The evolution and functional significance of leaf shape in the angiosperms.
Angiosperm leaves manifest a remarkable diversity of shapes that range from developmental sequences within a shoot and within crown response to microenvironment to variation among species within andExpand

Wood anatomy and wood density in shrubs: Responses to varying aridity along transcontinental transects.
Wood density plays a key role in ecological strategies and life history variation in woody plants, but little is known about its anatomical basis in shrubs. We quantified the relationships betweenExpand

Hydraulic integration and shrub growth form linked across continental aridity gradients
Both engineered hydraulic systems and plant hydraulic systems are protected against failure by resistance, reparability, and redundancy. A basic rule of reliability engineering is that the level ofExpand

Most previous studies of evolutionary modification of form in plants have focused primarily on individual organs or flowers. Few have investigated the role of evolutionary changes in timing orExpand

Integration of vessel traits, wood density, and height in angiosperm shrubs and trees.
PREMISE OF THE STUDY Trees and shrubs tend to occupy different niches within and across ecosystems; therefore, traits related to their resource use and life history are expected to differ. Here weExpand

LEAF SHAPE EVOLUTION IN THE SOUTH AFRICAN GENUS PELARGONIUM L' HER. (GERANIACEAE)
Leaf shapes reflect complex assemblages of shape-determining elements, yet evolutionary studies tend to treat leaf shape as a single attribute, for example cordate or linear. As with all complexExpand

Phylogenetic influences on leaf trait integration in Pelargonium (Geraniaceae): convergence, divergence, and historical adaptation to a rapidly changing climate.
PREMISE OF THE STUDY Trait integration may improve prediction of species and lineage responses to future climate change more than individual traits alone, particularly when analyses incorporateExpand

The Effect of Axis Splitting on Xylem Pressure Potentials and Water Movement in the Desert Shrub Ambrosia dumosa (Gray) Payne (Asteraceae)
Predawn xylem pressure potential (XPP) measurements were used to investigate the effects of axis splitting on water relations of the Mojave Desert shrub Ambrosia dumosa. Differences among branchesExpand

Animal and forage responses on rotationally grazed Floralta limpograss and Pensacola bahiagrass pastures
The objective was to compare animal performance on limpograss and bahiagrass when they were rotationally grazed to 20- to 25-cm and 6- to 8-cm stubble heights, respectively, and fertilized with NExpand
