Review Of Conspecific Attraction And Area Sensitivity Of Grassland Birds, David R.W. Bruinsma, Nicola Koper Oct 2012

Review Of Conspecific Attraction And Area Sensitivity Of Grassland Birds, David R.W. Bruinsma, Nicola Koper

Great Plains Research: A Journal of Natural and Social Sciences

Many species of grassland birds are area sensitive, which may exacerbate the ecological effects of the extensive loss and fragmentation of grasslands that has taken place across the northern Great Plains. However, the reasons for this area sensitivity are unclear, as vegetation structure, matrix composition, and restriction of movements among patches do not seem to provide viable explanations for species native to grasslands. Con specific attraction, whereby species are behaviorally stimulated to select habitat or establish territories near individuals of the same species, may help explain this area sensitivity. We review and discuss theoretical and empirical research on avian conspecific …


Review Of Birds Of Southwestern Nebraska: An Annotated Check-List Of Species In The North And South Platte River Valleys And At Lake Mcconaughy. By Mary Bomberger Brown, Stephen J. Dinsmore, And Charles R. Brown., Wayne Mollhoff Oct 2012

Review Of Birds Of Southwestern Nebraska: An Annotated Check-List Of Species In The North And South Platte River Valleys And At Lake Mcconaughy. By Mary Bomberger Brown, Stephen J. Dinsmore, And Charles R. Brown., Wayne Mollhoff

Great Plains Research: A Journal of Natural and Social Sciences

Opening with a map of the region under study, Birds of Southwestern Nebraska proceeds, in its introduction, to a summary of the presettlement landscape and a description of the large-scale habitat changes occurring since then, along with avian responses to those changes. While crediting previous avian studies in southwestern Nebraska, often not readily available to the public, the authors note this area initially received little attention from ornithologists, who tended to focus on other biologically unique parts of the state, such as the Sandhills, forests, and Pine Ridge. The body of the book consists of a list of species reported …


Channel Width And Least Tern And Piping Plover Nesting Incidence On The Lower Platte River, Nebraska, Joel G. Jorgensen, Mary Bomberger Brown, Andrew J. Tyre Apr 2012

Channel Width And Least Tern And Piping Plover Nesting Incidence On The Lower Platte River, Nebraska, Joel G. Jorgensen, Mary Bomberger Brown, Andrew J. Tyre

Great Plains Research: A Journal of Natural and Social Sciences

Endangered interior least terns (Sternula antillarum athalassos) and threatened northern Great Plains piping plovers (Charadrius melodus) nest together on midstream sandbars in large rivers in the interior of North America. We investigated the relationship between river channel width and tern and plover nesting incidence on the lower Platte River, Nebraska, using a model-based logistic regression analysis. Multiple channel width measurements and a long-term nesting data set were used in the analysis. Nesting incidence was positively associated with increasing river channel width proximal to the nesting site. At a greater distance, up to 802 m away from …


Wetland Hydrodynamics And Long-Term Use Of Spring Migration Areas By Lesser Scaup In Eastern South Dakota, Sharon N. Kahara, Steven R. Chipps Apr 2012

Wetland Hydrodynamics And Long-Term Use Of Spring Migration Areas By Lesser Scaup In Eastern South Dakota, Sharon N. Kahara, Steven R. Chipps

Great Plains Research: A Journal of Natural and Social Sciences

Lesser scaup (Aythya affinis [Eyton]) populations remain below their long-term average despite improved habitat conditions along spring migration routes and at breeding grounds. Scaup are typically associated with large, semipermanent wetlands and exhibit regional preferences along migration routes. Identifying consistently used habitats for conservation and restoration is complicated by irregular wetland availability due to the dynamic climate. We modeled long-term wetland use by lesser scaup in eastern South Dakota based on surveys conducted during below-average (1987-1989) and above-average (1993-2002) water condition years. Wetland permanence, longitude, and physiographic region were all significant determinants of use (P < 0.01). Long-term use was best described by a quadratic equation including wetland surface area variability, an index of wetland hydrodynamics that is linked to productivity, biodiversity, and value to waterfowl. Contrary to previous findings, our study shows that over the long term, lesser scaup are more than twice as likely to use permanent wetlands as they are semipermanent wetlands. The northern region of South Dakota's Prairie Coteau, which holds the highest density of hydrologically dynamic permanent wetlands, should be considered an area of conservation concern for lesser scaup. The criteria we identified may be used to identify important lesser scaup habitats in other regions of the Prairie Pothole Region.


