Large herbivores possess high dispersal rates and require vast areas to roam due their ecology. This will make them susceptible anthropogenic threats such as vehicle-collisions. Persian onager (Equus hemionus onager), the only representative of Artiodactyla in Iran, is not an exception. onager-vehicle collision can be lethal for themselves but also motorists. Given importance this twofold issue, important step being taken reduce collisions was installation signs that warn motorists probability collisions. We developed a questionnaire (1) assess effectiveness warning from motorists' perspective, (2) identify most factors affecting motorist beliefs signs. solicited responses our on road with onager-vehicle-collision rate Southern Iran (Hassan Abad-Meshkan Road).

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

Identifying spatial gaps in conservation networks requires information on species-environment relationships, and prioritization of habitats corridors. We combined multi-extent niche modeling, landscape connectivity, gap analysis to investigate scale-dependent environmental identify core corridors for a little-known carnivore Iran, the striped hyaena (Hyaena hyaena). This species is threatened Iran by road vehicle collisions direct killing. Therefore, understanding factors that affect its habitat suitability, pattern distribution, connectivity among them are prerequisite steps delineate strategies aiming at human-striped co-existence. The results showed highest predictive power extent was obtained sizes 4 2 km, respectively. Also, revealed number changed with increasing dispersal distance, approximately 21% found support 15-17% overlapped areas. Given body size species, mobility, lack significant specialization we conclude this would be more strongly influenced changes amount rather than configuration.

Humans are responsible for over a quarter of all wildlife mortality events across the globe. The pressure this puts on populations contributes to decline many at-risk species. To minimize human-caused and reverse population declines in species world, we first need know where these happening or likely occur since managers public agencies often have limited resources devote problem. As such, our objective was develop modeling approach delineate hotspots regions with data. We used internet search engines national media collect data brown bear (Ursus arctos) Iran from 2004 2019. then developed spatially-explicit Maximum Entropy (MaxEnt) model using anthropogenic environmental variables predict probability mortality. were able 7000 km2 as hotspots, along geographical locations those hotspots.

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.

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

Structural modeling (SCM) attempts to quantify the degree which physical features facilitate or impede movement of individuals and has been widely used identify corridors, but its accuracy rarely validated against empirical data. Objectives We evaluated SCM’s ability suitable habitat corridors onagers ( Equus hemionus onager ) through a comparison with functional (i.e., actual individuals) using satellite tracking Methods MaxEnt predict three SCM approaches: circuit theory, factorial least cost path, landscape approaches corridors. The performance was independently collected GPS telemetry Results Onagers selected water sources dense vegetation while avoiding areas grazed intensely by livestock. SCMs identified similar were interrupted roads, affecting major high-flow overlapped about 21%. Conclusion Movement derived from did not align locations intensity model. This finding suggests that might have tendency overestimate resistance low suitability. Therefore, may adequately capture individual decisions selection movement.
