Movement and demography of larval coastal giant salamanders (Dicamptodon tenebrosus) in streams with culverts in the Oregon Coast Range

Creator:

Sagar, Jina P.

Abstract:

Barriers to the movement of aquatic organisms can increase the genetic and spatial isolation of populations and may decrease the viability of these regional populations. Focus on culvert passage issues has increased as federal agencies attempt to inventory and replace road-crossing stream culverts that are barriers to the movement of...

Experimental analysis of intra- and interspecific competitive interactions between cutthroat trout and sculpins in small streams

Creator:

Ramirez, Ben S.

Abstract:

In the Pacific Northwest ecoregion of North America, sculpins represent a major constituent of freshwater assemblages in coastal rivers. Based on their prevalence and abundance, sculpins are likely important ecologically, yet little is known of their interactions with co-occurring species, such as widely studied salmon and trout (salmonines). In this...

Contributions of riparian vegetation and stream morphology to headwater stream temperature patterns in the Oregon Coast Range

Creator:

Smith, Danielle D.

Abstract:

The role of riparian forests in maintaining temperatures of headwater streams is well established and is a foundation of forest practice rules designed to protect streamwater quality. However, detailed investigation is still needed quantifying specific characteristics of stream systems that affect streamwater temperature including riparian features, stream morphology, and subsurface...

Fall directions and breakage of riparian trees along streams in the Pacific Northwest

Creator:

Sobota, Daniel J.

Abstract:

In the Pacific Northwest, regulatory agencies have recently implemented management strategies for restoration and maintenance of wood recruitment to streams over time. This allochthonous organic material is a critical component in the geomorphic and biological structure of forested streams. Mathematical models are commonly used to evaluate long-term wood dynamics in...

Determination of Trade-offs between Wetland Ecosystem Services in an Agricultural Landscape

Creator:

Garrison, Stacey L.

Abstract:

Wetland restoration mitigates effects of agricultural development on water quality, flooding, and habitat loss. Multi-objective optimization for wetland locations and sizes has not included objective functions for water quality, hydrology, and habitat in unison, limiting analysis of trade-offs among these ecosystem services. This study establishes two methods to improve the...

Headwater stream characterization : an energy and physical approach to stream temperature using distributed temperature sensing

Creator:

Roth, Travis R.

Abstract:

Headwater streams are an integral part of the ecological health of the greater stream network as they provide valuable biological habitat, provide upwards to 95% of total in channel flow, while providing downstream reaches with important constituents such as sediment and woody debris. Small headwater streams are particularly susceptible to...

Examining effectiveness of Oregon’s forest practice rules for maintaining warm-season maximum stream temperature patterns in the Oregon Coast Range

Creator:

Fleuret, Jennifer Marie

Abstract:

Stream temperature, as an important component of stream ecosystems, can be affected by forest harvesting through removal of riparian shade and changes in hydrology. Riparian Management Areas (RMAs), as implemented through the current Oregon Forest Practice Rules, are designed, in part, to maintain stream temperature following forest harvesting. However, effectiveness...

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....

Influences of Thermal and Trophic Heterogeneity on Phenology, Growth, and Resource Use by Juvenile Coho Salmon

Creator:

Campbell, Emily Y.

Abstract:

Ecological resources available to freshwater fish shift spatially, temporally and across life stages. To better understand how spatial-temporal availability of resources influence fish, I examined the phenologies of hatching and emergence of Coho Salmon (Oncorhynchus kisutch) in streams with contrasting and strongly defined seasonal thermal variability. The study streams included...

New insights on an old topic : understanding the effects of forest harvest on trout in the context of climate

Creator:

Penaluna, Brooke E.

Abstract:

Studies of the effects of forest harvest on streams and fish have a long history in the Pacific Northwest. Results of this work have prompted development of new forest harvest practices that are more protective of these resources, but the effectiveness of these new practices has not been fully evaluated....
