Simon F. Thrush, Judi E. Hewitt, Alf Norkko, Vonda J. Cummings, and Greig A. Funnell. 2003. Macrobenthic recovery processes following catastrophic sedimentation on estuarine sandflats. Ecological Applications 13:1433–1455.

Appendix A. Complete results of generalized linear models to assess the significance of differences in (1) environmental parameters between experiment and control plots (Table A1), (2) density of important taxa between experiment and control plots ( Table A2), and (3) number of taxa and number of individuals between experiment and control plots (Table A3).

 

Table A1. The significance of differences in environmental parameters between experiment and control plots. Generalized linear models based on either normal or binomial errors for the variables crab burrows and % mud. Mean sum of squares and F values are given for the model and F values for the factors in the analysis for normal errors. Deviance/df and values are given for the model and values alone for the factors in the analysis for variables requiring binomial errors. TRT = treatment; C = control; E = experiment. Where significant time × treatment interaction occur the P value is presented for each time and the direction of the effect (e.g., controls > experimental plots) presented.

Table A2. The significance of differences in density of important taxa derived from the SIMPER analysis between experiment and control plots. Results of generalized linear models use normal or Poisson errors. Mean sum of squares and F values are given for the model and F values for the factors in the analysis for normal errors. Deviance/df and values are given for the model (except where quasi-likelihood functions were required) and values alone for the factors in the analysis for variables requiring Poisson errors. TRT = treatment; C = control; E = experiment. Where significant time × treatment interaction occur the P value is presented for each time and the direction of the effect (e.g., controls > experimental plots) presented.
