Does food web complexity eliminate trophic-level dynamics?

Article Abstract:

There are general patterns in the productivities, biomasses and abundancies of natural communities. Research on terrestrial and pelagic freshwater communities reveal the existence of patterns in their consumption efficiencies. The quantitative measurement of consumption efficiency validates the presence of general patterns despite the complexity of natural communities.

Implications of dynamically variable traits for identifying, classifying and measuring direct and indirect effects in ecological communities

Article Abstract:

The individual traits and trait value distribution changes with time and the strength of interactions among species is affected by various dynamic traits. A change in the initiator species causing a change in the receiver without affecting other species results in the direct effect of one species on another. Traits and population densities transmit indirect effect.
