Background and Aims Dry fruits remain around the seeds at dispersal in a number of species, especially the Brassicaceae. Explanations for this vary, but usually involve mechanisms of innate dormancy. We speculate that, instead, a persistent fruit may give additional protection through control of dehydration, to species growing in arid or Mediterranean environments where water is sporadic. Me…
Abstract Questions: Does altered flow timing affect seed bank dynamics within river margins of agricultural areas? Are seed banks of degraded riparian zones important for contributing to native riverine plant diversity? Location: Murray-Darling Basin, SE Australia. Methods: We surveyed the seed banks of five lowland rivers, three of which have large dams that alter the seasonal timing of flo…
