Turn in a drawing. One side of the page reflects the world in where

"The rule of that law was and is sufficient. Mankind was not needed to bring order to the world."-- Ishmael, pg 86

The other side is what the world looks like where man is the ruler.

 CHAPTER 6 POPULATION BIOLOGY powerpoint
Chapter Overview

The AP student needs to be competent in exponential and logistic growth curves
and the implications of each including the concept of carrying capacity. Type I, II
and III survivorship curves, characteristics of r and K -selected species, and
examples of each should be learned. Students need to know biotic and abiotic
factors in the environment and their role in determining population size.
Applications of conservation biology should be understood.

Key Concepts

6.1 Explain exponential growth and logistic growth.

6.2 Compare and contrast the factors that regulate population growth.

6.3 Summarize the characteristics of r-selected species and K-selected species.
Applications of Type I, II, and III survivorship curves

6.4. Understand the difference between density dependent and densityindependent
factors.

6.4 Identify some applications of population dynamics in conservation biology.
Use the Rule of 70 to calculate doubling time and growth rate.

Free-Response Question:
Directions: Answer all parts of the following question. Where explanation or
discussion is required, support your answers with relevant information and/or
specific examples. When a calculation is required, be sure to show how you
arrived at your answer.

1. The giant panda is an endangered species that lives in China. Answer the
following questions with regard to this endangered species.

(a) Identify and describe TWO reasons why the giant panda is endangered.

(b) Is the giant panda a K-selected species or r-selected species? Explain your
reasoning.

(c) In 2004, the population of giant pandas in the wild in China was 1600
individuals. If their growth rate is 1.0%, in what year will their population
exceed 3200 individuals?

(d) Describe TWO strategies that the Chinese government could employ to
insure that the population of giant pandas will continue to rise.
