Rhizopogon is a large genus of ectomycorrhizal (EM) fungi that grows in association with host trees of the family Pinaceae. We have conducted a series of studies investigating the ecology and evolutionary biology of the EM symbiosis shared between R. subgenus Villosuli and trees of the genus Pseudotsuga. Two members...
Soils contain the largest pool of carbon that is actively cycling on human timescales, leading many to view soils as a natural climate solution with multiple co-benefits. The field of soil science is rapidly evolving, but without a unified understanding of soil carbon dynamics. This dissertation leverages two distinct long-term...
The goal of the study was to collect data on the ecology and
reproduction of Sophora leachiana in order to help explain the rarity
and restricted range of this species. There are 13 known populations
of S. leachiana, occurring in a 29 by 6.4 km area in the Siskiyou
Mountains...
Fifty species and subspecies and six varieties in eight genera of
the family Tabanidae are recognized from Oregon. The following genera
are represented in Oregon: Apatolestes Williston, Pilimas Brennan,
Stonemyia Brennan, Silvius Meigen, Chrysops Meigen, Atylotus Osten
Sacken, Hybomitra Enderlein and Tabanus Linnaeus. Adults and larvae
were collected from various...
Small commercial and non-commercial animal enterprises (SCAEs) raise a few
beef cows, horses, pigs, sheep, poultry, and other animals on a few acres. These
enterprises are often located in suburban areas of watersheds and show potential for
degrading water quality through to increased bacterial, nitrogen, and phosphorus
concentrations. SCAEs implement...

Summarizes information on wood as an engineering material.
Presents properties of wood and wood-based products
of particular concern to the architect and engineer. Includes
discussion of designing with wood and wood-based products
along with some pertinent uses.
The objectives of this guide are to provide information to allow users to be able to identify potential natural vegetation types in wetlands (and transitional riparian areas) and to provide information pertinent to the use and management of these
areas. An attempt has been made to describe the successional status...
