Beiträge Zur Ökologie Und Verbreitung Der Steppenwühlmaus Microtus Brandti Radde, 1861 In Der Mongolei = Ecology And Distribution Of The Steppe Vole Microtus Brandti Radde, 1861 In Mongolia, N. Dawaa, Michael Stubbe, Annegret Stubbe

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Microtus brandti is one of the most important pest species of Mongolian rodents. Since the publication of Bannikov (1954) the area of expansion is increased, in the Archangaj-Aimag 200 km westward, in the Central Aimag 70 km to the North and in the north-eastern part of Dornogov’- Aimag about 110 km to the South. In years of gradation the plant cover was exterminated up to 100%. We can distinguish a zone of exposed harmfulness with a damage of 70-100%. In this region 16 great centers of infestation were listed. Between 1925 and 1985 six important calamities were noticed, in intervals …

Der Einsatz Der Luzerne-Blattschneiderbiene, Megachile Rotundata (Hymenoptera: Megachilidae), Zur Bestäubung Von Luzerne In Der Mongolei = Management Of The Alfalfa Leaf-Cutter Bee, Megachile Rotundata (Hymenoptera: Megachilidae), For Alfalfa Pollination In Mongolia, Karsten Seidelmann, Čojrog Batchujag, Manfred Dorn

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

The propagation of the alfalfa leaf-cutter bee, Megachile rotundata was tested from 1988 to 1991 on alfalfa seed growing fields at the Uvs-Nuur Basin in the North-West of Mongolia. We used the loose-cell technology in combination with wooden grooved boards (dimensions of the nesting holes: 8 × 110 mm). The climatic conditions at the investigation area proved to be favorable for the rearing of the bees. The average temperature was above 21 °C during 8.5 h by a mean sunshine duration of 6.4 h and sporadic rainfall. Nevertheless, the night temperatures felled below 10 °C and are responsible for a …

Die Parasitierung Der Luzerne-Blattschneiderbiene, Megachile Rotundata (Hymenoptera: Megachilidae), Durch Physocephala Pusilla (Diptera: Conopidae) In Der Mongolei = Parasitization Of The Alfalfa Leaf-Cutter Bee, Megachile Rotundata (Hymenoptera: Megachilidae), By Physocephala Pusilla (Diptera: Conopidae) In Mongolia, Karsten Seidelmann

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Physocephala pusilla Meigen (Diptera: Conopidae) was found to be a dangerous endoparasitoid of the alfalfa leafcutter bee Megachile rotundata F. (Hymenoptera: Megachilidae) in Mongolia. The conopid fly parasitizes adults and causes their early death. In 1989 and 1990, 16% and 15% respectively of the M. rotundata females were found dead in front of the bee shelter. However, the number of bees (females and males) dying in the field is unknown. These bees cause a contamination of the alfalfa fields due to an increase of the conopid population. Therefore, Ph. pusilla becomes a serious problem for the management of M. rotundata …

Facts From A Year Of Drought: Forage Competition Between Livestock And The Mongolian Pika (Ochotona Pallasi) And Its Effects On Livestock Densities And Body Condition, Vroni Retzer

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Burrowing small mammals in grasslands have long been regarded as pests because they compete for forage with livestock and reduce the forage availability for livestock by destroying pastures through their intensive digging activity.

In order to investigate forage competition between the Mongolian Pika (Ochotona pallasi) and livestock an exclosure experiment consisting of four different treatments was set up. The treatments were: 1) accessible only for pikas, (only pika) 2) accessible only for livestock, (only livestock) 3) accessible for both herbivore groups (pika & livestock) and 4) no grazing (no grazing). During the investigation period all requirements for forage …

Natürliche Und Nutzungsbedingte Land- Und Bodendegradationsprozesse, Untersucht Am Unteren Orchon (Nord-Mongolei) = Naturally And Land Use Caused Land And Soil Degradation Processes, Studied At The Lower Orchon (Northern Mongolia), Christian Opp

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Landscape-ecological investigations were carried-out within the forest steppe of Northern Mongolia. The site conditions of the partly by agriculture used area of Cagaan Tolgoj at the Lower Orchon (Aimag Selenge) were analysed in seven test areas. Results of soil analysis are given. The evaluation of soil cover and partly vegetation cover was carried-out with special regard, to degradation phaenomena. It is based on field analysis, measurements during the soil survey and the detection of soil degradation parameter with the help of laboratory analysis. Among naturally and land use caused factors of soil status and of the changing conditions within forest …

The Occurrence Of Forest Plants In The Desert Mountains Of Mongolia And Their Bearing On The History Of The Climate, Eckehart Johannes Jäger

