Clutch size, offspring performance, and intergenerational fitness

摘要: © 1994 International Society for Behavioral Ecology It is now generally recognized that clutch size affects more than offspring number. In particular, a suite of traits associated with reproductive performance. Optimal therefore determined not by the numerically most productive but maximizes collective success. Calculation optimal thus requires consideration ecological factors operating during an intergenerational time frame, spanning lifetime egglaying adult and lifetimes her offspring. The cannot define values in advance, instead strategy chosen best response to set it itself generates. this article, we introduce methods solving problem, based on iterative solution equation characterizing expected We begin considering semelparous organism, which case success function only state organism. For iteroparous depends upon both time, so our extend usual stochastic dynamic programming approach evaluation are intuitive easily used. consider organisms, stable varying environments, describe how can be employed empirically.
