II. Short Essay (70 points)
1. What is Ecology? Name the main levels of organization studied in Ecology.
(10 points)
2. What are the heat exchange pathways determine body temperature? (10 points)
3. Suppose you are studying a community of small mammals that live on the
boundary between a forest (dominated by C3 plants) and a grassland
(dominated by C4 grass). One of your concerns is to discover the relative
contributions of the grassland and the forest to the nutrition of small
mammals living between the two ecosystems. How can you use the stable
isotope analysis to answer the question? (10 points)
4. Draw a figure then answer the following question. Please make sure that
everything in the figures is properly labeled, including the x- and y-
axes.
(1) 3 types of survivorship curve. Humans would best be represented by
which of the curve? (8 points)
(2) Climate diagram. According to a region's climate siagram, how can we
distinguish dry vs. wet season of the region? (8 points)
5. If you were a manager od an exploited population, such as a commercially
important fish, what size of fish population would you want to keep in
order to gain the best annual yield? Why? (8 points)
6. What is a metapopulation? What message do ecologists learn from studies
of metapopulations? (10 points)
7. In Grime's classification of plant life history, what are the factors that
led to the development of distinctive strategies or life history among
plants? (6 points)
