“…The sex pheromones of most marine invertebrates are released at the same time as the gametes (e.g. Hardege et al 1996, Zeeck et al 1998, and other haliotid studies suggest it is the presence of the eggs themselves that induces sperm release (e.g. Morse et al 1977).…”

The spawning biology of the tropical abalone Haliotis asinina on Heron Reef, Australia, was investigated to identify putative environmental and endogenous factors controlling spawning. Spawnings by H. asinina were highly regular and, in comparison to most other haliotids and marine invertebrates, frequent and extremely synchronous. These events appeared to be regulated by more than 1 environmental cue. The spawning season of H. asinina extends from October to April and is associated with an increase in water temperature. During the spawning season, recently captured abalone, housed in flow-through aquaria, released gametes for 2 nights every 2 wk during the new and full moons. However, the exact date of spawning did not correlate precisely with the lunar cycle. Occasionally the spawning events between 2 populations of H. asinina on Heron Reef that were 1.5 km apart differed by 1 d, suggesting that differential tidal regimes might influence the date of spawning. The population that was exposed to slightly longer spring low tides occasionally spawned 1 d earlier.In the aquaria, the onset of male spawnings was earlier than the onset of female spawnings by an average of 31 min. The time of spawning of either sex was highly correlated with the evening high tide; males spawned an average of 19 min prior to the high tide, and females spawned 11 min after the high tide. Spawnings were highly synchronous amongst individuals, with 90% commencing spawning within 89 min of the first individual that spawned. A greater percentage of individuals spawned when in the presence of the opposite sex and the frequency of male ejaculation was greater when in the presence of females. Synchronous spawning patterns persisted for 6 wk in H. asinina maintained in aquaria; after this period, spawnings continued but were irregular and asynchronous. We propose that low tide exposure and time of high tide indirectly regulate the date and time of spawning respectively, and that these tidal elements influence the spawning biology of H. asinina by maintaining endogenous rhythms that persist in non-tidal environments for at least 6 wk.

“…Water-borne chemicals initiate feeding behaviors and play large roles in determining food choice (Hay 1996, Zimmer-Faust 1989, and organisms (including single cells, zooplankton, snails, urchins, crustaceans, and fish) find food using chemical trails or plumes (Koehl 2006, Weissburg 2000. Reproductive processes such as recognizing or locating potential mates also are mediated frequently by water-borne chemicals (e.g., Doall et al 1998, Hardege et al 1996. Organisms use chemicals to detect and recognize dominant versus subordinate individuals (Breithaupt & Atema 2000, Gherardi & Daniels 2003.…”

Chemical cues mediate many critical life processes, such as feeding, reproduction, and benthic settling, for aquatic organisms. Depending on the fluid velocity and flow regime, released chemicals are transported via diffusion, laminar advection, or turbulent advection prior to organism reception. Here, we review transport mechanisms and ecological consequences in each regime. We discuss cue structures in terms of concentration gradients, concentration fluctuations, and spatial patterns and draw conclusions about strategies that animals use to acquire information. In some cases, chemical transport occurs through a combination of mechanisms, which requires a multiscale analysis. Regime and scaling are major themes that emerge from recent research. In particular, nondimensional parameters that combine biological and physical variables reveal general principles under which organisms respond to chemical cues and facilitate defining regimes of behavior. 73 Annu.

“…Ciliated cells underlie several annelid sensory modalities (including vision, mechanoreception, and chemoreception) that are processed by the central nervous system (Mill, 1978). Among these senses, chemoreception modulates a variety of ecologically important behaviors including spawning (Hardege et al, 1996;Hardege and Bentley, 1997;Hardege, 1999), possibly spermataphore transfer in spionids (Rice, 1978(Rice, , 1991, larval settlement (reviewed by Qian, 1999), juvenile postsettlement movement (Woodin et al, 1995), and feeding (Copeland and Weiman, 1924;Rullier, 1950;Ferner and Jumars, 1999;Kihslinger and Woodin, 2000;Riordan and Lindsay, 2002;Mahon and Dauer, 2005).…”

Evidence suggests that ciliated sensory structures on the feeding palps of spionid polychaetes may function as chemoreceptors to modulate deposit-feeding activity. To investigate the probable sensory nature of these ciliated cells, we used immunohistochemistry, epi-fluorescence, and confocal laser scanning microscopy to label and image sensory cells, nerves, and their organization relative to the anterior central nervous system in several spionid polychaete species. Antibodies directed against acetylated alphatubulin were used to label the nervous system and detail the innervation of palp sensory cells in all species. In addition, the distribution of serotonin (5-HT) and FMRFamide-like immunoreactivity was compared in the spionid polychaetes Dipolydora quadrilobata and Pygospio elegans. The distribution of serotonin immunoreactivity was also examined in the palps of Polydora cornuta and Streblospio benedicti. Serotonin immunoreactivity was concentrated in cells underlying the food groove of the palps, in the palp nerves, and in the cerebral ganglion. FMRFamide-like immunoreactivity was associated with the cerebral ganglia, nuchal organs and palp nerves, and also with the perikarya of ciliated sensory cells on the palps.
