Dine and dash: How trophic ecology and migration shape functional locomotory traits in Clupeiform fishes

Understanding how interactions between multiple selective forces influence traits at the macroevolutionary scale is key to understanding adaptive landscapes. Diadromy, an extreme form of migration between marine and freshwater environments, is thought to require locomotory traits conducive to long-distance migration. Yet, other selective forces, such as predator avoidance, habitat use, and prey acquisition, are also likely to shape locomotory adaptation in fishes. We examined how diadromy and trophic ecology together influenced locomotory trait diversity across Clupeiformes, a clade of fishes containing high trophic diversity and numerous transitions to diadromy. We found that both diadromy and trophic ecology influenced the pattern and pace of trait evolution. Diadromous taxa rapidly evolved traits characterized by high cruising efficiency, but the extent to which diadromous and non-diadromous taxa differed depended on their trophic ecology. Macropredators showed greater differences in..., Phylogenetic data comes from Egan et al. (in press). Morphological data was collected for 131 taxa across Clupeiformes using museum specimens. We used a methodology first developed by Gerry et al. (2011) to collect functional locomotory trait data by obtaining the center of mass of a museum specimen. This then allowed us to calculate nine functional indices. For more information on the methods, see Finnegan et al. (2024). , , # Data from: Dine and dash: How trophic ecology and migration shape functional locomotory traits in Clupeiform fishes [https://doi.org/10.5061/dryad.q83bk3jqw](https://doi.org/10.5061/dryad.q83bk3jqw) This dataset is from: Finnegan, D.L., Egan J.P., Bloom, D.D. 2024.

Each column is described below:** Family: family of the species Genus_species: species name Diadromy: categorization of diadromous or non-diadromous Diet: categorization of diet Mass: average mass (grams) SL: average standard length (millimeters) twoMA: average 2nd moment of area (mm^4) Peduncle_ratio: average caudal peduncle r...解析多重选择压力间的相互作用如何在宏观进化尺度上塑造生物性状，是理解适应性景观的核心所在。双洄性（diadromy）是一种往返于海洋与淡水环境的极端迁徙形式，通常被认为需要适配长距离迁徙的运动性状。然而，其他选择压力——如躲避捕食者、栖息地利用与猎物获取——同样可能塑造鱼类的运动适应性。本研究以鲱形目（Clupeiformes）这一具有高度营养生态多样性且多次演化出双洄性的鱼类类群为研究对象，探究双洄性与营养生态如何共同影响其运动性状多样性。研究结果表明，双洄性与营养生态均会对性状演化的模式与速率产生影响。双洄性类群快速演化出以高巡游效率为特征的性状，但双洄性与非双洄性类群间的性状差异程度取决于其营养生态位。大型捕食者类群的性状差异更为显著……系统发育数据源自Egan等人（即将出版）。 本研究依托馆藏标本，采集了鲱形目131个类群的形态学数据。我们采用Gerry等人于2011年首次提出的方法，通过测定馆藏标本的质心来获取功能性运动性状数据，进而计算得到9项功能性指数。有关实验方法的详细信息，请参阅Finnegan等人（2024）的研究。 # 数据集来源：《取食与急行：营养生态与迁徙如何塑造鲱形目鱼类的功能性运动性状》 [https://doi.org/10.5061/dryad.q83bk3jqw](https://doi.org/10.5061/dryad.q83bk3jqw) 本数据集源自：Finnegan, D.L.、Egan J.P.、Bloom, D.D. 2024年发表于《林奈学会生物学杂志》（已接收）的论文《取食与急行：营养生态与迁徙如何塑造鲱形目鱼类的功能性运动性状》 ## 数据与文件结构说明 ### 本数据集包含4个逗号分隔值（.csv）文件 1.
