...Both the author and the lecturer speak about the zebra mussel species and their migration to some parts of North America; but in terms of how it has affected their new habitat, the reading passage and the listening are at odds with each other. The author proposes that the zebra mussel has had a negative impact on their new habitat, according to an unstoppable invasion and aggressive population. The speaker, however, refutes the author's point of view by presenting other evidence. As the author states, the zebra mussel's migration has been unstoppable by virtue of human activity. In fact, the zebra mussels attach to the bottom of ships that cross the man-made canals and waterways, and they can survive in the "ballast water" and reach North America. On the other hand, the speaker argues that ships can empty their ballast water and refill it with ocean water, which is salty and lethal for the zebra mussel resulting in stopping their migration....

...The reading passage explains about how the zebra mussel population dominates other fresh water aquatic fishes and also how inexorable the mussel species. However, the lecturer refutes this and he uses other information and he says that the mussels can easily be controlled and the passage is exaggerating about the mussel. According to the professor the mussels were wouldn’t controlled because of lack of proper knowledge to deal with them. But now that’s not the case anymore. He explains that how zebra mussel population can be desisted across the European canal. The passage says that human transportation like ships are primary sources of invasion of mussels in the North American waters. As the ship uses Ballast water to balance the ship, the...

...1. Give 3 examples of endemic and 3 examples of an invasive species. Endemic species invasive species Blue fin tuna snakehead fish Asian elephant stink bugs Sperm whale Zebra mussels 2. Pick one species (endemic or invasive) and discuss its role in the environment. I choose an endemic species the Asian elephant. The elephants importance is that they assist with logging forests, carry heavy material, and assist as transportation. They have the ability to walk in areas where machines are unable to go, their vital role in an ecosystem is they modify the habitat that affects all other plants and animals. They provide water for other animals by digging water holes in the dry seasons (they can easily locate water underground). They make paths in the forest by pushing brush and pulling down trees and also disperse seeds of fruits by depositing them in their dung. 3. What economic impact does it have on human society? Endangerment affecting humans is due to the destruction of habitats there’s not enough food in the small forest for the elephants so they go and look for other food sources which are crops in nearby fields. Attempts were made to locate these animals but because of change in habitats they’ve raided villages and destroyed homes and crops not only do they pose a danger to human society we also pose a danger to...

...Lake Erie Ecosystem Structure, Function, and Change Denise McSalters SCI 256 November 13. 2013 University of Phoenix Lake Erie Ecosystem Structure, Function, and Change Carved out by glaciers during the last ice age the Great Lakes contain 20% of the earth’s fresh water. The lakes provide the majority of the basin’s human population with drinking water, commerce and recreation. Lake Erie is the smallest of the Great Lakes, relatively shallow, and is exposed to prevailing winds. Lake Erie ecosystem supports a diverse group of aquatic and land-dwelling organisms who use the ecosystem during important life stages. The lake support high production of both residential and migratory species and is a center for regional biodiversity. (US Department of the Interior; US Geological Survey, 2013) Because Lake Erie is exposed to prevailing winds, it is particularly susceptible to intense wave actions and wind-generated changes in the lake level. The “seiches” or changes in the lake tides interchangeably flood and drain the coastal wetlands systems. The costal wetland systems encompass southeastern Michigan, northwest Ohio and southern Ontario. The Watershed is almost completely urban or agricultural. The major urban cities are Toledo, Detroit, Cleveland, and Buffalo. (US Environmental Protection Agency, 2013) The most obvious forcer of Lake Erie ecosystem change was due to the input of excessive amounts of phosphorus from mainly agriculture and water treatment plants. At...

...From figure 1, we can see that the flow of invasive alien species is between developed countries. A possible reason for this may be that developed countries tend to have more marine trade between other developed countries. This means that species around the world can be easily transported between countries, and thus leading to invasive species in many ecosystems. There are number of ways that species can be transported around the world, as these are marine species, one likely method they can be transportation through ships. Animals such as mussels are able to cling to the hulls of ships and thus they are easily transported to different areas within the world and away from their native habitat. Another possible way marine species can be transported around the world would be through ballast water from ships. Marine animals can also be introduced in to native ecosystems deliberately due to scientific reasons. A reason why invasive may be not shown in the figure between poorest countries might be due the fact that poorer countries have minimal marine trade links between countries thus restricting the movement of invasive species. There is significant damage that can occur from non-native species when they intrude ecosystems. This is because invasive alien species are well adapted to live in many habitats and therefore they can easily spread in to many ecosystems. As they are well adapted to live in habitats they are also able to reproduce in habitats that are not originally theirs...

