PROF. MADISON Biology of Organisms March 26, 2007 EXAMINATION II (Lectures 9-17) Follow these DIRECTIONS for full credit : 1. On top left side of answer sheet, write LAST NAME, skip one blank space, then FULL FIRST NAME. 2. Write the last 4 digits of your SSN in area marked “identification number” (columns A-D). 3. 4. Write your name and grad TA’s name on this sheet in spaces below. 5. After the exam , read and sign the following statement and turn in both the answer sheet and exam. By signing below, I give my word that I have neither cheated on this exam, nor have I knowingly allowed any other person to cheat on this exam. NAME_________________________________ Grad TA______________________________ Signature_______________________________ Exam directions : There are 40 questions on the exam; alert proctors if there are missing pages. Always read all answer choices carefully before choosing the best answer based on Bio 117 course material. 1. Give the correct answer below, giving first the population growth model that has a constant “r”, and second the population growth model that is density independent: A. Logistic Growth Model, Logistic Growth Model B. Exponential Growth Model, Exponential Growth Model C. Exponential Growth Model, Logistic Growth Model D. Logistic Growth Model, Exponential Growth Model 2. Identify the correct statement regarding “K”: A K for a population is constant across different habitats B . K can be different for two species living in the same environment C. K is the intrinsic rate of population increase D. All populations eventually reach and stay at K 3. Concerning text data for the lizard Lacerta vivipara , give the most correct statement below: A. Viviparity in this species is most associated with populations at lower elevations and latitudes B. The youngest reproductive lizards had the highest fecundity per capita C. The younger reproductive age classes made a greater contribution to population growth D. All the above are correct 4. Give the best answer: A. Probably the greatest conservation concern having to do with animal metapopulations is that the subpopulations become so isolated from each other that gene flow is no longer effective in reducing the often deleterious effects of genetic drift and inbreeding. B. Hudson’s research on red grouse showed that when drugs were given to kill intestinal nematodes, the populations were no longer limited in their population growth C. According to the General Adaptation Syndrome, populations of animals experiencing stress at high densities over long periods of time are likely to show over-stimulation and enlargements of their pituitary, reproductive and digestive glands, which can lead to organ failure and death. D.
