Comparative Demography And Life History Evolution Of Plants, Cyril Mbeau Ache Jan 2014

Comparative Demography And Life History Evolution Of Plants, Cyril Mbeau Ache

School of Biological and Marine Sciences Theses

Explaining the origin and maintenance of biodiversity is a central goal in ecology and evolutionary biology. Some of the most important, theoretical explanations for this diversity centre on the evolution of life histories. Comparative studies on life history evolution, have received significant attention in the zoological literature, but have lagged in plants. Recent developments, however, have emphasised the value of comparative analysis of data for many species to test existing theories of life history evolution, as well as to provide the basis for developing additional or alternative theories. The primary goal of this study was to explore existing theories of …
