Essay

Object is the heron's birds as a structural element biogeocenos. The aim is to study the herons as a structural element biogeocenos Northern Priazovie. A method of direct visual inventories, mapping, methods of statistical processing of results. The analysis of modern distribution, the dynamics of population of 8 species of the herons living in the Northern Priazovie, their ecological features and factors influencing their ecology are under consideration in the thesis. There are the characteristic of nested settlements and colonies of different ecological types: wood, reed and ground. The main reproductive parameters, afternesting moving and migrating phenology are also under consideration. The status of elementary population with the use oomorpfological parameters, and consortia and biocenotic connections in the reed type colonies are marked here. The spectrum of feed of herons nestlings is found out. The rating of a heron role in transformation of biomas and energy in ecosystem is conducted. The ways of seasonal migrations, and places of summer-autumn crowds and winterings are under analyses on the ringing data. The complex of measures to protect nested heron colonies is worked up. Sphere - manipulation of bird's colony, training courses.
