For instance, long-term viability (persistent seed bank in the soil) can be predicted on seed morphological traits (size and shape) as suggested by Thompson, K., Band, S. R. & Hodgson, J. G. (1993) Seed size and shape predict persistence in soil. Functional Ecology 7: 236-241.

A newer approach adds a probabilistic model, see these two:
