Abstract Native salmonid fishes—cutthroat trout ( Oncorhynchus clarkii ) and steelhead/rainbow mykiss )—are ecologically, culturally, economically important species distributed across western North America. These fish are generally considered “cold‐water” adapted species. As such, recent studies have speculated about the potential effects of climate change on these native salmonids if stream temperature thresholds exceed 16–20°C during summer. However, magnitude thermal responses to slow but...
Abstract In contemporary forest management, buffers of unharvested trees are left along streams to protect riparian and aquatic ecosystems. Buffer regulations often focus on specific minimum width requirements, which aid in straightforward regulation application, but widths also suggest buffered edges uniform contain little variability. Conceptual papers that alternative buffer configurations may offer greater flexibility landscape-level protection, increase complexity, enhance biodiversity....
Wildfire has become increasingly common and severe across forested landscapes. Shortly after wildfire, loss of riparian cover along streams subsequent increases in light can elevate stream temperatures, a key control on metabolic rates biota. Increased also increase autotrophic basal resource availability with potential bottom-up effects. We evaluated wildfire impacts aquatic ecosystems replicated Before-After Control-Impact study 1 year western Oregon, U.S. Stream temperature, chlorophyll...
Wildfire has become increasingly common and severe in forested landscapes across the western United States. Stream air temperatures within these are influenced not only by direct heating during fire but shading from heavy smoke. In addition, dissolved oxygen (DO) can be affected increased ash inputs or reduced primary production under lower light conditions. Because collecting data as event occurs is challenging, most research exploring effects on streams focused responses months to years...
Many headwaters across temperate North America have uniform mid‐succession riparian forests recovering from historic land clearing. These young stands contrast with late‐succession forests, which complex structural characteristics including canopy gaps. Canopy gaps provide diversity that can be important for terrestrial species, and they are also hypothesized to features aquatic environments. The light patches below create productivity hotspots in streams therefore potential increased stream...
Abstract Objective This study explored changes in the self-conscious emotions of shame, guilt, and pride adults with brain injuries after experiencing an intervention encouraging them to communicate their loved ones about recovery experiences. Method Adults acquired (mean age 49.5; 70% female; 3 yrs post) attended a presentation regarding importance communication during were asked discuss Seven participants completed State Shame & Guilt Scale pre- post-intervention, 8 ratings comfort...
This study was designed to assess effects of posttraumatic growth (PTG) on ratings current and predicted future functioning in adults with moderate-severe traumatic brain injury (mod-sev TBI) their family members.Fifteen mod-sev TBI (age 34.5; 4.1 yrs post), a member for each, rated current, 2-3-year future, satisfaction physical, cognitive, emotional recovery. All participants also completed the Neurobehavioral Functioning Inventory, patients Motivation Rehabilitation Questionnaire. PTG...
