  • The structure and spatial organization of the butterfly fauna
           (Lepidoptera, Rhopalocera) of the Ural Mountains
    • Abstract: Abstract The butterfly fauna of the Ural Mountains contains 233 species: Papilionidae (6 species), Pieridae (23), Lycaenidae (64), Nymphalidae (60), Satyridae (57), and Hesperiidae (23). The number of butterfly species in seven regional and 29 local faunas generally increases gradually from north to south. The mean number of species in the local butterfly faunas is 127 in the southern Urals and slightly over 50 in the Polar Urals. The arealogical structure of the fauna is determined by the distribution of species recorded in 24 meridional and 19 latitudinal groups which together result in 80 distribution patterns. Based on comparison of the local butterfly faunas of the Urals, two large, historically formed faunistic complexes are distinguished: southern and northern. Either complex contains two faunistic complexes of the second order, hypoarctic and boreal in the former, and southern boreal and subboreal in the latter. The faunas of the Kazakhstan part of the Urals form a separate subboreal semi-arid complex, whereas the extreme boreal fauna of Pay-Khoy forms an independent arctic complex.

  • Species of the genus        class="a-plus-plus">Protaphorura (Collembola:
           Onychiuridae) described on material of Yu.I. Chernov from western Taimyr
    • Abstract: Abstract Seven species of the genus Protaphorura Absolon, 1901 from the Eastern Palaearctic, viz. P. taimyrica (Martynova, 1976), P. tundricola (Martynova, 1976), P. subarctica (Martynova, 1976), P. pjasinae (Martynova, 1976), P. tschernovi (Martynova, 1976), P. borealis (Martynova, 1973), and P. cf. microcellata (Dunger, 1978), have been redescribed. The original descriptions of the majority of these species were based on Yu.I. Chernov’s material collected on Western Taimyr in the environs of the legendary “Tareya” field station. The type material and/or new collection in the environs of the type-localities were used for redescriptions. The identification key to the above species and maps of their distribution in the Palaearctic are given.

  • Ants under the conditions of an extremely hot summer
    • Abstract: Abstract Specific features of ant behavior during the extremely hot summer of 2010 were studied, as well as the aftereffects of this season on simple and complex family units of ants in 2011–2012. Simultaneous studies were carried out in southern taiga (Moscow Province, Verkhnaya Klyazma myrmecological protected area) and northern taiga (Arkhangelsk Province, Pinezhskii Nature Reserve). Ants of the genus Formica responded to the extreme heat by (1) changing their foraging patterns; (2) redesigning their nests; (3) rearranging the spatial and functional structure of the colonies. They switched to a bimodal activity pattern with maxima in the morning and in the evening and a prolonged daytime intermission. Along ant roads, there were underground pavilions with dense roofs built of conifer needles and soil. Covers of the same kind appeared over root aphid colonies. The most radical improvement was the construction of a battery of brood chambers underneath the mound. The soil excavated was used for strengthening the mound and restricting the convective heat exchange between the brood chambers and the external environment. The anthill surface was covered with a smooth crusted layer of soil and fine plant debris particles, which protected the nest from the inflow of hot air from without. A portion of the inhabitants of large nests moved to newly built extensions and auxiliary nests. It was only active, non-damaged colonies that could afford these measures and thus survive the heat with minimal loss. Depressed colonies lost the major part of their brood during this time. Furthermore, small secondary colonies that emerged as the result of destructive activity of animals also failed to reassemble due to the summer heat of 2010. The months of heat were followed by a long rainy and cool period, and the colonies that had already been depressed faced critical conditions for preparing for winter. The ants were unable to accumulate lipid reserves sufficient for spring nest heating and rearing of sexuals and workers, which turned out to be an important aftereffect of the 2010 season the following year. Two first generations of workers were absent in almost all the nests. Mass oviposition in F. aquilonia commenced only late in May 2011, whereas the flight of alates did not occur at all because alates of this species are only reared in spring. Consequently, the F. aquilonia colonies had not recovered even by the end of 2012. In F. lugubris and F. polyctena, species that rear sexuals twice a year, there was only late-season alate flight, and yet it allowed their colonies to replenish the pool of ovipositing females and restore the initial colony size by the end of 2012. Other ants, represented by Lasius niger and Myrmica rubra, also modified their nests and foraging patterns during the period of heat. M. rubra suffered the most, so that its abundance and activity remained very low in 2011 as well. Only L. niger, which remained practically unscathed by the heat, successfully completed its annual cycle in 2010. Therefore, one of the 2010 year’s results was a drastic shift in the ratio of nests built by the abovementioned species in favor of L. niger.

