For the past several decades, amphibian populations have been decreasing
around the globe at an unprecedented rate. Batrachochytrium dendrobatidis (Bd), the fungal
pathogen that causes chytridiomycosis in amphibians, is contributing to amphibian declines.
Natural and anthropogenic environmental factors are hypothesized to contribute to these
declines by reducing the immunocompetence of...
Increasing public awareness that the Cascadia subduction zone in the Pacific Northwest is capable of great earthquakes (magnitude 9 and greater) motivates the Cascadia Initiative, an ambitious onshore/offshore seismic and geodetic experiment that takes advantage of an amphibious array to study questions ranging from megathrust earthquakes, to volcanic arc structure,...
Marine sediments around volcanic islands contain an archive of volcaniclastic deposits, which can be used to reconstruct the volcanic history of an area. Such records hold many advantages over often incomplete terrestrial data sets. This includes the potential for precise and continuous dating of intervening sediment packages, which allow a...
