Flexible sex allocation in a group-living simultaneous hermaphrodite
Meeting Abstract 38.5 Thursday, Jan. 5 Flexible sex allocation in a group-living simultaneous hermaphrodite HART, Mary K; Univ. of Kentucky, Lexington mkhart0@yahoo.com Phenotypic plasticity can be helpful for maximizing mating success in variable environments and thus may generate different sex allocation patterns among populations. For Serranus tortugarum, a simultaneously hermaphroditic fish, proportional male allocation (testis mass/total gonad […]

Condition-dependent display traits as signals of the functionality of vital cellular processes
Meeting Abstract 38.3 Thursday, Jan. 5 Condition-dependent display traits as signals of the functionality of vital cellular processes HILL, G. E.; Auburn Univ. ghill@auburn.edu Condition is a nearly ubiquitous term in the behavioral, physiological, and evolutionary literature, yet existing definitions are incomplete or ambiguous. Too often in the literature, condition is defined in terms of nutrient reserves. […]

Snake Sex in the City or the Country Different mating aggregation densities generate asymmetry in postcopulatory sexual selection in two populations of red-sided garter snakes
Meeting Abstract 37.3 Thursday, Jan. 5 Snake Sex in the City or the Country? Different mating aggregation densities generate asymmetry in postcopulatory sexual selection in two populations of red-sided garter snakes FRIESEN, Chris/R*; ESTES, Suzanne; MASON, Robert/T; Oregon State Univ.; Oregon State Univ.; Portland State Univ. friesenc@science.oregonstate.edu Models show that reproductive traits may quickly diverge via a […]
Sexual selection in the mimic poison frog Ranitomeya imitator
Meeting Abstract 37.6 Thursday, Jan. 5 Sexual selection in the mimic poison frog Ranitomeya imitator TWOMEY, Evan*; SUMMERS, Kyle; East Carolina University; East Carolina University evan.twomey@gmail.com Understanding mechanisms that promote population divergence has been a central topic in evolutionary research and is key to our understanding of speciation and global biodiversity. In several examples of Müllerian mimicry, […]
