Question

Discuss two reasons for estimating vm of animal populations in their natural ecosystems. What are "sampling" and "estimation" and how are the two concepts related? Discuss the four major assumptions on which the mark-recapture method is based. What kinds of problems would cause these assumptions to be violated? What kinds of organisms (e.g., plants, animals, etc.) can (and cannot!) have their populations estimated using this technique? Why did you calculate the standard error of the estimated population size? Generally, what do the standard error and confidence limits tell you? Discuss how you could reduce the standard error of your estimate for "your" disk population and for a real population of animals. Look at the class data. How many times did a group's confidence interval fail to "capture" the true population size? Is this surprising? Explain.

Explanation / Answer

1) One reason for studying population size in natural ecosystems is , at first population grows fast becuase of the availability of resources.So it will be known to us how the population size will be when the resources are full.

The second reason for studying population size in natural ecosystems is ,once the population increases there will be competition for resources and the resources will become scarce ,consequently the population will decrease and it will known to us how the population size will be when the resources are scarce.
