Social discourse presents teenage childbearing as a “serious problem” that results in significant harm and expense to teenage mothers, their children, and society. Although the discourse of teenage childbearing has been multiple, overlapping, and contested, it has resulted in negative stereotyping and stigmatization of teenage mothers. Much of these stereotypes...
Managing wildlands to protect species and ecosystem services in response to climate change is challenging. To develop effective long-term strategies, natural resource managers need to account for the projected effects of climate change as well as the uncertainty inherent in those projections. Vegetation models are one important source of projected...
To meet growing energy demands and climate change goals, the use of renewable energy is increasingly becoming a policy priority globally, nationally, and at the state levels. In Oregon, the use of marine renewable energy and offshore wind remains part of this discussion but has yet to result in operational...
Obesity is achieved at the point where fat accumulation begins to exert deleterious effects on an organism. The human body accrues fat when there is an energy imbalance occurring, where caloric intake exceeds expenditure.Many anti-obesity drugs used in the past have had undesirable side effects, and currently there is a...

Existing research on the effectiveness of marine protected areas narrowly focuses on developing sets of management
indicators tied to outcomes described in management plans or on the achievement of a single objective such as an
increase in the size or number of older, more fecund female fish in a protected...
Rapid assessments are essential to establish baseline information of ecosystems that can
be used to design management plans such as marine protected areas. A rapid ecological
assessment was conducted to determine the conditions of coral reefs and reef fish around barrier islands that occur within the central Belize Barrier Reef...
We review how urbanization alters aquatic ecosystems, as well as actions that managers can take to remediate urban waters. Urbanization affects streams by fundamentally altering longitudinal and lateral processes that in turn alter hydrology, habitat, and water chemistry; these effects create physical and chemical stressors that in turn affect the...
The purpose of this study was to identify antimutagens in yogurt active against the
experimental colon carcinogen, N-methyl-N'-nitro-N-nitrosoguanidine (MNNG). Our
initial experiments showed that acetone extracts of yogurt, or milk fermented by various
lactic acid bacteria were antimutagenic against MNNG and 3,2'-dimethyl-4-aminobiphenyl
(DMAB) in the Ames test (Salmonella typhimurium TA...
The salt marshes of the Salmon River Estuary, Oregon have been of interest for decades due to their disturbance and restoration history, as well as the presence of long-term vegetation transects that were established as early as the 1970s. Vegetation abundance data have been gathered in the four sites of...
