401 Olivera, Baldomero M.; Gray, William RobertNew family of Conus peptides targeted to the nicotinic acetylcholine receptorIn this work, a new family of Conus peptides, the αA-conotoxins, which target the nicotinic acetylcholine receptor, is defined. The first members of this family have been characterized from the eastern Pacific species, Conus purpurascens (the purple cone); three peptides that cause paralysis in fis...Conotoxins; Conus peptides; Conus purpurascens; Purple cone snail1995

403 Cieri, RobertNew insight into the evolution of the vertebrate respiratory system and the discovery of unidirectional airflow in iguana lungsThe generally accepted framework for the evolution of a key feature of the avian respiratory system, unidirectional airflow, is that it is an adaptation for efficiency of gas exchange and expanded aerobic capacities, and therefore it has historically been viewed as important to the ability of birds ...2014-11-17
404 Farmer, Colleen G.New perspective on the origin of endothermyA new hypothesis for the origin of endothermy in birds is discussed. I suggest extensive parental care provided the initial impetus for the evolution of endothermy. Among extant animals one of the most important functions of an endothermic metabolism is the incubation of embryos. Furthermore, I prop...Endothermy; Parental care; Thermogenesis; Reproduction; Hormone; Aerobic capacity2001
405 Bohs, Lynn A.New species of Solanum and Capsicum (Solanaceae) from Bolivia, with clarification of nomenclature in some Bolivian SolanumBolivian floristic diversity is high, reflecting its great topographic and habitat diversity. Habitats in Bolivia range from seasonally flooded savannas to arid Chaco and high elevation deserts to hyper-humid montane and lowland rainforests.Capsicum; Solanum; Bolivia; Biodiversity2006
406 Bohs, Lynn A.New species of Solanum section Cyphomandropsis (Solanaceae) from BoliviaA new species of Solanum sect.

Its strongly discolorous leaves densely covered below with white dendritic hairs distinguish it from the other species in the section.Solanum hibernum; Cyphomandropsis1994
407 Olivera, Baldomero M.; Gray, William Robert; McIntosh, J. MichaelNew α-conotoxin which targets α3ß2 nicotinic acetylcholine receptorsWe have isolated a 16-amino acid peptide from the venom of the marine snail Conus magus which potently blocks nicotinic acetylcholine receptors (nAChRs) composed of α3ß2 subunits.

410 Clayton, Dale H.Nocturnal foraging of yellow-crowned night herons in the BahamasDetailed observations of nocturnal foraging of the Yellow-crowned Night Heron (Nycticorax violacevs) are not to be found in the literature, though this species commonly feeds at night (Kushlan 1978, Riegner 1982a). I observed several Yellow-crowned Night Herons foraging during November and December...Nocturnal foraging; Bahamas; Nycticorax violacevs1985
411 Goller, FranzNonlinear model predicts diverse respiratory patterns of birdsongA 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; Song2006
412 Davidson, Diane W.Nonnative brome grasses in the new national monumentIncluded within the boundaries of the Grand-Staircase Escalante National Monument are a number of noxious weeds for which the BLM mandates control. In addition to listed weeds are nonnative brome grasses [Bromus tectorum and Bromus rubens), which can potentially convert native ecosystems to biologic...Noxious weeds, Cheatgrass,1998
413 Thomas, Kirk R.; Capecchi, Mario R.Nonreciprocal exchanges of information between DNA duplexes coinjected into mammalian. cell nucleiWe have examined the mechanism of homologous recombination between plasmid molecules coinjected into cultured mammalian cells.

414 Olivera, Baldomero M.; Bulaj, GrzegorzNovel conantokins from Conus parius venom are specific antagonists of N-methyl-D-aspartate receptorsWe report the discovery and characterization of three conantokin peptides from the venom of Conus parius. Each peptide (conantokin-Pr1, -Pr2, and -Pr3) contains 19 amino acids with three γ-carboxyglutamate (Gla) residues, a post-translationally modified amino acid characteristic of conantokins. The...Conotoxins; Conantokins; Conus parius; Antagonists; n-methyl-D-aspartate receptors2007
415 Olivera, Baldomero M.Novel Conus peptide ligand for K+ channelsVoltage-gated ion channels determine the membrane excitability of cells. Although many Conus peptides that interact with voltage-gated Na+ and Ca2+ channels have been characterized, relatively few have been identified that interact with K+ channels. We describe a novel Conus peptide that intera...Conus peptides; Conotoxins2003
416 Coley, Phyllis D.; Kursar, Thomas A.Novel DNA-based microfluorimetric method to evaluate antimalarial drug activityThis paper describes the development of a novel microfluorimetric assay to measure the inhibition of Plasmodium falciparum based on the detection of parasitic DNA by intercalation with PicoGreen®.

418 Olivera, Baldomero M.Novel venom peptides from the cone snail Conus pulicarius discovered through next-generation sequencing of its venom duct transcriptomeThe 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
419 Olivera, Baldomero M.; McIntosh, J. MichaelNuclear magnetic resonance solution conformation of α-conotoxin AuIB, an α3ß4 subtype-selective neuronal nicotinic acetylcholine receptor antagonistThe neuronal nicotinic acetylcholine receptors constitute a highly diverse group, with subtypes consisting of pentameric combinations of α and ß subunits. α-Conotoxins are a homologous series of small peptides that antagonize these receptors.

420 Beckerle, Mary C.Nuclear-cytoplasmic shuttling of the focal contact protein, zyxin: a potential mechanism for communication between sites of cell adhesion and the nucleusIntegrin-dependent cell adhesion to specific extracellular matrix molecules has been demonstrated to trigger dramatic changes in gene expression that can affect cell fate. However, little is understood about the molecular mechanism by which events at sites of cell-substratum adhesion are communicate...Zyxin; Cytosol; Nuclear export signal1997
421 Seger, JonNumerical method for estimating coefficients of relationship in a langur troopThe average coefficient of relationship ( r ij) among the members of a social group is expected to influence the evolution of any trait that affects the average fitness of group members other than the bearer of the trait. It is usually impossible to write a general expression for r ij , because it...Mating; Reproduction; Trait1977
422 Sperry, John S.Observations of reaction fibers in leaves of dicotyledonsHALLE, OLDEMAN, AND TOMLINSON (1978) have discussed the transference of function between compound leaves and plagiotropic branches in the context of tree architecture. In trees conforming to Cook's model (see Halle, Oldeman, & Tomlinson, 1978), plagiotropic branches resemble compound leaves in their...Reaction fibers; Compound leaves1982
423 Sperry, John S.Observations on the structure and function of hydathodes in Blechnum lehmaniiThe fronds of many ferns in the Polypodiaceae (Ogura, 1972) and Cyatheaceae (Weiler, cited in Lippmann, 1925) possess swollen vein endings associated with specialized adaxial epidermal cells. Their structure is similar in all ferns (Gardiner, 1883; Potonie, 1892; Poirault, 1893; Goebel, 1930; Gutten...Hydathodes; Blechnum lehmannii; Root pressure; Secretion1983
424 Crespo, Jose GuillermoOlfactory modulation of pre-flight shivering behavior in male mothsIn 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: Biology2011-01-02
