We demonstrate a surface enhanced Raman scattering (SERS) substrate by integrating plasmonic-active SiO₂ nanotubes into Si₃N₄ gratings. First, the dielectric grating that is working under guided mode resonance (GMR) provides enhanced electric field for localized surface plasmon polaritons on the surface of metallic nanoparticles. Second, we use SiO₂ nanotubes with...
Estimating the abundance of long-lived, migratory animals is challenging but essential
for managing populations. We provide the first abundance estimates of endangered humpback
whales Megaptera novaeangliae from their breeding grounds in Oceania, South Pacific.
Using fluke photo-identification (1999−2004, n = 660 individuals) and microsatellite genotypes
(1999−2005, n = 840 individuals),...
Acculturation, defined as the process of adopting the behaviors and beliefs of the dominant host culture, is often associated with dietary change and negative health outcomes, such as increased risk for obesity and diet-related diseases. The large and rising immigrant population in the U.S. necessitates a better understanding of the...
Since the 1990s the U.S. and especially the Western U.S. have experienced more intense and costly fires. To help address this problem government agencies are increasingly looking at homeowners in fire-prone landscapes to mitigate fire risk. Part of this effort involves communicating risk and understanding how residents perceive risk. This...

Plagiobothrys hirtus is Oregon’s top priority for endangered plant species recovery, and the wetlands of Douglas County provide the only habitat for this plant in the world. The goal is to downlist this species from endangered to threatened, and in order to do that, existing populations must be protected, and...
