Maternal size and body condition predict the amount of post‐fertilization maternal provisioning in matrotrophic fish

Abstract: Maternal effects often provide a mechanism for adaptive transgenerational phenotypic plasticity. The maternal phenotype can profoundly influence the potential for such environmentally induced adjustments of the offspring phenotype, causing correlations between offspring and maternal traits. Here, we study potential effects of the maternal phenotype on offspring provisioning prior to and during gestation in the matrotrophic live‐bearing fish species Poeciliopsis retropinna. Specifically, we examine how maternal… Show more

“…We wondered if the dramatic morphological differences in Poeciliopsis might be reflected in these closely related populations. We compared the maternal follicle histology, using H&E staining, from two previously studied populations ( Hagmayer et al. 2018 ) and two additional populations, but find no obvious morphological differences ( supplementary fig.…”

“…). Second, the higher degree of placentation of HP females should not be associated with a difference in maternal traits such as proportion of body fat (BF) and standard length (SL), as they are known to influence the degree of placentation (Hagmayer et al 2018). This subprediction is met, as the degree of placentation of HP and LP females is predicted for a female of the same SL and BF.…”

“…Calculation of the MI relies on embryos of different females, and the mass of these embryos might be affected by factors other than stage such as size, age, and body condition of females (Hagmayer, Furness, Reznick, & Pollux, ). In fact, the MI assumes that within a sample of reproductive females, the dry mass of individual embryos only varies as a function of the developmental stage.…”
