Why Is Australia's Unique Species

In Tasmania this species is fully protected and the population has been increasing slowly. However, the populations on mainland Australia are so fragmented and small that they may be too small to survive. This species’ recovery in Australia depends on a nationally coordinated approach, with habitat loss, predator control and captive breeding projects all needing to be

The cane toads in Australia has become a national difficulty. The Australian government has been providing funds to help with catching and destroying these pests. Scientists have not been able to find any kind of way to biologically control these toads. According to the Australian Government, “Cane toads have an impact on Australian Government controlled lands, including Kakadu National Park, several World Heritage Areas and Indigenous Protected Areas”. The Australian government has written a policy on cane toads, has started a cane toad advisory group, funded research on controlling and collecting the toads, funded research on the impact of the toads on the Australian habitats and economy, and has educated the public about the toads and how to deal with them. In the future, the government plans to continue to do these same things as eradicating the toads does not seem feasible. All of these efforts are being made to at least reduce the threats to humans and native species in

Propose reasons for the evolution, survival and extinction of species, with reference to Australian examples.

An ecosystem contain biological communities and abiotic factors that interact with each other. However, Introduced pest species in Australia have always been a major issue due to the unique ecosystems that have developed, undisturbed over millions of years, due to Australia's geographical isolation. This is especially evident in the introduction the European red fox in Australia, which has prompt negative changes to the population of the Long-nosed Bandicoot due to the predation by these foxes in the Field of mars and around Australia. The disruption the fox foxes have on the Long-nosed bandicoot can also result in sever cascading effects on the rest of the ecosystem, including abiotic factors like the soil and biotic factors like other native flora and fauna

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.

Australia have many animals that comes in all shapes, sizes, and colors. They all have different ways of adapting to the environment. In Australia, they have more than 378 mammal species. Some stay in trees and some stay on land.

One of the most striking dividing lines between realms is the Wallace Line between Australia and Asia. Because Australia is isolated from the Asian land mass its biodiversity is rich with different species and ecosystems. However, due to trade and human transport methods the highly adaptable and dispersive Aedes albopictus (typically native to Asia) has been located in the Torres Strait (between Papua New Guinea and Australia) with invasion to mainland Australia imminent. This r-strategist has adapted to different environments to promote egg fecundity and viability enabling it to spread further as well as being epidemiologically important threatening global health. This report aims to provide an insight into the species and aims to assess the current damage caused by the invasive Asian Tiger Mosquito (Aedes albopictus) in the Torres Strait.

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

a) Discuss current research into the evolutionary relationships between extinct species, including megafauna and extant Australian species.

Australia is a nation without limits scene, society and more rooted archaic rich economies in the world. Australia is the sixth largest country in area and is the main country to represent an entire land mass. A wonderful native habitat caliber of different qualities and extraordinary life, Australia is a destination for travelers from all over the world and 10 percent of biodiversity in the world and an impressive number of local plants and creatures he n ' There is no other place on earth. Rainforest in the north to the red deserts of the interior, the snowfields of the Australian Antarctic Territory in the southeast, is a vast region and changed. Australia is home to one of the most experienced companies in the world living with indigenous

The impact they have in these national parks are rather positive or negative, curtain creatures/animals such as Cane Toads and Feral Pigs have impacted nature in a negative way. When asked Tom Cannavan (ODE Teacher) about what feral animal in your opinion has a major threat in the Lake Argyle environment, he relied with, “Cane Toads are the main species that are having a major impact on the Argyle environment, as they have cautioned many little insects and animals from their presence through Australia.” Cane toads are native to Central and South America, Cane Toads were first introduced to Australia in 1935 as there was approximately 3000 that were released into Northern Queensland. They were released as a mean of controlling the introduced French Cane Beetle and the Greyback Cane Beetle, by controlling, meaning by reducing the population of these introduced species. Cane Toads pose a threat to wildlife when eaten, because they release a toxin (bufotoxin) from across their backs. This toxin is present in both the adults and tadpoles, meaning Cane Toads may negatively impact a wide range

An example of an invasive species is “Cane Toad.” The cane toad was supposed to get rid of sugar cane pest, but then it came a pest. It only has a few predators outside from where it lives.But when animals try to eat it a discharge of poison goes on it’s skin and the predator gets poisoned and dies in a few minutes.Also it has been released into out of zoos on purpose.The cane toad used to live in South America and mainland middle of America, now it has been moved to Oceania and the Caribbean also North Australia.What people do is they eat toad and make soup of their eggs but this ends up killing them.

The 5 themes of geography are location, place: human characteristics and physical characteristics, human environmental interaction, movement and region. The country this assignment will be done on is Australia. This country is the 6th largest country in the world. Some things i already know about Australia is that sometimes people might say "oh wow she/he has quite an Australian accent. Witch they do have, they speck English but with an accent. Also one more thing i know is that the Great Barrier reef in located on the south-eastern side of Australia.

Known in the scientific community as Bufo marinus, cane toads were introduced to Australia in the mid-1900’s t rate from their native home of South America. Sugarcane crops were at risk of destruction from the infestation of beetles, and these species were brought in to help counter the negative effect that the beetles were having on farms. These amphibians have the ability to grow up to 4.4 pounds, and were soon doing more harm than good. Not only were the cane toads eating the beetles that they were meant to, but they also started including native insect-eaters in their diets (Roach). This new addition to their food source helped the toads to thrive and expand their habitat region.

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
