Environmental DNA (eDNA) detection of aquatic invasive species is at the forefront of aquatic conservation efforts because of decreased costs, increased response times, and increase of sensitivity for intercepting invasions with low density populations. Developments in eDNA technologies have improved detection probabilities for rare, indicator, and invasive species over the...
A new species of Dryophthorus (Coleoptera:Dryophthoridae) and two new species of Stenommatus (Coleoptera:Dryophthoridae) are described from Dominican amber. D. microtremus n. sp. is characterized by monochrome dorsal scales, nearly parallel sides of the pronotum, wide elytral intervals and the elytral apex only slightly narrowed. S. tanyrhinus n. sp. is characterized...
Checking was influenced b drying conditions. This influence was greatest before average moisture content reached 20 per cent, but tension in surface layers caused checking even below this point.
Neither high initial dry-bulb temperature nor initial conditions of high equilibrium moisture content were conducive to checking.
High temperature and high...
The Oregon Forest Products Laboratory was asked in July 1953 by the Oregon Alder and Maple Company, Willamina, to work on the problem of dark stain which developed at sticker crossings in air-drying red alder (Alnus rubra, Bong.) during the summer months.
Previous experience at the Oregon Alder and Maple...
The increasing volume of young-growth Douglas-fir timber cut in the Pacific Northwest emphasizes the need for more knowledge on the characteristics of lumber sawed from these trees.
The study described here was initiated to learn the extent arid causes of degrade resulting from kiln-drying young-growth Douglas-fir dimension lumber. At the...
