Species-area relationship plot on log scale shows a __________.
Open in App
Solution
The correct option is C straight line
Alexander von Humboldt, a German naturalist and geographer, proposed the species - area relationships during his extensive explorations in the South American jungles. He observed that, within a region, species richness increased with increasing explored area, but upto a certain limit.
The relationship between species richness and area can be given by the equation
S = CAz
where S - Species richness
Z - Slope of line (regression coefficient)
C - Y-intercept
A - Area
On a logirithmic scale, it is given as
log S = log C + Z log A
Graphically it is represented as,
As seen above, the species-area plot is a rectangular hyperbola. On a log scale, the graph shows as straight line.
