Factors of Evolution from the Positions of the System Approach (Biosphere as an Arena of Evolutionary Processes). Kovtun M. F. Ч ќбсуждаетс€ The problem of joined evolution of the life and biosphere as a global biological system. The system approach is based on P. K AnokhinТs theory of functional systems; the concepts of evolution, structure and function of biosphere are rested mainly upon V. I. VernadskyТs doctrine. It is shown that from the system approach viewpoint, the concepts of the evolution, biosphere, biotic circulation and natural selection become somewhat different; also different are appraisal and essence of other evolutionary factors. The main evolutionary factors are considered as follows: potentially unlimited number of ecological niches; heterogenity of the system; √лавными факторами эволюции представл€ютс€ следующие: потенциально неограниченное количество экологических ниш; гетерогенность системы; need of intensification of biogenic migration of atoms and expansion into biosphere resources in the biotic circulation; variability of organisms; free substance and energy; useful final result, which the system tries to receive.
Key words: evolution, biosphere, system, system approach, evolutionary factors.

Ч The bivalve mollusk Anadara inaequivalvis (Bruguie1re, 1789) is found for the first time in the Northwest part of the Sea of Azov. The find registers a final stage of settling by this species in the Azov-Black Sea basin. Distribution, ecological peculiarities of this mollusk and significance of its penetration for the local fauna are discussed.

Breeding Biology of the Fiscal Shrike, Lanius collaris (Laniidae), in a Peri-Urban Environment in Roma (Lesotho). Kopij G. Ч An urbanized population of the Fiscal Shrike was studied in a park-like residential and landscape area at the foothills of the Maloti/Drakensberg region. Studies focused on these aspects of breeding ecology which have not been previously investigated, viz. year-to-year and intra-seasonal variations in reproductive performance, breeding performance in relation to population density, and site tenacity in relation to habitat type. In addition, nest site selection and diet was also analyzed.
Key words: Lanius collaris, urbanization, breeding, diet, Lesotho, southern Africa.

Materials on Karyology of the Fire-Bellied Toad Bombina bombina and B. variegata (Amphibia, Anura, Bombinatoridae) from the Territory of Ukraine. Manilo V. V., Radchenko V. I., Reminnyj V. J. Ч Karyotypes are described for the first time and the basic morphometry measurements (centromere and humeral indexes, general length of karyotype) are presented for two species (fire-bellied and yellow-bellied toads from Ukraine). On the basic karyological parameters differences between species are shown only morphology (humeral, centromere indexes) of the fifth pair of chromosomes snd in the general length of karyotype. Chromosomal formula of Bombina bombina (Linnaeus, 1761) is 2n = 20 V + 4 SV = 24, NF = 48; B. variegata (Linnaeus, 1761): 2n = 22 V + 2 SV = 24, NF = 48. For both species the secondary constriction is located on the long shoulder of the 7-th pair of chromosomes, sexual chromosomes were not identified.
Key words: karyotype, chromosome, arm ratio, centromere index, Bombina bombina, B. variegata.

Parasitofauna of Fish of the Far East Complex Established in Reservoirs of the Southern Aral Sea. Urazbaev A. N., Kurbanova A. I. Ч The parasite fauna of fish species, acclimatized in the reservoirs of the Aral Sea basin is reviewed and compared to that in the rivers of Amur Basin and water reservoirs of China, where they were brought from. The impoverishing of their parasite fauna and its replacement by local widely distributed species is observed. The characteristic of the new-tenants parasites is given; their pathogenous forms are recorded. The information on the cycles of development of Bothriocephalus opsariichthydis Yamaguti, 1934 and on the composition of interim host in the Lower Amudarya is given.
Key words: fish parasite fauna, anthropic pressure, Southern Aral.