  • On the taxonomy of the Genus        class="a-plus-plus">Coenosia Meigen, 1826
           (Diptera, Muscidae) in the Russian Fauna, with a Description of        class="a-plus-plus">Coenosia tschernovi sp. n.
    • Abstract: Abstract Coenosia tschernovi sp. n. is described and illustrated from the Altai and Tuva republics. Coenosia nigrotincta Hennig, 1961 and C. xuei Cui et Li, 1996, are redescribed; the latter species is recorded from Russia for the first time. The new “apukaensis” group is erected for several similar Asian species. Coenosia altaica Sorokina, 2009 is considered a junior synonym of C. subgracilis Xue et Cui, 2001. Supplements to the key to the Siberian representatives of Coenosia Meigen, 1826 (Sorokina, 2009), to include new and recently found species, are given.

  • Beetles (Insecta, Coleoptera) in the arctic fauna: Communication 1. Faunal
           composition
    • Abstract: Abstract Coleoptera, the largest insect order, appears to be subordinate to Diptera in the extent of colonization of the Arctic environment. Beetles comprise about 13% of the insect fauna of the tundra zone, yet in the high latitudes several of their families retain considerable levels of species diversity and play significant cenotic roles. The present communication reviews the circumpolar beetle fauna of the Arctic. Based on original data, literature sources and museum collections, with the use of extrapolations and analogies, the taxonomic and ecological diversity patterns of the suborders, series and families of Coleoptera are distinguished, the latitude-zonal distribution and the northernmost range limits of the species are analyzed, and their adaptations and cenotic relations are characterized.

  • Two new chironomid species (Diptera, Chironomidae) from Wrangel Island
    • Abstract: Abstract Two new species from Wrangel Island, Orthocladius (Eudactylocladius) tschernovi sp. n. and O. (E.) ushakovskiensis sp. n. (Orthocladiinae), are described and illustrated from on the male adults. Orthocladius (E.) tschernovi sp. n. is closely related to O. (E.) fuscimanus (Kieffer) and O. (E.) musester Sæther, but can be distinguished from both by an almost straight transverse sternapodema, a rounded triangular superior volsella, and a long phallapodema, as well as by the presence of a subapical crista dorsalis of the gonostylus and by the shape of the anal point. Orthocladius (E.) ushakovskiensis sp. n. differs from all the known species of the subgenus in the absence of superior and inferior volsellae and in the shape of both short gonostylus and the short and wide anal point.

  • Distribution and ecology of the earthworm        class="a-plus-plus">Eisenia nordenskioldi pallida
           (Oligochaeta, Lumbricidae) dominant in southern Siberia and the Russian
           Far East
    • Abstract: Abstract A literature review and the results of re-examination of collections of the earthworm Eisenia nordenskioldi are presented. Peculiarities of the geographic and habitat distribution, as well the ecology of the diploid subspecies E. n. pallida, originally described as a non-pigmented form of E. nordenskioldi, are analyzed. E. n. pallida inhabits mainly the south of Siberia and the Russian Far East, penetrating as far northwards as the forest-tundra zone along the valleys of large rivers. It is the most abundant in the low-mountain belt in dark coniferous forests, being the dominant form of Lumbricidae there, but it is quite rare above the timberline. The range of E. n. nordenskioldi, which can be found together with E. n. pallida in the south of the territories studied, is much wider, extending further to the north and including some Arctic islands. In addition, E. n. nordenskioldi is known from the eastern parts of European Russia. Both subspecies show high levels of resistance to unfavorable abiotic factors. Differences in the latitudinal and altitudinal distribution patterns of both subspecies of E. nordenskioldi are determined by their different morpho-ecological forms.

  • Pathways of formation of the fauna of the Solovetsky Archipelago, the
           White Sea, Northwest Russia
    • Abstract: Abstract The fauna of the Solovetsky Archipelago represents an extremely depleted and reduced variant of the continental northern boreal one. The level of its depletion roughly corresponds to the latitudinal shift by one or two biomes, that is, by the number of species it is comparable to the mainland concrete faunas of the forested or hypoarctic tundra. Only very few arctic species, let alone more southern (nemoral) faunal elements, occur on the archipelago. The compositions of the basic fauna groups and their dominant species are determined there by three main factors: a wide distribution of intrazonal ecosystems (coastal wastelands and grasslands, birch sparse forests, peat bogs), limited living space, and extreme climatic conditions. Among the dominants are eurytopic polyzonal and, to a lesser degree, hypoarctic species. The isolation of the Solovetsky Islands is no significant barrier to the dispersal of numerous animal species, but these islands form a highly specific environment that strongly prevents the invasion of new species lacking relevant preadaptations to the local habitat and climatic conditions. The effect of “density compensation” of lower taxonomic diversity is revealed on the archipelago in many taxa, the range of abundant species being able to vary considerably in time depending on the climatic conditions. The Solovetsky Islands’ fauna is continental by origin, having been mainly formed in the Late Pleistocene and Early Holocene (∼9–10 ka before the present).

