Abstract
The complete cycle of the structure transformation of shrew model taxocene in southern Sakhalin was revealed by investigations of 2008-2014. It was shown that in the communities of these animals facultative and obligate dominants are absent and a dominant group is formed every year of common species. There are two main patterns of the taxocene structure: the monodominant type, predominating by the long-clawed shrew at low number of other species, and the polydominant type, in which one of the background species plays a role of codominаnt at a lower number of long-clawed shrews. It is found out that the dominanct structure in shrew taxocene is not closely related to the phase of its quantitative dynаmics.
