Murray's law, the ‘Yarrum’ optimum, and the hydraulic architecture of compound leaves

Creator:: McCulloh, Katherine A., Sperry, John S., Meinzer, Frederick C., Lachenbruch, Barbara, and Atala, Cristian
Abstract:: • There are two optima for maximizing hydraulic conductance per vasculature volume in plants. Murray's law (ML) predicts the optimal conduit taper for a fixed change in conduit number across branch ranks. The opposite, the Yarrum optimum (YO), predicts the optimal change in conduit number for a fixed taper. •...

Evaluating theories of drought-induced vegetation mortality using a multimodel– experiment framework

Creator:: McDowell, Nate G., Gehres, Nathan, Limousin, Jean Marc, Macalady, Alison, Martínez-Vilalta, Jordi, Mencuccini, Maurizio, Plaut, Jennifer A., Ogée, Jérôme, Robert E., Pangle, Rasse, Daniel P., Ryan, Michael G., Fisher, Rosie A., Sevanto, Sanna, Waring, Richard H., Williams, A. Park, Yepez, Enrico A., Pockman, William T., Xu, Chonggang, Domec, Jean-Christophe, Holtta, Teemu, Mackay, D. Scott, Sperry, John S., Boutz, Amanda, and Dickman, Lee
Abstract:: Model–data comparisons of plant physiological processes provide an understanding of mechanisms underlying vegetation responses to climate. We simulated the physiology of a pi~non pine–juniper woodland (Pinus edulis–Juniperus monosperma) that experienced mortality during a 5 yr precipitation-reduction experiment, allowing a framework with which to examine our knowledge of drought-induced tree mortality....

Development of a Multi-Criteria Decision Method for High-Speed Rail Corridor Evaluation

Creator:: Sperry, Benjamin R., Mueller, Jon, and Hunter-Zaworski, Katharine
Abstract:: High-speed intercity passenger rail projects are very complex and require many years of planning and environmental activities before construction can begin. Given the complexity of planning and environmental reviews associated with high-speed intercity passenger rail corridor planning, a systematic approach for high-level screening of various alternative routings for proposed high-speed...

Moving water well: comparing hydraulic efficiency in twigs and trunks of coniferous, ring-porous, and diffuse-porous saplings from temperate and tropical forests

Creator:: McCulloh, Katherine A., Sperry, John S., Lachenbruch, Barbara, Meinzer, Frederick C., Reich, Peter B., and Voelker, Steven
Abstract:: • Coniferous, diffuse‐porous and ring‐porous trees vary in their xylem anatomy, but the functional consequences of these differences are not well understood from the scale of the conduit to the individual. • Hydraulic and anatomical measurements were made on branches and trunks from 16 species from temperate and tropical areas,...

Comparative hydraulic architecture of tropical tree species representing a range of successional stages and wood density

Creator:: McCulloh, Katherine A., Meinzer, Frederick C., Sperry, John S., Lachenbruch, Barbara, Voelker, Steven L., Woodruff, David R., and Domec, Jean-Christophe
Abstract:: Plant hydraulic architecture (PHA) has been linked to water transport sufficiency, photosynthetic rates, growth form and attendant carbon allocation. Despite its influence on traits central to conferring an overall competitive advantage in a given environment, few studies have examined whether key aspects of PHA are indicative of successional stage, especially...

Testing the metabolic theory of ecology

Creator:: Price, Charles A., Weitz, Joshua S., Savage, Van M., Stegen, James, Clarke, Andrew, Coomes, David A., Dodds, Peter S., Etienne, Rampal S., Kerkhoff, Andrew J., McCulloh, Katherine, Niklas, Karl J., Olff, Han, and Swenson, Nathan G.
Abstract:: The metabolic theory of ecology (MTE) predicts the effects of body size and temperature on metabolism through considerations of vascular distribution networks and biochemical kinetics. MTE has also been extended to characterise processes from cellular to global levels. MTE has generated both enthusiasm and controversy across a broad range of...

Altimeter-derived seasonal circulation on the southwest Atlantic shelf: 27°–43°S

Creator:: Strub, P. Ted, James, Corinne, Combes, Vincent, Matano, Ricardo P., Piola, Alberto R., Palma, Elbio D., Saraceno, Martin, Guerrero, Raul A., Fenco, Harold, and Ruiz-Etcheverry, Laura A.
Abstract:: Altimeter sea surface height (SSH) fields are analyzed to define and discuss the seasonal circulation over the wide continental shelf in the SW Atlantic Ocean (27°–43°S) during 2001–2012. Seasonal variability is low south of the Rio de la Plata (RdlP), where winds and currents remain equatorward for most of the...

Ecohydrological consequences of drought‐ and infestation‐triggered tree die‐off: insights and hypotheses

Creator:: Adams, Henry D., Luce, Charles H., Breshears, David D., Allen, Craig D., Weiler, Markus, Hale, V. Cody, Smith, Alistair M. S., and Huxman, Travis E.
Abstract:: Widespread, rapid, drought-, and infestation-triggered tree mortality is emerging as a phenomenon affecting forests globally and may be linked to increasing temperatures and drought frequency and severity. The ecohydrological consequences of forest die-off have been little studied and remain highly uncertain. To explore this knowledge gap, we apply the extensive...

Traits, properties, and performance: how woody plants combine hydraulic and mechanical functions in a cell, tissue, or whole plant

Creator:: Lachenbruch, Barbara and McCulloh, Katherine A.
Abstract:: This review presents a framework for evaluating how cells, tissues, organs, and whole plants perform both hydraulic and mechanical functions. The morphological alterations that affect dual functionality are varied: individual cells can have altered morphology; tissues can have altered partitioning to functions or altered cell alignment; and organs and whole...

Linking nonstructural carbohydrate dynamics to gas exchange and leaf hydraulic behavior in Pinus edulis and Juniperus monosperma

Creator:: Woodruff, David R., Meinzer, Frederick C., Marias, Danielle E., Sevanto, Sanna, Jenkins, Michael W., and McDowell, Nate G.
Abstract:: Leaf hydraulics, gas exchange and carbon storage in Pinus edulis and Juniperus monosperma, two tree species on opposite ends of the isohydry–anisohydry spectrum, were analyzed to examine relationships between hydraulic function and carbohydrate dynamics. Leaf hydraulic vulnerability, leaf water potential (Wl), leaf hydraulic conductance (Kleaf), photosynthesis (A), stomatal conductance (gs)...
