Rabbits in Australia Introduction Coevolution is a natural phenomenon that has affected all habitats throughout the world. In general, it encompasses the interactions among different species within a general population and the adaptations each species makes to survive in such a diverse environment. The mere presence of all species that are currently in existence is proof that those species have adapted over thousands and millions of years in such a way that allows them to survive and reproduce. Through millions of years of evolution, well-balanced habitats have co-evolved to provide for the wide variety of species and their needs. Trees have adapted to weeds, weeds have adapted to the predation from herbivores, and so on up the food chain. Similar scenarios are seen throughout the world. Through the process of natural selection, specific species or broad species families will go extinct. However, these occurrences have largely been due to the natural flow and evolution of time. It wasn’t until recently that dominant species, such as humans, have taken the course of nature into their own hands. Throughout history, humans have had an increasingly profound impact on the areas in which they inhabit. Human population has increased in a slow yet exponential pattern since their evolution. These growing populations, along with species evolution have directed humans such that they have domesticated themselves and the things around them in ways that are both functionally and aesthetically pleasing. Plant species were transformed into useful crops, wild animals were converted to willing (and sometimes not so willing) companions, animals were hunted for food and for sport, and man's surroundings were modified as were seen fit. However, beauty is in the eye of the beholder. As the environment has become modified, harmful consequences have resulted causing many of the natural coevolutionary processes to fall out of balance. 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. History of rabbit origin in Australia It all started in 1859. Australia was slowly becoming populated with European pioneers who sought the newness of the great, unsettled continent. However, there were a few things from home from which they just couldn’t part.
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...
In conclusion, I think that the U.S had both economic and democratic purposes for entering World War 1. One sole reason for entering is not a valid enough reason, nor was there only one. Democracy across the world was jeopardized and the U.S also saw that it could eventually make a profit from it. Overall, the U.S’s involvement played a key part in the war. I believe that entering was a good choice especially because it ultimately helped the Allies
A different scenario takes place when an alien species is transported to a new area. Although direct competition with similar species is still a problem, the new kid in the block may have no natural pests and diseases. Thus, large stands of monocultures can occur. It is generally accepted that one plant species will support 10 species of animals. If one species takes over 99% of a given habitat dozens if not hundreds of species are lost from that area and some populations are stressed enough that extinction is possible.
Long-term survival of a species depends on its ability to adapt to changing environmental conditions (Murphy, 1994). Genetic diversity within a species, which has taken 3.5 billion years to evolve, makes adaptations to these changing environments possible. Unfortunately, the rate of extinction of genetically diverse organisms is rapidly increasing, thus reducing this needed biodiversity, largely due to the human impacts of development and expansion. What was an average of one extinction per year before is now one extinction per hour and extinct species numbers are expected to reach approximately one million by the year 2000 (WWW site, Bio 65). As a result governmental and societal action must be taken immediately!
War is complicated and messy, this is especially true for WW1. WW1 seems to have been forgotten, not as talked about compared to the sequel, and this is for a reason. in WW2 intentions are clear, countries have clear motives, there is a clear good and bad, and the historical relevance is obvious. In WW1 why the countries even joined the war is a heavily disputed question. The most common reason cited as to why we joined the war is the sinking of the lusitania, in my opinion the answer is more complicated like the war if self. There were many plausible causes for america joining the war the lusitania and sussex, unrestricted submarine warfare, american companies supporting the allies worried that they wouldn’t win, the fact that britain had the same language and similar culture to the united states, and the zimmerman message. However in my opinion the reason america joined WW1 was because the american financial support of the allies.
