Transgenerational Effects of Maternal Age on Offspring Fitness in Crickets
<p>Advanced parental age is an important aspect of parental condition that can have both positive and negative effects on offspring fitness, and thus, parental age can be considered a parental effect. As a parental effect, parental age may affect a variety of offspring traits and may cascade to …

Black-white differences in postsecondary educational attainment
… models were used to estimate the total effect of personal characteristic variables such as ability, curriculum, and grades on educational attainment and to compare the advantage of father's presence in the household as it contributes to educational attainment. The present study finds the …

Individual and Interactive Effects of Maternally- and Trophically-Derived Mercury on Early Amphibian Development
… to examine the bioaccumulation and ecological effects of environmentally relevant Hg exposure routes acting at various early life stages in amphibians. By collecting amphibians in the field at the Hg-contaminated South River, VA, I confirmed that amphibians exhibiting different life histories …

The neuroendocrine and molecular mechanisms underlying stress-induced maternal effects in the threespine stickleback
Non-genetic maternal effects occur when offspring phenotype is influenced non-genetically by a mother’s phenotype. Exposure of mothers to external stressors, for example, can influence the expression of a wide array of offspring traits essential for survival, including growth, morphology, and …

Consequences of avian parental incubation behavior for within-clutch variance in incubation temperature and offspring behavioral phenotypes
Parents can have large effects on their offspring by influencing the early developmental environment. In birds, a major way that parents can influence the early developmental environment is through egg incubation. Not only is incubation necessary for hatching success, but small changes of <1C in …

Proximate and Ultimate Consequences of Stressed-Induced Maternal, Paternal, and Joint Parental Effects in a Changing World
<p>Parental experience can alter the developmental and rearing environments of offspring, resulting in parental effects on offspring traits. I addressed the consequences of stress-induced maternal, paternal, and joint parental effects from both ultimate (ecological/evolutionary) and proximate …
