31. [Article] Variation of Benthic Algal Assemblages Among Habitats in Subalpine Karstic Lakes and Implications for Bioassessment
Detecting early warning signs of ecosystem degradation in nature reserves requires ultrasensitive biological indicators. We assessed the potential of using multihabitat assessment of benthic algae (growing ...Citation -
In many parts of the world, the combined effects of wildfire, climate change, and population growth in the wildland-urban interface pose increasing risks to both people and biodiversity. These risks are ...

33. [Article] Spatio-Temporal Differentiation and Sociality in Spiders
Species that differ in their social system, and thus in traits such as group size and dispersal timing, may differ in their use of resources along spatial, temporal, or dietary dimensions. The role of ...Citation -
34. [Article] A biogeographical study of currently identified Oregon pseudoscorpions with an emphasis on western Oregon forms
The biogeography of the 50 currently identified Oregon species is reported from analyses of data from 2220 Berlese samples collected in a stratified, extensive sampling procedure, and from collection data ...Citation -
35. [Article] Alaska Aquatic Plant Survey Report 2005
Invasive, non-indigenous plants can degrade water quality and fish habitat when they invade lakes, ponds, and streams. Changes in plant community architecture in lakes due to invasion by canopy-forming ...Citation -
36. [Article] Final Coastal Lakes Aquatic Plant Survey Report
Invasive, non-indigenous plants can degrade water quality and fish habitat when they invade lakes, ponds, and streams. Changes in plant community architecture in lakes due to invasion by canopy-forming ...Citation -
37. [Article] Coastal Lakes Aquatic Plant Survey Report
Invasive, non-indigenous plants can degrade water quality and fish habitat when they invade lakes, ponds, and streams. Changes in plant community architecture in lakes due to invasion by canopy-forming ...Citation -
38. [Article] Stream Temperature Management in the Tualatin Watershed: Is it Improving Salmonid Habitat?
The purpose of this paper is to examine the literature from scientific and governmental entities that describes the problems with elevated stream temperatures in the Tualatin basin, the actions being taken ...Citation -
39. [Article] Forest Management Scenarios in a Changing Climate: Trade-Offs Between Carbon, Timber, and Old Forest
Balancing economic, ecological, and social values has long been a challenge in the forests of the Pacific Northwest, where conflict over timber harvest and old-growth habitat on public lands has been contentious ...Citation -
40. [Article] The Effectiveness of Vertebrate Passage and Prevention Structures: A Study of Boeckman Road in Wilsonville
One of the most obvious impacts roads have on the natural world is direct mortality to individual animals that attempt to cross roads. A less obvious but likely more important impact of roads on many species ...Citation
