The associates of four species of marine sponges of Oregon and Washington

Creator:: Long, Edward R.
Abstract:: Four species of sponge from the coasts of Oregon and Washington were studied and dissected for inhabitants and associates. All four species differed in texture, composition, and habitat, and likewise, the populations of associates of each species differed, even when samples of two of these species were found adjacent to...

The morphology and ecology of Echinorhynchus lageniformis Ekbaum, 1938 (Acanthocephala)

Creator:: Barnes, James R.
Abstract:: The acanthocephalan Echinorhynchus lageniformis Ekbaum, 1938, is a common intestinal parasite of the starry flounder, Platichthys stellatus (Pallas), of Yaquina Bay, Lincoln Co., Oregon. Three hundred and sixty-one flounders were examined and 146 (40.5 percent) were found to harbor infections of E. lageniformis. Cystacanths of E. lageniformis were found encysted...

Effects of temperature on the development of Fasciola hepatica larval forms in Lymnea columella

Creator:: Wall, David Jerome
Abstract:: Lymnea columella snails were exposed to 3-5 newly emerged Fasciola hepatica miracidia. The procedure insured 75-100 percent infection of the host. Groups of 40 each exposed snails were placed in controlled temperature containers and maintained at the following series of temperatures: 8°, 15°, 20°, 25°, 30°, and 35° C. Two...

The life history of Neoechinorhynchus rutili (Mueller, 1780) and its development in the intermediate host (Acanthocephala ; Neoechinorhychidae)

Creator:: Merritt, Sheridan Vernon
Abstract:: The fish of Suttle Lake, Oregon, have been found to harbor an acanthocephalan parasite, which lives attached to the mucosa of the intestine. Between July 1961 and January 1963, several hundred of these fish were exarnined and nearly every one was infected with this parasite, which was identified as Neochinorhynchus...

Life cycle and host specificity of Diclidophora sp. (Monogenea-Diclidophoridae), a parasite of embiotocid fishes

Creator:: Hanson, Alfred Warren
Abstract:: The life cycle of a monogenean, Diclidophora sp., was studied with special attention to the time required for developmental stages to occur. Eggs are produced by adult worms at the rate of one every 13.5 minutes and require 32 days to hatch when incubated at 12.5°C and 30.9‰ salinity. Rate...

The algal symbionts of the solitary green sea anemone Anthopleura xanthogrammica

Creator:: Hartman, Michael Colyn
Abstract:: The anemone Anthopleura xanthogrammica varies in color from bright green to muddy brown. However, individuals found in caves are white. White specimens of Anthopleura xanthogrammica collected from dark caves along the Oregon coast were subjected to various experiments to determine if these cave dwelling animals carried any cells of the...
