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) …

Biodiversity In Space And Time: Towards A Grid Mapping For Mongolia, Michael Stubbe, Annegret Stubbe, Henrik Von Wehrden, Nayamsuren Batsaikhan, Ravčigijn Samjaa

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

In the future, grid mapping of animal and plant organisms will also play a major role in Mongolia. Based on geographical coordinates, a grid with a resolution of 100 x 100 km was created, which contained 561 cells. Methods and level of current understanding are exemplified by means of two raptors and three mammal species. This establishes a basis for an initial project, which will summarize all breeding occurrences of raptors based on all records, publications, or diary notes. For the first time, the short toed eagle was verified in Mongolia as a breeding bird in 2004. By 2006, ten …

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 …

Current Status Of The Khulan (Equus Hemionus) In The Trans-Altai Gobi, Enkhbileg Dulamtseren, Adiya Yadamjav, Dovchindorj Ganbold, Mijidorj Batmunkh

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.

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

First paragraph:

Was den unmittelbaren Anstoß für CARL HAGENBECK gab, 1901 den Import von Przewalskipferden zu initiieren, ist nicht bekannt. In seiner Autobiographie „Von Tieren und Menschen“ (1908) verweist er selbst auf eine Anregung durch den Herzog von BEDFORD (S. 212), die ihn zu diesem Unternehmen bewogen habe.

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

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

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.

Properties Of Corneal Receptors In A Teleost Fish, Paul J. Ashley, Lynne U. Sneddon, Catherine R. Mccrohan

Veterinary Science and Medicine Collection

Corneal receptors have not previously been identified in lower vertebrates. The present study describes the properties of trigeminal ganglion corneal receptors in a teleost fish, the rainbow trout (Oncoryhnchus mykiss). Out of 27 receptors, 7 were polymodal nociceptors, 6 were mechanothermal nociceptors, 2 were mechanochemical receptors and the largest group, 12, were only responsive to mechanical stimulation. No cold responsive receptors were found on the trout cornea. Mechanical and thermal thresholds were lower and receptive field diameters smaller than those of cutaneous trigeminal receptors in the trout, demonstrating greater sensitivity in the cornea. The lack of cold sensitive neurons may …

Identifying And Preventing Pain In Animals, Daniel M. Weary, Lee Niel, Frances C. Flower, David Fraser

Assessment of Animal Welfare Collection

Animals are routinely subjected to painful procedures, such as tail docking for puppies, castration for piglets, dehorning for dairy calves, and surgery for laboratory rats. Disease and injury, such as tumours in mice and sole ulcers on the feet of dairy cows, may also cause pain. In this paper we describe some of the ways in which the pain that animals experience can be recognized and quantified. We also describe ways in which pain can be avoided or reduced, by reconsidering how procedures are performed and whether they are actually required. Ultimately, reducing the pain that animals experience will require …

The Changing Concept Of Animal Sentience, Ian J. H. Duncan

Sentience Collection

A brief history of the concept of sentience is given. It is pointed out that the idea of sentience, at least in the mammals and birds, was accepted by lay people by the time of the Renaissance and before it was acknowledged by philosophers. It was not until the Enlightenment of the 18th century that philosophers started to accept the notion that animals have feelings. Towards the end of the 19th century, scientists and philosophers had developed a fairly sophisticated concept of sentience. Little consideration was given to sentience by scientists through much of the 20th century due to the …

Mother-Young Recognition In An Ungulate Hider Species: A Unidirectional Proce, Marco V.G. Torriani, Elisabetta Vannoni, Alan G. Mcelligott

Veterinary Science and Medicine Collection

Parent‐offspring recognition is usually crucial for survival of young. In mammals, olfaction often only permits identification at short range, and vocalizations are important at longer distances. Following and hiding antipredator strategies found in newborn mammals may also affect parental recognition mechanisms. We investigated mother‐offspring recognition in fallow deer, an ungulate hider species. We analyzed the structure of adult female and fawn contact calls to determine whether they are individually distinctive and tested for mother‐offspring recognition. Only females (and not fawns) have individualized vocalizations, with the fundamental frequency as the most distinctive parameter. Playback experiments showed that fawns can distinguish the …

Ordinality And Inferential Abilities Of A Grey Parrot (Psittacus Erithacus), Irene M. Pepperberg

Sentience Collection

A grey parrot (Psittacus erithacus), able to label the color of the bigger or smaller object in a pair (I. M. Pepperberg & M. V. Brezinsky, 1991), to vocally quantify ≤6 item sets (including heterogeneous subsets; I. M. Pepperberg, 1994), and separately trained to identify Arabic numerals 1–6 with the same vocal English labels but not to associate Arabic numbers with their relevant physical quantities, was shown pairs of Arabic numbers or an Arabic numeral and a set of objects and was asked for the color of the bigger or smaller one. The parrot’s success showed he (a) understood number …