  • The structure and seasonal dynamics of myriapods (Chilopoda and Diplopoda)
           in the southern taiga of the Perm Cis-Urals Region
    • Abstract: Abstract The spatial and temporal dynamics of myriapod assemblages in the Preduralye protected area (Kishertskii District, Perm Territory) is studied. There are 10 species found, which have been assigned to three landscape groups (floodplain, terrace, and forest species) and four phenological groups (spring-summer, summer, latesummerautumn, and autumn species). Seasonally stable differences are found between myriapod assemblages of riverine biotopes (floodplain and fluvial terraces) and those of drainage divides (hillsides and uplands). The structure of the myriapod assemblage changes thrice in the course of the growing season. The spring-early-summer pattern develops without drastic transformations into the summer one, which is characterized by maximum diversity. The establishment of the autumn pattern is marked ubiquitously by stronger dominance of two eurybiont species, a lithobiomorph centipede Lithobius curtipes (C.L. Koch, 1847) and a millipede Altajosoma golovatchi (Shear, 1990), which is accompanied by the simplification of the species structure and the reduction of diversity of taxocenes. The horizons of the application of the landscape-phenological classification of species are briefly discussed, as well as the consideration of phenological patterns during invertebrate surveys.

           Plateau, with a description of        class="a-plus-plus">Dactylolabis tschernovi sp. n.
           
    • Abstract: Abstract The first data are presented on the tipuloid dipterans from the Putorana Plateau, the Central Siberian Plateau: the crane-flies, Tipula (Arctotipula) oklandi Al., Tipula (Pterelachisus) tundrensis stackelbergiana Lack., Tipula (Vestiplex) arctica Curt., and Tipula (Yamatotipula) lionota Holm.; and the limoniids, Dactylolabis (Dactylolabis) novaezemblae (Al.) and Dactylolabis (Dactylolabis) tschernovi sp. n. A new species, Dactylolabis (D.) tschernovi sp. n., is described from the adult males and females. The male of the new species is very similar to those of Dactylolabis (Dactylolabis) carbonaria Sav. and Dactylolabis (Dactylolabis) satanas Sav. but can be distinguished from the former by the presence of a distinct throat, by the coloration of the head, femora, tibiae, and abdominal segments, as well as by the spear-shaped interbase of the hypopygium; and from the latter species, by the fully developed wings and by the absence of large spines at the base of the interbases.

  • Grass-fly larvae (Diptera, Chloropidae): Diversity, habitats, and feeding
           specializations
    • Abstract: Abstract The fly family Chloropidae belongs to the higher Diptera series Acalyptratae. It is distributed worldwide and globally comprises 200 genera and about 3000 species in 4 subfamilies: Oscinellinae, Siphonellopsinae, Rhodesiellinae, and Chloropinae. In the fossil record, Chloropidae are known since the Oligocene, with 2 genera found in Baltic amber: one extinct, the other recent. The family includes several important agricultural pests (frit flies, gout flies, Meromyza, seed pests) which injure corn. The feeding preferences of chloropid larvae vary strongly: there are saprophages in the broad sense, true phytophages using both woody and grassy plants (mainly monocots), predators on egg masses of insects and spiders, as well as on scale insects and aphids, and ectoparasites of frogs. Among the 100 families of monocots (Liliopsida), only 11 include species serving as food plants for chloropid larvae. The greatest diversity of habitats and feeding types is observed in the subfamily Oscinellinae. The most advanced subfamily Chloropinae includes mostly phytophagous larvae. A possible scenario of ecological evolution within the family is briefly discussed.

