To Estimate Which Age Cohort in a Population of Females

question 17

Essay

To estimate which age cohort in a population of females produces the most female offspring, you need information about the number of offspring produced per capita within that cohort and the number of individuals alive in the cohort. Make this estimate for Belding's ground squirrels by multiplying the number of females alive at the start of the year (column 2 in Table 53.1 from your textbook)by the average number of female offspring produced per female (column 5 in Table 53.2 from your textbook). Draw a bar graph with female age in years on the x-axis (0 -1, 1-2, and so on)and total number of female offspring produced for each age cohort on the y-axis. Which cohort of female Belding's ground squirrels produces the most female young?
