home. Shipping vessels coming from other waters carry many unwanted guests, known as invasive species, to make home in our waters in the United States. Invasive species hiding in the ballast of ships entering the Great Lakes damage the Great Lakes’ ecosystem. Invasive species enter the Great Lakes in the ballasts of shipping vessels. Shipping vessels are large ships, such as a freighter, that contains cargo such as iron, grain, steel, and consumer products that are usually imported from other…

of new 28 organisms due to mutation can cause disturbance of exist- 29 ing ecosystems. On the other hand, even if sickle cell ane- 30 mia acts as a harmful mutation in most environments, it 31 can act as a beneficial mutant by virtue of the heterozy- 32 gote advantage and may promote human survival in 33 malaria-infested regions. Like these examples, mutation 34 has both positive and negative effects. 35 Existing ecosystems may be also disturbed by the 36 influx of new alien species. For…

With the accidental introduction of exotic pathogens into areas they previously did not exist, the forest ecosystems of the world are being profoundly impacted and altered (Tomback and Resler 2007). The introduction of diseases, especially fungal diseases, have in some cases, either entirely eliminated or greatly diminished key tree species and as a result altered entire forest ecosystems (Tomback and Resler 2007). One such fungal disease is white pine blister rust, Cronartium ribicola. White…

Water Cycle works? The water cycle is a process in which Earth’s water never stops moving by three steps evaporation, condensation and precipitation. Water is if not the most one of the most important components of life. Water defines how most ecosystems are. The water cycle is also connected by several ways to every other system in Earth. What is the water cycle? Water in Earth is always in movement, but how does it move. The water cycle also known as the hydrological cycle is the way in the…

rainwater is lower. This would make rain extremely acidic. There are two main pollutants that are responsible for acid rain and they are sulfur dioxide and nitrogen oxide. Because of this acid rain there are many different ways that it affects ecosystem…

Ecological succession is predictable change over time in an ecosystem. There are two kinds of ecological succession, and those are primary and secondary succession. Both of these can affect a community is various ways. In the Lion King, secondary succession, which is a type of ecological succession that is a result of a disturbance which changes an existing community without removing the soil, shows up and it greatly, affects the community. When Scar becomes king, the land goes into a great…

environment, ecosystems and the well-being of humans. Pollution is the introduction of any unnatural substances into the natural environment such as pesticides, plastics, and oil spills. Although Canada has made significant improvements, there are still water pollution issues that need to be solved and addressed. Pesticides are one of the many pollutants that enter water bodies that impose a threat to humans and ecosystems. The toxicants from pesticides have a significant effect on the…

done to the ozone, has led to extended warm or cool periods that ultimately affects the ability of these organisms to adapt to their natural habitats. This contributes to sudden and unwanted death. There are many processes that ecosystems…

Media article 1 (Coal seam gas exploration and extraction): Explain history of your topic – Coal seam gas (CSG) exploration and extraction is an aggressive form of mining. The coal seam gas mining industry began in 1976 in the Bowen Basin, Queensland. Commercial production began in Queensland in 1996. The first standalone commercial production of CSG in Australia commenced in December 1996 at the Dawson Valley project. Coal seam gas is used in the same way as any other form of gas for cooking…

various sizes that include small, shallow tundra ponds, and larger, deeper water bodies. Climate change is predicted to affect the structure and function of freshwater ecosystems including species richness, biodiversity, and range as the chemical and physical systems change. This can trigger a cascading effect effecting food web and ecosystem productivity. There is a marked northward decrease in the diversity of algae and aquatic mosses and fish species; yet they remain an important resource. It…
