Wild ungulates in Jordan: past, present, and forthcoming opportunities

Twelve species of ungulates are reported from the wild in Jordan. Three of these, Addax nasomaculatus (Addax), Bos primigenius (Aurochs), and Cervus elaphus (Red Deer) are known only from archaeological excavations. Dama mesopotamica (Mesopotamian Fallow Deer), Oryx leucoryx (Arabian Oryx) and Equus hemionus hemippus (Syrian Wild Ass) have been regionally extirpated in the wild. A semi-captive population of Persian Onager (E. h. hemionus) is held in Shumari Wildlife Reserve. The Arabian Oryx is also managed in semi-captive conditions in two reserves. Except the commonly occurring Wild Boar (Sus scrofa), other surviving ungulate species continue to be under serious threat. Gazella gazella (Palestinian Mountain Gazelle), Capreolus capreolus (European Roe Deer), Gazella marica (Arabian Sand Gazelle), and Gazella dorcas (Dorcas Gazelle) are Critically Endangered, and Capra nubiana (Nubian Ibex) is Endangered in the region. This paper provides a review of the historical and current status of wild ungulates in Jordan, listing the threats and conservation measures and provides recommendations for management and conservation in the future.

Post-release Movement Behaviour and Survival of Kulan Reintroduced to the Steppes and Deserts of Central Kazakhstan

Asiatic wild ass, or kulan (Equus hemionus kulan) were once a key species of the Eurasian steppes and deserts. In Kazakhstan they went extinct by the 1930s. Early reintroductions have reestablished the species in two protected areas, but the species has reclaimed <1% of their former range and remained absent from central Kazakhstan. To initiate restoration in this vast region, we captured and transported a first group of nine wild kulan to a large pre-release enclosure in the Torgai region in 2017, and two more in 2019. We used direct observations and post-release movement data of four kulan equipped with GPS-Iridium collars to document their adaptation process in a vast novel habitat without conspecifics. For comparison with movements in the source populations, we additionally equipped two kulan in Altyn Emel National Park and six in Barsa Kelmes State Nature Reserve. The nine transported kulan formed a cohesive group with very high movement correlation in the enclosure. After release, the group initially stayed tightly together but started to break up by mid-May and all kulan travelled independently by mid-August. With 48,680–136,953 km2, the 95% Autocorrelated Kernel Density Estimation ranges of the reintroduced kulan were huge and about 10–100 times larger than those in the source populations. The reintroduced mares never reconnected, there was no evidence of successful reproduction, and two of the four collared mares were killed by poachers and one died of natural causes. At least one stallion survived in the wild, but the fate of the other uncollared animals remains unclear. We speculate that the fission-fusion dynamics and low movement correlation of kulan societies and the need for migratory movements harbours the risk that animals released into a novel environment loose contact with each other. This risk is likely enhanced in steppe habitats where movement constraining factors are absent. Further kulan reintroductions to the steppes and deserts of central Kazakhstan should aim to release larger groups and build up the free-ranging population quickly to reach a critical mass, increasing the chance of kulan encountering conspecifics to successfully breed and increase their chances of survival.

Integrating spatial analysis and questionnaire survey to better understand human-onager conflict in Southern Iran

Southern Iran is a conservation priority area for the endangered Persian onager (Equus hemionus onager), which is threatened by habitat fragmentation and conflict with local communities. To better understand factors that influence onager conservation, we administered a questionnaire in local communities to survey their ecological knowledge, personal experience related to onager, and attitudes toward traditional solutions for reducing crop damage by onager. In addition, we used resistant kernel and factorial least-cost path analyses to identify core areas and corridors for onager movement, and spatial randomization of vehicle collisions and crossing locations to test the predictive ability of resistant kernel and factorial least-cost path predictions of movement. We found that local communities that were knowledgeable about onagers experienced less crop damage from onager compared with those who used traditional methods. Habitat connectivity models revealed that core areas of movement are highly concentrated at the center of protected areas. Some sections of core areas have been cut off by roads where most vehicle collisions with onagers occurred. We propose that effective onager conservation will require integrated landscape-level management to reduce mortality risk, protection of core areas and corridors, development of mitigation strategies to reduce vehicle collisions, and conflict mediation between local communities and onagers.

