Numerical Problems - Biodiversity
Here are some numerical problems based on the principles of biodiversity and conservation, focusing on the species-area relationship.
The species-area relationship is given by the equation log S = log C + Z log A. If the value of the regression coefficient (Z) is 0.2, the Y-intercept (C) is 0.5, and the area (A) is 100 square kilometers, what is the species richness (S)?
Solution:
Therefore, the species richness (S) is approximately 1.26.
In a study of a forest ecosystem, it was found that the species richness (S) is 10 when the area (A) is 1000 square kilometers. If the Y-intercept (C) is 2, what is the value of the regression coefficient (Z)?
Solution:
Therefore, the value of the regression coefficient (Z) is approximately 0.233.
For a particular group of organisms, the species-area relationship is described by the equation S = 5A0.3. If the area is increased from 100 km² to 200 km², what is the percentage increase in species richness?
Solution:
Therefore, the percentage increase in species richness is approximately 23.08%.
