A tale of modern whales: Divergence and radiation of Neoceti during the Oligocene period likely driven by environmental changes in Southern Oceans ZOO*4910 Integrative Vertebrate Biology Group 04 Candace Flynn (cflynn@mail.uoguelph.ca), Melissa Westaway, Katherine Znotinas, and Daniela Banda Marin 2 November 2014 Abstract Reasons for divergence within the animal kingdom is heavily debated across many orders. Macroevolution in Cetacea has been attributed to a variety of…

The earth is reliant on various reproductive biochemical cycles, to maintain balanced and regulated conditions on earth and within the atmosphere (Name, date). These cycles include the carbon, nitrogen and hydrological cycles. These cycles among others, bring with them various geological, chemical, physical and biological processes (name, date). All these cycles are interconnected; matter within them is continually cycled between biotic and abiotic parts of the environment (name, date). Without…

What a coincidence that after the American Industrial Revolution in the 1760 's-1840 's, 40 years later the Earth began to warm up. The Earth begins to warm up due to the amount of carbon dioxide that is released to the atmosphere. During this time period to this day, humans have destroyed the environment and have replaced them with industries, houses , and etc increasing the amount of carbon dioxide rapidly. This new change has erupted various catastrophic consequences such as climate change,…

“The release of atom power has changed everything except our way of thinking the solution to this problem lies in the heart of mankind. If only I had known, I should have become a watchmaker” (Einstein, 1945). Einstein thinks that Nuclear energy knowledge are able to change the world for better than before because it can produce the energy more easily. Also, he know that nuclear energy knowledge has trouble aspects that may people exploit it to hurt other people. Nevertheless, what distinguishes…

As the amount of anthropogenic CO2 has been rising in the atmosphere, this has meant a natural rise in the levels of CO2 in the oceans. This rise can have a large effect on the natural biogeochemical cycles of the oceans. The largest effect will be seen through the acidification of the oceans. When CO2 is dissolved in seawater it increases the concentration of hydrogen ions in the ocean, which then decreases the overall pH, causing acidification. This acidification can have a detrimental effect…

Furthermore consumerism has caused economic problems for people since people are investing into items that cannot bring them more money. This is all down to the mentality of the people, consumers purchase products for a sense of accomplishment and momentary happiness, and once that ends they need to buy another product. Eventually from buying and buying and buying people may end up in debt and what was first intended for happiness may cause sadness and depression due to looking for happiness…

Deforestation increase the level of carbon dioxide in the atmosphere because when trees are burned carbon dioxide is released, carbon dioxide is also, released when trees are decomposed by microorganisms. Cutting down trees also, reduces the amount of carbon dioxides taken up by the photosynthesis and trapped in the wood and carbon dioxide is greenhouse gas therefore, Trees play a huge role in the carbon cycle. They convert the CO2 in the air to oxygen, through the process of photosynthesis.…

Help! Our Planet is in Danger “Beyond Petroleum” was once the slogan of the big oil giant BP, before the company decided to pull the plug on its decades of R&D work on alternative energy. The organization had promised to spend a major portion of its investments on its energy efficiency and renewable energy research programs, but later, the company defaulted much of its capital on various ways to extract fossil fuels. When big oil companies like BP, Exxon Mobil and Chevron put their financial…

Steingraber argues that the fossil fuels humans are so dependent upon are harming the Earth, the animals on Earth, and the people on Earth. “Follow the first branch and you find droughts, floods, acidifying oceans, dissolving coral reefs, and faltering plankton. Follow the second branch and you find pesticides in children’s urine, lungs stunted by air pollutants, abbreviated pregnancies, altered hormone levels, and lower scores on cognitive tests.” (745) “Indeed, according to the most recent…

There are many factors that contribute to the conclusion that the steelhead trout will and will not be able to reestablish themselves in the Arroyo Del Valle presently. Some of the most important factors for the re-establishment of the trout are the relatively stable pH, adequate DO levels, and low pollution. From our graphs, it is evident that the pH of the creek is consistent around 7, which is a pH that the steelhead can establish themselves and live in. Steelhead trout require a DO level…
