Ectoparasites Of Bats In Mongolia (Ischnopsyllidae, Nycteribiidae, Cimicidae And Spinturnicidae), Ingo Sceffler, Dietrich Dolch, Jargalsaikhan Ariunbold, Nyamsuren Batsajchan, Andreas Abraham, Klaus Thiele Jan 2010

Ectoparasites Of Bats In Mongolia (Ischnopsyllidae, Nycteribiidae, Cimicidae And Spinturnicidae), Ingo Sceffler, Dietrich Dolch, Jargalsaikhan Ariunbold, Nyamsuren Batsajchan, Andreas Abraham, Klaus Thiele

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

For large parts of the world, the knowledge of bat ectoparasites is still scanty. Regarding Mongolia, only few studies exist to date. This paper analyzes results from extensive captures between 2005-2008, carried out in different sites of Mongolia. Discussed ectoparasites include bat fleas, (Ischnopsyllidae), bat flies (Nycteribiidae), and bat bugs (Cimicidae) and spinturnicid mites (Spinturnicidae). A number of species found in this study were new records for Mongolia, and for many species additional sites were reported. For some bat species, the spectrum and frequency of larger ectoparasites could be determined for the first time.

The Institute For Raptor Studies Expeditions In Mongolia, 1994-2000, David H. Ellis

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

In 1994, 1995, 1997, 1998, and 2000, I led small teams of biologists across Mongolia in search of Saker falcon (Falco cherrug Gray) and golden eagle (Aquila chrysaetos) eyries. We also counted raptors along our march route during the first three years. These expeditions documented: (1) occupancy and productivity rates, and described eyrie sites, for Saker falcons (150 territories, 182 eyries) and golden eagles (27 known breeding territories), (2) mortality of Sakers and ipland buzzards (Buteo hemilasius) due to entanglement with trash in nests and loss of golden eagle eggs due to concealment by trash in nests, …

The Geography Of Buddhist Pilgrimage In Asia, Robert Stoddard Jan 2010

The Geography Of Buddhist Pilgrimage In Asia, Robert Stoddard

Geography Program: Faculty Publications

A pilgrimage is a journey to a sacred place motivated by religious devotion. Although the term may be applied to a meditative search for new spiritual experiences, prolonged wanderings, or travel to a place of nostalgic meaning for an individual, here the word refers to the physical journey to a distant site regarded as holy. As defined in this essay, pilgrimage excludes local and family places of worship; therefore the spatial component of distance is critical.

Throughout the world and in numerous faiths, pilgrimages differ from other forms of worship because of the emphasis on the unique roles of movement …


Great Plains Region From Encyclopedia Of Religion In America, Volume 2, Robert H. Stoddard Jan 2010

Great Plains Region From Encyclopedia Of Religion In America, Volume 2, Robert H. Stoddard

Geography Program: Faculty Publications

To understand the religions of a region, it is helpful to examine its environmental characteristics and the history of human occupation of that land because interpretations and forms of worship often reflect the environment with which believers cope. Although characteristics of the natural environment are intricately incorporated into most ancient religions, this relationship may be less obvious in religions with creeds and set of beliefs enunciated by historic figures. Here focus is on how the religious history of the Great Plains distinguishes it from other parts of America.

Niobrara National Scenic River Condition Assessment, Sunil Narumalani, Gary D. Willson, Christine K. Lockert, Paul B. T. Merani

United States National Park Service: Publications

Executive Summary

Niobrara National Scenic River spans a 122-km (76-mile) long reach of the Niobrara River in rural, north-central Nebraska. The scenic river encompasses 9,338 ha (23,074 acres) of land and water, all of which is in private ownership, except for about 320 ha (790 acres). Because the scenic river does not own land, it achieves management goals by coordinating and collaborating with federal, state, and local jurisdictions and private landowners.

