Meta-analysis of the effect of temperature, i.e. B 1 - the slope of the regression of temperature and development rate. (A) Forest plot for development rates of hatch to pupation, i.e. larval stages. (B) Funnel plot corresponding to plot (A). (C) Forest plot for development rates from hatch to emergence. (D) Funnel plot corresponding to plot (C). The weight of the study is indicated by the size of the square and the diamond indicates the overall effect estimate from the random effects model. First authors are listed on the left of the forest plots and, when applicable, the strain identifier is listed by number (for full references see Additional file 1: Table S2). Squares represent effect estimates of individual studies. Square size represents the weight given to the study in the meta-analysis, and the horizontal lines represent 95% confidence intervals. Estimated values and confidence intervals are written to the right of the plot. In the funnel plots, points represent the residuals of the model presented in the corresponding forest plot and their associated standard error. When the residuals fit within the light cone, it implies that heterogeneity in the main effect is successfully accounted by the model.