A Conceptual Model To Facilitate Amphibian Conservation In The Northern Great Plains, David M. Mushet, Ned H. Euliss Jr., Craig A. Stockwell Apr 2012

A Conceptual Model To Facilitate Amphibian Conservation In The Northern Great Plains, David M. Mushet, Ned H. Euliss Jr., Craig A. Stockwell

Great Plains Research: A Journal of Natural and Social Sciences

As pressures on agricultural landscapes to meet worldwide resource needs increase, amphibian populations face numerous threats including habitat destruction, chemical contaminants, disease outbreaks, wetland sedimentation, and synergistic effects of these perturbations. To facilitate conservation planning, we developed a conceptual model depicting elements critical for amphibian conservation in the northern Great Plains. First, we linked upland, wetland, and landscape features to specific ecological attributes. Ecological attributes included adult survival; reproduction and survival to metamorphosis; and successful dispersal and recolonization. Second, we linked ecosystem drivers, ecosystem stressors, and ecological effects of the region to each ecological attribute. Lastly, we summarized information on …


Reproduction And Population Characteristics Of White-Tailed Jackrabbits In South Dakota, Charles Dieter, Dustin Schaible Apr 2012

Reproduction And Population Characteristics Of White-Tailed Jackrabbits In South Dakota, Charles Dieter, Dustin Schaible

Great Plains Research: A Journal of Natural and Social Sciences

We evaluated the reproductive biology of314 white-tailed jackrabbits (Lepus townsendii) in 44 counties throughout South Dakota from June 2004 to September 2005. We classified jackrabbits as juveniles or adults based on the closure of the proximal epiphysis of the humerus using X-ray analysis. We determined annual reproductive activity through fluctuations in measured weights of reproductive organs for both sexes. The 2005 breeding season started in late February and proceeded until mid-July, approximately 142 days, allowing for females to potentially produce 3.3 litters. We found four distinct breeding periods by the overlap of estimated conception and parturition dates. Mean …


Nonlinear Effects Of Group Size On The Success Of Wolves Hunting Elk, Daniel R. Macnulty, Douglas W. Smith, L. David Mech, John A. Vucetich, Craig Packer Jan 2012

Nonlinear Effects Of Group Size On The Success Of Wolves Hunting Elk, Daniel R. Macnulty, Douglas W. Smith, L. David Mech, John A. Vucetich, Craig Packer

USGS Northern Prairie Wildlife Research Center

Despite the popular view that social predators live in groups because group hunting facilitates prey capture, the apparent tendency for hunting success to peak at small group sizes suggests that the formation of large groups is unrelated to prey capture. Few empirical studies, however, have tested for nonlinear relationships between hunting success and group size, and none have demonstrated why success trails off after peaking. Here, we use a unique dataset of observations of individually known wolves (Canis lupus) hunting elk (Cervus elaphus) in Yellowstone National Park to show that the relationship between success and group …

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

A collection of recent skeletal remains from the Asiatic wild ass (Equus hemionus hemionus PALLAS) was prepared and stored in the Museum of Domesticated Animals “JULIUS KÜHN” in Halle, Germany.

The collection is based on carcass remains sampled between 2001 and 2006 under the leadership of Michael Stubbe during joint Mongolian-German Biological Expeditions

Skeletal remains of 43 individual specimens were studied (18 mares, 15 stallions, and 10 juvenile asses). The determination of sex and age was initially based on carcass information from observations made in situ in the field. Subsequently, skull traits, including dentition and development of canine teeth …


Biodiversity And Evolutionary Development Of Oligocene-Pliocene Lagomorphs (Lagomorpha, Mammalia) Of Mongolia, M. A. Erbajeva Jan 2012

Biodiversity And Evolutionary Development Of Oligocene-Pliocene Lagomorphs (Lagomorpha, Mammalia) Of Mongolia, M. A. Erbajeva

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

Lagomorphs (pikas and hares) are an ancient group of small mammals originated in Asia in the Paleocene-Eocene. The earliest evidence of their presence in Mongolia is dated to the Early Oligocene. The taxa flourished during the Late Oligocene, Miocene and Pliocene; at the Late Pliocene they were reduced both in their diversity and in abundance. No data on lagomorph are known from the Pleistocene and Holocene, though there are 7 taxa of lagomorphs present in the modern fauna. Altogether, more than 50 lagomorph species, extinct at present, are known to have existed in Mongolia since the Oligocene through the Late …


