Wolf breeding peculiarities

In Europe and wider in Eurasia between wolf researchers and in the circle of other wolf-related people (e.g. hunters specialising in killing wolves, wolf pup searches) there is a widely spread belief on wolf reproduction that wolves are strictly monogamous species with a certain way of breeding and family pattern of pack formation. Actually, in my study in Belarus since the late 1990s there have been found so many abnormalities in those, that I start to think about what actually prevails in the wolf reproduction and packing: the “rules” or “exceptions”. Such “abnormalities” occurring too often are a very interesting phenomenon and they need to be further investigated.  Continue reading “Wolf breeding peculiarities”

The essential changes in my research establishment that happened in 2015-2017

For more than thirty years, till 2016 I had worked for the Institute of Zoology of the National Academy of Science of Belarus. But with time I started noticing that my working time was more and more wasted on the continuous applying for projects, reporting and very time-consuming presenting of the results in scientific journals. There was not enough time for the study itself.  But  if even a quite successful  zoologist neglects this applying-reporting-presenting chain,  soon he will appear without a financial support. So it seems the only way for a reseracher to be employed as a zoologist with some financial resources is to stay at a computer screen. Such a system in zoology seems to act all around the world, when an experienced zoologist should spend the main working time like that. I got convinced that, at least, it is true for zoology of vertebrate animals,  the field I have worked in for more than 30 years since 1984.

Investigation on the lynx population biology (general information)

Since the early 2000s I have paid more and more research attention to the lynx Lynx lynx. At that time there were not much known about the species in Belarus. Thus for the beginning I raised only regionally important questions of the lynx ecology, which had been investigated in other parts of the species range, but seemingly they are not entirely answered still somewhere as well as in Belarus. Among  the basic ecological questions I considered the most common ones such as the  species population number and habitat carrying capacity, distribution of lynxes in its between-year and seasonal changes, home range and its structure,  prey supply and  foraging, diet in its between-year and seasonal changes, lynx predation impact on the prey populations, reproduction rate and mortality causes.

Investigation of the wolf population biology (general information)

Since 1999 I have shifted own efforts on the study on the wolf Canis lupus population ecology.  In 1996-1998 in Paazierre Forest (mainly in the Lovat terrain), the northern Belarus  there were fulfilled studies on the wolf diet in relation to the dramatic changes in the preystock and on breeding in wolves. The research on the question of the species breeding had been continued there until 2005.  However,  since 2000 the main study area on wolves has been replaced in Naliboki Forest and its rural-forest surroundings.  The species reproduction and breeding behaviour have become the main pressing questions of my zoological study.

Reading mammal activity signs

Since my childhood I have been very interested in tracks of mammals and  in the entire variety of activity signs of mammals and birds on the whole.  Within this my passion I tried to push forward not only identifying of mammal activity signs, but their usage in track-based research methods on population ecology as well as to reconstruct correctly the respective behavior of mammals from their activity signs.  Continue reading “Reading mammal activity signs”

Analysis of predation in vertebrate community

In the period of 1993-2010 I led the Vertebrate Predation Research Group in the same research Institute of zoology, National Academy of Sciences of Belarus. The group consisted of 3-12 colleagues (including PhD-students and Diploma-students) and was aimed to investigate vertebrate predators,  mainly carnivores, but also owls, diurnal raptors and snakes. The studies took place in Paazierre Forest (the northern part of Belarus) and Naliboki Forest (the central-western part of Belarus), i.e. semi-natural terrains with transitional mixed forest within the European Forest zone.
