由于气候变化导致海平面上升，潮间带珊瑚礁环境正面临全球危机。从协同作用上看，其他人为影响（例如，人口集中在海岸附近造成的环境污染（污水、生境丧失）增加了潮间带生态系统的自然脆弱性。然而，这些威胁的影响长期被忽视，部分原因是对潮间带鱼类生态的某些方面的知识有限。我们测试了什么是主要的差异和驱动程序在三个海洋和三个大陆架（沿海）网站的热带西南大西洋（巴西省）的潮池之间的鱼类组合结构使用标准化的采样方法。海洋和沿海鱼类组合的营养和组成水平的结构明显。值得注意的特有物种率（38-44%）和高密度的海洋网站是由居民物种限制在中，高海岸潮池草食动物是主要的营养组。另一方面，沿海地区以分布广泛的食肉动物物种为主。物理（基质类型、水池高度、潮下带距离和岩石覆盖）、生物（固着动物覆盖）和化学（盐度）参数是影响鱼类空间占有率的驱动力。在这里，明确的证据表明，高鱼类特有性和重要性的特有结构的海洋群落可能会作为最后一根稻草，有利于海洋潮间带珊瑚礁的保护。
Intertidal reef environments are facing a global crisis as climate changes are causing sea-level rise. Synergistically, other human-induced impacts (e.g., sewage, habitat loss) caused by concentration of human populations near the coast increase the natural vulnerability of intertidal ecosystems. However, the effect of these threats have long been neglected due, in part, to a limited knowledge of some aspects of intertidal fish ecology. We tested what are the main differences and drivers in fish assemblages structure between tidepools in three oceanic and three continental shelf (coastal) sites of the tropical southwestern Atlantic (Brazilian Province) using standardized sampling methods. Oceanic and coastal fish assemblages were distinctly structured at the trophic and composition levels. The noteworthy endemism species rate (38–44%) and high densities in oceanic sites are supported by resident species restricted to mid and high-shore tidepools where herbivores were the major trophic group. The coastal sites, on the other hand, were dominated by widely distributed and carnivore species. Physical (substrate type, pool height, subtidal distance and rock coverage), biological (sessile animal coverage) and chemical (salinity) parameters act as the driving forces influencing fish spatial occupancy. Here, clear evidences of high fish endemism and importance of endemics structuring oceanic communities may act as the last straw in favor of the conservation of oceanic intertidal reefs.
