Descripción: Animal population ecology has become a rapidly expanding natural science over the past decade. This trend is the result of many interacting factors, not least among them being; the maturation of ecology from a more or less descriptive and a priori science to the beginnings of a quantitative, deductive-inductive approach; and, the need for a better understanding of the effect of pesticides and biological agents on the trend of pest populations. Such knowledge is almost completely lacking, although the work in Canada of R.F. Morris, E.J. LeRoux and their associates forms the basis of such a need. Obviously any quantitative study aimed at understanding the dynamics of any animal population, and hence the causes that account for changes in the rise and fall of such a population, must be a valuable addition to knowledge on this subject.
