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,

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

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,

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,

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
