TLDR
Comparative tools for hormonal analysis provide insights into evolu-tionary theories based on behavioural aspects, such as productive suppression and the ‘challenge hypothesis’, and provides the resolution needed for studies of main behavioural trends, especially in stablehierarchical social systems.About:

Journal ArticleDOI
Hair cortisol as a biological marker of chronic stress: current status, future directions and unanswered questions.
TL;DR: Because of its ability to provide a long-term, month-by-month measure of systemic cortisol exposure, hair cortisol analysis is becoming a useful tool, capable of answering clinical questions that could previously not be answered by other tests.
Journal ArticleDOI
Measuring stress in wildlife: techniques for quantifying glucocorticoids
Michael J. Sheriff,Michael J. Sheriff,Ben Dantzer,Brendan Delehanty,Rupert Palme,Rudy Boonstra +5 more
TL;DR: An overview of the four main biological samples that have been utilized, their advantages and disadvantages for use with wildlife, and some of the background and pitfalls that users must consider in interpreting their results are given.
Journal ArticleDOI
Analysis of cortisol in hair--state of the art and future directions.
TL;DR: Evidence on a recent methodological development assumed to provide a considerable advancement in the analysis of cortisol in hair is discussed, which holds great promise to significantly enhance current understanding on the role of steroid hormones in psychoimmunological research.
Journal ArticleDOI
An assessment of cortisol analysis in hair and its clinical applications
TL;DR: This review uses emerging evidence to describe the usefulness of hair analysis for cortisol and discusses the current methods used.
Journal ArticleDOI
A non‐invasive stress assay based upon measurement of free cortisol released into the water by rainbow trout
TL;DR: It was confirmed that cortisol concentrations in water and estimated cortisol release rates increased in response to handling stress, and that both were correlated with plasma cortisol concentrations.

TL;DR: An unusual data set on Air Force veterans enables this work to compare the basal and reciprocal models as explanations for the relationship between T and divorce, and discusses sociological implications of these models.

Genetic tagging of free-ranging black and brown bears
John G. Woods,David Paetkau,David Lewis,Bruce N. McLellan,Michael F. Proctor,Curtis Strobeck +5 more
TL;DR: This work investigated the genetic variability of American black bears and brown bears in the Columbia River basin of British Columbia, Canada, and developed a method to obtain genetic samples from free-ranging bears, and established the background genetic variability using microsatellite genotyping at 9 loci using tissue and blood samples from captured bears.

Stress-induced suppression of testicular function in the wild baboon: role of glucocorticoids.
TL;DR: In an ongoing study of endocrine function in wild olive baboons living freely in Kenya, sustained social stress was associated with suppressed testosterone (T) concentrations in males as discussed by the authors, and the testes appeared to be the principal site of this inhibition; DEX did not alter LHRH-induced pituitary secretion of LH, somewhat attenuated LH bioactivity, but caused a complete suppression of LH-induced testicular secretion of T.

Behavioural patterns associated with faecal cortisol levels in free-ranging female ring-tailed lemurs, Lemur catta.
TL;DR: It is suggested that faecal cortisol measures can be used to assess seasonal and individual differences in adrenal activity in this lemurid primate, and that this measure could provide a means for quantifying physiological stress in free-ranging animals.
