Adolescent pregnancy is a serious problem which creates social and
emotional consequences for 1 in 10 teenaged girls and their families.
Although the severity of the problem has been well documented in the

information or to aid in the understanding of...
Since the early 1950's, the distribution of sediment at the
mouth of Redwood Creek has been altered by the effects of channel
aggradation and channelization along the lower reach. Severe flooding
in 1953, 1955, and 1964 caused bank erosion, landsliding, and
channel geometry changes along Redwood Creek. The increased sediment...
Data from nine stratocumulus clouds in the northeastern Pacific Ocean were analyzed
to determine the effect of aerosol particles on cloud microphysical and radiative properties.
Seven nighttime and two daytime cases were included. The number concentration of
below-cloud aerosol particles (> 0.10 μm diameter) was highly correlated with cloud
droplet...
Museum settings including aquariums, zoos and science centers rely heavily on their volunteer docent populations to interact with and communicate science and conservation concepts to the visiting public. The interactions docents have with museum visitors are important to meeting the educational expectations of museums and improving public science literacy as...
State-and-transition models (STMs) have been successfully used to
describe ecological dynamics in woodlands, shrublands, grasslands, and several other ecosystems. Changes in vegetation and soil are measured to gauge and predict plant community dynamics within ecological states and transitions between alternative ecological states. Ecological states and their boundaries are defined by...
Sustainable management of the world’s forests is a key component for conserving biodiversity, soil and water resources, mitigating climate change, strengthening economies, and promoting sustainable communities and human well-being, now and in the future. While international cooperation is important, the actual policies and management actions that affect forest conditions and...
The purpose of this study is to examine the relationship between land management practices of Indian communities prior to contact with Europeans and the nature or character of subsequent catastrophic forest fires in the Oregon Coast Range. The research focus is spatial and temporal patterns of Indian burning across the...
