Other claims from this paper (10)
- Observation Hydroriparian species had smaller diaspores than xeroriparian species.
- Observation Hydroriparian and xeroriparian species formed persistent seed banks at approximately equal percentages.
- Observation Persistent seeds were smaller than transient seeds.
- Observation Persistent hydrophyte seeds were smaller than persistent xerophyte seeds.
- Observation Hydroriparian diaspores were abundant on wet channel bars and in deep floodplain soils.
- Observation Xeroriparian diaspores were mostly restricted to litter and upper soil in higher, drier floodplains.
- Association Viable diaspores became smaller with increasing depth in floodplain soils.
- Association Viable diaspores became rounder with increasing depth in floodplain soils.
- Association Plant composition shifted from xeroriparian to hydroriparian species with soil depth.
- Mechanism Wide distribution of hydroriparian diaspores increases the chance of ephemeral wetland communities after floods.
