In contrast, the equine fossil record shows that an extraordinarily richer diversity existed in the past and provides multiple examples of a highly dynamic evolution punctuated by several waves of explosive radiations and extinctions, cross-continental migrations, and local adaptations. -
Age Determination of the Mongolian Wild Ass (Equus Hemionus Pallas, 1775) by the Dentition Patterns and Annual Lines in the Tooth Cementum

The dentition pattern allows identification of age up to five years. We also conclude that annual lines in the tooth cementum can be used to determine the age in years for wild asses older than five years after longitudinal tooth sections were made with a low- speed precision saw. The first upper incisor proved to be most suitable for age determination, although the starting time of cement deposition is different between the labial and lingual sides of the tooth. The accurate age of the wild ass can be determined from the number of annual lines and the time before the first forma- tion of the cementum at the respective side of the tooth.

D., Dip. E.C.V.A.A. Abstract: General anesthesia poses risks for larger zoo species, like cardiorespiratory depression, myopathy, and hyperthermia. In ruminants, ruminal bloat and regurgitation of rumen contents with potential aspiration pneumonia are added risks. Thus, the use of sedation to perform minor procedures is justified in zoo animals. A combination of detomidine and butorphanol has been routinely used in domestic animals. This drug combination, administered by remote intramuscular injection, can also be applied for standing sedation in a range of zoo animals, allowing a number of minor procedures. The combination was successfully administered in five species of nondomesticated equids (Przewalski horse [Equus ferus przewalskii; n ¼ 1], onager [Equus hemionus onager; n ¼ 4], kiang [Equus kiang; n ¼ 3], Grevy’s zebra [Equus grevyi; n ¼ 4], and Somali wild ass [Equus africanus somaliensis; n ¼ 7]), with a mean dose range of 0.10–0.17 mg/kg detomidine and 0.07–0.13 mg/kg butorphanol; the white (Ceratotherium simum simum; n ¼ 12) and greater one-horned rhinoceros (Rhinoceros unicornis; n ¼ 4), with a mean dose of 0.015 mg/kg of both detomidine and butorphanol; and Asiatic elephant bulls (Elephas maximus; n ¼ 2), with a mean dose of 0.018 mg/kg of both detomidine and butorphanol. -

Zebra and Quagga Mussels
SPECIES AT A GLANCE Zebra and Quagga Mussels Two tiny mussels, the zebra mussel (Dreissena poly- morpha) and the quagga mussel (Dreissena rostriformis bugensis), are causing big problems for the economy and the environment in the west. Colonies of millions of mussels can clog underwater infrastructure, costing Zebra mussel (Actual size is 1.5 cm) taxpayers millions of dollars, and can strip nutrients from nearly all the water in a lake in a single day, turning entire ecosystems upside down. Zebra and quagga mussels are already well established in the Great Lakes and Missis- sippi Basin and are beginning to invade Western states. It Quagga mussel takes only one contaminated boat to introduce zebra and (Actual size is 2 cm) quagga mussels into a new watershed; once they have Amy Benson, U.S. Geological Survey Geological Benson, U.S. Amy been introduced, they are virtually impossible to control.

Sacramento Zoo Reports the Death of Geriatric Grevy's Zebra
Sacramento Zoo Reports the Death of Geriatric Grevy’s Zebra WHAT’S HAPPENING: The Sacramento Zoo is mourning the loss of Akina, a geriatric female Grevy’s Zebra. WHEN: Akina passed away the evening of Thursday, December 29 at the age of 24. On December 28, Akina was behaving abnormally and was placed under veterinary observation and treatment for suspected colic. Colic is a relatively common, but serious, disorder of the digestive system. The next day, after her conditioned failed to improve, Akina was brought to the Sacramento Zoo’s veterinary clinic where she received a full exam. During the exam, Akina was given fluids, pain medications, antibiotics, intestinal protectants and mineral oil to assist with resolving the colic. Over the course of the afternoon Akina was slow to recover from the exam and unfortunately died at the end of the day. Akina was taken to UC Davis for a full necropsy. Born in 1992, Akina was the second oldest Zebra at the Sacramento Zoo, and one of the oldest Grevy’s Zebras living at an Association of Zoos and Aquariums-accredited institution – the oldest being 27 years-of-age. “Akina was a Grand Old Equine who was never shy about chatting,” said Lindsey Moseanko, Primary Ungulate Keeper at the Sacramento Zoo. “Her vocalizing could be heard throughout the zoo. She loved coming to her keepers at the fence-line for apple slices and ear scratches,” she continued. “Her spunky personality will be missed.” The Sacramento Zoo participates in the Association of Zoos and Aquariums’ Grevy’s Zebra Species Survival Plan®. -

