Population Ecology

1. Explain the following ecological terms: Individual, Population, Community, and Ecosystem. Put the terms from simplest to most complex order.

2. Geographic distribution of a population is influenced by what factors? What is composed of a community in an area? What is studied by an Ecosystem ecologist in a region?

3. What are three distribution patterns? Define each with examples. Which distribution pattern is encountered most?

4. Studies on predator-prey relationship, studies on interactions of different populations (species) and their surrounding environment fall into which level of ecological study?

5. What do you mean by density-independent and density-dependent factors that limit human populations? What are the examples?

6. How is population measured? Why ecologist use sample to determine the whole population?

7. How does the exponential and logistic growth differ? Under what condition populations experience exponential growth and under which conditions logistic growth?

8. How is growth rate of a population measured?

9. What is carrying capacity? What happens to a population when it reaches its carrying capacity?

10. What are biotic and abiotic factors, and density-dependent and density-independent factors? How these factors effect population.

11. DNA analysis can document what characteristics of a population? Urine, bone remains and wolf scat are useful in assessing what aspect of a population?
