Title
Evolutionary responses of stomatal density to global CO2 change
DAVID J. BEERLING; WILLIAM G. CHALONER Biological Journal of the Linnean Society 1993. doi:10.1111/j.1095-8312.1993.tb02096.x
Other claims from this paper (4)
- Association Fossil Salix herbacea leaves showed lower stomatal density as CO2 rose over a glacial cycle covering 140,000 years.
- Association Herbarium tree leaves showed declining stomatal density as CO2 rose over the last 200 years.
- Mechanism The authors interpret long-term selection as possibly favoring a response similar to the shorter-term phenotypic response in trees.
- Recommendation The authors recommend considering natural selection when extrapolating short-term stomatal responses to long-term climatic and atmospheric change.
