Feeder dikes to the Columbia River Basalt Group (CRBG) large igneous province provide a rare opportunity to examine magma transport through the shallow crust during flood basalt eruptions. Over 70% of the CRBG erupted from the Chief Joseph dike swarm, which is exposed across southeastern Washington, eastern Oregon, and western...
Climate change is expected to change the distribution of species. For long-lived, sessile
species such as trees, tracking the warming climate depends on seedling colonization of
newly favorable areas. We compare the distribution of seedlings and mature trees for all but
the rarest tree species in California, Oregon and Washington,...

To understand mechanisms linking ecosystem processes and microbial diversity in freshwater ecosystems, bacterial productivity and the metacommunity dynamics of species sorting and mass effects were investigated in an 18 ha headwater lake in northern Alaska. On most sampling dates, the phylogenetic composition of bacterial communities in inflowing streams (inlets) was...

OBJECTIVE: The associations of some risk factors with cardiovascular disease (CVD) are attenuated in
older age; whereas others appear robust. The present study aimed to compare CVD risk factors across
older age. METHODS: Participants (n = 4883) in the Cardiovascular Health Study free of prevalent CVD,
were stratified into three...

Data from large-scale biological inventories are essential for understanding and managing Earth's ecosystems.
The Forest Inventory and Analysis Program (FIA) of the U.S. Forest Service is the largest biological inventory in
North America; however, the FIA inventory recently changed from an amalgam of different approaches to a
nationally-standardized approach in...

Because of their unique physiology, lichen communities are highly sensitive to climatic conditions, making them ideal bioindicators for climate change. Southeast and south-central Alaska host diverse and abundant lichen communities and are faced with a more rapidly changing climate than many more southerly latitudes. We develop sensitive lichen-based indicators for...