The central Niobrara River Valley is often referred to as a “biological crossroads” with plant and animal species representative of northern boreal forest, eastern deciduous forest, rocky mountain coniferous …

Jacob, Robert J. D. Spurr, Jun Wang, Yohei Shinozuka, Bruce E. Anderson, Antony D. Clarke, Jack Dibb, Cameron Mcnaughton, Rodney Weber

Department of Earth and Atmospheric Sciences: Faculty Publications

We use an ensemble of satellite (MODIS), aircraft, and ground‐based aerosol observations during the ICARTT field campaign over eastern North America in summer 2004 to (1) examine the consistency between different aerosol measurements, (2) evaluate a new retrieval of aerosol optical depths (AODs) and inferred surface aerosol concentrations (PM2.5) from the MODIS satellite instrument, and (3) apply this collective information to improve our understanding of aerosol sources. The GEOS‐Chem global chemical transport model (CTM) provides a transfer platform between the different data sets, allowing us to evaluate the consistency between different aerosol parameters observed at different times and …


Vaishno Devi, The Most Famous Goddess Shrine In The Siwāliks, Georgana Foster, Robert Stoddard Jan 2010

Vaishno Devi, The Most Famous Goddess Shrine In The Siwāliks, Georgana Foster, Robert Stoddard

Geography Program: Faculty Publications

Vaishno Devi in Jammu has been designated as the "Elder Sister" among the six other Devi shrines in a fairly narrow belt of the Siwāliks between the Yumunii and Chenāb Rivers. During the last few decades Vaishno Devi has become especially important. Pilgrimage to the shrine has increased from 30,000 to almost 7 million since Independence, when the political geography of the region increased accessibility, both physically and perceptually. The growth in the number of visitors can be attributed also to a change in administration of the shrine and to the tremendous increase in religious tourism. Vaishno Devi is now …


The Changing Landscape Of A Rural Region: The Effect Of The Harry S Truman Dam And Reservoir In The Osage River Basin Of Missouri, Melvin Arthur Johnson Dec 2009

The Changing Landscape Of A Rural Region: The Effect Of The Harry S Truman Dam And Reservoir In The Osage River Basin Of Missouri, Melvin Arthur Johnson

Department of Geography: Dissertations, Theses, and Student Research

The Harry S Truman Dam and Reservoir project is of immense size. Many thousands of tons of raw materials were required to complete the construction of the dam and relocations. Millions of dollars were spent to acquire land, compensate those who were displaced, and to pay those who were employed in the planning, purchasing, coordinating, defending, and managing the myriad of contractors, contracts, and legal defenses. The affected area of the project is not only complex physically but also socially and economically. It is, therefore, not surprising that the counties studied (Benton, Henry, and St. Clair) would react in different …


Remote Sensing To Detect The Movement Of Wheat Curl Mites Through The Spatial Spread Of Virus Symptoms, And Identification Of Thrips As Predators Of Wheat Curl Mites, Abby R. Stilwell Dec 2009

Remote Sensing To Detect The Movement Of Wheat Curl Mites Through The Spatial Spread Of Virus Symptoms, And Identification Of Thrips As Predators Of Wheat Curl Mites, Abby R. Stilwell

Department of Entomology: Dissertations, Theses, and Student Research

The wheat curl mite (WCM), Aceria tosichella Keifer, transmits three viruses to winter wheat: wheat streak mosaic virus, High Plains virus, and Triticum mosaic virus. This virus complex causes yellowing of the foliage and stunting of plants. WCMs disperse by wind, and an increased understanding of mite movement and subsequent virus spread is necessary in determining the risk of serious virus infections in winter wheat. These risk parameters will help growers make better decisions regarding WCM management. The objectives of this study were to evaluate the capabilities of remote sensing to identify virus infected plants and to establish the potential …


Detection And Measurement Of Water Stress In Vegetation Using Visible Spectrum Reflectance, Arthur Zygielbaum Dec 2009

Detection And Measurement Of Water Stress In Vegetation Using Visible Spectrum Reflectance, Arthur Zygielbaum

Department of Geography: Dissertations, Theses, and Student Research

At any scale, from a single microbe to the planet that nurtures us, water defines our place in the universe. It provides the hydraulic forces needed to give plants structure, and the medium enabling photosynthesis, the basis for most life on Earth, to occur. Knowledge of plant water status is vital to understanding the state or condition of vegetation, information which is essential to disciplines as diverse as agriculture, geography, and climatology. Non-destructive and remote sensing of plant water status allows the gathering of such information across wide geographic extents and over long periods of time. Monitoring vegetation remotely requires …


