Little Rock Lake Trophic Web

Little Rock Lake Trophic Web

Little Rock Lake is a two-basin, mesotrophic lake in northern Wisconsin. The lake is 18 ha, with a maximum depth of 10.3m and an average depth of 3.5m. The food web consists of 93 trophic species, mostly pelagic and benthic species such as fishes, zooplankton, macroinvertebrates, and algae. For more information, see Martinez 1991.

The web structure is organized vertically, with node color representing trophic level. Dark-grey
nodes represent basal species, such as plants and detritus, medium-grey nodes represent intermediate species, and white 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).
