Feral Chital Deer Axis Axis (Sometimes Known As Axis Deer Or Indian Spotted Deer) Restricted invasive animal Feral chital deer Axis axis (sometimes known as axis deer or Indian spotted deer) Originally introduced in the 19th century from Europe and Legal requirements Asia as game animals by European settlers, Australia is now home to six species of deer; fallow, red, chital, hog, Feral chital deer is a restricted invasive animal under the rusa and sambar. Queensland is home to four of the six Biosecurity Act 2014. It must not be moved, fed, given species; fallow, red, chital and rusa. away, sold, or released into the environment without a permit. The Act requires everyone to take all reasonable While deer continue to be farmed for venison, the wild and practical steps to minimise the risks associated with populations are causing significant environmental invasive plants and animals under their control. This is damage. They can damage crops, pastures and forestry called a general biosecurity obligation (GBO).

Distribution of feral chital deer in Queensland animal (feral) if a person is keeping it in a deer proof enclosure and has become a registerable biosecurity entity (RBE) to keep that designated animal. Feral chital deer can be considered as designated animals if a person keeps them. Generally the minimum escape proof enclosure for farmed deer or an exclusion fence for feral deer is a well maintained high netting fence or equivalent. An example of an effective deer fence is one that is 2.1 m high, has strainers and posts made of heavy duty material such as hardwood or metal that are set deeply into the ground and no more than 9 m apart. The netting would be 17/190/15 or 13/190/30 for chital deer, supported by well strained top, bottom and belly wires and pegged securely to the ground. Gates would be of similar standard and the same height. Fence lines should preferably be cleared to minimise trees falling on the fence. Note that this is an example only and fence construction should be appropriate for the individual circumstances. Description Chital deer have a rusty red to dark brown coat with permanent white spots appearing as broken lines along the body. Other distinguishing features are their prominent white throat and large tail. Adult stags stand up to 95 cm at the shoulder, while hinds are smaller. Adult stags weigh 75–100 kg, hinds up to 50 kg. Stags have three tined antlers on a long, upright beam, 55–70 cm. The main Charters Towers herd is estimated to number Life cycle around 10 000 animals, although numbers can fluctuate The breeding season is non-seasonal, although fertility significantly between good seasons and drought.

J. DOBRORUKA Zoological Garden, Prague With 2 text-figures and 3 plates A great number of papers deal with the deer of the Philippine Islands but in spite of this fact the taxonomy and the nomenclature are still not clear. The first author who recapitulated all known facts about the Philippine deer was Brooke (1877), who also described a new species, Cervus nigricans. The description is exact, with figures of the habitus and the skull of the indicated holotype (♀), and in my opinion Haltenorth (1963) had no reason to con- sider C. nigricans a nomen nudum. The validity of the name Cervus nigricans is in full agreement with the International Code of Zoological Nomenclature, adopted by the XVth International Congress of Zoology. Cervus nigricans is rather rare in the collections of museums and, there- fore, I am much obliged to Dr. A. M. Husson for allowing me to examine the material of the Rijksmuseum van Natuurlijke Historie in Leiden. The material of this museum was mentioned already in Brooke's paper (1877:59) and is therefore most valuable for a study of this species, apart from the type material, of course. At the present time the following material of this species is available in the Leiden Museum: No. 19605 ♂ — mounted specimen and skull from Manila, Philippines. Presented by M.

