Salim Ali's fruit bat, 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 are threatened due to climatic change and seeks urgent management interventions. Hence, we developed a habitat suitability model for 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 kmof habitat in WG is suitable for at present, while all the future scenarios estimates propose complete loss of highly suitable habitat. The significant factors influencing the distribution of 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 in WG under global warming scenarios.
萨利姆·阿里果蝠是西高止山脉特有的单型濒危果蝠,其分布情况不明。该物种的分布范围、栖息地适宜性和生物学特性仍不确定。像这样栖息在西高止山脉高海拔地区的特有物种因气候变化而受到威胁,急需管理干预措施。因此,我们在当前气候条件下使用最大熵模型(MaxEnt)为其开发了栖息地适宜性模型,并预测了它们在2070年时间框架内三种代表性浓度路径(RCP 4.5、6.0和8.5)气候情景下的分布。结果表明,目前西高止山脉9531平方千米的栖息地适合该物种生存,而所有未来情景估计都表明高度适宜的栖息地将完全丧失。影响该物种分布的重要因素是最干燥月份的降水量、树木密度、最寒冷季度的降雨量、树冠高度和海拔。这项研究率先预测了适宜栖息地,并强调需要制定战略,以便在全球变暖情景下对西高止山脉的濒危物种进行长期保护。
