  • Light and the behavior of pelagic animals during night and crepuscular periods

    Creator:
    Wisdom, Daniel W.
    Abstract:
    Light plays an important role in ecological processes in the ocean both day and night. While relatively inexpensive, off the shelf instruments are available to measure Photosynthetically Active Radiation or PAR during the day, efforts to quantify light levels at night have proven more difficult. The goal of this work...

    Abstract:
    Cadmium is a common impurity in phosphatic fertilizers and may contribute to soil Cd accumulation. Changes in total and bioavailable Cd burdens to agricultural soils and the potential for plant Cd accumulation resulting from fertilizer input was investigated. Three year field studies were conducted using three dose levels of cadmium-rich,...

    Abstract:
    A variety of approaches are used in sagebrush conservation. The Sagebrush/Sage Grouse Habitat Metric is one of several ecological measures that have been developed to help managers determine where to invest limited resources and how to calculate the ecological impact and improvement associated with the implementation of conservation actions.

    Dail, David (David Andrew)
    Abstract:
    Obtaining accurate estimates of animal abundance is made difficult by the fact that most animal species are detected imperfectly. Early attempts at building likelihood models that account for unknown detection probability impose a simplifying assumption unrealistic for many populations, however: no births, deaths, migration or emigration can occur in the...

    Abstract:
    Quaking aspen (Populus tremuloides) is one of a few iconic trees that symbolize the spirit of the West. Though sparsely distributed throughout Oregon, aspen is an important species, providing a long history of benefits to both people and wildlife. “Quakies,” as many call aspen, are well liked by ranchers, hunters,...

    Creator:
    Akegbejo-Samsons, Yemi and Adeoye, Deji
    Abstract:
    Aquaculture, the farming of aquatic organisms especially fish, in Nigeria is dated back to the 1940s at Onikan Experimental farm, South West Lagos and the 160ha industrial scale fish farm, Middle Belt, Panyam, Jos in 1951. Since then, great expansion has been witnessed in Nigeria’s aquaculture industry; graduating from extensive...
