Interpopulation variation in life-history traits of Poeciliopsis prolifica: implications for the study of placental evolution

Placental reproduction is widespread across vertebrate taxa, but little is known about its life‐history correlates and putative adaptive value. We studied variation in life‐history traits in two populations of the placental poeciliid fish Poeciliopsis prolifica to determine whether differences in po...
