Invasive species are considered as one of the major threats to biodiversity and represent a challenge in conservation natural ecosystems, preventing damage agricultural production, human health risks. Environmental Niche Modelling has emerged powerful tool predict patterns range expansion non-native direct effective strategies for managing biological invasions. The raccoon, Procyon lotor, is wild mesocarnivore presenting high adaptability showing successful introduced populations worldwide. Here, we modelled current future climatically favourable areas raccoon using two protocols, based on data sets filtrated geographic environmental spaces. Projections from these models show extensive geographical covering regions temperate biomes. Moreover, predictions 2050 reveals new north regions. However, results modeling approaches differ extent predicted Protocols geographically filtered present more conservative forecasts, while protocol filtration presents forecasts across greater areas. Given characteristics ecological requirements generalist carnivore such latter appears relevant should be privileged development plans ecosystems.

Pakistan’s total estimated snow leopard habitat is about 80,000 km 2 of which half considered prime habitat. However, this preliminary demarcation was not always in close agreement with the actual distribution—the discrepancy may be huge at local and regional level. Recent technological developments like camera trapping molecular genetics allow for collecting reliable presence records that could used to construct realistic species distribution based on empirical data advanced mathematical approaches MaxEnt. The current study followed approach an accurate Pakistan. Moreover, movement corridors, among different landscapes, were also identified through circuit theory. probability suitability, generated from 98 points 11 environmental variables, scored leopard’s assumed range Pakistan, 0 0.97. A large portion known represented low-quality habitat, including areas lower Chitral, Swat, Astore, Kashmir. Conversely, Khunjerab, Misgar, Chapursan, Qurumber, Broghil, Central Karakoram high-quality habitats. Variables higher contributions MaxEnt model precipitation during driest month (34%), annual mean temperature (19.5%), diurnal (9.8%), (9.4%), river density (9.2). validated receiver operating characteristic (ROC) plots defined thresholds. average test AUC Maxent replicate runs 0.933 while value by ROC curve calculated 0.15 threshold 1.00. These validation tests suggested a good fit strong predictive power. connectivity analysis revealed population Hindukush landscape appears more connected Afghanistan as compared other populations Similarly, Pamir-Karakoram better China Tajikistan, Himalayan India. Based our findings we propose three landscapes under Global Snow Leopard Ecosystem Protection Program (GSLEP) agenda priority areas, safeguard future Pakistan region. fall within mountain ranges Himalaya, Hindu Kush Karakoram-Pamir, respectively.

Range shifts range contractions in will dramatically affect distribution animals relying on them for food shelter. The negative impacts change forested landscapes northern highlands Pakistan (NHP) could composition distribution. Asiatic black bear ( Ursus thibetanus ), a forest‐dwelling species, primarily depends plants foraging, is assumed be affected NHP.
