The main cause of the global threat to large carnivore populations living in high-altitude areas is human pressure. Himalayan brown bear ( Ursus arctos isabellinus , hereafter bear) listed as a critically endangered species, and it dominates higher altitudes North Western landscapes. Here, we used species distribution modelling landscape connectivity find bears’ suitable habitats corridors Deosai National Park (DNP) surrounding areas. Species models detected bear’s habitat 1,125 km 2 which ca. 73% was covered by DNP. most crucial predictors determining were elevation—particularly if between 3,500 4,500 meters above sea level—as well distance from rivers, cattle, DNP borders. We discovered robust among presence points core study area, particularly within boundaries, using electrical circuit theory models. Landscape values indeed low some outside close confines. Based on our findings, imperative protect that allow bears migrate patches, beyond park’s improve conservation.

Abstract Conservation of large carnivores requires preservation extensive core habitats and linkages among them. The goal this study was to identify corridors by predicting habitat suitability (an ensemble approach), calculating resistant kernel factorial least-cost path modeling for a relatively unknown carnivore, the striped hyaena in Khuzestan area southwestern Iran. We used procedure spatial randomization test evaluate coincidence road crossing with predicted corridors. results revealed that elevation, distance conservation areas, categorical climate grasslands density were most influential variables occurrence area. In estimated dispersal 70 km, four identified. largest located northeast highest connectivity contribution. Only about 12% 1.5% protected respectively. Predicted corridors, crossed roads represented high risk hyaenas. Adaptive management plan throughout landscape (conservation reducing species mortality on roads) must be considered wildlife managers

Forest degradation is a serious environmental issue that has significant implications for ecological stability, biodiversity, and human well-being. Identifying the extent severity of forest crucial effective management conservation ecosystems. The objective this study was to assess vulnerability in Dadabad region using spatial analysis landscape metrics. land cover map area divided into 13 sub-basins quantify metrics, activities, level, were calculated each sub-basin. Each sub-basin evaluated as single determine degradation, zoning performed based on coefficients. found 2 4 had highest levels while 3, 7, 8, 11, 12 least degraded. Over half region, 37.8% protection 32.25% rehabilitation, recommended planning. research highlights importance metrics assist managers planners protecting conserving natural areas.

Connectivity among conservation areas helps to alleviate the negative impacts of habitat fragmentation. Mouflon (Ovis gmelini) as a near threatened species has an unclear connectivity status in west Iran. This study was carried out on mouflon with aim modeling suitability and core habitats An ensemble three machine-learning models factorial least-cost path were used for identifying corridors between them, respectively. Our results revealed that grassland density, elevation, slope distance roads most influential variables predicting occurrence area. Five identified area, about 90% which covered by areas. The north area is highest priority conservation. Conservation northern western parts had best mouflon. To prevent poaching, protection should be considered. In addition, predicted crossed roads, could investigated wildlife managers.

Distribution range shift is inevitable for many species as climate change continues to shape and alter their habitat. Predicting where these shifts occur can help us know what anticipate thus design better programs strategies management. Due projected extreme in arid semi-arid ecosystems, we hypothesized that adapted systems would experience considerable spatial shifts. To test our hypothesis, modelled current future habitats under different scenarios three iconic carnivores (grey wolf, golden jackal, striped hyaena) central of Iran calculated overlaps. Our models predict although each responds differently environmental changes, are heavily influenced by climatic variables, water resources, roads. also suggest the high-quality grey wolves hyaenas will probably expand, while jackals, it decrease. Significant overlap highly suitable habitat exist among species, particularly between jackal hyaena. The overlapped areas all cover 9% 10% whole region at present future. Because decrease rainfall future, may face competition due change. findings crucial establishing conservation conserve carnivore

Protected areas (PAs) are crucial for conserving species and ecosystems but still susceptible to deforestation degradation from human natural causes. The Uaymil Area in Quintana Roo, Mexico, is a key ecological corridor facing risks due its location. Due this the objective of study was evaluate conservation status analyze spatial temporal changes within vegetation type protected area flora fauna “Uaymil” using Ecosystem Quality Index (EQI). MODIS Terra satellite data Leaf (LAI), Gross Primary Productivity (GPP), Fractional Vegetation Cover (FVC) were used calculate annual EQI over 23 years. results showed strong integration LAI, GPP, FVC into EQI, improving model's ability capture ecosystem quality changes. Significant shifts occurred 2005, 2011, 2015, 2023, indicating both recovery. Lower values found mangrove marsh areas, while forests had higher indicators. Overall, maintains high cover quality, status.

Knowledge of landscape fragmentation is known to be important in ecological integrity, hydrological processes, urban planning, sustainable land management, and policymaking. Recent anecdotal studies reveal a need for analytical quantification at different levels. Therefore, the present study was conducted KoozehTopraghi Watershed, Ardabil Province, Iran, where covers by uses/covers, (a) explore spatial pattern metrics comprehensively scales, (b) distinguish hot spots, (c) investigate clustering metrics. The behaviors 7, 10, 13 concerning three levels patch, class, across 36 sub-watersheds were explored using principal component analysis (PCA) expert elicitation.
