Weba measure of habitat similarity (see Exercise 2). Density, however, provides an incomplete assessment of how individuals are distributed within a habitat. Two different populations may have similar density values but different spatial patterns. In nature, there are three distribution patterns: random, regular (or uniform), and clumped.
