The East River Valley is located approximately 120 miles southwest of
Denver, Colorado. It is a glacially-carved valley at 9500ft elevation,
just north of the town of Crested Butte and near the Rocky Mountain Biological Laboratory.
This foodweb image depicts a trophic species
web that is currently being analyzed by Neo Martinez and Brett Harvey.
For more information, contact Neo Martinez.
The web
structure in the image is organized vertically, with node color
representing trophic
level. Red nodes
represent basal
species, such as plants and detritus, orange nodes represent
intermediate
species, and yellow nodes represent top species or primary predators.
Links characterize the interaction between two nodes, and the width of
the link attenuates down the trophic cascade (i.e. a link is thicker at
the predator end and thinner at the prey end). (East River Valley
