out and turn in your CAPTURE output files. (2 points)Use the output generated during the in-class exercise to answer the following questions (see the lab notes for help/hints):
How many individual animals were captured? (1 point)
How many animals were captured more than once? (2 points)
What percent of the animals caught on the fourth night were new captures (first time captures)? (2 point)
Which model did you use to estimate abundance? Explain this model in your own words (assumptions of the model). (3 points)
Can you tell if the the population closed, based on the selected model? Why or why not? another Hint: page 66-67 of the Wildlife Monograph by Otis et al 1978 continually referred to in the CAPTURE program. (2 points)
What is the estimated probability of capture at time 4 and at capture time 9? Why are they different or should they be different? Answer both questions and explain your answers. (4 points)
What is the estimated population size under the appropriate model? What is the approximate 95% confidence interval for this estimate? Answer both questions. (2 points)
Explain the difference between the model you choose for this assignment and M(b) and their assumptions in your own words. (2 points)

Answers to the questions. NOTE: Please include the question or a shortened version of the question with your answer. Also, answers should be typed and double spaced.
Hardcopy of your output file. NOTE: Open the output file in a word processor, "clean up" the output incorporating only the IMPORTANT information to interpret your answers for the questions above, and then print it. Using a small Courier font will help keep columns aligned. Alternatively, put the output into a table (in a word processor or spreadsheet) and print the table. Make sure all columns are aligned and identified. This does NOT have to be in JWM format.
