Owing to the changing climatic scenario globally, and human overexploitation, the risk of extinction of Himalayan endangered species has increased many folds. Taxus contorta, an endangered gymnosperm has reached a decisive state in the Western Himalayas, thus, demands immediate attention to rescue it. This study aims to elucidate population and landscape genetics of T. contorta to plan a successful conservation strategy. We used SSR genotyping to identify genetic diversity hotspots, and ecological niche modeling to reveal climatic hotspots of T. contorta in the Indian Western Himalayas. We observed a substantial genetic diversity, and a negligible level of inbreeding among T. contorta populations. A genetic bottleneck was observed in several populations. We propose that changing climate can cause a failure of an entire conservation management plan if the shift produces a degraded environment in the future, at the sites of conservation. Further, the conservation management is futile if it fails to enhance or conserve the genetic diversity. We propound that use of germplasm from genetic diversity hotspots for propagation in climatic hotspots, and prioritization of these hotspot patches for conservation would ensure greater genetic variability under a safe environment. This integrative approach of translating molecular and climatic data into conservation planning would save our efforts, time, and capital investment, and ensure greater success in managing the revival of T. contorta in the Western Himalayas.

由于全球气候变化和人类过度开采，喜马拉雅濒危物种灭绝的风险增加了许多倍。濒危的裸子植物红豆杉已经在西喜马拉雅山达到了决定性的状态，因此，需要立即予以关注以对其进行营救。本研究旨在阐发的人口和景观遗传学T.扭叶松策划一个成功的保护策略。我们使用SSR基因分型来识别遗传多样性热点，并使用生态位建模来揭示印度西部喜马拉雅山中锥角锥。的气候热点。我们观察到大量遗传多样性，以及在捻转锥虫中近交的水平可忽略不计人口。在几个人群中发现了遗传瓶颈。我们建议，如果这种变化在将来会导致保护地点的环境恶化，那么气候变化可能会导致整个保护管理计划失败。此外，如果保护管理无法增强或保护遗传多样性，那将是徒劳的。我们建议使用遗传多样性热点的种质在气候热点中繁殖，并优先考虑这些热点斑块进行保护，以确保在安全环境下更大的遗传变异性。这种将分子和气候数据转化为保护计划的综合方法将节省我们的工作，时间和资金投入，并确保在控制锥虫的复兴方面取得更大的成功。 在西喜马拉雅山。
