Ontogenesis: a Phenomenon and a Process (on the Problem of the Evolution of Ontogenesis). Kovtun M. F. — An unconventional approach to the study and analysis of ontogenesis, based on the duality of its nature is proposed: in the first case this is a phenomenon, in second case it is a process. As a phenomenon, ontogenesis covers all manifestations of living, providing the continuity of life on all the levels of its organization, ensures lifespan of a species, regardless of the individual‘s life, and thus the dynamic stability of the cycle of matter and energy flows, the evolution cycles, the biosphere and life in general. As a process it is the implementation of ontogenesis by the way of successive morphogeneses. There is a gap between these components of ontogenesis (the phenomenon and the process) that must be filled out. This is a complex task in the scope of the ontogenesis evolution problem (making the theory of ontogenesis).
Key words: ontogenesis, phenomenon, process, morphogenesis, cycle of matter and energy, biologization, individualization, essence.

V. — The existence on the territory of Ukraine of two sympatric widespread species definitely different by their chromosome number was proved based on the meiotic chromosome preparations. Besides the nominal species Pontastacus leptodactylus (Dana, 1852) with modal haploid chromosome number n = 93 we prove the existence of P.?angulosus (Rathke, 1837) with n = 88.

Fauna of Chewing Lice of the Order Phthiraptera, Suborders Ischnocera and Amblycera, of the Rock Pigeon (Columba livia) in Ukraine. Soroka N. Ì., Sidorenko ². V. — The article takes a look at the distribution of different species of chewing chewing lice throughout the world, provides data on the composition of the species of chewing chewing lice of the Rock Pigeon in Ukraine. We found four species of chewing lice of the order Phthiraptera, of the suborders Ischnocera (family Philopteridae) and of the Amblycera (family Menoponidae). For the first time in Ukraine, type of parasite Coloceras damicorne Nitzsch, 1866 was described. Examination of 277 pigeons of two types (Columbalivia var. domestica, Gmelin, 1789; Columbalivia var. urbana, Gmelin, 1789) found 20,099 samples of parasites. Intensiveness and extensiveness of the hosts, points of localization, changes in development and behavior of the lice of the Rock Pigeon, were studied. The most common group was Columbicola columbae Linnaeus, 1758; Campanulotes compare Burmeister, 1838; while the most rare was Coloceras damicorne. The Hohorstiella lata Piaget, 1880 was the considerably more harm.
Key words: Rock Pigeon, chewing lice, Columbicola, Campanulotes, Coloceras, Hohorstiella.

Deep-Water Tardigrada of the Istanbul Strait’s (Bosporus) Outlet Area of the Black Sea. Kharkevych Kh. O., Sergeeva N. G. — The results of investigations of tardigrades (2009–2010) in the Bosporus outlet area of the Black Sea are represented. For the first time two species of tardigrades Dipodarctus subterraneus (Renaud-Debyser, 1959) and Tanarctus ramazzottii (Renaud-Mornant, 1975) are recorded for the Black Sea. Tardigrades are registered on 4 stations at depths range 88–250 m. Average abundance of tardigrades widely varied from 141 to 11 440 ind./m2. The vertical distribution of tardigrades in the sediments was analyzed: most specimens (up to 98 %) found in the top 0–1 cm sediment layer.
Key words: deep-water tardigrades, Dipodarctus subterraneus, Tanarctus ramazzottii, abundance, distribution, Black Sea.

Ticks of the Genus Rhipicephalus (Acari, Ixodidae) and Their Distribution in Ukraine. Akimov I. A., Nebogatkin I. V. — Expansion of Rhipicephalus rossicus (Jakimov et Kohl-Jakimova, 1911) to the North, due to all its developmental stages have wide range of feeders (from amphibians to mammals) in the new man-made environmental conditions in the steppe and wood-and-steppe of Ukraine and the warming of climate (especially warm winters), is observed. The northern boundary of R. rossicus distribution lies in Vinnytsya, Kyiv, Poltava and Sumy Regions. R. bursa (Canestrini et Fanzago, 1878) and R. sanguineus (Latreille, 1806) occur only on the shores of the Black Sea and Sea of Azov (including the Crimea). Outbreak localities of R. sanguineus are in Kerch Peninsula (Crimea) and in the Dnieper floodplain. Both R. bursa and R. sanguineus are invasive species.
Key words: Rhipicephalus rossicus, R. bursa, R. sanguineus, distribution, Ukraine.

