The assumption that the acute response to stress is adaptive is pervasive in the literature,
but there is little direct evidence regarding potential positive fitness consequences of an …

Environments experienced by organisms during early development shape the character and
timing of developmental processes, leading to different probabilities of survival in the …

Life history theory seeks to explain the evolution of the major features of life cycles by
analyzing the ecological factors that shape age-specific schedules of growth, reproduction …

Amphibian populations are declining globally at an alarming rate. Pesticides are among a
number of proposed causes for these declines. Although a sizable database examining …

The purposes of this study were to determine the intervals when placental corticotrophic-
releasing hormone (CRH) was most responsive to maternal cortisol. A sample of 203 …

In species where offspring fitness is sex-specifically influenced by maternal reproductive
condition, sex allocation theory predicts that poor-quality mothers should invest in the …

Amphibian tadpoles display extensive anti-predator phenotypic plasticity, reducing
locomotory activity and, with chronic predator exposure, developing relatively smaller trunks …

The use of pesticides is important for growing crops and protecting human health by
reducing the prevalence of targeted pest species. However, less attention is given to the …

In adult vertebrates, glucocorticoids are thought to trigger transitions between life history
stages within breeding cycles. This review explores possible roles of glucocorticoids as …

Publisher Summary Amphibians exhibit considerable diversity in behavioral, physiological,
and life history strategies. They are geographically widespread, occupying a diverse range …
