BIOL 1121: General Biology II Lab
Fall 2014
Abstract Mark and recapture is a method commonly used in ecology to estimate an animal population 's size. A portion of the population is captured, marked, and released. This lab provides methods that can be used to estimate a
provided additional information for a better interpretation of lichen diversity values in biomonitoring studies of air pollution.
Introduction This section is an introduction to the lab objectives and its practical uses. It should normally be 1 to 2 paragraphs in a short report. The primary functions of an introduction are to describe the objectives of this laboratory exercise. The section needs to introduce the lab function and background. Any new concepts and terminology need to be given as well. Last should be the objectives of the lab. Include what should be accomplished or learned through performing this experiment.
For example, what is gel filtration chromatography? What does egg white consist of? What were you trying to getting out of the egg white sample? What properties of the technique did make it suitable for your purpose? What did you expect from the results? Why did you fractionate the protein? What did you do with the fractionated protein?

Did the experiment showed expected results (when the experiment was not to answer the question)? For example, was the protein sample fractionated as expected and was the number of fractions you collected close to what you expected? If not, what could be the cause of the unexpected results? Describe the sources, or suspected sources of error. Describe all the problems in the procedure (how and why it did not work). What should you do in the next step? If the lab could be repeated, how should the procedure be changed to improve the
