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...

A comparison of the hydraulic efficiency of a palm species (Iriartea deltoidea) with other wood types

Creator:: Renninger, Heidi J., McCulloh, Katherine A., and Phillips, Nathan
Abstract:: Palms are an important component of tropical ecosystems, living alongside dicotyledonous trees, even though they have a very different growth pattern and vascular system. As monocots, vessels in palms are located within vascular bundles and, without a vascular cambium that many dicotyledonous trees possess, palms cannot add additional vessels to...

Expression of functional traits during seedling establishment in two populations of Pinus ponderosa from contrasting climates

Creator:: Kerr, Kelly L., Meinzer, Frederick C., McCulloh, Katherine A., Woodruff, David R., and Marias, Danielle E.
Abstract:: First-year tree seedlings represent a particularly vulnerable life stage and successful seedling establishment is crucial for forest regeneration. We investigated the extent to which Pinus ponderosa P. & C. Lawson populations from different climate zones exhibit differential expression of functional traits that may facilitate their establishment. Seeds from two populations...

Dynamics of leaf water relations components in co-occurring iso- and anisohydric conifer species

Creator:: Meinzer, Frederick C., Woodruff, David R., Marias, Danielle E., McCulloh, Katherine A., and Sevanto, Sanna
Abstract:: Because iso- and anisohydric species differ in stomatal regulation of the rate and magnitude of fluctuations in shoot water potential, they may be expected to show differences in the plasticity of their shoot water relations components, but explicit comparisons of this nature have rarely been made. We subjected excised shoots...

The dynamic pipeline: hydraulic capacitance and xylem hydraulic safety in four tall conifer species

Creator:: McCulloh, Katherine A., Johnson, Daniel M., Meinzer, Frederick C., and Woodruff, David R.
Abstract:: Recent work has suggested that plants differ in their relative reliance on structural avoidance of embolism versus maintenance of the xylem water column through dynamic traits such as capacitance, but we still know little about how and why species differ along this continuum. It is even less clear how or...

Contrasting Hydraulic Strategies in Two Tropical Lianas and Their Host Trees

Creator:: Johnson, Daniel M., Domec, Jean-Christophe, Woodruff, David R., McCulloh, Katherine A., and Meinzer, Frederick C.
Abstract:: • Premise of the Study: Tropical liana abundance has been increasing over the past 40 yr, which has been associated with reduced rainfall. The proposed mechanism allowing lianas to thrive in dry conditions is deeper root systems than co-occurring trees, although we know very little about the fundamental hydraulic physiology...

Do Ray Cells Provide a Pathway for Radial Water Movement in the Stems of Conifer Trees?

Creator:: Barnard, David M., Lachenbruch, Barbara, McCulloh, Katherine A., Kitin, Peter, and Meinzer, Frederick C.
Abstract:: • Premise of the study: The pathway of radial water movement in tree stems presents an unknown with respect to whole-tree hydraulics. Radial profi les have shown substantial axial sap fl ow in deeper layers of sapwood (that may lack direct connection to transpiring leaves), which suggests the existence of...

Hydraulic safety margins and embolism reversal in stems and leaves: Why are conifers and angiosperms so different?

Creator:: Johnson, Daniel M., McCulloh, Katherine A., Woodruff, David R., and Meinzer, Frederick C.
Abstract:: Angiosperm and coniferous tree species utilize a continuum of hydraulic strategies. Hydraulic safety margins (defined as differences between naturally occurring xylem pressures and pressures that would cause hydraulic dysfunction, or differences between pressures resulting in loss of hydraulic function in adjacent organs (e.g., stems vs. leaves) tend to be much...

Evidence for xylem embolism as a primary factor in dehydration-induced declines in leaf hydraulic conductance

Creator:: Johnson, Daniel M., McCulloh, Katherine A., Woodruff, David R., and Meinzer, Frederick C.
Abstract:: Hydraulic conductance of leaves (K[subscript leaf]) typically decreases with increasing water stress and recent studies have proposed different mechanisms responsible for decreasing K[subscript leaf]. We measured K[subscript leaf] concurrently with ultrasonic acoustic emissions (UAEs) in dehydrating leaves of several species to determine whether declining K[subscript leaf] was associated with xylem...
