Populations (Ecology)
â¢Whatâs the difference between a cohort and static life table and what are the difficulties with each? Be able to interpret data in a life table.
⢠Be able to draw or interpret survivorship curves for different populations. What are the differences between the three types?
⢠Why does population age structure matter?
⢠What happened to Pablo Escobarâs hippos? What are some possible consequences? What might happen in the future?
⢠What are exponential and geometric growth?
⢠Be able to graph population size over time for a given growth rate (like figure 10.11).
⢠Whatâs the difference between density dependent and density independent factors to limit growth? Give examples. Which one regulates population size? Why?
⢠What is logistic growth? Explain how the growth rate changes at different population sizes. Be able to compare logistic and exponential growth.
⢠What are the four factors that affect population size over time?
⢠What are population cycles? What are some of the factors that drive them?
⢠What is delayed density dependence and why does delayed density dependence cause populations to fluctuate? What factors affect these fluctuations? Be able to draw typical population fluctuation figures like fig. 11.10.
⢠Whatâs the difference between stabilizing and destabilizing feedbacks? How do delayed feedbacks affect a stabilizing feedback?
⢠How does population size affect the likelihood of extinction?
⢠What is the Allee effect? How does it affect growth rate at different population densities? Draw a figure illustrating this.
