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 …

Monitoring the influx of marine derived Nitrogen and characterizing soil food webs of riparian zones of the Elwha River Watershed, WA, USA.
… salmon and symbiotic nitrogen fixation via Alnus rubra. The recent removal of two large dams on the Elwha River, WA, opened up ~60 km of previously inaccessible river habitat for pacific salmon. I used naturally abundant stable nitrogen isotopes (denoted as ‰ δ15N) to establish baseline data …

Methodology to predict the strength and stiffness of red alder block pallet connections fastened with helically threaded nails
… 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 conducted to define the strength and stiffness of joint …

Filler effects in resole adhesive formulations
… from walnut shell (Juglans regia), alder bark (Alnus rubra), almond shell (Prunus dulcis), and corn cob (furfural production) residue. The chemical composition of all fillers was measured and compared to published data. The basic rheological behavior of the formulations was determined and used …

Detecting Change in Central California Coast Coho Salmon Habitat in Scotts Creek, California, from 1997–2013
… 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 lacking in …

Organic Fillers in Phenol-Formaldehyde Wood Adhesives
… from walnut shell (Juglans regia), alder bark (Alnus rubra), and corn cob (furfural production) residue. Alder bark and walnut shell exhibited chemical compositions that are typical for lignocellulosic materials, whereas corn cob residue was distinctly different owing to the high pressure steam …

Impact of Gap Size on Environmental Conditions, Survival, and Early Growth of 5 Pacific Northwest Species
… coverage where growth then decreased. Red alder (Alnus rubra), western redcedar, and western hemlock were significantly impacted by ungulate browse which occurred in half of western redcedar and red alder seedlings. Western redcedar saw an increase in basal area increment in response to browse …

Evaluation of Red Alder Mortality in the Little Creek Watershed Following the 2009 Lockheed Fire
<p>Five hundred eighty red alder along a 2.16 km portion of the Little Creek riparian zone were assessed for mortality following the 2009 Lockheed Fire near Davenport, California. The study area was divided into burn severity zones and every red alder within the riparian zone was observed and …
