. With detailed answers and explanations for each chapter, students can strengthen their understanding and prepare confidently for exams. Ideal for CBSE and other board students, this resource will simplify your study experience.The relation between species richness and area for a wide variety of taxa turns out to be a rectangular hyperbola. Give a brief explanation.
Alexander von Humboldt, a German naturalist and geographer, has observed that within the specific region, species richness increased with increasing explored area, but only upto the fixed limit. According to the relation between species richness and the area for a wide variety of taxa (like angiosperms, fishes, birds, bats) gives a rectangular hyperbola. Their relationship shows a straight line on a logarithmic scale which is described by the equation:
log S = log C + z log A
Where, S= species richness; A= Area; z = slope of the line; C= Y- intercept
The value of z lies between 0.1 to 0.2 in any case of the taxonomic group or the region. If the analysis of species- area relationship is done among large areas like continents etc. then the slope of line would be much steeper (here the value of z ranges from 0.6 to 1.2).
