Dawson TE (1993) Water sources of plants as determined from
xylem-water isotopic composition: perspectives on plant
competition, distribution, and water relations. In Stable Isotopes
and Plant Carbon-Water Relations (Ehleringer JR, Hall AE, Farquhar
GD, eds). Academic Press, San Diego, CA, pp. 465-495.
Nice overview on tracking plant water using isotopes with plenty of
slick examples (though we’re saving the slickest for later).
Sternberg LdSL, Mulkey SS, Wright SJ (1989) Oxygen Isotope
ratio stratification in a tropical moist forest. Oecologia 81: 5156
Just like for carbon, oxygen isotopes vary up the canopy. Interesting
implications for giraffes and other canopy feeders.
Helliker BR, Richter SL (2008) Subtropical to boreal
convergence of tree-leaf temperatures. Nature 454: 511-514
Interesting paper that suggest tree leaves grow at the same
temperature across 50° of latitude (i.e., despite a huge change in
ambient temperature. Major implications for plant physiological
ecology and paleoclimatology.
