Experimentally manipulated lakes had coefficients of variation within the range exhibited by nonmanipulated lakes. Graphical, correlative, and regres

Data on belowground processes and trophic levels higher than herbivores were too rare in the literature to warrant a comparative analysis. All herbivore trophic-level properties were positively correlated with net primary productivity. Different ecosystem types were located

The feeding processes occurring in the ecosystems of the Baltic Sea and the Chesapeake Bay have been parsed into similar 17-node networks of carbon flows, and the use of network analysis to compare the structures reveals that the Baltic ecosystem functions less as a hypertrophic system t

Comparative approaches to ecosystem studies can provide insight into a complex process such as disturbance, but the power to resolve mechanistic questions diminishes as variance among the ecosystems that are compared increases.

Not surprisingly, therefore, the extent to which sediments recycle P to overlying waters is critical in maintaining system productivity and controlling eutrophication of aquatic systems..Re
