Xu, F., Ming, M., Yin, S. -jing, & Munkhtsog, B. (2006). Autumn Habitat Selection by Snow Leopard (Uncia uncia) in Beita Mountain, Xinjiang, China.
Abstract: Habitat selection of Snow Leopard ( Unica unica) in Beita Mountain of the Altay Mountain system in northeast Xinjiang was conducted from September to October 2004. Six habitat features of 59 sites used by Snow Leopard and 30 random plots were measured by locating 15 transects surveys in the study area . Vanderploge and Scaviaps selectivity index was used to assess Snow Leopardps selection for the different habitat parameters. Principal Component Analysis was used as the primary factor . The results indicated that Snow Leopard preferred the altitude between 2000 – 2 200 m and avoided 2 600 – 3 000 m ; selected cliff base , ridgeline and avoided hillside and valley bottom ; utilized the shrub and rejected the forest ; selected the nongrazing area and avoided the slightly broken region ; preferred north orientation and rejected the south orientation. The results show that grazing status , vegetation type , topography and the ruggedness are the primary factors for the habitat selection of Snow Leopard.

Graham, L. H., Goodrowe, K. L., Raeside, J. I., & Liptrap, R. M. (1995). Non-invasive monitoring of ovarian function in several felid species by measurement of fecal estradiol-17-beta and progestins. Zoo Biology, 14(3), 223–237.
Abstract: An extraction and assay procedure to measure fecal estradiol-17-beta and progestin concentrations in several cat species was developed and validated for use for noninvasive monitoring of ovarian function. Fecal samples were collected over a range of 3-20 months from female tigers (three), lions (three), snow leopards (three), cheetahs (two), caracals (two), and domestic cats (five). Samples were extracted with 90% methanol, lipids removed with petroleum ether, and the estradiol and progestins in the methanol measured by radioimmunoassay (RIA). High Performance Liquid Chromatography (HPLC) fractionation and subsequent RIA of the fractions indicated that the estradiol-17-beta antiserum cross-reacted primarily with estradiol-17-beta in the feces of lions and tigers and was assumed to be specific for estradiol-17-beta in the feces of other species as well. However, there were several immunoreactive compounds, presumably progesterone metabolites, excreted in the feces which varied both quantitatively and qualitatively among species. The behavior of tigers, lions, cheetahs, and caracals was visually monitored during the collection period and frequency of sexual behaviors was positively correlated with increases in fecal estradiol in all species observed. The mean fecal estradiol-17-beta peaks were as follows: tigers, 128.0 +- 13.1; lions, 186.0 +- 14.8; snow leopards, 136.7 +- 15.9; cheetahs, 140.9 +- 9.0; caracals, 24.5 +- 4.0; and domestic cats 158.9 +- 19.3 ng/gm. Fecal progestin concentrations rose significantly (P lt 0,001) only after breeding or during pregnancy and were as follows: tigers, 5.6 +- 0.6; lions, 1.9 +- 0.1; cheetahs, 8.4 +- 1.1; and caracals, 2.4 +- 0.4 mu-g/gm. Fecal progestins were elevated for one-half to two-thirds of the gestation length during presumed pseudopregnancy but remained elevated throughout successful pregnancies. These results suggest that ovarian function can be monitored noninvasively in the family Felidae by the measurement of fecal estradiol-17-beta and progestin concentrations.

Abstract: Considerable efforts have been devoted to conserving the snow leopard Panthera uncia in recent years, but progress has inevitably been slow due to the difficulties of studying a sparsely distributed, secretive and endangered species in often isolated mountainous terrain. Although knowledge about the species overall distribution in the highlands of Central Asia still remains fragmenatry, it is important to briefly examine all the available information in order to review measures taken to date to conserve the species through the protected areas network. The purpose of this paper is to examine the distribution and status of protected areas inhabited or visited by snow leopard in relation to the species' distribution and highlight deficiences in the present network.

Pfeil, A., Lucker, H., & Pfeil, I. (2004). Leiomyoma in the urinary bladder of a female snow leopard (Uncia uncia, Schreber, 1776). Tier„rztliche Praxis Kleintiere, 32(1), 40–44.
Abstract: Summary
A leiomyoma of the urinary bladder in a 14-year-old female snow leopard exhibiting bloody vaginal discharge was removed by partial cystectomy. Gravel (struvite) was found in the urine of the inflammatory bladder. Additionally ovario-hysterectomy was performed. Histological findings showed a glandular-cystic hyperplasia. Tumors of the bladder are very rare in cats. Specifically the benign tumors of the bladder very often have no clinical relevance and rarely result in bladder dysfunction. Therefore they might remain undiagnosed in many cases, particularly since the diagnostic procedure in big cats is very extensive. Leiomyoma of the bladder in snow leopards have not been described yet. The present paper describes the surgery performed, the succeeding therapy, the struvit prophylaxis, and discusses the aetiology of the leiomyoma's origin on the basis of current literature. Zusammenfassung
Bei einer 14-j„hrigen Schneeleopardin mit blutigem Vaginalausfluss wurde ein Leiomyom der Blase durch partielle Zystektomie entfernt. Im Urin und in der entzndeten Blase konnte Grieá (Struvit) nachgewiesen werden. Gleichzeitig wurde eine Ovariohysterektomie durchgefhrt. Der histologische Befund ergab eine glandul„r-zystische Hyperplasie des Endometriums. Tumoren der Harnblase sind bei Katzen sehr selten. Vor allem benigne Blasentumoren haben oft keine klinische Relevanz und fhren selten zu Blasenfunktionsst”rungen. Es ist daher m”glich, dass sie insbesondere bei Groákatzen wegen der aufwendigen Diagnostik bersehen werden. Leiomyome in der Blase sind beim Schneeleoparden bisher nicht beschrieben. In diesem Artikel werden die durchgefhrte Operation, die folgende Therapie und Struvitprophylaxe beschrieben sowie m”gliche Žtiologien der Entstehung des Leiomyoms anhand der Literatur diskutiert.

Abstract: The snow leopard has never been common, but there may be fewer than 4,000 left in its Himalayan habitat, and poaching and tourism-related development in the region could drive its numbers down further.
