“…Our results show that the southeastern parts of the region contain more suitable habitats for jackals and most road mortalities were recorded in the south parts of the study area. This could be due to the greater traffic volume on the south highways and to the high concentration of villages and rural areas in the south parts resulting in increased food resource availability such as dumpsites (Mohammadi et al, 2018;Tourani, Moqanaki, & Kiabi, 2012). The jackal is known as an elusive species that is timid around humans thus the species is primarily nocturnal and under high risk of vehicle collisions at night (Tóth, Krecsák, Sz[?…”

Central Iran supports a diversity of carnivores, most of which are threatened by habitat loss and fragmentation. Carnivore conservation requires the identification and preservation of core habitats and ensuring connectivity between them. In the present study, we applied species distribution modeling to predict habitat suitability and used connectivity modeling to predict linkage (resistant kernel and factorial least-cost path analyses) for grey wolf and golden jackal in central Iran. For grey wolf, elevation, topographic roughness and distance from agriculture lands were the strongest predictors; however, for golden jackal, distance from agriculture lands, human settlements and topographic roughness were the most influential variables in predicting the occurrence of this species. Our results also indicated a high potential for large parts of the landscape to support the occurrence of these two canid species. The largest and the most crucial core habitats and corridor paths for the conservation of both species are located in the southern part of the study landscape. We found a small overlap between golden jackal corridor paths and core habitats with protected areas, which has important implications for conservation and future viability of the golden jackal populations. Some sections of core areas are bisected by roads, where most vehicle collisions with grey wolf and golden jackal occurred. We propose that effective conservation of both species would require integrated landscape-level management to reduce mortality risk, as well as protection of core areas and corridors and development of mitigation strategies to reduce vehicle collisions.

“…Hyaena hyaena (Linnaeus, 1758) is the only extant species of hyaenidae in Iran (Firouz, 2005). The Striped hyena, a "near-threatened" species in the IUCN Red List (AbiSaid and Dloniak, 2015), is also considered vulnerable in this country, suffering from the loss of its natural habitats, less availability of carcasses, persecution by local human populations, and vehicle collision (Tourani et al, 2012). Studies of habitat evaluation of the species show that open landscapes dominated by Artemisia steppes, with the presence of limestone outcrops providing rock shelters, are the ideal environmental conditions for denning activities (Rezaei et al, 2017).…”

“…Striped hyenas can be considered as omnivorous scavengers because they also feed on fruits, vegetables, and occasionally human refuse (Rieger, 1979;Wagner, 2006). The availability of these plant food resources, as well as the livestock carcasses around human settlements, is increasingly drawing striped hyenas to peri-urban areas, habitations, and landfills (Monchot and Mashkour, 2010;Shamoon and Shapira, 2019) which is not necessarily beneficial to the survival of this threatened species (Tourani et al, 2012).…”

The striped hyena is the largest living omnivorous scavenger in SW Asia. It generally lives in semi-arid desert steppe regions, often denning in small caves, rock shelters, and burrows close to human settlements. Bone fragments of wild and domestic animals and desiccated scats are frequently found in the hyena dens. In this study, eight striped hyena desiccated scats were subjected to pollen analysis. All scats were rich in pollen and the exine was well-preserved with no visible sign of corrosion. Pollen spectra revealed interesting information on the regional and local vegetation, as well as the foraging behavior and diet of the animal. They reflected an array of different landscapes ranging from natural/semi-natural xerophytic desert steppes, agricultural fields, and grazing pastures. Some scats contained certain pollen taxa very rarely observed in wetland sediments, indicating the high potential of hyena "copropalynology"in providing detailed information on the past floristic composition of the landscape. When comparing with archeobotanical data from the area, the hyena scat assemblages show that the general physiognomy of the landscape has remained almost unchanged since the 6th millennium B.C., with only minor changes in the composition or density of the woody components of the desert steppe. As most of the Holocene fossil coprolites in archeological and paleontological sites of SW Asia would have been left by striped hyena, the study of the modern analogs of such accumulations in extant hyena dens is helpful to correctly interpret the fossil faunal assemblages to reconstruct the paleolandscapes, land-use change, and animal paleoethology.

“…Large carnivores live at low densities and typically require large and well connected habitats [ 36 ]. Striped hyaenas ( Hyaena hyaena ) are one of the least studied large carnivores in Iran and there is limited data available on their habitat needs and spatial distribution [ 37 ]. The striped hyaena population in Iran is threatened by road vehicle collisions and direct killing (poisoning) due to perceived risk posed to pastoralists and their use in traditional medicine [ 37 , 38 ].…”

Combining multiscale niche modeling, landscape connectivity, and gap analysis to prioritize habitats for conservation of striped hyaena (Hyaena hyaena)

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