We develop the idea of risk transmission from large wildfires and apply network analyses to understand its importance on a 0.75 million ha US national forest. Wildfires in the western US frequently burn over long distances (e.g., 20-50 km) through highly fragmented landscapes with respect to ownership, fuels,
management intensity,...
Patterns of social interaction influence how knowledge is generated, communicated,
and applied. Theories of social capital and organizational learning suggest that
interactions within disciplinary or functional groups foster communication of
knowledge, whereas interactions across groups foster generation of new knowledge.
We used social network analysis to examine patterns of social...
The influence of overstory openness on the reproductive
ecology of Pacific yew (Taxus brevifolia Nutt.) was
investigated on 4 sites in western Oregon over 2 years. The
breeding system of T. brevifolia was found to deviate from
pure dioecy under a broad range of canopy and site
conditions. Production of...
The development of new technologies in science is a balance between existence and use. There are three versions of this duality – something is built and users come, something is built and users don’t come, and, finally, potential users show up but the ballpark has not yet been built. In...
The effects of forest cutting on forested systems and the biotic components of those systems has been at the forefront of scientific research. The inventory and monitoring of biodiversity is one technique used for measuring the effects of forest management. Because bioinventory studies are expensive, indicator species are often sought...
The purpose of this study was to describe the life cycles,
feeding ecology, and habitat use of western species in the mayfly
family Ephemerellidae. Data were used to compare the ecological
relationships and strategies among species and to examine patterns
of adaptive radiation within the family. Data were further used...
This is an integrated assessment across terrestrial, freshwater, and coastal marine realms. It includes the coast range of Oregon and Washington as well as Vancouver Island in British Columbia. The marine portion only includes the coastline and shallow subtidal; the next iteration will include the offshore component.
A method based on fatty acid (FA) analysis is used to profile microbial community structure (MCS). Various extraction protocols are available, which alter the types of FAs extracted from soils. The more time consuming but widely used protocol extracts only FAs from phospholipids (PLFA). This technique is desirable because PLFAs...
