Typically, bears spend the majority of their time over productive waters associated with the continental shelf. A completely uniform distribution has maximal dispersion, a randomly scattered population has intermediate dispersion, and an aggregated population with clumps of individuals surrounded by empty space has minimal dispersion (Figure 3.1).
