Study the graph given below:
As per Alexander von Humboldt, what do the symbols S, A, Z and C in the graph stand for, in respect of a species and area relationship?
उत्तर
On a logarithmic scale, the relationship is a straight line described by the equation,
log S = log C + Z log A
where,
S = Species richness
A = Area
Z = slope of the line (regression coefficient)
C = Y-intercept
