Abstract:

Captive parma and tammar wallabies, when offered ryegrass sward in plots, visited ungrazed plots more frequently and spent longer grazing on them than on plots that were previously grazed but not visibly depleted. There was no significant difference between the two species with respect to the pattern of time spent grazing between plots, but parma wallabies tended to visit ungrazed plots more frequently than tammar wallabies. When offered carrot pieces of different dimensions both species preferred carrot pieces of greater mass, regardless of shape. Both species favoured eating in the upright (

Abstract:

Non-invasive methods have the potential to circumvent problems associated with using more traditional techniques when surveying for rare and elusive species. In this study, non-invasive molecular-based methods have been used to analyse the scats of several species of marsupials. DNA was successfully extracted from scats of the quokka, Setonix brachyurus, and three other macropods (Macropus fuliginosus, M. irma and M. eugenii) sympatric with the quokka and with similar-appearing scats. Partial sequence from the mitochondrial cytochrome b gene from these four species and seven other macropods wa

Abstract:

A technique for trapping and immobilising small macropods is described and tested on forest-dwelling Tammar wallabies (Macropus eugenii Desmarest). The trapping method uses wire fencing and a monofilament nylon drop-net. The animals were immobilised with ketamine hydrochloride and xylazine. Tammar wallabies are reputedly hard to catch, but our technique produced higher trapping rates, lower trap-avoidance rates and lower death rates than other methods. In all, 46 Tammars were captured in 29 trap-nights. No deaths occurred during, or in the four weeks following, trapping.

We investigated the functional significance of molar progression and the influence of diet on the usefulness of molar progression as an index of age in two macropodid marsupials, the tammar wallaby (Macropus eugenii), a grazing species, and the parma wallaby (Macropus parma), a browser/grazer, by exploring the relationships between the index of molar progression and several skull and tooth parameters. We also tested allometric models that related molar progression and aspects of tooth morphology to body mass. Results support the notion that molar progression in these closely related macropods

Abstract:

Context Feral cats threaten wildlife conservation through a range of direct and indirect effects. However, most studies that have evaluated the impacts of feral cats on species of conservation significance have focussed on direct impacts such as predation; few studies have considered the indirect impacts of cat-borne disease. Toxoplasma gondii, a cat-borne parasite, causes both acute and latent disease in a range of wildlife species, and macropods are particularly susceptible. Kangaroo Island is Australia’s third largest island and supports a high density of feral cats and high seroprevalence

Abstract:

Competing theories of sex allocation in mammals may best be reconciled in the light of data from diverse species. The tammar wallaby (Macropus eugenii) is potentially a particularly interesting study animal because females wean only one young per year, and exhibit extreme synchronicity in the annual onset of breeding. By contrast, reproduction in the closely related parma wallaby (M. parma) is almost asynchronous. These two Australian species are found sympatrically only on Kawau Island, New Zealand, where they were introduced in about 1870. We sampled wallabies on Kawau Island in April of 199

Cytological, biochemical and anatomical characters are used. Fourteen living and 11 extinct species of Macropus are recognized.

The morphology of incisor and molar teeth of tammar wallabies (Macropus eugenii Desmarest) is similar to that of the archetypal grazing macropod (M. giganteus) but there are some resemblances in the wear pattern of molars to that of grazer/browsers. Incisor wear patterns show that cutting during biting is by scissor-like action of the elevated labial enamel edge of an attrition facet on each lower incisor being occluded with, and rotated supero-medially across, the buccal surface of the upper incisor arcade. With increase in age and body size, the cutting surface moves from anterior to lateral

Abstract:

Many of the 600 species of Acacia found in Australia form part of the diet of several groups of marsupials. Acacia foliage is generally high in tannins but is consumed by several folivorous possums and by some macropods (kangaroos and wallabies), but the macropods eat it mainly as dry leaf litter during times of food shortage (in dry seasons and drought). Acacia gum is an important diet component of two omnivorous possums (Petaurus breviceps, Gymnobelidius leadbeateri) and, to a lesser extent, two rat-kangaroos (Bettongia sp.). Acacia seeds are consumed by marsupials to a limited extent, but a

Abstract:

The feeding behaviour of four tammar wallabies (Macropus eugenii Desmarest) inhabiting a bush pasture ecotone in the Rotorua district of North Island, New Zealand, is described. Feeding activity, monitored by feeding sounds, was crepuscular. Mastication effort, as daily eating time corrected for metabolic body weight and weight-related change in tooth surface area, was similar to that of the red kangaroo, a species of greater equivalent dry-matter intake. Grazing events were significantly longer than browsing events, and feeding events longer than 100 sec comprised 66.5% of total feeding activ

Abstract:

The tammar wallaby, Macropus eugenii, has a seasonal breeding cycle which is dependent upon the light regime. Females normally produce one pouch young a year, while carrying a diapausing blastocyst in the uterus. Before the winter solstice, the sucking stimulus of lactation is responsible for inhibition of blastocyst development (lactational quiescence); after this time, inhibition is caused by increasing day length (seasonal quiescence). Lactational quiescence can be broken by removal of the developing young in the pouch, and seasonal quiescence by artificial light regimes, or melatonin treat

Abstract:

Milk consumption rates of young tammar wallabies, Macropus eugenii, were measured during the first 32 weeks of lactation by means of 22*Na turnover. Milk consumption rates were low during the first 18 weeks or so of lactation, rising from 1.2 to 9.0 ml d-'. Milk consumption rose to 43 ml d-' at 30 weeks post-partum. Changes in milk consumption were paralleled by increases in the size of mammary glands and weight gain by the sucklings. The mass gain for each millilitre of milk consumed (crude growth efficiency) averaged 0.23 g ml-I during the first 26 weeks of lactation, but then increased to m

Abstract:

The gross morphology of the body and gastrointestinal tract of genetically-similar tammar wallabies (Macropus eugenii) that had been introduced into two different nutritional environments on the North Island of New Zealand were compared using multivariate analysis. Tammar wallabies from Kawau Island had significantly lower body mass per unit body length than those from the Rotorua district where food was more abundant. Furthermore, wallabies from Kawau Island had longer small intestines and caecae relative to other gut regions than did those from the Rotorua district. This suggests that poor-q

The slope coefficient of the regression describing variation of whole gut content with body weight was not significantly different from isometry.

Abstract:

SUMMARY Marsupials are born at an early stage of development and are adapted for future development inside the pouch. Whether the pulmonary surfactant system is fully established at this altricial stage is unknown. This study correlates the presence of surfactant proteins (SP-A, SP-B and SP-D), using immunohistochemistry, with the ex-utero development of the lung in the tammar wallaby Macropus eugenii and also investigates the control of phosphatidylcholine (PC) secretion from developing alveolar type II cells. All three surfactant proteins were found at the site of gas exchange in the lungs o

Abstract:

Apparently once widespread throughout dense thickets in south-western Australia, the tammar is now much restricted in its distribution. On mainland Australia, isolated populations still persist in Western Australia, but in South Australia, where there is little remaining evidence to confirm that it extended beyond Eyre Peninsula, the wallaby is probably close to extinction. All originally recorded populations on five islands in Western Australia remain, but in South Australia all natural island populations, other than those on Kangaroo I., appear to be extinct.

Reported differences between these species in their rates of molar progression with age may therefore result from dif
