  • founded on physiological requirements of organisms. (sunlight and temperature)

Water also influences plant productivity. Productive areas can support higher species diversity and thus it acts a  strong predictor of global extent geographical variation in species richness of terrestrial birds. ]]> 2018-03-22 01:08:35 UTC https://padlet.com/bs16110360/productivity/wish/244806520 Water-Energy Dynamics bs16110360 https://padlet.com/bs16110360/productivity/wish/244806797
  • operate via plant productivity
  • latitudinal shift from ambient energy in far North to water toward the tropics
  • high latitudinal area ( ambient energy)
  • low latitudinal area (water-related variables - AET & annual rainfall)

The adaptation to one habitat would result in competitive inferiority - limited resources . Landscapes where distinct habitats can support different species results in high diversification when specialist exhibit distinct habitat preference.
