摘要

可育杂交种能提高种群内的遗传多样性,掩盖有害隐性等位基因的影响,并促进有益基因变体向亲本物种的导入,从而增强物种在压力下的适应能力和复原力。然而,许多杂交种不能生育。我们比较了在水族箱中饲养的 F1 杂交珊瑚和纯种珊瑚(Acropora loripes 和 Acropora kenti)的繁殖力,并考察了第二代(F2)杂交和回交刨形幼虫和新生幼虫早期生命阶段的存活率。F1杂交种产生了有活力的配子,F2杂交种和回交胚胎发育成刨状幼虫,并定居成为无梗珊瑚新成员。在水族馆环境中,F1 杂交种比 F1 A. loripes 纯种种群具有更高的繁殖能力,这是基于它们的产卵概率以及利用其配子进行杂交的受精成功率。因此,种间珊瑚杂交种可以繁殖,并具有较高的生殖适应性,这将有利于受威胁珊瑚礁的持续生存。

Fertile Hybrids Could Aid Coral Adaptation

Fertile hybrids can enhance the adaptive capacity and resilience of species under stress by increasing genetic diversity within populations, masking the effects of deleterious recessive alleles, and facilitating the introgression of beneficial genetic variants into parental species. However, many hybrids are infertile. We compared the fertility of aquarium-reared F1 hybrid and purebred corals of the species Acropora loripes and Acropora kenti and examined the viability of early life stages of second-generation (F2) hybrid and back-crossed planula larvae and recruits. The F1 hybrids spawned viable gametes and the F2 hybrid and back-crossed embryos developed into planula larvae and settled to become sessile coral recruits. The F1 hybrids had greater reproductive fitness than the F1 A. loripes purebred stock in an aquarium environment based on their probability of spawning and their fertilization success in crosses using their gametes. Interspecific coral hybrids can therefore be fertile and have high reproductive fitness, which could benefit the persistence of threatened coral reefs.

期刊介绍: Ecology and Evolution is the peer reviewed journal for rapid dissemination of research in all areas of ecology, evolution and conservation science. The journal gives priority to quality research reports, theoretical or empirical, that develop our understanding of organisms and their diversity, interactions between them, and the natural environment. Ecology and Evolution gives prompt and equal consideration to papers reporting theoretical, experimental, applied and descriptive work in terrestrial and aquatic environments. The journal will consider submissions across taxa in areas including but not limited to micro and macro ecological and evolutionary processes, characteristics of and interactions between individuals, populations, communities and the environment, physiological responses to environmental change, population genetics and phylogenetics, relatedness and kin selection, life histories, systematics and taxonomy, conservation genetics, extinction, speciation, adaption, behaviour, biodiversity, species abundance, macroecology, population and ecosystem dynamics, and conservation policy.
