Abstract Twelve species are recorded for the first time from the Altai Republic, Russia, based on the materials collected by authors in the vicinity of the northern part of Lake Teletskoye in the southern taiga of Western Siberia. Nabis (Dolichonabis) americolimbatus (Carayon, 1961) is recorded for the first time for the Western Siberia. Seven species, Pachycoleus pusillimus (J. Sahlberg, 1870) (and family Dipsocoridae Dohrn, 1859), Saldula orthochila (Fieber, 1859), Xylocoris cursitans (Fallén, 1807), Acalypta carinata (Panzer, 1806), Empicoris vagabundus (Linnaeus, 1758), Drymus brunneus (R.F. Sahlberg, 1848), Scolopostethus thomsoni Reuter, 1875 are recorded for the first time from the Russian Altai. Four species are recorded for the first time from the Altai Republic – Phytocoris longipennis Flor, 1861, Nysius helveticus (Herrich-Shaeffer, 1850), Kleidocerys resedae resedae (Panzer, 1797), Cymus glandicolor Hahn, 1832. For each species the general distribution, the detailed distribution in the adjacent territories of Siberia, and the data on the biotopic confinement are provided. In addition, the data on the abundance and ecology of some other rare species are provided. Key words: Insects, hemipterans, West Siberia, Altai Republic, Lake Teletskoye, new records, distribution, ecology. Introduction Currently, about 350 heteropteran species are known from the Altai Republic. Most of them are recorded from steppe and semi-desert regions of southern Altai. The bugs fauna of northern taiga of mountain Altai has been less studied then the southern regions, and counts, approximately, two times less species. The data on the taxonomic composition of bugs of the Russian Altai and of Asian part of Russia as a whole is presented in the catalog by Vinokurov et al. (2010). Faunistic data on the Heteroptera of the Altai of eastern Ecologica Montenegrina, 40, 2021, 164-175 GOLUB ET AL. Kazakhstan were provided by Asanova (1974, 1975, 1996) and Esenbekova (2013). A considerable volume of information on the species composition of bugs of the Mongolian Altai was published by Kerzhner (1974), Kiritshenko & Kerzhner (1974) and others in their studies of Heteroptera of Mongolia. Present paper provides the first records of 12 species of terrestrial Heteroptera based on the materials collected by V.B. Golub, E.V. Aksenenko, V.A. Soboleva and N.V. Golub in the northern part of the Altai Republic in the vicinity of Artybash village in 2019 (Fig.1). The general distribution of the listed species is given according to the Catalogue of Palaearctic Heteroptera (1995–2006) with additions (Catalogue of Palaearctic Heteroptera, Supplement 2013). More detailed information on the distribution of the discussed species in Western Siberia and closest regions of Eastern Siberia are cited from the Catalogue of Hemiptera of the Asian part of Russia (Vinokurov et al. 2010). Furthermore, additional information on the distribution of these species in Siberia is given based on data published later than the mentioned Catalogues (Galich & Ivanov 2012; Ivanov 2015; Vinokurov & Golub 2016; etc.). The nomenclature and order of taxa arrangement correspond to those from the both mentioned Catalogues. Material and methods The material listed in this paper was collected in July-August, 2019 in the vicinity of Artybash village and in the vicinity of field station “Teletskaya” of the Institute of Systematics and Ecology of Animals of the Siberian Branch of the Russian Academy of Sciences at the northern part of the Lake Teletskoye. Figure 1. Taiga on the slopes of the Altai mountains at northern part of the Lake Teletskoye (Photo by V.A. Soboleva). The material collecting was carried out using the traditional methods: by entomological net, hand (manual) collecting from grassy and tree-shrub vegetation, soil, mosses, at the roots of plants, and by mosses analyzing (Golub et al. 2012). The species determination was verified using the materials of the Zoological Institute of the Russian Academy of Sciences, St. Petersburg (ZIN). The collected and studied material is stored in the collections of the Department of Zoology and Parasitology of Voronezh State University, Voronezh and the ZIN.

