Previous chapters have outlined the classic concept of plasticity, its mechanistic basis, and
its adaptive importance. Plasticity is the ability of an individual organism or genotype to …

Comparative biogerontology has much to contribute to the study of aging. A broad range of
aging rates have evolved to meet environmental challenges, and understanding these …

Maternal age has a negative effect on offspring lifespan in a range of taxa and is
hypothesized to influence the evolution of aging. However, the mechanisms of maternal age …

To determine the effects of tributyltin (TBT) upon multiple exposures of diet and microplastic
in rotifer, in vivo life parameters were measured. In 10 μg/L TBT-exposed rotifer, the 1 and …

Individuals within populations vary enormously in mortality risk and longevity, but the causes
of this variation remain poorly understood. A potentially important and phylogenetically …

Background Understanding gene expression changes over lifespan in diverse animal
species will lead to insights to conserved processes in the biology of aging and allow …

To examine the interrelationship of aging extension and modification of lipid metabolism
under chronic caloric restriction (CCR; reduced concentration of the green algae Tetraselmis …

Freshwater cyanobacterial blooms are a worldwide environmental issue. These blooms
often comprise both non‐toxic and toxic species and strains. Populations of some …

Maternal effect senescence—a decline in offspring survival or fertility with maternal age—
has been demonstrated in many taxa, including humans. Despite decades of phenotypic …

Variance among individuals in fitness components reflects both genuine heterogeneity
between individuals and stochasticity in events experienced along the life cycle. Maternal …
