Red-Necked Wallaby (Bennett’S Wallaby) Macropus Rufogriseus
Red-necked Wallaby (Bennett’s Wallaby) Macropus rufogriseus Class: Mammalia Order: Diprotodontia Family: Macropodidae Characteristics: Red-necked wallabies get their name from the red fur on the back of their neck. They are also differentiated from other wallabies by the white cheek patches and larger size compared to other wallaby species (Bioweb). The red-necked wallaby’s body fur is grey to reddish in color with a white or pale grey belly. Their muzzle, paws and toes are black (Australia Zoo). Wallabies look like smaller kangaroos with their large hindquarters, short forelimbs, and long, muscular tails. The average size of this species is 27-32 inches in the body with a tail length of 20-28 inches. The females weigh about 25 pounds while the males weigh significantly more at 40 pounds. The females differ from the males of the species in that they have a forward opening pouch (Sacramento Zoo). Range & Habitat: Flat, high-ground eucalyptus Behavior: Red-necked wallabies are most active at dawn and dusk to avoid forests near open grassy areas in the mid-day heat. In the heat, they will lick their hands and forearms to Tasmania and South-eastern promote heat loss. (Animal Diversity) These wallabies are generally solitary Australia. but do forage in small groups. The males will have boxing matches with one another to determine social hierarchy within populations. They can often be seen punching, wrestling, skipping, dancing, standing upright, grabbing, sparring, pawing, and kicking. All members of the kangaroo and wallaby family travel by hopping. Red-necked wallabies can hop up to 6 feet in the air. -
Energetics and Biomechanics of Locomotion by Red Kangaroos (Macropus Rufus)
Comparative Biochemistry and Physiology Part B 120 (1998) 41–49 Review Energetics and biomechanics of locomotion by red kangaroos (Macropus rufus) Rodger Kram a,*, Terence J. Dawson b a Department of Integrati6e Biology, Uni6ersity of California, Berkeley CA 94720-3140, USA b School of Biological Sciences, Uni6ersity of New South Wales, Sydney NSW 2052, Australia Received 15 May 1997; received in revised form 22 September 1997; accepted 7 October 1997 Abstract As red kangaroos hop faster over level ground, their rate of oxygen consumption (indicating metabolic energy consumption) remains nearly the same. This phenomenon has been attributed to exceptional elastic energy storage and recovery via long compliant tendons in the legs. Alternatively, red kangaroos may have exceptionally efficient muscles. To estimate efficiency, we measured the metabolic cost of uphill hopping, where muscle fibers must perform mechanical work against gravity. We found that −1 uphill hopping was much more expensive than level hopping. The maximal rate of oxygen consumption measured (3 ml O2 kg s−1) exceeds all but a few vertebrate species. However, efficiency values were normal, 30%. At faster level hopping speeds the effective mechanical advantage of the extensor muscles of the ankle joint remained the same. Thus, kangaroos generate the same muscular force at all speeds but do so more rapidly at faster hopping speeds. This contradicts a recent hypothesis for what sets the cost of locomotion. The cost of transport (J kg−1 m−1) decreases at faster hopping speeds, yet red kangaroos prefer to use relatively slow speeds that avoid high levels of tendon stress. © 1998 Elsevier Science Inc. -

