Watershed-level patterns among stream amphibians in the Blue River watershed, West-Central Cascades of Oregon

Creator:

Hunter, Matthew G.

Abstract:

Most recent research on stream amphibians in the Pacific Northwest has focused on associations with reach-level or stand-level environmental features. Little is known about landscape-level distributions of these species or landscape-level aspects of their life-histories. I used a watershed-wide sample and logistic regression to develop models and maps of probability...

Composition, structure, and biomass of cottonwood-dominated gallery forests along a successional gradient, Willamette River, Oregon

Creator:

Fierke, Melissa K.

Abstract:

Recognizing the importance of native black cottonwood-dominated riparian forests is especially important to preserve, protect, and manage for biodiversity in the Willamette River Valley. Species composition, structure, and biomass along a successional gradient from stand initiation to late succession of black cottonwood (Populus balsamfera L. subsp. trichocarpa (T. & G.)...

Spatial and temporal characteristics of groundwater levels adjacent to beaver ponds in Oregon

Creator:

Sharps, Diana E.

Abstract:

This study was undertaken to evaluate the spatial and temporal characteristics of riparian groundwater tables adjacent to beaver ponds. The research was conducted in two parts; in the first portion a two-dimensional, finite-difference computer model was developed and utilized to simulate groundwater elevations through time in pond-adjacent aquifers. Two types...
