Ciliates of coarse ground on the Northeastern Black Sea Coast

Azovskii A.I., Mazei Yu. A.

Free-living psammophilous ciliates were studied in six localities on the northeastern (Caucasian) coast of the Black Sea at a depth from 0 to 432 m. 168 forms were found, 139 of them were identified to the species level. Thirty-four species were described in the Black Sea for the first time. A list of species and brief descriptions of some species are given. The highest diversity of ciliates was found in heterogeneous sands at a depth of 3-10 m, the lowest one - in unstable sands of the tidal zone and in silt deeper than 25 m. No ciliates were found in the zone enriched with H

Landscape chorology of collembola on Taimyr peninsula. 1. Biotopic preferences of species

Babenko A.B.

The data of long-term studying the spatial distribution of collembolan species recorded on a latitudinal gradient from the northern taiga up to the polar deserts of Central Siberian sector of the Arctic are analyzed. The majority of Collembola species in the tundra zone is more abundant in various intrazonal communities, including both hydromorphic plant associations, and sites most supplied with heat. A limited number of the species prefers zonal communities. In other words, there are few tundra species (taking into account their biotopic preferences) in Taimyr tundras. The most specific feature of the Collembola distribution within this Arctic region is its lability manifesting itself in the natural changes of biotopic preference in a particular species along a latitudinal gradient according to the well-known rule of "station changes." The causes of frequent occurrence and a distinct display of the mechanism, smoothing the environmental conditions and permitting the Collembola species to overcome climatic boundaries in the tundra, are discussed.

New and little known crickets of the subfamily Phalangopsinae (Orthoptera, Cryllidae). 1. South Asia and Sunda Islands

Gorokhov A.V.

One new genus, three new subgenera, and eight new species of Phalangopsinae from Hindustan, Indochina, Sumatra, Java, and Sulawesi Islands are described. They differ from other similar taxa mainly in various characterisitcs of the structure of tegumen and male genitalia. These differences are desribed in detail and illustrated. Based on the type materials, some poorly studied taxa are redesribed. The taxonomic position of some other species is clarified.

Use of individual labeling of fleas (Siphonaptera) to study their dispersal by animal hosts

Kuznetsov A.A., Matrosov A.N.

Phoresia in fleas, plague microbe vectors in the Volga-Ural Sands (Russia, Kazakhstan) and on the Tay Nguyen Plateau (Vietnam) was studied by the method of individual labeling. Fleas of gerbils and rats were found can cover a distance of about 120 m for 6-7 days changing their feeders. The distance of daily movements of rodents was about 70 m. The parameters of migration of carriers and vectors in the natural sand and synanthropic tropical plague foci were revealed to be almost identical.
