The spatial aspect of population ecology can be more readily modeled than it can be tested and studied in the field. Two reports help redress the balance. Maron and Harrison (p. 1619) demonstrate experimentally how a host-parasitoid interaction can result in the patchy distribution of a population within a continuous habitat, a result predicted theoretically. Ranta et al. (p. 1621) used a 68-year record of the population size of Canadian lynx from eight provinces of Canada to investigate the dynamics of populations in time and space. Notable, but unstable, synchronicities occur, particularly among neighboring populations. These dynamics can be captured by a straightforward model of population dynamics, which suggests that there may be a simple explanation for the phenomenon.
