• An hydraulic model of a tree stem is presented to help understand how the carbon storage in ecosystems varies with changing environmental conditions. • The model is based on the assumption that a tree stem is a collection of parallel pipes and was used to (qualitatively) predict how the mass concentration of dry matter ([D]) would vary with water temperature (via changes in viscosity), nitrogen supply and atmospheric CO2 . • There was qualitative agreement between model predictions and…

A demonstration of the theoretical prediction that sap velocity is related to wood density in the conifer Dacrydium cupressinum.

•  The theoretical prediction of a close relationship between sap velocity (v) and wood density (ρb ) in conifers was tested in mature Dacrydium cupressinum trees. •  Thermal dissipation probes were

Measuring sap flow and stem water content in trees: a critical analysis and development of a new heat pulse method (Sapflow+)

Just as carbon, water is indispensable for plants to develop and grow. A lack of water causes turgor loss in plant cells which prevents further expansion of these cells and the coupled incorporation

New type of vulnerability curve gives insight in the hydraulic capacitance and conductivity of the xylem

Drought vulnerability of trees and other woody plants is much debated in the context of climate change, which creates a high interest in understanding plant water relations. The role and functioning

Changes in petiole hydraulic properties and leaf water flow in birch and oak saplings in a CO2-enriched atmosphere.

Elevated [CO(2)] consistently decreased water flow and total vessel area of the petiole in sun leaves and had no effect on these parameters in shade leaves, perhaps because g(s) of shade leaves was already low.

Angiosperm wood structure: Global patterns in vessel anatomy and their relation to wood density and potential conductivity.

Improved theory and quantification are needed to better understand ecological costs and benefits of these three distinct dimensions, including hydraulic conductivity, capacitance, and construction costs.

Temperature effects on wood anatomy, wood density, photosynthesis and biomass partitioning of Eucalyptus grandis seedlings.

Increased wood density was also related to a shift in partitioning of seedling biomass from roots to stems as temperature increased, and changes in cell wall characteristics could be considered analogous to changes in carbon supply.

Predictable changes in aboveground allometry of trees along gradients of temperature, aridity and competition

This work quantifies how environmental conditions influence the scaling of height and crown diameter (CD) with stem diameter (d.b.h.–CD) and highlights the role of hydraulic limitations in this region of Spain, where climate varies strongly.

The hydraulic architecture of trees and other woody plants

summary In this paper, we have reviewed how the hydraulic design of trees influences the movement of water from roots to leaves. The hydraulic architecture of trees can limit their water relations,

Wood is formed in an essentially water-saturated environment in the living tree, and the cell wall remains in this state until the water flow from the roots is interrupted, such as by felling the

Tree ring responses to elevated CO2 and increased N deposition in Picea abies

Four- to seven-year-old spruce trees (Picea abies) were exposed to three CO2 concentrations (280, 420 and 560 cm3 m−3) and three rates of wet N deposition (0, 30 and 90 kg ha−1 year−1) for 3 years in

It is concluded that measures of mass and density will be necessary before plant growth analysis can achieve its full potential and be shown to be very difficult to interpret.

An increase in growth efficiency implies a potential increase in carbon sequestration by forests, subject to critical assumptions about forest canopy development in a CO2 -enriched atmosphere.

The competitive ability of the extreme pioneer species, Prunus pensylvanica (pin cherry), was expected to be enhanced by increased nutrient supply, with consequent effects at the community and ecosystem levels of organization.
