Much of our understanding of the mapping of the environment to population dynamics through demography has arisen from the study of empirical model systems of which there is a continuum ranging from laboratory systems, like drosophila, callosobruchus, sancassania1 to systems studied in depth in the field, like soay sheep or.

The model handles disintegrative process in a highly parsimonious manner.
Consequently, potentially useful characteristics of pest ecology that can be utilized in the development of pest. Population dynamics models remain largely deterministic, although the presence of random fluctuations in nature is well recognized. This deterministic approach is based on the implicit assumption that systems can be separated into a deterministic part that captures the essential features of the system and a random part that can be neglected.

Much of our understanding of the mapping of the environment to population dynamics through demography has arisen from the study of empirical model systems of which there is a continuum ranging from laboratory systems, like drosophila, callosobruchus, sancassania1 to systems studied in depth in the field, like soay sheep or red deer. However, examples of such patterns in ecological systems are scarce. Peters approach to answering these questions blends theory building with the analysis of data. Here we consider the interaction of three or more species, focusing on examples of plankton dynamics and lynxhare cycles to illustrate the range of complex behaviour. In contrast with other analyses, we consider the effect on the third trophic level by the firstlevel parameters.
