Rank order of boldness and height across situations.

<p>A) Ranking of boldness and B) ranking of height across small tanks, large tanks and field site). Each line and unique symbol represents individual fish (N = 33). Individuals were ranked sequentially according to the individual’s observed behavioral trait (1 = highest recorded value). Average ranking scores were assigned when multiple fish had a tie in values.</p

Principal component analysis of 7 behavioral traits for individual fish.

<p>A) PCA traits include: bite rate, distance moved, distance ventured, height, boldness, latency and aggression for individual fish (N = 33) across small tanks, large tanks, and field site (Total N = 99). Factor loadings of these traits represented by arrows in lower left corner. Ovals represent groupings created by clustering analysis. 67% of replicates in group 1 (square symbol) were from observations made in large tanks. 56% of replicates in group 2 (triangle symbol) were from small tanks. Group 3 (diamond symbol) is comprised of 76% of large tank observations. Group 4 (circle symbol) is composed of 42% large tank observations. Group 4 and the combination of groups 1, 2, and 3 represent the first split in the hierarchy. B) Identical principal components analysis with fish plots removed. Arrows represent factor loading patterns for seven randomly chosen fish from small tanks, large tanks, and field site.</p

Principal component analysis of relationships between 7 behavioral traits.

<p>Traits include: bite rate, distance moved, distance ventured, height, boldness, latency and aggression in <i>P. amboinensis</i> in A) small tanks, B) large tanks and C) field situations.</p

Average temperature ranges during behavioral assessments within each situation (small tank, large tank, field situation).

<p>Values of P do not control for multiple testing of the same data (*P<0.05; **P<0.01; ***P<0.001). Only values printed in bold are significant after Holm’s sequential Bonferonni adjustment of experimental error rates (Quinn and Keough 2002).</p
