Species Area relationship is described by the following equation.
log S = log C + Z log A
where Z is:
1. Area
2. Species richness
3. Slope of the line
4. Y-intercept
(a) | Plants | (b) | Invertebrates |
(c) | Fishes | (d) | Mammals |
(e) | Birds |
1. | (a) > (b) > (e) > (d) > (c) | 2. | (a) > (c) > (d) > (b) > (e) |
3. | (b) > (a) > (e) > (d) > (c) | 4. | (b) > (a) > (c) > (e) > (d) |
According to Alexander von Humboldt :
1. | Species richness decreases with increasing area of exploration |
2. | Species richness increases with the increasing area, but only up to a limit |
3. | There is no relationship between species richness and the area explored |
4. | Species richness goes on increasing with increasing area of exploration |
Alexander Von Humboldt described for the first time:
1. Laws of limiting factor
2. Species-Area relationships
3. Population Growth equations
4. Ecological Biodiversity
