Chapter 8 Population Ecology
Identify the following. Be as specific as possible, and include names, dates, and
relevant facts as appropriate. Be sure to explain the significance of the term.
Core Case Study: Southern Sea Otter
Question 1: As the article describes, Southern Sea Otters peform
valuable ecological tasks in the marine community. Yet, anglers argue
that sea otters eat too many shellfish, thus affecting their profits. So,
fishermen and otters compete for food resources. How would you solve
this problem so that all parties involved are happy? Explain.
8.1 Population Dynamics and Carrying Capacity
a) Population dispersion
b) Age Structure
c) Biotic potential of a population
Question 2: The brown tree snake was accidentally introduced onto the
island of Guam in 1952. Since then, the snake has taken over the island,
killing numerous native bird species. Research another accidental
introduction that has occurred on an island and discuss the impacts that
have occurred because of this introduction.
8.2 Reproductive Patterns
d) Asexual vs sexual reproduction
e) Life table
Question 3: Given current environmental conditions, would you rather be
an r-strategist or a k-strategist? Explain with reasoning.
Question 4: Can we continue to expand the earth's carrying capacity for
humans? Explain.
Question 5: Explain why a simplified ecosystem such as a cornfield
usually is much more vulnerable to harm from insects and plant diseases
than a more complex, natural ecosystem such as a grassland. Does this
mean we should never convert a grassland into a cornfield (too late  )?
Question 6: Research one animal species not discussed in the book.
Identify its reproduction strategy (k or r), life expectancy, and limits on its
growth.
