This doesn't hold in our example, at least for P. hothamensis The trait shift toward higher Narea in species occurring at lower rainfall constitutes a shift upward in terms of the two-input framework in figure 2a. Of the possible upward shifts, alternatives C and E were those mainly observed. The average shift between species in the Australian lownutrient rainfall contrast can be characterized as a shift from H1 to C; on average, low-rainfall species had higher Narea, lower gs, and similar Aarea to high-rainfall species (fig. 3b, 3e; fig. 4b). Photosynthetic nitrogen-use efficiency was lower for species operating at low humidity, but theirWUE was similar (the shift toward lower gs counterbalanced the difference in ambient water vapor pressure). By contrast, the average shift between species in the Australian highnutrient and U.S. contrasts consisted of higher Aarea and Narea but similar gs in low-rainfall species (shift from H1 to E). However, since Aarea increased proportionally less than Narea and estimated transpiration, both PNUE and WUE were on average lower for the low-rainfall species in these data sets (E in fig. 2d). Drier sites had lower PNUE and the increase in Nla wasn't a result of differences n SLA similar equal-cost slopes in the high- and low-humidity habitats. In summary, the average type of strategy shift observed in two of the three sets of contrasts did not connote a change in the relative cost of water versus nitrogen at low rainfall, whereas in one contrast it did: water appeared to be relatively more expensive than nitrogen at low rainfall. see DeLucia and Schlesinger 1991}, interhash = {01af7383df50c39c5f34cb1c94642a2f}, intrahash = {d84bded594c6f225befc27fcd733f556}, journal = {The American Naturalist}, keywords = {bibtex-import, citeulikeExport gas\_exchange, nitrogen, unread}, pages = {98--111}, posted-at = {2007-07-31 07:40:19}, priority = {2}, timestamp = {2019-03-31T01:16:26.000+0100}, title = {{Least-Cost Input Mixtures of Water and Nitrogen for Photosynthesis}}, volume = 161, year = 2003 }
