Demography of the Yellowstone grizzly bears Demography of the Yellowstone grizzly bears
We undertook a demographic analysis of the Yellowstone grizzly bears (Ursus arctos) to identify critical environmental factors controlling grizzly bear vital rates, and thereby to help evaluate the effectiveness of past management and to identify future conservation issues. We concluded that, within the limits of uncertainty implied by the available data and our methods of data analysis...

Fire and aquatic ecosystems in forested biomes of North America Fire and aquatic ecosystems in forested biomes of North America
Synthesis of the literature suggests that physical, chemical, and biological elements of a watershed interact with long‐term climate to influence fire regime, and that these factors, in concordance with the postfire vegetation mosaic, combine with local‐scale weather to govern the trajectory and magnitude of change following a fire event. Perturbation associated with hydrological...

A GIS modeling method applied to predicting forest songbird habitat A GIS modeling method applied to predicting forest songbird habitat
We have developed an approach for using “presence” data to construct habitat models. Presence data are those that indicate locations where the target organism is observed to occur, but that cannot be used to define locations where the organism does not occur. Surveys of highly mobile vertebrates often yield these kinds of data. Models developed through our approach yield predictions of...

Breeding bird responses to three silvicultural treatments in the Oregon Coast Range Breeding bird responses to three silvicultural treatments in the Oregon Coast Range
Silvicultural alternatives to clear-cutting have been suggested to promote development, retention, or creation of late-successional features such as large trees, multilayered canopies, snags, and logs. We assessed bird response to three silvicultural alternatives to clear-cutting that retained structural features found in old Douglas-fir (Pseudotsuga menziesii) forests and that imitated...
