Isolation and characterization of a larval crustacean salt gland from the brine shrimp Artemia salina

Creator:: Lowy, Robert Joel
Abstract:: A method for isolating the salt gland (SG) from the larval brine shrimp has been developed. This extra-renal organ is removed from 5-10% of Stage Inauplii by vortexing after incubating the animals at 37°C for 8 hours in a saline solution buffered with 100 mM sodium phosphate at pH 7.6....

An Osteo-archaeological Investigation of Pinniped Remains at Seal Rock, Oregon (35 LNC 14)

Creator:: Snyder, Sandra L.
Abstract:: Analysis of the pinniped remains from site 35 LNC 14 reveal the presence of four species: Eumetopias jubata (Stellar sea lion), Zalophus californianus (California sea lion), Callorhinus ursinus (Northern fur seal),'and Phoca vitulina (Harbor seal). Ratios based on minimum number of individuals calculations disclose a high incidence of mature Stellar...

Aboriginal fishing at Seal Rock (35-LC-14) and Neptune (35-LA-3) : late-prehistoric archaeological sites on the central Oregon coast

Creator:: Zontek, Terry
Abstract:: A sample of fish remains from two late-prehistoric archaeological sites on the central coast of Oregon were analyzed to partially evaluate two models of aboriginal subsistence-settlement systems. One model is based upon ethnograhpic data, primarily Drucker's (1939), for Yakonen speakers collected in the late 19th and early 20th centuries. The...

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 effects of external salinity on carbon dioxide incorporation into free amino acids in Artemia nauplii

Creator:: Carpenter, John Frank
Abstract:: In Artemia salina nauplii acclimated in 0.25 M, 0.5 M, 1.0 M, 1.5 M, 2.0 M, and 2.5 M NaCl incorporation of ¹⁴CO₂ into free amino acids was greatly stimulated in the higher salinities. The ¹⁴C label was found in aspartic acid, serine, glutamic acid, proline and alanine. Hypersalinity also...

An histochemical study of the changing patterns of glycogen distribution in the uterus of the early pregnant and lactating golden hamster (Mesocricetus auratus Waterhouse)

Creator:: Wicklund, Thomas Glen
Abstract:: This study deals with the histochemical identification of the changing patterns of glycogen in the uterus of the early pregnant and lactating golden hamster (Mesocricetus auratus Waterhouse). The uterus of the hamster representing days one through five of gestation, and one through ten, twelve, and fourteen of lactation, provided the...

Oxygen consumption of three species of sea urchins at different temperatures

Creator:: Ulbricht, Richard Jules
Abstract:: Metabolic rate-temperature responses of three related species of sea urchins were determined using oxygen consumption rate measurements. The three species used were Strongylocentrotus purpuratus, Strongylocentrotus franciscanus, and Allocentrotus fragilis. All measurements were made using an oxygen macro-electrode, physiological gas analyzer, and sealed respiratory container. Two series of experiments--field-acclimatized and temperature-acclimated--were...

Ecological physiology of the larvel brine fly Ephydra (Hydropyrus) hians, and alkaline-salt lake inhabiting Ephyrid (Diptera)

Creator:: Herbst, David B.
Abstract:: Dipterans of the family Ephydridae (shore and brine flies) are well known for their ability to tolerate and thrive in a wide variety of physically harsh circumstances. The immature stages of one such species of this family, Ephydra hians, are characteristically limited in distribution as benthic inhabitants of highly alkaline...

An ecological study of Diatomovora amoena, an interstitial acoel flatworm, in an estuarine mudflat on the central coast of Oregon

Creator:: Thum, Alan Bradley
Abstract:: The distribution and abundance of the interstitial acoel turbellarian, Diatomovora amoena Kozloff, 1965 was studied in an estuarine intertidal sand flat in Yaquina Bay, Oregon, from May 1970 through May 1971. Monthly measurements of biological (organics, sulfides, chlorophyll, and carotenoids), pore water (salinity, pH,oxygen, and temperature), and sediment (fine sediment...
