Document Summary
Nervous system - carries electrical messages from the brain throughout the body. Endocrine system - carries chemical messages from different organs throughout the body via the blood. Steroids: sex hormones (testosterone, estradiol), adrenal hormones (cortisol, aldosterone) Capture and restraint of the animal (would lead to increase in cortisol) Only tells you about short term variation. Hormone structures are highly conserved, but metabolites are variable (especially between species) Hormones of interest (steroids/peptide- or protein hormones) Species in question - variation in route of hormone excretion and metabolism. Testing for a predicted difference/change (ex: progestogen levels in different reproductive stages; difference in t-levels in relation to reproductive condition, age, gender. Dhea and testosterone have the same metabolites. Males more attracted to females when they"re ovulating (lots of estrogen) Crested-black macaque - scrotum color related to male androgen levels. Any event in which environmental demands, internal demands, or both, tax or exceed the adaptive resources of an individual, social system, or tissue system.
