Investigation Of The Kiang (Equus Kiang, Equidae) Skull From Ladakh, India, Natalia Spasskaya

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

The species-rank of Equus kiang was recently supported by molecular and genetic studies (RYDER & CHEMNICK 1990). Three subspecies are currently recognized in this species: eastern - E. k. holdereri, southern - E. k. polyodon and western - E. k. kiang, differing in some cranial and external features (GROVES & MAZAK 1967). Kiang populations are scarce and widely separated at present; which was a reason for a reassessment of the taxonomic status and distribution of at least one or two of these three races.

An interesting skull of kiang was recovered by N. Paklina and C. van Orden …

Feeding Ecology Of Asiatic Wild Ass Equus Hemionus, Jochen Lengger, Frieda Tataruch, Christian Walzer

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

The Mongolian wild ass or khulan (Equus hemionus) is a potential competitor for forage to reintroduced Przewalski’s horses. To evaluate the major foraging plants of khulan we chose the alkane method that was first described by Mayes in 1984. Different plant species contain varying amounts and proportions of n-alkanes. This fact allows the determination of diet composition by comparing the plant alkane to the fecal alkane pattern. The major advantage is that the method is non-invasive and has been shown to be a reliable method in captive trials. Fecal and plant samples were collected simultaneously and preserved by …

Numbers, Distribution And Social Structure Of Kiang (Equus Kiang Moorcroft 1841) Population In The Southwestern Part Of Tibet, China, Natalia V. Paklina, Chris Van Orden

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

In September - October 1998 we made an extensive survey in southwest Tibet to study numbers, distribution and social structure of the kiang population in this remote part of its range. Kiangs were sighted between 29º 40’ and 32º 50’ N, and 81º- 86º E. They preferred broad flat valleys with lakes at an altitude from 4,000 up to 5,000 m. Small kiang groups and solitary animals were sighted in Transhimalaya. There were no kiangs in Tsangpo (Brahmaputra) River valley, in the sand desert near Ali and in the Clay Mountains near Tsada. Seven old kiang corpses were found along …

Some Information On The Ecology Of Khulan (Equus Hemionus Pallas, 1775) In The Western Part Of The South Gobi Province, Mongolia, D. Tsendjav, S. Purevsuren

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

This short study provides information on the density and distribution of khulans in September 2003 and speculates about factors that negatively influence the khulan population in the sums of Khurmen, Bayandalai, Noyon, Sevrei, and Gurvantes in the South Gobi province.

Turkmenian Kulan (Equus Onager Kulan) Captive Population, Anna Mekarska

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

The Turkmenian kulan (Equus onager kulan) is critically endangered, fewer then 1,500 animals are left in the wild. In 2004, there were additional 570 Turkmenian kulans living in captivity: 156 specimens in Euro-Asian zoos, 83 in Askania Nova Reserve and 331 in Canyon Colorado Equid Sanctuary. Population size in EAZA region is decreasing both in terms of numbers and genetic parameters. Those facts underline the urgent need for coordinating development of Eurasian kulan’s captive population. From 2004 onwards, large efforts to create healthy breeding groups in zoos raised bigger interest in this species in European zoos.

Identification Of Herder-Wild Equid Conflicts In The Great Gobi B Strictly Protected Area In Sw Mongolia, Petra Kaczensky, N. Enkhsaihan, O. Ganbaatar, Christian Walzer

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

In protected areas of Mongolian overgrazing, competition with wild ungulates and poaching are important management concerns. The Great Gobi B Strictly Protected Area (SPA) in SW Mongolia is a re-introduction site for the Przewalski’s horse (Equus ferus przewalskii), a stronghold of the Asiatic wild ass (Equus hemionus), and remains an important grazing area for seminomadic herders. We show the power of simple inventory and monitoring methods to assess herder-wildlife conflicts, by combining data of: (1) human and livestock demographic data, (2) migration patterns, of semi-nomadic herders, (3) monthly surveys of wild- and domestic ungulates, and (4) …

