Olivera, Baldomero M. | Novel venom peptides from the cone snail Conus pulicarius discovered through next-generation sequencing of its venom duct transcriptome | The venom peptides (i.e., conotoxins or conopeptides) that species in the genus Conus collectively produce are remarkably diverse, estimated to be around 50,000 to 140,000, but the pace of discovery and characterization of these peptides have been rather slow. To date, only a minor fraction have be... | | 2012 |

Sekercioglu, Cagan | Measuring the meltdown: drivers of global amphibian extinction and decline | Habitat loss, climate change, over-exploitation, disease and other factors have been hypothesised in the global decline of amphibian biodiversity. However, the relative importance of and synergies among different drivers are still poorly understood. We present the largest global analysis of roughly ... | | 2008-01-01 |

Olivera, Baldomero M. | Combined proteomic and transcriptomic interrogation of the venom gland of conus geographus uncovers novel components and functional compartmentalization | Cone snails are highly successful marine predators that use complex venoms to capture prey. At any given time, hundreds of toxins (conotoxins) are synthesized in the secretory epithelial cells of the venom gland, a long and convoluted organ that can measure 4 times the length of the snail's body. In... | | 2014-01-01 |

Sekercioglu, Cagan | Causes and consequences of bird extinctions | Increased human domination of the planet has caused the declines and extinctions of countless species. Each species has not only intrinsic value, but ecological functions of organisms are also essential for the integrity of ecosystems that allow people to benefit from essential free ecosystem servic... | | 2003-01-01 |

Potts, Wayne K.; Granger, Donald Lee | Major histocompatibility complex-dependent susceptibility to Cryptococcus neoformans in mice | To evaluate the role of major histocompatibility complex (MHC) genes in the resistance to Cryptococcus neoformans, we conducted infection experiments in MHC-congenic strains of mice. Significant MHC-dependent susceptibility differences were found among homozygotes and heterozygotes. This study is th... | MHC-congenic; Host resistance; Infection | 2003 |

Ehleringer, James R. | Carbon isotope ratios in belowground carbon cycle processes | Analyses of carbon isotope ratios (δ13C) in soil organic matter (SOM) and soil respired CO2 provide insights into dynamics of the carbon cycle. δ13C analyses do not provide direct measures of soil CO2 efflux rates but are useful as a constraint in carbon cycle models. In many cases, δ13C analyses... | Below ground processes; Ecosystems; Carbon cycle; Carbon isotope ratio; Ecosystem processes; Global change; Soil organic carbon; Soil organic matter | 2000 |

Coley, Phyllis D.; Kursar, Thomas A. | Food quality, competition, and parasitism influence feeding preference in a neotropical lepidopteran | We surveyed Lepidoptera found on 11 species of Inga (Fabaceae:Mimosoideae) co-existing on Barro Colorado Island, Panama, to evaluate factors influencing diet choice. Of the 47 species of caterpillars (747 individuals) recorded, each fed on a distinct set of Inga. In the field, 96% of the individuals... | Competition; Electivity; Gelechiid; Herbivore growth; Fabaceae; Inga; Leaf expansion; Leafing phenology; Lipidoptera; Panama; Parasitism; Plant quality | 2006 |

Sekercioglu, Cagan | Keystone species in seed dispersal networks are mainly determined by dietary specialization | One central issue in Ecology ecology has been the definition and identification of keystone species, i.e., species that are relatively more important than others for maintaining the structure of a community. Several keystone species concepts have been proposed, and network theory has been pointed o... | | 2014-01-01 |

Adler, Frederick R. | How virulent should a parasite be to its vector? | Vector-borne parasites are commonly predicted to be less virulent to the vector than to the definitive host as the parasite gains little by harming its main route of transmission. Here we assess the empirical evidence from systems in which insects are vectors for vertebrate, plant, and invertebrate ... | Parasite virulence; Hosts; Vector-borne parasite | 2003 |

Sekercioglu, Cagan | Landscape constraints on functional diversity of birds and insects in tropical agroecosystems | In this paper, we analyze databases on bird and insects to assess patterns of functional diversity in human-dominated landscapes in the tropics. Perspective from developed landscapes is essential for understanding remnant natural ecosystems, because most species experience their surroundings at spat... | | 2008-01-01 |

Thomas, Kirk R.; Capecchi, Mario R. | Maintenance of functional equivalence during paralogous Hox gene evolution. | Biological diversity is driven mainly by gene duplication followed by mutation and selection. This divergence in either regulatory or protein-coding sequences can result in quite different biological functions for even closely related genes. This concept is exemplified by the mammalian Hox gene comp... | Alleles; Animals; Cervical Vertebrae; Embryo; Genetic Complementation Test; Homeodomain Proteins; Homozygote; Mice | 2000-02-10 |

Coley, Phyllis D. | On turning green into gold | Anthropogenic effects on the climate and biodiversity of our planet are among the most troubling and perhaps irreversible threats facing scientists, policymakers, and citizens.

Sekercioglu, Cagan | Mapping functional traits: comparing bundance and presence-absence estimates at large spatial scales | Efforts to quantify the composition of biological communities increasingly focus on functional traits. The composition of communities in terms of traits can be summarized in several ways. Ecologists are beginning to map the geographic distribution of trait-based metrics from various sources of data,... | | 2012-01-01 |

Potts, Wayne K. | Infection-dependent phenotypes in MHC-congenic mice are not due to MHC: can we trust congenic animals? | Congenic strains of mice are assumed to differ only at a single gene or region of the genome. These mice have great importance in evaluating the function of genes. However, their utility depends on the maintenance of this true congenic nature. Although, accumulating evidence suggests that congenic ... | Strains; Mutations; Pathogen | 2004 |

Ehleringer, James R. | Patterns of local and nonlocal water resource use across the western U.S. determined via stable isotope intercomparisons | In the western U.S., the mismatch between public water demands and natural water availability necessitates large interbasin transfers of water as well as groundwater mining of fossil aquifers. Here we identify probable situations of nonlocal water use in both space and time based on isotopic compari... | | 2014-01-01 |

Coley, Phyllis D. | Tritrophic interactions in tropical versus temperate communities | The latitudinal gradient in diversity is one of the oldest (e.g., Wallace, 1878) and most obvious trends in ecology, and a wealth of literature is devoted to understanding both the causes and consequences of this gradient (Dobzhansky, 1950; also reviewed by Rohde, 1992).
