The coralline treatment represented pebbles (approximately 1 cm in diameter) with more than 90% cover of the crustose coralline alga Phymatolithon repandum (Foslie) Wilks and Woelkerling.
The assays exposed larvae to either a coralline alga (as for experiment 1, treatment 9) or a l-mM GABA dip (experiment 1, treatment 8), both of which were highly effective cues in experiment 1.
australis larvae that had attached exceeded 40% in all treatments other than negative controls and exceeded 80% for the 2 treatments containing 1 [micro]M GABA and for the coralline alga Phymatolithon repandum (Fig.
The development of competence to metamorphose was similar for the coralline alga and the GABA dip (Fig.
Survival and growth rates of juvenile turban snail (Turbo cornutus) reared on 2 red algae, an articulated coralline alga
(ACA) Marginisporum crassissima and a gelidicean alga (Agar) Gelidium elegans, with natural and reduced diatom densities were compared to examine the relative importance of algal fronds and epiphytic diatoms as diets for the juvenile turban snail.
