Year to year variability in survivorship for the summer annual Erucastrum gallicum

This figure shows survivorship curves for spring cohorts of the summer annual plant Erucastrum gallicum (Brassicaceae) growing in the Jamesville Quarry, Syracuse, NY. It shows how survivorship varies markedly from year to year, due mainly to variability in rainfall. Survivorship approximated a Deevey Type I function in 1976, a year with abundant rain. Survivorship followed a Type III pattern in 1977 due to heavy seedling mortality during a spring drought. Survivorship resembled a Type II pattern in 1978 - a year with alternating periods of drought and abundant rain.
