Coley, Phyllis D. | Rates of herbivory on different tropical trees | Rates of herbivory on marked young and mature leaves from saplings of 21 canopy tree species were measured in the wet and dry seasons. Species were classified into two life history groups: persistent species which are found throughout the shaded understory, and pioneer species which only become e... | Herbivory; Grazing damage; Tropical trees; Pioneer species; Trees -- Tropics | 1982 |

Adler, Frederick R.; Liou, Theodore G. | Use of lung transplantation survival models to refine patient selection in cystic fibrosis | Lung transplantation in cystic fibrosis may improve survival for patients with low 5-year predicted survival. Identifying characteristics that affect post-transplantation survival may improve patient selection and survival benefit.

Ehleringer, James R. | Tracing changes in ecosystem function under elevated carbon dioxide conditions | Responses of ecosystems to elevated levels of atmospheric carbon dioxide (CO2) remain a critical uncertainty in global change research. Two key unknown factors are the fate of carbon newly incorporated by photosynthesis into various pools within the ecosystem and the extent to which elevated CO2 is... | Elevated carbon dioxide; Stable isotopes; Radiocarbon; Global change; Terrestrial ecosystems | 2003 |

Mattis, Daniel C. | Extinction of antiferromagnetism by holes in CuO2 | The introduction of a sufficient number of holes into antiferromagnetic planes of Cu02 in La-Cu-O and Y-Ba-Cu-O causes antiferromagnetism to disappear at a critical density xc, beyond which superconductivity occurs. We investigate two competing tendencies, which determine the dependence of xc on the... | Antiferromagnets | 1991-08 |

Morse, Michael David | The ground state and excited ?-hole states of CuAu | Resonant two-photon ionization spectroscopy has been applied to jet-cooled diatomic CuAu. Eight band systems have been observed, rotationally resolved, and analyzed. The ground state is X??+ in symmetry, deriving from the 3d??Cu 5d??Au, ?? molecular configuration. Its bond length has been determined... | | 1991 |

Miller, Joel Steven | Zero field splitting, field-dependent magnetization of mixed-valent S = 3/2 Diruthenium(II,III) tetracarboxylates | The 2 K field-dependent magnetization, M(H), of S = 3/2 [RunII/III2(OAc)4]+ was studied. [RuII/III 2(OAc)4]+ exhibits an unusually low magnetization with respect to that predicted by the classical Brillouin function. This reduced value is a consequence of the large anisotropy arising from the large ... | Spin; Coupling; Expressions | 2004 |

Ehleringer, James R. | ENSO effects on primary productivity in Southern Atacama desert | In the winter-rain southern Atacama Desert of the Coquimbo Region of Chile, El Niño - Southern Oscillation (ENSO) events modulate primary productivity. In this region, there are important changes in water availability between La Niña (dry) and El Niño (rainy) years.

Farmer, Colleen G. | Right-to-left shunt of crocodilians serves digestion | All amniotes except birds and mammals have the ability to shunt blood past the lungs, hut the physiological function of this ability is poorly understood. We studied the role of the shunt in digestion in juvenile American alligators in the following ways. First, we characterized the shunt in fasting... | Postprandial; Alligators; Gastrointestinal | 2008 |

DeTar, Carleton | Potts flux tube model at nonzero chemical potential | We model the deconfinement phase transition in quantum chromodynamics at nonzero baryon number density and large quark mass by extending the flux tube model ~three-state, three-dimensional Potts model! to nonzero chemical potential.

Carrier, David R. | Evidence for endothermic ancestors of crocodiles at the stem of archosaur evolution | Physiological, anatomical, and developmental features of the crocodilian heart support the paleontological evidence that the ancestors of living crocodilians were active and endothermic, but the lineage reverted to ectothermy when it invaded the aquatic, ambush predator niche. In endotherms, there i... | Endothermy; ectothermy; Archosaur evolution; Archosaurs; Crocodilian heart | 2004 |

Crespo, Jose Guillermo | Olfactory modulation of pre-flight shivering behavior in male moths | In nocturnal moths olfaction is the predominant sensory modality shaping many of the adult animal?s activities, including reproduction. A two-component pheromone blend is sufficient to elicit the typical zigzag upwind flight behavior in Helicoverpa zea males. However, before flight can be initiated,... | thermoregulation, warm-up, flight, sex pheromone, Noctuidae, insect Department: Biology | 2011-01-02 |

Goller, Franz | Motor control of crystallized song is modified by sensory feedback | Song production requires precisely coordinated activity in the respiratory and syringcal (vocal organ) muscles. Crystallized adult song is characterized by acoustic and motor stereotypy which does not require auditory feedback, suggesting it is represented by fixed central motor programs. To determ... | Air injection; Auditory feedback; Pressure | 1997 |
