Relationships between Swiss needle cast and ectomycorrhizal fungus diversity

Creator:: Luoma, Daniel L. and Eberhart, Joyce L.
Abstract:: Swiss needle cast (SNC) is a disease specific to Douglas-fir (Pseudotsuga menziesii) caused by the ascomycete Phaeocryptopus gaeumannii. Here we examine characteristics of the EM fungus community that are potentially useful in predictive models that would monitor forest health. We found that mean EM density (number of colonized root tips/soil...

Recovery of ectomycorrhizal fungus communities fifteen years after fuels reduction treatments in ponderosa pine forests of the Blue Mountains, Oregon

Creator:: Hart, Benjamin T. N., Smith, Jane E., Luoma, Daniel L., and Hatten, Jeff A.
Abstract:: Managers use restorative fire and thinning for ecological benefits and to convert fuel-heavy forests to fuel-lean landscapes that lessen the threat of stand-replacing wildfire. In this study, we evaluated the long-term impact of thinning and prescribed fire on soil biochemistry and the mycorrhizal fungi associated with ponderosa pine (Pinus ponderosa)....

Ectomycorrhizal communities of ponderosa pine and lodgepole pine in the south-central Oregon pumice zone

Creator:: Garcia, Maria O., Smith, Jane E., Luoma, Daniel L., and Jones, Melanie D.
Abstract:: Forest ecosystems of the Pacific Northwest of the USA are changing as a result of climate change. Specifically, rise of global temperatures, decline of winter precipitation, earlier loss of snowpack, and increased summer drought are altering the range of Pinus contorta. Simultaneously, flux in environmental conditions within the historic P....

A Bioecological Model of Grief Recovery : Theory and Test of the Model

Creator:: Romo, Daniel L.
Abstract:: A primary aim of bereavement research is to alleviate suffering and promote well-being at the junction of life and death for the survivor in an attachment relationship. Bereavement research in the last decade has focused primarily on examining grief recovery within the context of intrapersonal processes. This emphasis has often...

The Influence of Environmental Value Orientation and Climate Change Beliefs on the Firewise Behaviors of Central Oregon Residents

Creator:: Weston, Daniel L.
Abstract:: Over the past two decades, the western United States has experienced many of the costliest and most severe wildfires in history. To mitigate the effects of the growing threats posed by wildfires, residents in at-risk communities are encouraged to protect their homes and property by adopting Firewise recommendations. This article...

Influence of Food Limitation on Reproductive Performance of Burrowing Owls

Creator:: Haley, Katherin L. and Rosenberg, Daniel K.
Abstract:: Reproductive strategies of birds are shaped by patterns of food supply, yet empirical evidence of the consequences and mechanisms of food limitation on reproductive performance is inconsistent, probably due to variable responses from species of differing life-history strategies. We tested the hypothesis that food supplementation would increase reproductive rates of...

Trait-based approaches to linking vegetation and food webs in early-seral forests of the Pacific Northwest

Creator:: Campbell, John L. and Donato, Daniel C.
Abstract:: Both the structure and composition of naturally generated early-seral forests in the Pacific Northwest (PNW) can be profoundly different than that of more developed forest seres, especially in the period after a major disturbance but before conifers re-develop a closed canopy. While it is reasonable to suggest that the unique...

Community ecology of invasions: direct and indirect effects of multiple invasive species on aquatic communities

Creator:: Preston, Daniel L. and Henderson, Jeremy S.
Abstract:: With many ecosystems now supporting multiple nonnative species from different trophic levels, it can be challenging to disentangle the net effects of invaders within a community context. Here, we combined wetland surveys with a mesocosm experiment to examine the individual and combined effects of nonnative fish predators and nonnative bullfrogs...

Burning the legacy? Influence of wildfire reburn on dead wood dynamics in a temperate conifer forest

Creator:: Donato, Daniel C., Fontaine, Joseph B., and Campbell, John L.
Abstract:: Dynamics of dead wood, a key component of forest structure, are not well described for mixed-severity fire regimes with widely varying fire intervals. A prominent form of such variation is when two stand-replacing fires occur in rapid succession, commonly termed an early-seral “reburn.” These events are thought to strongly influence...