Sahlberg, 1870) Fig. 2 Material. Altai Republic, the vicinity of Artybash village: a swampy area on the margin of the forest, below the waterfall on the Oyrok (Third) River, 51º47'30.7" N, 87º19'8.2" E, 492 m a. s. l., on wet mosses, 30.07.2019 (V. Golub), 1 male. Distribution. European–West Siberian species. Northern and Central Europe and the mountains of Southern Europe. In European part of Russia it was recorded only from Karelia, Voronezh and Belgorod Provinces (Prokin, 2008); in Asian part it was recorded only from Tyumen Province (Ivanov 2015). This family was recorded for the first time from the Altai Republic and Altai as a whole. Ecology. The species occurs in swampy habitats. In Western Europe, it almost always collected on Sphagnum mosses (Heiss & Péricart 2007). In the European part of Russia (Voronezh Province) (Golub 2004), and in Western Siberia (Tyumen Province) (Ivanov 2015) the species was also collected on wet or dried mosses, non Sphagnum. In the vicinity of Artybash village a single specimen was collected on mosses in a small swampy meadow at the edge of the forest, however, Sphagnum was not found at the collection point. Note. Until 2015, the species was known only from Europe. The previous finding of the species in Siberia (Ivanov 2015) and our record from the Altai Mountains are the evidences of its wide range of the boreal type. Figure 2.

[True-bugs (Hemiptera: Heteroptera) overwintering in a forest litter in different types of forest near Turawa and Szczedrzyk (Opole voivodship ]. Data on true- bugs (Hemiptera: Heteroptera) overwintering in the forest litter are still scarce and insufficient. Specimens for the study have been collected from October 2011 to April 2013, during the accumulation of a litter and a high probability of bugs overwintering. As a result, new localities for 19 species of Heteroptera in Turawa and Szczedrzyk (Opole voivodship) were presented. During the studies, two specimens of a bug species new to the Polish fauna, i.e., Scolopostethus grandis Horv. (Hemiptera: Heteroptera: Rhyparo- chromidae) were found overwintering in a litter in two localities (data already published as a separate paper; see: Lis B. & Konciała 2012); additionally, several specimens of four Heteroptera species rarely recorded in Poland were also collected. Results of this analy- sis confirm, for some species of Heteroptera, a possibility to overwinter in the larval stages, and they prove the effectiveness of searching a litter for finding an overwintering and rare insects, as well.

December 2013 / Available online: 30. January 2014 / Printed: December 2014 Abstract. Taxonomic and functional groups of heteropterans consumed by six anuran species (Bombina bombina, Pelobates fuscus, Bufo bufo, Hyla arborea, Rana arvalis, Pelophylax esculentus complex) from four localities of Kis-Balaton wetland area in western Hungary were compared. Altogether 821 heteropteran specimens belonging to 76 species were found in the diet of anurans during a 5-year study. Consumed heteropteran species diversity was highest in anurans foraging in the driest microhabitats. Functional heteropteran groups were established by ecological parameters: humidity preference and vertical distribution on vegetation. Cluster analysis indicated that heteropteran diet of anurans is habitat dependent and intraspecific similarity was low between habitats. Vertical distribution of heteropterans was more strongly correlated with similarity between anuran species. Anuran species with similar foraging strategies formed separate groups in each habitat. Results support the theory that anurans having opportunistic and non- specific feeding habits are more accustomed to unpredictable environments.

  • The Associations Between Pteridophytes and Arthropods
    FERN GAZ. 12(1) 1979 29 THE ASSOCIATIONS BETWEEN PTERIDOPHYTES AND ARTHROPODS URI GERSON The Hebrew University of Jerusalem, Faculty of Agriculture, Rehovot, Israel. ABSTRACT Insects belonging to 12 orders, as well as mites, millipedes, woodlice and tardigrades have been collected from Pterldophyta. Primitive and modern, as well as general and specialist arthropods feed on pteridophytes. Insects and mites may cause slight to severe damage, all plant parts being susceptible. Several arthropods are pests of commercial Pteridophyta, their control being difficult due to the plants' sensitivity to pesticides. Efforts are currently underway to employ insects for the biological control of bracken and water ferns. Although Pteridophyta are believed to be relatively resistant to arthropods, the evidence is inconclusive; pteridophyte phytoecdysones do not appear to inhibit insect feeders. Other secondary compounds of preridophytes, like prunasine, may have a more important role in protecting bracken from herbivores. Several chemicals capable of adversely affecting insects have been extracted from Pteridophyta. The litter of pteridophytes provides a humid habitat for various parasitic arthropods, like the sheep tick. Ants often abound on pteridophytes (especially in the tropics) and may help in protecting these plants while nesting therein. These and other associations are discussed . lt is tenatively suggested that there might be a difference in the spectrum of arthropods attacking ancient as compared to modern Pteridophyta. The Osmundales, which, in contrast to other ancient pteridophytes, contain large amounts of ·phytoecdysones, are more similar to modern Pteridophyta in regard to their arthropod associates. The need for further comparative studies is advocated, with special emphasis on the tropics.