Long-Term Agricultural Land-Use Trends In Nebraska, 1866–2007, Tim L. Hiller, Larkin A. Powell, Tim D. Mccoy, Jeffrey J. Lusk Oct 2009

Long-Term Agricultural Land-Use Trends In Nebraska, 1866–2007, Tim L. Hiller, Larkin A. Powell, Tim D. Mccoy, Jeffrey J. Lusk

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Although landscape changes from anthropogenic causes occur at much faster rates than those from natural processes (e.g., geological, vegetation succession), human perception of such changes is often subjective, inaccurate, or nonexistent. Given the large-scale land-use changes that have occurred throughout the Great Plains, the potential impacts of land-use changes on ecological systems, and the insight gained from knowledge of land-use trends (e.g., to compare to wildlife population trends), we synthesized information related to land-use trends in Nebraska during 1866–2007. We discussed and interpreted known and potential causes of short- and long-term land-use trends based on agricultural and weather data; farm …


Intersections Of Place, Time, And Entertainment In Rural Nebraska In The Late 19th And Early 20th Centuries, Rebecca A. Buller Aug 2009

Intersections Of Place, Time, And Entertainment In Rural Nebraska In The Late 19th And Early 20th Centuries, Rebecca A. Buller

Department of Geography: Dissertations, Theses, and Student Research

As newcomers developed Nebraska settlements in the late 19th and early 20th centuries, they began to shape the space. This study explores the intersections of place, time, and entertainment in rural Nebraska from the beginning of European American settlement in the late 19th century to the end of the Great Depression. Through such examinations, we can better understand the historical geographies of individual and collective human experience. With such knowledge, we can then recognize how entertainment reflected social life, sense of place, place attachment, and the intricacies and larger scale trends of race, ethnicity, gender, age, class, nationality, and religion. …


Pilgrimage Places And Sacred Geometries, Robert Stoddard Jan 2009

Pilgrimage Places And Sacred Geometries, Robert Stoddard

Geography Program: Faculty Publications

Pilgrimage flows, often involving millions of people, attract the attention of scholars seeking to explain these patterns of movement. A multitude of explanations have been attempted, but none has provided an entirely satisfactory understanding about why certain sites attract worshippers to undertake the sacrifices of pilgrimage. It is recognized that, from the perspective of many religious traditions, Earth space is not homogeneous - that specific places are sacred and different from the surrounding profane land. The reasons certain locations are holy and attract pilgrims from afar have long evoked the geographic question: Why are pilgrimage places distributed as they are? …


Stress, Status, And Sociability: Exploring Residential Satisfaction In The Rural Midwest Following Rapid Immigration, James Potter, Rodrigo Cantarero, Amy E. Boren Jan 2009

Stress, Status, And Sociability: Exploring Residential Satisfaction In The Rural Midwest Following Rapid Immigration, James Potter, Rodrigo Cantarero, Amy E. Boren

Architecture Program: Faculty Scholarly and Creative Activity

This investigation examined predictors of residential satisfaction among newly arrived residents (NAR) and long-term residents (LTR) of a rural community following a rapid influx of immigrants into the community. The physical environment, social/cultural aspects of life, and resources and public services were hypothesized to affect perceptions of residential satisfaction. Both LTR and NAR were pleased with environmental attributes, sociocultural attributes, and public services. An inverse relationship was revealed between stress and residential satisfaction. The primary sources of stress for LTR related to economics and social status issues, whereas the primary sources of stress among NAR involved issues concerning family and …

Patterns And Consequences Of Segregation: An Analysis Of Ethnic Residential Patterns At Two Geographic Scales, Kenneth N. N. French Aug 2008

Patterns And Consequences Of Segregation: An Analysis Of Ethnic Residential Patterns At Two Geographic Scales, Kenneth N. N. French

Department of Geography: Dissertations, Theses, and Student Research

American cities are diverse, with people from various ethnic backgrounds calling the city their home. Instead of having numerous culturally mixed neighborhoods, many residential areas are segregated by ethnicity. Also, social opportunities, such as access to jobs and quality education, are not evenly distributed in urban space. In short, separate living spaces may not mean equal living spaces. What are the impacts of living in White or African American or Hispanic or Asian neighborhoods? Thus, it is worthwhile to investigate the patterns and consequences of ethnic residential segregation. This dissertation employs several cartographic, geographic information system (GIS), and statistical techniques …

