The Chernobyl Catastrophe from Zoologist’s Point of View. Kryzhanivskij V. I. — The ecological status of the Chernobyl exclusion zone and its fauna over 20 years after the nuclear catastrophe from the viewpoint of a zoologist is evaluated. Investigations of population dynamics of higher invertebrates in the exclusion zone show that the main factors, which determine the status of animals and trends in animal wildlife are secondary ecological effects connected with the absence of human activity. Ecological radioresistance of animal populations contributes to the renewal of faunistic complexes of the Polessie biogeographical region, favoring rare and endangered species too. A process of ecological rehabilitation of the polluted area is now underway. It is inferred that the largest ever in human history nuclear catastrophe has turned out to be an ordinary local catastrophe for nature, which has not inflicted much harm to the ecosystems and fauna. The exclusion zone and zone of absolute resettlement is the sole vast deprived of regular human population area located in the centre of Europe that may support genetically harmless populations of rare large herbivore and carnivore mammals. This area must be turned over into a biosphere reserve or a national park with extended functions such as of a core element of the ecological network of the Polessie.
Key words: exclusion zone, Chernobyl catastrophe, ecological radioresistance, radioactive pollution, ecological rehabilitation.

Zelotes kukushkini sp. n. (Aranei, Gnaphosidae) and Close Related Species from Palaearctic. Kovblyuk M. M. — Zelotes kukushkini Kovblyuk, sp. n. from the South of Ukraine is described. It differs from related Palaearctic species — Z. subterraneus (C. L. Koch, 1833), Z. fratris Chamberlin, 1920, Z. pyrenaeus Di Franco et Blick, 2003 and Z. sula Lowrie et Gertsch, 1955 by the shape of the embolus (shorter than in Z. subterraneus and Z. fratris, but longer than in Z. pyrenaeus and Z. sula — by the structure of embolar division of bulbus, and by the shape of epigyne and spermathecae canals. The structure of the epigyne and spermathecae of Zelotes kukushkini sp. n. are similar to those of Z. fratris. All the species (except Z. pyrenaeus) are redescribed and figured.

Elements of the Avifauna of the Crimea Mountain in Artificial Isolated Wood Areas of Kerch Peninsula. Tsvelykh A. N. — The species composition and number of birds is investigated in the remote artificial wood areas in steppes of Kerch Peninsula. Certain bird species (Aegithalos caudatus, Anthus trivialis, Phylloscopus sibilatrix, Coccothraustes coccothraustes, Buteo buteo, Pernis apivorus) formerly absent here, have been recorded now in artificial wood areas of the Steppe Crimea and neighbouring areas of the steppe zone of Ukraine. Distribution of other species of the tree and bush complex (Luscinia megarhynchos, Turdus merula, Sylvia atricapilla, Parus caeruleus, Parus major, Fringilla coelebs etc.) in the artificial wood areas is considered. Analysis of the “rain-call” of chaffinch's inhabiting Kerch Peninsula shows that they belong to the Crimean subspecies F. c. solomkoi. However, several individuals of the Caucasian origin are also registered. The remoteness of artificial wood areas in the steppe zone is not an essential obstacle for colonization by some species of birds. Appearance of these species in the wood areas depends on avail-ability of habitats potentially suitable for breeding. The source for colonization of artificial wood areas in the Steppe Crimea by forest birds is the avifauna of the Mountain Crimea.
Key word: avifauna, artificial wood area, steppe zone, Kerch Peninsula, Crimea.

Ñharacteristic of Reproduction Ability of Mouflon, Ovis musimon (Bovidae), which is Acclimatized under the Semi-Free Conditions of the South Ukraine. Steklenev E. P. — Sexual behavior of the European mouflon, Ovis musimon Pallas, 1811, which is acclimatized under the semi-free conditions of the South Ukraine is characterized by distinct seasonal impression of sexual reflexes, productive mating and progeny bearing. The period of sexual activity impression and productive mating of European mouflon females is restricted on the whole by autumnal and winter months with maximal conceptions indexes in November–December. By the favorable climatic and fodder conditions of some females who have lost their progeny can express sexual activity and mate in spring. The summer period of mouflon females is characterized as a period of sexual repose with fading gametogenesis, whose gradual activation begins in the end of the summer in the course of the daylight reducing. Strict seasonality of spermatogenesis in the mouflon males is not observed and they can mate in any period of the year. Mouflon males and females reach their puberty as a rule on the 3rd year of the life in the season of highest sexual activity; well developed animals may display sexual activity in the end of 2nd year of life. The reproductive ability of mouflon males and females is bound by 10–12 years of life.
Key words: mouflon, acclimatization, sexual season, reproduction, gametogenesis, mating, South of Ukraine.

The Temperature Adaptation of Microsporidia. Êilochitskiy P. Ya. — The Microsporidia thermal preference — it is a temperature adaptation span within certain species with their specific hostal characteristics and life cycle, but not in the whole phylum Microsporidia. The extreme temperatures influence oppressively on the poikilotherm animals’ microsporidia diseases of stopping or retarding sporogony process of the protozoa. In the case of mixtinvasions under the conditions of extreme temperatures another pathogens take over the microsporidia due to their own temperature adaptations. The opportunity of invasion of poikilotherm and homoiothermal animals by microsporidia during their one life cycle proves the existence of labile mechanism of their thermo-resistance.
Key words: microsporidia, temperature adaptation.

Mosesia riparia sp. n. (Trematoda, Pleurogenidae) — the Parasite of Intestine of the Sand Martin in Ukraine. Malega A. M. — Mosesia riparia Malega, sp. n. is described from the intestine of the sand martin (Riparia riparia L.) from Ukraine. Morphology of genital and excretory systems is studied by standard and histological methods. The new species differs from the closely related M. monedulae Oschmarin, 1965 by larger body and inner organs size. The new species was found in Vinnitsya Oblast (Ukraine), in sand martins only; it is absent in other martins and swallows occurring in that area. Both adult and young birds are found to be infected.
