The introduction of fish has decimated many amphibian populations through increased predation, primarily on their larvae. Some amphibian species now occupy marginal habitats as a response to the presence of introduced fish predators. Such habitats may include ephemeral water bodies where fish do not usually occur, although breeding in these suboptimal(More)
In 1979 and 1981, a genetic marker was bred into one of the five identifiable subpopulations of pink salmon [Oncorhynchus gorbuscha (Walbaum)] in the Auke Lake drainage in Southeast Alaska. As a result of the marking effort, the frequencies of two malate dehydrogenase (MDH-B1, 2*) alleles were changed in the marked subpopulation, but not in other(More)
Liquid crystal-based Optical Phased Arrays (OPAs) are a disruptive technology for a variety of electronic beam manipulation functions, including steering and control of polarization, amplitude, and phase. For applications in the emerging field of space-based laser communications, such devices must be operable in an extreme environment for an extended period(More)
Nondestructive firmness measurement is critical to assuring postharvest quality and marketability of apples. In this research, two in-house developed sensors (bioyield and spectral scattering) and two commercial sensors (acoustic and visible and shortwave nearinfrared (Vis-SWNIR) spectroscopy), were evaluated for assessing the firmness of apples. Spectral(More)
