Population Ecology		Name____________________________ # ______

1.	One species of forest bird is highly territorial, while another species lives in flocks.  Predict each species’ likely pattern of dispersion and explain advantages and disadvantages for each.

2.	Identify the types of survivorship curves shown in the image below.  Below the graph, give an example of each & describe the characteristics of species for each.

3.	In what way might high competition for limited resources in a predictable environment influence the evolution of life history traits?

       4. Distinguish between interspecific competition and intraspecific competition. Relate     	intraspecific to natural selection.						OVER 

4.	Explain why the life history of an organism cannot: 1) reproduce early and often; 2) produce large numbers of offspring; 3) have long lifespan.

5.	Compare & contrast exponential and logistic growth curves.  Explain the equation associated with each curve.

6.	Look at the graph below, what is the K for the population?

7.	Given: a species produces few, relatively large offspring each year. Make a claim regarding this as r-selected or k-selected. Justify the claim.

8.	Where is exponential growth by a plant population more likely:1) on a newly formed volcanic island, or 2) in a mature, undisturbed rain forest? Explain why.

9.	Identify three density dependent factors that may limit population growth.

10.	State 4-5 density independent factors that may cause population fluctuation.
