Abstract

A. V. Matsyura

The problem of the mathematical analysis of dynamics of number of key colonial breeding waterbirds regarding to the islands of region is considered. The algorithm of an estimation of changes in number of birds is offered in scope of specific features of colonies and habitats. The data of long-term monitoring of island birds’ number have been analyzed according to proposed algorithm. On the basis of analysis results the necessity of use of the statistical indexes expressing the tendencies of changes in bird number and bird turnover is proved. For the key species of island communities the tendencies of changes in number are determined within the limits of researched region. The discussed technique of a complex estimation of breeding island bird dynamics is offered for the use at drawing up the management plans and development of nature protection actions with the purpose of conservation of bird diversity and their habitats.
