Discrete Population Models for a Single Species,hatsoever between successive generations and so population growth is in discrete steps. For primitive organisms these can be quite short in which case a continuous (in time) model may be a reasonable approximation. However, depending on the species the step lengths can vary widely. A year is common.

Continuous Models for Interacting Populations,akes for structurally complex communities. We consider here systems involving two or more species, concentrating particularly on 2-species systems. There are three main types of interaction, (i) If the growth rate of one population is decreased and the other increased the populations are in a . situ

Discrete Growth Models for Interacting Populations,owth models, there are the same main types of interaction namely predator-prey, competition and mutualism. In a predator-prey situation the growth rate of one is enhanced at the expense of the other whereas in competition the growth rates of both are decreased while in mutualism they are both increa

Reaction Diffusion, Chemotaxis and Non-local Mechanisms,icles spread out as a result of this irregular individual motion of each particle. When this microscopic irregular movement results in some macroscopic or gross regular motion of the group we think of it as a . process. Of course there may be interaction between particles for example, or the environ
