| Research Abstract |
Since 1988, we have developed lattice version of Lotka-Volterra model as an individual-based model. Main results are as follows : 1. A simple population theory for mutualism : We derived simplest equations which contain essential features of mutualism. 2. In vivo study on the density effect of budding yeasts. We find two new events at inflection point of logistic growth : sudden stop of reproduction in daughter cells and mass explosion(apoptosis) of aged mother cells.
