The role of light structure stands Biosphere Reserve “Askania Nova” in shaping dendrophilous avifauna in the reproductive period

Abstract

Work was carried out on the territory of the Biosphere Reserve “Askania Nova”. Object of study – forest birds. Forest plantations in the reserve all artificial. This park, village and forest strip. They formed the population of birds. The laws by which the settlement occurs birds of these forests – the main task of the study. Forest ecosystem is a group of factors. They operate on different birds. In this paper we consider the role of such factors as light. Bird census was conducted in the spring and summer. Studied only those birds that inhabit the forest of artificial. In accordance with the doctrine of artificial forest steppe, we selected five lighting options. With respect to each of them, we studied the number of each species of birds. The study found what variant illumination prefers one or the other species of birds. Thus, we learned what kinds of birds in the forest light is a positive or negative phenomenon. What type of lighting is most fond of a particular species of bird. We learned that light helps to establish two community forest bird. These are the kinds of forest and steppe origin, as well as only forest. Marked species that are tolerant to light. For them, the light in the forest is not important. Birds that live in the trees and have a small body – the most sensitive to light. In spite of this, the darkest parts of the forest are not yet fully populated with birds. Here you can expect to see new species of birds and increase their numbers. On the contrary, in light of artificial forests of free living space is left. Here bird fauna is full and will not change.
