Climate change is projected to create alterations in species distributions over the planet. The common leopard (Panthera pardus) serves an important ecological function as a member of big carnivore guild, but little known about how climate may affect their distribution. In this study, we use MaxEnt simulate geographic by illustrating potential present and future ranges utilizing presence records alongside topographic bioclimatic variables based on two shared socioeconomic pathways (SSP2-4.5 SSP5-8.5) scenarios. goals study was look into possible distribution leopards due change, well explore implications for conservation conflict with humans. At present, 4% Nepal found be highly suitable leopards, 43% suitable, 19% marginally 34% unsuitable. A large portion climatically habitat confined non-protected areas, majority encompassed forest land, followed agricultural areas. Elevation, mean temperature driest quarter, annual precipitation, precipitation seasonality were influencing suitability leopard. significant increase observed high mountain region, indicating shift upper elevation areas effects change. We recommend timely management these habitats expand range vulnerable species. same time, combination expanding new poor practices could escalate human-leopard conflict. Therefore, further impact prey proper techniques should prioritized mitigate conflicts.

Abstract Climate change could amplify the extinction risk of endemic species, and is even greater for species occupying high elevations mountain ranges. In this study, we assessed climatically suitable habitat only Nepalese bird spiny babbler ( Turdoides nipalensis ), predicted extent future (2050 2070) under two climate scenarios (SSP2‐4.5 SSP5‐8.5). We used georeferenced occurrence points alongside ecologically meaningful climatic topographic variables to develop an ensemble model using different distribution modeling algorithms in BIOMOD2. identified 22,488.83 km 2 (15%) Nepal's total land area as where nonprotected regions incorporated largest (88%), with a majority within central Mid‐Hill region. Under SSP2‐4.5 scenario, 21.58% 34.08% current range are projected be lost by 2050 2070, respectively. Whereas SSP5‐8.5 our projections suggest that 40.45% 52.18% will Habitat suitability increased rise warmest quarter precipitation (above 1000 mm), coldest between 50 100 mm, temperature 20 30°C. Given results, it crucial review conservation policy areas formulate babbler‐specific action plan special focus on protecting their primary human‐dominated landscapes areas.

Abstract The striped hyena ( Hyaena hyaena ) is considered “Near Threatened” globally and “Vulnerable” in the Middle East. In Israel, species has experienced extreme population fluctuations owing to poisoning campaigns during British Mandate (1918–1948) which were also further exacerbated by Israeli authorities mid-twentieth century. We collated data from archives of Israel Nature Parks Authority for past 47 years elucidate temporal geographic trends this species. During period we found a 68% increase estimated density at present 2.1 individuals/100km 2 . This significantly higher than all previous estimates Israel. It appears that major factors contributing their phenomenal number are prey availability because intensification human development, preying on Bedouin livestock, extinction leopard Panthera pardus nimr ), hunting wild boars Sus scorfa other agricultural pests some parts country. Reasons should be sought increasing people's awareness as well advanced technological capabilities have allowed an improved observation reporting system. Future studies need understand effects large concentrations hyenas spatial distribution activity sympatric wildlife ensure continued persistence guilds nature.

Abstract To assess threats to the population of native mammals and their survival, we performed a retrospective study utilizing rescue rehabilitation database from Nepal. Based on total number 1013 cases involving six taxonomic families admitted over five years, outcome (mortality survivability) differed significantly among taxa ( χ 2 [df = 5, N 1013] 65.08, p < .001). The mortality rate was highest in Felidae (74%), followed by Herpestidae (69%), Viverridae (62%), Bovidae (50%), Cervidae Cercopithecidae (38%). also causes admission 9, 241.48, prevalence gunshot poisoning, collision with vehicle, diseases/infection, entanglement/trapped, injured dogs/cats, abandoned/orphaned, humans, unknown causes, domestic/captivity issues. Multiple logistic regression analysis showed significant influence family, age group, cause likelihood rescued mammals. odds ratio higher for carnivore taxa, juveniles were more likely succumb death than adults.

Over the last few years, intensifying human impact and deterioration of natural habitats have severely restricted global distribution large herbivores. Rucervus duvaucelii, commonly recognized as swamp deer, is a habitat-specialist endemic herbivore Indian Subcontinent. It classified vulnerable by IUCN listed in CITES Appendix I due to steep decline its population, which primarily anthropogenic causes. In Nepal, remaining population this species confined limited pocket areas within western Terai Arc Landscape. We explored potential habitat for deer across landscape using modelling through MaxEnt algorithm 173 field-verified presence points alongside six anthropogenic, four topographic, vegetation-related variables. Our study found that out total area (9207 km2), only 6% (590 km2) was suitable deer. Approximately 45% incorporated protected areas, with Shuklaphanta National Park harboring largest patch. The suitability discovered be positively associated low-elevation near water sources, far from settlements, implying need conserve sources minimize extension pressure their long-term conservation. Additionally, we suggest implications deer-centric conservation strategy, an emphasis on increasing connectivity corridors landscape-level trans-boundary initiatives between Nepal India. Moreover, considering herbivores' high vulnerability extinction, similar researche incorporating factors utmost importance produce vital information conserving other regionally globally endemic, habitat-specialized

Pakistan once had a thriving and diverse fauna. However, there hasbeen significant decline in the wildlife population since late 1800s. The primary factors contributing to this include humanencroachment, conflict with natives habitat damage. Technological development climatic change have also contributed loss of wildlife. Despite extinctionbeing natural process, pace at which it is happening currently unusual. ultimate objective conservation guarantee survival thesespecies, are essential for sustaining stability our environment. To fight these extinction pressures, practices policies been implemented, including creation protected areas plants In current study, main focus has on critically endangered mammal species Pakistan, their loss, necessary measures already being implemented nationally as well globally.
