Description
Riparian areas are biologically rich ecosystems and invertebrates represent a large proportion of the diversity within them and perform various ecological functions. Benthic aquatic macroinvertebrates have been well studied in relation to their availability as a prey item for brook trout. However, terrestrial allochthonous inputs can account for most of their diet during summer months. Our study looked at three tributaries of the Beebe River in Campton, NH. Two of the tributaries have riparian areas that have been logged and clear cut in recent years and have had more human influence. The third tributary has very little human disturbance. We split the tributaries into zones depending on their riparian zone types. We then quantified the abundance and community composition of terrestrial riparian arthropods in each of the tributaries using pit-fall traps. This allowed us to compare within and between tributaries to see if the differing types of riparian zones has influence on the types and quantity of terrestrial macroinvertebrates that live there. We used chi-square analysis and ANOVA to compare them statistically. Preliminary analyses suggest that there is a significant difference between the sites as well as between riparian zones.