Dynamics of Gastro-Intestinal Strongyle Parasites in a Group of Translocated, Wild-Captured Asiatic Wild Asses in Kazakhstan

Asiatic wild ass (Kulan, Equus hemionus) population range and numbers became severely reduced and a reintroduction project is currently aiming to re-establish a population in the Central Steppe of Kazakhstan. Pre-emptive deworming is often recommended for equid translocations but eliminating parasites prior to translocation could cause disruptions in a balanced host-parasite relationship, adding an additional stressor to an already stressful intervention involving capture, transport, and adaptation to a new environment. Following a disease risk assessment, we decided against pre-emptive deworming and focused on monitoring the first group of nine translocated kulan in a large acclimatization enclosure prior to release. Over the 5-month acclimatization period, we regularly collected fecal samples and analyzed the shedding intensity of gastro-intestinal parasite eggs, obtained time budgets through behavioral observations, and visually assessed body condition. We identified strongyles (Strongylinae and Cyathostominae) and pinworms (Oxyuris equi) in fecal samples. All individuals shed strongyle eggs and two of the nine individuals had higher shedding intensities, but rarely reached levels for which deworming is recommended. All kulan appeared healthy throughout the observation period, aggressive interactions were very rare, and time budgets were very similar and dominated by feeding. Our results suggest that in translocation projects where the risk of introducing new parasites is minimal, pre-emptive treatment in wild equids can be replaced with non-invasive monitoring during the acclimatization period. We acknowledge that the small number of kulan, the large size of the enclosure, and the low temperatures during the animals stay in the acclimatization enclosure may all have reduced infestation pressure.

OSTEOLOGICAL MATERIALS FROM CARAVANSERAI SHENGELDY

The article discusses osteological material from the excavations of the Shengeldy caravanserai. In the descriptions of the representatives of the fauna from the medieval caravanserai of Shengeldy and in table 1, the majority of bone remains are identified to a species. Examination of the species composition of the fauna shows their not rich species composition, although as a result of the study all species of domestic ungulates are found. Bone remains were determined by species, skeleton elements and degree of fragmentation. Bones found: horses (Equus caballus), cattle (Bos taurus), sheep (Ovis aries), goats (Capra hircus) and camel (Camelus bactrianus); wild animals - kulan (Equus hemionus), saiga (Saiga tatarica) and turtles (Testudines). Among domestic animals, the bones of horses and small cattle prevail. Cattle ranks third in number. One camel bone was found. Of the bones of domestic animals, 23.4% were intact and 76.6% were fragmented. Among the departments of the skeleton of domestic ungulates, carcass bones (scapula, vertebrae, ribs) and upper legs (femurs and tibia) predominate. Several fragments of human bones were found. Morphometric studies of the bones of horses, sheep, goats and cattle were carried out. Geometric morphometric methods have revealed morphological differences and similarities between species.

Metatranscriptomics reveals that the death of a Mongolian wild ass was caused by Clostridium botulinum in Inner Mongolia, China

Clostridium botulinum is an important pathogen that causes botulism in humans and animals worldwide. C. botulinum group III strains, which produce a single toxin of type C or D or a chimeric toxin of type C/D or D/C, are responsible for botulism in a wide range of animal species including cattle and birds. We used unbiased high-throughput RNA sequencing (i.e., metatranscriptomics) to identify a strain of group III C. botulinum from a deceased Mongolian wild ass ( Equus hemionus). The strain was closely related to some European strains. Genetic analysis of the recovered bacterial sequences showed that the C. botulinum strain identified might represent a type C/D strain of group III. Infection by C. botulinum producing the mosaic toxin of type C/D is the most likely cause of the death of the wild ass.
