a long bush-whack up the back side of Granite Mountain via the Mint Wash trail is rewarded by a burbling creek where 95% of the time is a very dry canyon. I stop after three hours to turn back at a dense manzanita grove and fresh mountain lion scat. abiotic, biotic factors. suggesting that more hostile stress-inducing environments drive rapid and broader speciation… (latitudinal diversity gradient…)
Species richness through time may correlate with energy. The species richness – energy relationship posits correlations with evapo-transpiration, temperature, or productivity, and studies of terrestrial and marine ecosystems have shown that these factors may explain as much as 90% of current diversity, although relationships between species diversity and productivity change with spatial scale.
adaptive radiation — the absorption and expression of life-energies in an energy-rich environment energy availability in a usable form (a form developing based on energy availability)…
