This paper typifies the advanced computational analyses and simulations being applied in particular to growth and spatial distribution of clonal, modular organisms.
2. de Kroon, H., and J. van Groenendael. 1997. The Ecology and Evolution of Clonal Plants. Backhuys Publishers, Leiden, The Netherlands. The perspectives of multiple authors on the ecology and evolutionary biology of clonal plants. In many ways, this is the counterpart of the book on clonal animals by Hughes (1989), cited below.
3. Harper, J.L. 1977. Population Biology of Plants. Academic Press, London. This beautifully written, comprehensive synthesis remains the classic treatise on plant population biology and its lessons apply to ecology in general. There is extensive discussion of many topics raised in this chapter, such as the concept of genets and ramets, clonality, and modularity.
