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 |
The modern era of wildlife and protected area conservation in Nepal began in 1973 with the passage of comprehensive legislation, and has evolved very quickly as new priorities and problems have emerged. Here we explore the legal and managerial development of conservation areas, a recently-defined category of protected area designed to promote conservation through local-level participation and development. A review of the Conservation Area Management Regulations of 1996 shows that there are several potential problems inherent in this designation. As written, the regulations move power from the government to organizations under governmental contract. Thus, management authority largely remains top-down from the standpoint of local users. We also question how well the designation will protect some sensitive wildlife species, since organizations do not have law enforcement authority under Nepalese legislation.
Despite these concerns, there have been several successful conservation area programmes in existence in Nepal since the 1980s and most of the issues addressed are surmountable with the current regulations, providing that several criteria are met. We propose that His Majesty's Government and organizations under contract develop more definitive methods of disbursing funds for local-level projects, and institute social impact assessments. In addition, more attention must be paid to wildlife law enforcement; independent assessments of important wild populations and unique habitats are needed. Finally, we discuss some broader issues that should be better addressed in Nepal and elsewhere, including cross-sectoral coordination within the government. |

Abstract |
During a six-week period in Hemis National Park, Ladakh, India, snow leopards killed 10 sheep and goats and one leopard gained access to a livestock pen and killed many of the animals inside. Dholes also killed sheep and goats, and a wolf killed a young horse. Residents routinely remove snow leopard cubs from their dens to limit future damage by this species. How to deal with the plight of the people living in the area while still protecting the endangered species are major concerns of the International Snow Leopard Trust, which manages Hemis National Park. lgh. |
