“…In the wild, the juvenile stages of abalone are closely associated with non-geniculate coralline algae (Roberts 2001). In laboratory experiments, coralline algae have been found to induce attachment and metamorphosis in all abalone species that have been tested, and there is evidence in some abalone species of settlement preferences for particular coralline species (Daume et al 1999;Moss 1999;Roberts 2001).…”

Calcified macroalgae are distributed in marine habitats from polar to tropical latitudes and from intertidal shores to the deepest reaches of the euphotic zone. These algae play critical ecological roles including being key to a range of invertebrate recruitment processes, functioning as autogenic ecosystem engineers through provision of three-dimensional habitat structure, as well as contributing critical structural strength in coral reef ecosystems. Calcified macroalgae contribute significantly to the deposition of carbonates in coastal environments. These organisms are vulnerable to human-induced changes resulting from land and coastal development, such as altered patterns of sedimentation, nutrient enrichment through sewage and agricultural run-off, and are affected by coastal dredging and aquaculture. The consequences of increasing sea surface temperatures and fundamental changes in the carbon chemistry of seawater due to CO 2 emissions from anthropogenic activities will have serious impacts on calcifying macroalgae. It is not yet understood how interactions between a range of variables acting at local and global scales will influence the viability of calcifying macroalgae and associated ecosystems. Research is urgently needed on all aspects of the taxonomy, biology and functional ecology of calcifying macroalgae. Without an understanding of the species present, measurement of change and understanding species-specific responses will not be possible.

“…This behaviour has been commonly reported for invertebrates (Richmond, 1985;Gebauer et al, 1988;Pechenik et al, 1996;Moss, 1999;Chicharro and Chicharro, 2000) and for some reef fishes (Victor, 1986a,b;Sponaugle and Cowen, 1994;McCormick, 1999). Until now, delayed settlement has been viewed as a larval adaptation to expand the biogeographical range and to increase the chance of finding a suitable habitat in which to settle (Sponaugle and Cowen, 1994).…”

“…We used GABA as a positive control in our study because it previously had been shown to induce larval settlement, attachment and/or metamorphosis in H. iris (Roberts 2001 australis (Moss 1999). However, the effective doses for these species vary between 0.5-10 µmol L -1 , implying species specificity.…”

“…The amino acid and neurotransmitter γ-amino butyric acid (GABA) consistently has been shown to induce larval attachment and metamorphosis of several abalone species (Morse 1990;Roberts & Nicholson 1997;Bryan & Qian 1998;Moss 1999). While a pure-form of GABA is unlikely to be an environmental cue (Kaspar & Mountfort 1995;Roberts & Watts 2010), abalone possess externally accessible chemosensory receptors which recognize GABA analogues and GABA-mimetic peptides extracted from crustose coralline algae (Morse et al 1979(Morse et al , 1980Trapido-Rosenthal & Morse 1986;Morse 1990).…”

Neurophysiological control of swimming behavior, attachment and metamorphosis in black-footed abalone (Haliotis iris) larvae AbstractExperiments were conducted to test the effect of a range of chemicals on larval responses in swimming behavior, attachment, and metamorphosis of the black-footed abalone (Haliotis iris). The effect of antibiotics on larval survival was first tested within negative (filtered seawater) and positive (GABA at 10 -5 , 10 -4 , and 10 -3 mol L -1 ) control assays over 3days. This experiment corroborated the effectiveness of using antibiotics to improve survival of larvae without obvious synergistic interactions with the GABA inducer or confounding effects of potential bacterial interactions. Chemical treatments (acetylcholine, potassium chloride, dopamine, and glutamine) were then tested at various concentrations for their ability to modulate swimming behavior and induce larval attachment and metamorphosis over 14 days. Generally, larval state shifted from swimming to attached, and from attached to metamorphosed in the control and treatments over time. However, the peak percentage of attached and metamorphosed larvae varied in time among chemicals and concentrations.While overall percent metamorphosis was minimally enhanced after 14 days of exposure to some chemical treatments at certain concentrations, all treatments displayed significant capacities to down-regulate larval swimming and induce early attachment and metamorphosis. Mortality was recorded throughout the duration of the experiment, and was generally low (<20%) across controls and most treatments for exposures of less than 12 days.Interpretations of specific results from this study are used to elucidate neurophysiological control of larval activities for this abalone species. Comparisons with other marine 3 invertebrates highlight the specificities of chemical cues and endogenous regulatory mechanisms across relatively closely related taxa. IntroductionChemoreception is believed to facilitate larval settlement processes and metamorphosis of a great number of marine invertebrate taxa, including polychaetes ( algae where bacterial and diatom biofilms are in abundance. However, the involvement of biofilms in the facilitation of settlement and metamorphosis by crustose coralline algae is questionable for some abalone species (Huggett et al. 2005;Roberts et al. 2007.Furthermore, specific settlement-inducing compounds within these natural surfaces have rarely been identified (but see Morse et al. 1980;Suenaga et al. 2004).Another approach to investigate chemoreception and associated transduction mechanisms has been to test specific pharmacologically active compounds for their ability to induce settlement and metamorphosis. The amino acid and neurotransmitter γ-amino butyric acid (GABA) consistently has been shown to induce larval attachment and metamorphosis of several abalone species (Morse 1990;Roberts & Nicholson 1997; Bryan & Qian 1998; Moss 4 1999). While a pure-form of GABA is unlikely to be an environmental cue (Kaspar & M...
