Carnivores play key roles in maintaining ecosystem structure and function as well ecological processes. Understanding how sympatric species coexist natural ecosystems is a central research topic community ecology biodiversity conservation. In this study, we explored intra- interspecific niche partitioning along spatial, temporal, dietary between apex carnivores (wolf Canis lupus , snow leopard Panthera uncia Eurasian lynx Lynx ) mesocarnivores (Pallas’s cat Otocolobus manul red fox Vulpes vulpes Tibetan ferrilata Qilian Mountain National Park, China using camera trapping data DNA metabarcoding sequencing data. Our study showed that carnivore had more overlap temporally (coefficients of ranging from 0.661 to 0.900) or trophically (Pianka’s index 0.458 0.892), mesocarnivore high with each other 0.945 0.997), temporal 0.497 0.855).

The snow leopard (Panthera uncia) lives in alpine ecosystems Central Asia, where it could face intensive climate change and is thus a major conservation concern. We compiled dataset of 406 GPS-located occurrences based on field surveys, literature, the GBIF database. used Random Forest to build different species distribution models with maximum 27 explanatory variables, including climatic, topographical, human impact predict potential for make projections. estimated range shifts under two global representative concentration pathways 2050 2070. found center may move northwest by about 200 km upward elevation 100 m Unlike previous studies leopard, we highlighted that rather than northward are main changing climate, since landform their habitat allows an shift, whereas mountains valleys would block movement. Conservation should therefore prioritize protecting its current over making movement corridors.

The rapidly changing environments resulting from anthropogenic activities and climate change present challenges to biodiversity protection efforts. China, in its pursuit of sustainable economic growth urban development, grapple with the increasing challenge designating national protected areas for conservation a proactive ecologically effective manner. In this study, we collected occurrence data snow leopard (Panthera uncia), species high concern, A'nyamaqen Bortala China's Qinghai Xinjiang provinces, respectively. Using random forest analysis, conducted multi-scale habitat selection modeling quantify compared habitats between two sites. Three models were created utilizing either Qinghai, Xinjiang, or combination both sites, enabling investigation nonstationarity limiting factors different landscapes. Although there minor differences variable ranking optimal scales among models, they consistently indicated strong negative relationship proximity roads suitability at broader scales. These findings provide insights into spatially varying leading divergent realized niches parts their Chinese range. Understanding these context-dependent preferences is vital assessing impact infrastructure development on populations. Overall, study underscores importance understanding face environments. contribute ongoing efforts emphasize need adaptive approaches that address posed by environmental transformations.
