Aridness Page
: Aridness is typically measured using the Aridity Index , which calculates the ratio of annual rainfall to potential evaporation. Biological Resilience: "Weird" is Effective
: Larger organisms (macrofauna) are often more adapted to aridity than microbes, acting as the primary recyclers in hot, moisture-deprived habitats. The Urban Challenge aridness
: Some plants utilize high calcium levels to strengthen cell walls against desiccation or high salt concentrations to reduce water loss through transpiration. : Aridness is typically measured using the Aridity
