Lab+11+-+Ecology

= = __**Lab 11- Ecology**__ __**Exercise 1 - Trees**__

I took this photo behind my sister's apartment in Greenville, SC during Easter. The branches are quite sturdy with a middle-ish gray-brown color, and are complete with leaves! The leaves are deciduous, with alternate branching, with simple, unlobed leaves. The bark is non-papered and the stems are round. The leaves are long and narrow, 5-6 inches, hairy, and fringe along the bottom of the leaf. The tree, according to the dichotomous key, is black cherry.

__**Exercise 2 - Birds**__

I found these pigeons and have identified them using the dichotomous key: http://en.wikibooks.org/wiki/Dichotomous_Key/Aves

__**Exercise 3 - Spring Flowers**__

__**Photo taken: Greenville, SC**__

Hydrangeas are the flower above. Using this dichotomous key: http://www.bio.brandeis.edu/fieldbio/Sylvain/keyF.html, I have helped identify them. THey are clustered, non warty-pod bearing, have leaves alternating, and blueish in color.

__**EARTH DAY**__

The "Earth day" talks began in 1962 with Senator Gaylord Nelson. He wanted to put the environment in the political limelight to begin a conservation initiative during JFK's presidency. It overall became a total grassroots-level endeavor and it sort of "organized itself", as he put it, garnering 20 million demonstrators in 1970 to show support for the environment. (Cite: http://earthday.envirolink.org/history.html) Another fact is that it channeled anti-war sentiment to fight for the environment. It enlisted support from all people -- Democrats, Republicans, young, old, African American, Caucasian, rich, poor, city-dwellers, and rural-liversa true MOVEMENT.
