Oct 31, 2023 · Differentiate among the ways in which species distribute themselves in space. Density and size are useful measures for characterizing populations. Scientists gain additional insight into a species’ biology and ecology from studying how individuals are spatially distributed.
These are known as random, clumped, and uniform distribution patterns, respectively (Figure 5.3). Different distributions reflect important aspects of the biology of the species; they also affect the mathematical methods required to estimate population sizes.
The normal approximation is a good approximation to patterns of variation seen in biology, economics, and many other fields. The following figure, from your texbook, shows distributions for (a) human body temperature, (b) university undergraduate brain size, and (c) numbers of abdominal bristles on Drosophila fruit flies:
