Abstract |
Noninvasive fecal assays were used to study steroid metabolism and ovarian activity in several felid species. Using the domestic cat (Felis catus) as model, the excretory products of injected [14C]estradiol (E2) and [14C]progesterone (P4) were determined. Within 2 days, 97.0 +/- 0.6% and 96.7 +/- 0.5% of recovered E2 and P4 radioactivity, respectively, was found in feces. E2 was excreted as unconjugated estradiol and estrone (40%) and as a non-enzyme- hydrolyzable conjugate (60%). P4 was excreted primarily as non-enzyme- hydrolyzable, conjugated metabolites (78%) and as unconjugated pregnenolone epimers. A simple method for extracting fecal steroid metabolites optimized extraction efficiencies of the E2 and P4 excretion products (90.1 +/- 0.8% and 87.2 +/- 1.4%, respectively). Analysis of HPLC fractions of extracted fecal samples from the radiolabel-injected domestic cats revealed that E2 immunoreactivity coincided primarily with the unconjugated metabolized [14C]E2 peak, whereas progestogen immunoreactivity coincided with a single conjugated epimer and multiple unconjugated pregnenolone epimers. After HPLC separation, similar immunoreactive E2 and P4 metabolite profiles were observed in the leopard cat (F. bengalensis), cheetah (Acinonyx jubatus), clouded leopard (Neofelis nebulosa), and snow leopard (Panthera uncia). Longitudinal analyses demonstrated that changes in fecal E2 and P4 metabolite concentrations reflected natural or artificially induced ovarian activity. For example, severalfold increases in E2 excretion were associated with overt estrus or exogenous gonadotropin treatment, and elevated fecal P4 metabolite concentrations occurred during pregnant and nonpregnant (pseudopregnant) luteal phases. Although overall concentrations were similar, the duration of elevated fecal P4 metabolites during pseudopregnancy was approximately half that observed during pregnancy. In summary, steroid metabolism mechanisms appear to be conserved among these physically diverse, taxonomically related species. Results indicate that this hormone-monitoring approach will be extremely useful for elucidating the hormonal regulatory mechanism associated with the reproductive cycle, pregnancy, and parturition of intractable and endangered felid species. |

Abstract |
I studied snow leopards (Panthera uncia) and blue sheep (Pseudois nayaur) in Manang District, Annapurna Conservation Area, Nepal, to estimate numbers and analyze predator-prey interactions. Five to seven adult leopards used the 10-5-km-2 study area, a density of 4.8 to 6.7 leopards/100 km-2. Density of blue sheep was 6.6 10.2 sheep/km-2, and biomass density was 304 kg/km-2. Estimated relative biomass consumed by snow leopards suggested that blue sheep were the most important prey; marmots (Marmota himalayana) also contributed significantly to the diel of snow leopards Snow leopards in Manang were estimated to harvest 9-20% of total biomass and 11-24% of total number of blue sheep annually. Snow leopard: blue sheep ratio was 1:114-1:159 on a weight basis, which was considered sustainable given the importance of small mammals in the leopard's diet and the absence of other competing predators. |

Abstract |
Full Text: In 1991, Dr Andrzej Kruszewicz of the Institute of Ecology of the Polish Academy of Sciences saw a “quite fresh” snow leopard skin on sale by a Russian in a Warsaw market for three million Polish zlotys ($300). A few weeks later he saw another skin in a shop in the centre of Warsaw. In spring 1992, Marcin Waslawski from the Institute of Geography saw a snow leopard skin in the same market for the equivalent of $200. The seller was an Asian from a former Soviet Republic. In summer 1992, Wajrak himself saw a snow leopard skin in a hunters' shop in Warsaw and in winter saw one in the home of a Polish hunter, who said it was a gift from a Mongolian friend. In winter 1994, a student from Britain saw a Polish long coat of snow leopard skins in Bialowieza. Wajrak saw a skin in a Warsaw shop, which the owner said was 15-20 years old; he got it from a Polish diplomat who had been in Mongolia and had three snow leopard skins. The skin was priced at the equivalent of $1,000. Wajrak added that he had been told that it was possible to buy tiger skins from Russians in Poland and he was trying to find one; I have not heard from him since. |

