Within the scientific community it is more and more recognized that the extrapolation of results from laboratory toxicity experiments to complex field communities requires the analysis of the interactions between different trophic levels in ecosystems, which can be done by means of model ecosystems and mechanistic modelling.
Therefore, undisturbed old field communities should exhibit higher phylogenetic dispersion than recently disturbed systems, which should be relatively 'clustered' with respect to phylogenetic relationships.
The questions addressed here are: 1) Are recently disturbed old field communities different than undisturbed communities both in species composition and phylogenetic composition?; 2) Is the phylogenetic structure of recently disturbed communities systematically different than that of undisturbed communities?
