Document Summary

Bio120 lecture 18 population ecology: models without age structure. Definition of population vs individuals: population = the # of individuals of a species in a defined area, referred to as n, population count = the number n. Larkspur = a unique plant where each unique seed produces a new unique individual: e. g. Aspen = huge clonal groves; the large patches of clones are connected. Many physiological individuals but only counts as 1 genetic individual: e. g. Dandelions = many seeds produce identical but unconnected plants; no sex is required for seeds; seeds are clones of mothers. Physically separate plants that are still genetically identical: there aren"t that many scientists going around counting animals / plants. Dominated by mathematical theory to model populations. Exponential & geometric population growth models (density independent): goal of production models, model how numbers change through time (y axis = numbers, x axis = time)
