Document Summary
Answer: all individuals can be counted the same. Structured populations: if we think age or size is important to understanding a population, we might model it as an structured population, instead of just keeping track of the total number of individuals in our population . Keeping track of how many individuals of each age. 1. 1 example: biennial dandelions: imagine a population of dandelions. 1% of seeds survive to become adults. 50% of rst-year adults survive to reproduce again. How to study this population: choose a census time. Since we have complete cycle information, either one should work: figure out how to predict the population at the next census. We want to know how many adults we will see next year: after reproduction. Two-year-olds have already produced their seeds; once these seeds are counted, the two-year-olds can be ignored, since they will not reproduce or survive again. Answer: 0. 5 for 1-year-olds and 0 for 2-year-olds.
