Gas exchange and hydraulic properties in the crowns of two tree species in a Panamanian moist forest

  title={Gas exchange and hydraulic properties in the crowns of two tree species in a Panamanian moist forest},
  author={Nathan Phillips and Barbara J. Bond and Michael G. Ryan},
Abstract. Hydraulic properties and gas exchange were measured in branches of two tropical tree species (Simarouba amara Aubl. and Tapirira guianensis Aubl.) in a moist lowland forest in Panama. Branch-level sapflow, leaf-level stomatal conductance, and water potential measurements, along with measurements of specific hydraulic conductivity of stems in crown tops, were used to relate hydraulic parameters to leaf conductance in two individuals of each species. Branches of the taller trees for… 

Hydraulic characteristics and leaf water use efficiency in trees from tropical montane habitats

This study was carried out in pioneer and successional forest tree species in a lower montane tropical forest with seasonal rains. We tested whether pioneer species feature high hydraulic conductance

The hydraulic performance of tropical rainforest trees in their perhumid environment - is there evidence for drought vulnerability?

In a species-rich perhumid tropical rainforest of Central Sulawesi, Indonesia, we studied the hydraulic properties of eight representative tree species and searched for evidence that analyzing

Leaf area compounds height-related hydraulic costs of water transport in Oregon White Oak trees

The results provide further support and generality to the hypothesis of hydraulic limitations to tree-water flux, and show that limitations to water flux are not necessarily accompanied by the structural compensation of reduced crown leaf area in larger trees.

Hydraulic responses to height growth in maritime pine trees

As trees grow taller, decreased xylem path conductance imposes a major constraint on plant water and carbon balance, and is thus a key factor underlying forest productivity decline with age. The

A test of the hydraulic limitation hypothesis in fast‐growing Eucalyptus saligna

The hydraulic limitation hypothesis failed to explain the sharp decline in net primary productivity after canopy closure in this study, but the combination of similar G T and lower δ 13 C for the 26 m trees suggests that total crown photosynthesis was lower for the 27 m trees, perhaps a result of the lower Ψ LEAF.

Stomatal conductance, transpiration and sap flow of tropical montane rain forest trees in the southern Ecuadorian Andes.

An upper limit to transpiration in the investigated trees is indicated, even when soil water supply was not limiting, which indicates whole-plant water use was more pronounced among trees differing in size and crown status than among species.

Comparative hydraulic and anatomic properties in palm trees (Washingtonia robusta) of varying heights: implications for hydraulic limitation to increased height growth

Findings are consistent with hydraulic compensation in that tall palms may be overcoming the increased path length resistance through smaller, more efficient leaves and lower leaf water potentials than shorter palms.

Effects of hydraulic architecture and spatial variation in light on mean stomatal conductance of tree branches and crowns.

A porous medium model of water flow in trees produced a pattern of variation below the upper limit that was consistent with the observed variability in branch-estimated G(S).

The hydraulic limitation hypothesis revisited.

It is concluded that hydraulic limitation of gas exchange with increasing tree size is common, but not universal, and any limit to height or height growth does not appear to be related to the so-called age-related decline in wood production of forests after canopy closure.



Regulation of water flux through trunks, branches, and leaves in trees of a lowland tropical forest

It is suggested that reliance on measurements gathered at a single scale or inadequate range of scale may result in misleading conclusions concerning physiological differences in regulation of transpiration.

Evidence that hydraulic conductance limits photosynthesis in old Pinus ponderosa trees.

Leaf nitrogen content and photosynthetic capacity were similar suggesting that differences in g(s) and A between old and young trees were not caused by differences in photosynthesis capacity.

Limitation of transpiration by hydraulic conductance and xylem cavitation in Betula occidentalis

The extent to which stomatal conductance (gs) was capable of responding to reduced hydraulic conductance (k)and preventing cavitation-inducing xylem pressures was evaluated in the small riparian

Hydraulic Architecture of Woody Tropical Plants

This chapter reviews how hydraulic architectures of tropical trees and lianas (woody vines) influence the flow of water from roots to leaves. The hydraulic design potentially can limit plant water

Control of transpiration from the upper canopy of a tropical forest: the role of stomatal, boundary layer and hydraulic architecture components

Concurrent, independent measurements of stomatal conductance (gs), transpiration (E) and microenvironmental variables were used to characterize control of crown transpiration in four tree species

The Effect of Reduced Hydraulic Conductance on Stomatal Conductance and Xylem Cavitation

This work studied the ability of the stomata to prevent cavitation-inducing pressures when whole-plant hydraulic conductance per leaf area was reduced by making overlapping transverse cuts in the main stem.

Light environment, gas exchange, and annual growth of saplings of three species of rain forest trees in Costa Rica

Light environment, leaf physiological characteristics, and growth were compared for forest-grown saplings of three species of tropical trees with known life histories, and highest average rates were found for Simarouba amara, a fast-growing, light-demanding species.

Models of water flux through forest stands: critical leaf and stand parameters.

Models of canopy and aerodynamic conductance are available, but more mechanistic models of stomatal conductance, and further development of turbulence theory are needed along with improved estimates of leaf area index, leaf area distribution, and seasonal dynamics.
