Explorations of range edges have been historically somewhat divorced from studies of geographical variation in population size. The emerging data on patterns of abundance across entire species' ranges and modeling work predicting patterns of abundance under different dispersal and oceanographic scenarios both suggest that it could be fruitful to further study the potential for dispersal to influence geographic patterns of population size. In examining these three issues, the chapter stresses the value of a multifaceted approach to macroecological studies. These insights were gained by a combination of empirical documentation of large-scale patterns for different life history groups, modeling efforts, and critical examinations of mechanistic hypotheses.
