Questions and Answers

Steeper slopes in the species-area relationship mean that

  • Species richness remains constant regardless of explored area.
  • Species richness is unrelated to explored area.
  • Species richness increases at a faster rate with increasing explored area. (correct)
  • Species richness decreases with increasing explored area.

    • What is the equation that describes the relationship between species richness and area on a logarithmic scale?

  • $log S = log C + Z log A$ (correct)
  • $log S = log C - Z log A$
  • $log S = log C \cdot Z log A$
  • $log S = log C / Z log A$

    • What is the range of values for Z in the species-area relationship?

  • 0.6 to 1.2

  • 0.1 to 0.2 (correct)
  • 0.4 to 0.6
