In recent years, global warming has become a major driver of biodiversity loss, significantly impacting various vertebrate species, including mammals. Consequently, numerous smaller species face extinction risks due to anthropogenic factors as well inadequate assessments and conservation planning. Thus, this study focuses on two recently described endemic giant flying squirrel under the Petaurista genus—Petaurista mishmiensis mechukaensis—found in Arunachal Pradesh, India. Using an ensemble distribution model (SDM), research delineates suitable habitats for these lesser-known evaluates effects climate change habitat fragmentation areas. This analysis aims inform comprehensive management plan their conservation. The identified patches extending beyond current IUCN-designated ranges Pradesh. Under present conditions, P. largest predicted area (9213 sq. km), followed by mechukaensis (6754 km). However, future projections reveal alarming losses ranging from 13.45% 55.86% across area. also highlights severe throughout state viable are drastically reduced size, resulting many being completely lost remaining areas closer together. experiences significant disintegration, smaller, more dispersed within Hence, address challenges, recommends several actions such genetic confirm evolutionary relationships, evaluations corridor connectivity, field studies. Furthermore, establishing joint forest committees involving local communities, personnel, defense forces, naturalists, scientists encouraged. Ultimately, provides critical insights guiding studies Pradesh’s vast landscapes supports development detailed plans protect squirrels.

Global warming and anthropogenic threats are significant drivers of biodiversity loss, particularly impacting smaller mammalian species. Hence, this study assessed two overlooked giant flying squirrel species, Petaurista magnificus nobilis, distributed across the transboundary regions Eastern Himalayas Indo-Burma hotspots. Utilizing a maximum entropy (MaxEnt) species distribution model, delineated suitable habitats within IUCN-defined extent both based on modeling approaches: habitat–climate model (HCM) climate-only (COM). The models identified habitat coverage only 3.92% 3.75% (COM) for P. 14.17% 10.04% nobilis. However, as HCM integrates environmental variables, providing more holistic assessment, it revealed limited biological corridor connectivity Furthermore, future projections indicate loss up to 81.90% 89.88% nobilis due climate change, alongside severe fragmentation, leading disappearance viable patches. These remaining patches expected shrink become increasingly isolated in change. centroid shift analyses predict northwestward westward under different scenarios. address these conservation challenges, underscores necessity extensive field surveys, genetic assessments, evaluations, establishment frameworks formulate an evidence-based management strategy
