Population dispersion: tis distribution patterns that show the spatial relationship b/t members of population within a habitat. Individuals of population can be distributed in 3 basic patterns: Age structure: shows the distribution of various age groups in a population (typically that of a country or region of the world) Generation time: it"s the average time b/t 2 consecutive generations in the lineage of a population.
