heat dissipation sensors of variable length for the measurement of sap flow in trees with deep sapwood.	robust thermal dissipation sensors of variable length (3 to 30 cm) were developed to overcome limitations to the measurement of radial profiles of sap flow in large-diameter tropical trees with deep sapwood. the effective measuring length of the custom-made sensors was reduced to 1 cm at the tip of a thermally nonconducting shaft, thereby minimizing the influence of nonuniform sap flux density profiles across the sapwood. sap flow was measured at different depths and circumferential positions in ...	2002	11874724
transpiration efficiency of a tropical pioneer tree (ficus insipida) in relation to soil fertility.	the response of whole-plant water-use efficiency, termed transpiration efficiency (te), to variation in soil fertility was assessed in a tropical pioneer tree, ficus insipida willd. measurements of stable isotope ratios (delta(13)c, delta(18)o, delta(15)n), elemental concentrations (c, n, p), plant growth, instantaneous leaf gas exchange, and whole-plant water use were used to analyse the mechanisms controlling te. plants were grown individually in 19 l pots with non-limiting soil moisture. soil ...	2007	18057036
