Employing dynamic model to study food web stability and possible regime shifts in Somme Bay

The stability of food web is a hot issue and a research frontier in ecology which has attracted widespread interests. In this research, a new investigation is conducted on the stability of food web. We take Somme Bay as a study case and employ a dynamic model to analyze food web characteristics, wit...
