And letâs face it: the Hollywood version of Revenge of the Mummy would be no great loss. Originally built in 2004, itâs a shadow of its Universal Studios Florida counterpart.
This variety can be measured on several different levels. Genetic-variation between individuals of the same species. This includes genetic variation between individuals in a single population, as well as variations between different populations of the same species. Genetic differences can now be measured using increasingly sophisticated techniques. These differences are the raw material of evolution.
Two important measures of a population are population size, the number of individuals, and population density, the number of individuals per unit area or volume. Ecologists often estimate the size and density of populations using *quadrats * and the mark-recapture method. A population can also be described in terms of the distribution, or dispersion, of the individuals that make it up. Individuals may be distributed in a uniform, random, or clumped pattern. Uniform means that the population is evenly spaced, random indicates random spacing, and clumped means that the population is distributed in clusters.
