Essay about Placental Ruminants and Herbivorous Marsupials of Australia

Thirteen bird species and ninety-six species of reptiles and frogs are found across the Flinders semi-arid biome. The mammal species that live there are yellow-footed rock-wallabies, emus, flinders ranges worm-lizard and kangaroos. There are animals in my biome that are used by humans. For example, Kangaroos and Emus are farmed for their meat. Restaurants serve kangaroo and emu steaks on their menus. Supermarkets have kangaroo meat for sale. Kangaroo meet is also used as pet food for cats and

The aboriginal Australians have survived thousands of years on what they call a hunter gather diet. The diet consists of emu, lizards, moths, kangaroo and snakes as well as berries, roots and honey which are referred as ‘bush tucker’. Seafood also had a big part in aboriginal culture, which most of the sea life was caught with spears and hooks made from branches, rocks etc. When the British settlers came in 1770 they unfortunately didn’t like or understand the aboriginal diet. So in response to this they decided to make a more familiar European diet. Sheep, cattle and other familiar European animals were introduced throughout Australia and familiar crops were planted as well. Flour was used to make bread and damper (thicker bread which was

All mammals have hair and mammary glands which is what separates the group from others. However most modern mammals are also distinguished by a single dentary bone, the mandible, and most have two or more types of teeth. Also, most mammals have sweat glands.

Arriving in Australia in 2010, at the Brisbane Airport, I looked forward to owning a Koala as a pet, and kangaroos jumping around in my front yard. I was sorely disappointed when I found out that this was not the case. A few months later I was faced with reality.

Meet this amazing creature the Toolache Wallaby, better known as the Mocropus Greyi. This wallaby looks like it's related to a kangaroo. The wallaby stands on two legs, hopes like a kangaroo, and has a black muzzle, this amazing animal is sadly extinct, thanks Europeian wolf, (IUCN red list) We would have a vast variety of wallabys. Once, this animal had a very minimal danger but then the Europeans introduced a new species to this land of Australia and many other locations(Australian government department of the environment energy). This animal was introduced in 1845. This wallabys diet consists of birds, small rodents, and small reptile(IUNC red list). The Toolache Wallaby's habitat is made

Among the many different marsupials in the world, there is one that stands out and is recognized, not only for its looks, but also for the hardships that it deals with in being a koala. The koala originated in Australia, and was discovered by trappers around the time of 1798. Many rare and exotic animals have been found in Australia, because of its remoteness and isolation from most of the civilized world. Australia has been described as a huge ark, a giant lifeboat, cut off from contact with the rest of the world and carrying with it a group of unique creatures (Serventy 1975). The creatures that inhabit Australia are made up of many different classifications of animal groups that have found themselves all living

As evolution evolved, so did the digestive systems of various organisms. From earth worms to the fetal pig, the digestive systems have changed due to genetic and environmental factors for survival. The six organisms that we dissected in this course are the following: the earthworm, the clam, the crawfish, the starfish, the perch, and the fetal pig. We will discuss each organism’s digestive system associated with their eating habits, discuss the changes in the digestive systems from the more primitive to the more advanced, and discuss how these advanced characteristics improved the efficiency of the organism’s digestive system.

The Tree Kangaroo but the scientific name of it, is Dendrolagus. This is located at rain forests of Australia, West Papua, and Papua New Guinea. Fewer than 250 Tree Kangaroos are left in the world. These animals are herbivores they eat leaves and fruit for their diet. Owls, eagles and pythons are all predators of the Tree Kangaroo. This animal's offspring is 44 days long. When they are born they are called Joeys. They stay in their mother's pouch so they can nurse in their until they are old enough to come out.

All Marsupials originated from South America. When Pangea started to split most marsupials fled to Australia, because South America and Australia were connected during Pangea. Now Marsupials are being hunted for their fur. Also non-native animals have been ruining their ecosystem. Australia has been trying to pass laws to save marsupials, but all animals face the fear of being poached.

development of taphonomic tests should be guided by three premises: 1) taphonomic measures used to

Vestigial structures provide clues about a species’ evolutionary past by helping us to be able to identify species that share a similar common ancestor. A popular example of this with a human is the appendix. To modern humans, the appendix has virtually no use and can be removed with no consequence or ill effect. However, to some of today’s species, such as the rabbit, the appendix is crucial to their survival, as it helps them to more easily digest leaves and other vegetative matter. This has allowed scientists to hypothesize that this means that our distant ancestor’s diet was primarily herbivorous. This in turn as also allowed them to create a second hypothesis that early humans having more meat in their diet is what aided our brains in evolving into the complex and intricate organs that they are today. When we were no longer solely dependent on vegetative matter, the appendix was no longer necessary to our survival, and, as such, became a vestigial structure.

Comparision between prototheria, metatheria and eutheria – Prototheria Metatheria Eutheria *Distributed in Australia, *Exhibit discontinuous distribution *Distributed world- wide Tasmania and New Guinea (Australia, South America) *Most primitive mammals *More advanced than prototherians *Highly evolved mammals . .. . with advanced organization.

Introduction: The following animals I am comparing have evolved to digest nutrients efficiently. The comparisons will determine who is more efficient at digesting different nutrients.

The livestock of man has been distributed throughout the world. Horses, cattle, sheep, pigs and goats can be found on every continent of the planet, with the exception of Antarctica. These common animals supply man with food, materials, and transportation. For thousands of years men have bred these animals for specific purposes. Horses have been bred for work and racing. Cattle have been selectively bred to supply more meat and live in different conditions. Higher quality wool and meat production is the goal of sheep breeders. Yet all of these selectively bred, finely tuned animals require many hours of tending to. Also, they are limited to living in relatively hospitable environments. The

The optimal dietary inclusion level of digestible carbohydrates has been established between a recommended 20% maximum for carnivorous species and 40% for hot water omnivorous species (Wilson, 1994), although the observed responses for different types and levels of carbohydrates are varied (McMeniman, 2003; Mohapatra et al., 2003).
