  Wallaby - July Animal of the Month
Wallabies are marsupials from the islands of Australia, Tasmania, New Zealand (introduced), and New Guinea.
Tammar Wallabies are also found in New Zealand where they were transported from the South Australian mainland population which has since been driven to extinction by feral cats and foxes.
Red-necked Wallabies (Bennett's) are distinguished by their fl nose and paws, white stripe on the upper lip, and grizzled medium grey coat with a reddish wash across the shoulders.

 Biodiversity - Threatened Species - Tammar Wallaby
Eighty-five Tammar Wallabies were successfully repatriated from New Zealand in 2003-2004 and were held in quarantine for twelve months at the Monarto Zoological Gardens, pending a full assessment of their state of health.
In the case of Tammar Wallabies, this procedure entails the careful removal of small pouch young from the captive bred mainland Tammar mothers and the placement of these young into the pouches of Kangaroo Island Tammars.
Tammar Wallabies are particularly susceptible to predators and it is highly likely that the Kangaroo Island wallabies would also be extinct today, if Foxes had established themselves on Kangaroo Island.

In fact, wallabies are much more susceptible to heat stress if they cannot find sufficient shade and water than they are to stress caused by low temperatures.
Additional bedding is added to the corners where they tend to lie down and they are given warm oatmeal with salt and vitamin E mixed in and sweetened with honey in the morning and the evening in addition to their regular feed.

 Journal of Vision - Color opponent retinal ganglion cells in the tammar wallaby retina, by   (Site not responding. Last check: 2007-10-10)
The peak spectral sensitivities of wallaby cone photoreceptors have been estimated to be 539 nm for the middle wavelength-sensitive cone and 420 nm for the short wavelength-sensitive cone (Hemmi, 1999; Hemmi, Maddess, and Mark, 2000).
The action spectra of the two wallaby cone types (peak for M cones at 539 nm and for S cones at 420 nm) overlap with the spectra of the three stimulus phosphors, and, therefore, each kernel in Figure 2A represents contributions from both M- and S-cone pathways, albeit at different ratios.
Unlike wallaby, the commonly found color opponent ganglion cells in primates and cats are S-on/M-off (Cleland and Levick, 1974; Dacey and Lee, 1994; Chichilnisky and Baylor, 1999), although rarely encountered M-on/S-off cells have been described in the lateral geniculate nucleus of monkeys (Valberg, Lee, and Tigwell, 1986).

Griffin chose tammar wallabies because they are almost extinct in their native Australia, thanks mostly to foxes, but they manage to survive on islands, such as Kangaroo Island, and in New Zealand where large predators are absent.
"Tammars seem to have some innate predisposition to recognise predators, but their response is not sufficient for them to survive if they encountered a fox or cat in the wild," she says.
The wallabies soon came to associate the fox with the arrival of a human, and would become alarmed at the sight of the fox alone," she says.

 Stuffed fox teaches wallabies to fear predators - 23 January 2002 - New Scientist
Harassing wallabies could be the next big thing in Australia, not as a hobby for mindless thugs, but in order to protecting the species.
By showing tammar wallabies a stuffed fox and then chasing them with a net, biologists have taught captive-bred tammars to be more afraid of the predators that helped make them extinct across much of mainland Australia.
Tammars are usually only mildly fearful of foxes and cats, which were introduced by European settlers.

 Enzymes of galactose metabolism in livers of suckling and adult tammar wallabies (Macropus eugenii) and other marsupials   (Site not responding. Last check: 2007-10-10)
Activities of galactokinase, UDPglucose-hexose-1-phosphate uridylyltransferase and UDPglucose 4-epimerase in homogenates of livers of 2 adult and 20 suckling tammar wallabies aged 6 to 50 wk were investigated.
Activities of the enzymes in suckling tammar wallabies and suckling rats showed no difference in regard to galactokinase and UDPglucose-hexose-1-phosphate uridylyltransferase, but UDPglucose 4-epimerase activity in tammar wallabies was approx.
This may be related to the high galactose content of tammar wallabies' milk compared with rats' milk.

Effect of gonadectomy, season and the presence of female tammar wallabies (Macropus eugenii) on concentrations of testosterone, luteinizing hormone and follicle-stimulating hormone in the plasma of male tammar wallabies
Concentrations of FSH, LH and testosterone in plasma were measured in groups of adult male tammar wallabies before and after gonadectomy, and during the breeding and non-breeding seasons.
However, when male wallabies were associated with sexually mature females there were significant three- to fourfold increases in concentrations of LH and testosterone in plasma at the commencement of the breeding season.

The wallabies did not seem to mind the transition, taking to island life with relish, rapidly growing in number and becoming a pest.
So plentiful had the wallabies become by the 1990s that the NZ Department of Conservation considered eradication because of the effect they were having on native plants and birds.

DNA sampling has established that an introduced colony of tammar wallabies living on Kawau Island, 55 kilometres north-east of Auckland, is almost certainly comprised of the descendants of a wallaby subspecies that vanished from mainland South Australia in the early 1900s.
Island residents occasionally cull the wallabies and the marsupials are regularly exported to zoos and fauna parks in 15 countries.
The two other wallaby species residing on Kawau Island, the parma and the brush-tailed rock wallaby, are also potentially valuable conservation resources, as their Australian counterparts have suffered severe population declines in recent years.

 Time allocation in tammar wallabies   (Site not responding. Last check: 2007-10-10)
We studied the degree to which competition for food inuenced the time tammar wallabies (Macropus eugenii) allocate to foraging and vigilance by experimentally manipulating access to food, while holding other factors constant.
Groups of six wallabies were observed when they had access to either one or six non-depleting bins of supplemental food.
These results, when combined with other findings, suggest that the moderately social tammar wallaby receives an antipredator benefit by aggregating with conspeci€cs which is not reduced significantly by foraging competition.
