Nutritional ecology of millipedes in Pacific Northwest conifer forests

Creator:: Baumeister, Nancy C.
Abstract:: Comminution of forest leaf litter by millipedes affects litter decomposition and nutrient cycling. The millipede Harpaphe haydeniana Wood (Polydesmida: Xystodesmidae) is common in low to mid-elevation forests on the Pacific Coast of North America. In a series of experiments, the suitability of broadleaf and conifer tree litters for growth of...

Growth and development of spring grain species as affected by planting date

Creator:: Armah-Agyeman, Grace
Abstract:: Changes in the federal farm program, in rainfall pattern and quantity, and increased incidence of herbicide resistant weeds and diseases have generated increased interest in spring grains in the Pacific Northwest. However, spring grains have traditionally been treated as minor crops in this region, thus little research has been done...

Oceanographic effects on the dynamics of food habits and growth condition of some groundfish species of the Pacific Northwest

Creator:: Lee, Yong Woo
Abstract:: Marine fish are subject to direct and indirect oceanographic variations operating at short and long time scales. In this study feeding habits and long-term growth condition of several groundfish species of the Pacific Northwest are examined to understand the relationship between variations in the fish's biological and life history components...

Final Supplemental Environmental Impact Statement on Management of Habitat for Late-Successional and Old-Growth Forest Related Species Within the Range of the Northern Spotted Owl

Creator:: United States. Forest Service and United States. Bureau of Land Management
Abstract:: The Forest Service and the Bureau of Land Management propose to adopt coordinated ecosystem management direction for the lands they administer within the range of the northern spotted owl. This Supplemental Environmental Impact Statement (SETS) presents as alternatives the options, with slight modifications, developed by the Forest Ecosystem Management Assessment...

Feeding Ecology and Growth of Juvenile Chinook Salmon (Oncorhynchus tshawytscha) During Early Marine Residence

Creator:: Litz, Marisa Norma Chantal
Abstract:: The early marine phase following freshwater emigration has been identified as a critical period in salmonid (Oncorhynchus spp.) life history, characterized by high but variable mortality. Consistent with the “growth-mortality” and “bigger-is-better” hypotheses, at least some of the mortality during the critical period appears to be size-dependent – with smaller...

Equations for predicting height-to-crown-base, 5-year diameter-growth rate, 5-year height-growth rate, 5-year mortality rate, and maximum size-density trajectory for Douglas-fir and western hemlock in the coastal region of the Pacific Northwest

Creator:: Hann, David W., Marshall, David D., Hanus, Mark L., and Oregon State University. Forest Research Laboratory
Abstract:: Using existing permanent research plot data, we developed equations for predicting height-to-crown-base (HCB), 5-yr diametergrowth rate (delta D), 5-yr height-growth rate (delta H), 5-yr mortality rate (PM), and the maximum size-density trajectory for Douglasfir and western hemlock in the coastal region of the Pacific Northwest. With the exception of the...

Origins of the old-growth forest conflict (1971-1989) : a new model for resource allocation

Creator:: Wilson, Mark Shelton
Abstract:: The old-growth forest conflict is part of the evolving debate over how to use the federal public lands. This study documents the origins and development of the old-growth issue through 1989. The controversy began in the early 1970s when scientists initiated studies of old-growth forests and northern spotted owls, and...

Development of a hybrid modeling framework for intensively managed Douglas-fir plantations in the Pacific Northwest

Creator:: Weiskittel, Aaron R.
Abstract:: Forest growth models in the Pacific Northwest are predominantly empirical. Predictions of yield under alternative silvicultural regimes cannot rely completely on field trials; yet empirical growth models are often inadequate for extrapolating untested regimes and genotypes. The limitations of current models include (1) long time-steps (e.g. 5-10 years); (2) insufficient...
