Chapter 4 Population Biology

And Chapter 5 Biodiversity and Conservation Expectations 

By the end of the unit you should have the following completed:

 

1.     Be able to define and give an example when appropriate of:

Group A:  exponential growth, carrying capacity, density dependent factor, density independent factor, competition, predation, population density

Group B: natality, mortality, immigration, emigration

Group C:  biodiversity, endangered species, extinct species, threatened species, habitat fragmentation, edge effect, acid precipitation, exotic species

Group D:  conservation biology, sustainable use, reintroduction programs

2.     All assigned reading should be read with the goal of being able to discuss/explain the information contained in them.

Section 4.1  Population Dynamics              Section 4.2 Human Population Growth

Section 5.1 Vanishing species

3.     Have the following expectation questions answered in a complete sentence on a separate piece of paper:

Group 1  questions 

  1. How are graphs of exponential growth and linear growth different?

  2. Describe how density-dependent and density-independent factors regulate population growth.

  3. How can density-independent factors, such as a flood, influence carrying capacity?

  4.  An organic farmer does not use pesticides on her farm.  Instead of growing one crop on her harm, as many farmers do, she grows ten different crops.  Explain how this may decrease insect damage to her plants.

Group 2 questions

  1.  Discuss some possible problems for local populations caused by immigration and emigration of people.

  1.  How are limiting factors related to carrying capacity?

  2.  In what way is population density an important factor in determining carrying capacity?

  3. How have humans disrupted homeostasis of our population?

Group 3  questions 

  1. What are two causes for a species to become threatened or endangered?

  2. How does acid precipitation kill trees?

  3. What is an edge effect?

  4. How do exotic species affect populations of native species?

  5. Suggest reasons why warm tropical areas have more biodiversity than cooler areas.

  6. How does the number of types of organisms in an ecosystem relate to the stability of that ecosystem?

  7. What happens to the concentration of biocide in the members of a food chain.

  8. Why is maintaining biodiversity important?

4.     Labs to be handed in with discussion questions written out and answered in complete sentences:

Population Growth Lab                    Population Density Lab

Problem solving lab 4-1                    Minilab 4-2

Problem solving lab 5.1 Interpreting data p. 119

5.     Assigned graphing exercises and be able to correctly graph according to the given procedure.  Click on the link for more information on graphing.

6.     Be able to predict the size of a population given natality, mortality, immigration and emigration information.  Click on the link for more information on how to do population problems.

7.     Know how to convert from one unit to another in the metric system using factor label method.

8.     Know all the metric prefixes, their meanings and how they are related to one another.

9.     Record all material presented in class notes and commit them to memory.

 

 Extra Credit: Students eligible for this extra credit have all of their assigned work turned in/checked on time for the chapter.  This assignment must be passed in before the test is taken  (maximum 3 pts on test)

 

Individuals of certain species have been dispersed to new areas with dramatic consequences to both the population and the area in which the species is introduced.  Research what happened to the following:

The European starling after it was introduced to the United States

The pig after it was introduced to the Hawaiian Islands

The African Bee after it was introduced to South America

The Prickly pear cactus after it was introduced to Australia.

Write a well constructed one-page paper explaining your findings for each topic you choose to research.  Your paper must be typed, 12 pt. Font, no more than 1 inch margins on any side.
