Abstract |
The annual reproductive cycle of the male snow leopard (Panthera uncia) was characterized by evaluating seminal and endocrine traits monthly. Testicular volume was greatest (P < 0.05) during the winter months when the quality of ejaculate was optimal. Ejaculate volume, total sperm concentration ml-1, motile sperm concentration per ejaculate, sperm morphology and sperm motility index were lowest during the summer and autumn months compared with the winter and spring. Peripheral LH, FSH and testosterone concentrations were also lowest during the summer months, increasing during the autumn just before the increase in semen quality, and were maximal during the winter months. There was a direct relationship (P < 0.01) between: (1) testosterone and testicular volume, total sperm concentration ml-1, motile sperm concentration per ejaculate and ejaculate volume, and (2) LH and testicular volume and motile sperm concentration per ejaculate. In summary, although spermatozoa were recovered throughout the year, optimal gamete quality was observed during the winter and spring. Although previous studies in felids have demonstrated seasonal effects on either seminal or endocrine traits, this is the first study to demonstrate a distinct effect of season on both pituitary and testicular function. |

Abstract |
Melengestrol acetate (MGA) is the most widely used contraceptive in zoo felids, but the mechanism of contraception and the pathologic effects have not been investigated. For this study, the effects of MGA on folliculogenesis were assessed, and the association of MGA with ovarian lesions was evaluated. Comparisons were made among the histopathologic findings in the ovaries from 88 captive wild felids (representing 15 species) divided into three groups: 37 currently contracepted with MGA, eight previously exposed to MGA, and 43 never contracepted. Ninety-one percent of the felids evaluated had tertiary follicles, and no differences were noted between contracepted and uncontracepted cats. Some MGA-contracepted cats also had corpora lutea indicating recent ovulation. These results indicate that folliculogenesis is not suppressed by current doses of MGA and ovulation occurred in some cats. Therefore, the contraceptive actions of MGA do not occur by suppressing folliculogenesis, and MGA-contracepted felids likely have endogenous estrogens that may confound progestin effects on the uterus. Cystic rete ovarii was the most common pathologic finding, but they were not more prevalent in MGA-contracepted cats. These findings indicate that MGA is not associated with ovarian disease, including ovarian cancer, in contrast to the uterine lesions noted in MGA-treated cats. |

Abstract |
Degenerative spinal disorders, including intervertebral disc disease and spondylosis, seldom occur in domestic cats. In contrast, a retrospective study of 13 lions (Panthera leo), 16 tigers (Panthera tigris), 4 leopards (Panthera pardis), 1 snow leopard (Panthera uncia), and 3 jaguars (Panthera onca) from the Knoxville Zoo that died or were euthanatized from 1976 to 1996 indicated that degenerative spinal disease is an important problem in large nondomestic felids. The medical record, radiographic data, and the necropsy report of each animal were examined for evidence of intervertebral disc disease or spondylosis. Eight (three lions, four tigers, and one leopard) animals were diagnosed with degenerative spinal disease. Clinical signs included progressively decreased activity, moderate to severe rear limb muscle atrophy, chronic intermittent rear limb paresis, and ataxia. The age at onset of clinical signs was 10-19 yr (median = 18 yr). Radiographic evaluation of the spinal column was useful in assessing the severity of spinal lesions, and results were correlated with necropsy findings. Lesions were frequently multifocal, included intervertebral disc mineralization or herniation with collapsed intervertebral disc spaces, and were most common in the lumbar area but also involved cervical and thoracic vertebrae. Marked spondylosis was present in the cats with intervertebral disc disease, presumably subsequent to vertebral instability. Six of the animals' spinal cords were examined histologically, and five had acute or chronic damage to the spinal cord secondary to disc protrusion. Spinal disease should be suspected in geriatric large felids with decreased appetite or activity. Radiographic evaluation of the spinal column is the most useful method to assess the type and severity of spinal lesions. |

Abstract |
The distribution and status of large mammals was surveyed in a 15 000 km2 study area in Ladakh, India. Snow leopard Panthera uncia, wolf Canis lupus, ibex Capra ibex and bharal Pseudois nayaur have an almost continuous distribution throughout; Ladakh urial Ovis vignei, Tibetan argali Ovis ammon, wild ass Equus kiang and brown bear Ursus arctos have a limited distribution. Snow leopard prefer lower altitudes and rocky, undisturbed areas. Ibex and bharal occupy similar rocky habitats but their ranges are mostly separate, with a small area of overlap. The Ladakh urial shows signs of recovery from an earlier decline. Natural resources are widely used for fuel, fodder and grazing, but favourable factors include a low human population, low level of hunting and the existence of some uninhabited and undisturbed areas. A comprehensive Protected Area Network has been proposed. |

Abstract |
A syndrome of multiple congenital ocular anomalies in a litter of domestic kittens is described which appears identical to the multiple colobomatous syndrome described in captive Snow Leopards. The lesions varied between kittens in the litter, but ranged from microphthalmos with blindness to mild alterations in the lateral lid margins that resulted in trichiasis. The syndrome of eyelid agenesis in the domestic cat may encompass a broad range of congenital ocular lesions and multiple siblings, but the cause and mechanism of lesion formation is unknown. |

Abstract |
As an important part of the ecosystem in the world, the wild are highly sensitive to impel the public to pay an increasing attention to the vertebrates and their habitats. The region from Xinjiang to Central Asian countries and from north China to Mongolia, explored less by zoologists. The region is mainly consisted of deserts and high mountain ranges many lakes and rivers that provide the suitable habitats for wildlife. These are actually unknown. Conservation in the modern sense is a very important part of development, especially in the Western Development of China. This paper deals with the species diversity and vertebrates' conservation in Xinjiang. Since 1980, over 20 Iocal nature reserves and 4 nationaI nature reserves have been established in Xinjiang. There are about 700 vertebrate species (in 5 classesœª37 ordersœr97 familiesœª196 genera) in Xinjiang. These cover about 134 species of mammalsœª392® 430 species of birdsœr40® 45 species of reptilesœª6® 7 species of amphibians and 93® 120 fishes. With the rapid economic development, some protected areas exist only in name. The areas are not only havens for wild species, but also maintain ecological benefits. Xinjiang is a very special region in China. The wild animals are different from those in other provinces along the east coast and in the interior. There are many questions about the conservation of wild animals in Xinjiang, e.g. the threatened species distinguishing, distribution and management, etc. So the paper is for reference only to the Great Development of Western China. |

Abstract |
Prior to the last two decades of conflict, Afghanistan's Wakhan Corridor was considered an important area for conservation of the wildlife of high altitudes. We conducted an assessment of the status of large mammals in Wakhan after 22 years of conflict, and also made a preliminary assessment of wildlife trade
in the markets of Kabul, Faizabad and Ishkashem. The survey confirmed the continued occurrence of at least eight species of large mammals in Wakhan, of which the snow leopard Uncia uncia and Marco Polo sheep Ovis ammon are globally threatened. We found evidence of human-wildlife conflict in Wakhan due to livestock depredation by snow leopard and wolf Canis lupus. Large mammals are hunted for meat, sport, fur, and in retaliation against livestock depredation. The fur trade in Kabul is a threat to the snow leopard, wolf, lynx Lynx lynx and common leopard Panthera pardus. |
