Seasonal changes of the adrenocortical response to stress in birds of the Sonoran Desert.
Many avian species of the North American Sonoran desert, e.g., the black-throated sparrow, Amphispiza bilineata, cactus wren, Campylorhynchus brunneicapillus, and curve-billed thrasher, ToxostomaExpand

Throat colour reliably signals status in male tree lizards, Urosaurus ornatus
Abstract The use of small patches of colour, called badges, as signals of fighting ability (status signals) across age or sex classes has been well described. Examples of within age- or sex-classExpand

Reproductive endocrinology and mechanisms of breeding inhibition in cooperatively breeding Florida Scrub Jays Aphelocoma C. coerulescens)
Although the ecological and evolutionary bases of cooperative breeding have received close scrutiny, few studies have explored the physiological mechanisms responsible for delayed breeding byExpand

Variation in stress and innate immunity in the tree lizard (Urosaurus ornatus) across an urban–rural gradient
The urban environment presents new and different challenges to wildlife, but also potential opportunities depending on the species. As urban encroachment onto native habitats continues, understandingExpand

Reciprocal changes in corticosterone and testosterone levels following acute and chronic handling stress in the tree lizard, Urosaurus ornatus.
To examine the reciprocal interactions among gonadal and adrenal steroid secretion, male tree lizards (Urosaurus ornatus) were subjected to two forms of stress. They were subjected either to theExpand

The effects of stress on wound healing in male tree lizards (Urosaurus ornatus).
Exposure to stress can affect an organism's partitioning of resources among immune function and other organismal functions. However, measuring immune function is often difficult. Recent studies showExpand

Time and Energy Costs of Aggression in Testosterone-Implanted Free-Living Male Mountain Spiny Lizards (Sceloporus jarrovi)
Several lines of evidence support the hypothesis that free-living male mountain spiny lizards (Sceloporus jarrovi) given testosterone (T) implants experience increased energetic costs as a result ofExpand

Immune activity suppresses reproduction in food‐limited female tree lizards Urosaurus ornatus
Summary 1When resources are scarce, organisms are faced with critical challenges trying to optimize competing functions. Reproduction and immune function are both resource intensive and important toExpand

Plasma corticosterone response to an acute stressor varies according to reproductive condition in female tree lizards (Urosaurus ornatus).
The magnitude of the glucocorticoid response to a stressor can depend on both environmental and physiological context. One factor that has not been examined is whether females of differentExpand
