Aniba rosaeodora commonly known as rosewood is a tree species of great socio-economic value in the Amazon because it is harvested for the extraction of its essential oil, which is used in the production of cosmetics. Since rosewood is a wild species included on the Convention on International Trade in...
Competition for soil water resources between newly planted Douglas-fir seedlings and aggressive early-seral plants, such as Senecio sylvaticus [L.] (Woodland groundsel, Senecio), can create drought conditions that impact tree seedling physiology, growth and likelihood of mortality. However, the specific impact of Senecio on soil moisture dynamics and inducement of water...
Throughout Oregon State University, a permanent, publicly-owned art collection not only exists under the radar of most people's awareness, this collection is part of a state mandate in existence since the late 1970's and too manages to slip most people's awareness at all. It is the Percent for Art Collection,...
Provides information about complexity of watersheds. Outlines ways to form partnerships, to develop strategies for enhancing watershed resources, and to implement enhancement projects.
In the Northwest, two tree fruit production problems may be
related to the role of ethylene on plant growth and development:
flowers and developing fruits are subject to low temperature injury
during early spring, and to the low fruit set of 'Comice'. Ethylene
may be involved in influencing dormancy and...
Major and trace element analyses were made on biogenic carbonate,
silica, and fish debris and on authigenic philhipsite, micronodules, and
yellow and brown aggregates recovered from Bauer and Roggeveen Basin
metalliferous sediments. Phase components and the bulk samples were
analyzed by INAA and MS methods. Leachates and residues from ammonium...
Experiments were conducted to determine the effect of rumen
fluid on live and motile spermatozoa of semen extended in yolk-citrate
and stored at 4°C. Preliminary work showed that levels of
rumen fluid below 10 percent were beneficial in keeping spermatozoan
activity up to 14 days in storage. For more revealing...
