Human Impacts on island ecosystems. (Australia) There are few paleovegetation records in Australia before 18‚000 years ago. To find out the history of the Australian fauna scientists used stable carbon isotopes from the emu eggshell (a flightless bird native to Australia). The samples were largely taken from Lake Eyre. The carbon composition of the eggshell tells us the composition of the bird’s diet (over 3-5 days). The emus are mixed feeders herbivores‚ eating leaves‚ shoots‚ fruits‚ flowers

Cycles in Biology Cycles in biology play a fundamental role in the world that we live in. Cycles occur all around and inside of us in many different forms‚ from the Krebs to the Calvin cycle. There are large scale cycles happening and they are essential in regulating the nutrients and substances that are around us which without‚ life on earth could no function. One of the largest cycles that occurs all around us is in everyday life is the carbon cycle. The current atmospheric

THE CARBON CYCLE According to the United States Environmental Protection Agency (“EPA”)‚ the increase in anthropogenic CO2 emissions has led to the increase in global temperatures in the past century . Because of the preponderance of evidence linking greenhouse gases and climate change‚ governments worldwide are developing policy to reduce CO2 emissions. CO2 can enter the atmosphere by burning fossil fuels‚ in manufacturing processes‚ and other energy-reliant activities. However‚ not all emitted
