Weak tradeoff between xylem safety and xylem‐specific hydraulic efficiency across the world’s woody plant species

Gleason, S. M., Westoby, M., Jansen, S., Choat, B., Hacke, U. G., Pratt, R. B., Bhaskar, R., Brodribb, T. J., Bucci, S. J., Cao, K.-F., Cochard, H., Delzon, S., Domec, J.-C., Fan, Z.-X., Feild, T. S., Jacobsen, A. L., Johnson, D. M., Lens, F., Maherali, H., Martínez-Vilalta, J., Mayr, S., McCulloh, K. A., Mencuccini, M., Mitchell, P. J., Morris, H., Nardini, A., Pittermann, J., Plavcová, L., Schreiber, S. G., Sperry, J. S., Wright, I. J. and Zanne, A. E. (2016), Weak tradeoff between xylem safety and xylem-specific hydraulic efficiency across the world's woody plant species. New Phytol, 209: 123–136. doi:10.1111/nph.13646

Summary The evolution of lignified xylem allowed for the efficient transport of water under tension, but also exposed the vascular network to the risk of gas emboli and the spread of gas between xylem conduits, thus impeding sap…

Paleo-Antarctic rainforest into the modern Old World tropics: The rich past and threatened future of the “southern wet forest survivors”

ABSTRACT • Premise of study: Have Gondwanan rainforest floral associations survived? Where do they occur today? Have they survived continuously in particular locations? How significant is their living floristic signal? We revisit these classic questions in light of significant recent…

Hydraulic tuning of vein cell microstructure in the evolution of angiosperm venation networks

Feild, T. S. and Brodribb, T. J. (2013), Hydraulic tuning of vein cell microstructure in the evolution of angiosperm venation networks. New Phytol, 199: 720–726. doi:10.1111/nph.12311

Summary High vein density (DV) evolution in angiosperms represented a key functional transition. Yet, a mechanistic account on how this hydraulic transformation evolved remains lacking. We demonstrate that a consequence of producing high DV is that veins must become very…

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…

Evolution of stomatal responsiveness to CO2 and optimization of water-use efficiency among land plants

Brodribb TJ, McAdam SAM, Jordan GJ, Feild TS. 2009. Evolution of stomatal responsiveness to CO2 and optimization of water-use efficiency among land plants. New Phytologist 183(3): 839-847.

The stomata of angiosperms respond to changes in ambient atmospheric concentrations of CO2 (Ca) in ways that appear to optimize water-use efficiency. It is unknown where in the history of land plants this important stomatal control mechanism evolved….

Giant Flowers of Southern Magnolia Are Hydrated by the Xylem

Feild TS, Chatelet DS, Brodribb TJ. 2009. Giant flowers of southern Magnolia are hydrated by the xylem. Plant Physiology 150(3): 1587-1597.

Flowering depends upon long-distance transport to supply water for reproductive mechanisms to function. Previous physiological studies suggested that flowers operated uncoupled from stem xylem transport and received water primarily from the phloem. We demonstrate that the water balance…

Viewing leaf structure and evolution from a hydraulic perspective

Brodribb TJ, Feild TS, Sack L. 2010. Viewing leaf structure and evolution from a hydraulic perspective. Functional Plant Biology 37: 488-498.

More than 40 000 km3 year–1 of water flows through the intricate hydraulic pathways inside leaves. This water not only sustains terrestrial productivity, but also constitutes nearly70%of terrestrial evapotranspiration, thereby influencing both global and local climate (Chapin et…

Fossil evidence for low gas exchange capacities for Early Cretaceous angiosperm leaves

Feild TS, Upchurch GR, Chatelet DS, Brodribb TJ, Grubbs KC, Samain MS, Wanke S. 2011. Fossil evidence for low gas exchange capacities for Early Cretaceous angiosperm leaves. Paleobiology 37 (2): 195-213

The photosynthetic gas exchange capacities of early angiosperms remain enigmatic. Nevertheless, many hypotheses about the causes of early angiosperm success and how angiosperms influenced Mesozoic ecosystem function hinge on understanding the maximum capacity for early angiosperm metabolism. We…

Fossil evidence for Cretaceous escalation in angiosperm leaf vein evolution

Feild, T. S., T. J. Brodribb, A. Iglesias, D. S. Chatelet, A. Baresch, G. R. Upchurch, Jr., B. Gomez, B. A. R. Mohr, C. Coiffard, J. Kvacek, and C. Jaramillo. 2011. Fossil evidence for Cretaceous escalation in angiosperm leaf vein evolution. Proceedings of the National Academy of Sciences 108 (20): 8363-8366.

The flowering plants that dominate modern vegetation possess leaf gas exchange potentials that far exceed those of all other living or extinct plants. The great divide in maximal ability to exchange CO2 for water between leaves of nonangiosperms…

Global convergence in the vulnerability of forests to drought

Choat B, Jansen S, Brodribb TJ, Cochard H, Delzon S et al. (2012) Global convergence in the vulnerability of forests to drought. Nature 491: 752–755

Shifts in rainfall patterns and increasing temperatures associated with climate change are likely to cause widespread forest decline in regions where droughts are predicted to increase in duration and severity. One primary cause of productivity loss and plant…
