Riley Fehr Bernard, Jonah Evans, Nathan W. Fuller, Jonathan D. Reichard, Jeremy T. H. Coleman, Christina J. Kocer, Evan H. Campbell Grant
2020, Conservation Science and Practice (1)
Management decisions for species impacted by emerging infectious diseases are challenging when there are uncertainties in the effectiveness of management actions. Wildlife managers must balance trade‐offs between mitigating the effects of the disease and the associated consequences on other aspects of the managed system. An example of this challenge is...

Kayla Crosbie, Geoff A. Abers, Michael Everett Mann, Helen A. Janiszewski, Kenneth C Creager, Carl W Ulberg, Seth C. Moran
2020, Journal of Geophysical Research (124) 8358-8375
Mount St. Helens (MSH) lies in the forearc of the Cascades where conditions should be too cold for volcanism. To better understand thermal conditions and magma pathways beneath MSH, data from a dense broadband array are used to produce high‐resolution tomographic images of the crust and upper mantle. Rayleigh‐wave phase‐velocity...
