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...
