Revision of<Emphasis Type="Italic">Cheliderpeton vranyi</Emphasis><Emphasis Type="SmallCaps">Fritsch</Emphasis>, 1877 (Amphibia,Temnospondyli) from the Lower Permian of Bohemia (Czech Republic)

The temnospondylCheliderpeton vranyi Fritsch, 1877 from the Lower Permian Ruprechtice horizon (Rotliegend) of the Intrasudetic Basin (Bohemia, Czech Republic) is redescribed. Many features of the skeleton permit a new understanding of the type species and consequently of the genus. Diagnostic characters are the narrow and round-tipped snout, straight to convex outline of the skull roof, narrow and long otic notch, posteriorly expanded quadratojugal, and the relatively wide and short rhombic interclavicle. The ilium with a short, expanded dorsal branch and the missing contact of nasal/maxilla are features shared with the related Upper PermianIntasuchus from Russia and the Eryopidae.Actinodon germanicus is a junior synonym ofCheliderpeton vranyi.

An illustrated key to Rophites species and an annotated list of 9 species from Russia and adjacent territories are given. Rophites clypealis stepposus subsp. n. and the female of R. schoenitzeri Dubitzky, 2004 are described. Lectotypes of Rhophites caucasicus Morawitz, 1876 and Rh. mandibularis Morawitz, 1891 are designated. Rophites algirus is recorded for the first time from Armenia; R. caucasicus, from Azerbaijan; R. clypealis, from Bulgaria, Russia, and Kazakhstan; R. foveolatus, from Georgia; R. quinquespinosus, from Armenia and Uzbekistan; R. schoenitzeri, from Azerbaijan and Iran.     

The subspecies of <Emphasis Type="Italic">Chrysolina limbata</Emphasis> (Coleoptera,Chrysomelidae)

Examination of 1492 specimens of Ch. limbata (Fabricius, 1775) from the entire distribution range resulted in the discrimination of six subspecies: limbata (West Europe excluding the Apennine Peninsula, the Crimea, north and south of European Russia, the Great Caucasus, Northern Kazakhstan, and southern West Siberia), discipennis (Ménétriés, 1848) (southeast of European Russia, Western Kazakhstan), hochhuthii (Suffrian, 1851) (south of East Siberia, Eastern Kazakhstan, Mongolia, Northern China), luigionii (Depoli, 1936) (the Apennines, the Alps, Herzegovina, the Mediterranean coast of France); russiella ssp. n. (deciduous forests, forest-steppe and steppe of European Russia and Ukraine); volodi ssp. n. (alpine regions of the Lesser Caucasus and eastern Turkey). Ch. limbata findelii (Suffrian, 1851) is a new junior synonym of Ch. limbata limbata.     

Role of cooperative H(+)/e(-) linkage (redox bohr effect) at heme a/Cu(A) and heme a(3)/Cu(B) in the proton pump of cytochrome c oxidase

It is a pleasure to contribute to the special issue published in honor of Vladimir Skulachev, a distinguished scientist who greatly contributes to maintain a high standard of biochemical research in Russia. A more particular reason can be found in his work (Artzabanov, V. Y., Konstantinov, A. A., and Skulachev, V. P. (1978) FEBS Lett., 87, 180–185), where observations anticipating some ideas presented in my article were reported. Cytochrome c oxidase exhibits protonmotive, redox linked allosteric cooperativity. Experimental observations on soluble bovine cytochrome c oxidase are presented showing that oxido-reduction of heme a/Cu_A and heme a ₃/Cu_B is linked to deprotonation/protonation of two clusters of protolytic groups, A₁ and A₂, respectively. This cooperative linkage (redox Bohr effect) results in the translocation of 1 H⁺/oxidase molecule upon oxido-reduction of heme a/Cu_A and heme a ₃/Cu_B, respectively. Results on liposome-reconstituted oxidase show that upon oxidation of heme a/Cu_A and heme a ₃/Cu_B protons from A₁ and A₂ are released in the outer aqueous phase. A₁ but not A₂ appears to take up protons from the inner aqueous space upon reduction of the respective redox center. A cooperative model is presented in which the A₁ and A₂ clusters, operating in close sequence, constitute together the gate of the proton pump in cytochrome c oxidase.Translated from Biokhimiya, Vol. 70, No. 2, 2005, pp. 220–230.Original Russian Text Copyright © 2005 by Papa.This revised version was published online in April 2005 with corrections to the post codes.     

