Abstract

A model is formulated aiming to describe census data for populations changing non-symmetrically with time. The model is based on the concept of ecological time, conceived as an environmental gradient. A method of changing time scales. by using a periodic equation relating ecological to standard clock time unit, is presented. The model has been applied to simulate phenological curves of population abundance for oribatid mites and Collembola from a Mediterranean ecosystem
