Dynamics of structure of shrew taxocene in southern Sakhalin

详细

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 codominant at a lower number of long-clawed shrews. It is found out that the dominance structure in shrew taxocene is not closely related to the phase of its quantitative dynamics.
