The blind men and the elephant: The impact of context and scale in evaluating conflicts between plant hydraulic safety and efficiency

Creator:: Meinzer, Frederick C., McCulloh, Katherine A., Lachenbruch, Barbara, Woodruff, David R., and Johnson, Daniel M.
Abstract:: Given the fundamental importance of xylem safety and efficiency for plant survival and fitness, it is not surprising that these are among the most commonly studied features of hydraulic architecture. However, much remains to be learned about the nature and universality of conflicts between hydraulic safety and efficiency. Although selection...

An Annual Pattern of Native Embolism in Upper Branches of Four Tall Conifer Species

Creator:: McCulloh, Katherine A., Johnson, Daniel M., Meinzer, Frederick C., and Lachenbruch, Barbara
Abstract:: Premise of the study: The Pacific Northwest of North America experiences relatively mild winters and dry summers. For the tall coniferous trees that grow in this region, we predicted that loss in the hydraulic conductivity of uppermost branches would be avoided because of difficulty reversing accumulated emboli in xylem that...

A comparison of daily water use estimates derived from constant-heat sap-flow probe values and gravimetric measurements in pot-grown saplings.

Creator:: McCulloh, Katherine A., Winter, Klaus, Meinzer, Frederick C., Garcia, Milton, Aranda, Jorge, and Lachenbruch, Barbara
Abstract:: Use of Granier-style heat dissipation sensors to measure sap flow is common in plant physiology, ecology and hydrology. There has been concern that any change to the original Granier design invalidates the empirical relationship between sap flux density and the temperature difference between the probes. Here, we compared daily water...

Impacts of tree height on leaf hydraulic architecture and stomatal control in Douglas-fir

Creator:: Woodruff, David R., McCulloh, Katherine A., Warren, Jeffrey M., Meinzer, Frederick C., and Lachenbruch, Barbara
Abstract:: This study investigated the mechanisms involved in the regulation of stomatal closure in Douglas-fir and evaluated the potential impact of compensatory adjustments in response to increasing tree height upon these mechanisms. In the laboratory, we measured leaf hydraulic conductance (Kleaf) as leaf water potential (Yl) declined for comparison with in...

Xylem hydraulic safety margins in woody plants: coordination of stomatal control of xylem tension with hydraulic capacitance

Creator:: Meinzer, Frederick C., Johnson, Daniel M., Lachenbruch, Barbara, McCulloh, Katherine A., and Woodruff, David R.
Abstract:: 1. The xylem pressure inducing 50% loss of hydraulic conductivity due to embolism widely used for comparisons of xylem vulnerability among species and across aridity However, despite its utility as an index of resistance to catastrophic xylem failure drought, P5o may have no special physiological relevance in the context of...

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,...

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. •...

Wood density and fiber length in young populus stems: relation to clone, age, growth rate, and pruning

Creator:: DeBell, Dean S., Singleton, Ryan, Harrington, Constance A., and Gartner, Barbara L.
Abstract:: Cross-sectional disks were cut at two stem heights (1.5 m and 3.0 m) from 9-year-old trees of three Populus clones grown in an intensively-cultured plantation in western Washington. At age 1.5 years, when the trees averaged 3.4 m tall, half of the trees were pruned by removing all branches below...

Climate-related trends in sapwood biophysical properties in two conifers: avoidance of hydraulic dysfunction through coordinated adjustments in xylem efficiency, safety, and capacitance.

Creator:: Barnard, David M., Meinzer, Frederick C., Lachenbruch, Barbara, McCulloh, Katherine A., Johnson, Daniel M., and Woodruff, David R.
Abstract:: In the Pacific north-west, the Cascade Mountain Range blocks much of the precipitation and maritime influence of the Pacific Ocean, resulting in distinct climates east and west of the mountains. The current study aimed to investigate relationships between water storage and transport properties in populations of Douglas-fir (Pseudotsuga menziesii) and...

Maximum height in a conifer is associated with conflicting requirements for xylem design

Creator:: Domec, Jean-Christophe, Lachenbruch, Barbara, Meinzer, Frederick C., Woodruff, David R., Warren, Jeffrey M., and McCulloh, Katherine A.
Abstract:: Despite renewed interest in the nature of limitations on maximum tree height, the mechanisms governing ultimate and species-specific height limits are not yet understood, but likely involve water transport dynamics. Tall trees experience increased risk of xylem embolism from air-seeding because tension in their water column increases with height due...
