Assignment:

1) For the model without termite mounds (Panel A), describe the change in vegetation biomass as rainfall decreases and as it increases. At what points do sudden shifts occur?

2) For the model with termite mounds (Panel B), describe the change in vegetation biomass as rainfall decreases and as it increases. At what points do sudden shifts occur?

3) How does the vegetation biomass at 0.5 mm/day of rainfall differ in the two figures? Explain what is contributing to this difference.

4) For each cycle (i) and (ii), why do you think the increases in vegetation biomass (blue arrows) occur at higher rainfall rates than the decreases in biomass (red arrows)? (In other words, why doesn't vegetation recover from drought at the same level of rainfall as when vegetation was lost?)

5) How might these models be used to determine how resources for conservation and land management should be allocated in arid or semiarid areas or to address climate change?
