The relationship between body size and trophic position (BS–TP) typically exhibits a positive correlation in aquatic foodwebs, but the strength of this relationship is contingent on ecosystem type and climate. Different hypotheses have been proposed to elucidate climate and ecosystem type effects on the BS–TP relationship for ray-finned fish. However, our understanding of whether such a relationship evolved in a correlated fashion, spanning various climates and ecosystem types, remains limited.

气候和生态系统类型影响鱼类体型和营养位置的相关进化


身体大小和营养位置（BS-TP）之间的关系通常在水生食物网中表现出正相关，但这种关系的强度取决于生态系统类型和气候。人们提出了不同的假设来阐明气候和生态系统类型对辐鳍鱼​​ BS-TP 关系的影响。然而，我们对这种关系是否以相关方式演化、跨越各种气候和生态系统类型的理解仍然有限。