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

The isolated occurrences of forest plants in the desert mountains of southern Mongolia raise questions as to the mode of their dispersal and the age and direction of former range connections. For species without a possibility of long distance dispersal, a once continuous distribution over the southern Mongolian mountain chains must be assumed. To the Gurvan Saykhan mountains, the forest plants immigrated from the west. Nevertheless their distribution types are eastern Asiatic, or else Eurasiatic with an eastern center of gravity. This shows that the seasonal type of the recent climate with summer rains in eastern Asia influences vegetation composition. …

Die Gasteromyceten Der Mongolei Und Ihre Bedeutung Für Die Systematik, Chorologie Und Ökologie) = The Mongolian Gasteromycetes And Their Importance For The Systematics, Chorology, And Ecology, Heinrich Dörfelt

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

More than fifty species of Gasteromycetes were collected in Mongolia from 1970 to 2002. Five new species in the genera Geastrum, Lycoperdon, Gastrosporium, and Colus were described by Pilát (1972), Kreisel (1975), Dörfelt (1981) and Dörfelt & Bumžaa (1986). The importance of Mongolian Gasteromycetes for few taxonomical, chorological or ecological problems is discussed in this paper, especially for the species Battarraea phalloides, Disciseda arida, D. bovista, D. candida, Gastrosporium asiaticum, Geastrum simplex, G. corollinum (G. recolligens), G. deylii, G. floriforme, G. huneckii, G. hungaricum, G. …

Über Die Federmerkmale Der Mongolischen Sakerfalken Falco Cherrug Milvipes Im Vergleich Zu Den Westlichen Sakerfalken Der Unterart F. Ch. Cherrug Und Bemerkungen Über Die Gefiedermerkmale Des “Altaifalken”, Wolf-Dieter Busching

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

The different plumage characteristics of the Mongolian Saker Falco cherrug milvipes and the nominate race F. ch. cherrug are discussed. It could be shown that both races are polymorphic. According to Baumgart (1997), Sakers don’t need uniform plumages because they live on nearly blind voles. Due to that there seems to be no selection pressure from victims side. The same phenomenon is observable with Buteo buteo and the typical Mongolian Buteo hemilasius.

Whereas young Sakers of the nominate race cherrug equal more or less already adults, are the differences in the plumage of juv. and ad. milvipes great enough. …

Wild Bactrian Camel Conservation, Richard P. Reading, Evan S. Blumer, Henry Mix, Jadamsuren Adiya

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

The wild Bactrian camel (Camelus bactrianus ferus) is critically endangered throughout its range in China and Mongolia. Yet, wild camels remain poorly understood, with knowledge derived primarily from a few short studies and anecdotal information. We initiated a wild camel conservation project to determine the reasons for camel decline and to develop a program to address those problems.

We are employing satellite telemetry to gather data on wild camel movement patterns, home ranges, habitat use, and sources of mortality. We are also collecting feces from camels and wolves to determine important forage plants and to begin to assess …

Flora Of The Gurvan Saykhan Mountains, Tseden Jamsran, Batlai Oyuntsetseg, Radnaakhand Tungalag

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Although two major books have been published on the Mongolian flora regional data are often still lacking due to the vast expanses of the country. Therefore we used published information and data from our own fieldwork to compile a relatively comprehensive inventory of the flora of the Gobi Gurvan Saykhan mountains in southern Mongolia.

Preface to Erforschung biologischer Ressourcen der Mongolei, band 9, 2005.

First paragraph:

The present volume 9 of ”Biologische Ressourcen der Mongolei” continues the cooperation between the National University of Mongolia, Ulaan Baatar, and German academic institutions, mainly led by the University of Halle-Wittenberg. Thus, the volume stands in a tradition stretching now over 40 years (described in the respective chapter written by Stubbe et al.), but also raises new issues and topics. The chapters provided by Ts. Jamsran, W. Hilbig, E. Jäger, M. Stubbe und A. Stubbe demonstrate nicely that this cooperation is not only based on continued institutional …

Winter Pasture Conditions And Forage Use By Argali (Ovis Ammon) In Gobi Gurvan Saykhan National Park, Bayart Mandakh, Ganchimeg J. Wingard, Richard P. Reading

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Conservation of Argali sheep (Ovis ammon) presents a significant challenge to biologists and conservation managers in Mongolia. Argali are endangered and available data suggest that their numbers are declining. However, the mechanisms causing this decline are poorly understood. Recent research suggests that declines in Argali sheep numbers may be due in part to competition with domestic livestock for forage.

