area: the middle course of the Vistula River. Main study interests: (a) reproductive costs, breeding strategies and life history in different habitats and population conditions; (b) relationships between social structure of population and alternative breeding strategies and altruistic behaviour (extra-pair fertilization, intra-specific brood parasitism, adoptions, etc.); (c) brood sex ratio and lately (d) habitat protection and active species protection in Lari. Co-author of over 50 peer-reviewed publications. Member of  the British Ornithological Union, Ornithological Societies of North America, the International Society of Behavioral Ecology and Association for the Study of Animal Behaviour.
