Stem flow and porometer measurements of transpiration from honey mesquite (Prosopis glandulosa)
The objective of this study was to compare stem flow and porometer methods of measuring transpiration of honey mesquite (Prosopis glandulosa) trees on a semiarid site. Stem flow was measured using heat balance stem flow gauges. Porometer measurements of leaf stomatal conductance (gs) were made within foliage layers of each stem and scaled to transpiration values for the entire stem (Estern) usi...
متن کاملTesting transpiration controls by quantifying spatial variability along a boreal black spruce forest drainage gradient
One of the biggest challenges in predicting ecohydrologic fluxes is scaling from easily measured variables to more difficult, often emergent patterns and processes. This is especially true in spatially heterogeneous systems such as black spruce (Picea mariana)dominated boreal forests containing excessive and low soil moisture conditions. Traditional hypotheses suggest that transpiration is cont...
متن کاملSeedling Growth of Two Honey Mesquite Varieties Under CO2 Enrichment
Seedlings of 2 varieties of honey mesquite (Prosopis glandulosa var. glandulosa and P. glandulosa var. torreyana) were exposed to 2 concentrations of atmospheric carbon dioxide (CO2) (368 and 704 lmol mol ) in environmentally controlled glasshouses under near-optimal temperature and soil water conditions to determine if CO2 enrichment alters aboveand belowground growth responses. CO2 enrichment...
متن کاملVariability in soil heat flux from a mesquite dune site
For many natural and agricultural landscapes, vegetation partially covers the ground surface, resulting in significant variations in soil heat flux between interspace areas and underneath vegetation. This is particularly apparent in arid and semiarid regions where vegetation cover is low and clustered or ‘clumped’ with large areas of exposed soil. Surface heterogeneity presents significant chal...
