Angiosperm leaf vein evolution was physiologically and environmentally transformative.

Boyce CK, Brodribb TJ, Feild TS, Zwieniecki MA. 2009. Angiosperm leaf vein evolution was physiologically and environmentally transformative. Proceedings of the Royal Society of London Series B 276: 1771-1776.

The veins that irrigate leaves during photosynthesis are demonstrated to be strikingly more abundant in flowering plants than in any other vascular plant lineage. Angiosperm vein densities average 8 mm of vein per mm2 of leaf area and…

Measurements of stem xylem hydraulic conductivity in the laboratory and field

Melcher, P.J., N.M. Holbrook, M.J. Burns, M.A. Zwieniecki, A.R. Cobb, T.J. Brodribb, B. Choat and L. Sack. 2012 Measurements of stem xylem hydraulic conductivity in the laboratory and field. Methods in Ecology and Evolution 3, 685-694.

Xylem hydraulic properties play an essential role in supporting growth and photosynthesis and influence sensitivity to environmental conditions such as drought and freezing. Consequently, stem hydraulic conductance can be used as a comparative measure of overall hydraulic adaptation…

Angiosperms helped put the rain in the rainforests: the impact of plant physiological evolution on tropical biodiversity

Boyce, C. K., J.-E. Lee, T. S. Feild, T. J. Brodribb, M. A. Zwieniecki. 2010. Angiosperms helped put the rain in the rainforests: The impact of plant physiological evolution on tropical biodiversity. Annals of the Missouri Botanical Gardens 97: 527-540

The recycling of transpired water is well known to be an important source of rainfall, particularly in the tropics, and angiosperms have transpiration capacities higher than any other plants throughout evolutionary history. Thus, the evolution and rise to…
