cannot be entirely discarded.
In general, fish richness and abundance diminished with reef
distance and the same trend was observed for most fish species but
not for all. Although very few individuals were recorded (N= 6),
the number of I. parvipinnis increased with reef distance. Also, no
GAM was fitted for many other species, such as G. genidens, C. nobilis
and R. porosus, although their abundances were comparable or even
