Concordant estimates of countergradient growth variation in striped bass (Morone saxatilis) using comparative life-history data
Abstract:Latitudinal growth compensation (i.e., countergradient growth) is increasingly suspected to be pervasive across diverse taxa. However, a major challenge limiting wider exploration of this topic lies in the difficulty of quantifying these relationships. Common garden experiments, and ideally genetics, remain the only true methods for understanding the genetic basis for compensatory growth. However, previous research suggests that comparative life-history data might produce concomitant, albeit nonconfirmatory, results on countergradient growth variations. However, there have been no evaluations of the precision of such estimates against those that are experimentally derived. I examined countergradient growth variations using comparative size-at-age data for striped bass (

- Published continuously since 1901 (under various titles), this monthly journal is the primary publishing vehicle for the multidisciplinary field of aquatic sciences. It publishes perspectives (syntheses, critiques, and re-evaluations), discussions (comments and replies), articles, and rapid communications, relating to current research on cells, organisms, populations, ecosystems, or processes that affect aquatic systems. The journal seeks to amplify, modify, question, or redirect accumulated knowledge in the field of fisheries and aquatic science. Occasional supplements are dedicated to single topics or to proceedings of international symposia.
