Methodology to predict the strength and stiffness of red alder block pallet connections fastened with helically threaded nails
… is to develop a methodology to measure and predict the strength and the stiffness of red alder (Alnus rubra) nailed pallet connections subjected to repetitive loading. Joint tests were conducted to define the mechanical properties of bottom block pallet connections. The primary tests were …

Physiological and Morphological Responses of Nitrogen-Fixing Red Alder (Alnus Rubra) and Sitka Alder (Alnus Viridis Ssp. Sinuata) to Flooding: Inter- and Intraspecific Comparisons
Red alder (Alnus rubra) and sitka alder (A. viridis ssp. sinuata) are nitrogen-fixing woody species that grow sympatrically along the Pacific coast of North America. Red alder is found in poorly drained lowlands, as well as in soils of moist upland slopes, whereas sitka alder generally colonizes …

Impact of Gap Size on Environmental Conditions, Survival, and Early Growth of 5 Pacific Northwest Species
… mortality was significantly higher than western redcedar (5.0%), red alder (6.9%), and grand fir (8.1%) mortality. Chlorophyll fluorescence tracked over summer drought months suggested that as soils became drier, seedling health improved for all species. Environmental predictors of growth …

Breeding territory settlement patterns and mate choice in a monochromatic tyrannid flycatcher
… along a habitat-quality gradient defined by red alder (Alnus ruba) and preferred nesting substrate (adventitious nest substrate) densities. Early arriving adult males excluded later arriving males, including yearling males, from gaining access to high-quality habitat. Acquisition of …

Detecting Change in Central California Coast Coho Salmon Habitat in Scotts Creek, California, from 1997–2013
… due to increases in hard-wood species (i.e., red alder [<em>Alnus rubra</em>] and California bay [<em>Umbellularia californica</em>]). When compared to habitat goals established in the federal CCC Coho Salmon Recovery Plan, Scotts Creek has adequate canopy cover and percentage pools, but is …
