Biome function is largely governed by how efficiently available resources can be used and yet for water, the ratio of direct biological resource use (transpiration, E_T) to total supply (annual precipitation, P) at ecosystem scales remains poorly characterized. Here, we synthesize field, remote sensing and ecohydrological modelling estimates to show...
Steepland valleys subject to debris flows incise bedrock even as episodic deposition typically covers valley bottoms. This paper’s hypothesis is that, while continual fluvial processes evacuate deposits, storage of episodic deposition drives valley widening and, thereby, creation of accommodation space for sediment storage on the valley floor. Data from three...
Fire suppression has increased fuel loads and fuel continuity in mixed-conifer ecosystems, resulting in forest structures
that are vulnerable to catastrophic fire. This paper models fire behaviour in a mixed-conifer forest and investigates how
silvicultural and fuels treatments affect potential fire behaviour. The computer program FARSITE was used to spatially...

PREMISE OF THE STUDY: We report the de novo assembly and characterization of the transcriptomes of Brachypodium sylvaticum
(slender false-brome) accessions from native populations of Spain and Greece, and an invasive population west of Corvallis,
Oregon, USA.
METHODS AND RESULTS: More than 350 million sequence reads from the mRNA libraries...
We measured surface soil (0–15 cm) C and N pools and processes inside and outside an area that had been trenched 13 years earlier in an old-growth conifer forest (>450 years) to assess the long-term impacts of reduced root inputs on C and N turnover. Trenching, combined with frequent clipping...
Since nucleic acids were first extracted directly from the environment and sequenced, metagenomics has grown to one of the most data-rich and pervasive techniques for understanding the taxonomic and functional diversity of microbial communities. In the last decade, cheaper sequencing has democratized the application of metagenomics and generated billions of...
The provision of many ecosystem services depends on the spatial pattern of land use across multiple landowners. Even holding land use constant, ecosystem service provision may change through time due to climate change. This paper develops an auction mechanism that implements an optimal solution for providing ecosystem services through time...
Plantago ovata Forssk. (Plantaginaceae) is a species that, in North America, inhabits desert and Mediterranean habitats of the southwest United States, northwest Mexico, and the Channel Islands of California and Mexico. In the Eastern Hemisphere, P. ovata inhabits desert regions ranging from the Canary Islands, across northern Africa to India....
A statistical description of the deep ocean internal wave field is presented using measurements from the Midocean Acoustic Transmission Experiment, conducted near Cobb Seamount in the NE Pacific (46°46'N, 30°47'W) during June–July 1977. The unique feature of this experiment is the variety of data obtained simultaneously from the same location:...
