Streams and Disturbance: Are Cross-Ecosystem Comparisons Useful?Thus, a process such as disturbance may be best studied by comparing similar systems, whereas principles governing simpler attributes, such as decomposition rate or nutrient ratios, may be better elucidated by examining a wide range of ecosystem types.

Stoichiometry of C:N:P Fluxes in Shallow-Water Marine Ecosystemsosystem net organic production, and release implies net consumption. The difference between the nonconservative carbon flux observed minus that estimated by net organic metabolism to account for phosphorus flux defines CO. gas exchange. The difference between observed and expected nitrogen flux defi

The major pattern apparent in our data—that summer chlorophyll responds positively to nutrients and negatively to herbivore size — is congruent with results of whole-lake experiments in which nutrients or predators were manipulated.

This disparity is explained in part by a large indirect subsidy that Chesapeake fishes receive from inputs of allochthonous carbon that is processed for them by the benthic comm

However, structural changes are generally more predictable and may occur earlier or at lower levels of stress than do changes in ecosystem processes. I found several examples of structural changes occurring
