a Free-Living Lizard across a Variable Landscape: Consequences
for Individuals and Populations  PLoS ONE  2012;7(11):e49895.
Current life history theory suggests that the allocation of
energetic resources between competing physiological needs should
be dictated by an individual’s longevity and pace of life. One
key physiological pathway likely to contribute to the
partitioning of resources is the vertebrate stress response. By
increasing circulating glucocorticoids the stress response can
exert a suite of physiological effects, such as altering immune
function. We investigated the effects of stress physiology on
individual immunity, reproduction and oxidative stress, across
an urban landscape. We sampled populations in and around St.
George, Utah, examining corticosterone in response to restraint
stress, two innate immune measures, reproductive output, and the
presence of both reactive oxygen m
