VARIABLE PREDATION REGIMES PREDICT THE EVOLUTION OF SEXUAL DIMORPHISM IN A POPULATION OF THREESPINE STICKLEBACK by Reimchen, T. E., Nosil, P.

“…Sexual dimorphism is widespread in nature and can be influenced by sex‐specific natural selection resulting from ecological differences between the sexes. Here…”

TEMPORAL VARIATION IN DIVERGENT SELECTION ON SPINE NUMBER IN THREESPINE STICKLEBACK by Reimchen, T. E, Nosil, P

“…Short-term temporal cycles in ecological pressures, such as shifts in predation regime, are widespread in nature yet estimates of temporal variation in the…”
