Bastiani, Michael | Loss of axons in the cat optic nerve following fetal unilateral enucleation: an electron microscopic analysis | Between the 48th day of gestation (E-48) and maturity, the number of axons in the cat optic nerve is reduced by approximately 50%. On the basis of an electron microscopic assay, the axon population of the E-48 nerve was estimated to be 328,000. In contrast, estimates from two normal adults were 159,... | Ganglion cell death; Retinofugal projection; Retinal ganglion cell axons | 1983 |

Goller, Franz | Low-dimensional dynamical model for the diversity of pressure patterns used in canary song | During song production, oscine birds produce large air sac pressure pulses. During those pulses, energy is transferred to labia located at the juncture between the bronchii and the trachea, inducing the high frequency labial oscillations which are responsible for airflow modulations, i.e., the utt... | Serinus canarias; Air sac pressure | 2009-04 |

Linton, Matthew J. | Magnitude and mechanisms of disequilibrium between predawn plant and soil water potentials | Predawn plant water potential (Uw, measured with leaf psychrometers) and surrogate measurements made with the pressure chamber (termed Upc here) are used to infer comparative ecological performance, based on the expectation that these plant potentials reflect the wettest soil Uw accessed by roots.

Adler, Frederick R.; Feener, Donald H. | Maintaining diversity in an ant community: modeling, extending, and testing the dominance-discovery trade-off | Ant communities often consist of many species with apparently similar niches. We present a mathematical model of the dominance-discovery trade-off, the trade-off between the abilities to find and to control resources, showing that it can in principle facilitate the coexistence of large numbers of s... | Coexistence; Dominant species; Parasitoid | 2007 |

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 |

Bohs, Lynn A. | Major clades in Solanum based on ndhF sequence data | Analysis of sequence data from the chloropiast gene ndhF identifies at least 12 major well-supported clades within the genus Solanum. These are briefly described, given informal clade names, and compared with the groups recognized by previous Solanum workers. Non-molecular synapomorphies are propos... | Solanum; ndhF | 2005 |

Potts, Wayne K. | Major histocompatibility complex heterozygote superiority during coinfection | Genes of the major histocompatibility complex (MHC) play a critical role in immune recognition, and many alleles confer susceptibility to infectious and autoimmune diseases. How these deleterious alleles persist in populations is controversial. | Pathogen; MHC; Homozygotes | 2003 |
