Title
Seed Wings in Relation to Seed Size in the Genus Spergularia
Anders Telenius; Peter Torstensson Oikos 1991. doi:10.2307/3545339
Other claims from this paper (5)
- Association Seed type was the strongest predictor of seed size.
- Observation Winged seeds excluding wings were larger on average than unwinged seeds.
- Association Heteromorphic species occurred most frequently in marshes, unlike the remaining species in sandy or rocky places.
- Mechanism The authors suggest variation in wing occurrence may reflect selection on seed size.
- Mechanism The authors conclude that heteromorphism may have evolved for differential dispersal where water dispersal matters.
