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.

We used Maxent to model the distribution of the Nilgiri marten (Martes gwatkinsii), a cryptic semi-arboreal mammal, with climate, forest, and human disturbance as covariates. We modelled the species niche, which identified suitable habitat across a variety of land uses and protection regimes. The findings point to a species niche defined by isolated, cold, and wet areas along the Western Ghats’ montane grasslands (shola) and adjoining wet forests. A sizable portion (62 %) of the total 8922 km2 niche area is multi-use, including tea, coffee, and timber plantations. Our findings emphasise the importance of conservation in non-protected areas adjacent to reserves in order to sustain this endemic species.
