What are the patterns of biodiversity
Answers
Answer:
Darwin noticed three distinctive patterns of biological diversity: (1) Species vary globally, (2) species vary locally, and (3) species vary over time. - different, yet similar, animal species inhabited separated, but similar, habitats around the globe.
Latitudinal Gradients
Species diversity decreased from equator towards poles.
The tropics harbor more species than temperate and polar regions.
For example, Colombia (near equator) has 1400 species of birds whereas New York(41 N) has 105 species, Greenland(71 N) has 56 species and India(equator region) has 1200 species.
Species-Area Relationship
Alexander Von Humboldt has observed that within a region, species richness gets increased when explored area is increased, but only up to a limit.
The relationship between species richness and area for a number of taxa like angiospermic plants, fresh water fishes and birds is found to be a rectangular hyperbola.
