Modeling the LH surge in the human menstrual cycle.
Viewed simply, the menstrual cycle is an attracting cycle of the feedback dynamics between hormones produced by the hypothalamus/pituitary and hormones produced by maturing follicles in the ovaries

Lotka-Volterra Systems

Geometric analysis of Lotka-Volterra models of species competition in n-dimensions.
