Criteria | Specie diversity | Ecological diversity |
Definition | Species diversity refers to the diversity observed at the species level in terms of effective abundance of different types of species in an area. | Ecological diversity refers to the diversity at ecosystem level in terms of variations in the ecosystems (such as deserts, forests, grasslands, wetlands and oceans) within a geographical location. |
Factors affecting the diversity | It is affected by latitudinal gradients and decreases as we move away from the equator towards the poles. | It is influenced by various biotic (organisms) and abiotic (temperature, humidity) factors. |
Examples | Western Ghats have a greater amphibian species diversity than the Eastern Ghats | India with diverse ecosystems found in its mangroves, deserts, rainforests, etc is said to be a highly ecologically diverse nation. |
