Marsupial

The koala (Binomial name: Phascolarctos cinereus) has been referred to as one of the world’s most iconic animal species by the World Wildlife Federation. A koala is a bear like herbivorous mammal that’s in the marsupial category. The name koala is the Aboriginal term for ‘no drink’ as this refers to their diet consisting of eucalypt leaves and little water. Koalas are very sedentary animals only moving if they need to eat and escape. Koalas have spooned shape noses, big fluffy heads, and a body…

In 2012, zoologist Peter Menkhorst conducted a study to investigate the claims that large predatory cats inhabit Victoria. This was done to satisfy the many claims of large cat sightings and reports of the animals attacking and eating livestock. Menkhorst concluded that: “The most parsimonious explanation for many of the reported sightings is that they involve large, feral individuals of the Domestic Cat Felis catus. However, some evidence cannot be dismissed entirely, including preliminary…

As biotechnology continues to advance, a matter that interests both genetic and conservation scientists is the de-extinction of species, or the resurrection of lost species. The idea of Jurassic Park, a 1993 American film where genetic scientists created a wildlife park with cloned dinosaurs, is no longer science fiction. It is becoming an increasingly considered possibility, and with the present-day extinction rate of species higher than ever, scientists have commenced to ponder the prospect of…

rashes, swelling of the lymph nodes and a fatigue, muscle pain and headaches (Ross River Virus Transmission, Infection, and Disease: a Cross-Disciplinary Review, 2001). It is thought that the virus is spread to mosquitos from native mammalian and marsupials like kangaroos and wallabies. During outbreaks of RRV such as the one that took place in 1996 it is also believed that mosquitos may acquire the virus from humans. Many people infected do not experience any symptoms, children are…

like the house sparrows whose size and color changed when this species came in America. Moreover, we also have new type evidence. Distribution to time and space allows us to understand why and how we can find different evidence, by example the marsupial’ fossils, in many continents by looking at the history of life. But, our biggest improvement is to be able to look at species DNA. It helped us to understand more the connections and the variation of species (lecture). Finally, all those evidence…

In the United States today 14% of adults are illiterate, while 21% read below a fifth grade level, at the same time, 19% of the students who graduate high school cannot read. (U.S. Department of Education and the National Institute of Literacy) Meanwhile todays schools do not teach students about the science they will need to know in their daily lives. Such as informing them how to make decisions related to their health, and issues in science they see on the news or read about in the paper. The…

Piedmont in Northern Italy. Odd and confusing I felt, since I could not discern the grounds of such a concrete presence. Imperative is to stress that I mean “concrete” in two senses: the material (the cement of the moulding) in which this particular marsupial was made and hung on the lateral outer wall of the local bar, facing the main square; and its categorical ubiquity. The kangaroo was there and I could fantasize that it has been –from immemorial times- monitoring every movement in this…

around a property is often impractical” Dr. Johnson wrote. The lessons acquired at Middle Island are being applied elsewhere. For example, at Zoos Victoria, a pilot program is underway that pair Maremma dogs with bandicoots, a tiny rodent-like marsupial at risk of extinction in Australia. That said, Abbott cautions that the use of Maremma dogs to protect vulnerable species isn’t easy task. After all, dogs will be dogs. From time to time, they do wander off Middle Island to pursue foxes,…

Just like pores on human skin which absorb elements of the world around us, the holes all over the sponge’s body as essentially pores as well. The function of the holes all over the sponge’s body is to allow water to be absorbed into the sponge’s body. Through the absorption of water, the sponge also absorbs food and oxygen to ensure survival. There is no one set type of symmetry for sponges. Therefore, not all sponges have the same type of symmetry. Sponges can range from asymmetrical to…

Discuss the role of thermoregulation in tetrapods as an adaptation for life on land. [6] Enzymes serve as catalysts for chemical reactions in the body, and they function more efficiently within select temperature ranges. As such, it is advantageous for vertebrates to maintain a body temperature that is consistently within this ideal range. Thermoregulation is the maintenance of this ideal body temperature range. Aquatic habitats are naturally thermoregulatory due to the ability of water to…