...can be curbed by cold temperatures (mild winter) which renders them inactive (Emerton, 2008). They (killer bees) attack violently and usually entail many stings, which, when accumulated, are fatal to people and animals. The thriving population of lionfish in Atlantic Ocean affects us by reducing the resources available for commercial fishing industry. Lionfish feed on small crustaceans, coral reefs, and young fish (inclusive of the young of vital commercial fish). Lionfish’s venomous spines are very painful to the human body. Natural predators and groupers are set to remedy this hazard since the available potential predators cannot alleviate the lionfish available in the Ocean. Spearing and eating them is also remedying the situation. Zebra mussels are invasive species in the Great Lakes. They were inadvertently brought into Lake St. Clair, after which they spread all through the Great Lakes. They caused harsh problems at municipal water supplies, power plants, clogging intake screens, cooling systems, and pipes. They have also alleviated, nearly, the ecosystem’s clam population.

...In Anna Smith’s Letters to a Young Artist and Chaim Potok’s “Zebra”, there is one main question - do artist need knowledge and empathy to create great art? Art can be anything from football to music, or from dancing to painting. These two stories show how when empathy and knowledge are provided for a person, their art comes out greater than before. Knowledge is the information acquired by someone through education or experience. Most people think that knowledge is knowing facts, but really knowledge is so much more. In Letters to a Young Artist, the author states that the “...fundamental to becoming an artist is understanding the position of an artist…” which leads “...to develop the eye, the ear, [and] the heart.” (Smith).

..."Some healthy fruits and veggies you can feed your zebra finches are broccoli, corn, spinach, carrots, peas, sweet potatoes, kale, yams; bananas, apples, peaches, apricots, pears, watermelon, and grapes. You can either cut up fruits and veggies into tiny pieces or serve clipped to the cage, for example, a broccoli floret. Make sure all food is fresh and thoroughly wash all raw food before serving to your finches. Finches can also eat hard-boiled eggs (you can remove and crush the egg shells and feed those to your finches for calcium), brown rice, cooked oatmeal, cooked rice and cooked pasta. Don't keep any food out for too long, especially eggs, as they will spoil. Avoid feeding your zebra finches any apple cores, the pits or seeds of any fruits, avocado, chocolate, caffeine, high-salt foods, rhubarb, onions, and mushrooms. Those foods are toxic to zebra finches." Source(s): Zebra Finch FeedZebra finches are seed eaters. They primarily feed on grass seeds. Various variety of millet is their staple food. Zebra finches are typically found in scattered bushes and trees. But they are now adaptable to human surroundings and are loved as pet birds. They need to be provided with proper feed that includes balanced diet and fresh water. Some feeds are described here that are useful for bird.Seeds:Zebra finch feed comprises of a good quality finch seed mix. This should not be the sole diet provided to finches. The seed provided should be well sprouted. If seeds are not sprouted...

...The trends in the results depict that wildebeests spend more time standing or lying down, while zebras tend to spend the majority of their time grazing throughout the day. Since wildebeest and zebras are two different species, each one has its own basics needs that must be met. From the results, it can be inferred that zebras require less food more frequently while wildebeest require more food less frequently. This can be accounted through their digestive physiologies since monogastric animals tend to digest their food more quickly than ruminants do. It is because of their digestive physiology, wildebeests and zebras have relatively different daily activity budgets in order to meet their specie-specific needs, thus supporting the initial hypothesis....

...can extract more nutrients from their food, therefore have to eat less to get as much energy as a hindgut fermenter. (Illinois Edu) “The foregut fermenter herbivores are a lot more efficient as the food is digested on the first pass through the digestive system.” (VetSci, 2011) As seen in figure 1, the wildebeest grazes less than the zebra, however does a lot more of everything else. As said in the hypothesis, the foregut fermenter has a much more effective digestive system and therefore needs to consume less, and use less energy to digest food as there is less to digest and the digestive system is more efficient. Even if the wildebeest were to eat the same amount of food as the zebra, the wildebeest would still get more nutrients out of what it had consumed than the zebra because the food that is consumed is digested on the first pass through the digestive system. As shown in figure 2, the zebra spends most of it’s time grazing, this is because in order to have energy and nutrients in it’s system it need to consume a larger amount of food than the wildebeest. Zebras also migrate about 800 miles more per year than wildebeests, this is because the zebra consumes more food, and therefore suppresses their food resources more frequently. “A...
