Introduction
• The reintroduction of dingoes to the natural environment has been a highly debated and controversial topic. Dingoes in the south-eastern part of Australia have been controlled via various methods to reduce their impact on the environment and farmer’s livestock. Reintroduction could result in strengthening and repairing ecosystem diversity, however it could also compromise endangered lower end species and deplete farmer livestock.
• There are both positive and negative impacts the reintroduction of dingoes could have on the native flora and fauna of the ecosystem. (Cooke and Soriguer, 2016)
• This essay will discuss the possible advantages of dingo reintroduction and consequences, and aim to highlight the compromise that will

They also pose a risk to decline the threatened species of wild foxes and cats. (Allen and Fleming, 2012)
• The use of dingo controlling techniques have been utilized largely since the 19th century to restrict the spread of dingoes into sheep grazing areas. (Allen and Fleming, 2012)
Paragraph 2
• The reintroduction of top end predators such as dingoes back into the environment, is an important factor for the conservation of biodiversity (GLEN et al., 2007)
• By balancing the lower end of the food chain smaller predators, building the resilience of ecosystems with a more diverse spread of species, dingoes can help restore the biodiversity naturally to damaged ecosystems. (Letnic, Baker and Nesbitt, 2013)
Paragraph 3
• Another proposal for dingo reintroduction is; the regeneration of degraded rangelands, by reduction of dingo prey and feral species. (Newsome et al., 2015)
• A key point for the reintroduction of dingoes to the natural environment is their role in ecological processes such as regulating trophic cascades. The case study shows that the eradication of dingoes and the consequences on the ecosystem. (Letnic, Ritchie and Dickman,
A species in particular that I have researched is the red fox or Vulpes vulpes as it is known in the scientific community. The animal is native to North America, Asia and Europe where they thrive in habitats ranging from temperate deserts to boreal forests, but its range spans the entire globe (Tesky 1995). The red fox is omnivorous which means that it feeds on animals and plants equally, which, creates impacts on both types of populations within its habitat. What makes the red fox invasive is its introduction to Australia and Eastern parts of the United States, as a result of migration of Europeans t...
...rupt native species and ecosystem hence making the restoration of both evolutional and ecological potential almost impossible. Whereas Donlan (2005) concluded that re-wilding North American is the best conservation strategy to the African and Asian threatened megafauna, meanwhile re-wilding will restores the evolutionary and ecological potentials in the process. In my point of view, Pleistocene re-wilding must not be implemented simply because the introduced species might fail to adapt to the new environment. High costs and disease outbreak are another challenge that can’t be ignored.

As a result, their habitat is being destroyed, leaving them with no place to live and to nest their young. They are also being disturbed by human activities near their habitat.

Slowly, the disruption of these delicate balances are taking their toll on the native habitats and transforming small temporary changes into permanent problems. The area of environmental modification that will be emphasized in this paper is the introduction of non-native species to new habitats and the resulting effects on that habitat; specifically, the introduction of the European Rabbit to Australia.

Their findings contributed to a further explanation of the definition of an invasive species. It was concluded that invasive species are detrimental to the environment that they are invading. Jackson (2015) mentioned that negative relationships among invaders are a particular concern since it is possible that both of the invasive species would need to be controlled in order for an area to rebound after invasion. Hoopes et al. (2013) concluded that native species on island refuges are more likely to be come extinct during an invasion compared to those of mainland refuges. These results also help to confirm the importance of understanding invasive species from a conservation point of view since invasive species are a major threat to native populations in their
In spite of the overwhelming amount of negative speculation, the practice of de-extinction might potentially produce some positive ramifications. According to Stewart Brand, a writer for National Geographic, humans should bring back extinct species “to preserve biodiversity, to restore diminished ecosystems...and to undo harm that humans have caused in the past.” If humans were to tamper with nature and bring back an extinct animal, desolate ecosystems which previously thrived, such as deserted islands, could be partially restored through their
Thousands of years ago, hunting may have been the cause of the extinction of the North American large land mammals. “Moving up into the 1940’s and 50’s some of today’s most prominent game animals were almost non-existent.”(Kerry G) Over-hunting will directly cause the decline in the particular animal’s species. This will effect everything around it, for example ...
People today use hunting as a sport. Of course, not everyone agrees with hunting, but those who like to hunt justify their actions by saying that they are helping with the overpopulation of animals, like deer. The truth is that we are affecting the population of animals. Animal overpopulation can be due to the loss of an animal’s natural predator. Predators are extremely important in an ecosystem, and they are nature’s way of controlling the animal population. In William Stolzenburg’s book, Where the Wild Things Were: Life, Death, and Ecological Wreckage in a Land of Vanishing Predators, he addresses the importance of predators in an ecosystem. He discusses an experiment done by a zoologist named Robert T. Paine. Paine decided to do an experiment to see what happens when one disrupts an ecosystem. He conducted his experiment on rocks along the shore in which a species of starfish was the top predator. Paine’s experiment consisted of grabbing the starfish off the rocks and throwing them into the ocean. His results showed that one single species has a tremendous effect on its ecosystem. After getting rid of the top predator, about half of the species that

The. In 1995, the number had been reduced to around 64 million. Within 20 years, in short, the duck population was reduced by almost one third, showing. the drastic toll hunting is taking on our wildlife. If we assume that other species have been reduced in number at approximately the same rate in recent years, then what are the larger implications for our ecological balance?

One of the big causes of extinction or the endangerment of species is foreign species entering a habitat. This species that are not native to the land can disrupt the food web in that community. These species take control of the food web and endanger some of the other species. The native species become endangered and over the course of many years they either adapt to their new way or life, the foreign predator leaves or is killed off due to the different environment, or the species is killed off and becomes extinct. Organizations like the “World Wild Li...
