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

description: 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
 locomotory traits between diadromous and non-diadromous taxa than
 phytodetritivores and micropredators, suggesting that traits conducive to
 migration might be most costly to consumers of evasive prey. This work
 shows that simultaneously characterizing the roles of multiple ecological
 or life-history factors in phenotypic evolution can bring the topography
 of adaptive landscapes into sharper focus and provide a more holistic view
 of the forces driving patterns of trait evolution.

 Morphological data was collected for 131 taxa across
 <em>Clupeiformes</em> 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).
