 * The clutch frequency (reproductive maturity of a female)
 * Number of eggs per clutch
 * Survival rate


 * Milkweed Bugs Unlimited

=Quizlet for Pop & Eco 6=

Be able to do the following:
 * Interpret or list factors that would influence reproductive potential of a population (for example: Milkweed bugs lay 20 eggs per clutch and 5 clutches in their lifetime.). (Page 29 of lab book)
 * Interpret or list influential biotic and abiotic limiting factors. (Pages 31-41 of lab book)
 * Be able to interpret population graphs and scenarios such as the graph at the bottom of the page and pages 31-41 of lab book.

Other helpful things to look at: Population Dynamics Graph
 * Review your note-taking sheet (Limiting Factors).
 * Review all lab sheets and homework we have had so far for investigation 6.
 * Check out Pop & Eco 6 wiki for videos & quizlet
 * 1) At what letter is the population having all of its needs met and few limits on its population?
 * 2) At what letter is the population stabilized?
 * 3) At what letter is the population experiencing a decline due to limiting factors.
 * 4) At what letter is the population at the height of its population growth?
