- ItemMaternal Lipid Provisioning Mirrors Evolution of Reproductive Strategies in Direct-Developing Whelks(UNIV CHICAGO PRESS, 2016) Carrasco, Sergio A.; Phillips, Nicole E.; Sewell, Mary A.The energetic input that offspring receive from their mothers is a well-studied maternal effect that can influence the evolution of life histories. Using the offspring of three sympatric whelks: Cominella virgata (one embryo per capsule); Cominella maculosa (multiple embryos per capsule); and Haustrum scobina (multiple embryos per capsule and nurse-embryo consumption), we examined how contrasting reproductive strategies mediate inter-and intra-specific differences in hatchling provisioning. Total lipid content (as measured in mu g hatchling(-1) +/- SE) was unrelated to size among the 3 species; the hatchlings of H. scobina were the smallest but had the highest lipid content (33.8 +/- 8.1 mu g hatchling(-1)). In offspring of C. maculosa, lipid content was 6.6 +/- 0.4 mu g hatchling(-1), and in offspring of C. virgata, it was 21.7 +/- 3.2 mu g hatchling(-1). The multi-encapsulated hatchlings of C. maculosa and H. scobina were the only species that contained the energetic lipids, wax ester (WE) and methyl ester (ME). However, the overall composition of energetic lipid between hatchlings of the two Cominella species reflected strong affinities of taxonomy, suggesting a phylogenetic evolution of the non-adelphophagic development strategy. Inter-and intracapsular variability in sibling provisioning was highest in H. scobina, a finding that implies less control of allocation to individual hatchlings in this adelphophagic developer. We suggest that interspecific variability of lipids offers a useful approach to understanding the evolution of maternal provisioning in direct-developing species.