New Vespertilio murinus (Chiroptera) Winter Records. An Indication of Expansion of the Species’ Winter Range? Godlevska L. V. — Absence of winter records, known long distance movements of parti-coloured bats ringed in North-eastern (NE) Europe, and some observations of seasonal concentrations of migrating animals had enabled to consider Vespertilio murinus, until quite recently, as a migratory species wintering outside Ukraine and NE Europe as a whole. During the last years the species had been found in the winter season (November — middle March) in Ukraine in 14 provinces and in the AR Crimea: contact records in 7 provinces, observations of autumn display song in 9 provinces and in the AR Crimea. Analysis of the data allows to assert that at present the whole territory of Ukraine belongs to the winter range of V. murinus. New winter records of V. murinus from Ukraine and other countries of NE Europe should probably be considered as an evidence of the expansion of the species’ winter range, that may be conditioned by the appearance of big massifs of rock-like structures (= multi-storey buildings) in plain regions.
Key words: Vespertilio murinus, Ukraine, NE Europe, winter range, expansion.

Avian Diversity on the Sandstone Cliff Outskirts of the Maloti/Drakensberg ‘Hot-spot’ Area in Southern Africa. Kopij G. — During the year 1999–2001, avian assemblages associated with cliffs and bushy vegetation of the Clarens Formation have been quantified by means of the line transect method (total length of transects — 107 km) in Lesotho lowlands. In total, 80 species resident in these habitats were recorded. Overall, six species were classified as dominants: Serinus canicollis, Prinia maculosa, Streptopelia senegalensis, Emberiza tahapisi, Emberiza capensis and Cisticola fulvicapilla. Together they comprised 41.4?% of all breeding pairs. Ten other species were classified as subdominants (33.9?%). Granivores were the most numerous feeding guild (31 species; 48.0?% of all pairs), followed by insectivores (27 species; 32.3?%) and frugivores (11 species; 17.4?%). The most numerous nesting guild were shrub/tree nesting birds (47.2?%). Proportions for some congereric species were calculated. The bushy vegetation is characterized by high species diversity and relatively high population densities of some species.
Key words: avian assemblages, ‘hot spot’ area, Lesotho.

Comparative Morphology of Dendrocometes paradoxus (Ciliophora, Suctorea) from two Distant Regions (Ukraine and Mexico) and Different Host Species. Dovgal I. V., Mayen-Estrada R. — Comparative analysis of Dendrocometes paradoxus Stein, 1852 cell morphology from various gammarid amphipod species in different regions of Ukraine, and those attached to several host body parts of Hyalella azteca collected in two Mexican lakes, was carried out in order to demonstrate the morphological variability, due to the hosts species or their geographical distribution. For hosts species and corporal distribution, no significant differences between the two populations were shown. As the result, it was found the suctorians common for amphipod crustaceans from Ukraine and Mexico all are conspecific and belong to D. paradoxus.
Key words: suctorians, Dendrocometes paradoxus, distribution, morphology, variability, hosts, Ukraine, Mexico.

Fourth Contribution on Late Eocene Amber Silken Fungus Beetles: a New Baltic Amber Species of Atomaria (Coleoptera, Clavicornia, Cryptophagidae). Lyubarsky G. Yu., Perkovsky E. E. — Atomaria gedanicola Lyubarsky et Perkovsky, sp. n., a new cryptophagid species from Baltic amber is described. The new species is the first recorded Eocene Atomariinae. The new species is similar to A. fuscipes Gyllenhal. It differs from the latter in having pronotum flat, posterior angles of pronotum obtuse, and antenna short. The record of A. gedanicola syninclused with Ceratopogon biting midge supports the Late Eocene age of the Baltic amber, for the Holarctic affinities of both taxa are incompatible with the paratropical climate characteristic of the Mid-European Middle Eocene.
Key words. Cryptophagidae, Atomaria, Late Eocene, Baltic amber, Russia.