Kiangs (Equus Kiang, Moorcroft 1841) In Sikkim, India, Natalia V. Paklina, Chris Van Orden

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

Between the 5^th and 10^th of March 2001 we completed a 450 km route by car in Northern Sikkim. During the trip along the southern slopes of the Himalayas and Sikkim Plateau we didn’t see a single kiang. According to the local people and military personnel in Sikkim, kiangs are known only in the outer limits of the Sikkim Plateau, where wild animals have a possibility to migrate free over the Chinese-Indian border. In winter only small groups of kiang incidentally come to the Sikkim Plateau from South Tibet. But in May more of them come there and …

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

Since 1975, 25 wildlife surveys have been conducted in the Trans-Altai Gobi. In this paper we summarize results from the last 11 surveys, conducted between October 2000 and April 2005, and discuss our findings together with results from previous surveys.

Assessment Of Non-Metric Skull Characters And Age Determination In The Asiatic Wild Ass Equus Hemionus: A Methodological Approach, Hermann Ansorge, Annegret Stubbe, Nyamsuren Batsaikhan, Ravčigijn Samjaa, Michael Stubbe

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

The report presents the first information on the use of non-metric skull characters and age determination by tooth section for Asiatic wild asses. It was initiated by a collection of more than 400 skulls of the Asiatic wild ass from the Bordzongijn-Gobi 2002-2004. The methodological overview gives a first research prospect in Asiatic Wild Ass concerning the use of non-metric skull characters as a morphological tool for assessing genetic variability, determining epigenetic divergences and evaluating fluctuating asymmetry. The time course of tooth eruption and replacement in the Asiatic wild ass is described with regard to its use for age determination. …

Territorial Behaviour Of Kiang (Equus Kiang Moorcroft, 1841) In Ladakh (India), Natalia V. Paklina, Chris Van Orden

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

The observations of kiang behavior were made in Navokar Valley northeast of Tso Kar Lake (Ladakh, India) between July 30 and November 22, 2001. In the breeding season (end of July until the end of August) adult kiang males kept not overlapping, protected territories (about 10 km²), and marked by single defecation and urination marks. There were adult females with and without offspring on the territories (up to 12 animals, including the male). The distance between male and females on the territories was usually hundred times bigger, then a distance between stallion and his harem in horses. Females …

Semi-Wild Population Of Kulans In The Bukhara Breeding Centre And Their Co-Habitation With Przewalski’S Horses, Karim Bahloul, Olga B. Pereladova, Natalia V. Soldatova, Ekaterina V. Sidorenko, Antoine J. Sempere

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

Asiatic wild asses and Przewalski's horses initially inhabited steppe, semi-desert and desert areas, but Przewalski's horses became extinct in the wild, and kulans are under threat of disappearance. The Bukhara Breeding Centre (Uzbekistan) was created in 1976 for conservation and reintroduction of wild ungulate species. In 1977-1978, five kulans (two males and three females) from Barsa-Kelmes Island on the Aral lake were introduced to the reserve. The group increased to 25-30 animals in 1995-1998, when five Przewalski's horses from Moscow and St. Petersburg zoos were introduced to the same territory. We analyzed the home ranges, preferred habitats and social interactions …

Social Networks In Wild Asses: Comparing Patterns And Processes Among Populations, Daniel I. Rubenstein, Siva Sundaresan, Ilya Fischhoff, David Saltz

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

Asiatic wild asses inhabit some of the most arid environments in the world. All live in fissionfusion societies, but demography varies and the deserts in which they live often differ in subtle ways. Characterizing details of social structure of wild ass populations has been a challenge and has made it difficult to determine causes and consequences of any differences that might exist. We use network theory to compare the social structures of two populations of Asiatic asses/ onagers inhabiting the Negev desert, Israel and khur of the Little Rann of Kuch, India and show that populations differ in important structural …

An Overview On The State Of Equus Hemionus In Whole China, Weikang Yang

The wild ass in China is divided into two species: Gobi khulan (Equus hemionus) and kiang (Equus kiang). Maps and charts of the distribution and population sizes in China and Mongolia of each species are shown from the 1980s through the early 2000s.

