Sprigtails (Collembola) from the Crimea

Kaprus I. Ya., Pomorski R. Ya., Skariynski D., Potapov M.B.

The collembolan fauna of the South Coast, mountain and steppe areas of the Crimea were studied. The samples were taken in litter and epiphytic communities of forests, plateau ("yaila"), plain steppe, coastal xerophytic bushes, beaches, and on banks of freshwater bodies. The list of springtails from the Crimea (141 species) was amplified with 100 ones; nine species were new. The widespread species formed more than a half of the total fauna, twelve species are endemic ones. The main quantitative indices for the early-autumn collembolan ро

Structure of collembolan fauna in the Arctic

Babenko A.B.

425 species of Collembola are known for certain from regions to the north of the tree line. They comprises about 6% of the world diversity of this taxon. As much as 60% of families and 20% of genera of the world fauna are present there. Despite the vast ranges of most of species, distributional patterns of Collembola in the Arctic follows those characteristic of traditional biogeographical subdivisions in the northern Holarctic. The higher similarity of regional faunas of the group in the Arctic as compared to that in faunas of the boreal forest zone could be explained by ecological causes rather than by the history of the faunas. The changes observed in the faunal structure at the northern border of boreal forests are less fundamental in Collembola than in other taxa of terrestrial Arthropods. This fact reflects a high potential of this group and pre-adaptation of the Holarctic fauna to the Arctic environment.

The species structure of community and abundance of heterotrophic flagellates in small freshwater bodies

Mazei Yu. A., Tikhonenkov D.V., Myl'nikov A.P.

The abundance, biomass, size, and species structure of a heterotrophic flagellate community were studied in small water bodies in June-July of 2003 (Yaroslavl oblast). The species diversity of flagellates was mainly represented by 41 species. Three groups - Chrysomonads, Bodonids, and Cercomonads-predominated with respect to their biomass and abundance. In different biotopes, the population of heterotrophic flagellates ranged from 40 to 41700 ind./cm

The stonefly fauna in the central Sikhote-Alin mountains with description of new species

Potikha E.V., Zhil'tsova L.A.

The data on biodiversity of stoneflies in the central Sikhote-Alin mountains are summarized. Sixty species of 30 genera and 8 families are recorded. The geographical distribution, emergence periods, and the abundance of stoneflies for every species are analyzed. Palaearctic (22) and eastpalaearctic (20) species predominate in the central Sikhote-Alin fauna over Pacific species (8); circumpolar, transpalaearctic, and amphiberingian species are rare. The new species,
