The hazards-of-place model of vulnerability to environmental hazards posits that vulnerability has biophysical and social components. While biophysical characteristics are important in predicting locations of elevated wildfire risk, the social characteristics of human communities may help us predict locations of elevated wildfire impacts. We examine the relationship between biophysical and...
The recovery of a 1.5 million yr long ice core from Antarctica represents a keystone of our understanding of Quaternary climate, the progression of glaciation over this time period and the role of greenhouse gas cycles in this progression. Here we tackle the question of where such ice may still...
Streams across the world are highly fragmented due to the presence of in-stream barriers (e.g., dams and stream-road crossings), many of which restrict or block fish passage. Retrofitting or replacing these structures is a high priority for restoring habitat connectivity for native fishes and other aquatic organisms in the Pacific...
The Newell Farmstead (35MA41) archaeological site lies in the heart of the French Prairie in the Willamette Valley in the Champoeg State Heritage Area, Oregon.

It is not unusual to see stranded or washed-up marine animals and birds along any
coastline. Various networks nationwide exist to report marine mammals and sea birds,
yet, we have been unable to find a network in Oregon or nationally to report other
stranded marine animals, namely fish, cephalopods, and...
Extreme water levels generating flooding in estuarine and coastal environments are often driven by compound events, where many individual processes such as waves, storm surge, streamflow, and tides coincide. Despite this, extreme water levels are typically modeled in isolated open-coast or estuarine environments, potentially mischaracterizing the true risk of flooding...
Urban African American adolescents exhibit high levels of risk behavior, disproportionately high rates of sexually transmitted infections (STIs), and are at risk for acquiring Human Immunodefiency Virus (HIV). To date, interventions that address the high rates of STIs in this population demonstrate only moderate efficacy. As researchers strive to develop...

Environmental stressors and disease agents can perturb the delicate balance of the coral host...
If the study of the fisheries dynamics increasingly seeks to take into
account the evolution of fishing fleets, the main mechanisms which govern
their evolution at the local, national or international levels, are often not
studied at all, or only partially studied. This applies in particular to vessel
entry and...
The interplay of natural selection and genetic drift, influenced by geographic isolation, mating systems and population size, determines patterns of genetic diversity within species.

Establishing marine protected areas (MPAs) often results in fishers being
displaced from at least some of their existing grounds. A direct
consequence of this is that governments may be required to make
compensatory payments to the firms that are affected. Experience has
demonstrated that these payments can be significant, as...
Although a significant amount of research has investigated the effect of sexualization on women's body esteem and cognitive performance, few researchers have examined the effect of sexualization on girls.
