Magnetic materials can be used in modern soft robotics as a method for external stimulus actuation and motion control. By combining aspects of biology and mechanics, devices are fabricated to create a structure capable of complex movement. Applications that these devices are subject to can be broken down into four...
Netarts Bay is a shallow, temperate, tidal lagoon located on the northern coast of Oregon and site of the Whiskey Creek Shellfish Hatchery (WCSH). Data collected with an automated flow-through system installed at WCSH capable of high-resolution (1 Hz) pCO2 and hourly TCO2 measurements, with measurement uncertainties of <2.0% and...
Contemporary fire effects are raising concerns about the resistance and resilience of dry mixed-conifer forests to large wildfires. Fire refugia – unburned or low-severity patches within fire perimeters – are understudied components of post-fire mosaics that may be key drivers of forest recovery following high-severity fire. Little is known about...
Reduction of stratospheric ozone caused by human
perturbation with halocarbon compounds and the consequent
increase in mid-wavelength ultraviolet radiation (UV-B
radiation. 290-320 nm) reaching the earth's surface could
have deleterious ecological effects on marine primary
producers. Unialgal and mixed cultures of Thalassiosira
pseudonana and Thalassiosira weisflogii were exposed to
three...
With increased attention being focused on the remaining old-growth
forest resource in the Pacific Northwest a way to ecologically rate forest stands is
needed to assist the U.S. Forest Service in its management decisions. A Geographic
Information System (GIS) model was developed to rate old-growth stands in a 49,500
acre...
This investigation identifies one pathway by which domestic violence increases the potential for child abuse in both mothers and fathers of newborns. Longitudinal data from 181 couples with firstborn infants were used to test a mediational model linking domestic violence and the family's risk of child abuse. Analysis of covariance...
State parks in Oregon provide important sites for visitor recreation and natural resource education. With the increasing number of visitors to Oregon coastal parks, tide pools and beach areas, there is growing need for site-specific marine education to enhance stewardship, interpretation and safety knowledge. The Oregon Sea Grant Program and...