Molecular variation in Galdieria sulphuraria (Galdieri) Merola and its bearing on taxonomy

Cyanidium caldarium, Cyanidioschyzon merolae and Galdieria sulphuraria are three unicellular algae characteristic, of acid thermal environments. Recently, on the basis of morphological characters, three new species of Galdieria (G. partita, G. daedala, G. maxima ) isolated from acid-thermal springs in Russia have been instituted. A selected region of rbcL and the sequence of the intergenic spacer between the rbcL and rbcS have been amplified and sequenced from different Galdieria species and strains, in order to define molecular relationship among these interesting algae. The obtained cladogram shows that Cyanidium caldarium and Cyanidioschyzon merolae form a sister group which, in turn, is in a sister group relationship with Galdieria. This last genus is divided in two clades, one of which includes G. sulphuraria accessions from Naples (Italy), California, and Yellowstone and the other one includes G. sulphuraria accessions from Java (Indonesia) and from the Russian species. These results support the status of the genus Galdieria and suggest that G. daedala, G. maxima and G. partita are three very similar strains of G. sulphuraria; the rbcL variation within Galdieria accessions has a pattern which is broadly connected to the geographial distribution. The data obtained from the intergenic rbcL-rbcS spacer partly confirm those from the rbcL analysis.     

Differences in Borrelia infections in adult Ixodes persulcatus and Ixodes ricinus ticks (Acari: Ixodidae) in populations of north-western Russia

Dark-field microscopy was used to determine the number of Borrelia spirochetes in 630 standard preparations obtained from adult ixodid ticks (344 Ixodes persulcatus and 286 I. ricinus) collected in 1989-92 in the Leningrad region of Russia. The average numbers of Borrelia in I. persulcatus and I. ricinus preparations were 34.7 and 23.3 per 100 microscopic fields, respectively. The maximal individual values registered each year for ticks of both species were several hundred times greater than the minimal values. Ticks carrying relatively small numbers of Borrelia generally predominated. Proportions of more heavily infected ticks varied considerably from year to year. These parameters were significantly higher in foci with predominance of I. persulcatus ticks. As a consequence, risk to acquire Lyme borreliosis in such foci is considered greater than in foci where I. ricinus predominates.     

New species of the genus <Emphasis Type="Italic">Macclintockia</Emphasis> (Angiosperms) from the Campanian of the Ugol’naya Bay (Northeastern Russia)

New species of angiosperms are described as members of the genus Macclintockia from the Ugol’naya Bay area, in northeastern Russia: M. barykovensis Moiseeva, sp. nov., M. gigantea Moiseeva, sp. nov., and M. terranea Moiseeva et Herman, sp. nov. Leaves of this genus are considerably variable, which hampers differentiation between particular species. The study of new material has allowed the author to trace the morphological variability of these species and revised on this ground the composition of the species M. ochotica Vachr. et Herman and M. beringiana Herman. The composition of Macclintockia is discussed, as well as its occurrence during the Late Cretaceous.     