Possible Use Of Foresight, Understanding, And Planning By Wolves Hunting Muskoxen, L. David Mech

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

On Ellesmere Island in 2006, arctic wolves (Canis lupus arctos) were observed making a two-pronged approach to a herd of muskoxen (Ovibos moschatus) and, on another occasion, ambushing muskoxen. Both observations seemed to provide evidence that the wolves were using foresight, understanding, and planning. Although the possible use of insight and purposiveness has been documented in captive wolves, the present report is one of the few to document the possibility that freeranging wolves use these other three mental processes.

En 2006, sur l’île Ellesmere, des loups arctiques (Canis lupus arctos) ont été observés en …

Annual Arctic Wolf Pack Size Related To Arctic Hare Numbers, L. David Mech

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

During the summers of 2000 through 2006, I counted arctic wolf (Canis lupus arctos) pups and adults in a pack, arctic hares (Lepus arcticus) along a 9 km index route in the area, and muskoxen (Ovibos moschatus) in a 250 km² part of the area near Eureka (80° N, 86° W), Ellesmere Island, Nunavut, Canada. Adult wolf numbers did not correlate with muskox numbers, but they were positively related (r² = 0.89; p < 0.01) to an arctic hare index. This is the first report relating wolf numbers to non-ungulate prey.

Pendant les étés 2000 à 2006, j’ai compté les jeunes loups arctiques et les adultes (Canis lupus arctos …

Chlorophacinone Baiting For Belding’S Ground Squirrels, Craig A. Ramey, George H. Matschke, Richard M. Engeman

United States Department of Agriculture Wildlife Services: Staff Publications

The efficacy of using 0.01% chlorophacinone on steam-rolled oat (SRO) groats applied in CA alfalfa by spot-baiting/hand baiting around burrow entrances (~11.5 g) to control free-ranging Belding's ground squirrels (Spermophilus beldingi) were compared in 6 randomly assigned square treatment units (TUs). Four TUs were given the rodenticide and 2 treated with placebo bait. Each TU was a 0.4 ha square surrounded by a similarly treated 5.5 ha square buffer zone. Baits were applied on May 13 and re-applied, on May 20 and May 22, after 7 days of un-forecasted cool wet weather greatly reduced their above ground activity. Pesticide (EPA …

Evaluation Of Habitat Enhancement Structure Use By Spotted Bass, Stanley L. Proboszcz, Christopher S. Guy

The Prairie Naturalist

Habitat enhancement is a common and effective method used to positively influence fish populations. However, there is a paucity of speciesspecific evaluations of stream habitat enhancement structures for warmwater fishes. We evaluated use of half-log, rootwad enhancement structure, and simulated undercut bank (LUNKERS) by adult and juvenile spotted bass (Micropterus punctulatus) in natural and experimental streams. Enhancement structures were installed in Otter Creek, Kansas. Adult spotted bass use of natural and enhancement structure was documented weekly during summer and fall of 2001 and 2002 with radiotelemetry. Mean total length (TL) of adult fish was 292 mm (SE = …

Biology Faculty Publications

Karyotypes of eight species of Leptodactylus (Anura, Leptodactylidae) with a description of a new karyotype for the genus. Eight species of the Neotropical genus Leptodactylus were karyologically studied: seven of them (L. gracilis, L. mystacinus, L. petersii, L. pustulatus, L. macrosternum, L. ocellatus, L. labyrinthicus) presented 2n=22 and L. silvanimbus showed a distinctive karyotype with 2n=24. Nucleolar organizer regions (Ag-NORs) were detected in two different pairs of chromosomes: pair 4 at the proximal region of the long arm of one individual of L. mystacinus from São Paulo state and of L. petersii; and …

