A phenological examination of terrestrial invertebrate abundance at H. J. Andrews Experimental Forest, Oregon

Creator:: Mackereth, Kailan F.
Abstract:: Abstract Understanding the effects of climate change on forest ecosystems requires exploration of the relationships of different components of the system, such as the response of biota to local hydrology, temperature, precipitation, and elevation. The Long-term Ecological Research Program at the H. J. Andrews Experimental Forest, located in the Western...

A spatially explicit model for allocating conservation efforts : the Grand Ronde River basin, Oregon

Creator:: Watanabe, Michio
Abstract:: The spatial and dynamic pattern of landscape changes has a profound effect on the supply of environmental services, including the provision of habitat for fish and wildlife. Spatial heterogeneity is a common feature of landscapes in the Pacific Northwest, most notably in areas important to the production of salmonid fish...

A study of stream temperature using distributed temperature sensing fiber optics technology in Big Boulder Creek, a tributary to the Middle Fork John Day River in eastern Oregon

Creator:: Arik, Aida D.
Abstract:: The Middle Fork John Day Basin in Northeastern Oregon is prime habitat for spring Chinook salmon and Steelhead trout. In 2008, a major tributary supporting rearing habitat, Big Boulder Creek, was restored to its historic mid-valley channel along a 1 km stretch of stream 800 m upstream of the mouth....

An assessment of southern Oregon clearcut and shelterwood cut cover types using LANDSAT MSS digital and supporting aircraft data

Creator:: Hawley, David Llewellyn
Abstract:: The feasibility of utilizing LANDSAT MSS data in assessing surface cover types and areal extent of clearcut and shelterwood cut harvest sites in southern Oregon was investigated. The research utilized extensive 'ground truth' information to evaluate the LANDSAT data. A three faceted ground truth collection scheme analyzed 1) U.S. Forest...

An evaluation of temperature prediction models on Coastal Oregon and western Cascade streams

Creator:: Tanner, Robert W.
Abstract:: Evaluations were performed on three stream temperature prediction models: Heat Source 5.6, SSTEMP 3.9, and Brown's equation. Each model was evaluated using data collected from three Coastal Oregon and two western Cascade streams. Stream temperature simulations were performed on two forested reaches, one clearcut reach, and one buffered reach, for...

Ascospore viability and dispersal from pruned branches infected with Anisogramma anomala

Creator:: Heckert, Stephanie
Abstract:: Viability and dispersal of ascospores of Anisogramma anomala, the cause of eastern filbert blight (EFB) on European hazelnut, from diseased branches pruned from trees were measured. In each of two years, branches bearing stromata of A. anomala were cut in mid-December and compared to branches cut near budbreak in March,...

Biogeochemical signals of mountainous forested watersheds' response to disturbance

Creator:: Guerrero-Bolaño Francisco J.
Abstract:: Small mountainous watersheds are disproportionate sources of land-derived particulate organic matter (POM) to long-term sinks like lake bottoms and the ocean. As such, these ecosystems are an essential component of the global carbon cycle. The burial of POM in lacustrine and marine sediments contributes to the drawdown of atmospheric CO2...

Bottom-up Drivers of Primary Producers and Predator Populations in Oregon Streams

Creator:: Kaylor, Matthew J.
Abstract:: Humans have drastically altered the physical habitat and food web structure of stream ecosystems. Two major impacts humans have had on Pacific Northwest streams are modification of streamside forests (as a result of agriculture, land development, and timber harvest), and declines in the return of wild anadromous salmon to headwater...

Buzzing Bolbomyiidae and Air Temperature Monitoring Methods: Investigating Long-Term Ecological Data from the H.J. Andrews Experimental Forest

Creator:: Schmidt, Stephanie A.
Abstract:: The short-term duration of most ecological studies can make it difficult to capture the long-term dynamics of ecosystems and populations. Infrequent or high-impact events can be missed, or erroneously documented as baselines. Long-term ecological research enables a deeper understanding of complex processes, provides a foundation for future insights, and can...

California condors in the Pacific Northwest : integrating history, molecular ecology, and spatial modeling for reintroduction planning

Creator:: D'Elia, Jesse
Abstract:: Reintroduction programs are increasingly being used to save animals from extinction and aid in their recovery. The California Condor (Gymnogyps californianus), one of the most endangered birds in the world, is a remarkable example of how reintroduction programs can help rapidly increase a species' population numbers and range following a...