They were first introduced to ships discharging ballast water that contained adult or larval mussels. They spread widely and as of 2019, can be found in Ontario, Quebec and Manitoba. They are now established in at least Alberta24 American or the states. north. Quagga and zebra mussels have not yet been detected in BC, Saskatchewan, IDENTIFICATION Zebra and quagga mussels—or dreissenid mussels— look very similar, but quagga mussels are slightly larger, rounder, and wider than zebra mussels. Both species range in colour from black, cream, or white with varying amounts of banding. Both mussels also possess byssal threads, strong fibers that allow the mussel to attach itself to hard surfaces—these are lacking in native freshwater mussels. There are other bivalve species found within BC (see table on reverse). waters to be distinguished from zebra and quagga IMPACTS ECOLOGICALmussels CHARACTERISTICS Ecological: Once established, invasive dreissenids are nearly impossible to fully eradicate from a water body.

The Indian Wild Ass—Wild and Captive Populations
The Indian wild ass —wild and captive populations Jan M. Smielowski and Praduman P. Raval The ghor-khar is a rare subspecies of onager, or Asiatic wild ass, and its habits are little known. The only known wild population inhabits the Little Rann of Kutch Desert in Gujarat State in western India and, after its numbers fell dramatically in the 1960s, it was declared a protected species. Conservation measures, including the establishment of a Wild Ass Sanctuary in 1973, have been so successful that the most recent census, in 1983, recorded nearly 2000 individuals, compared with 362 in 1967. The authors made four visits to Gujarat to study wild asses between 1984 and 1986. The Indian wild ass or ghor-khar Equus hemionus juliflora. According to Shahi (1981), between khur is endemic to the Indian subcontinent.

It is a polygynous northern Gujarat State, western India. This saline species, an adult stallion leading a group of mares desert is a unique ecosystem with very specific and young. The females are always white on the flora and fauna.

Biological data 2.1 Distribution: During the late Pleistocene, 40.000 years ago, Asian wild asses are known to have roamed as far as West Germany (Kurten 1968, cited in Feh et al. 2001). The Asiatic wild ass Equus hemionus, or khulan, once ranged across much of Central Asia, but is now globally threatened. The largest free-ranging populations are now restricted to a 250-km wide area (range 100-400km) across the Gobi Desert region of southern Mongolia. Over the last 23 years the population has moved further north and east into its former range (Reading et al. 2001). Mongolia represents one of the last strongholds for Asian wild asses, a wide ranging species that inhabits the Middle East (E.h.onager), Central Asia (E.h.kulan), parts of India (E.h.khur), and the Gobi desert of China and Mongolia (Reading et al. -
African Wild Ass the African Wild Ass Is Endangered
tion. Equus africanus is not listed on the CITES appendices, according to the Secretariat, simply African because nobody ever proposed it—even though it is classified as endangered in the IUCN's Red Data Book where the first proposed conservation measure listed is inclusion in Appendix I of the wild ass Convention on International Trade in Wild Bill Clark Species (sic) of Fauna and Flora. This proposal was published in 1976. While conservationists have been slow to propose protective measures for this rare equine, the international animal exploiters have also been stalled for the time being. The African wild ass The African wild ass is endangered. Its lives in an extremely remote and hostile habitat, habitat is a drought-stricken war zone; its in countries where the political situation is, at best, flesh is eaten and is believed to cure unstable. hepatitis; it is eagerly sought by dealers Two subspecies now exist, africanus, the Nubian and collectors.
