Meeting Abstract 57.2 Thursday, Jan. 5 The insulin-like growth factor axis as a mediator of life history trade-offs ADDIS, E.A.*; SCHWARTZ, T.S; REDING, D.M.; PALACIOS, M.G.; BRONIKOWSKI, A.M.; Iowa State University addis@iastate.edu Classic life-history theory predicts trade-offs between the lifetime fecundity and lifespan of an individual. However, little is know about the mechanisms that control these trade-offs. […]

Rapid evolution of sex frequency selected by requirement for dormancy and hydroperiod adaptation
Meeting Abstract 57.5 Thursday, Jan. 5 Rapid evolution of sex frequency selected by requirement for dormancy and hydroperiod adaptation SMITH, H.A.*; SNELL, T.W.; Georgia Institute of Technology hilary.smith@gatech.edu In many cyclical parthenogens that alternate between asexual and sexual reproduction, dormant stages produced by the sexual generation allow survival in ephemeral habitats. For example, in monogonont rotifers an […]
