Hawai’i’s economy is 2 dimensional, relying both on agricultural products and tourism. In order for the state to have a more sustainable economy it’s going to need multiple sources of revenues and not rely primarily on one. Currently there is no successful model of timber harvesting in Hawaii. Developing a...
Wetland habitats are disappearing at an alarming rate and research is finding that establishment and creation of wetland habitat is generally unsuccessful. Typical mitigation strategies in the past have created multiple small isolated wetlands with little functioning habitat. Within Washington State, guidance and research recommends utilizing mitigation banks to compensate...
Prescribed burning is increasingly being used as a management tool to reduce potential fuels on the forest floor and promote stand vigor through removal of dense, crowded vegetation. Because fire affects both the standing vegetation and the amount of downed wood in the ecosystem, it is imperative to examine how...
The specific habitat requirements of harlequin ducks (Histrionicus histrionicus
Linnaeus 1758), which breed in the Pacific Northwest, are largely unknown. I captured
and attached radio transmitters to 42 female harlequins (36 paired and 6 unpaired) in the
central Cascade Range of Oregon in 1994 and 1995. Breeding pairs used 3rd...
Riparian zones provide habitat for breeding birds in the semiarid western United States; however, there are few data available that address the effects of livestock grazing strategies on riparian habitats and avian communities. Documenting avian community composition in different riparian vegetation communities and relating vegetation communities to livestock grazing strategies...
I evaluated the response of the federally listed endangered plant species Bradshaw's desert parsley (Lomatium bradshawii) to livestock grazing and small mammal depredation at Oak Creek, Linn County, Oregon, 1997-1998. I established six study blocks (three each in wooded and herbaceous pastures) with plots in each block randomly assigned to...
The Chugach National Forest has been using prescribed fire as a wildlife habitat management tool since l977. Between 1977 and 1997 about 4,000 hectares have been burned on the Kenai Peninsula to promote regeneration of woody plant species used by moose (Alces alces). Browse species include paper birch (Betula papyrifera),...
The major purpose of this research was to characterize partially degraded proteins
appearing in the ocular lens during aging and cataract, and to identify the responsible
proteolytic activities. This research is significant, because increased protein
degradation is associated with lens opacification and cataract. Determining the sites
where lens proteins become...
This investigation on fire mosaics addressed several aspects:
(1) quantifying the role of terrain variables in fire-related
mortality and historical mean fire return interval (MFRI), (2)
comparing post-burn Landsat Thematic Mapper (TM) imagery, TM
difference imagery, and aerial photo interpretation to map forest
survival after wildfire, and (3) to describe...
