Ehleringer, James R. | Implications of CO2 pooling on δ13C of ecosystem respiration and leaves in Amazonian forest | The carbon isotope of a leaf (δ13Cleaf) is generally more negative in riparian zones than in areas with low soil moisture content or rainfall input. In Central Amazonia, the small-scale topography is composed of plateaus and valleys, with plateaus generally having a lower soil moisture status ... | Amazonia; Carbon dioxide; Oxygen isotope ratio; Respiration; Soil water content | 2008 |

Goller, Franz | Lateralization as a symmetry breaking process in birdsong | The singing by songbirds is a most convincing example in the animal kingdom of functional lateralization of the brain, a feature usually associated with human language. Lateralization is expressed as one or both of the bird's sound sources being active during the vocalization. Normal songs require ... | Lateralization; Syringeal muscles; Respiration; Gating | 2007-03 |

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 |
