Career
In his famous 1947 paper, he defined "life zones" using three indicators:
- Mean annual biotemperature (average temperature, after data values below 0 °C or above 30 °C have been eliminated)
- Total annual precipitation
- The ratio of mean annual potential evapotranspiration to mean total annual precipitation.
Holdridge participated in the Cinchona Missions, a United States effort to search for natural sources of quinine during World War II.