Using Self-Organizing Maps To Recognize Acoustic Units Associated With Information Content In Animal Vocalizations, John Placer, C. N. Slobodchikoff, Jason Burns, Jeffrey Placer, Ryan Middleton

Veterinary Science and Medicine Collection

Kohonen self-organizing neural networks, also called self-organizing maps (SOMs), have been used successfully to recognize human phonemes and in this way to aid in human speech recognition. This paper describes how SOMS also can be used to associate specific information content with animal vocalizations. A SOM was used to identify acoustic units in Gunnison’s prairie dog alarm calls that were vocalized in the presence of three different predator species. Some of these acoustic units and their combinations were found exclusively in the alarm calls associated with a particular predator species and were used to associate predator species information with individual …

Acoustic Structures In The Alarm Calls Of Gunnison’S Prairie Dogs, C. N. Slobodchikoff, J. Placer

Veterinary Science and Medicine Collection

Acoustic structures of sound in Gunnison’s prairie dog alarm calls are described, showing how these acoustic structures may encode information about three different predator species (red-tailed hawk—Buteo jamaicensis; domestic dog—Canis familaris; and coyote—Canis latrans). By dividing each alarm call into 25 equal-sized partitions and using resonant frequencies within each partition, commonly occurring acoustic structures were identified as components of alarm calls for the three predators. Although most of the acoustic structures appeared in alarm calls elicited by all three predator species, the frequency of occurrence of these acoustic structures varied among the alarm calls for the different predators, suggesting that …

Grey Parrot (Psittacus Erithacus) Numerical Abilities: Addition And Further Experiments On A Zero-Like Concept, Irene M. Pepperberg

Sentience Collection

A Grey parrot (Psittacus erithacus), able to quantify 6 or fewer item sets (including heterogeneous subsets) by using English labels (I. M. Pepperberg, 1994), was tested on addition of quantities involving 0–6. He was, without explicit training, asked, “How many total X?” for 2 sequentially presented collections (e.g., of variously sized jelly beans or nuts) and required to answer with a vocal English number label. His accuracy suggested (a) that his addition abilities are comparable to those of nonhuman primates and young children, (b) some limits as to his correlation of “none” and the concept of zero, and (c) a …

Ethics And Welfare: Pain Perception In Fish, L. U. Sneddon

Aquaculture Collection

Fish welfare is currently a controversial subject with many scientific studies now demonstrating the possibility for fish to experience negative events such as pain, fear and stress. This has important implications in the treatment of fish during commercial and experimental procedures in terms of ethics and welfare. In this review, the evidence for pain perception in fish is considered and the repercussions for the use of fish as a research model as well as in aquaculture and largescale fisheries. These issues are discussed briefly from a welfare and ethical perspective.

Exploration And Habituation In Intact Free Moving Octopus Vulgaris, Jennifer Mather

Sentience Collection

Despite the huge numbers of studies published on the learning of cephalopod mollusks, studies on non-associative learning are scarce. We tested non-associative learning (habituation) and exploration in Octopus vulgaris in two different studies using a prey-shaped object (Study A) and inanimate objects and food objects (Study B). Study A consisted of the repeated presentation of a prey-like stimulus, which 23 subjects could only explore visually. In study B, 14 octopuses were presented two Lego blocks (one black and white with a smooth surface, one a blue "snowflake" with a rough surface) and two food items, one preferred (clams) and one …

Differential Effects Of Sodium And Magnesium Sulfate On Water Consumption By Beef Cattle, A. S. Grout, D. M. Veira, D. M. Weary, M. A. G. Von Keyserlingk, D. Fraser

Biochemistry Collection

The existing guidelines for maximum sulfate (SO₄) in cattle drinking water are based on Na2SO₄, although many water sources contain greater concentrations of MgSO₄. Two experiments compared the effect of different SO₄ salts on water consumption and fecal DM of cattle. In Exp. 1, 8 yearling heifers (initial BW = 345 ± 8 kg; mean ± SD) were watered twice daily with tapwater or water containing Na₂SO₄ or MgSO₄ at target levels of 1,500, 3,000, or 4,500 mg of SO₄/L for 2-d treatment periods separated by 2 …

Chimpanzee Theory Of Mind: Looking In All The Wrong Places?, Kristin Andrews

Sentience Collection

I respond to an argument presented by Daniel Povinelli and Jennifer Vonk that the current generation of experiments on chimpanzee theory of mind cannot decide whether chimpanzees have the ability to reason about mental states. I argue that Povinelli and Vonk’s proposed experiment is subject to their own criticisms and that there should be a more radical shift away from experiments that ask subjects to predict behavior. Further, I argue that Povinelli and Vonk’s theoretical commitments should lead them to accept this new approach, and that experiments which offer subjects the opportunity to look for explanations for anomalous behavior should …

