The main areas of research

We are a group of researchers connected by the study of evolutionary, ecological, and cognitive aspects of animal behaviour and information theory as applied to these. We combine an evolutionary ecology perspective with the study of both cognitive and stereotyped mechanisms that underpin evolutionary adaptations. We consider model groups the species of solitary and social rodents, the species of ants with different levels of social organization, colonial gulls, and single nesting passerines. We firstly treat the variability of behavioral stereotypes as one of the essential properties of personalities in animals. In recent years, the study of personalities as a sustainable combination of individual behavioral characteristics, such as boldness, caution, aggressiveness, exploratory activity, in different contexts has become an accessible and relevant area of evolutionary ecology. Personalities are associated with crucial manifestations of fitness such as survival and reproductive success. The question of the possible individual variability of holistic behavioral stereotypes has not been studied until now. The variability of cognitive characteristics in populations and communities has been little examined before. We investigate obligate behavioral stereotypes that are subject to significant selection pressure and therefore are slightly variable and optional ones, as potentially the most variable. As obligate behavioral stereotypes, we consider the interaction with offspring in ants and colonial birds, as well as some standardized species-specific patterns in all species studied related to foraging, protecting the territory, etc. The study of optional stereotypes is based on the behavioral model that we successfully found: insect hunting in rodents with different types of diets. As one of the essential mechanisms of behavior variability, we consider the role of personality in population processes. We explore the cognitive tools of decision making as the final link of adaptive tuning of populations in a changing environment. Experimental studies are based on original concepts and hypotheses developed by our research group in recent years: the hypothesis of ambivalent foraging, the idea of cognitive specialization in populations and communities, the theory of distributed social learning. A mathematical analysis of animal behavior is based on the data compression method elaborated by our group and related to the ideas of Kolmogorov complexity. We pay special attention to the practical aspects of studying the stereotyped and flexible behavior of animals from insects to birds and mammals. This kind of quantitative information is a basic need in the assessment of the effect of human activities on organisms, and allows us to monitor the threats posed by global change threats to the conservation of animal populations.
