Other claims from this paper (8)
- Observation Metasequoia shows leaf anatomy characteristic of shade adapted plants.
- Observation Metasequoia leaf chloroplasts have well-developed grana in mesophyll and both epidermises.
- Observation Metasequoia is judged best adapted to low light intensities.
- Observation Sequoia and Taxodium have intermediate light adaptation.
- Observation Glyptostrobus is judged adapted to higher light intensities.
- Observation Metasequoia synthesized chlorophyll in complete darkness.
- Observation Metasequoia was stressed under high light.
- Mechanism The authors propose the leaf traits explain Metasequoia dominance at Eocene high latitudes.
