This publication is a reference guide for forest soils productivity and management. Main topics include (1) understanding and managing risk, (2) soil characteristics that affect productivity, (3) soil survey information for forestland managers/management of soil erosion, (4) managing mass wasting risk, (5) managing soil disturbance, and (6) maintaining adequate nutrient...

Variable ocean conditions can greatly impact
prey assemblages and predator foraging in marine ecosystems.
Our goal was to better understand how a change in
ocean conditions influenced dietary niche overlap among
a suite of midtrophic-level predators. We examined the
diets of three fishes and one seabird off central Oregon
during...

Phylogenetic analyses of assemblage membership provide insight into how
ecological communities are structured. However, despite the scale-dependency of many
ecological processes, little is known about how assemblage and source pool size definitions can
be altered, either alone or together, to provide insight into how ecological diversity is
maintained. Moreover, although...

Predicting the net effects on the carbon and water
balance of semi-arid forests under future conditions depends
on ecosystem processes responding to changes in
soil and atmospheric drought. Here we apply a combination
of field observations and soil–plant–atmosphere modeling
(SPA) to study carbon and water dynamics in a regenerating
ponderosa...
BACKGROUND: Many commentators on ‘‘direct-to-consumer’’ genetic risk information have raised concerns that giving results
to individuals with insufficient knowledge and training in genomics may harm consumers, the health care system, and
society. In response, several commercial laboratories offering genomic risk profiling have shifted to more traditional ‘‘direct-to-provider’’ (DTP) marketing strategies,...

AIM: Species that breed sympatrically often occupy different foraging niches to
mitigate competition for prey. When resource availability declines at the end of
the breeding season, some animals migrate to regions with more favourable
environmental conditions. When these life-history traits combine, foraging
habitat preferences may continue to influence migration patterns...

The Corvallis fault is a 50 km long northeast-trending structure, part of which defines the boundary between the central Willamette Valley and the east-central Coast Range of Oregon. Previously the fault had been mapped as either a high-angle reverse or normal fault, with the east block down. New gravity data...

This report reviews the state of the California Current System (CCS) between winter 2012 and spring 2013, and includes observations from Washington State to Baja California. During 2012, large-scale climate modes indicated the CCS remained in a cool, productive phase present since 2007. The upwelling season was delayed north of...
