Gradient studies of terrestrial ecosystems are strengthened by a connection to intensive, long-term studies of a single ecosystem at some point along the gradient.

system comparisons in ecology. The contributors, all well-known in their field, support their conclusions on the use and meaning of such comparisons by presenting novel analyses of data utilizing a variety of cross-system approaches in marine, freshwater, and terrestrial systems.978-1-4612-7804-7978

Patterns of Primary Production and Herbivory in 25 North American Lake Ecosystemssis of ecosystems and explain their implications for our study. 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.

Comparing Ecosystem Structures: The Chesapeake Bay and the Baltic Sean fixed in primary productivity reaches the fishes of the Baltic than is transferred up the trophic web of the Chesapeake. 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

Comparative Responses of Aquatic Ecosystems to Toxic Chemical Stressces. Toxic chemical stress can affect both the structure and function of aquatic ecosystems. 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
