The Evolutionary Biology of Colonizing Species

by Peter Angas Parsons

Overview

Professor Parsons uses the colonizing species as a case study in the dynamics of microevolution at work in living systems. The colonizing species, a lie, and potentially disruptive force in a 'naïve' habitat, is studied primarily as an ecological phenotype and more generally as an ecological behavioural phenotype. Conventional life-history traits and components of fitness, can be incorporated into these phenotypes. Integrating genetic change, natural selection, and the interaction of the species with its environment and other living systems therein, the colonizing species is transformed into a sophisticated and complex source of data for understanding evolutionary biology. Throughout the book it is emphasized that using the organism as the unit of selection is the most direct way of understanding the nature of successful colonizing phenotypes, and, by using specific phenotypic criteria, the prediction of likely successful colonists can be made. Such criteria include tolerance of extreme environments, resource utilization, reproductive capacity, and relative abundance.
