301 Jorgensen, ErikInterferometric localization microscopyInterference of signal in Fourier space, emitted from single probes, is used to localize it by recording and computing the phase of the fringes. Such system has applications in super resolution localization microscopy.2014-01-01
302 Ehleringer, James R.Interspecific competition and resource pulse utilization in a cold desert communityIn desert ecosystems a large proportion of water and nitrogen is supplied in rain-induced pulses. It has been suggested that competitive interactions among desert plants would be most intense during these pulse periods of high resource availability. We tested this hypothesis with three cold desert s...Atriplex confertifolia; Chrysothamnus nauseosus; Colorado Plateau; desert; Gutierrezia sarothrae; Neighbor removal; Plant competition; Resource pulses; Pulse utilization; Stable isotopes; Water uptake2002
303 Ehleringer, James R.Intra- and interspecific variation for summer precipitation use in pinyon-juniper woodlandsIn the arid southwest of North America, winter precipitation penetrates to deep soil layers, whereas summer"monsoon" precipitation generally wets only surface layers. Use of these spatially separated water sources was determined for three dominant tree species of the pinyon-juniper ecosystem at six ...D/H ratios; Juniperus osteosperma; Pinus edulis; pinyon-juniper ecosystem; plant water sources; precipitation use; Quercus gambelii; roots; Photosynthetic gas exchange; Monsoon2000
304 Seger, JonIntraspecific resource competition as a cause of sympatric speciation[In most models of speciation], the fitness value of an animal is determined by the genotype it has, and the habitat in which it lives. In a more realistic model it should also depend on how much necessary resource is available for the animal and the competition from other genotypes for this resourc...Phenotype; Models; Species1985
305 Coley, Phyllis D.Intraspecific variation in herbivory on two tropical tree speciesLevels of herbivory on young and mature leaves were determined for two tree species, Trichilia cipo (Meliaceae) and Cecropia insignis (Moraceae), in a lowland rain forest of Panama. Saplings of both species were studied in light gaps, and in addition, Trichilia was studied in the understory.Cecropia insignis; Trichilia cipo; Herbivory; Intraspecific variation; Panama; Temporal distribution; Treefall gaps; Tropical forest; Understory1983
306 Mansour, Suzanne L.; Thomas, Kirk R.; Capecchi, Mario R.Introduction of a lacZ reporter gene into the mouse int-2 locus by homologous recombination.We demonstrate that the frequency of gene targeting is unaffected by the length of nonhomologous DNA transferred to a target chromosomal sequence. A result of this finding is that a much wider spectrum of designed genomic alterations is now feasible. As a first application, we inserted a 5.4-kilobas...Blotting, Southern; Cell Differentiation; Fluorescent Antibody Technique; Restriction Mapping1990-10
307 Thomas, Kirk R.; Capecchi, Mario R.Introduction of homologous DNA sequences into mammalian cells induces mutations in the cognate gene.Injection of homologous DNA sequences into nuclei of cultured mammalian cells induces mutations in the cognate chromosomal gene. It appears that these mutations result from incorrect repair of a heteroduplex formed between the introduced and the chromosomal sequence. This phenomenon is termed 'heter...Animals; Cell Line; Drug Resistance, Microbial; Fibroblasts; Mice; Models, Genetic; Neomycin; Plasmids1986-11-06
308 Capecchi, Mario R.Introduction: the molecular genetic analysis of mouse developmentThis paper is an introduction of seven different papers presented in "Seminars in developmental biology" on Molecular Genetic Analysis of Mouse Development .

309 Olivera, Baldomero M.; Gray, William RobertInvertebrate vasopressin/oxytocin homologs: characterization of peptides from Conus geographus and Conus striatus venomsThe vasopressin-oxytocin family of peptides is of very ancient lineage, found in organisms as diverse as hydra and man. Although these peptides have been intensively studied in vertebrates, the presumably more extensive invertebrate series was defined primarily by immunological methods. In this repo...Conus geographus; Conus striatus; Venom; Conotoxins; Neurotoxins; Postsynaptic inhibition; Vasopressin-oxytocin peptides; Conopressin1987
310 Clayton, Dale H.; Bush, Sarah ElizabethIs melanin a defense against feather-feeding lice?The adaptive basis of plumage color has received much attention, including the finding that color can reveal information about parasite loads to potential mates. A related possibility, that color may be a direct defense against parasites, has received less attention.Columba livia; Columbiformes; Ectoparasites; Columbicola columbae; Campanulotes compare; Plumage color; Eumelanin; Preening2006
311 Adler, Frederick R.Is space necessary? Interference competition and limits to biodiversityA single trade-off between competitive ability and mortality has been shown to support an arbitrarily large number of species in models of interference competition in spatially structured populations. We show that this results not from spatial structure, but instead from the assumption that a small ...Mortality rate; Competitive ability; Seed size2000
312 Olivera, Baldomero M.; McIntosh, J. MichaelIsolation and characterization of a novel Conus peptide with apparent antinociceptive activityCone snails are tropical marine mollusks that envenomate prey with a complex mixture of neuropharmacologically active compounds. We report the discovery and biochemical characterization of a structurally unique peptide isolated from the venom of Conus marmoreus. The new peptide, mr10a, potently incr...Conotoxins; Conus peptides; Conus marmoreus; mr10a; antinociceptive activity2000
313 Capecchi, Mario R.Isolation and characterization of Caenorhabditis elegans DNA sequences homologous to the v-abl oncogene.DNA sequences homologous to the v-abl oncogene were isolated from a Caenorhabditis elegans genomic library by their ability to hybridize with a v-src probe. The DNA sequence of 2465 nucleotides of one clone was determined. This region corresponds to the 5' protein kinase domain of v-abl plus approxi...Amino Acid Sequence; Animals; Base Sequence; Gene Expression Regulation; Transcription, Genetic1986-04
314 Capecchi, Mario R.Isolation of a suppressible nonsense mutant in mammalian cellsAn HGPRT- cell line derived from mouse L cells has been shown to have the following properties: it is CRM'; the defective HGPRT molecules are altered in the carboxyterminal peptide; the mutant cells regain HGPRT activity when ochre-suppressor tRNA is microinjected into them, but not when amber...HGPRT cell line; HGPRT activity; Ochre nonsense mutation; Mouse L cells; Mammalian cells1977
315 Bohs, Lynn A.ITS phylogeny of Balsamorhiza and Wyethia (Asteraceae: Heliantheae)The relationships among the species of Balsamorhiza and Wyethia (Asteraceae: Heliantheae) were examined using data from the internal transcribed spacer (ITS) region of the nuclear ribosomal DNA.