A Light In the Attic is a children's book of approximately 35 poems that encourage children to make light of difficult subjects. Some of the poem titles comprise of “How Not to Have to Dry the Dishes,” “Monsters I’ve Met,” “Messy Room,” and “Somebody Has to.” There are many topics discussed in the book. The topics can be as heavy as death or subjects such as doing chores. Other issues Silverstein discusses is life, getting older, not getting what you want, how to approach things and more. Juveniles reflect as plentiful as everyone else when it comes to serious topics and Silverstein acknowledges that. He tries to add humor to these topics and incorporates it into his poems. In A Light In the Attic, Silverstein added some silly aspects to things like chores. Consequently,
The safety of meat and poultry is a topic that has been debated for a number of years. Contamination is especially a concern when raising cattle and turkey for food. A recent article from DiGregorio (2013) highlights a debate over the safety of ground turkey sold in U.S. supermarkets. According to the Consumer’s Union in the article, a large percentage of ground turkey was found to be contaminated with fecal-associated bacteria, such as Escherichia coli, Enterococcus, along with other types of pathogens, such as Salmonella and methicillin-resistant Staphylococcus aureus (MRSA) (DiGregorio 2013).
To reiterate, fear links to constant fear of conformity, secretive behavior, and obsession with religious teachings that protect the conservative views of the society of Waknuk. What I have learned in The Chrysalids by John Wyndham is that fears affect perception, your perception changes according to your psychological state and it affects your behavior as well. People reflect regarding their fears all the time and as they feel that they will come upon them, they start becoming apprehensive. When an individual is afraid of something, they may experience unusual judgment that they would have never made before which all the main events that occur in The Chrysalids relate. The main thing I learned was the two powerful emotions that result our actions is fear and love.
Should America have gone to war? In August, 1914, Germany and Russia went to war after the assassination of Archduke Ferdinand of Austria and Hungary. Great Britain and France allied with Russia but America did not take part in the war. America’s goal was to stay neutral. But, one day in 1917, it was announced that we were going to war against Germany. Why should we go to war? What supports our reason for going to war? The facts presented will show why America should have joined World War 1.
Yet there are good reasons to attempt to do so. Meteorologists have warned us that pollution linked to the tremendous and growing resource use of the immense and expanding human population will lead to a greater frequency of extreme weather events such as hurricanes and tornadoes, as well as a rise in global temperature; the last decade would seem to support such a suggestion. Biologists have gloomily predicted that many of the Earth's species will be exterminated within the next century, as a direct result of the human domination of the landscape. Social scientists are well aware of the putatively causal link between overcrowding and social conflict, violence and war, and we already have no shortage of these three evils. Even now humans have seriously impacted most ecosystems on Earth, and use more than half of the fresh water accessible for consumption. It is a fundamental truth that on a planet with finite resources, unrestrained growth is an impossible practice to sustain; all of the signals woul...
Milk is one of the most nutritionally complete natural foods. It adds high quality proteins, fats, minerals and vitamins to our diet. However, when this milk is handled improperly the bacteria present in milk can multiply and make the raw milk potentially dangerous. Our environment is full of microorganisms that can enter milk during the milking process when the equipment used for milking, transportation and storing milk are not properly cleaned.
The introduction of a new or exotic species, into a new ecosystem has been long known to threaten the integrity and biodiversity of that ecosystem worldwide. The European wild rabbit is an excellent model to demonstrate the range of complex effects that an introduced mammalian species may exert on ecosystems into which it has been introduced.
The ending of species such as weeds that are used by animals as shelter and/or food sources.
The purpose of obtaining this knowledge is to show a direct relationship between the processing conditions of meat products and their bacterial allotment. If the sources of the meat, or meats being processed, are exposed to unsanitary conditions, then there will be a higher level of bacterial infection amongst the products. As found by McGinnis and Gill in 2004, once...
Food is a product that is rich with nutrient and can be contaminated with exposed to major source such as water, air, dust, sewage, insects and rodent (Oi Nee and Norrakiah, 2011). As a food handler they need to handle the changes in preparation techniques and food production because the fact remains whereby food is the source for microorganism which can cause illness (Oi Nee and Norrakiah, 2011).
