WLF 448: Fish & Wildlife Population Ecology
Lab Notes 4, Fall 2004

Problem Set #4:

Mapping a Species' Distribution Part 2

Delineate the distribution of either the mountain lion or black-chinned hummingbird. In other words, repeat the in-class exercise but use the mountain lion or black-chinned hummingbird in the species_info file.  .

 

 

Answer the following questions:

1.

Do you think the species distribution map you created is a good prediction of its actual distribution?  Why or why not? How would the biology of the species influence its predicted distribution?  Do you think this distribution map could be improved?  If so, how? (4 points)

 

2.

List and describe any limitations/problems with the vegetation and hexagon data you used.  How might these limitations (if any) influence the interpretation of the data and any conclusions drawn from your predicted species distribution? (3 points)

3.

Compare and contrast a deductive model vs. inductive model vs a combination of both for building a species distribution.  Which do you think is a better model and why? (3 points)

 

4.

How is time incorporated into a species distribution model? Does it need to be more explicitly addressed? (2 points) 

5. Provide 2 examples of how this species distribution could be used in population ecology?  Include what kind of data would be needed and the importance of your application. (4 points)

Turn in the following (due next week at the beginning of lab):

          Read directions carefully!

  1. A map of either the mountain lion or black-chinned hummingbird distribution in Idaho (4 points). The map does not have to be in color. Note: If you run into trouble printing and cannot resolve the problem, turn in a copy of your project (*.apr) on a 3.5"HD diskette. Be sure to label your diskette with your name, lab section, and file name.

  2. Answers to the 5 discussion questions listed above (16 points). REMEMBER: answers must be typed and double-spaced. Points will be deducted for improper grammar, spelling errors, and poor organization. Make sure your name and lab-section number are on the front page. Place your map after your answer page(s). Please staple your pages with 1 staple in the upper-left corner. We are not responsible for the loss of pages that are turned in loose.
