What is the range of Z values according to the species:area relationship analysis?
What is the range of Z values according to the species:area relationship analysis?
0.1 to 0.2
0.6 to 1.2
1.15
0.0 to 1.0
Solution
The value of Z, the slope of the regression line, lies in the range of 0.1 to 0.2 for different taxonomic groups and regions, regardless of whether it's the plants in Britain, birds in California, or molluscs in New York state. The species:area relationships among very large areas, such as entire continents, have a much steeper slope, with Z values in the range of 0.6 to 1.2.
