Influences of clearcut logging on macroinvertebrates in perennial and intermittent headwaters of the Central Oregon Coast Range

Creator:: Banks, Janel
Abstract:: This research was designed to broaden the understanding of how timber-harvest affects aquatic macroinvertebrates in perennial and intermittent headwater streams. This study compared emergent and benthic macroinvertebrate assemblages from 20 headwater streams in the central Oregon Coast Range that varied by harvest condition and flow duration. Through comparison of the...

Headwater stream macroinvertebrates of the H.J. Andrews Experimental Forest, Oregon

Creator:: Frady, Charles H.
Abstract:: Recent studies of headwater streams have demonstrated their importance to overall watershed biodiversity, nutrient cycling, and energy flux. However, little attention has been paid to long-term effects of forest harvest on macroinvertebrate communities in headwater streams. This study investigated headwater stream macroinvertebrate communities in the H.J. Andrews Experimental Forest, Oregon,...

Structure-forming benthic invertebrates : habitat distributions on the continental margin of Oregon and Washington

Creator:: Strom, Natalie A.
Abstract:: Structure-forming invertebrates belong to a polyphyletic group of primarily sessile and sedentary megafauna that can significantly enhance the complexity of physical habitats. A number of these organisms, including cold-water corals and sponges, are known to be slow growing and vulnerable to physical disturbance. In addition, as filter feeders, these invertebrates...

Effects of forest management on fish habitat and macroinvertebrates in northeast Oregon streams

Creator:: Carlson, Joan Y.
Abstract:: This study describes streams in the Blue Mountains and Wallowa Mountains of Northeastern Oregon in order to characterize the interactions between the terrestrial and aquatic ecosystems and to determine how logging affects those relationships. Five stream reach pairs, each consisting of an undisturbed reach and a similar reach flowing through...

Associations of forest floor vertebrates with coarse woody debris in managed forests, western Oregon Cascades

Creator:: Butts, Sally R.
Abstract:: Forest floor vertebrate species presence and abundance may be influenced by the volume and cover of coarse woody debris (CWD) in managed forests. I studied macro- and microhabitat associations of vertebrate species in 18 closed-canopy stands ranging in CWD volume from 14 to 859 m3/ha. Pitfall traps were used to...

Surfgrasses (Phyllospadix spp.) as dynamic foundation species for macroinvertebrates along the Oregon coast

Creator:: Moulton, Orissa M.
Abstract:: Foundation species are important components of ecosystems because they provide habitat and ameliorate stressful conditions for residents. This thesis considers the role of surfgrasses (Phyllospadix spp.) as dynamic foundation species on the coast of Oregon in two studies. Chapter 2, which presents an observational survey of two Phyllospadix congeners, investigates...

Habitat mapping and identifying suitable habitat of Redfish Rocks Pilot Marine Reserve, Port Orford, Oregon

Creator:: Amolo, Rizaller C.
Abstract:: Establishment of marine protected areas (MPAs) has been documented to effectively manage marine resource's diversity and enhance fisheries productivity. However, there must be a critical consideration of how these sites are selected and the actual description of the site itself. Its effectiveness is greatly dependent on understanding these habitats and...

Patterns of benthic macroinvertebrate communities and habitat associations in temperate continental shelf waters of the Pacific Northwest

Creator:: Lee, Timothy Seung-chul
Abstract:: Macroinvertebrates constitute the backbone of megafaunal communities in benthic ecosystems around the globe. Many macroinvertebrates have vital roles in benthic ecosystems, ranging from enhancing habitat complexity to providing staple food sources for other organisms. Regardless of how familiar macroinvertebrates are to the general public, very few studies have attempted to...

Lotic macroinvertebrate distribution patterns in northeastern Oregon

Creator:: Gerth, William J.
Abstract:: This study was an investigation of lotic macroinvertebrate distribution in northeastern Oregon at two different spatial and biological scales. Examination of assemblages at a limited spatial scale revealed relationships with natural and disturbance gradients and led to questions about distribution of a population at broader spatial scales. In a 16...

Habitat suitability and uncertainty : a Bayesian approach to mapping benthic invertebrate distributions

Creator:: Havron, Andrea M.
Abstract:: Mitigating for increased human impact to the seafloor associated with resource extraction activities and renewable energy development can benefit from an understanding of the distribution of sensitive marine benthic species. Habitat suitability predictive modeling is a cost effective statistical tool to infer species distribution patterns from constrained sampling locations. However,...
