The palatability of 35 non-encrusting, subtidal macroalgal species collected from the vicinity of Palmer Station, Antarctica (64° 46’ S, 64° 03’ W), was determined in laboratory bioassays utilizing… (More)
Palatability of outer tissues of a suite (12 species) of Antarctic ascidians was evaluated using omnivorous fish and sea star predators. Tissues of 100% of those tested were unpalatable to fish,… (More)