Cortical Complexity In Cetacean Brains, Patrick R. Hof, Rebecca Chanis, Lori Marino

Veterinary Science and Medicine Collection

Cetaceans (dolphins, whales, and porpoises) have a long, dramatically divergent evolutionary history compared with terrestrial mammals. Throughout their 55–60 million years of evolution, cetaceans acquired a compelling set of characteristics that include echolocation ability (in odontocetes), complex auditory and communicative capacities, and complex social organization. Moreover, although cetaceans have not shared a common ancestor with primates for over 90 million years, they possess a set of cognitive attributes that are strikingly convergent with those of many primates, including great apes and humans. In contrast, cetaceans have evolved a highly unusual combination of neurobiological features different from that of primates. As …

In Situ Examination Of Boldness–Shyness Traits In The Tropical Poeciliid, Brachyraphis Episcopi, Culum Brown, Felicity Jones, Victoria Braithwaite

Sentience Collection

Explaining consistent variation in the behaviour of individuals in terms of personality differences is one of the cornerstones of understanding human behaviour but is seldom discussed in behavioural ecology for fear of invoking anthropomorphism. Recently, however, interest has begun to focus on identifying personality traits in animals and examining their possible evolutionary consequences. One major axis used to define personality traits is the shyness–boldness continuum. We examined boldness in an in situ experiment using fish from eight populations of the poeciliid Brachyraphis episcopi (also referred to as Brachyrhaphis episcopi). Fish from high- and low-predation regions within four streams that run …

The Use Of Transcriptomics To Address Questions In Behaviour: Production Of A Suppression Subtractive Hybridisation Library From Dominance Hierarchies Of Rainbow Trout, Lynne U. Sneddon, Javier Margareto, Andrew R. Cossins

Ethology Collection

Microarrays, or gene chips, are transforming the way that gene expression is measured by allowing us to determine the expression of thousands of genes from a sample. This gives immense power to examine gene expression on a global scale within individual animals and between animals. The scope for analysing complex animal functions at the molecular level is within our grasp. Relatively few studies have examined complex behaviours and correlated them with gene expression in the central nervous system. Here, we review the use of microarray technology in the dissection of behaviour and focus specifically on dominance status. A cDNA library …

Differential Stress Responses In Fish From Areas Of High- And Low-Predation Pressure, Culum Brown, Carolyn Gardner, Victoria Braithwaite

Aquaculture Collection

We subjected fish from regions of high and low levels of predation pressure in four independent streams to a mild stressor and recorded their opercular beat rates. Fish from low-predation areas showed higher maximum, minimum and mean opercular beat frequencies than fish from high-predation regions. The change in opercular beat frequency (scope) was also significantly greater in fish from low- than in fish from high-predation regions. Under normal activity levels, however, low predation fish showed a reduced opercular beat frequency, which may be indicative of reduced activity levels or metabolic rate. Opercular beat frequency was negatively correlated with standard length …

Number Comprehension By A Grey Parrot (Psittacus Erithacus), Including A Zero-Like Concept, Irene M. Pepperberg, Jesse D. Gordon

Sentience Collection

A Grey parrot (Psittacus erithacus) that was able to quantify 6 item sets (including subsets of heterogeneous groups, e.g., blue blocks within groupings of blue and green blocks and balls) using English labels (I. M. Pepperberg, 1994a) was tested on comprehension of these labels, which is crucial for numerical competence (K. C. Fuson, 1988). He was, without training, asked “What color/object [number]?” for collections of various simultaneously presented quantities (e.g., subsets of 4, 5, and 6 blocks of 3 different colors; subsets of 2, 4, and 6 keys, corks, and sticks). Accuracy was greater than 80% and was unaffected by …

Effects Of Predation Pressure On The Cognitive Ability Of The Poeciliid Brachyraphis Episcopi, Culum Brown, Victoria A. Braithwaite

Sentience Collection

Variable levels of predation pressure are known to have significant impacts on the evolutionary ecology of different populations and can affect life-history traits, behavior, and morphology. To date, no studies have directly investigated the impact of predation pressure on cognitive ability. Here we use a system of replicate rivers, each with sites of high- and low-predation pressure, to investigate how this ecological variable affects learning ability in a tropical poeciliid, Brachyraphis episcopi. We used a spatial task to assess the cognitive ability of eight populations from four independent streams (four high- and four low- predation populations). The fish were required …

Impact Of The Agricultural Sector On The Arkansas Economy In 2001, Jennie Popp, Gina Vickery, H. L. Goodwin Jr., Wayne Miller

AAES Research Reports and Research Bulletins

Agriculture has historically been one of Arkansas’ primary economic sectors. Agriculture is defined as the sum of agricultural production and processing activities unless otherwise specified. Agriculture contributes to the economy through direct agricultural production and value-added processing which generates economic activity in other parts of the economy.
