Abstract
A simple, empirical method of detecting evidence of publication bias in meta-analyses is proposed, based on the relationship between the strength of the results in published studies and the quality of the journals in which they appear. In an illustration of its use, the method is applied to published meta-analyses of terrestrial plant competition, predation in streams, woody plant growth under elevated CO2, and marine nutrient enrichment experiments. Statistically significant associations of effect strength and journal quality were found in two of the four meta-analyses.

An adjusted rank correlation test is proposed as a technique for identifying publication bias in a meta-analysis, and its operating characteristics are evaluated via simulations, and the test statistic is a direct statistical analogue of the popular "funnel-graph".

A model for estimation of effect size when there is selection based on one-tailedp-values is described, which offers a test for the presence of publication bias, and corrected estimates of the parameters of the linear model for effect magnitude.

Limitation is quantified with a simple metric, Δr, that estimates the change in the per unit growth rate of phytoplankton directly attributable to addition of a specific nutrient, such as nitrogen, iron, or phosphorus.

It is shown, using multiple meta-analyses taken from the same literature on stream predation experiments, that meta-analytic conclusions can be colored by selection criteria that are not specifically a function of the relevance of the data.

Two general models are proposed that describe how the preponderance of published studies could report significant p-values even when testing a null hypothesis that is, in fact, true.

It is shown that CPOM loading and fish predation were not major forces in determining the diversity, richness, or litter breakdown rates of this lotic community, and suggests that leafpacks function as a refuge from fishpredation for macrobenthic invertebrates.
