Coley, Phyllis D. | Between-species differences in leaf defenses of tropical trees | Rates of herbivory and patterns of leaf defense are presented for light-demanding and shade-tolerant tree species growing in a lowland rainforest in Panama. More than 85 percent of the annual leaf damage is due to grazing by insects. There are over three orders of magnitude difference between specie... | Herbivory; Interspecific variation; Panama; Growth rate; Shade tolerance; Treefall gaps; Tropical forest; Understory; Tannins; Alkaloids | 1987 |

Ehleringer, James R. | Carbon isotope ratios of Atacama Desert plants reflect hyperaridity of region in northern Chile | Leaf carbon isotope ratios were measured on plants from the coastal portions of the Atacama Desert at Pan de Azucar and Paposo, Chile. Most species possessed C3 photosynthesis, although there were several CAM species, indications of some facultative CAM species, and only one C4 species. The carbon i... | Atacama Desert; Carbon isotope ratio; Intercellular carbon dioxide concentration; Hyperaridity | 1998 |

Ehleringer, James R. | Fuentes de aqua utilizadas por las plantas desérticas y su importancia en planes de manejo y restauración ecológica | El agua es el factor más importante que afecta a la productividad primaria y la estructura de la vegetación en ecosistemas áridos. Dado que las especies de plantas pueden diferir en sus capacidades de utilizar distintas fuentes de agua, el conocimiento de estos aspectos es fundamental para los ... | Fuentes de agua; Isótopos estables; 8-H; 5 l sO; Zonas áridas; Plantas desérticas; Relaciones hídricas; Restauración ecológica; Desierto de Atacama; Atacama Desert; Stable isotopes; Water sources; Arid regions; Ecological restoration; Water relations; Water supplies | 2000 |

Ehleringer, James R. | Grupos funcionales en arbustos deserticos del norte de Chile, definidos sobre la base de las fuentes de agua utilizadas | La productividad primaria y la estructura de la vegetación en ecosistemas áridos están determinadas por la disponibilidad de agua. En un estudio realizado en el secano costero del norte-centro de Chile (29/43'S; 71/14'O, 300 m) se compararon los mecanismos de utilización de distintas fuentes de... | Grupos funcionales; Functional groups; Arbustos deserticos; Desert shrubs; Fuentes de agua; Water sources; Water availability; Arid ecosystems; Pastoreo con caprinos; Goat overgrazing | 1999-01-01 |

Bohs, Lynn A. | Ethnobotany of the genus Cyphomandra (Solanaceae) | Plants of the genus Cyphomandra (Solanaceae) have long been utilized for their edible fruits in their native Latin America. The best-known species is the domesticated tree tomato or tamarillo, Cyphomandra betacea. This species, popular as a raw or cooked fruit, is widely cultivated in Andean South ... | Cyphomandra; Cyphomandra betacea; Alkaloids | 1989 |

Carrier, David R. | Functional tradeoffs in specialization for fighting versus running | Both locomotion and fighting are critical to survival and reproductive fitness in many vertebrate species. Yet, characters that make an individual good at fighting may, in many cases, limit locomotor performance and vice versa. Here I describe tests of three functional tradeoffs in the limb muscles ... | Greyhounds; Pit Bulls; Australopithecus; Homo; Fighting; Running; Male-male aggression; Limb muscles; Functional tradeoff | 2002 |

Potts, Wayne K. | Evolution of mating preferences and major histocompatibility complex genes | House mice prefer mates genetically dissimilar at the major histocompatibility complex (MHC). The highly polymorphic MHC genes control immunological self/nonself recognition; therefore, this mating preference may function to provide "good genes" for an individual's offspring. However, the evidence ... | Inbreeding; Parasites; Recognition | 1999 |
