 | Ehleringer, James R. | Oxygen isotope ratios of waters and respired CO2 in Amazonian forest and pasture ecosystems | The oxygen isotope ratio (d18O, SMOW) of atmospheric CO2 is a powerful indicator of large-scale CO2 exchange on land. Oxygen isotopic exchange between CO2 and water in leaves and soils controls the d18O of atmospheric CO2. Currently there is little empirical information on the spatial and temporal ... | Amazonia; Carbon dioxide (CO2); Oxygen isotope ratio; Photosynthesis; Respiration; Stable isotope ratio; Tropical forests | 2005 |

 | Coley, Phyllis D.; Kursar, Thomas A. | Pests vs. drought as determinants of plant distribution along a tropical rainfall gradient | Understanding the mechanisms that shape the distribution of organisms can help explain patterns of local and regional biodiversity and predict the susceptibility of communities to environmental change. In the species-rich tropics, a gradient in rainfall between wet evergreen and dry seasonal forests... | Drought tolerance; Herbivory; Panama; Pathogen attack; Rainfall gradient; Tree distribution; Tropical forests | 2009 |
