Hormones and Life Histories: An Integrative Approach

Hormones and life histories: an integrative approach.

-This article, which focuses on hormones and the diverse effects they have on behavior and physiology, raises evolutionary questions that hormonal studies appear especially well suited to address. These include the endocrine basis for life-history trade-offs, the role of hormones in adaptive alterations in social organization and mating systems, and whether natural selection acts on traits or o...

Using life-histories to predict and interpret variability in yolk hormones.

Variation in yolk hormones is assumed to provide the plasticity necessary for mothers to individually optimize reproductive decisions via changes in offspring phenotype, the benefit being to maximise fitness. However, rather than routinely expecting adaptive variation within all species, the pattern and magnitude of yolk hormone deposition should theoretically relate to variation in life-histor...

Morphological and life-history responses of anurans to predation by an invasive crayfish: an integrative approach

Predator-induced phenotypic plasticity has been widely documented in response to native predators, but studies examining the extent to which prey can respond to exotic invasive predators are scarce. As native prey often do not share a long evolutionary history with invasive predators, they may lack defenses against them. This can lead to population declines and even extinctions, making exotic p...

Life Histories and Mental Health

A life history approach to understanding four diverse mental health outcomes is presented. The central aim is to begin with richly detailed, “thick” descriptions of individuals’ lives and from them, to discern generalizable features to account for targeted outcomes. Conceptual principles guiding the organization and interpretation of life history information are summarized. Data from the Wiscon...
