物种的功能能力对其在人为改变的环境中维持可持续种群的能力产生重大影响。对于小海洋岛屿上的淡水鱼类动物群来说尤其如此，这些岛屿上的鱼类经常穿越不同生态系统之间的边界。鱼类功能表现的许多方面与形态特征和局限性直接相关。在这篇综述中，我们以夏威夷群岛的鱼类动物群为例，展示了五种两栖鱼类的习性、栖息地和河内分布与运动和摄食功能形态的关系。此外，我们评估了与功能形态相关的性能限制在不断变化的环境条件下如何影响每个物种。基于此分析，我们提出四项关键建议。 (1) 夏威夷河流管理计划需要根据岛屿的具体情况进行调整。 (2) 由于河口是鱼类和人类之间的交界处，因此需要将其作为重要栖息地进行研究。 (3) 新加入的 Sicyopterus stimpsoni 可能作为监测夏威夷河口长期健康状况的关键指示物种。 (4) 需要严格评估广泛使用生物完整性指数 (IBI) 来评估夏威夷河流健康状况。
The functional capabilities of species can have a strong effect on their ability to maintain sustainable populations in anthropogenically altered environments. This is especially true among species comprising freshwater ichthyofaunas on small oceanic islands, where fishes frequently traverse boundaries between different ecosystems. Many aspects of functional performance in fishes relate directly to morphological features and limitations. In this review, we use the ichthyofauna of the Hawaiian Islands as an example to demonstrate how the habits, habitat, and in-stream distribution of five amphi-dromous fish species relate to the functional morphology of locomotion and feeding. Furthermore, we evaluate how performance limitations related to functional morphology might affect each species under changing environmental conditions. Based on this analysis we make four key recommendations. (1) Hawaiian stream management plans need to be tailored to island-specific conditions. (2) Estuaries need to be studied as a critical habitat because of the interface between fishes and human populations in these areas. (3) New recruits of Sicyopterus stimpsoni might serve as a key indicator species to monitor long-term health of Hawaiian estuaries. (4) The broad use of the Index of Biological Integrity (IBI) to assess Hawaiian stream health needs to be critically evaluated.
