Relationships between male secondary sexual traits, physiological state and offspring viability in the three-spined stickleback.

BMC ecology and evolution - 7 Jan 2022

Chiara Violette, Velando Alberto, Kim Sin-Yeon

Abstract excerpt

BACKGROUND: Sexual signals produced by males play a central role in sexual selection, but the relationship between these traits and the quality of the bearer are often ambiguous. Secondary sexual traits may represent genetic quality of the bearer, resulting in positive relationships with physiological state, or may be costly to produce, showing trade-off with physiological state. A number of studies have explored...
