Compared to aquatic ecosystems, experiments on trophic dynamics in many terrestrial food webs are plagued by procedural problems; for example, it may be impossible to exclude top predators while controlling for abiotic variation.

We can also say that the sorts of principles used in understanding trophic dynamics in food web and ecosystem theory do not appear to be of much value in understanding engineering.
Functional feeding groups, therefore, should be used with caution to infer systems-level trophic dynamics in streams (e.
He spends the rest of this chapter discussing patch dynamics, metapopulations, growth, reproductive plasticity, life history considerations, supply-side ecology, and trophic dynamics, particularly in reference to the development of competitively dominant monocultures.
This result provides further evidence that ratio-dependent predation models are better descriptors of trophic dynamics than prey-dependent models.
The equations of Andersen (1997) are easily generalizable and may shed considerable light on processes regulating the apparently high degree of variability in trophic dynamics across ecosystem types.
