Different forms of outdoor recreation have different spatiotemporal activity patterns that may have interactive or cumulative effects on wildlife through human disturbance, physical habitat change, or both. In western North America, shrubsteppe habitats near urban areas are popular sites for motorized recreation and nonmotorized recreation and can provide important habitat for protected species...

A Golden Eagle (Aquila chrysaetos) was evaluated for a balance/equilibrium disorder after suffering trauma due to a hard landing during fi tness training. Magnetic resonance imaging and computed tomography demonstrated a chronic atlanto-occipital subluxation with craniodorsal displacement of the atlas (atlanto-occipital overlapping) causing dynamic brainstem and spinal cord compression and an o...

Biologists routinely use molecular markers to identify conservation units, to quantify genetic connectivity, to estimate population sizes, and to identify targets of selection. Many imperiled eagle populations require such efforts and would benefit from enhanced genomic resources. We sequenced, assembled, and annotated the first eagle genome using DNA from a male golden eagle (Aquila chrysaetos...

Perturbation analysis is a powerful tool to study population and community dynamics. This article describes expressions for sensitivity metrics reflecting changes in equilibrium occupancy resulting from small changes in the vital rates of patch occupancy dynamics (i.e., probabilities of local patch colonization and extinction). We illustrate our approach with a case study of occupancy dynamics ...
