Douglas-fir and grand fir seedling establishment and plant community regeneration were examined in a western Oregon forest following harvest in three
different silvicultural systems: clearcut, two-story and patchcut. The two-story system
consisted of removing all but 10 to 12 trees per acre. The patchcut system consisted of
harvesting 1/2 acre...
A crossdated fire history was reconstructed for a 1562 km2 area in the southern Willamette foothills of Oregon, using fire scars and tree origin years from twelve sites. The purpose of this study was to determine fire frequency for each site and to quantify temporal and spatial variability of fire...
Salal is plant species that is native to forestland throughout the PNW and northern California that has been identified as a competitor to early crop tree development. This study consisted of a field and a radioisotope laboratory study to test four commonly used herbicides on salal (imazapyr, triclopyr, glyphosate, and...
AIM: C₄ photosynthesis is an adaptation that maintains efficient carbon assimilation in warm and low-CO₂ conditions. Due to the importance of C₄ grasses for carbon and surface energy fluxes numerous models have been proposed to describe their spatial distribution and forecast responses to climate change. These models often rely on...
Home range and habitat use by pileated woodpeckers
(Dryocopus pileatus) were studied in the Coast Ranges of western
Oregon. Radio-telemetry was used to determine home ranges of 11
woodpeckers and habitat use of 14 woodpeckers after young had
fledged during summers from 1982 to 1985. Home range size for
individual...

Phospholipase C-β (PLC-β) isozymes are key effectors in G protein-coupled
signaling pathways. Prior research suggested that some isoforms of PLC-β may exist
and function as dimers, but little is known about dimerization of PLC-β. Data from coimmunoprecipitation
assays of differentially-tagged PLC-β constructs and sizeexclusion
chromatography of native PLC-β support homodimerization...
