管水母是一个未被充分研究的群体水螅动物(刺胞动物)的分支,它们是海洋生态系统中丰富的捕食者,物种存在于整个水柱中。我们(1)综合当前关于管水母营养生态学和捕食者-猎物相互作用的知识,(2)分析管水母-猎物网络,比较浅水和深海栖息地之间的食物网拓扑结构,(3)讨论当代技术,使管水母摄食生态学的研究更加综合,(4)并提出未来研究的愿景。我们发现管水母物种之间的饮食差异,表明管水母占据多个营养生态位和猎物的多样性类群。我们的研究结果表明,管水母-猎物网络可能是更专业化的深海比在上层,这表明潜在的营养差异的深度栖息地。这项研究突出了管水母类之间的生态位分化和营养的复杂性,并展示了胶质浮游动物在塑造远洋生态系统中的食物网结构的重要性。
Siphonophores are a clade of understudied colonial hydrozoans (Cnidaria) that are abundant predators in oceanic ecosystems, with species present across the water column. We (1) synthesize current knowledge about siphonophore trophic ecology and predator–prey interactions, (2) analyze siphonophore‐prey networks to compare food‐web topology between shallow and deep‐pelagic habitats, (3) discuss contemporary techniques that will allow for more integrative studies of siphonophore feeding ecology, and (4) and present a vision for future research. We found distinct diet differences between siphonophore species, indicating that siphonophores occupy multiple trophic niches and prey on a diversity of taxa. Our results suggest that siphonophore‐prey networks may be more specialized in the deep pelagic than in the epipelagic, suggesting potential trophic differences between depth habitats. This study highlights niche differentiation and trophic complexity among siphonophores and demonstrates the importance of gelatinous zooplankton in shaping food web structure in pelagic ecosystems.
