Placentals have spread to all parts of the globe, and where placentals have competed with marsupials, the placentals have in general displaced marsupial types. However, marsupials occupy many specialized niches in South America and, especially, Australasia. The theory that marsupials succeed only where they do not compete with placentals was shaken in 1992, when a tooth, 55 million years old and belonging to a placental mammal, was found in Murgon, Australia, indicating that placental animals appeared in Australia at the same time as the marsupials. The marsupials, however, still prevailed. There are over 4,000 species of mammals, adapted to almost every way of life. The smallest shrew weighs only 2 g/0.07 oz, the largest whale up to 140 tonnes. A 50-million-year-old jaw discovered in 1998 is from the smallest mammal ever to have lived

Koala Bears - Range and Habitat Picture source: Headweb com Koalas are found in eucalyptus woodlands of eastern Australia. These mammals use the eucalyptus tree as food and home. Therefore, they are greatly dependent on eucalyptus forests. Reduction of habitat is considered the number one threat for the Koala Bear. Once abundant on the territory of the whole continent, Koalas range is now restricted to a few areas in Australia. Koala Bears - Feeding Habits Despite a great number of eucalyptus tree species, the Koala Bear prefers just a few of them. This bear-like mammal feeds on only about 35 eucalyptus species of 800+ ones known. Koalas are mainly nocturnal animals. They explore eucalyptus trees in search of succulent leaves at night. It is interesting to note that Koala's water needs are met with these leaves. The Koala almost never drinks. The name of the species translates from aboriginal language as a "no drink animal." Koalas have a well-designed digestive system that allows them to do well on low in protein and rich in fiber eucalyptus leaves. Due to Koala's slow metabolism rate, food remains up to 100 hours in the digestive system. The nutritional processes of the species are adjusted to extract the most energetic value from the food. The caecum, a fiber-digestive organ, is one of the Koala's adaptations.

ANSCI 308 Lactation Biology Lactation in Marsupials W L Hurley Department of Animal Sciences University of Illinois Urbana-Champaign This lesson has sections discussing aspects of the Lactation in Marsupials, including: Introduction Evolution of Marsupials Neonate Development Reproductive Strategy Lactation Milk Composition References Return to Comparative Lactation Biology Return to Lactation Biology Topic Areas Introduction Marsupials evolved from ancestral therian mammals (which give birth to live young, but have no true placenta) over 80 million years ago; well before the demise of the dinosaurs. Eutherian mammals (which have a true placenta) also evolved from therian mammals, but evolved independently from marsupials. Although we are most familiar with marsupials like the American opossum and images of the Australian kangaroos and koalas, there are about 250 species of marsupials. However, in terms of lactation biology, most of what we know is derived from study of kangaroo species. Limited evidence from other marsupial species indicates that we can expect many similarities in strategies of lactation among most marsupials, so the kangaroo species makes an acceptable general model for much of the Order Marsupialia. Nevertheless, significant differences among marsupial species likely will be found as more species are studied. Marsupials do seem to have the potential for an extended gestation, but this has not been exploited evolutionarily. This suggests that the emphasis on lactation, as opposed to intrauterine development, should be viewed as an alternate reproductive strategy and not as a more primitive form of mammalian reproduction. Despite the immature development of the newborn marsupial, they nevertheless can travel (unaided by the mother) from the birth canal to the mammary area or pouch and can attach to a teat and begin to suck. In addition, they are able to breath the atmosphere of the pouch.

Almost all museum specimens in existence were collected by Aboriginal people, who call the animals itjaritjari, and the few animals held in captivity died within weeks. Despite the rarity of marsupial moles on the desert surface, introduced predators like foxes and cats apparently have little problem preying on them. Like most other endemic Australian mammals in their size range, itjaritjari populations may be seriously endangered by these predators. You will collaborate with indigenous leaders of Anangu-Pitjantjatjara Land Management to conduct the first-ever study of the ecology and behavior of the marsupial mole.