50 Years Mongolian-German Biological Expeditions And Their Future = Fifty Years Mongolian-German Biological Expeditions And Their Future, Michael Stubbe, Ravčigijn Samjaa, Annegret Stubbe Jan 2012

50 Years Mongolian-German Biological Expeditions And Their Future = Fifty Years Mongolian-German Biological Expeditions And Their Future, Michael Stubbe, Ravčigijn Samjaa, Annegret Stubbe

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

First two paragraphs:

In 2012 we celebrate the 50th anniversary of the Mongolian-German Biological Expeditions. The roots can be found in the old German-Russian scientific relationships in the history of the University Halle-Wittenberg in connection with August Hermann Francke (1663–1727) and his Foundations (founded in 1698). It’s a long tradition, dating back to the 18th century when early researchers as Georg Wilhelm Steller (1709 –1746) or Peter Simon Pallas (1741–1811) reached the northern border of Mongolia. Other sources of close connections between Halle and Russia are given by persons as the physician Friedrich Hoffmann (1660–1742), the mathematician Christian Wolff (1679-1754) …

Home Range Characteristics Of Corsac And Red Foxes In Mongolia, Tserendorjiin Munkhzul, J. D. Murdoch, R. P. Reading

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

Red (Vulpes vulpes) and corsac foxes (V. corsac) live sympatrically throughout most of Mongolia, but few details of their home range characteristics exist. We captured and radio-tagged 13 red fox (♂ = 5, ♀ = 8) and 15 corsac foxes (♂ = 8, ♀ = 7) between 2004 and 2008. We tracked their movements to estimate home range sizes and examined the effects of four factors on home range size, including sex, age, season, and year. We determined mean home range size for 12 red and 10 corsac foxes that had sufficient data using fixed kernel …

Long-Term Research On Biodiversity In West Khentey, Northern Mongolia, Michael Mühlenberg

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

Biodiversity is studied at ecosystem, community, and species level around Khonin Nuga, where the University Goettingen supports a research station since 15 years (established 1997 in cooperation with the National University of Mongolia). In that period 39 scientists have been involved and 67 students graduated with theses (7 PhD) about field work at that station. Inventories started at 1998 for several taxa and are now compiled in a book, which will be printed 2012 in Ulaanbaatar. It covers fungi, lichens, plants, several insect groups, spiders, crustaceans, and all vertebrate classes. For all taxa adequate experts proved the species lists. Because …


First Stable Isotope Analysis Of Asiatic Wild Ass Tail Hair From The Mongolian Gobi, Micha Horacek, Petra Kaczensky, Merina Burnik Sturm Jan 2012

First Stable Isotope Analysis Of Asiatic Wild Ass Tail Hair From The Mongolian Gobi, Micha Horacek, Petra Kaczensky, Merina Burnik Sturm

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

Stable isotope analysis has become a powerful tool to study feeding ecology, water use or movement pattern in contemporary, historic and ancient species. Certain hair and teeth grow continuously, and when sampled longitudinally can provide temporally explicit information on dietary regime and movement pattern. In an initial trial, we analysed a tail sample of an Asiatic wild ass (Equus hemionus) from the Mongolian Gobi. We found seasonal variations in H, C, and N isotope patterns, likely being the result of temporal variations in available feeds, water supply and possibly physiological status. Thus stable isotope analysis shows promise to …

Long-Term Ecology Of Asiatic Wild Ass (Equus H. Hemionus Pallas) In Central Asia, Annegret Stubbe, Michael Stubbe, Nyamsuren Batsaikhan, Ravčigijn Samjaa

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

The main population of the nominate form Equus hemionus hemionus Pallas, 1775 occurs in the south-east Gobi desert of Mongolia. From 2003 to 2012 we studied the reproductive ecology and mortality of dschiggetajs or khulans (English also ‘hulan’). During these years, the rate of reproduction was variable, ranging from 6.4% to 23.0% depending on climate, feeding conditions, and fitness of the mares. Our research shows that there appears to be a relationship between minimum temperatures in June (main foaling time) and rate of successful reproduction. The primary cause of decline in the numerical density of the population of E. hemionus …

Herpetological Diversity Of Mongolia And Its Conservation Issues, Khorloo Munkhbayar, M, Munkhbaatar Jan 2012

Herpetological Diversity Of Mongolia And Its Conservation Issues, Khorloo Munkhbayar, M, Munkhbaatar

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

From the viewpoint of evolution, the classes of amphibians and reptiles could be considered as relicts, and because they are poikilothermic animals, it’s very difficult for these species to live under the dry and cold climatic conditions in Mongolia. Even species diversity is poor, Mongolian herpetological composition is unique, highly adopted to the country’s harsh climate and originated a long time ago.