Abstract: The National Fish and Wildlife Foundation (NFWF) which is a conservation organization created in 1984 aims to conserve the species on an international context before they are endangered which will enable a more effective conservation procedure. The NFWF has addressed the causes of endangered species in India and South Asia such as the tiger, Indian wolf and the snow leopard and has supported the conservation efforts of the Siberian tiger. It has cooperated with multi-national organizations to evaluate the best strategy that could be adopted to prevent a future extinction of several species and has supported CITES programs |

Abstract |
Public attitudes towards snow leopard Panthera uncia predation of domestic livestock were investigated by a questionnaire survey of four villages in snow leopard habitat within the Annapurna Conservation Area, Nepal Most local inhabitants were subsistence farmers, many dependent upon yaks, oxen, horses and goats, with an average livestock holding of 26.6 animals per household. Reported losses to snow leopards averaged 0.6 and O. 7 animals per household in two years of study, constituting 2.6% of total stockholding but representing in monetary terms almost a quarter of the average annual Nepali national per capita income. Local people hem strongly negative attitudes towards snow leopards and most suggested that total extermination of leopards was the only acceptable solution to the predation problem. Snow leopards were reported to be killed by herdsmen in defence of their livestock. The long-term success of snow leopard conservation programmes may depend upon the satisfactory resolution of the predation conflict. Some possible ways of reducing predation losses are also discussed. |

Abstract |
Changes in economy and land use are under way in the Indian Transhimalayan region of Ladakh, creating both negative and positive prospects for wildlife conservation in this sparsely populations and previously remote area. New livestock breeds, irrigation developments, farming practices, foreign tourists, and a large military presence are changing the way people view and use the mountainous land that surrounds them. With only 0.3% of the land currently arable, changes in wildlife and natural resource conservation are most apparent on Ladakh's extensive rangelands which are apparently undergoing a redistribution of use associated with social changes and recently introduced animal husbandry and farming practices. International endangered species such as the snow leopard, several wild ungulates, and the black-necked crane provide special incentive for conservation efforts in what are some of the best remaining natural areas in the mountainous regions to the north of the Himalayan crest. The success of newly created protected areas for wildlife conservation in Ladakh rests on an understanding of the effects of various development directions, a commitment to environmentally sensitive development amid the many competing demands on Ladakh's natural resources, conservation laws appropriate to human needs, and a clear recognition that solutions can be neither directly adaptable from other mountainous areas nor even widely applicable across the Himalayan region. |

Abstract |
Electroejaculates from eight snow leopards were used to determine how the motility of spermatozoa was influenced by (i) type of media (Ham's F10, PBS, human tubal fluid or RPMI-1640); (ii) holding temperature (23 degrees C versus 37 degrees C); (iii) washing of spermatozoa and (iv) a sperm metabolic enhancer, pentoxifylline. The duration of sperm motility was assessed by evaluating samples in each treatment every hour for 6 h and a sperm motility index (a value combining percentage sperm motility and rate of forward progression) calculated. Spermatozoa from the Ham's F10, PBS and PBS plus pentoxifylline treatments were also co-incubated with zona-intact, domestic cat eggs that were fixed and evaluated for spermatozoa bound to the zona pellucida, penetrating the outer and inner layers of the zona pellucida and within the perivitelline space. During the 6 h co-incubation, the sperm motility index in PBS with pentoxifylline was greater (P < 0.05) than in PBS alone which, in turn, was greater (P < 0.05) than in the other three test media. Washing the spermatozoa enhanced (P < 0.05) motility in both PBS and PBS plus pentoxifylline relative to unwashed samples, but there was no effect (P > 0.05) of holding temperature. Pentoxifylline supplementation enhanced (P < 0.05) the proportion of cat eggs with bound, but not penetrated, snow leopard spermatozoa in the inner layer of the zona pellucida, and there were no spermatozoa in the perivitelline space.(ABSTRACT TRUNCATED AT 250 WORDS) |

Abstract |
Of the many problems facing the republics of Central Asia and Kazakhstan after the break-up of the USSR, poaching of endandered animals is of particular concern. Everything is up for sale through the black market, networks of acquaintances, middlemen or even advertisements in the newspapers: horns, skins, mounted trophies, animal parts for traditional medicine. Interest in snow leopard and Turkestan lynx (Lynx lynx isabellinus Blyth), and skins and horns from mountain sheep and goats sharply increased in 1992-93, and prices grew unusually high. |