Genetic Resolution Of The Enigmatic Lesser Antillean Distribution Of The Frog Leptodactylus Validus (Anura, Leptodactylidae), Keneth Yanek, W. R. Heyer, Rafael O. De Sá

Biology Faculty Publications

Leptodactylus validus has an unusual distribution, inhabiting Trinidad, Tobago, and the Lesser Antilles, but not the mainland of South America. This distribution is inconsistent with other distribution patterns observed for these islands. Although slight variation in adult morphology has been observed among the different island populations of L. validus, call data suggest the presence of a single species. Calls of L. pallidirostris from Venezuela and Brazil suggested that this taxon might be conspecific with L. validus. Sequence data from the 12S and 16S mt rDNA genes indicate that L. validus represents a single species throughout its distribution and is conspecific …

The Effects Of The Makgadikgadi Wildlife Fence On Cattle Populations And Local Cattle Industry, Jenny Hazelhurst, Elliot Vander Kolk

Independent Study Project (ISP) Collection

This study was conducted to determine the effects of the erection of the Makgadikgadi wildlife fence along the western border of the Makgadikgadi Pans National Park on cattle populations and livestock owners to the west of the fence. Cattle foraging behavior and movement patterns were recorded using GPS and focal observation methods to determine resource use and pressures affecting the populations. Interviews were also conducted in the area of Meno-a-Kwena camp to examine the effects of the fence on the economics of the local cattle industry. Signs of resource stress were found in the continued selection of poor quality forage, …

Rana Ocellata Linnaeus, 1758 (Currently Leptodactylus Ocellatus; Amphibia, Anura): Proposed Conservation Of Usage Of The Specific Name By The Designation Of A Neotype, W. Ronald Heyer, Ulisses Caramaschi, Rafael O. De Sá

Biology Faculty Publications

The purpose of this application, under Article 75.6 of the Code, is to conserve the usage of the specific name of Rana ocellata Linnaeus, 1758 for a species of leptodactylid frog from South America by the designation of a neotype. Prevailing usage of the name is threatened by the identity of the type specimen which is a different species than that which is currently known as Leptodactylus ocellatus. It is proposed that all name-bearing types be set aside and a neotype designated in accord with prevailing usage.

Artificial Burrows And The Deer Mouse: Do Number Of Entrances Influence Use?, Glennis A. Kaufman, Donald W. Kaufman

The Prairie Naturalist

We examined use of artificial burrows by the deer mouse (Peromyscus maniculatus) in mixed grass prairie in north central Kansas. We predicted differential use of burrows, such that the deer mouse would prefer two entrance burrows in non-winter months when predatory snakes were active, but prefer one entrance burrows in winter when cold, windy conditions existed. We installed 20 pairs of artificial burrows (one single entrance and one double entrance) in summer 1988. We examined these burrows on seven dates from autumn 1988 to autumn 1989. All mice (n = 70) used two entrance burrows at least …

Anadromous Rainbow Smelt And Tomcod In Connecticut: Assessment Of Populations, Conservation Status, And Need For Restoration Plan, Heather A. Fried, Eric T. Schultz

EEB Articles

(beginning of rainbow smelt executive summary)

Evidence indicates that anadromous rainbow smelt (Osmerus mordax) populations in Connecticut and elsewhere in the northeast United States have severely declined. Several sampling programs have documented declines in Connecticut’s smelt populations over the last three decades (Marcy 1976a, Marcy 1976b, Millstone Environmental Laboratory 2005). Similar declines have also been documented in the Hudson River (ASA Analysis & Communication 2005) and in Massachusetts (personal communication, Brad Chase, MA Division of Marine Fisheries 2004). Recreational and commercial fisheries in the region for this species have virtually ceased (Blake and Smith 1984). The Connecticut Fish Advisory Committee …

The Distress Calls Of Leptodactylus Chaquensis Cei, 1950 And Leptodactylus Elenae Heyer, 1978 (Anura: Leptodactylidae), José M. Padial, Rafael O. De Sá, Ignacio De La Riva

