Ecological Population Status of the Most Common Bird Species in Northern Altai Low-Mountain Forests and the Principal Difference in Avifauna Status in Altai and Baikal Regions

Autor: S. E. Cherenkov

Publikováno v: Contemporary Problems of Ecology. 13:590-599

In 2016 and 2017, from April to July, bird individual nesting home ranges were regularly mapped along the permanent census route (2.8 km) in the low-mountain forests dominated by pine and birch. For each bird species, the nesting densities and averag

Ecological Status of Populations of the Most Common Bird Species in the Dark-Coniferous Taiga of Baikalia

Autor: S. E. Cherenkov

Publikováno v: Contemporary Problems of Ecology. 12:231-237

Nesting home ranges of individual birds were regularly mapped in 2013 and 2014 from May to July along a permanent census route (3.15 km) in the dark-coniferous taiga on the southern slope of the bed of Lake Baikal. Based on the mapping results, the n

An approach to evaluating ecological status of populations in forest-nesting birds (Passeriformes and Piciformes)

Autor: S. E. Cherenkov

Publikováno v: Contemporary Problems of Ecology. 10:203-214

A 13-year study of forest-nesting birds (orders Passeriformes and Piciformes) has been conducted at five constant census areas in European Russia, Caucasus, and the mountains of Southern Siberia. The nesting individuals are mapped at each census area

Autor: A. S. Golubtsov, S. E. Cherenkov, Fekadu Tefera

Publikováno v: Journal of Ichthyology. 52:817-820

Four sympatric forms of the genus Garra (Cyprinidae) differring in external morphology are reported from the middle reaches of the Sore River belonging to the White Nile system in southwestern Ethiopia. Additionaly, two Garra specimens exhibiting unu

Frequency distribution of minimum distances between singing males in different chaffinch (Fringilla coelebs L.) populations as an indicator of habitat quality

Autor: S. E. Cherenkov

Publikováno v: Russian Journal of Ecology. 42:38-43

The results of census mapping over nine nesting seasons have been used to calculate frequency distributions of minimum distances between male singing chaffinches. Comparison of these distributions shows consistent, high, and significant similarity of
