Question
Describe with an example the latitudinal gradients of biodiversity.
✓
Answer
- Species diversity decreases as one moves away from the equator towards poles.
- In general tropics (latitudinal range of 23.5°N to 23.5°S) harbour more species than temperate or polar regions, because they have constant environments and more solar radiation.
- e.g. Colombia located near the equator has about 1400 species of birds whereas New York (41°N) has only 105 species and Greenland (71°N) has only 56 species of birds.
