The ascomycete Geosmithia morbida and the walnut twig beetle Pityophthorus juglandis are associated with thousand
cankers disease of Juglans (walnut) and Pterocarya (wingnut). The disease was first reported in the western United States
(USA) on several Juglans species, but has been found more recently in the eastern USA in the...
INTRODUCTION: Many species of ambystomatid salamanders are dependent upon highly variable temporary wetlands
for larval development. High larval densities may prompt the expression of a distinct head morphology that may
facilitate cannibalism. However, few studies have characterized structural cannibalism within natural populations of
larval salamanders. In this study we used...
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,...
In 2014, the California Current (~28˚–48˚N) saw average, or below average, coastal upwelling and relatively low productivity in most locations, except from 38˚–43˚N during June and July. Chlorophyll-a levels were low throughout spring and summer at most locations, except in a small region around 39˚N. Catches of juvenile rockfish (an...
These datasets were used in the prospective meta-analysis of northern spotted owl reproductive rates over 25 years across 11 study areas located throughout the range of the owl. A multi-state occupancy file was created by collapsing site-specific information on owl reproductive status into bimonthly (2 per month) survey occasions. These...
