Abstract:
Mediterranean-climate annuals growing on serpentine soils in central California differ greatly in their life spans and reproductive periods dependent on their access to soil moisture. The longer-lived annuals accumulate a greater lifetime biomass, have a higher total, but lower proportional, reproductive output, and produce leaves with a higher C/N ratios at the time of reproduction.
