Ann N Y Acad Sci 1046:35-53. 2005..More studies are urgently needed to learn more about differences between the sexes, individuals, and populations and the impact of diet and energy metabolism on hormone metabolites... - Social status does not predict corticosteroid levels in postdispersal male spotted hyenasWolfgang Goymann
Max Planck Institute for Behavioural Physiology, D 82319 Seewiesen Post, Starnberg, Germany
Horm Behav 43:474-9. 2003..However, males of the largest clan had the highest levels of fecal corticosteroids, possibly reflecting higher rates of social interactions in larger clans... - Low ambient temperature increases food intake and dropping production, leading to incorrect estimates of hormone metabolite concentrations in European stonechatsWolfgang Goymann
Max Planck Institute for Ornithology, Department of Biological Rhythms and Behaviour, Von der Tann Str 7, D 82346 Andechs, Germany
Horm Behav 49:644-53. 2006..Any study involving systematic changes in metabolism--i.e., during molt, migration, hibernation, egg production, or seasonal comparisons--needs to take these caveats into account... - Testosterone in tropical birds: effects of environmental and social factorsWolfgang Goymann

Proc Biol Sci 275:1053-60. 2008..We anticipate that our observation in a sex-role reversed species may provide a more general mechanism, by which progesterone--in interaction with testosterone--may regulate resource-defence aggression in female vertebrates... - Green matters!
