“…However, these systems do vary in fundamentally different ways, which are likely to have important implications for fertilization success. First, pheromones and other chemotactic attractants may be used by some marine animals to increase fertilization success and outcrossing (for example, Coll et al, 1995;Riffell et al, 2002Riffell et al, , 2004, while filter feeding species have been shown to actively filter out and store sperm from conspecific individuals (Yund, 2000;Hughes et al, 2002). Nevertheless, levels of selfing may be more common in marine animals than is currently recognized and more research is clearly needed to determine the extent of selffertilization and the factors important in maintaining mixed reproductive strategies.…”

“…While some plants have evolved associations with pollinators to assist in the transfer of pollen from one individual to another, no such associations are known for marine taxa. Although pheromones and other chemotactic attractants may be used by some marine taxa to increase fertilization success (for example, Coll et al, 1995;Riffell et al, 2002Riffell et al, , 2004, and despite the potential for decreased fitness due to inbreeding through selfing, the capacity to ensure fertilization in the absence of potential mates or under sperm-limited conditions means that self-fertilization may be an important reproductive tactic for hermaphroditic brooding and broadcast spawning species (for example, Sabbadin, 1971;Heyward and Babcock, 1986;Yund and McCartney, 1994;Cohen, 1996, Brazeau et al, 1998.…”

“…Access to slicks would provide billions of larvae for culture, but the increasing predicability of coral spawning times worldwide may permit direct field harvesting of gametes from spawning colonies (e.g. Coll et al 1995) or from the plankton (e.g. Hodgson 1985).…”

New technologies for culturing and settling scleractinian coral larvae in the field are required to elucidate the role of recruitment in population dynamics and to provide options for reef rehabilitation. Natural multi-species aggregations of coral embryos, which frequently form slicks on the sea surface after large-scale annual spawnings, were identified as a potential resource for mass coral culture. Slicks containing billions of embryos were found at sea and several million embryos were sub-sampled and successfully cultured in simple floating ponds, moored over the reef. Coral larvae were maintained in the floating ponds until competent to settle, and then seeded onto the reef environment via hoses from the ponds to mesh enclosures temporarily fixed to the reef substratum. Reefal areas exposed to the cultured larvae exhibited a dramatic enhancement of coral larval recruitment compared to natural rates. The results demonstrate the ability to seed defined areas of reef with controlled densities of recruits. We conclude that natural spawning slicks, which have been noted on numerous reefs throughout the world, provide opportunities for very large-scale culture of corals, which may have application in reef rehabilitation and management strategies where natural recruitment is limited.

“…Reports by Coma et al (1995) suggest that brooding may be more common with CWC species. In other coral species, Coll et al (1995) suggests that broadcast spawning is most common with Alcyonaceans and brooding occurs most commonly in gorgonian corals. Furthermore, vitellogenesis of mature oocytes in several unidentified species of bamboo corals exist, suggesting that larvae transportation via deep-water currents is possible.…”

Phylogenetic Diversity of the Cold Water Octocoral Paragorgia arborea (Linnaeus, 1758) off the East Coast of Canada

Commonly called "bubblegum coral', Paragorgia is a genus of cold-water gorgonian coral that has a broad global distribution and is eurybathic from depths of meters to kilometers. Such ecological breadth, however, may be confounded by the presence of cryptic species. In this study the genetic distances of various Paragorgia spp. across their distribution and depth range along the Canadian mid-Atlantic margin using 18S ribosomal DNA sequences were compared. Morphometric and 18S evidence show that although appearing closely related, only one species of cold-water Paragorgia, called P. arborea, predominates in this region. However, 18S evidence from corals collected at deep depths located at one site, called the Stone Fence, indicate that a significant amount of divergence exists and other species may also be present. Such new light provides a need for further genetic testing using alternative methods (e.g. microsatellites), which could reveal new lineages that may have considerable ecological and/or taxonomic importance.
