I. | Within a region, species richness decreases with increasing explored area. |
II. | The rectangular hyperbola represents the relation between species richness and area for angiosperm plants, birds, bats and freshwater fishes, for example. |
III. | Z represents the regression coefficient or the slope of the line. |
IV. | The value of Z lies in the range of 0.1 to 0.2 regardless of the taxonomic group or the region. |
V. | For frugivorous birds and mammals in the tropical forests of different continents, the slope is found to be 1.15. |
VI. | If the species area relationship is analysed for very large areas, the slope of the line is much steeper and Z value lies in the range of 0.6 to 1.2. |
