Other claims from this paper (8)
- Observation Heathy open-forest and heathland overstoreys grew during summer, producing large leaves and long internodes.
- Observation Savanna and rainforest overstoreys grew during spring and autumn.
- Association Reduced solar radiation was associated with reduced leaf area development in nutrient-rich understoreys.
- Observation Understorey foliage shoots showed little change in leaf specific area and internode length, except in cool Nothofagus forest.
- Observation Understorey plants in nutrient-poor ecosystems produced small leaves and short internodes.
- Mechanism Compact leaves increased stem-air interface temperature under direct solar radiation and still air.
- Mechanism Increased stem-air temperature induced earlier shoot growth and flowering in understorey shoots.
- Mechanism The authors interpreted these foliage attributes as an evolutionary response optimizing photosynthesis on nutrient-poor soils.
