Synchrony in first differences of indices of abundance of reef fishes off the southeastern United States from headboat data. 
Assemblages are labeled as Deepwater, Southern (south of Cape Canaveral, Florida), and Northern (north of Cape Canaveral, 
Florida). Values are correlation coefficients and proportions of coefficients (in parentheses) from n=10,000 randomizations that 
were smaller than the correlations presented, such that values near 1.0 indicate significance of positive coefficients and values 
near 0.0 indicate significance of negative coefficients. Asterisks note significance at the a=0.1 level with Bonferroni correction 
(two-tailed test). Abbreviations for species names are explained in the Appendix.
