The red kangaroo (Macropus rufus) is the largest surviving marsupial anywhere in the world. The Red Kangaroo occupies the arid and semi-arid centre of the country. The highest population densities of the Red Kangaroo occur in the rangelands of western New South Wales. Red kangaroos are commonly mistaken as the most abundant species of kangaroo‚ but eastern greys actually have a larger population.[18] A large male can be 2 metres (6 ft 7 in) tall and weigh 90 kg (200 lb).[19] The eastern grey kangaroo

Marsupial Migration and Speciation Between New Guinea and Australia along the Torres Strait Abstract The strait of Torres represents a submerged land bridge separating New Guinea and Australia that opens during periods of glaciation. The flow of genes and migrations occurring in this region during these periods are hypothesized to inhibit speciation in regions directly adjacent in the to strait of Torres. A comparison of four species‚ three endemic to New Guinea: Dasyurus spartacus‚ Planigale

Continental drift has helped create the diversity we see present in modern day plants and animals. Through a process of speciation‚ the movement of the continents has had a generous role throughout evolution‚ effecting and distributing flora and fauna. The Earth’s continents were once one‚ a large supercontinent called Pangea that later separated into two smaller ones known as Gondwana and Laurasia. The separation and collision of continents has not only created some of the valleys and mountain ranges

"What’s Going Down in Geology" "What happened to the Big Marsupials of Australia‚ what does that have to do with the simultaneous rise and fall of the Sierra Nevada?" was the question on Thursday‚ in room Science-422. Geology instructor Roger Chambers went on to ask: "What’s your favorite Marsupial?" to break the ice and show how little we‚ the audience‚ actually knew about them. I personally was not aware that Australia was a devastated ecosystem built around them. He‚ like many experts believes

Koala Bears [pic] The koala (Phascolarctos cinereus) is an arboreal herbivorous marsupial native to Australia‚ and the only extant representative of the family Phascolarctidae. The koala is found in coastal regions of eastern and southern Australia‚ from near Adelaide to the southern part of Cape York Peninsula. Populations also extend for considerable distances inland in regions with enough moisture to support suitable woodlands. The koalas of South Australia were largely exterminated during

years ago‚ a monster roamed Australia‚ it’s name‚ Megalania. At this time‚ Australia was full of gigantic animals such as the Procoptodon and the Diprotodon and feeding on these gigantic animals was Megalania. There were other hunters such as the Marsupial Lion‚ one of the best hunters in the world at that time‚ but they were no match for this monster lizard. Today‚ scientists observe other monitor lizards‚ such as the prehistoric lizard’s closest relative‚ the lace monitor‚ and make observations about
