In the late 1950s, "two California men" came to Oregon to learn if there were abalone here, and found them in the southern part of the state. The resulting publicity and interest inspired this document, an attempt to develop regulations for a new fishery. It is an internal discussion paper...
‘Lewis’ is a hazelnut cultivar developed by Oregon State University and released in January 1997. This cultivar is precocious, and it is more productive and has a smaller tree size than ‘Barcelona.’ Harvest is earlier than for ‘Barcelona,’ and the nuts have fewer defects.
The Lewis and Clark journals contain some of the earliest and most detailed written descriptions of a large part of the United States before
Euro-American settlement.We used the journal entries to assess the influence of humans on wildlife distribution and abundance. Areas with
denser human population, such as the Columbia...
Fire suppression has increased fuel loads and fuel continuity in mixed-conifer ecosystems, resulting in forest structures
that are vulnerable to catastrophic fire. This paper models fire behaviour in a mixed-conifer forest and investigates how
silvicultural and fuels treatments affect potential fire behaviour. The computer program FARSITE was used to spatially...
A study to review the status and distribution of vascular plants at Lewis and Clark National Historical Park was initiated in 2009 and completed in 2010 by the Oregon Natural Heritage Information Center at Oregon State University. This study built on previous inventories conducted under the National Park Service‘s Inventory...
The distribution and geographic range of Greater Sage-Grouse (Centrocercus urophasianus) have been reduced by 56% since European settlement. Although loss and fragmentation of sagebrush (Artemisia spp.) habitats have been cited as the primary causes for the decline of the species, degradation of existing habitat also has been considered an important...
Declines in Greater Sage-Grouse (Centrocercus urophasianus, hereafter sage-grouse) populations could be attributed to low chick survival, which may be influenced by the availability of food and cover at sites used by females rearing broods. Habitat attributes important to broods may vary regionally; thus, it is necessary to understand factors affecting...
The small S₁ ocean tide is caused primarily by diurnal atmospheric pressure loading. Its excitation is therefore unlike any other diurnal tide; in particular, pressure loading is maximum near the equator where the diurnal gravitational potential is zero. The global character of the S₁ tide is here determined by numerical...
Movement in an important component of an animal’s life cycle when it relies on both aquatic and terrestrial habitats. When multiple species overlap in the use of these habitats, they rely on other methods to reduce competition for shared resources. This dataset measured the jumping performance and movement behavior of...
