Boreas, Vol. 44, pp. 638–657. 10.1111/bor.12133. ISSN 0300-9483. Knowledge of present-day communities and ecosystems resembling those reconstructed from the fossil record can help improve our understanding of historical distribution patterns and species composition of past communities. Here, we use a unique data set of 570 plots explored for vascular plant and 315 for land-snail assemblages located along a 650-km-long transect running across a steep climatic gradient in the Russian Altai Mountains and their foothills in southern Siberia. We analysed climatic and habitat requirements of modern populations for eight land-snail and 16 vascular plant species that are considered characteristic of the full-glacial environment of central Europe based on (i) fossil evidence from loess deposits (snails) or (ii) refugial patterns of their modern distribu- tions (plants). The analysis yielded consistent predictions of the full-glacial central European climate derived from both snail and plant populations. We found that the distribution of these 24 species was limited to the areas with mean annual temperature varying from À6.7 to 3.4 °C (median À2.5 °C) and with total annual precipitation vary- ing from 137 to 593 mm (median 283 mm).

  • Pupilla Loessica LOŽEK 1954 (Gatropoda: Pulmonata: Pupillidae)
    Eiszeitalter und Gegenwart 58/1 55–69 Hannover 2009 Quaternary Science Journal Pupilla loessica LOŽEK 1954 (Gastropoda: Pulmonata: Pupillidae) – “A Living Fossil” in Central Asia? STEFAN MENG & MATTHIAS H. HOFFMANN *) Abstract: LOŽEK (1986) is of the opinion that Pupilla loessica has been found recently in Central Asia. The aim of this study is to provide some initial, concrete contributions to the discussion of this subject. It should be understood as a basis for further investigations. During recent visits on site between 1995 and 2006 in Central Asia in the Russian Altay, in Northern Mongolia, in the Baikal region and in the Tien Shan, numerous recent malacocenoses were examined. In many places evidence was found of a form of Pupilla which had not previously been described from this region; its shell morphology cannot be distinguished from Pupilla loessica. Its distribution is concentrated in the strongly continental Khrebet Saylyugem in the South Eastern Altay. The probability of the occurrence of Pupilla loessica in Central Asia is supported, apart from the shell morphology criteria, by the preference of this species for more continental types of habitat with average annual temperatures markedly below 0° C and the corresponding accompanying fauna adapted to the cold, including e.g. Columella columella, Vertigo genesii, Vallonia tenuilabris, etc., which make these fauna easily comparable to the Pleistocene glacial associations of the Central European region. [Pupilla loessica LOŽEK 1954 (Gastropoda: Pulmonata: Pupillidae) –“Ein lebendes Fossil” in Zentrala- sien?] Kurzfassung: LOŽEK (1986) vertritt die Ansicht, dass Pupilla loessica rezent in Zentralasien vorkommt.

  • Abstract Form
    FOREWORD Vojen Ložek , a prominent Czech naturalist, malacologist and a leading personality of the European Quaternary research throughout the second half of the 20th Century celebrates his 80 birthdays at late July 2005. Since time of his first steps in science (his first publication appeared in 1939) amount of knowledge and diversity of topics in natural sciences increased quite a much. The major source of the current boom is a transdisciplinarity – smoothing the boundaries between various distant branches with interconnections between their conceptual and methodological specificities. Nevertheless, until quite a nearest past, such approach has neither been applied nor especially appreciated - simply because it appeared rather impossible that anyone could succeed to performe it without falling in a trap of „jack of all trades but master of none“. In any case, Vojen´s pathaway in science has since its beginning been marked just with such a risky approach. Against expectancy, Vojen demonstrated that it is possible to be a respected master not only in taxonomy of mollusc or in biodiversity and ecology of that group, but at the same time also in phytogeography and geobotanics, in regional geography, sedimentary geology, pedology, archeology or history of science. At the same time, he show how imporant is to integrate all such approaches continuously into vivid programmes of Nature Conservancy, both on local and interregional scales, and in various education projects without any damage to his remarkable international scientific reputation. Already in sixties Ložek grew in a top European expert in the Quaternary research. His achievements in study of faciality of lithogenetic processes and faunal development, and, in particuar, in study of the Holocene environmental dynamics markedly predated the current status of the Quaternary science as an essentially integrative discipline.

Boreas,Vol.48,pp.36–56. https://doi.org/10. 1111/bor.12338. ISSN 0300-9483. Steppe-tundra is considered to have been a dominant ecosystem across northern Eurasia during the Last Glacial Maximum. As the fossil record is insufficient for understanding the ecology of this vanished ecosystem, modern analogues have been sought, especially in Beringia. However, Beringian ecosystems are probably not the best analogues for more southern variants of the full-glacial steppe-tundra because they lack many plant and animal species of temperate steppes found in the full-glacial fossil record from various areas of Europe and Siberia. We present new data on flora, land snails and mammals and characterize the ecology of a close modern analogue of the full-glacial steppe-tundra ecosystem in the southeastern Russian Altai Mountains, southern Siberia. The Altaian steppe-tundra is a landscape mosaic of different habitat types including steppe, mesic and wet grasslands, shrubby tundra, riparian scrub, and patches of open woodland at moister sites.

