本研究描述了在Rangiroa环礁，法属波利尼西亚的15种珊瑚礁鱼的栖息地使用的个体发育转变。在两个珊瑚礁（边缘礁和内礁）的珊瑚为主和藻类为主的网站不同生境中的鱼类在三个个体发育阶段（新定居者，少年，成年人）的分布进行了调查。栖息地利用的个体发生模式主要有三种：（1）在新定居者和幼年生活阶段之间不改变栖息地的物种（60%的物种）或介于幼年和成年阶段之间（55%的物种-无个体发生转移）;（2）在不同个体发生阶段改变生境的物种（“新定居者向幼年阶段”过渡：15%的物种;“幼年向成年阶段”过渡：20%的物种）;和（3）物种，增加了栖息地的数量，他们使用的个体发育（对于“新定居者到幼年阶段”的过渡：25%的物种;对于“幼年到成年阶段”的过渡：25%的物种）。此外，大多数研究的物种（53%）表现出空间变异的个体发育模式的栖息地利用根据交替的珊瑚礁状态（珊瑚礁与藻礁），这表明珊瑚礁状态可以影响栖息地协会在珊瑚礁鱼类的动态。
The present study describes ontogenetic shifts in habitat use for 15 species of coral reef fish at Rangiroa Atoll, French Polynesia. The distribution of fish in different habitats at three ontogenetic stages (new settler, juvenile, and adult) was investigated in coral-dominated and algal-dominated sites at two reefs (fringing reef and inner reef of motu). Three main ontogenetic patterns in habitat use were identified: (1) species that did not change habitats between new settler and juvenile life stages (60% of species) or between juvenile and adult stages (55% of species—no ontogenetic shift); (2) species that changed habitats at different ontogenetic stages (for the transition “new settler to juvenile stage”: 15% of species; for the transition “juvenile to adult stage”: 20% of species); and (3) species that increased the number of habitats they used over ontogeny (for the transition “new settler to juvenile stage”: 25% of species; for the transition “juvenile to adult stage”: 25% of species). Moreover, the majority of studied species (53%) showed a spatial variability in their ontogenetic pattern of habitat use according to alternate reef states (coral reef vs algal reef), suggesting that reef state can influence the dynamics of habitat associations in coral reef fish.
