You will need to go back to the example you chose in PL-Q3 that best explains K as well as think about and understand how a natural population typically behaves to be able to fully answer this question. On a graph, what does a natural population reaching K look like relative to a modeled population? Does the modeled population (after 1962) reach K in your figure? What about the natural population (before 1962)? Is there more than one K on the graph? If not, explain why there is only one using your figure and ecological theory. If so, how much is the"new" K larger or smaller than the K before the model? Using concepts you are learning about population dynamics, explain how it is possible to have more than one K. Based on your figure, is the survival of the modeled population (after 1962) in jeopardy? What if it behaved like a real population? Be specific in your explanation and refer to your figure.

LAB 3 - Population Dynamics 67 Age-Structured Fish Populations Below is a set of data taken from the literature that gives the age-class composition of a population of Brook Trout (Solvelinus fontinalis) in the Eastern United States. Today, you will use the output of the Leslie Growth Model that projected the population through time using the average survivorship for each age class (P.) and age-specific projected fecundity (F.) in Table 2.2 and the density dependent (PI"). Table 3.2 Age-class distribution, total population size for Brook Trout (Salvelinus fontinalis) in the Eastern United States from 1949-1962 as well as average survivorship (P) and age-specific fecundity (F) for each age class (x).
