Canonical analysis of principal components (CAP) ordinations.

<p>Differences in assemblage structure of fished species biomass between MPA status and depth at each Guam location (A, B) and between jurisdiction and depth at each level of exposure (C, D). Species correlations with the canonical axis are indicated by the length and direction of vectors.</p

Percentage contribution of spearfishing catches in Guam.

<p>Biomass summed across years from 1985–2005 for trophic group, family groups and species caught by SCUBA (left side dark bars) or snorkel spearfishing (right side light bars).</p

Mean biomass (± SE) of fished species (top row) and primary consumers (bottom row) at each depth.

<p>Comparisons are between fished and MPA sites at each Guam location (Guam West and Guam North) and between Guam and CNMI jurisdictions at each level of exposure (sheltered and exposed).</p

nMDS plot of the relative biomass contribution of species regularly caught by SCUBA spearfishing.

<p>Subsequent years between 1985 and 2005 are linked by a trajectory line and species correlations are indicated by the length and direction of vectors.</p

Boxplots of the lengths of scarines (top row) and acanthurids (bottom row) at each depth.

<p>Comparisons are between fished and MPA sites at each Guam location (Guam West and Guam North) and between Guam and CNMI jurisdictions at each level of exposure (sheltered and exposed).</p

Percentage biomass contributions to catch and average (+ SE) mean length each year.

<p>Family groups; scarines (A) and acanthurids (B) and two frequently caught species; <i>Hipposcarus longiceps</i> (C) and <i>Naso unicornis</i> (D) caught by SCUBA spearfishing (black circles) and snorkel spearfishing (open squares). Significant regression values (p<0.05) indicated by asterisk (*).</p

Study locations in the southern Mariana Islands.

<p>Sample sites denoted as black dots (inside MPAs) and stars (fished areas). Marine protected areas (MPAs) on Guam are indicated by diagonal shading.</p
