Selection on Sperm Count, but Not on Sperm Morphology or Velocity, in a Wild Population of Anolis Lizards by Kahrl, Ariel F., Kustra, Matthew C., Reedy, Aaron M., Bhave, Rachana S., Seears, Heidi A., Warner, Daniel A., Cox, Robert M.

“…Sperm competition is a widespread phenomenon that shapes male reproductive success. Ejaculates present many potential targets for postcopulatory selection…”

Climatic factors and species range position predict sexually antagonistic selection across taxa by De Lisle, Stephen P., Goedert, Debora, Reedy, Aaron M., Svensson, Erik I.

Sexual dimorphism explains residual variance around the survival-reproduction tradeoff in lizards: Implications for sexual conflict over life-history evolution by Reedy, Aaron M., Evans, William J., Cox, Robert M.

“…The tradeoff between survival and reproduction is a central feature of life-history variation, but few studies have sought to explain why females of some…”

Behavioral estimates of mating success corroborate genetic evidence for pre-copulatory selection by Bhave, Rachana S, Seears, Heidi A, Reedy, Aaron M, Wittman, Tyler N, Robinson, Christopher D, Cox, Robert M

Maternally chosen nest sites positively affect multiple components of offspring fitness in a lizard by Reedy, Aaron M., Zaragoza, David, Warner, Daniel A.

“…Maternal nest-site choice is a behavioral phenotype with transgenerational consequences that can appear at multiple stages of offspring ontogeny. In many…”

Sperm morphology and count vary with fine-scale changes in local density in a wild lizard population by Kustra, Matthew C., Kahrl, Ariel F., Reedy, Aaron M., Warner, Daniel A., Cox, Robert M.

“…Given that sperm production can be costly, theory predicts that males should optimally adjust the quantity and/or quality of their sperm in response to their…”

Female anoles retain responsiveness to testosterone despite the evolution of androgen-mediated sexual dimorphism by Cox, Christian L., Hanninen, Amanda F., Reedy, Aaron M., Cox, Robert M.

“…Summary The evolution of sexual dimorphism presents a challenge because males and females must express two phenotypes from the same underlying genome. In…”

An acute increase in the stress hormone corticosterone is associated with mating behavior in both male and female red-spotted newts, Notophthalmus viridescens by Reedy, Aaron M, Edwards, Alex, Pendlebury, Chloe, Murdaugh, Laura, Avery, Ryan, Seidenberg, Jake, Aspbury, Andrea S, Gabor, Caitlin R

“…Highlights • Non-invasive waterborne hormone collection was used to measure CORT release in newts. • Courting and non-courting, male and female newts were…”

Do trade-offs between predation pressures on females versus nests drive nest-site choice in painted turtles? by Refsnider, Jeanine M., Reedy, Aaron M., Warner, Daniel A., Janzen, Fredric J.

“…Predation strongly influences reproductive behaviours because reproducing individuals must balance mortality risks to themselves and to their offspring. In…”

Both sexes suffer increased parasitism and reduced energy storage as costs of reproduction in the brown anole, Anolis sagrei by Reedy, Aaron M, Cox, Christian L, Chung, Albert K, Evans, William J, Cox, Robert M

“…Sexual selection theory proposes that males suffer reduced immune function and increased parasitism as costs of expressing sexual signals. Life‐history theory…”