  • About the Book the Format Acknowledgments
    About the Book For more than ten years I have been working on a book on bryophyte ecology and was joined by Heinjo During, who has been very helpful in critiquing multiple versions of the chapters. But as the book progressed, the field of bryophyte ecology progressed faster. No chapter ever seemed to stay finished, hence the decision to publish online. Furthermore, rather than being a textbook, it is evolving into an encyclopedia that would be at least three volumes. Having reached the age when I could retire whenever I wanted to, I no longer needed be so concerned with the publish or perish paradigm. In keeping with the sharing nature of bryologists, and the need to educate the non-bryologists about the nature and role of bryophytes in the ecosystem, it seemed my personal goals could best be accomplished by publishing online. This has several advantages for me. I can choose the format I want, I can include lots of color images, and I can post chapters or parts of chapters as I complete them and update later if I find it important. Throughout the book I have posed questions. I have even attempt to offer hypotheses for many of these. It is my hope that these questions and hypotheses will inspire students of all ages to attempt to answer these. Some are simple and could even be done by elementary school children. Others are suitable for undergraduate projects. And some will take lifelong work or a large team of researchers around the world. Have fun with them! The Format The decision to publish Bryophyte Ecology as an ebook occurred after I had a publisher, and I am sure I have not thought of all the complexities of publishing as I complete things, rather than in the order of the planned organization.

TREWICK defining feature of the Hexapoda, as the name suggests, is six legs. Also, the body comprises a head, thorax, and abdomen. The number A of abdominal segments varies, however; there are only six in the Collembola (springtails), 9–12 in the Protura, and 10 in the Diplura, whereas in all other hexapods there are strictly 11. Insects are now regarded as comprising only those hexapods with 11 abdominal segments. Whereas crustaceans are the dominant group of arthropods in the sea, hexapods prevail on land, in numbers and biomass. Altogether, the Hexapoda constitutes the most diverse group of animals – the estimated number of described species worldwide is just over 900,000, with the beetles (order Coleoptera) comprising more than a third of these. Today, the Hexapoda is considered to contain four classes – the Insecta, and the Protura, Collembola, and Diplura. The latter three classes were formerly allied with the insect orders Archaeognatha (jumping bristletails) and Thysanura (silverfish) as the insect subclass Apterygota (‘wingless’). The Apterygota is now regarded as an artificial assemblage (Bitsch & Bitsch 2000).

  • Pleistocene Glaciations of the Se Altai, Russia, Based on Geomorphological Data and Absolute Dating of Glacial Deposits in Chagan Reference Section

Koptyuga av., 3 2Ural Federal University, Russia, 620002 Yekaterinburg, Mira str., 19 Received 25 June 2016 Accepted 9 February 2017 Abstract: Geomorphological evidence of at least two Pleistocene glacial epochsis noted within the Chagan-Uzun river basin, SE Altai. A review and analysis of all available absolute dates for reference Chagan section is presented. The highest correlation amongst all TL dates is observed for the lens of glacio-lacustrine sediments – the most suitable among glacial deposits for luminescence dating, and indicates its possible Middle Pleistocene age. IRSL dates obtained from feldspar indicate a Middle Pleistocene age of moraines already in the upper part of the section. The small number of obtained IRSL dates does not allow making geochronological reconstructions of the Pleistocene glaciations, but gives the possibility for further experiments with different variation of OSL (IRSL) techniques. Strong low temperature peak in TL signal and strong response to IR stimulation are specific regional quartz features, which could be explained by combination of short transportation distance and low number of depositional cycles for mineral grains. Available radiocarbon dates of carbonate concre- tions from this section are not related to the age of moraine sedimentation and most likely indicate the period of the Chagan river incision into the ancient glacial deposits.

In the case of insects, most published DNA barcoding studies focus on species of the Ephemeroptera, Trichoptera, Hymenoptera and especially Lepidoptera. In this study we test the efficiency of DNA barcoding for true bugs (Hemiptera: Heteroptera), an ecological and economical highly important as well as morphologically diverse insect taxon. As part of our study we analyzed DNA barcodes for 1742 specimens of 457 species, comprising 39 families of the Heteroptera. We found low nucleotide distances with a minimum pairwise K2P distance ,2.2% within 21 species pairs (39 species). For ten of these species pairs (18 species), minimum pairwise distances were zero. In contrast to this, deep intraspecific sequence divergences with maximum pairwise distances .2.2% were detected for 16 traditionally recognized and valid species. With a successful identification rate of 91.5% (418 species) our study emphasizes the use of DNA barcodes for the identification of true bugs and represents an important step in building-up a comprehensive barcode library for true bugs in Germany and Central Europe as well.
