Species and Total Population Visuals- Created by Spyglass Transform- Spyglass creates raster images from numerical data.  Each color stands for a different number.  Refer to the bottom two visuals on this page:
 


 These two visuals compare total population and species diversity in a plot near the edge(on the left),and a plot near the center(on the right).  Note the higher population numbers at the south (bottom) edge of plot 1.  What do you think accounts for this difference???
 

                                PLOT 1                                                        PLOT 7

 
With a little more time, we could create a key to  accompany the color bars.
