Population of birds in the boreal mountain-valley landscape disturbed by gold mining

详细

The article characterizes the changes in the species composition and population of birds of the boreal mountain-valley landscape in connection with disturbances caused by extraction of gold (based on researched material in the Bureya Mountains, Far East). It displays the ratio of faunal assemblages and layered bird groupings in the technogenic habitats (lixiviation and open-pit dump sites of 1–5 years of age and 35–40 years of age) and undisturbed sites of river valleys. On the basis of coefficient of inclusion and similarity, we compared the populations of birds of different habitats either on species composition or taking into account the density of species.