Biology Faculty Publications

We describe the distress calls of Leptodactylus chaquensis and Leptodactylus elenae. They each consist of a single, long, tonal sound with complex harmonic structure and complex frequency modulation. The distress calls of both species are different from their respective advertisement calls. Moreover, there are also clear interspecific differences. Harmonic frequencies in L. elenae are higher, there are fewer emphasized harmonics and the call is shorter and repeated at a higher rate (sometimes paired) than the call of L. chaquensis. Call duration, call rate, and position of the dominant harmonic change with the strength of the stimulus that the …

Assessment Of Anadromous Alewife And Blueback Herring Populations In Connecticut Coastal Streams And Connecticut River Tributaries, Justin P. Davis, Eric T. Schultz

EEB Articles

Alewife (Alosa pseudoharengus) and blueback herring (A. aestivalis) occur in anadromous populations that have a largely overlapping distribution from Florida to Newfoundland (Loesch 1987). Anadromous populations of these species are commonly collectively referred to as “river herring”. Adults inhabit coastal shelf waters until sexual maturity is reached at age 3-5 (Neves 1981). Sexually mature individuals make spawning migrations, commonly referred to as “runs”, into freshwater systems during spring months (Loesch 1987). Spawners can survive and return to spawn in subsequent years (Mullen et al. 1986). Juveniles reside in freshwater for 3-7 months, at which time they undertake a gradual migration …

Prevalence And Serovars Of Salmonella In The Feces Of Free-Ranging White-Tailed Deer (Odocoileus Virginianus) In Nebraska, David G. Renter, David P. Gnad, Jan M. Sargeant, Scott E. Hygnstrom

School of Natural Resources: Faculty Publications

To determine the prevalence and serovars of Salmonella in free-ranging deer, we cultured feces from white-tailed deer (Odocoileus virginianus) harvested by hunters during a regular firearm season in southeastern Nebraska (USA). We recovered Salmonella from 5 (1%; 95% confidence interval: 0.37– 2.20%) of 500 samples and identified four different Salmonella enterica serovars [Litchfield (1), Dessau (1), Infantis (2), and Enteritidis (1)]. Although the prevalence of Salmonella in free-ranging deer appears to be low, the serovars recovered are known to be pathogenic to humans and animals.

The Natural History And Thermal Ecology Of A Population Of Spotted Turtles (Clemmys Guttata) And Wood Turtles (Glyptemys Insculpta) In West Virginia, Ariana N. Breisch

Theses, Dissertations and Capstones

An ecological study was conducted from 19 March 2001 to 2 April 2003 on a population of Spotted Turtles (Clemmys guttata) and Wood Turtles (Glyptemys insculpta) in West Virginia. Live-trapping, mark-recapture, radio telemetry and temperature data logging techniques were used to gather information on morphometrics, capture success, movements, home range, behavior, and thermal regime during activity and over-wintering seasons. Twenty-one Spotted Turtles were captured 260 times. Population structure was 42.9% juvenile, 38.1% male, and 19.0% female. Mean home range was 0.52 ha. Fifty Wood Turtles were captured 230 times. Juveniles were 36%, and males and females were 32% each. Mean …

Terpenes And Carbohydrate Source Influence Rumen Fermentation, Digestibility, Intake, And Preference In Sheep, J. J. Villalba, F. D. Provenza, K. C. Olson

Green Canyon Environmental Research Area, Logan Utah

We hypothesized that toxins and nutrients in foods interact to influence foraging behavior by herbivores. Based on this hypothesis we predicted that 1) terpenes in big sagebrush (Artemisia tridentata) influence intake and preference in sheep for diets varying in sources of nonstructural (barley grain) and structural (sugar beet pulp) carbohydrates, and 2) these effects are due to the differential effects of terpenes on fermentation products and apparent digestibility of each class of carbohydrates. Lambs were fed 2 isoenergetic and isonitrogenous diets with varying proportions of the same ingredients (beet pulp- and barley grain-based diet) or offered a choice between the …
