Allometric differences when considering facultative cleaners and you will non-cleansers
Allometry of characteristics
Different activities from scaling emerged when we checked out the fresh new ontogeny regarding vertical gape length, maxillary kinematic indication coefficient (KT), jaw protrusion distance and you will bite push to possess Thalassoma wrasses (Fig. 1; discover and additional question Fig. S1 to possess types-certain designs). More Thalassoma wrasses showed some type of allometry from inside the these types of practical faculties. Gomphosus varius exhibited one particular uniform trend out-of allometry across most of the five faculties, exhibiting bad allometry in per instance. Generally, each characteristic, just about about three species exhibited isometry.
All wrasses exhibited strong relationships between logten vertical gape distance and log10 body length (R 2 =0.nine4–0.99, all P<0.0001; supplementary material Table S2). The standardized major axis (SMA) regression slopes ranged from 0.51 to 1.58. While non-cleaner taxa exhibited either isometry or negative allometry for vertical gape distance, facultative cleaners almost universally exhibited positive allometry (Fig. 1A). Thalassoma duperrey was the only facultative cleaner to exhibit isometry for this trait.
Scaling of functional traits in all 11 species. The following traits are shown plotted against log10 body length: (A) log10 vertical gape distance, (B) log10 premaxillary protrusion distance, (C) log10 total bite force (as estimated by MandibLever 3.3) and (D) maxillary kinematic transmission coefficient (KT). Solid, orange lines indicate regressions for facultative cleaner fishes; blue dashed lines indicate regressions for non-cleaner fishes. Vertical gray lines indicate mean and s.d. of critical x-values indicated by the Wilcox procedure for all comparisons.
