Description: A general principle of adaptive allocation was proposed by Cody (1966) who hypothesized that 1) all living organisms have finite resources to partition among growth and competing physiological processes such as reproduction and defense; and 2) natural selection results in the evolution of unique resource allocation patterns that maximize fitness in different environments. Today, it is well established that plants have limited resources to allocate among these processes (Bazzaz et al. 1987), and theories of life-history strategy rests on the assumption that there are fitness trade-offs associated with varying patterns of resource allocation (Steams 1976, 1989, Reznick 1985, Bazzaz et al. 1987, Lovett Doust 1989). Trade-offs occur when an increase in resources allocated to one fitness component, such as growth, reduces the allocation to another, such as reproduction. Natural selection (acting within phylogenetic, physiological, and ecological constraints) should shape patterns of resource allocation, balancing the costs and benefits associated with these trade-offs, resulting in the evolution of life- history strategies maximizing fitness. There are direct and indirect costs associated with allocation to "nongrowth" processes such as reproduction. Direct costs are energy and assimilates invested in reproductive structures. Indirect costs are unrealized growth and future reproduction as a result of this investment (Bazzaz and Reekie 1985, Bloom et al. 1985, Bazzaz et al. 1987, Reekie and Bazzaz 1987c, Ronsheim 1988, Lovett Doust 1989).