Kangaroos, Dendrolagus Matschiei (Macropodidae), in Upper Montane Forest
Spatial Requirements of Free-Ranging Huon Tree Kangaroos, Dendrolagus matschiei (Macropodidae), in Upper Montane Forest Gabriel Porolak1,2,3*, Lisa Dabek3, Andrew K. Krockenberger1,2 1 Centre for Tropical Biodiversity and Climate Change, James Cook University, Cairns, Australia, 2 School of Marine and Tropical Biology, James Cook University, Cairns, Australia, 3 Department of Field Conservation, Woodland Park Zoo, Seattle, Washington, United States of America Abstract Tree kangaroos (Macropodidae, Dendrolagus) are some of Australasia’s least known mammals. However, there is sufficient evidence of population decline and local extinctions that all New Guinea tree kangaroos are considered threatened. Understanding spatial requirements is important in conservation and management. Expectations from studies of Australian tree kangaroos and other rainforest macropodids suggest that tree kangaroos should have small discrete home ranges with the potential for high population densities, but there are no published estimates of spatial requirements of any New Guinea tree kangaroo species. Home ranges of 15 Huon tree kangaroos, Dendrolagus matschiei, were measured in upper montane forest on the Huon Peninsula, Papua New Guinea. The home range area was an average of 139.6626.5 ha (100% MCP; n = 15) or 81.8628.3 ha (90% harmonic mean; n = 15), and did not differ between males and females. Home ranges of D. matschiei were 40–100 times larger than those of Australian tree kangaroos or other rainforest macropods, possibly due to the impact of hunting reducing density, or low productivity of their high altitude habitat. Huon tree kangaroos had cores of activity within their range at 45% (20.964.1 ha) and 70% (36.667.5 ha) harmonic mean isopleths, with little overlap (4.862.9%; n = 15 pairs) between neighbouring females at the 45% isopleth, but, unlike the Australian species, extensive overlap between females (20.865.5%; n = 15 pairs) at the complete range (90% harmonic mean). -

Eastern Grey Kangaroo Macropus Giganteus Shaw 1790 As a Vulnerable Species in Part 1 of Schedule 2 of the Act
NSW SCIENTIFIC COMMITTEE Preliminary Determination The Scientific Committee, established by the Threatened Species Conservation Act, has made a Preliminary Determination NOT to support a proposal to list the Eastern Grey Kangaroo Macropus giganteus Shaw 1790 as a Vulnerable species in Part 1 of Schedule 2 of the Act. Rejection of nominations is provided for by Part 2 of the Act. The Scientific Committee has found that: 1. Macropus giganteus Shaw 1790 (family Macropodidae), known as the Eastern Grey Kangaroo, is a large, highly sexually dimorphic macropod. Head-body to 2302 mm (males), 1857 mm (females); tail to 1090 mm (males), 842 mm (females); weight to 85 kg (males), 42 kg (females). Grey-brown dorsally, paler ventrally and on legs. Ears long, dark brown outside, pale grey inside with whitish fringe. Distal third of tail blackish. Muzzle finely haired (Menkhorst and Knight 2001; Johnson 2006; Coulson 2008). 2. Macropus giganteus is endemic to Australia. It is widely distributed in eastern Australia from Cape York Peninsula, Queensland, to far southeast South Australia and northeastern Tasmania. It is found throughout New South Wales (NSW). In western NSW, northwestern Victoria and southwestern Queensland M. giganteus is sympatric with its sister species the Western Grey Kangaroo (Macropus fuliginosus) (Johnson 2006; Coulson 2008). Eastern and Western Grey Kangaroos were recognised as separate species only in the 1970s (Kirsch and Poole 1972). Macropus giganteus mostly occurs where annual rainfall is >250 mm (Caughley et al. 1987b) in sclerophyll forest, woodland (including mallee), shrubland and heathland. It can also occur in modified habitats including farmland with remnant native vegetation, pine plantations and golf courses (Menkhorst and Knight 2001; Johnson 2006; Coulson 2008; Dawson 2012). -

Cercartetus Lepidus (Diprotodontia: Burramyidae)
MAMMALIAN SPECIES 842:1–8 Cercartetus lepidus (Diprotodontia: Burramyidae) JAMIE M. HARRIS School of Environmental Science and Management, Southern Cross University, Lismore, New South Wales, 2480, Australia; [email protected] Abstract: Cercartetus lepidus (Thomas, 1888) is a burramyid commonly called the little pygmy-possum. It is 1 of 4 species in the genus Cercartetus, which together with Burramys parvus form the marsupial family Burramyidae. This Lilliputian possum has a disjunct distribution, occurring on mainland Australia, Kangaroo Island, and in Tasmania. Mallee and heath communities are occupied in Victoria and South Australia, but in Tasmania it is found mainly in dry and wet sclerophyll forests. It is known from at least 18 fossil sites and the distribution of these reveal a significant contraction in geographic range since the late Pleistocene. Currently, this species is not listed as threatened in any state jurisdictions in Australia, but monitoring is required in order to more accurately define its conservation status. DOI: 10.1644/842.1.
