Current Distribution of the Introduced Rock Lizards of the Darevskia (Saxicola) Complex (Sauria, Lacertidae, Darevskia) in Zhytomyr Region (Ukraine)

Abstract

In the autumn of 2015 current distribution of the lizards of Darevskia (saxicola) complex, introduced in 1960s in Zhytomyr administrative region of Ukraine was studied. During the period from introduction until now Darevskia (saxicola) complex has spread along the left bank of the Teteriv River on the territory about 3.7 km lengths. Beside this was found an isolated population of this species, which located about at 4 km direct distance or 8.5 km shore line distance from the main area of occurring this species. It is supposed that this secondary introduction took place occasionally or intentionally due to holidaymakers (e. g. climbers, fishermen). The publication provides description of the lizards on 15 morphological characteristics and information on the results of spatial modeling potential distribution the rock lizards.

Importance of Utliukskiy Liman for the Protection of Waterbirds in the Azov-Black Sea Region During Autumn Migration

Abstract

Utliukskiy Liman is one of three typical and at the same time unique limans in the northwestern part of the Azov Sea Region of Ukraine. Despite the considerable anthropogenic transformation of the liman it continues to be a valuable wetland for migratory waterbirds. The current publication based on data collected from 1994 to 2015, in the period of autumn migrations 19 counts were conducted at Utliukskiy Liman. In total 1,134,832 ind. of 90 waterbird species (8 orders) were recorded. Averagely at liman were presented 59,728 waterbirds, with maximum 115,095 individuals. Throughout the season, many characteristics of waterbirds at Utliukskiy Liman are varying significantly due to the timing of migration of different waterbird species and their abundance. Detail information on this is presented in the paper. Among the counted birds, 60 species have certain conservations status. Maximum number of 20 counted species exceeded 1% of their geographical populations. According to obtained results, Utlyukskiy Liman occupies a stable place among the five most valuable wetlands of the Azov-Black Sea coast of Ukraine — in different years from 5th to 1st place on the total number of waterbirds.

The Amount and Distribution of the Red Data Book Bird Wetland Species in the Azov-Black Sea Region of Ukraine According to the Results of August Counts 2004–2015

Abstract

In the period from 2004 to 2015, in the Azov-Black Sea region of Ukraine and the adjacent territories five simultaneous August Counts covered all key coastal wetlands were conducted. They were primarily aimed at studying the abundance and spatial distribution of local water birds fauna, since that time there was hardly any migrations. In total 5.5 million birds of 133 species were counted during five August Counts. Forty species of them are included in the 3rd edition of the Red Data Book (RDB) of Ukraine, 35 of which are ecologically related to wetlands. The total amount of RDB birds was 179.5 thousand individuals, or 3.26 % of the total number of counted birds. Amount of birds varied from count to count between 21 and about 55 thousands of birds. In total 80 wetlands were covered by surveys, and in 73 of them (91.3 %), at least one time RDB species were recorded, that indicates the importance of the Azov-Black Sea coast for maintaining both local and migratory RDB birds. In five of the most valuable wetlands the percentage of counted birds from the total average value for all birds ranged from 5.3 % to 16.7 %, cumulatively making up 49.3 %. These are the following sites — Eastern Sivash, Lower part of the Ukrainian Danube Delta, Central Syvash, Kinburnskyi Peninsula, Lebedyni Islands.

Current Status of Anserinae Wintering in Azov-Black Sea Region of Ukraine

Abstract

In the article is analyzed own field data of the authors and scientific publications on the wintering of Anserinae in the Azov-Black Sea region of Ukraine in 1900–2017, but the main data was obtained in frame of international mid-winter counts (IWC) in 2005–2017. It was found that 9 species of Anserinae occur in this region during the different seasons of the year: Anser anser — nesting, wintering and migrating; Rufibrenta ruficollis, A. albifrons, A. erythropus, A. fabalis — migrating and wintering; Branta canadensis, Branta leucopsis, Branta bernicla, Chen caerulescens — vagrant or birds which flew away from captivity (zoo etc.). Eulabeia indica — is possible vagrant species. The most numerous wintering species is A. albifrons, common — Rufibrenta ruficollis, not numerous — Anser anser, the other species are not met annually and registered in a very small number. There was almost tenfold drop in number of wintering geese in the Azov-Black Sea region of Ukraine during the period of counts. The main reasons of such reducing of geese amount are the followwing: weather and climate conditions, changes in the forage acessibility, hunting and poaching pressure, poisoning as a result of deratization of agricultural lands, and from 2014 — the militarization of the Syvash area and stop of water supplying of Crimea through the North Crimean channell. It is likely that the factors mentioned above led to relocating of wintering areas of Anserinae, and resulted in decreasing of their amount in this region.

Terrestrial Molluscs in the Dry Grasslands of the DNIPRO Upland (Central Ukraine): New Records, Rare Species and Conservation Potential

Abstract

Thirty-six species of terrestrial molluscs were found in the dry grasslands and rock outcrops of the study area, including three that were not previously known for Central Ukraine: Granaria frumentum, Pupilla bigranata and Mediterranea inopinata. These species are relics related to dry open habitats and require conservation in Ukraine on the national level, G. frumentum is already listed in the Red Book of Ukraine, and the other two should be listed in its next edition. It is proposed to create the new protected areas in the most important newly revealed locations of these species. These rocky areas also retain the high diversity of land molluscs in the region. The invasive snail Xeropicta derbentina was found for the first time on the DNIPRO Upland, on the edge of natural dry grassland. The rare native snail Morlina glabra was recorded for the first time in Kyiv Region, it is proposed to be included into the regional red list.
