...., 2019 ). For example, maternal hormone allocation can promote the development of phenotypic traits that reduce offspring exposure or susceptibility to predators ( Schwabl et al., 2007 ). Such hormone-mediated maternal effects may be especially important for offspring survival early in life before...

... in the stress response profile between testosterone- and control females before the onset of ovarian growth suggests that photostimulation and/or activation of the hypothalamus–pituitary–ovary axis are required for the expression of this maternal effect in a state-dependent manner; we did not, however, detect...

Here, we sought to modify the maternal mRNA contribution to offspring embryos and test for maternal effects on acute thermal tolerance in early embryos of Drosophila melanogaster . We drove in vivo overexpression of a small heat shock protein gene ( Hsp23...

... in maternal behaviour did not preclude the evolution of geographic differences in thermal effects: offspring growth varied between populations, potentially suggesting local adaptation to basking conditions. Our results demonstrate that maternal effects and phenotypic plasticity can play a significant role...

We suggest that oviduct function is a significant contributor to the physiological costs of egg production and might mediate individual variation in maternal effects associated with non-yolk components of egg quality (e.g. immunoglobulins,lysozyme). * Author for correspondence (e-mail: tdwillia...
