Description : This monograph is about predation in vertebrate animal community. The studies were done in the seminatural terrains with transitional mixed forest within the European forest zone in Belarus. The result part was organised as a top-down flow: First, the community characteristics related to predators were estimated. I presented data on predator species richness, population density and biomass with special attention paid to the changes in predator species diversity occurred during the last two centuries and particularly in connection with the American mink and raccoon dog naturalization. Then, the main features of predator food niches were given, and the structure of various predator guilds and size structure in predators were analysed. The next part of the monograph was devoted to examining of community-important factors acting in semi-natural terrains. Such factors affected either the whole community or its marked fragment. The last quite a large part of the monograph consisted of many chapters which present more or less essential results on different predator species, and stresses hot questions of their population ecology.

Description : This scientific monograph gives a detailed information about reproduction biology in the grey wolf Canis lupus in Belarus. This topic includes the wolf breeding (mating and denning) behavior, fertility of the species and mortality of its pups. The initial material was not collected occasionally from wolf hunters and wolf pup searchers, but mainly gained by authors first-hand according to a well-set research design and long-term. By analyzing the gathered data, we became convinced that in the wolf reproduction biology there are more exceptions than rules. Therefore, the standard patterns of reproduction biology in wolves that are wide-spread in the published literature about the species we call as common beliefs that are given versus the wolf reality that we have found in Belarus. Concerning the non-standard features in the wolf reproduction biology, we revealed that multiple breeding in wolf pack is a common phenomenon, breeding of yearling females and wolf-dog hybridization were found to be irrespective the food base and strongly depending on the species population density i.e. they are reproduction regulations. Wolf pup mortality was investigated and the crucial role of deliberate predation of lynxes on wolf pups was revealed.
