About this book
The author examines the relationship between organic size and variations in plant form, metabolism, reproduction, and evolution, and draws on the zoological literature to develop allometric techniques to address the problems of plant height, the relation between body mass and body length, and size-correlated variations in rates of growth. A valuable work for botanists interested in an original, quantitative approach to plant evolution and function, and for zoologists who want to learn more about the value of allometric techniques for studying evolution.
