Considerations for the use of ecological indicators in restoration effectiveness evaluation

Creator:: Independent Multidisciplinary Science Team (Or.)
Abstract:: This report focuses on the use of ecological indicators to evaluate ecological restoration effectiveness, particularly restoration aimed at salmonid recovery and watershed restoration efforts under the Oregon Plan for Salmon and Watersheds. Part 1 addresses conceptual issues including how indicators can be linked to monitoring, how conceptual models can be...

Soil biochemical measures as ecological indicators across agricultural and forest ecosystems of Oregon

Creator:: Knight, Timothy R.
Abstract:: A variety of soil properties have been proposed and tested as potential indicators of soil quality. This study was conducted in an effort to produce a standardized soil quality index for systems in Oregon. Soils in both forested and agricultural systems were sampled in a wide variety of locations, climates,...

Texture analysis riparian coniferous forest ADAR imagery to identify potential ecological indicators for monitoring

Creator:: Barker, Jerry R., Bollman, Mike, Fiorella, M., Bradshaw, Gay, and Ringold, P. L.
Abstract:: The Airborne Data Acquisition and Registration (ADAR) remote sensing system captured one-meter resolution imagery of 25 different riparian sites in drift Creek Basin of coastal northwestern Oregon, USA. The multispectral, digital data characterized riparian areas with the intent to develop ecological indicators for long-term monitoring.

Evaluation of bacterial community indicators of stream sanitary and ecological condition

Creator:: Bracken, Caragwen L.
Abstract:: The focus of this research was to develop bacterial community indicators of stream sanitary and ecological condition. The first study compared substrate utilization patterns between centrifuged and uncentrifuged split samples. We found a shift in the relative proportion of each group of bacteria following centrifugation, with a marked increased in...

Lidar remote sensing variables predict breeding habitat of a Neotropical migrant bird

Creator:: Goetz, Scott J., Steinberg, Daniel, Betts, Matthew G., Holmes, Richard T., Doran, Patrick J., Dubayah, Ralph, and Hofton, Michelle
Abstract:: A topic of recurring interest in ecological research is the degree to which vegetation structure influences the distribution and abundance of species. Here we test the applicability of remote sensing, particularly novel use of waveform lidar measurements, for quantifying the habitat heterogeneity of a contiguous northern hardwoods forest in the...

Determinants of moth diversity and community in a temperate mountain landscape: vegetation, topography, and seasonality

Creator:: Highland, Steven A., Miller, Jeffrey C., and Jones, Julia A.
Abstract:: Macromoth diversity, abundance, and community structure in the topographically complex HJ Andrews Experimental Forest and LTER site was studied on the west slope of the Cascade Range, Oregon. Data on 493 macromoth species (62,221 individuals) was sampled eight times/year at 20 locations from 2004 to 2008 and examined using multivariate...

Are large macroalgal blooms necessarily bad? nutrient impacts on seagrass in upwelling-influenced estuaries

Creator:: Hessing-Lewis, Margot L., Hacker, Sally D., Menge, Bruce A., McConville, Sea-oh, and Henderson, Jeremy
Abstract:: Knowledge of nutrient pathways and their resulting ecological interactions can alleviate numerous environmental problems associated with nutrient increases in both natural and managed systems. Although not unique, coastal systems are particularly prone to complex ecological interactions resulting from nutrient inputs from both the land and sea. Nutrient inputs to coastal...

Density dependence and population regulation in marine fish: a large-scale, long-term field manipulation

Creator:: Hixon, Mark A., Anderson, Todd W., Buch, Kevin L., Johnson, Darren W., McLeod, J. Brock, and Stallings, Christopher D.
Abstract:: dependence and regulation of relatively large local populations? If so, what are the causative mechanisms and their implications? We conducted an eight-year multigeneration study of population dynamics of bicolor damselfish (Stegastes partitus) inhabiting four large coral reefs in the Bahamas. After a four-year baseline period, it was clear that two...

The plant phenology monitoring design for The National Ecological Observatory Network

Creator:: Elmendorf, Sarah C., Jones, Katherine D., Cook, Benjamin I., Diez, Jeffrey M., Enquist, Carolyn A. F., Hufft, Rebecca A., Jones, Matthew O., Mazer, Susan J., Miller-Rushing, Abraham J., Moore, David J. P., Schwartz, Mark D., and Weltzin, Jake F.
Abstract:: Phenology is an integrative science that comprises the study of recurring biological activities or events. In an era of rapidly changing climate, the relationship between the timing of those events and environmental cues such as temperature, snowmelt, water availability, or day length are of particular interest. This article provides an...
