This study investigated the spatial distribution of juvenile North Pacific albacore (Thunnus alalunga) in relation to local environmental variability
[i.e. sea surface temperature (SST)], and two large-scale indices of climate variability, [the Pacific Decadal Oscillation (PDO) and theMultivariate
El Nino/Southern Oscillation Index (MEI)]. Changes in local and climate variables were...
Subhorizontal lake shorelines allow a geodynamic test of the size and extent of a hypothesized paleolake in central Tibet, the East Qiangtang Lake (EQL), during the last interglacial period (marine isotope stage (MIS) 5e). Reconstructions based on relict lake deposits suggest that the EQL would have been ~400 m deep...
The ¹⁴CO₂ composition of plant and soil respiration can be used to determine the residence time of photosynthetically fixed carbon before it is released back to the atmosphere. To estimate the residence time of actively cycled carbon in a temperate forest, we employed two approaches for estimating the Δ¹⁴CO₂ of...
Little research has been directed toward determining the status and ecological role of riparian areas in agricultural landscapes of the Willamette Valley, Oregon. A research project has been designed to contribute to the development and evaluation of alternative future scenarios and to improve the basic understanding of the role of...
The objective of the Alsea Watershed Study of Integrated Land-Water
Management is to learn how to obtain maximum productivity of a river
basin for the greatest public good. Specific objectives of the investigation
are:
* To determine effects of forestry, mining, industrial, agricultural,
municipal, fishery, game, recreational and other practices...
We quantified the relative influence of maternal fidelity to feeding grounds and natal
fidelity to breeding grounds on the population structure of humpback whales Megaptera novae-angliae based on an ocean-wide survey of mitochondrial (mt) DNA diversity in the North Pacific.
For 2193 biopsy samples collected from whales in 10 feeding...

Citizen-science projects engage volunteers to gather or process data to address scientific questions. But
citizen-science projects vary in their ability to contribute usefully for science, conservation, or public policy.
eBird has evolved from a basic citizen-science project into a collective enterprise, taking a novel
approach to citizen science by developing...
