Experimental brood enlargement differentially influences the magnitude of the corticosterone stress response in closely related, co-occurring songbirds

Creator:

Hardt, Braelei M., Ardia, Daniel R., Bashaw, Meredith J., and Rivers, James W.

Abstract:

1. Rearing environments can shape offspring phenotype across taxa, yet little is known about how brood size influences hypothalamic-pituitary axis functioning, whether its expression trades off with growth, and the degree to which these -relationships vary between species. 2. We evaluated how brood size influenced nestling physiological (glucocorticoids) and somatic...

Experimental evidence that simplified forest structure interacts with snow cover to influence functional connectivity for Pacific martens

Creator:

Moriarty, Katie M., Epps, Clinton W., Betts, Matthew G., Hance, Dalton J., Bailey, J. D., and Zielinski, William J.

Abstract:

Context: Functional connectivity—the facilitation of individual movements among habitat patches—is essential for species’ persistence in fragmented landscapes. Evaluating functional connectivity is critical for predicting range shifts, developing conservation plans, and anticipating effects of disturbance, especially for species affected by climate change. Objectives: We examined whether simplifying forest structure influenced animal...

Article
The use of burned forest by breeding birds following the Biscuit Fire in southwest Oregon

Creator:

Donaghy Cannon, Michelle M.

Abstract:

Fire severity is hypothesized as an important driver of bird responses to wildfire. For those species that typically respond negatively to increasing severity, Accessibility of high-severity burned forest may be dependent on the proximity of unburned or low-severity burned forest to meet all of the needs of breeding bird species...
