Euphausia pacifica occupy a remarkably wide range of ecosystems. We examined the
differences in brood sizes from eight regions of the North Pacific to explore how variation
in the brood size might contribute to their success over such a range. We...

This study addresses the occurrence, severity, and extent of hypoxia over the continental shelf of the northern
California Current (40–48.5°N latitude) from 1998 to 2012. Clear seasonal trends exist in the timing and duration
of hypoxia. The...

Larval supply determines year-class strength of fisheries and complex ecological
interactions among adults of benthic marine species. In upwelling regions, a latitudinal cline in
the intensity and persistence of upwelling is thought to affect...

Many endemic species, particularly those on
remote islands, have been driven to extinction or near extinction
by anthropogenic influences. The short-tailed albatross
Phoebastria albatrus once numbered in the millions
but was thought to be extinct...

The etiology of canine gallbladder mucocele (GBM) has not yet been identified. However, several studies
have linked GBM in dogs to particular breeds (Shetland Sheepdogs are commonly implicated), concurrent endocrine disease
(hyperadrenocorticism...

Research on regulatory mechanisms in biological populations often focuses on environmental covariates. An integrated
approach that combines environmental indices with organismal-level information can provide additional insight on
regulatory...

The eruption of South Sarigan Seamount in the southern Mariana arc
in May 2010 is a reminder of how little we know about the hazards associated with
submarine explosive eruptions or how to predict these types of eruptions. Monitored
by local...

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...

With 97% of the world’s freshwater resources stored underground, the connection
between groundwater resources to the metrics of space, scale and time common to the
geographic study of natural resources has not been extensively investigated by...

In 2001, an extreme drought tightened water supply in the Upper Klamath
Basin (basin) while earlier increases in Endangered Species Act (ESA) water
requirements for basin fish species that same year elevated demands. The Bureau of

This research provides details of water resource conflict and cooperation in
Oregon between 1990 and 2004 by using an event database methodology. Events were
concentrated in four of 18 basins. No basin accounted for more that 25% of the total...