Following privatization of herd ownership in 1991, livestock numbers increased dramatically across Mongolia. With this increase, many herders expanded grazing onto more marginal rangeland resulting in increased competition with wild ungulates and displacement of Argali from their former population …

Ecology Of Argali In Ikh Nartiin Chuluu, Dornogobi Aymag, Richard P. Reading, Sukhiin Amgalanbaatar, Ganchimeg J. Wingard, Danny Kenny, Anthony Denicola

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Argali sheep (Ovis ammon) are listed as threatened in both Mongolia and internationally. Yet, little is known about the biology and ecology of this species. Available data suggests that Argali in Mongolia are declining due to direct poaching and competition with domestic livestock. We initiated several research projects to better understand and conserve the species. In this report we discuss Argali ecology using radio telemetry.

We captured and radio-collared 36 Argali using drive-nets, lamb captures, and dating from 2000–2004. Fifteen collared animals have died: 2 due to capture techniques, 8 from predation, 1 from starvation and exposure, 1 …

Zur Populationsökologie Und Raumnutzung Der Steppenwühlmaus Microtus Brandti (Radde, 1861) In Der Fortpflanzungsperiode, Ulrich Zöphel, N. Dawaa

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

During the growing season between 1988 and 1990 the population biology of Brandt’s vole (Microtus brandti) was observed in a population near Ulaanbaatar. Mark-recapture techniques (1,438 markings, 19,606 recaptures in total) and complementary methods were used. The density maximum was observed in July with 98 (1988); 169 (1989) and 94 (1990) individuals/ha and the population fluctuated by a factor of 7.4.

At the beginning of reproductive period the males disperse over a minimum distance of one female home range whereas the females do not migrate after winter. The typical mating system is promiscuity. Youngsters have been recorded from …

Biodiversity And Ecology Of Soil Oribatid Mites (Acari: Oribatida) In The Grassland Habitats Of Eastern Mongolia, Badamdorj Bayartogtokh

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Composition, abundance, distribution, and diversity of oribatid mite communities were investigated at five study areas in Eastern Mongolia. A total of 88 species of oribatid mites were recorded from the studied areas. The largest number of species (51 spp.) was found in the habitats of river valleys, while the plain steppe which covers the largest area contained the lowest species richness (24 spp.). Three other sub-regions with similar landscape types show approximately the same species richness (39 to 45 spp.), although they are located relatively far from each other. The oribatid mite faunas of all sub-regions were essentially similar to …

Real-Time Reverse Transcription Pcr For Detection And Quantitative Analysis Of Equine Influenza Virus., Michelle Quinlivan, Eugene Dempsey, Fergus Ryan, Sean Arkins, Ann Cullinnane

Articles

Equine influenza is a cause of epizootic respiratory disease of the equine. The detection of equine influenza virus using real-time Light Cycler reverse transcription (RT)-PCR technology was evaluated over two influenza seasons with the analysis of 171 samples submitted for viral respiratory disease. Increased sensitivity was found in overall viral detection with this system compared to Directigen Flu A and virus isolation, which were 40% and 23%, respectively, that of the RT-PCR. The assay was also evaluated as a viable replacement for the more traditional methods of quantifying equine influenza virus, 50% egg infectious dose and 50% tissue culture infectious …

Terrestrial Behavior Of Ateles Spp., Christina J. Campbell, Filippo Aureli, Colin A. Chapman, Gabriel Ramos-Fernández, Kim Matthews, Sabrina E. Russo, Scott Suarez, Laura Vick

School of Biological Sciences: Faculty Publications

Spider monkeys (Ateles spp.) are well known for their highly arboreal lifestyle, spending much of their time in the highest levels of the canopy and rarely venturing to the ground. To investigate terrestriality by Ateles and to illuminate the conditions under which spider monkeys venture to the ground, we analyzed ad libitum data from 5 study sites, covering 2 species and 5 subspecies. Three of the sites are in Central/North America: Barro Colorado Island (BCI), Panama (Ateles geoffroyi panamensis), Santa Rosa National Park, Costa Rica (A. g. frontatus), and Punta Laguna, Mexico (A. g. yucatanensis). The 2 remaining sites are …

Origin And Evolution Of Large Brains In Toothed Whales, Lori Marino, Daniel W. Mcshea, Mark D. Uhen

Veterinary Science and Medicine Collection

Toothed whales (order Cetacea: suborder Odontoceti) are highly encephalized, possessing brains that are significantly larger than expected for their body sizes. In particular, the odontocete superfamily Delphinoidea (dolphins, porpoises, belugas, and narwhals) comprises numerous species with encephalization levels second only to modern humans and greater than all other mammals. Odontocetes have also demonstrated behavioral faculties previously only ascribed to humans and, to some extent, other great apes. How did the large brains of odontocetes evolve? To begin to investigate this question, we quantified and averaged estimates of brain and body size for 36 fossil cetacean species using computed tomography and …

Size Matters: A Test Of Boldness In Eight Populations Of The Poeciliid Brachyraphis Episcopi, Culum Brown, Victoria Braithwaite

