We studied Mexican spotted owl (Strix occidentalis lucida) diets and the relative abundance and habitat associations of major prey species in a ponderosa pine (Pinus ponderosa)–Gambel oak (Quercus gambelii) forest in north-central Arizona, USA, fro

To better manage aquatic and riparian ecosystems, knowledge of streamflow return intervals is essential. This leads hydrologists and planners to often question how many years of record are necessary to adequately estimate streamflow characteristics.

Six seed sources in two 22-yr-old ponderosa pine, Pinus ponderosa variety scopulomm Engelmann , provenance plantings in Hastings, NE, and Alliance, NE, were evaluated for abundance of Rhyacionia bushnelli, Retinia metalliea, Dioryctria spp ., and Per

Roadless areas on public lands may serve as environmental baselines against which human-caused impacts on landscape structure can be measured. We examined landscape structure across a gradient of road densities, from no roads to heavily roaded, and a

We evaluated the preferences of larval spring cankerworm, Paleacrita vernata (Peck), for 36 Siberian elm, Ulmus pumila L., clones in laboratory experiments. These clones were selected for superior morphological characteristics, apparent nonpreference

A response surface design was used to help define the "nutritional niche" of the western spruce budworm, Choristoneura occidentalis. We evaluated how calcium, magnesium, and phosphorus interacted to influence budworm fitness on artificial diets conta

Wildlife management and policy decisions are increasingly being made at the regional, national and international level. Much of the motivation for extending the geographic context of resource planning comes from U.S. federal laws that require resourc

When the Thomas Creek, Arizona, USA, watershed was logged for the first time, the latest state-of-the-art harvesting was applied. Trees were cut in patches and by group selection, and logs skidded by crawler tractor. Although overland flow and sedime

Riparian communities in the southwestern United States often occur in patches and isolated pockets along stream corridors, making classifications of community types highly dependent on sampling design and methodology. We investigated the relationship