In Mongolia, six species of amphibians belong to four genera, four families and two orders and the recorded 21 species of reptiles belong to 13 genera in six families of two suborders.

Ecology And Behaviour Of The Black-Billed Capercaillie (Tetrao Urogalloides Stegmanni) In The Khentej Mountains, Mongolia, Siegfried Klaus, Karl-Heniz Schindlatz, Alexander V. Andreev, Hans-Heiner Bergmann

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

Introduction

A common inhabitant of East Siberian larch forests, the Siberian or black-billed capercaillie (Tetrao urogalloides) ranges south to the limits of the boreal forests in the northern Mongolian mountains and east to the very coast of the Asian continent (KLAUS et al. 1989). Tetrao urogalloides MIDDENDORF (1851) has priority over T. parvirostris BONAPARTE (1856). Therefore, we prefer the T. urogalloides.

The subspecies T.u. stegmanni was first described on the basis of morphological differences by POTAPOV (1985) using specimens collected during Russian expeditions by KOZLOVA (1930). This description was based on 18 males in the collection at …

The studies in recent years (2000-2011) have allowed to make more precise the list and ranges of Mongolian fish. This is connected with new findings as well as the continuing process of invasion of alien species. Climate change and increase of human impact transformed ranges and local distribution of fish during last 30 years. Bias on ratio of ecological guilds, number of pathological findings are increasing, and declining of local diversity, rate of growth and fecundity of many species of fish are observed. In the course of long-term observation was confirmed periodically drying of waters of the Central Asian Lake …

“Agrionemys Kazachstanica Terbishi” Or The Two-Faced Mongolian Steppe Tortoise, Hermann Ansorge, Uwe Fritz, Khayankhyarvaa Terbish, Setev Shar

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

Although no extant native turtle and tortoise species is known to occur in Mongolia, a new subspecies of the Central Asian tortoise was described by Chkhikvadze under the name Agrionemys kazachstanica terbishi in 2009. The description was based on a mummified tortoise kept in a museum collection. Since then the Mongolian steppe tortoise has been considered as an endemic taxon Testudo horsfieldii terbishi (Chkhikvadze, 2009) for Mongolia.

However, there is no evidence for the occurrence of any wild tortoise species in Mongolia, even in the putative area of origin of the type specimen. The closest confirmed occurrence of Central Asian …

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

One of the most conspicuous detrito- and phytodetritophagous groups of beetles in the Asian steppes and deserts is the family Tenebrionidae (Coleoptera, Polyphaga) (KONSTANTINOV et al. 2009). Mongolia harbors a rich diversity of these beetles with 215 species and 50 genera of Tenebrionidae listed for the country (MEDVEDEV 1990), many of them restricted to its arid parts, where they obtain high abundances and dominate – together with ants – the insect soil fauna (PFEIFFER et al. 2003). Their dark color may be a means to withstand the high radiation at daytime; however, a large number of species is night active …

Magnitude And Structure Of Lymantria Dispar Asiatica Infestations Of Common Forest Steppe Tree Species In Northern Mongolia, Nina Tiralla, Kai Füldner, Stefan Schütz

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

Lymantria dispar L. is one of the most serious forest pests worldwide by infesting large forest areas involving massive tree dieback. Unlike outbreaks of Lymantria dispar L. in Germany that cause massive defoliation, observations of outbreaks of Lymantria dispar asiatica made in the research area Khonin Nuga, West Khentii, Mongolia during the past six years showed only punctual defoliation, and dieback was extremely scarce. However, information on the performance of Lymantria dispar asiatica and the corresponding reaction of host tree species in Khonin Nuga is rare. Therefore, this study concentrates on the examination of primarily affected tree species and the …
