Title | The contingencies of group size and vigilance | Type | Miscellaneous | ||

Abstract | Background: Predation risk declines non-linearly with one's own vigilance and the vigilance of others in the group (the 'many-eyes' effect). Furthermore, as group size increases, the individual's risk of predation may decline through dilution with more potential victims, but may increase if larger groups attract more predators. These are known, respectively, as the dilution effect and the attraction effect. Assumptions: Feeding animals use vigilance to trade-off food and safety. Net feeding rate declines linearly with vigilance. Question: How do the many-eyes, dilution, and attraction effects interact to influence the relationship between group size and vigilance behaviour? Mathematical methods: We use game theory and the fitness-generating function to determine the ESS level of vigilance of an individual within a group. Predictions: Vigilance decreases with group size as a consequence of the many-eyes and dilution effects but increases with group size as a consequence of the attraction effect, when they act independent of each other. Their synergetic effects on vigilance depend upon the relative strengths of each and their interactions. Regardless, the influence of other factors on vigilance – such as encounter rate with predators, predator lethality, marginal value of energy, and value of vigilance – decline with group size. |

Abstract | In accordance with order of the Ministry of Nature and Tourism, zoologists of our association have made surveys in three ways such as reasons why snow leopards attack domestic animals, “Snow leopard” trial operation to count them and illegal hunting in territories of Khovd, Gobi-Altai, Bayankhongor, Uvurkhangai and Umnugobi provinces from September 2009 to January 2010. As result of these surveys it has made the following conclusions in the followings: Reason to hunt them illegally: the principal reason is that administrative units have been increased and territories of administrative units have been diminished. There have been four provinces in 1924 to 1926, 18 since 1965, 21 since 1990. Such situation limits movements of herdsmen completely and pastures digressed much than ever before. As result of such situation, 70% of pastures become desert. Such digression caused not only heads of animals and also number of species. Guarantee is that birds such as owls, cuckoo, willow grouse in banks of Uyert river, Burkhanbuudai mountain, located in Biger soum, Gobi-Altai province, which are not hunted by hunters, are disappearing in the recent two decades. For that reason we consider it is urgently necessary for the government to convert administrative unit structures into four provinces. This would influence herdsmen moving across hundreds km and pastures could depart from digression. Second reason: cooperative movement won. The issues related to management and strengthening of national cooperatives, considered by Central Committee of Mongolian People's Revolutionary Party in the meeting in March 1953 was the start of cooperatives' movement. Consideration by Yu. Tsedenbal, chairman of Ministers Council, chairman of the MPRP, on report “Result of to unify popular units and some important issues to maintain entity management of agricultural cooperatives” in the fourth meeting by the Central Committee of Mongolian People's Revolutionary Party /MPRP/ on December 16-17, 1959, proclaimed complete victory of cooperative. At the end of 1959, it could unify 767 small cooperative into 389 ones, unify 99.3 % of herdsmen and socialize 73.3 % of animals. The remaining of animals amount 6 million 163 thousands animals, and equals to 26.7% of total animals. This concerned number of animals related to the article mentioned that every family should have not more that 50 animals in Khangai zone and not more 75 animals in Gobi desert. It shows that such number could not satisfy needs of family if such number is divided into five main animals in separating with reproduction animals and adult animals. So herdsmen started hunt hoofed animals secretly and illegally in order to satisfy their meat needs. Those animals included main food of snow leopard such as ibex, wild sheep, and marmot. Third reason is that the state used to hunt ibex, which are main nutrition of snow leopards, every year. The administrative unit of the soum pursued policy to hunt ibex in order to provide meat needs of secondary schools and hospitals. That's why this affected decrease of ibex population. Preciously from 1986 to 1990 the permissions to hunt one thousands of wild sheep and two thousands of ibexes were hunt for domestic alimentary use every year. Not less than 10 local hunters of every soum used to take part in big game of ibexes. Also they hunted many ibexes, chose 3-10 best ibexes and hid them in the mountains for their consummation during hunting. Fourth reason: hunting of wolves. Until 1990 the state used to give prizes to hunter, who killed a wolf in any seasons of the year. Firstly it offered a sheep for the wolf hunter and later it gave 25 tugrugs /15 USD/. Every year, wolf hunting was organized several times especially picking wolf-cubs influenced spread and population of wolves. So snow leopard came to the places where wolves survived before and attack domestic animals. Such situation continued until 1990. Now population of ibexes has decreased than before 1990 since the state stopped hunting wolves, population of wolves increased in mountainous zones. We didn't consider it had been right since it was natural event. However population of ibexes decreased. Fifth reason: Global warming. In recent five years it has had a drought and natural disaster from excessive snow in the places where it has never had such natural disasters before. But Mongolia has 40 million heads of domestic animals it has never increased like such quantity in its history before. We consider it is not incorrect that decrease of domestic animals could give opportunities to raise population of wild animals. Our next survey is to make attempt to fix heads of snow leopards correctly with low costs. |

Abstract | China, the world's most populous country, also contains the largest number of Snow Leopards of any country in the world. But the survey and research of the snow leopard had been very little for the second half of the 20th century. Until recent years, the members of Xinjiang Snow Leopards Group (XSLG/SLT/XFC) , the Xinjiang Institute of Ecology and Geography, Chinese Academy of Sciences have been tracking down the solitary animal. The journal reporter does a face-to-face interview with professor Ma Ming who is a main responsible expert of the survey team. By the account of such conversation, we learn the achievements, advances and difficulty of research of snow leopards in the field, Tianshan and Kunlun, Xinjiang, the far west China, and we also know that why the team adopt the infrared camera to capture the animals. Last but not least professor talked about the survival menace faced by the Snow Leopards in Xinjiang. | ||||

Abstract | The World Conservation Union listed the snow leopard (Uncia uncia) as endangered in 1974. With as few as 3,500 snow leopards left in the wild, scientists placed the snow leopard on the IUCN Red List of critically endangered species shared by animals such as the giant panda and tiger. In an effort to save the snow leopard from extinction, former zoo employee Helen Freeman founded the Snow Leopard Trust in 1981. The Snow Leopard Trust works to save this elusive cat by incorporating community-based conservation projects. One of these project Leopard Enterprise (SLE), impacts poverty stricken communities in Mongolia, Kyrgyz Republic, and Pakistan. It assists over 300 families in its conservation efforts. The economic incentives provided via SLE have led participating communities not to harm the snow leopard or its prey, and to practice sustainable herding. Since the project began in 1997, the number of snow leopards harmed around the communities' territories has dropped to near zero. Additionally, the annual income of families that utilize the benefits of SLE has increased by 25% to 40%. SLE creates this economic benefit by providing the training and equipment necessary to make desirable products from the wool of herd animals. Snow Leopard Trust then purchases these handicraft items from the local people and them globally. Zoos can expand their conservation efforts by simply offering these items in their gift shops. Woodland Park Zoo (WPZ) was the first zoological institution to sell the products, and WPZ continues to generate revenue from them. SLE is a golden opportunity for zoos to increase revenue, assist poor families, and save an endangered species and fragile ecosystem. | ||||
