    Adams, Vincent T.
    Abstract:
    Barley yellow dwarf virus (BYDV) is a globally distributed pathogen of grasses that is transmitted by aphids.

  • Resource uptake and host tissue chemistry: Implications for competition and disease

    Creator:
    Schumann, Canan B.
    Abstract:
    Maintenance of optimal nutrient supplies is fundamental to the functioning of vertebrate, invertebrate, bacterial and plant physiology. Organisms on this planet compete with each other primarily to fulfill nutritional needs in order to maximize their health, wellbeing, and reproductive success. Here we examine nutrient concentrations in several different grass species...
