Identification of Myotis blythii and M. myotis (Chiroptera, Vespertilionidae) from Eastern Europe Based on the Measurements of Lower Teeth. Ghazali M. A. — Since the shape of lower teeth is similar in Myotis species, it was the size that was used for differentiation between them. Canonical variates analysis was used to determine the possibility of discrimination between M. blythii Tomes, 1857 and M. myotis Borkhausen, 1797 based on lower teeth. The lengths and widths of canines, premolars and molars were measured. More than 89% of the specimens were correctly classified in the models built using measurements of each tooth separately (“one-tooth” models). Better result was obtained for different combinations of the teeth. The largest and the most frequent in the fossils teeth (c inf., p/4, m/1, m/2, and m/3) were chosen for “several-teeth” models. Sets of three teeth maximize the discriminatory power almost to 100%.
Key words: canonical variate analysis, lower teeth, Myotis blythii, M. myotis, Eastern Europe.

The Unique Paleontological Finding of the Fossil Ostracoda Cyprideis torosa (Arthropoda, Crustacea) in the Pleistocene Deposits of Ukraine. Dykan N. I., Permakov V. V., Olshtynska O. P. — The unique paleontological finding of the soft body mummified remains of the female Cyprideis torosa (Jones, 1850) (was found in Upper Pleistocene deposits (Novoevksinsky horizon, 9–13 000 years ago) in the Dnieper-Bugsky estuary (the north-western shore of the Black Sea, Ukraine). There are the legs (antenna, antennule, mandible, maxilla, maxillule, the first and third thoracic legs) and the fragments of the cross-striated muscles. The good preservation of the legs had been permitted to make more exact the information about the morphology of the antenna, mandible, maxilla, maxillule; at the first to show the photos of the cross-striated muscles structure, the streaky-cellular cuticle of the mandible branchiomeric appendage and its plumose setae, the teeth of the mandible masticatory surface. It was made X-ray analysis of the soft body mummified remains and the iron disulfide framboids which structurally connected with the soft body remains. It was grounded the biogenic nature of the iron disulfide framboids. The mummified remains photographs (30 ill.) had been taken by SCAN JEOL JSM–6490LV (õ110–2500).
Key words: Upper Pleistocene, Ostracoda, mummified remains, morphology of the legs, muscles.

Early Embryogenesis Peculiarities of the Planarian Dugesia lugubris (Turbellaria, Tricladida). Kanana Yu. P. — Åarly embryogenesis of the planarian Dugesia lugubris O. Schmidt, 1861 on the dated material is studied. The polygonal type of yolk cells is shown to be the only type initially existing in the cocoon of D. lugubris, and fusiform cells are formed later, probably, influenced by grouping factor. It is also found that the embryonic epithelium and embryonic pharynx are formed simultaneously.
Key words: embryogenesis, turbellaria, planarian, yolk cells, early cleavage, embryonic epithelium.

On the Migration of Cystacanths Sphaerirostris picae (Acanthocephala, Centrorhynchidae) in Paratenic Host Lacerta agilis, Histopathology. Krasnoshchekov G. P., Lisitsyna O. I. — The penetration mechanism of Sphaerirostris picae cystacanths in intestinal wall of the paratenic host Lacerta agilis and characteristic features of inflammatory changes in host intestinal wall are examined. Inflammatory reaction is characterized by predomination of eosinophiles and comparatively small amount of neutrophiles. The reaction is much more pronounced when cystacanth is placed in parallel to the wall of intestine. Extensive edema, plethora, stases in vessels, and slight hemorrhages are observed in submucous membrane. Inflammatory infiltration is less pronounced in case of perpendicular orientation of the proboscis. The secretory glands in cystacanths were not found, secretion on the tegumental surface was not seen, as well as no morphological effect of lytic enzymes on host tissues. The penetration of host intestinal wall is shown to be mechanic, advancement of the cystacanth through the wall of intestine is due to alterations of partial evagination and invagination of the presoma in combination with contractions of the metasoma.
Key words: acanthocephala, cystacants, paratenic, hosts, histopathology, migration.

Distribution and Spatial Dissemination of Crustacean Plankton (Crustacea, Cladocera) in Water Bodies of Chornohora Massif (Ukrainian Carpathians). Mykitchak T. I., Reshetylo O. S. — Twelve species of Cladocera were found in water bodies of the Chornohora. Chydorus sphaericus (Mu#ller, 1785) is the most widespread and numerous species on the investigated territory. Five basic complexes of Cladocera were distinguished according to the data of biotopic distribution in the Chornohora. They are as follow: phytophilic, littoral, pelagic, astatic, swamp. The specific feature of fauna of Cladocera of the Chornohora Massif is the presence of ice age relict species Daphnia obtusa Kurz, 1874. Biotopic heterogeneity favored by the size of water bodies has positive influence on increasing of species diversity in hydrocoenoses.
Key words: Cladocera, Carpathian Mountains, vertical and horizontal species distribution.

Analysis of the Genetic Structure of the Land Snail Cepaea vindobonensis (Gastropoda, Pulmonata, Helicidae) Population Based on RAPD-Marker. Kramarenko S. S. — Studied population of the land snail Cepaea vindobonensis (Ferussac, 1821) is shown to be highly polymorphic at RAPD-marker (h = 0,236). However, genetic subdivision of this population (Gst = 0,3142) is generally determined by random factors rather than geographic distances between samples. The gene flow is significantly important (Nm = 1.288–2.345) to support the population genetic uniformity. The studied population is assumed to be represented by discrete half-isolated patches fitting the Wright’s “island model” as the population’s land snail C. vindobonensis effective number is estimated to be low (Ne = 34–571).
Key words: genetic structure, RAPD-marker, population effective number, C. vindobonensis, Ukraine.

Present State of Lesser Spotted Eagle Population, Aquila pomarina (Aves, Falconiformes), in Ukrainian Carpathian Mountains. Vetrov V. V., Gavrilyuk M. N., Domashevsky S. V., Milobog Yu. V. — The material was mainly collected in 2005 on territories of four regions of Western Ukraine within Carpathian area. Point counts were chiefly used. 79 territorial pairs were found. The number of breeding birds is estimated as 140–160 pairs. The species is distributed irregularly; it is absent where the altitude exceeds 800 m above sea level and in continuous forest stands. Main feeding habitats are meliorated meadows, haylands and fields. Distribution of the Lesser Spotted Eagles in the Carpathians is discussed.
Key words: Lesser Spotted Eagle, distribution, numbers, feeding habitats, Ukrainian Carpathians.

Species Composition and Ecology of the Hydropolypes (Hydrozoa, Cnidaria) of Laspi Bay (Southern Coast of Crimea). Murina V. V., Grintsov V. A. — The taxonomic composition of the Hydrozoa from the upper coastal zone of the Laspi Bay (south coast of Crimea, Black Sea) is investigated for the first time. Material was collected in the diverse seasons in 2005–2007. 11 species of 6 families are identified. Five species: Pachycordyle aff. napolitana (Weismann, 1883), Ventromma halecioides (Pallas, 1766), Laomedia exigua (M. Sars, 1857), Campanularia integriformis (Marktanner—Turneretscher, 1890) and Gonothyrea loveni (Allman, 1859) are rare for the Black Sea. The most diversity of the species was revealed in spring and summer seasons.
Key words: Hydrozoa, distribution, ecology, Laspi Bay, Black Sea.
