Species had introduced to Australia by human since 1788. When a foreign species had successfully out-compete native organisms for food and habitat‚ it may survive and reproduce. However this species can become invasive when there is an excessive increase of population which can cause enormous damage to the ecosystem. The impacts of the foreign species could be immense‚ insidious and irreversible. In Australia‚ invasive species have been recognized one of the most serious threats to biodiversity

We should take a precautionary approach and restrict the importation of non-native species there is the risk that some of these species can become invasive. There are multiple instances where a species was introduced to its non-native range for recreational purposes and eventually ended up becoming invasive. The feral pigs in Hawaii were intentionally introduced by Polynesian explorers. When Polynesians returned to Hawaii‚ the settlers had something to hunt and eat. Since the pigs’ arrival‚ they

not all‚ of the species‚ including some unattractive ones like snail darters. As mentioned in the book‚ we are now mostly focused on protecting “flagship” species‚ the species that look attractive to us as human beings. When we are amazed at the aesthetic value of those megafaunas like tigers and pandas‚ we are constantly forgetting the values of small animals like snail darters and many other pants. However‚ there are several reasons that we should protect those “unattractive species “too. The author

Saving Endangered Languages- Saving Our Diversity Oliver Wendell Holmes said “Language is the blood of the soul into which thoughts run and out of which they grow.” It implies all the languages in this planet play an important role in formation of diversity and cultural identity. Starting with simple grunts and moans‚ for a thousand years‚ the human species has developed a sophisticated language of gestures combined with spoken language. Today‚ along with many advantages that globalization has

Millions of species inhabit Earth. How do scientists make sense of them all? First‚ scientists study the similarities and differences between organisms. The scientists study characteristics including obvious physical traits‚ such as hair or leaves‚ and molecular traits‚ such as DNA sequences. Then‚ scientists use the information to classify species into meaningful groups. The groups may also reveal which species are related and how they fit along the evolutionary tree. Scientists who specialize in

This report is based on the study of ‘Species Diversity and Ecosystem Stability’ of the New Amsterdam Secondary School’s Eastern Field. This study was carried out by yours truly‚ Cynthia Rutherford‚ from the 26th January‚ 2011 to 5th February‚ 2011. Even though the study was done over a short period of time‚ I do hope that it will be lots of benefit to you the readers and edify you of our environment. Thank you.

idea of bringing back a species from extinction throughout his essay. With examples such as the Pyrenean ibex‚ mammoths‚ passenger pigeons‚ and gastric brooding frogs‚ he discusses how technology and science have advanced to the point that de-extinction is close to being a reality. Zimmer then shifts to the benefits and problems that could arise if we are able to revive an extinct species. As a result‚ Zimmer raises the question that should we bring back an extinct species just because we can? Even

Invasive Species have been described as an organism which is not native‚ and causes negative effects on the ecosystem‚ and to the health of humans. These organisms can be Fauna‚ Flora (Flora and Fauna refer to plant and wildlife‚ respectively)‚ a fungus or a bacterium. However‚ not all introduced species are invasive‚ but invasive Fauna and Flora‚ have been said to be the 2nd greatest threat to biodiversity post habitat loss. In his book‚ Invasive Species in a Changing World‚ Richard J. Hobbs (2013)

organism from a mixture of two unknown bacterial species. In order to accomplish this‚ I first plated my unknown mixture on Tryptic Soy Agar (TSA)‚ Columbia Naladixic Acid (CNA)‚ and MacConkey’s Agar (MAC) plates. After 48 hours of incubation‚ it was unclear that two different bacterial colonies had grown on my TSA plate. Only one type of colony was evident. However‚ it was apparent that I had successfully isolated two different bacterial species by examining my MAC and CNA plates. Only one type