Mutual Affinities of Organic Beings: Morphology Embryology Rudimentary Organs On the nature of the affinities connecting organic beings As the modified descendants of dominant species, belonging to the larger genera, tend to inherit the advantages which made the groups to which they belong large and their parents dominant, they are almost sure to spread widely, and to seize on more and more places in the economy of nature. The larger and more dominant groups within each class thus tend to go on increasing in size, and they consequently supplant many smaller and feebler groups. Thus, we can account for the fact that all organisms, recent and extinct, are included under a few great orders and under still fewer classes. As showing how few the higher groups are in number, and how widely they are spread throughout the world, the fact is striking that the discovery of Australia has not added an insect belonging to a new class, and that in the vegetable kingdom, as I learn from Dr. Hooker, it has added only two or three families of small size.

Some young animals spend hours running, leaping, boxing, and wrestling, while others seem to have mush less fun. Could it be a case of mind over metabolism? I'll never forget my first look at a koala brain. I was spending a sabbatical year in Australia and at the time was visiting a study site northwest of Melbourne, where colleagues Tony Lee, Kath Handasyde, and Roger Martin had radio-collared several koalas. When one of the animals died, my biologist friends invited me to attend the necropsy. As the veterinarian lifted off the top of the koala's skull, I was amazed to see that the brain did not fill the space inside. The smooth cerebral hemisphereseach about as large and thick as the peel from a quarter of an orangewere so small that they did not meet at the midline, and when the veterinarian removed the brain and placed it on the table, the feeble hemispheres flopped apart, revealing the midbrain.

Radio National on Saturday 12/12/98 Reintroducing native marsupials Summary: A look at the Return to Dryandra Project, which aims to reintroduce some of western Australia's rare marsupials back into the wild. Included are the boodie, the mala, the banded hair wallaby and the western barred bandicoot, all of which have declinded in recent decades due to lose of native habitat and pressure from feral pests such as foxes and cats. In this report we go out at night and trap the marsupials, to check their condition and numbers. Details or Transcript: An ambitious project to return endangered species to their former habitats has received a good report card for its first nine months of operation. The Return to Dryandra Project is an initiative of CALM, the WA Department of Conservation and Land Management. In autumn this year four groups of endangered mammals were released into their new home into the Dryandra State Forest, 150 kms south west of Perth. The animals are housed in a 20 hectare enclosure surrounded by a 2metre high electrified fence. This is the first time a mammal breeding program has been attempted on this scale. Whereas Dr John Wamsley builds fences to keep feral animals out, the Dryandra fence is there to keep breeding animals in. And eventually, they'll all be released back into the wild. The boodie, the mala, the banded hair wallaby and the western barred bandicoot were brought as far as the Tanami Desert in the NT and islands off the coast of WA. The boodie and the mala are cute furry wallabies that grow to about 20 centimetres. The mala has long ears like the European hare and the boodie has strong barwing claws. It also makes a funny farting sound as it hops along which adds to its appeal. I visited Dryandra during the first trapping program following the animals release into the enclosure. On a chilly winter's night we left the warm fire in our cottage to find out how the mala were adjusting to their new home.

Podcasts Print Email to a friend Kangaroo genome project stays in Australia Edmund Poliness ABC Science Online Friday, 2 April 2004 The kangaroo genome, specifically the genome of the tammar wallaby pictured here, will be one of two marsupial genomes sequenced worldwide (Image: Matthew Wakefield, ANU) A project to sequence the genome of Australia's iconic marsupial, the kangaroo, will remain down-under thanks to a last minute funding deal. The Victorian state government stepped in with extra funding this week, which together with funds from the U.S., would keep the project in Australia. This means there are now two projects worldwide to sequence marsupial genomes: a U.S. project to sequence the genome of a South American opossum, and the kangaroo project. Professor Jenny Graves, a geneticist at the Australian National University in Canberra with the Kangaroo Genome Project , said the last-minute reprieve was "wonderful". "I'm so delighted I can hardly talk," Graves told ABC Science Online just before flying to Berlin for next week's Human Genome Meeting "It's really a wonderful thrill and relief to get the funding and I think it's going to be fantastic for Australia. We'll be mapping a big genome, joining the big boys and doing it ourselves."
