  2. The red-tailed hawk on Sauvie Island, Oregon

    A study was undertaken to determine the abundance, distribution, perching heights, diets and territory sizes of Red-Tailed Hawks on Sauvie Island, Oregon. Sauvie Island supported a large wintering population of...

  3. Survivorship and Breeding Dispersal Patterns of a Migratory, Socially Monogamous Passerine; the Scissor-tailed Flycatcher...

    Survivorship (the likelihood of survival from one year to the next) and breeding dispersal (movement between breeding seasons) exhibit considerable variability at both the inter- and intraspecific levels. Using...

  4. A Flux-Focusing Cycloidal Magnetic Gearbox

    This paper investigates the performance of a -25:1 gear ratio cycloidal magnetic gearbox (CMG) with a flux-focusing rotor topology. The performance of the CMG is investigated by conducting an iterative...

  5. Observations on the establishment of seedlings of Phoradendron californicum on Prosopis juliflora

    The mistletoe Phoradendron californicum is a common parasite on the mesquite plant Prosopis juliflora. Seeds of the parasite are deposited upon the host plant by birds and perhaps other agents. Normally...

  6. Lactic dehydrogenase isozyme isolation by disc electrophoresis in eight species of fringillid birds

    Disc electrophoresis of tissue homogenates from eight species of fringillid birds showed five forms of lactic dehydrogenase. The relative amounts of isozymes were characteristic for each species. This paper...

  7. The Response of Mice to Infection by the Parasitic Nematode Trichinella: A Comparison of Trichinella Spiralis and Trichinella...
