The analysis of prehistoric stone features has suffered for two separate but related reasons. The first is the lack of stringency in defining the terms attributed to these structures and, second, the perception of a lack of formal attributes exhibited by them. These two factors have made it impossible to...
In Oregon, the effects of climate change on agriculture are already being felt. In the Northwest, climate change impacts agricultural pest pressure, especially insects, whose life cycles are tied directly to weather and climate. The goal of this research was to record and analyze Oregon fruit and vegetable farmers’ relationships...
Aspects of the life history and ecology of the intertidal turf-forming
alga Rhodomela larix (Turner) C. Agardh were examined over a two
year period at several sites on the Oregon coast. Rhodomela occurred
over a broad tidal range and exhibited different growth and morphology
characteristics with respect to tidal height....
The critically endangered Maui's dolphin (Cephalorhynchus hectori maui) and the endangered Hector's dolphin (C. h. hectori) are endemic to the coastal waters of New Zealand, where their primary threat is fisheries-related mortality. The Maui's dolphin is among the most critically endangered cetaceans in the world, with its remnant population primarily...
The climate of the Pacific Northwest is in flux, and existing forest ecosystems are stressed and poised to shift in fundamental ways, with or without human intervention. This dissertation probes the nature of forest responses to environmental change through investigations of morphology and genetics of three species of alder co-occurring...
We compared three existing ecoregional classification schemes (Bailey, Omernik, and World Wildlife Fund) with two derived schemes (Omernik Revised and Climate Zones) to explore their effectiveness in explaining species distributions and to better understand natural resource geography in the Klamath Region, USA. We analyzed presence/absence data derived from digital distribution...