Sentience Collection

Individual variation in behaviour within populations may be explained in part by demographics and long-term, stable individual psychological differences. We examined the relation between boldness (taken as the time to emerge from a shelter and explore a novel environment) and body size in eight populations of the poeciliid Brachyraphis episcopi originating from sites upstream and downstream of waterfalls in four rivers that run into the Panama Canal. The relation between body size and time to emerge from a shelter was positive, with larger fish taking longer to emerge. This relation differed between downstream and upstream sites, being significant in the …

Evolution Of Nociception In Vertebrates: Comparative Analysis Of Lower Vertebrates, Lynne U. Sneddon

Veterinary Science and Medicine Collection

Nociception is an important sensory system of major fundamental and clinical relevance. The nociceptive system of higher vertebrates is well studied with a wealth of information about nociceptor properties, involvement of the central nervous system and the in vivo responses to a noxious experience are already characterised. However, relatively little is known about nociception in lower vertebrates and this review brings together a variety of studies to understand how this information can inform the evolution of nociception in vertebrates. It has been demonstrated that teleost fish possess nociceptors innervated by the trigeminal nerve and that these are physiologically similar to …

Aspects Of The Ecology Of A Distinct Population Of Xenosaurus Platyceps From Querétaro, México, Julio A. Lemos-Espinal, Geoffrey R. Smith, Royce E. Ballinger

Papers in Herpetology

Lizards in the genus Xenosaurus (Xenosauridae) show a flattened morphology, which is presumably an adaptation for their crevice-dwelling habits. Despite their general morphological similarities (Ballinger et al., 2000a), there is considerable variation among species and populations in ecological traits, and even populations of nominally the same species (e.g., X. grandis grandis and X. g. agrenon; Ballinger et al., 1995; Lemos-Espinal et al., 2003a) show variation, sometimes as much as between different species.

Populations of Xenosaurus are often geographically isolated (e.g., Pérez Ramos et al., 2000; Nieto Montes de Oca, 2001), and movement appears to be minimal (Lemos-Espinal et al., …

Reflections On Animal Selves, Marc Bekoff, Paul W. Sherman

Sentience Collection

Is self-cognizance a uniquely human attribute, or do other animals also have a sense of self? Although there is considerable interest in this question, answers remain elusive. Progress has been stymied by misunderstandings in terminology, a focus on a narrow range of species, and controversies over key concepts, experimental paradigms and interpretations of data. Here, we propose a new conceptual and terminological framework, emphasizing that degrees of self-cognizance differ among animals because of the cognitive demands that their species-specific social structures and life-history characteristics have placed upon them over evolutionary time. We suggest that the self-cognizance of an organism falls …

Differences In Response To Hypoxia In The Three-Spined Stickleback From Lotic And Lentic Localities: Dominance And An Anaerobic Metabolite, L. U. Sneddon, J. Yerbury

Aquaculture Collection

Dominance hierarchies of the three-spined stickleback Gasterosteus aculeatus from river and pond populations were subjected to hypoxia (20%, range±1%). Under hypoxia, the hierarchies were less stable in terms of rank position and tissue L-lactate was higher in river fish than pond fish under normoxia and hypoxia. Dominant fish gained mass under normoxia but lost mass under hypoxic conditions possibly due to them maintaining high levels of aggression.

The Prevalence Of The Q-Fever Agent Coxiella Burnetii In Ticks Collected From An Animal Shelter In Southeast Georgia, John H. Smoyer Iii

College of Graduate Studies: Theses & Dissertations

Author's abstract: Q-fever is a zoonosis caused by a worldwide-distributed bacterium Coxiella burnetii. Ticks are vectors of the Q-fever agent but play a secondary role in transmission because the agent is also transmitted via aerosols. Most Q-fever studies have focused on farm animals but not ticks collected from dogs in animal shelters. In order to detect the Q-fever agent in these ticks, a nested PCR technique targeting the 16S rDNA of Coxiella burnetii was used. A collection of 450 ticks from the animal shelter were screened via nested PCR and 144 (32%) were positives. The positive PCR products were also …

Seasonal Activity And Reproduction In Bats Of East-Central Nebraska, Kenneth N. Geluso, Russell A. Benedict, Francis L. Kock

Biology Faculty Publications

Information on seasonal activity and reproduction is presented for seven species of bats inhabiting east-central Nebraska (Eptesicus fuscus, Myotis septentrionalis, Nycticeius humeralis, Lasionycteris noctivagans, Lasiurus borealis, L. cinereus, and Pipistrellus subflavus). Early and late dates of capture show five species active in the state for longer periods than previously reported. During some years, E. fuscus and M. septentrionalis emerge from winter torpor in March and feed on insects. Some E. fuscus inhabiting a floodplain forest in summer use houses in nearby towns as hibernacula, and year-round use of buildings by E. fuscus is substantial compared to other species of bats. …