  • Handraising Exotic Animals Western Plains
    HANDRAISING EXOTIC ANIMALS WESTERN PLAINS ZOO GENERAL DIRECTIVES: * All neonates (newborn) to be given colostrum for the first 24 - 36 hours where possible. Bovids, cervids, camelids, hippos etc. (order: Artiodactyla) to receive bovine colostrum. Equids, tapir, rhinos etc. (order: Perissodactyla) to receive equine colostrum. * All milk formulas to be gradually increased to 100% strength concentrations as recommended. i.e. Commence at 25% - 50% concentrations supplemented with vytrate, staged up by 25% at 24 hour intervals until 100% is reached. Use pre-boilded water to make up formulas. * Young to be fed 12 - 20% of their bodyweight in milk formula each day, divided equally between feeds. If innadequate volumes of formula are suckled then the neonate is to be tube fed until intake is adequate from the bottle. * Number of feeds per day is determined by species. * Weigh initially and weight gain/loss to be monitored at least weekly. * Routine is extremely important. Feeding times must be set and adhered to. It is usually better for one person to initiate feeding and to introduce other feeders as soon as possible to avoid neonates imprinting on one person. * All young need to be stimulated to urinate and defaecate after each feed by gentle patting - never rub. Ensure they are left clean afterwards. * Hygiene is of great importance. Bottles and teats need to be washed thoroughly and soaked in sterilising solution (Halasept). Utensils are to be rinsed with pre-boiled water before use. Face wipes are not shared with anus wipes etc. Cloths to be washed daily. All young to be left with a clean mouth after the feed (includes chin, lips etc.) * Milk temperature is to be fed at body temperature.

  • I Vividly Remember Reading About the Discovery of the Saola (Pseudoryx
    I vividly remember reading about the discovery of the Saola (Pseudoryx nghetinhensis) in the BBC Wildlife Magazine whilst sitting in my traditional English school library. I was transfixed by the discovery of a distinctive, one-and-a-half-meter long, 70 kilogram ungulate with long tapered horns in the forests of Vietnam. I vowed there and then to work on and help the species however I could. Twenty-six years later I am still keeping that vow, but time is running out. It is going to take an incredible effort to stave off extinction and put the Saola on the path to recovery toward a fully functioning population. The discovery of the Saola in 1992 has been heralded as one of the most spectacular zoological discoveries of the 20th century, not only because of the size and beauty of the species, but also because of its phylogenetic distinctiveness; the Saola sits alone in a monotypic genus. Its morphological and genetic characteristics suggest it is a primitive member of the tribe Bovini, along with the cattle and buffalo, within the family Bovidae. The Saola is found in the North and Central Annamite Mountains of Vietnam and Laos where it is restricted to climatically wet evergreen, broadleaf forest habitats. These forests are subjected to an up to 10-month long rainy season, with no month receiving less than 40 mm of rain. This level of rainfall is the result of two monsoons, and determines the Saola’s distribution. The western and southern distribution of the Saola are bounded by the rain shadow of mountain chains with the western extent expanding deeper into Laos where the mountains dip, allowing deeper penetration of the northeast winter monsoon.

Feral deer in Australia - background Deer are hard-hoofed mammals (ungulates) of family Cervidae with a native distribution over Eurasia and the Americas. The first successful introductions into Australia were by acclimatisation societies in the 1800s. A history of their introduction can be found in Moriarty (2004). Of 18 species released, six species of three genera have established populations that currently survive and are the subject of this nomination (for a description see Van Dyck and Strahan 2008 and section 2 here): - Chital (Axis axis) - Hog Deer (Axis porcinus) - Red Deer (Cervus elaphus) - Rusa Deer (Cervus timorensis) - Sambar (Cervus unicolor) - Fallow Deer (Dama dama) Feral populations have established due to release by acclimatisation societies (7% of 218 populations identified in 2002); escapes and releases from deer farms (35%); and translocations, presumably for hunting (58%) (Moriarty 2004). The rapid growth in deer farming in the 1970s-80s (an annual 25% increase in the number of farmed deer) has been the source for the recent expansion in wild deer populations (Jesser 2005).

Despite new input from molecular systematics, consensus could only be partially reached. The initial, gross (sub)classification based on morphology and comparative anatomy was mostly supported by molecular data. The rich fossil record of cervids has never been extensively tested in phylogenetic frameworks concerning potential systematic relationships of fossil cervids to extant cervids. The aim of this work was to investigate the systematic relationships of extant and fossil cervids using molecular and morphological characters and make implications about their evolutionary history based on the phylogenetic reconstructions. To achieve these objectives, molecular data were compiled consisting of five nuclear markers and the complete mitochondrial genome of 50 extant and one fossil cervid species. Several analyses using different data partitions, taxon sampling, partitioning schemes, and optimality criteria were undertaken.
