快速变化的景观中的野生动物管理需要通过交叉网络进行关键规划，并了解通常受人类活动影响的景观特征。本研究展示了印度干城章嘉峰景观（KL）小熊猫（Ailurus fulgens）种群遗传变异和当代基因流与景观连通性的精细空间模式。研究发现，印度吉隆坡适宜小熊猫生存的面积约为1,309.54平方公里，其中62.21%的面积属于保护区网络。我们从 9 个微卫星位点收集的 234 份粪便中鉴定出了 24 个独特的个体。空间显式和非显式贝叶斯聚类算法显然可以展示种群结构并支持小熊猫种群存在于元种群框架中。与栖息地适宜性和景观连通性模型相一致，基因流结果支持小熊猫通过新月弧连接吉隆坡和印度的当代不对称运动。我们展示了吉隆坡-印度走廊的结构-运营连通性，这在过去促进了小熊猫的迁徙。我们还寻求与尼泊尔、不丹和中国合作，协助制定跨境景观中小熊猫长期保护和管理的全面监测计划。
Wildlife management in rapid changing landscapes requires critical planning through cross cutting networks, and understanding of landscape features, often affected by the anthropogenic activities. The present study demonstrates fine-scale spatial patterns of genetic variation and contemporary gene flow of red panda (Ailurus fulgens) populations with respect to landscape connectivity in Kangchenjunga Landscape (KL), India. The study found about 1,309.54 km2 area suitable for red panda in KL—India, of which 62.21% area fell under the Protected Area network. We identified 24 unique individuals from 234 feces collected at nine microsatellite loci. The spatially explicit and non-explicit Bayesian clustering algorithms evident to exhibit population structuring and supported red panda populations to exist in meta-population frame work. In concurrence to the habitat suitability and landscape connectivity models, gene flow results supported a contemporary asymmetric movement of red panda by connecting KL—India in a crescent arc. We demonstrate the structural-operational connectivity of corridors in KL—India that facilitated red panda movement in the past. We also seek for cooperation in Nepal, Bhutan and China to aid in preparing for a comprehensive monitoring plan for the long-term conservation and management of red panda in trans-boundary landscapes.
