“…e results showed that Tibetan antelopes prefer to cross highways in a location where the distance between the highway and the railway is large, the surrounding terrain is relatively flat and open, and there are good visibility conditions. e Qinghai-Tibet Railway was built parallel to the Qinghai-Tibet Highway, and these two transportation routes have overlapping barrier effects on the movement of Tibetan antelopes [28]. is suggests that the design of animal corridors and overlapping barrier effects should be more carefully considered when new highways are built in highaltitude areas.…”

“…ese two transportation routes have overlapping barrier effects on the migration of antelopes, and the magnitude of the barrier effect increases as the distance between the two routes decreases [28]. Further analysis showed that the distance between the highway at K2904 and the railway is less than 300 m. ere is no effective safety gap between the two routes, which is the reason that Tibetan antelopes did not cross the highway at this location.…”

Highways that cross natural reserves are an intrusion with a nonnegligible negative impact on the behavior of wild animals and have numerous and diverse ecological impacts on wildlife near road areas. Field experiments were carried out to collect traffic flow data on the Qinghai-Tibet Highway on the Qinghai-Tibet Plateau, China, and the behavior of the Tibetan antelope crossing the highway was observed. The relationships between the percentage of antelopes successfully crossing the highway and the different traffic flows were analyzed. The results demonstrate that the traffic volume is the main factor affecting the success rate of Tibetan antelopes when crossing the highway, displaying a nonlinear negative correlation. Furthermore, the behavioral responses of the Tibetan antelopes within 500 m of the Qinghai-Tibet Highway before and after different parking behaviors were observed and the proportions of the different behaviors exhibited by the Tibetan antelopes affected by different driver parking behaviors were analyzed. Parking behaviors were found to have the most significant effect on Tibetan antelope behavior within 400 m of the highway, where parking with somebody getting out having the most prominent impact. The results of this study can guide engineering measures to protect wildlife in the plateau region.

“…The important wild herbivores in the study area include Blue sheep ( Pseudois nayaur ) and Siberian ibex ( Capra sibirica ), while the notable carnivores include Snow leopards, Wolves, Brown bears ( Ursus arctos isabellinus ), Lynx ( Felis lynx ), and Tibetan red fox ( Vulpes vulpes montana ). Other mammals including Golden marmots ( Marmota caudata aurea ) and Cape hares ( Lepus capensis ) also inhabit the study region (Baig et al, 2022; Knudsen, 1999; Shafiq & Ali, 1998; Wang et al, 2012).…”

The livestock depredation by large carnivores is a main cause for increasing human-wildlife conflicts (HWCs) and is one of the prime challenges for carnivore's conservation and a major economic concern to livestockdependent communities around wildlife habitats. Thus, understanding the patterns and trends of livestock depredation may contribute to better understanding of the mechanisms underlying HWCs and to mitigating HWCs. HWCs characterized by livestock depredation by large carnivores are prevalent in northern Pakistan, but the underlying mechanisms are poorly investigated. This study was conducted in 2018 in the Khunjerab Valley and Shimshal Valley of the Pamir region to evaluate the spatial and seasonal variation and impact of livestock depredation by carnivores. Data were collected on livestock depredation and its associated economic impact through semi-structured interviews of randomly selected households in the two valleys. The livestock in Shimshal Valley was more susceptible to large carnivores' depredation (233 heads per year) than in Khunjerab Valley (125 heads per year). This spatial variation in livestock depredation was reflective of the difference in the socio-economic conditions and physical locations between the two valleys. More livestock depredation took place in winter in Khunjerab Valley, while more livestock depredation occurred in summer in Shimshal Valley, mainly because of different grazing systems in the two valleys. The total economic loss incurred due to large carnivores'

“…In this case, the sensor needs to be chosen specifically for its sensitivity to differences in solar energy reflectance and/or thermal radiation between the animal and the environment. Another good application of this type of imaging is for monitoring the nocturnal activity of mammals 34 . 35 used a UAV to conduct a population census of large wild herbivores in Maduo County on the Tibetan Plateau.…”

This publication is a review of the application of remote sensing methods for wildlife population monitoring in zoology. Remote sensing methods are divided into four categories. The first category of methods examines the application of camera traps, the second is about application of unmanned aerial vehicles (UAV), the third category examines the application of satellite images, and the fourth category is summarizing studies focused on GPS tracking. The use of camera traps for monitoring wild life populations proved to be a very applicable and reliable field method for collecting appropriate data on large mammals. Monitoring animal populations through satellites is a method that allows many biogeographic hypotheses related to migration and species distribution. Data obtained from satellite platforms is used as an indirect method in zoology to assess the habitats and food base of animals, as well as to create models of species distribution. Images obtained from UAVs are a new method for conducting studies of wildlife populations, showing greater accuracy and efficiency than conventional methods. GPS tracking is an extremely suitable method used to identify breeding and wintering sites, migration routes, and resting places of many species of migratory birds and mammals. The literature review shows that monitoring animal populations through remote sensing methods are cost and time effective methods that can be successfully performed without exposing researchers to risk. It allows monitoring of difficult-to-access places and large territories as well as to create models of species distribution.
