Age and size structure in predator and prey populations

For the sake of convenience we commonly treat populations as though they were homogeneous units, comprised of genetically identical, even-aged organisms having indistinguishable developmental histories. Since such a practice is, with few exceptions, an offense against nature, we ought to devote attention to the effects of relaxing this assumption. The influence of genetic variation upon the predatory process is taken up in Chapter 11. Here I address the effects of variation in age and size in both predator and prey populations.
