Global amphibian declines have been attributed to numerous and often synergistic causes, such as invasive species, pathogens, and ultraviolet-B (UV-B) radiation. The effects of these stressors are context dependent and can vary with location, species, and populations. As sensitivity to UV-B has shown inconsistencies across amphibian taxa, it can be...
Wetland restoration success in attaining wildlife conservation goals can be confounded by the presence of multiple biological invaders. Wetland management activities typically target invasive plants, but bottom-up responses of higher trophic levels in novel communities are difficult to predict. We surveyed plant and amphibian assemblages at 26 sites enrolled in...
Little is known on the importance of riparian areas to birds near small headwater streams in mesic forests. Progress towards understanding limiting factors that affect bird populations has been difficult because of lack of information beyond the breeding period. I compared bird assemblages between headwater riparian and upland areas throughout...
Confluence is a newsletter of Oregon Sea Grant promoting discovery, understanding, and resilience for Oregon coastal communities and ecosystems. Articles feature the supported research and events of the program.
This report is for companies along the Oregon Coast that provide guided kayaking, salmon fishing, and whale-watching tours. It aims to help them better understand the effectiveness of their online marketing and see how their prices compare to those of their competitors.
An exhibit on display at Oregon State University’s Hatfield Marine Science Visitor Center in Newport, Oregon. Lists some of the responsibilities and costs of buying, setting up, and maintaining a freshwater aquarium.

This issue of Confluence includes articles on: potential of farming gooseneck barnacles, educating boaters on proper waste disposal, Dungeness crab genetics study, how to reduce injuries for crabbers at sea, women's changing...
This five-lesson curriculum seeks to increase students' understanding of ocean acidification (OA) and help them understand that it is an issue they can address. There are five lessons in the unit and a final Call to Action project.
Lesson 1 explores a real-life story about the near collapse of the...
Biological invasion potential can be strongly influenced by abiotic factors such as temperature, water availability, and solar radiation. Invasive species that possess phenotypically plastic traits can mediate impacts from these stressors, but may be unable to recognize and respond to dangerous levels in a novel environment. Understanding potential constraints on...
