Since Darwin (1859), ecologists and evolutionists have assumed that the features of plants are adaptive, that is, they perform a specific function which increases their overall fitness and are the result of natural selection. A large body of literature

Coevolutionary processes tended towards more and more specifity, thus creating increased species diversity. Most serious parasites of useful plants such as crop rusts

Agricultural experience has underlined the debilitating effects that parasitic plants, nematodes, fungi, bacteria and viruses may have on host plants, but this provides little guide to their importance in the far more diverse

However, our understanding of the driving forces in the evolution of functional groups is still fragmentary and the discussion therefore often con

Although change is the rule in nature, the present speed of habitat destruction and global climatic change are unlikely to have occurred ever during the 400 million years since land plants evolved (e.g., Huntly 1991). Thus, there is litt
