Maternal resource allocation adjusts to timing of parturition in an asynchronous breeder

Abstract

Abstract: Environmental variation affects foraging decisions and resources available for allocation among competing life-history traits. In seasonal environments, variation in breeding phenology leads to differences in relative timing of resource intake and expenditure, which can lead to variation in maternal allocation tactics. Monitoring maternal allocation to fetal growth in wild mammals is challenging, however, and few studies have linked seasonal effects of forage and maternal condition to early offspring development. Asynchronous parturition and short gestation make kangaroos ideal for studying phenological effects on very early growth, since pouch young born in different seasons can b..
