  1. Desert Life Notes

  2. Every drop of water counts Beat the heat Find food • Wax coated leaves minimize water loss (transpiration) • Deep roots tap into groundwater • Widely spread, shallow roots collect water after brief rain showers (water stored in spongy layer of cactus) • Drop leaves during long dry spells  dormant • Fast reproduction

  3. Tend to be small in size • Hide during the day, active at night/early morning • Get water from dew or food they eat • Become dormant during periods of extreme heat/drought • Many physical adaptations • Big ears  release body heat to cool down mammals • Thick outer covering to minimize water loss through evaporation (insects/reptiles) • Reduce water loss by having dry feces and excreting a dried concentrate of urine • Little to no hair

  4. Large desert cities • Soil destruction by vehicles or urban development • Livestock overgrazing • Land disturbance & pollution from mineral extraction (coal, oil, natural gas, etc) • Storage of toxic and radioactive wastes • Deserts recover VERY slowly • Slow plant growth • Very slow decomposition - recycling of nutrients for plants! • Low species diversity • Water shortages