Up-Date On The Behaviour And Status Of The Critically Endangered Onager, Equus Hemionus Onager, From Iran, Laurent Tatin, Bijan F. Darreh-Shoori, Christophe Tourenq, David Tatin, Bijan Azmayesh

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

The onager, Equus hemionus onager, an Asiatic wild ass endemic to Iran, is categorized as Critically Endangered on the IUCN Red List. Its biology and conservation requirements are poorly documented. We report some observations made in 1997 and 2000 on the behavior and ecology of the two remaining populations, located in the Touran Protected Area and the Bahram-e-Goor Reserve. Recent population counts by the Department of Environment of Iran (471 in the Protected Area, and 96 in the Reserve) are markedly lower than the count of 600-770 made in the 1970s in the Touran Protected Area. We observed social …


Asiatic Wild Ass In Israel, David A. Blank Jan 2007

Asiatic Wild Ass In Israel, David A. Blank

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

The Syrian wild ass (Equus hemionus hemippus) lived in Israel in historic times until the 1930s, when it disappeared from the entire Middle East region. Khulans from other subspecies (E. h. onager - six individulas and E. h. kulan - five individuals) were brought to Israel from European zoos during 1968-69 (the authors of project considered that onager and kulan were the same subspecies) and these animals bred together in the semi-captivity conditions of the Haibar Yotvata Reserve. Later, during a 12-year period from 1982 through 1993, six groups totalling 38 khulans (17 males and 21 females) …

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

In this paper are presented the accounts of 13 identified bat species from a total of 628 captured specimens from 32 locations in Mongolia during three field expeditions. These species accounts include taxonomical, morphological, and ecological data resulting from observations and further analyses. As a result of this work the distribution of some bat species in Mongolia can be drawn in more detail. For instance, Vespertilio murinus is much wider distributed and abundant than the former records indicate. The Plecotus species were clearly identified by genetic analyses combined with morphological characteristics. Moreover, the second record for Eptesicus serotinus and the …

Surviving A Drought: Population Dynamics Of Ochotona Pallasi Pricei In A Dry Steppe, Gobi Altai, Mongolia, Karin Nadrowski, Georg Miehe Jan 2007

Surviving A Drought: Population Dynamics Of Ochotona Pallasi Pricei In A Dry Steppe, Gobi Altai, Mongolia, Karin Nadrowski, Georg Miehe

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

Two distinct life history traits are described from the genus Ochotona, the group of “burrowing” species exhibiting high but fluctuating population densities and the “non-burrowing” species exhibiting relatively stable low population densities. The life history traits are linked to ecosystem dynamics with climatically variable steppe environments hosting “burrowing” species and relatively stable mountainous and rocky habitats hosting “non-burrowing” species. There are few intermediate species, living in both steppe and rocky environments. This study presents survival rates, reproductive rates and a tentative model of population dynamics for Ochotona pallasi pricei, an intermediate species with respect to habitat preference. We …

Quo Vadis Equus Hemionus Hemionus In Mongolia?, Annegret Stubbe, Michael Stubbe, O. Shagdarsuren, Nyamsuren Batsaikhan, Ravčigijn Samjaa

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

Inspired by studies on biodiversity in the South Gobi we were confronted with the human impact on animal communities and endangered animal species, especially the Asiatic wild ass. So the idea was born to organize an international conference with the aim to actualize the status of Equus hemionus in Central Asia and to find ways for better conservation of this species and its habitats. A short review is given on historical exploration, decreasing area and population number of the Dschiggetai. Today the range of the nominate form of Equus hemionus is located in the Gobi region of southern Mongolia/northern China …


Remarks On The Social System Of The Mongolian Wild Ass (Equus Hemionus Hemionus), Gertrud Neumann-Denzau, Helmut Denzau Jan 2007

Remarks On The Social System Of The Mongolian Wild Ass (Equus Hemionus Hemionus), Gertrud Neumann-Denzau, Helmut Denzau

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

So far the social system of Mongolian wild asses is non-uniformly interpreted. The authors describe their own observations from different parts of Mongolia and review data from available publications. The arguments support a territorial social system, which agrees with the social system of all other wild asses in Asia and Africa.
