Ecolog:
I have not kept up to date in this area, but I hope someone will be kind
enough to help me facilitate the necessary work to rectify that, beginning
with answers to the following question:
1. Has anyone studied the ratio of total water intake to biomass exclusive
of water content? (For example, a cactus and a "corn" plant? I would be most
interested to see graphic comparisons of a diverse and large number of
species. I am curious about the range of differences and the research
methodology.)

PS: I have left the message below attached for reference; it stimulated the
question, but there is no direct relationship.

Postdoctoral Position in Ecohydrology – Plant Water Use
The Biology Department and Nicholas School of the Environment at Duke
University seek a biological or earth system scientist in ecohydrology
and plant water transport. The three-year project, funded by the
National Science Foundation, compares the functioning of deep (5-20
meters underground) and shallow roots and stems for trees growing in the
southern United States. It uses a novel cave system developed by the PIs
in central Texas to study tree roots in situ and is based on previous
molecular-based fingerprinting to match the roots to their respective
shallow counterparts and tree trunks. The research questions include, 1)
How much water that trees use comes from deep underground? 2) What are
the unique physical characteristics of deep roots that promote water
transport? and 3) To what extent do specialized water channels in plants
contribute to their ability to take up and transport water? Primary
responsibilities may include installation and maintenance of sapflow and
microclimate monitoring equipment, periodic collection of plant
physiological and structural data, lab physiological and hydraulic
measurements, and/or modeling of water uptake and transport.
