The relationship of non-recovered rodent caches to the natural regeneration of ponderosa pine

Creator:: Saigo, Barbara Woodworth
Abstract:: Studies were conducted within a 12-mile radius of Camp Sherman, Oregon, in the Deschutes National Forest during the spring and summer of 1965 and the spring of 1966, with one follow-up visit in the summer of 1967. The feeding and foraging activities of Eutamias amoenus and Citellus lateralis were observed,...

Evaluation of factors affecting natural reproduction of forest trees in central western Oregon

Creator:: Bever, Dale N.
Abstract:: This study was started in 1947 to investigate the value of various types and quantities of seed source in the establishment of reproduction on cutover land, and to determine the apparent effects of various man-made and natural factors upon the rate of restocking. The man-made and natural factors to be...

Regenerating coastal forests in Oregon : an annotated bibliography of selected ecological literature

Creator:: Loucks, Donna M., Knowe, Steven A. (Steven Alan), 1954-, Shainsky, Lauri J., Pancheco, Alex A., and Oregon State University. Forest Research Laboratory
Abstract:: This annotated bibliography was compiled to provide a comprehensive list of sources on the ecological factors that affect forest regeneration. Abstracts from 494 publications are indexed by author, species, and subject, and are arranged into 4 major sections. Topics include the effects of biotic factors, abiotic factors, and stand and...

Environmental contaminants and breeding biology of great blue herons in the Columbia River Basin

Creator:: Thomas, Carmen M.
Abstract:: Great blue heron (Ardea herodias) eggs and prey items were collected from six colonies on the Columbia and Willamette rivers and Puget Sound during 1994-95. Contaminant concentrations, reproductive success, and biomagnification factors (BMFs) were determined and effects of residue levels were measured by H4IIE rat hepatoma and ethoxyresorufin-O-dealkylase (EROD) bioassays....

Age-specific and lifetime reproductive success of known age Northern Spotted Owls on four study areas in Oregon and Washington

Creator:: Loschl, Peter J.
Abstract:: Northern Spotted Owls (Strix occidentalis caurina) are a long-lived forest owl and range-wide declines in their numbers have resulted in the species being listed as threatened under the endangered species act. While many studies have been focused on population trends and reproductive performance of Spotted Owls from different age-classes, none...

Vegetation characterization of three contrasting riparian areas : Williamette Valley, Oregon

Creator:: McAllister, Lynne S., Dwire, Kathleen A., and Griffith, Stephen M.
Abstract:: Much of the native riparian vegetation of the Willamette Valley, Oregon, has been replaced with agricultural crops or invasive non-native plant species. Detailed information about current Willamette Valley riparian vegetation is generally lacking. Plant specie composition data are useful in a variety of applications, including condition assessment, environmental monitoring and...

Effects of environmental stress on intertidal mussel reproduction

Creator:: Petes, Laura E.
Abstract:: Environmental stress can negatively affect the ability of organisms to reproduce. Energetic trade-offs exist in all organisms, and under stress, energy may be allocated away from reproduction and towards physiological defense and repair mechanisms. The rocky intertidal environment is ideal for investigating the influence of environmental stress, as organisms are...

Urban owners of forests in western Oregon

Creator:: Downing, Kent., Connaughton, Kent P., Hopkins, Walter S., and Oregon State University. Forest Research Laboratory
Abstract:: Urbanites who own forest land belong to a larger category of owners often referred to as small woodland owners. As a group, small woodland owners have been the subject of much investigation. Little research, however, has focused specifically on urban-dwelling owners who, as defined by the Census Bureau, live in...

Spatial and temporal patterns of fire in the forests of the central Oregon Coast Range

Creator:: Impara, Peter C.
Abstract:: Fire history and fire regime were interpreted from tree ring analysis of 4320 stumps at 178 sites in a 25 by 55 km area in the central Oregon Coast Range. A total of 27 fire episodes were identified in a 516 year period, with sizes estimated at 18 to 544...