On the knowledge of the geographic variation of the satyrid <Emphasis Type="Italic">Oeneis jutta</Emphasis> (Hübner, [1806]) (Lepidoptera,Satyridae) in the Northeast of European Russia

Analysis of the geographic variation of external characters of the satyrid Oeneis jutta (Lepidoptera, Satyridae) in the northeast of European Russia was carried out. Variation of the forewing length, diameter of eyespots, their total number and frequency of occurrence on the upper side of wings were studied. The regional populations of Oe. jutta were shown to lack significant differences in the characters studied. Besides the similarity of external characters, similar ecological traits also suggest that Oe. jutta populations from the northeast of European Russia belong to the nominative subspecies. The probable history of distribution of Oe. jutta across Europe also suggests that the nominative subspecies occurs in the territory studied.     

Backswimmers (Heteroptera,Notonectidae) of the Kabardino-Balkarian Republic (Central Caucasus)

Three species of backswimmers (Heteroptera, Notonectidae) are recorded from Kabardino-Balkaria: Notonecta glauca Linnaeus, N. viridis Delcourt, and Anisops sardeus Herrich-Schaeffer, the latter species being new to the fauna of Russia.     

Genus <Emphasis Type="Italic">Chelonus</Emphasis> Jurine (Hymenoptera,Braconidae, Cheloninae) in the fauna of Russia and adjacent territories. <Emphasis Type="Italic">Ch. olgae</Emphasis> Kok. species-group

The Ch. olgae species-group is established in the genus Chelonus characterized by the metasomal carapace narrowing towards the apex (much more strongly than towards the base) and not or weakly incurved. This group is analogous to the M. retusus group of the closely related genus Microchelonus, although some differences in the carapace structure emphasize parallel development of these morphological features in the two genera. New species are described as follows: Ch. borisi sp. n. (Russia: Leningrad Prov.), Ch. cardui sp. n. (Russia: Voronezh Prov.; Moldova), Ch. kokoujevi sp. n. (Russia: Belgorod and Chelyabinsk provinces), Ch. speijeri sp. n. (Spain), Ch. ubsunuricus sp. n. (Russia: Tuva), and Ch. yurii sp. n. (Kazakhstan). Chelonus subannulatus Abdinbekova, 1971 is synonymised with Ch. submuticus Wesmael, 1835(syn. n.).

A new species of the genus <Emphasis Type="Italic">Siteroptes</Emphasis> (Acari,Heterostigmata, Pygmephoridae) from European Russia

A new species, Siteroptes longisetissimus Khaustov et Ermilov sp. n., is described from European Russia (Nizhnii Novgorod Province). The new species differs from all the congeners in the presence of very small oval stigmata and in the absence of setae v on femora III and IV. A key to families of the superfamily Pygmephoroidea is provided.     

Phytoplankton composition of the Kandalaksha Gulf, Russian White Sea: Dinophysis and lipophilic toxins in the blue mussel (Mytilus edulis)

Dinophysis acuminata and D. norvegica were observed in plankton net samples during the summer of 2002 from the Kandalaksha Gulf in the White Sea (North European Russia). Prorocentrum lima was found as an epiphyte on subtidal macroalgae in August, but not observed in plankton net samples. Protein phosphatase 2A (PP2A) inhibition measured 127.8 ng OA-equivalent/g of mussel (Mytilus edulis) hepatopancreas from samples collected a few days after when Dinophysis was recorded at a density of 1550 cells L⁻¹. Liquid chromatography–mass spectrometry confirmed presence of several classes of lipophilic shellfish toxins associated with Dinophysis spp. in the mussels including okadaic acid, dinophysistoxin-1, pectenotoxins and yessotoxins. No azaspiracid was detected. This represents the first identification of phycotoxicity in the White Sea.     

Hippotraginae (Bovidae,Artiodactyla, Mammalia) from the Late Miocene of Tuva

Fossil remains of Late Miocene (Baode, NMU10-NMU11) horse antelopes from Tuva (Russia) are described, including Tragoreas sp., Protoryx tuvaensis sp. nov. from the Taralyk Cher locality and Quirliqnoria sp. from the Kholu locality. A new species, Protoryx tuvaensis Dmitrieva et Serdyuk, is described. These taxa compose a Late Miocene antelope assemblage of a new eastern geographical point (Russia, Tuva, Baode, NMU10-MN11).     

