Effects of Time-of-day and Tide on fish counts.

Fixed-effect coefficients for levels afternoon and high-tide, and their significance (in parenthesis), and standard deviation (SD) of spatial and residual components of variability. The number of replicates (i.e., number of reefs censused) for each data set is indicated in the “Transects” column. Significance is indicated as: ns = not significant (p>0.05), *  =  significant (p<0.05), **  =  highly significant (p<0.01). Spatial variation was highly significant in all cases.
