The frequency distribution of individual body sizes in animal communities (i.e. the size spectrum) provides powerful insights for understanding the energy flux through food webs. However, studies of size spectra in rocky and coral reef communities typically focus only on fishes or invertebrates due to taxonomic and data constraints, and consequently ignore energy pathways involving the full range of macroscopic consumer taxa. We analyse size spectra with co‐located fish and mobile macroinvertebrate data from 3369 reef sites worldwide, specifically focusing on how the addition of invertebrate data alters patterns. The inclusion of invertebrates steepens the size spectrum, more so in temperate regions, resulting in a consistent size spectrum slope across latitudes, and bringing slopes closer to theoretical expectations based on energy flow through the system. These results highlight the importance of understanding contributions of both invertebrates and fishes to reef food webs worldwide.

整合鱼类和无脊椎动物的全球一致的礁石尺寸光谱

动物群落中个体体形的频率分布（即体形谱）为了解通过食物网的能量通量提供了有力的见解。但是，由于生物分类学和数据的限制，在岩石和珊瑚礁群落中对尺寸谱的研究通常仅关注鱼类或无脊椎动物，因此忽略了涉及宏观消费类群的所有能量途径。我们使用来自全球3369个珊瑚礁地点的同位鱼类和大型无脊椎动物数据分析大小光谱，特别关注无脊椎动物数据的添加如何改变模式。纳入无脊椎动物会使尺寸谱变陡，在温带地区更是如此，导致整个纬度的尺寸谱斜率一致，并根据通过系统的能量流使斜率更接近理论预期。这些结果凸显了理解无脊椎动物和鱼类对全世界礁石食物网的贡献的重要性。
