“…Although considered a habitat generalist, several studies have highlighted the strong dependence of the European badger on forests (Huck et al, 2008;Fabrizio et al, 2019), making it highly vulnerable to forest loss and habitat fragmentation. Also, striped hyaenas in Iran are constantly threatened by road vehicle collisions (Tourani et al, 2014;Mohammadi et al, 2018), habitat destruction and land modification (Dadashi-Jourdehi et al, 2020). Road construction and habitat fragmentation coupled with water scarcity and the aridity of landscapes further reduce the suitable habitats for certain wildlife species in Iran, especially the wild goat.…”

Rapid expansion of roads is among the strongest drivers of the loss and degradation of natural habitats. The goal of the present study is to quantify landscape fragmentation and degradation before and after the construction of the Isfahan-Shiraz highway in southern Iran. To this end, the ecological impacts of the highway on forests, rangelands, and protected areas were evaluated. Impacts of the construction of the highway were studied within a 1,000-m buffer around the road, which was then overlaid on maps of forests, rangelands, and protected areas. Class area, number of patches, largest patch index, edge density, landscape shape index, mean patch size, and patch cohesion index were used to gauge changes in the spatial configuration of the landscape; the ecological impacts of the highway were quantified using effective mesh size (MESH), division index, and splitting index. The results indicated that after the construction of the highway, 6,406.9 ha of forest habitat, 16,647.1 ha of rangeland habitat, and 912 of the Tang-e Bostanak Protected Area will be lost. The effective MESH metric showed that after the construction of the highway, the area of forest, rangeland habitats and protected area will decrease by 20,537, 49,149, and 71,822 ha, respectively. Our findings revealed drastic habitat loss and landscape fragmentation associated with construction of the highway, serving as references for conservation planning and development.

“…The striped hyaena occurs in Asia from the Indian subcontinent to the Levant (including 20 countries) and most parts of Africa except the southern part (including 18 countries) 27 , 28 . According to the IUCN Red List, the striped hyaena has been categorized as a near threatened species (NT), because of persecution (mainly poisoning the carrions) and decreasing domestic and natural carrions 29 .…”

“…Striped hyaenas are one of the least studied large carnivores in Iran and there is limited data available on their habitat needs and spatial distribution. In Iran, the striped hyaena has a widespread distribution; however, its population has decreased severely 27 . The main causes are habitat loss and anthropogenic activities such as conversion of the natural grasslands to agricultural lands, poaching, poisoning the carrions, using organs for medicine and superstitious beliefs, and road collisions 27 , 34 , 35 .…”

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

“…In some cases, it appears wildlife and domestic animals share strains, and in other cases the strains found in wildlife and dogs are quite different. 4,9 In 2020, Dadashi-Jourdehi et al 25 reported that the most suitable habitats for striped hyenas in Iran are mountainous areas in the north and west of the country as well as plain areas located in central and eastern Iran, but there is no report on the incidence of CDV for hyenas in Iran, and the conservation status of striped hyenas and the potential impact of the disease on the hyenas' population or other carnivores is unclear. So, more studies are needed to investigate the presence of the virus, the level of the infection in regional and Iranian hyenas populations, and the type of virus strains and how the virus remains in the wild.…”

A 6‐month‐old free‐living female striped hyena (Hyaena hyaena) was referred to the Veterinary Teaching Hospital of Ferdowsi University of Mashhad, Mashhad, Iran with lethargy and seizures. The general and neurological examinations revealed normal heart rate, polypnoea, abnormal respiratory sounds, decreased consciousness and no postural reactions in limbs. The animal had generalised seizures every 20 minutes, lasting about 1 minute. To control seizures, 10 mg diazepam (0.7 mg/kg) was injected intravenously four times every 2 minutes. With this treatment, the animal's seizures stopped. Based on characteristic clinical signs, lymphopaenia, and positive rapid kit and RT‐PCR results, canine distemper virus (CDV) was confirmed. The animal developed general seizures again 12 hours after referral and died during the seizures. This is the first case report of status epilepticus due to CDV in a striped hyena that did not respond to anticonvulsant therapies and caused the death of the animal.
