Description
| - Area, energy available and latitude are the main factors influencing species richness: (1) species richness increases with area - the species-area relationship (SAR); (2) according to species-energy relationship (SER) the energy available to an assemblage; (3) there are more species per unit area in the tropics than in the temperate regions. We collected data on species richness of orchids for various areas in the world and calculated the mean Normalized Difference Vegetation Index (NDVI) as a measure of energy availability in these areas. We show that area considered is always very important, and that latitude is more important than energy available.
