The wood duck is so beautiful that its scientific name, Aix sponsa, means “water bird in bridal dress.” Being so beautiful (and tasty!), by the 1880s, the once-abundant wood duck was disappearing
quickly due to hunting and habitat loss.
The California quail, Callipepla californica, is one of Americaʼs
most interesting game birds. It is easily recognizable by its loud calls
and by the clump of feathers on its head called a topknot. Over the years, this bird has been given several common names,
including California quail, valley quail,
and...
Warming of the terrestrial biosphere due to the anthropogenic addition of carbon dioxide to the earth’s atmosphere is becoming a major focus of scientific inquiry. Predictions of the extent of this warming are hampered by uncertainty in the ability of the earth’s ecosystems to counteract this effect by sequestering carbon...
These are the proceedings of a short course in the management of young Douglas-fir and western hemlock conducted by the School of Forestry, Oregon State University, June 16-18, 1969.
Upon recommendations of participants in the 1968 short course, this course was designed to enlarge upon the inventory, operational, and economic...
A central challenge for ecology is to understand the dynamic nature of species interactions. A classic approach to community ecology assumes that individuals within a species are functionally identical and that consumer-resource dynamics can be predicted solely by using species abundances. However, one species can consist of multiple functional groups,...
Bulk metallic glasses (BMGs) offer a great deal of potential through their near-theoretical strength, potentially high toughness and unique forming and molding traits. However, there are still a number of outstanding issues that bar their widespread use. This thesis describes the investigation of three research questions each designed to further...
Greater sage-grouse (Centrocercus urophasianus) populations declined range wide during the past 50 years. Grouse populations were 2-3 times larger than the current population as recently as the early 1970's. In addition to habitat loss and fragmentation, declines were attributed habitat degradation that caused reduced productivity. Because chick survival remains the...
