K., Riordan, P. (2020). Meta-replication, sampling bias, and multi-scale model selection:
A case study on snow leopard (Panthera uncia) in western China. Ecology and Evolution, , 1–27.
Abstract: Replicated multiple scale species distribution models (SDMs)
have become increasingly important to identify the correct variables
determining species distribution and their influences on ecological
responses. This study explores multi-scale habitat relationships of the
snow leopard (Panthera uncia) in two study areas on the Qinghai–Tibetan
Plateau of western China. Our primary objectives were to evaluate the
degree to which snow leopard habitat relationships, expressed by
predictors, scales of response, and magnitude of effects, were
consistent across study areas or locally landcape-specific. We coupled
univariate scale optimization and the maximum entropy algorithm to
produce multivariate SDMs, inferring the relative suitability for the
species by ensembling top performing models. We optimized the SDMs based
on average omission rate across the top models and ensembles’ overlap
with a simulated reference model. Comparison of SDMs in the two study
areas highlighted landscape-specific responses to limiting factors.
These were dependent on the effects of the hydrological network,
anthropogenic features, topographic complexity, and the heterogeneity of
the landcover patch mosaic. Overall, even accounting for specific local
differences, we found general landscape attributes associated with snow
leopard ecological requirements, consisting of a positive association
with uplands and ridges, aggregated low-contrast landscapes, and large
extents of grassy and herbaceous vegetation. As a means to evaluate the
performance of two bias correction methods, we explored their effects on
three datasets showing a range of bias intensities. The performance of
corrections depends on the bias intensity; however, density kernels
offered a reliable correction strategy under all circumstances. This
study reveals the multi-scale response of snow leopards to environmental
attributes and confirms the role of meta-replicated study designs for
the identification of spatially varying limiting factors. Furthermore,
this study makes important contributions to the ongoing discussion about
the best approaches for sampling bias correction.

Abstract: Menzbier's marmot is preyed on by snow leopard, bear, wolf, fox, bearded vulture, golden eagle, black vulture, and raven. A harm caused by the predators to the Kazakhstan population of marmot made up 2,000 3,000 in 2001.

Abstract: Hibiscus section Furcaria is composed of over 400 species. Kenaf (Hibiscus cannabinus) and rosella (Hibiscus sabdariffa) belong to this section. Both species are important fiber crops. The survey reported in this book was undertaken in order to find new sources of genetic diversity collect, save, and distribute germ plasm. The work contains a taxonomic key of section Furcaria in southern Africa, 8 species, a description of the species illustrated by line-drawings, and distribution maps. (Also discussed are; H. mechowii, H. meeusei, H. surattensis, H. acetosella, H. torrei, H. mastersianus, H. hiernianus, H. altissimus, H. diversifolius sub sp. rivularis.)

Esipov A.V. (1985). Measure for snow leopard protection in Uzbekistan.
Abstract: In Uzbekistan, snow leopard (Uncia uncia Schreber, 1776) is met in the mountain ridges of Tien Shan (Karjantau, Ugam, Pskem, Chatkal, and possibly Kurama ridges) and Alay (Turkistan, Zaravshan, Gissar, and Baisuntau ridges). There are about 50 snow leopards there. They are observed to decrease in number for the reasons as follows: extensive use of alpine pastures, tourist activity and poaching. Irbis is under protection in the Chatkal, Zaamin, and Gissar nature reserves and Zaamin people's park. An additional measure to be taken to protect this species is to expand the area of the Chatkal nature reserve, to better fight against poaching activity and advocate snow leopard protection in mass media.

Kaletskiy A.A. (1974). May-“traven”.
Abstract: Diverse flora and fauna and seasonal phenomena in nature are stated in a popular form. Snow leopard is noticed to be a rare species, its population being significantly influenced by catching for zoos: over 400 snow leopards have been caught for this purpose over the last 35 years.

Abstract: This survey was being done (May, 1975 February, 1976) in the new Kyzylsu nature reserve, established in 1975. Before 1975, the anthropogenic pressure was mainly represented by overgrazing and unregulated hunting. Provided are data on bird species (bearded vulture, Himalayan vulture, griffon vulture, golden eagle, and Himalayan snow cock), mammal species (long-tailed marmot, Indian porcupine, brown bear, lynx, snow leopard, and Siberian ibex).

Abstract: It provides a list of mammals of Central Asia (species and sub-species) indicating their main habitats, and undertakes an attempt to zone fauna of Central Asia based on data collected by the world science community concerning distribution of various mammal species over the country. Snow leopard Uncia uncia Schr. was indicated to inhabit the mountains of Central Asia.
