Successful recruitment is critical to the maintenance and resilience of populations and may be at the core of the transition from scleractinian- to octocoral-dominated faunas on some Caribbean reefs. For sessile invertebrates, recruitment incorporates the composite effects of larval supply, settlement and survival. The relative success of these processes differs between species, and successful recruitment may be achieved through different life history strategies. Recruitment of six abundant and widespread Antillogorgia spp. was assessed at six sites on Little Bahama Bank from 2009–2012. Identification of recruits to species level, based on microsatellite analyses, revealed differences in recruitment and survival between species, sites and years. The broadcast spawning species, A. americana and A. acerosa , had low rates of early recruitment and post-settlement survival. Higher levels of recruitment success were achieved among brooding and surface brooding species following somewhat different patterns of early recruitment and survival. The internal brooder A. hystrix had the highest recruitment at five of the sites, but low survival dramatically reduced its abundance and after a year it had similar densities as the surface brooding species, A. elisabethae and A. bipinnata . The brooders have smaller colonies and produce fewer larvae than the broadcast spawning species, but they release competent larvae, which may account for their higher recruitment rates. The Antillogorgia illustrate the diversity of successful reproductive strategies exhibited by octocorals, and differences in the life history strategies among these congeners are best characterized by their mode of larval development.

Antillogorgia spp. 的物种水平鉴定。新兵确定了在加勒比珊瑚礁上获得八珊瑚成功的多种途径

成功的招募对于种群的维持和恢复能力至关重要，并且可能是一些加勒比珊瑚礁上从石珊瑚到八珊瑚为主的动物群过渡的核心。对于无柄无脊椎动物，招募结合了幼虫供应、定居和生存的复合效应。这些过程的相对成功因物种而异，并且可以通过不同的生活史策略实现成功的招募。招募六种丰富而广泛的Antillogorgia spp。2009-2012 年在小巴哈马银行的六个地点进行了评估。根据微卫星分析确定物种水平的新兵，揭示了物种、地点和年份之间的招募和生存差异。广播产卵种 A. americana 和 A. acerosa ，早期招募和定居后存活率较低。在早期募集和存活模式略有不同的育雏和表面育雏物种中实现了更高水平的募集成功。内部育雏 A. hystrix 在五个地点的募集量最高，但存活率低使其丰度显着降低，一年后它的密度与表面育雏物种 A. elisabethae 和 A. bipinnata 相似。与广播产卵物种相比，育雏器的群体更小，产生的幼虫也更少，但它们会释放有能力的幼虫，这可能是它们募集率较高的原因。Antillogorgia 说明了八珊瑚展示的成功生殖策略的多样性，
