Ecology I: The Earth System

We will cover fundamentals of ecology, considering Earth as an integrated dynamic system. Topics include coevolution of the biosphere, geosphere, atmosphere and oceans; photosynthesis and respiration; the hydrologic, carbon and nitrogen cycles. We will examine the flow of energy and materials through ecosystems; regulation of the distribution and abundance of organisms; structure and function of ecosystems, including evolution and natural selection; metabolic diversity; productivity; trophic dynamics; models of population growth, competition, mutualism and predation. This course is designated as Communication-Intensive; instruction and practice in oral and written communication provided. Biology is a recommended prerequisite.

Entire nation of Kiribati to be relocated over rising sea level threat:

In what could be the world’s first climate-induced migration of modern times, Anote Tong, the Kiribati president, said he was in talks with Fiji’s military government to buy up to 5,000 acres of freehold land on which his countrymen could be housed.

Some of Kiribati’s land, which straddle the equator, are already disappearing beneath the waves.

Mission to Drill Ancient Buried Antarctic Lake May Uncover Earth’s Secrets!!!

http://www.reuters.com/article/2011/10/10/us-antarctica-lake-climate-idUSTRE79964Y20111010

An ancient lake hidden deep beneath West Antarctica’s Ice Sheet may reveal vital clues about climate change and future sea level rises, and uncover new forms of life, according to a group of UK engineers and scientist.

    Wow, the chance for discovering prehistoric micro organisms seems likely considering this environment has been entombed under miles of ice for thousands of years. Very interesting project.

I am learining about ecology right now in my science class. We have been learning about different ecosystems, weather, climates and many other things. One thing that my teacher said is that ecology is ECOlogical. There is a lot of information about ecology, but it is easy to understand. One of my favorite topics we learned about was animal relationships. One example that my teacher showed us in class is the ants and acacia trees in a symbiotic relationship. They help and protect each other here is a video about their relationship. Do you all have any other examples of animal realationships?

    Plovers and crocodiles have an interesting symbiotic relationship. The Plover is a bird that hunts for food from the crocodile's open mouth! The crocodile remains still while the plover picks meat from its mouth. This cleans the crocodile’s teeth and prevents infection while providing a somewhat scary meal for the hungry bird. I've posted an image about 5 posts above yours…hope you like it :)

Here’s an interesting short-lecture on coevolution: how species influence each other’s evolution, how they evolve together, mimic each other, or exploit the characteristics of each other.
