Abstract:

Aquatic ecology acknowledges that there are hierarchically nested spatial controls on the relationship between catchment land use and aquatic system integrity, yet previous assessments have often failed to account for influences across multiple scales, in part because of statistical limitations. Hierarchical statistical models may provide a robust method for assessing these relationships across nested scales while avoiding common statistical pitfalls such as collinearity and autocorrelation between scales. We explore the relationship between land use data and Maryland Biological Stream Survey data using both standard and hierarchical regression models.
