Table 1.

Phylogenetic signal in ecological traits of corals in the subtropical-to-temperate transition zone in eastern Australia using Pagel's λ or D as the test statistic. P (random) and P (Brownian) indicate significance levels of departure from random and from Brownian phylogenetic structure, respectively (p < 0.05). Not significant departure from Brownian structure indicates conserved trait evolution.
