  • Dynamical systems theory in mathematical biology and environmental science has attracted much attention from many scientific fields as well as mathematics. For example, “chaos” is one of its typical topics. Recently the preservation of endangered species has become one of the most important issues in biology and environmental science, because of the recent rapid loss of biodiversity in the world. In this respect, permanence or persistence, new concepts in dynamical systems theory, seem important.

  • Organic milk production systems rely on ecologically based practices that virtually prohibit the use of antibiotics and hormones in the cow herd and the use of synthetic chemicals in the production of cattle feed. Organic milk production systems also attempt to accommodate the animals’ natural nutritional and behavioral requirements, for example ensuring that dairy cows have access to pasture (Greene and Kremen).
