Resource-dependent investment in male sexual traits in a viviparous fish by Fernlund Isaksson, Erika, Reuland, Charel, Kahrl, Ariel F, Devigili, Alessandro, Fitzpatrick, John L

Rapid evolution of testis size relative to sperm morphology suggests that post‐copulatory selection targets sperm number in Anolis lizards by Kahrl, Ariel F., Johnson, Michele A., Cox, Robert M.

“…Post‐copulatory sexual selection is thought to be responsible for much of the extraordinary diversity in sperm morphology across metazoans. However, the extent…”

Male–male behavioral interactions drive social-dominance-mediated differences in ejaculate traits by Reuland, Charel, Culbert, Brett M, Fernlund Isaksson, Erika, Kahrl, Ariel F, Devigili, Alessandro, Fitzpatrick, John L

“…Abstract Higher social status is expected to result in fitness benefits as it secures access to potential mates. In promiscuous species, male reproductive…”

Consistent Differences in Sperm Morphology and Testis Size between Native and Introduced Populations of Three Anolis Lizard Species by Kahrl, Ariel F, Cox, Robert M

“…Sperm morphology can be highly variable among individuals and across species, but less is known about its variation among populations. Within the past 20–80…”
