Relationships Between Chemical Defense and Ecology in Benthic Ascidians

Thirty-five species of nearshore, benthic ascidians were collected in Bermuda and notes were made on their habitat, microhabitat, susceptibility to epizoic recruitment, morphology, and acidity.

(dry weight); three species had vanadium concentrations of o...
