  • Effects of atrazine on olfactory-mediated behaviors in Pacific lamprey (Entosphenus tridentatus)

    Creator:
    Smith, April G.
    Abstract:
    Pacific lamprey (Entosphenus tridentatus) are experiencing population declines throughout their range. Xenobiotics could be an important risk factor for lamprey populations. Our goal was to establish if common herbicides, as used in forest management, could affect reproductive fitness. We determined that atrazine was a likely compound of greatest concern to...

  • Long-term fertilizer input influences total and bioavailable metal in agricultural soils and crops

    Creator:
    Pérez, Angela L.
    Abstract:
    Protection of the quality and integrity of food supplies is of global concern. Crops can accumulate non-nutritive and sometimes toxic metals and metalloids. Accumulated metals/metalloids can come in part, from fertilizers, which may contain variable levels of non-nutritive metals or metalloids such as arsenic (As), cadmium (Cd), lead (Pb), nickel...

  • Adapting computer science technologies to bridge critical gaps in proposed Tox21 risk assessment programs

    Creator:
    Larkin, Andrew
    Abstract:
    In 2004 the National Toxicology Program published an article describing their intent to pursue toxicology testing and risk assessment practices solely reliant on high throughput in vitro datasets and in silico modeling for dose-response assessments. Support and contributions form regulatory agencies and a significant portion of the life sciences community...

  • Agricultural impacts on amphibian survival, growth, and distributions

    Creator:
    Baker, Nick J.
    Abstract:
    The potential impact of chemical contaminants and conservation practices on amphibians in agricultural landscapes is a key research topic globally. Amphibians represent a common group in many freshwater systems and are currently experiencing worldwide population declines. Global amphibian declines may be attributed to a number of causes, including habitat loss,...