Reinstatement of the genus Paralona Sramek-Husek et al., 1962, and assessment of morphological variability in the Paralona pigra-group (Anomopoda: Chydoridae)

We studied the morphology of some members of the Chydorus piger-group, using populations from Karelia (Russia), France, Germany, the Azores, Magadan (East Siberia), Newfoundland (Canada), Venezuela, Zambia, and Bolivia, and move Chydorus piger Sars, 1861 to the genus Paralona Sramek-Husek et al., 1962, which we redefine using traditional characters (first antenna with subapical and apical esthetascs, second antenna with only six setae, ventral valve rim fully setulated with setae in marginal position except between anterior bend and well-developed anterior flange), as well as structural features of the trunk limbs, especially 1 and 2. Chydorus and Pleuroxus are the nearest relatives of Paralona.The genus presently contains only the species P. pigra (Sars, 1861). This, however, shows considerable morphological variation and might therefore be composed of several related taxa, in need of a closer definition.     

Unravelling the systematics of Nodularia (Bivalvia,Unionidae) species from eastern Russia

Conservation efforts have been hindered by data deficient conservation status assessments, especially due to taxonomic problems. This is especially true for many eastern Russian species of freshwater mussels, where distinct classification systems have complicated their delimitation and identification. Nodularia is a widespread eastern Asian freshwater mussel genus, present from Vietnam in the south to the Magadan region in eastern Russia in the north. The number of recognized species in the genus Nodularia in eastern Russia has been inflated over the last several decades due to the use of a typological species concept, the so-called 'Comparatory Method'. This method uses a single diagnostic character for species delimitation, i.e., the arc of maximal convexity of the shell's outline. Using this classification system, 10 species were recognized for far eastern Russia under the genus Nodularia Conrad, 1853, divided into three subgenera: Nodularia s. str., Amurunio and Magadaninaia. Since it is not supported by any other classification methods, the current comparatory classification is rejected by many Russian and international scientists, who only recognize a single species for that region, i.e., Nodularia douglasiae. Therefore, the aim of the present study is to clarify the taxonomy and systematics of the Nodularia genus in far eastern Russia and adjacent territories, using a multiple dataset approach that combines distribution with detailed conchological and anatomical analyses with morphometry and COI barcoding molecular techniques. All analyses performed in this study support the existence of a single Nodularia species in eastern Russia, i.e., N. douglasiae.     

First record of a brachiopod (Brachiopoda: Terebrataliidae) in the fouling of hydrotechnical installations in Peter the Great Bay,Sea of Japan

Large mature individuals of the brachiopod Coptothyris adamsi Davidson, 1871 were found in the fouling of a pier in Koz’mina Bight (Nakhodka Bay, Peter the Great Bay, Sea of Japan) in September 2006. The population density of the brachiopod in the fouling reached 100 specimens/m² and greatly exceeded the density of this species in benthic communities (4 specimens/m²). This is the first record of a brachiopod on anthropogenic substrates in the Far-Eastern seas of Russia. It is of particular interest because (1) C. adamsi is listed in the Red Book of Russia and (2) construction of an international oil terminal is planned for Koz’mina Bight. The brachiopod population can be used to monitor environmental conditions during the construction and further functioning of the oil terminal in Koz’mina Bight.     

Species of the genus <Emphasis Type="Italic">Salda</Emphasis> F. (Heteroptera,Saldidae) of the fauna of Russia and adjacent territories

Material of the genus Salda F. from Russia and adjacent territories, deposited in the Zoological Institute of the Russian Academy of Sciences (St. Petersburg), is revised. Data on the distribution of eight species (S. henschii Reut., S. kiritshenkoi Cobben, S. littoralis L., S. micans Jak., S. morio Zett., S. muelleri Gmel., S. sahlbergi Reut., S. splendens Jak.) with dotted maps and a key to the species are given.