Alexandrowicz E-mail: [email protected] ABS TRACT The Cave above the Słupska Gate (southern Poland) contains about 2m depth of mollusc-bearing deposits. Radiocarbon and archaeological dating indicate that these deposits accumulated during the Holocene (Preboreal to Subatlantic), although the earliest layers may date from the end of the Pleistocene. Eight layers of silts, sands and loess-like deposits were distinguished at the site. Seven of them contained identifiable snail shells, sometimes in large numbers, and sparse remains of vertebrates and archaeological artefacts. The molluscan assemblages retrieved from the cave contain over 40 taxa and 1,200 specimens. The balance of species distributed among 11 zoogeographical groups enabled us to identify four assemblages which differ in their ecological structure and in the composition of the fauna. The oldest fauna (Late Glacial/Preboreal and/or Preboreal) with many shade-loving species is typical of a cool climate.

  • Climate History and Early Peopling of Siberia
    22 Climate History and Early Peopling of Siberia Jiří Chlachula Laboratory for Palaeoecology, Tomas Bata University in Zlín, Czech Republic 1. Introduction Siberia is an extensive territory of 13.1 mil km2 encompassing the northern part of Asia east of the Ural Mountains to the Pacific coast. The geographic diversity with vegetation zonality including the southern steppes and semi-deserts, vast boreal taiga forests and the northern Arctic tundra illustrates the variety of the present as well as past environments, with the most extreme seasonal temperature deviations in the World ranging from +45ºC to -80ºC. The major physiographical units – the continental basins of the Western Siberian Lowland, the Lena and Kolyma Basin; the southern depressions (the Kuznetsk, Minusinsk, Irkutsk and Transbaikal Basin); the Central Siberian Plateau; the mountain ranges in the South (Altai, Sayan, Baikal and Yablonovyy Range) and in the NE (Stavonoy, Verkhoyanskyy, Suntar-Hajata, Cherskego, Kolymskyy Range) constitute the relief of Siberia. The World- major rivers (the Ob, Yenisei, Lena, Kolyma River) drain the territory into the Arctic Ocean. Siberia has major significance for understanding the evolutionary processes of past climates and climate change in the boreal and (circum-)polar regions of the Northern Hemisphere. Particularly the central continental areas in the transitional sub-Arctic zone between the northern Siberian lowlands south of the Arctic Ocean and the southern Siberian mountain system north of the Gobi Desert characterized by a strongly continental climate regime have have been in the focus of most intensive multidisciplinary Quaternary (palaeoclimate, environmental and geoarchaeological) investigations during the last decades. Siberia is also the principal area for trans-continental correlations of climate proxy records across Eurasia following the East-West and South-North geographic transects (Fig.

  • Snails of Orchards and Farms in West Azerbaijan Province, Iran
    Iranian Journal of Animal Biosystematics (IJAB) Vol.10, No.2, 195-203, 2014 ISSN: 1735-434X Snails of orchards and farms in West Azerbaijan Province, Iran Ahmadi, E. Agricultural Zoology Research Department, Iranian Research Institute of Plant Protection,Tehran, Iran (Received: 17 August 2014 ; Accepted: 3 December 2014 ) During 2012-2013 in a funistic survey of snails, several species of snails were collected and identified; both from orchards, farms and the weeds. In total, 18 species belonging to 17 genera out of 10 families are identified based on morphometric characteristics including (shape and size of operculum, aperture, dextral or sinistral of shell, pneumostome, keel, radula, renal ridge and reproduction system). As a result, Vitrea contortula , Vallonia tenuilabris and Orculella sirianocoriensis identified as new record for Iranian mollusc fauna. Besides, the most damaging species within the yielded list identified as Helicella krynickii that has much importance within the north west of region. Key words: snails, Identification, Fauna, orchards and farms, Weeds, West Azerbaijan province, Iran. INTRODUCTION Snails are significant agricultural pests in humid area worldwide. They feed on seeds, seedlings, leaves, fruits and damage various parts of plants (Wiktor, 1989; Maillard, 1993; Byers and Calvin, 1994; Briner and Frank, 1998; Frank, 1998). Snail damage with increasing cultivated area of orchards and farms has become increasing apparent over the past 30 or 40 years. Data indicated that the damage caused by snails are common in warm wet spring and autumn and snail populations reduced under dry conditions in north west of country (Mirzaei, 1975). The lack of data about identification of snail species in West Azerbaijan province makes it impossible to propose rational means of pest snail damage reduction.
