Jonathan A. Myers and Kyle E. Harms. 2011. Seed arrival and ecological filters interact to assemble high-diversity plant communities. Ecology 92:676–686.

Appendix A (TABLE A1). Species, densities, and viability of seeds used in the seed arrival treatment. Thirty-one species added in the seed arrival treatment in 2007, showing dispersal type based on seed morphology, number of seeds added per 0.5 m2 subplot, and percent seed germination on petri dishes (N = 50 seeds/species; germination was not tested for H. gronovii).
