Invertebrate composition and distribution in desert springs of Oregon

Creator:: Mauger, Susan
Abstract:: In the summers of 1998 and 1999, aquatic invertebrate and plant communities were sampled from nineteen springs in the Warner Basin of southeastern Oregon. Across the landscape, these springs exhibited a broad range in water temperature (5-24°C), pH, conductivity, elevation, and gradient. Within a particular spring, water temperature and chemistry...

Structure-forming benthic invertebrates : habitat distributions on the continental margin of Oregon and Washington

Creator:: Strom, Natalie A.
Abstract:: Structure-forming invertebrates belong to a polyphyletic group of primarily sessile and sedentary megafauna that can significantly enhance the complexity of physical habitats. A number of these organisms, including cold-water corals and sponges, are known to be slow growing and vulnerable to physical disturbance. In addition, as filter feeders, these invertebrates...

Influences of clearcut logging on macroinvertebrates in perennial and intermittent headwaters of the Central Oregon Coast Range

Creator:: Banks, Janel
Abstract:: This research was designed to broaden the understanding of how timber-harvest affects aquatic macroinvertebrates in perennial and intermittent headwater streams. This study compared emergent and benthic macroinvertebrate assemblages from 20 headwater streams in the central Oregon Coast Range that varied by harvest condition and flow duration. Through comparison of the...

Headwater stream macroinvertebrates of the H.J. Andrews Experimental Forest, Oregon

Creator:: Frady, Charles H.
Abstract:: Recent studies of headwater streams have demonstrated their importance to overall watershed biodiversity, nutrient cycling, and energy flux. However, little attention has been paid to long-term effects of forest harvest on macroinvertebrate communities in headwater streams. This study investigated headwater stream macroinvertebrate communities in the H.J. Andrews Experimental Forest, Oregon,...

Spatial and vertical distribution of the invasive European green crab in a temperate estuarine system

Creator:: Lundeberg, Christopher A. and Weldon, Taylor
Abstract:: The European green crab, Carcinus maenas, is a generalist predator that has established invasive populations throughout the world, including the west coast of North America. In Oregon, strong cohorts of green crabs recruit only during major El Niño events. The goals of this study are to: 1) compare the abundance...

Status of the European Green Crab, Carcinus maenas, (aka 5-spine crab) in Oregon Estuaries. Report for 2023

Creator:: Yamada, Sylvia Behrens, Royer, Cameron, Schooler, Shon, Randall, Andrea, and Fisher, Jennifer
Abstract:: The European green crab (Carcinus maenas) has persisted in Oregon and Washington coastal estuaries since the late 1990s. A strong year class arrived during the 1998 El Niño, but numbers decreased and remained below 1 per trap per day until the arrival of the 2015-2016 El Niño. Since then, numbers...
