Descriptif
The best way to distinguish between various ecological influences and phylogeny is the simultaneous study of a set of syntopic/paratopic species differing basically in one or two ecological aspects and in the degree of their phylogenetic relatedness (Henle 1987). I used such an approach to compare the life histories of a community of arid zone lizards in Eastern Australia. Due to time constraints and limitations imposed by the composition of the community, the attempted Greek-square-design had to remain incomplete, and a complete statistical seperation of all ecological and phylogenetic effects was not possible. However, the study reported in this thesis is one of the few which tried to rigorously separate these effects. It also contributes to a broader understanding of the evolution of life histories in lizards by including species from families, or with life-styles so far almost completely neglected in empirical studies. It is hoped that this thesis contributes to a further understanding of evolutionary ecology by stimulating research on the many questions which emerge from the synthesis of the results of this and other studies.
