Global forests are experiencing rising temperatures and more severe droughts, with
consistently dire forecasts for negative future impacts. Current research on the physiological …

In the stems of terrestrial vascular plants studied to date, the diameter of xylem water‐
conducting conduits D widens predictably with distance from the stem tip L approximating …

Understanding how plants survive drought and cold is increasingly important as plants
worldwide experience dieback with drought in moist places and grow taller with warming in …

Tropical tree height-diameter (H: D) relationships may vary by forest type and region making
large-scale estimates of above-ground biomass subject to bias if they ignore these …

Summary 1 Understanding the factors influencing tree growth is central to forest ecology
because of the significance of growth to forest structure and biomass. One of the simplest …

Summary 1 Tree‐size distributions are changing in many natural forests around the world,
and it is important to understand the underlying processes that are causing these changes …

Abstract Purpose of Review This review shows that a more or less constant rate of tip-to-
base vessel widening across species, together with the assumption that wider vessels are …

Within a tree the lumen of the xylem conduits varies widely (by at least 1 order of
magnitude). Transversally in the stem conduits are smaller close to the pith and larger in the …

Variation in angiosperm vessel diameter is of major functional significance. In the light of
recent models predicting optimal vessel taper given resistance imposed by conductive path …

Shaping global water and carbon cycles, plants lift water from roots to leaves through xylem
conduits. The importance of xylem water conduction makes it crucial to understand how …
