Fragmentation in South and Central American Rainforests; Draft #1 (outline)

This discussion topic submitted by Dan Radzicki ( radzicdp@miamioh.edu) at 12:21 am on 3/8/01. Additions were last made on Wednesday, May 7, 2014.

I plan on discussing the problem of habitat fragmentation that is effecting the majority of the worlds rainforests. I will focus on three of the main "groups" that are being affected, as well as how and why this occurs. This is an important topic because of the frequency of occurence, and the long lasting effects, that are also difficult to reverse.

-description/definition of fragmentation
-characteristics
-causes (how it occurs)

-effect on rainforest dwelling organisms
-animals
-changes in behavior
-decrease in reproductive fitness
-possibility of extinction

-plants
-how there damage in turn effects the surrounding environ.
-possibility of extinction

-effect on the environment
-specifically the effect of fragmentation in respect to an increase in
emission levels of greenhouse gases

(these three broad points will be simplified using specific examples)
