Corals form the foundation for coral reef ecosystems and contain symbiotic dinoflagellates which greatly contribute to reef primary productivity. Loss of dinoflagellates from animal (host) cells results in cnidarian bleaching which leads to decreased coral fitness, and reef deterioration. Elevated temperature, caused by global warming, is the primary environmental stressor...

Numerical diversity indices measure one or both components.
Archaeologists use assemblage diversity to infer behavior
of prehistoric cultures.
Archaeological inferences about behavior...
