A meta-analysis of competition in field experiments
Article Abstract:
Field-competition experiments from 1980 to 1989 were subjected to meta-analysis to determine the effects of competition on biomass. The experiments dealt with organisms belonging to 93 species from a variety of habitats. Overall, the results showed that competition had a large effect on biomass. Variability of competitive effects according to trophic level, the presence of intraspecific and interspecific competition and other factors are discussed. The results show the usefulness of meta-analysis as a statistical tool to synthesize experimental results from different studies.

Field experimental evidence for diffuse competition among southwestern riparian birds
Article Abstract:
Seventy generally insectivorous riparian bird species in Arizona were studied to determine the effects of communitywise or diffuse interspecific competition in the distribution and abundance of bird populations. The results showed that open-nesting birds avoided experimental plots after addition of boxes. Multivariate analysis showed that this response was true for ecologically diverse species, indicating that communitywise competition is an important determinant of bird distribution and abundance in riparian ecosystems.
