Survivorship can vary among individuals and among populations of the same species. Grazing can change survivorship patterns differentially as well of individuals alive indiff as theage specific survival age mortality. Life tables provide data on the classes in a population rates. Dx static life tables provide a snapshot of a population"s age structure from a a giventime alive sample startof theyear number that died during that year.
