A plurality of causal mechanisms explains the persistence or transience of soil seed banks

, : A plurality of causal mechanisms explains the persistence or transience of soil seed banks. Journal Of Arid Environments: 2, 303-306

Annual forbs form short-term persistent soil seed banks whereas perennial grasses form mostly transient ones in the central Monte desert. A conceptual framework predicts that annual forb seeds will have primary dormancy, whereas perennial grasses will have low dormancy levels. We assessed whether the dormancy traits of four annual forb species and five perennial grass species can account for their soil seed bank dynamics.
