Salim Ali's fruit bat, Latidens salimalii, is a monotypic endangered fruit bat endemic to Western Ghats (WG) with an ambiguous distribution. The distribution range, habitat suitability, and biology of this species are still uncertain. Endemic species inhabiting the high elevation of WG like L. salimalii are threatened due to climatic change and seeks urgent management interventions. Hence, we developed a habitat suitability model for L. salimalii using MaxEnt in the current climate condition and projected their distribution for three Representation Concentration Pathway (RCP 4.5, 6.0, and 8.5) climate scenarios of the 2070 time frame. The results show that 9531 km2of habitat in WG is suitable for L. salimalii at present, while all the future scenarios estimates propose complete loss of highly suitable habitat. The significant factors influencing the distribution of L. salimalii are the precipitation of the driest month, tree density, rain in the coldest quarter, canopy height, and altitude. The study pioneers in predicting the suitable habitat and emphasis the need to develop strategies for the long-term conservation of endangered L. salimalii in WG under global warming scenarios.

濒临灭绝的三叶草栖息地适宜性模型和全球变暖的可能后果

Salim Ali 的果蝠Latidens salimalii是西高止山脉 (WG) 特有的单型濒危果蝠,分布不明确。该物种的分布范围、栖息地适宜性和生物学仍不确定。由于气候变化,栖息在 WG 高海拔地区的地方性物种如L. salimalii受到威胁,并寻求紧急管理干预。因此,我们在当前气候条件下使用 MaxEnt 开发了L. salimalii的栖息地适宜性模型,并预测了它们在 2070 年时间框架内的三种代表性浓度路径(RCP 4.5、6.0 和 8.5)气候情景中的分布。结果表明,WG 9531 km 2的栖息地适宜L. salimalii目前,虽然所有未来情景估计都建议完全丧失高度适宜的栖息地。影响L. salimalii分布的显着因素是最干燥月份的降水量、树木密度、最冷季度的降雨量、冠层高度和海拔高度。该研究率先预测了合适的栖息地,并强调需要制定在全球变暖情景下长期保护 WG 濒临灭绝的L. salimalii的战略。
