Abstract

At given time, wisent’s metpopulation in Ukraine is in the state of resumption of biological characteristics of this species, which determines the need to control for the animals origin. Such studies assess the condition of each subpopulation, as well as to carry out the selection measures for conservation of the overall genetic variability of species. In modern conditions the success of wisent restoration depends on implementation of the national and international programs, the help of maecenas, the scale agitation among the peoples as well as the interest of users of hunting grounds and conservation areas.

Abstract

Over the years 2005–2012 avifauna was studied of 17 waste water treatment plants, located in the Chernihiv and Sumy Regions (northern left-bank) of Ukraine. 81 species of 30 families and 14 orders were registered. Taking into account landscape and technological peculiarities of the waste water treatment plants the follows zones of the birds’ distribution were distinguished: zone of water areas, agro-meadows zone, zone of dams, technological zone. It was noted that birds occurred in different zones unevenly. Maximal species number and diversity of ecological structure of the breeding avifauna was noted within the water bodies and dams. In terms of landscape-biotopic characteristic in waste water treatment plants dominated dendrophilous and wetland birds.

Abstract

A new distribution boundary of the dice snake, Natrix tessellate (Laurenti, 1768), in Ukraine has been established. The northern edge currently lies within the valley of the middle course of the Dnipro River: Trakhtemyriv Peninsula, Cherkasy Region on the right side (49°59′ N, 31°25′ E); on the left side in Kyiv Region within Pereyaslav-Khmelnytsky District: at a fishermen’s station (50°02' N, 31°17' E), yacht club (Kurinoye Estuary 50°02′ N, 31°29′ E); Lubny, Poltava Region (49°58 N, 33°01′ E). These points are located 70-80 km northwards from the previous boundary of the species home range. The level of Natrix tessellata population polymorphism in the North of Cherkasy Region is high; more than 40 % of specimens are dark-colored.
