A new express-method for study of integumental organs in copepods

Alekseev V.R., Naumova E. Yu.

A new method for preparation and analysis of integumental microstractures in lower crustaceans is suggested. This method allows one to accelerate and simplify preparation and painting of samples for microscopy. The possibility to apply this technique for pore signature analyses from the example of studying two calanids

A review of stoneflies of the family Perlodidae (Plecoptera) in the fauna of Russia and adjacent countries

Zhil'tsova L.A.

Fifty-two species and subspecies of the family Perlodidae were described in the fauna of Russia and adjacent countries (within the former USRR). The greatest number of species (19) belongs to the genus

Grassflies (Diptera, Chloropidae) in the northern Palaearctic

Narchuk E.P.

The Chloropidae fauna of the northern part of the Palaearctic region was analyzed. Fifty-six species of this family was found in the region - the greatest number of species is known from northern Fennoscandia. Ten species of the family occur in the tundra zone - four species of the subfamily Oscinellinae and 6 species of Chloropinae subfamily. One species of Chloropinae and six Oscinellinae species dwell in some localities of the tundra zone. Only one species has saprophagous larvae, twelve and four species have phytophagous and carnivorous ones, respectively. Most phytophagous species are associated with Cyperacea plants, the others, with Poaceae ones. Chloropidae were not found within polar deserts and arctic tundra. Holarctic and transpalaearctic species are widespread in tundra landscapes. No species characteristic only of arctic regions was found. Three species may dwell in zonal tundra habitats; the rest ones prefer intrazonal habitats: bogs, nival and zoogenic meadows.

Individuality of alarm calls in the spotted suslik

Volodin I.A.

The structure of alarm calls in spotted susliks is very simple. They are practically flat in frequency modulation, their duration is weakly variable, and they do not consist of nonlinear phenomena. A hypothesis that even such a simple vocal structure provides the potential of encoding the individuality of a caller with high reliability is tested. Alarm calls were recorded from animals of known sex and age in June-August, 2001-2002 in Zaraiskii district of Moscow region. In total, 892 sounds from 19 individuals were analyzed by 15 parameters. Discriminant analysis of 389 sounds (29-30 sounds from each of 13 individuals) showed 95.9% of the correct assignment to an individual (crossvalidation 95.4%) that is much higher than random values (7.7%). Separately for 7 males and 6 females, the values of correct assignment were 99.0 and 98.9%, respectively. However, the percentage of correct assignment to sex of 71.5%

relations between tribes of the family Attelabidae were reconstructed. The independence of the subfamily Apoderinae is confirmed. The most important in the cladogram obtained is a serial branching of tribes from the main stem that shows their isolation from each other and a consecutive purchase of apomorphies.

Structure and role of larva anal papillae in Diptera (Insecta)

Krivosheina M.G.

Several morphological groups of papillae were distinguished in the dipterous families Ptychopteridae, Culi-cidae, Tipulidae, Limoniidae, Blephariceridae, Chironomidae, Simuliidae, Axymyiidae, and Svrphidae: anal papillae without trachea being tubercles of rectum; anal papillae with trachea; terminal papillae containing tra-cheal branches and not connected with rectum; abdominal papillae with trachea. Papillae of the first type are suggested to fulfil mainly the osmoregulator function; other their groups may take part in the process of breathing. No relations between the degree of developing the tracheal system of larvae and the presence or absence of papillae of different types were found. Probably, the process of breathing in Diptera larvae may proceed by several ways, and breathing organs may replace or supplement each other depending on environmental conditions.

Vertical distribution of collembolan communities in chernozems of the "Privolzhskaya Lesostep" Reserve

Shveenkova Yu. B.

In the profile of chernozem (a Calamagrostis meadow), collembolan communities were very dispersed, and zones of hemi- and euedaphic species concentration were separated. Along the soil profile, the total abundance, species richness, and population of some collembolan species decreased irregularly. The second peak of their number was recorded at a depth of 20-30 cm. In less xelophilic biotopes, a relative abundance of collembolans increased in the litter and decreased in the soil. These processes were accompanied by the changes in ecological specialization of the collembolan community. Steppe biotopes were characterized by the greater relative abundance of collembolans in soil layers and their even distribution along soil profile. In forest, collembolans concentrated in the litter. In the steppe - forest ecotone, sharp changes in the vertical distribution of collembolans were observed in soil under shrubs.
