Other claims from this paper (8)
- Association Isoprene-emitting species had maximum temperatures for net photosynthesis about 1.8°C higher than non-emitters.
- Association Photosynthetic thermal response curves were 24% wider in isoprene emitters.
- Association Optimum photosynthetic temperatures did not significantly differ between emitter groups.
- Association Photosynthetic rates at the optimum did not significantly differ between emitter groups.
- Observation Modeled carbon costs of even strong isoprene emissions caused little reduction in the net carbon assimilation advantage at supraoptimal temperatures.
- Mechanism Biochemical limitations and stomatal conductance may jointly limit photosynthesis above optimum temperature.
- Mechanism Isoprene emission may be an adaptation to warmer thermal niches.
- Association Emitting species may fare better under global warming than co-occurring non-emitting species.