  • Antlions (Neuroptera, Myrmeleontidae) from ornithological traps on the
           Curonian Spit: A three-species community containing a new species
    • Abstract: Abstract A mixed antlion community is recorded at the “Fringilla” Research Station, “Rybachii” Biological Station, Curonian Spit, Baltic Sea, Kaliningrad Province, Russia; the adults were captured using ornithological traps and the larvae were found on sand dunes around. The ratio of the larval numbers in the mixed colonies of Myrmeleon tschernovi sp. n., Myrmeleon formicarius L., and Euroleon nostras (Geoffr.) is 100: 3: 2. The new species is described, the other two are recorded in Kaliningrad Province for the first time. Morphologically, Myrmeleon tschernovi sp. n. is similar to Myrmeleon bore (Tjed.), being its neighbor in the Baltic Region and occupying its econiche. The most characteristic distinctions between these species are found in the male genitalia and in the larval head chaetotaxy and color pattern.

  • A new species of the genus        class="a-plus-plus">Falconius Bolívar, 1898
           (Orthoptera: Tetrigidae, Scelimeninae) from Vietnam
    • Abstract: Abstract Falconius tschernovi sp. n. is described from Vietnam. The new species is closely related to F. dubius Günther, 1938 from Malaysia (Borneo) and F. guangxiensis Zheng et Jiang, 1997 from China (Guangxi Zhuang Autonomous Region), but differs from both in the presence of two pairs of additional lateral keels on the disc of the pronotum, in the armament of the fore femur, in the narrow hind femur, and in the coloration of the hind tibia.

  • Two New species of the dipteran genus        class="a-plus-plus">Dolichopus Latreille (Diptera,
           Dolichopodidae) from Siberia and Mongolia
    • Abstract: Abstract Two new species of the genus Dolichopus Latreille (Diptera, Dolichopodidae) are described from Mongolia and Siberia. Dolichopus tschernovi Negrobov, Barkalov et Selivanova, sp. n. is similar to Dolichopus bayaticus Negrobov, 1976, but differs in the presence of one seta on the hind metatarsus, the shorter 3rd antennal segment, and in the structure of the hypopygium. Dolichopus lenensis Negrobov, Barkalov et Selivanova, sp. n. resembles Dolichopus setitarsis Negrobov et Barkalov, 1977, but differs in the slightly widened 2nd–4th segments of the middle tarsus, in the presence of one seta on the hind metatarsus, and in the structure of the hypopygium. Drawings of the antennae, tarsi, and hypopygium of the new species are given. The holotypes of the new species are deposited in the Zoological Institute, the Russian Academy of Sciences (St. Petersburg).

  • Cold hardiness and geographic distribution of earthworms (Oligochaeta,
           Lumbricidae, Moniligastridae)
    • Abstract: Abstract Cold hardiness of 12 species and 2 subspecies of earthworms from Northern Eurasia was studied. Supercooling temperatures, the water content and the thresholds of tolerated temperatures of worms and their cocoons were determined. The threshold values varied within −1…−35°C for worms and within −1…−196°C for cocoons. Earthworms of 4 species and 2 subspecies survived freezing. Cocoons of all species except Eisenia fetida possessed a protective dehydration mechanism which prevented their freezing. During wintering at subzero temperatures, earthworms lost up to 20% of water, cocoons up to 37%. Species of the same life form can overwinter at different phases and have different cold hardiness values. On the whole, epigeic and epi-endogeic species (except for Eisenia fetida) were more resistant to cold than endogeic ones. The following preliminary classification of earthworms according to their tolerance to negative temperatures is proposed: (1) both onthogenetic phases are tolerant; (2) only cocoons are tolerant; (3) both onthogenetic phases are intolerant. The geographic distribution of all the studied species (except for Eisenia nordenskioldi nordenskioldi) is partially or completely limited by insufficient resistance of the worms to negative temperatures. A significant cold hardiness of cocoons of most species is nonadaptive, since the worms hatched from the eggs in spring die without having enough time to reach maturity and to lay cocoons before the onset of subzero temperatures. Only 3 species (Eisenia nordenskioldi nordenskioldi, Eisenia atlavinyteae, and Dendrobaena octaedra) can live in permafrost regions; this is the main reason for a drastically reduced diversity of earthworm assemblages in eastern Siberia except for its southern, mountain parts. In general, the reasons for the impoverishment lie in the modern climatic conditions correlated with the ecophysiological capacities of earthworms.

  • Distribution of the spider mite        class="a-plus-plus">Tetranychus urticae Koch
           (Acarina, Tetranychidae) over the leaves of different cucumber cultivars
    • Abstract: Abstract Distribution of spider mites over cucumber leaves is determined by the topical trophic specialization of the pest manifested in preference for the central leaf zone. After artificial infestation of leaves with female mites, the modified aggregated distribution of the pest depended on the number of mites on the leaf, the morpho-physiological state and stage of development of the leaf and the whole plant, and the cucumber cultivar.
