Pavlo Yanushko, a researcher of mammals of the Ciscaucasus, Kazakhstan, and Crimea

An essay about a zoologist born in the Dnipro region who made a long way as a researcher from the steppes of Stavropol (plague service) and the mountains of the western Tien Shan (Aksu-Jabagly Reserve) to the Crimea (protected hunting ground, later the Crimean Nature Reserve). As a theriologist, the researcher is best known for his studies of marmot ecology and survey methods of mountain sheep (Turkestan period), and later he was well-known for his studies of the state of populations, population dynamics, ecology and reproduction of various groups of ungulates (Crimean period). Among the objects of his research in the Crimea were the mouflon, roe deer, and red deer, the latter being the subject of several articles by the researcher.
