Figure 54.1 Many Populations Have Patchy Distributions The distribution and abundance of the herbaceous perennial Clematis fremontii are patchy over different spatial scales. (A) Populations occur within limestone meadows. A group of populations makes up a metapopulation, and multiple metapopulations make up the geographic range (in this case, Missouri, Kansas, and Nebraska). (B) Individuals within a population show one of three different dispersion patterns.
