Next Monday, there will be a midterm on both the economics and the ecology topics covered thus far. In addition to reviewing the study questions, you should be familiar with the following questions/concepts.

1. What are ecological guilds and what is their importance in ecosystem functioning?

 

 

2. Be ready to identify the following species: Abies amabilis, Acer macrophylla, Alnus rubra, Picea sitchensis, Pseudotsuga menziesii, Thuja plicata, Tsuga heterophylla, Tsuga mertensiana, Arctostaphylos uva-ursi, Gaultheria shallon, Mahonia nervosa, Vaccinium ovatum. Vaccinium parvifolium

 

 

3. What is global warming and what are the main causes behind it? How does forest ecology impact or is impacted by global warming?

 

 

4. How are nutrient cycles linked? Be specific.

 

 

5. Outline the changes that might take place in the hydrological cycle (both local and regional) as a rainforest is converted into savanna.

 

 

6. Outline a general sequence for secondary succession on a disturbed site. Explain where the plants involved are coming from and give some specific examples of how they are getting into the site. For each stage of succession, outline the selection pressures that move succession forward.

 

 

7. Which of the global nutrient cycles have humans impacted the most (C, N, S, water)?

 

 

8. If a free-living nitrogen-fixer consumes about 35 g of carbon to fix 1 g of N, how much carbon would have to be supplied to fix 45 kg (about 100 pounds) of nitrogen? Give your answer in kilograms and pounds.
