Clayton, Dale H. | Common grackle anting with lime fruit and its effect on ectoparasites | Anting is stereotyped behavior in which birds ex- pose themselves to fluid-secreting ants or other pun- gent substances. During "active" anting a bird crush- es an ant in the bill and rubs it frenetically through its plumage (Rothschild and Clay 1952). During "passive" anting a bird entices ants to ... | Quiscalus quiscala; Columbicola columbae; Anting; Ectoparasites | 1993 |

Goller, Franz | Superfast vocal muscles control song production in songbirds | Birdsong is a widely used model for vocal learning and human speech, which exhibits high temporal and acoustic diversity. Rapid acoustic modulations are thought to arise from the vocal organ, the syrinx, by passive interactions between the two independent sound generators or intrinsic nonlinear dyna... | Vocal muscles; Syringeal muscles; Sturnus vulgaris | 2008 |

Goller, Franz | Nonlinear model predicts diverse respiratory patterns of birdsong | A central aspect of the motor control of birdsong production is the capacity to generate diverse respiratory rhythms, which determine the coarse temporal pattern of song. The neural mechanisms that underlie this diversity of respiratory gestures and the resulting acoustic syllables are largely unkn... | Sound; Syllables; Song | 2006 |

Sekercioglu, Cagan | The need to quantify ecosystem services provided by birds | What are birds worth-what is their actual dollar value to human society? To most of us in the ornithological community, birds are invaluable. But in these times we need more specific rationales to convince policy makers and business leaders to include bird conservation in land-use and development de... | 2011-01-01 | |

Blair, David F. | Electron spin relaxation of CuA and cytochrome a in cytochrome c oxidase: comparison to heme, copper, and sulfur radical complexes | The method of continuous saturation has been used to measure the electron spin relaxation parameter T1T2 at temperatures between 10 and 50 K for a variety of S = % species including: CuA and cytochrome a of cytochrome c oxidase, the type1 copper in several blue copper proteins, the type 2 coppe... | Electron spin relaxation; EPR signals; Sulfur radical complexes | 1984 |

Olivera, Baldomero M. | Identification of Conus peptidylprolyl cis-trans isomerases (PPIases) and assessment of their role in the oxidative folding of conotoxins | Peptidylprolyl cis-trans isomerases (PPIases) are ubiquitous proteins that catalyze the cis-trans isomerization of prolines. A number of proteins, such as Drosophila rhodopsin and the human immunodeficiency viral protein HIV-1 Gag, have been identified as endogenous substrates for PPIases. However, ... | 2010 | |

Goller, Franz | Prosthetic Avian vocal organ controlled by a freely behaving bird based on a low dimensional model of the biomechanical periphery | Because of the parallels found with human language production and acquisition, birdsong is an ideal animal model to study general mechanisms underlying complex, learned motor behavior. The rich and diverse vocalizations of songbirds emerge as a result of the interaction between a pattern generator i... | 2012-01-01 | |

Olivera, Baldomero M. | Modulation of conotoxin structure and function is achieved through a multienzyme complex in the venom glands of cone snails | Background: Conotoxins can be utilized to investigate enzyme-assisted folding of disulfide-rich peptides. Results: Various ER-resident cone snail enzymes act in concert to accelerate the oxidative folding of conotoxins and modulate their conformation by reconfiguring disulfide connectivities. Conclu... | 2012-01-01 | |

Ehleringer, James R.; Negus, Norman C. | Red Butte Canyon Research Natural Area: history, flora, geology, climate, and ecology | Red Butte Canyon is a protected, near pristine canyon entering Salt Lake Valley, Utah. It contains a well-developed riparian zone and a perennial stream; hillside vegetation ranges from grasslands on the lower limits to Douglas-fir and aspen stands at the upper elevations. In this paper we describe ... | Intermountain West; Grassland; Oak-maple; Plant adaptation; Red Butte Canyon Research Natural Area; Human impact | 1992 |
