The lagoon of Moorea Island was characterised by 12 distinct reef zones. Visual censuses allowed us to document the spatial distributions of recently settled juveniles vs adults of 17 nocturnal fish species among the 12 reef zones. Five distinct patterns in habitat use were found: an increase in the number of reef zones used during the adult stage (four species); a decrease in the number of reef zones adults used compared to recently settled juveniles (two species); the use of different reef zones (one species); the use of same reef zones but with relative densities different (one species); and no change in habitat use (nine species). Overall, this study is the first to explore the use of space by a broad range of nocturnal fish taxa to document the patterns and determinism of habitat shifts between juvenile and adult life stages.
莫雷阿岛的泻湖具有12个不同的珊瑚礁区域。通过目视普查，我们得以记录17种夜行性鱼类的幼鱼和成鱼在这12个珊瑚礁区域中的空间分布情况。研究发现了五种不同的栖息地利用模式：成年阶段使用的珊瑚礁区域数量增加（四种鱼类）；与刚定居的幼鱼相比，成年鱼使用的珊瑚礁区域数量减少（两种鱼类）；使用不同的珊瑚礁区域（一种鱼类）；使用相同的珊瑚礁区域，但相对密度不同（一种鱼类）；以及栖息地利用没有变化（九种鱼类）。总体而言，本研究首次探讨了广泛的夜行性鱼类分类群对空间的利用情况，以记录幼鱼和成鱼生活阶段之间栖息地转移的模式和决定性因素。
