Biology 301

Form and Function in Animals

Laboratory on Size and Shape



    The purpose of this laboratory is to provide some practical experience in determining allometric relationships, and to expose you to some of the limitations of the techniques.
 

From Gulliver's Travels (by Jonathan Swift)


    Gulliver's Travels presents some classic examples of serious problems with allometric relationships!
 

    Examine the series of biological structures provided. Using ideas and techniques described in the lecture and discussion papers, examine at least two functionally important scaling relationships. Please make sure that the two relationships you examine are dimensionally different, ie. if one parameter is related to l1 then the other should be related to either l2 or l3. Calculate the allometric relationships for your chosen parameters, and discuss the significance of your results. Show all of your results. ALL reports must be passed in at the beginning of the laboratory the following week.
