The uptake, retention, and distribution of ⁶⁰Co, ⁶⁵Zn, ⁸⁵Sr, and ¹³¹I in the rough-skinned newt (Taricha Granulosa) : A radio-ecological study

Creator:: Valett, Bryan Batson
Abstract:: The uptake, retention, and distribution of ⁶⁰Co, ⁶⁵Zn, ⁸⁵ Sr, and ¹³¹I was examined in the Rough-Skinned Newt (Taricha granulosa). Each of these radionuclides is a possible contaminant of the freshwater environment and, thus, is of importance in radioecology. The newts were maintained singly at 10° C in an unfed...

The visual response of the purple shore crab, Hemigrapsus nudus, to ionizing and non-ionizing radiation

Creator:: Jordan, Neil Michael
Abstract:: Bioelectric responses from the isolated eye of the purple shore crab were measured by the electroretinogram with stimulation by light from wavelengths of 250 to 800 nm, strontium-yttrium-90 beta radiation, 17.5 keV x-radiation, and 3-cm microwaves. Peak sensitivities to light stimulation were found at 350 and 500 nm. These peaks...

Behavioral and electrophysiological evidence for the mechanisms involved in the detection of ionizing radiations by the crayfish Pacifastacus trowbridgii

Creator:: Rodriguez, Adrian
Abstract:: The light-adapted crayfish, Pacifastacus trowbridgii (Stimpson, 1957), displayed a behavioral response to exposure to 300 kV x-rays at exposure rates of 10 to 30 R/s. Within this range, the proportion of subjects that responded increased with an increase in exposure rate. The response latency was inversely proportional to the exposure...

The uptake and retention of cesium-134 in Microtus canicaudus Miller

Creator:: Lei, Wayne
Abstract:: A study was performed to assess the uptake and retention patterns of cesium-134 in the gray-tailed vole, Microtus canicaudus Miller. To furnish a realistic source of contaminated food for the voles, wheat seedlings were raised in hydroponic solutions to provide radiocesium labeled wheat clippings. The hydroponic system was designed to...

Some possible roles for selenium in the reproductive physiology of the male graytailed vole (Microtus canicaudus)

Creator:: Whitfield, Stephen Curtiss
Abstract:: The testes of the gray-tailed vole (Microtus canicaudus Miller) exhibited a high affinity for selenium relative to other selected tissues. Uptake of selenium-75 in the testis-epididymis complex was delayed relative to uptake by the whole body, kidney, and liver. This pattern of uptake suggested that selenium was metabolically incorporated into...

Effects of fractionated radiation doses on survival times of the newt (Taricha granulosa)

Creator:: Campbell, Carol Lee
Abstract:: This was a study designed to determine the occurrence of recovery from radiation damage in Taricha granulosa. Irradiation with either gamma or x-ray sources in the range of 96-10,000 rads was given. (The mean or median survival times were determined.) Doses were fractionated and the survival times for the same...

Exposure to ultraviolet-B radiation : sensitivity evaluation of an important ecological parameter of the marine copepod Acartia clausi

Creator:: Karanas, James J.
Abstract:: The ozone present in the atmosphere filters incident solar ultraviolet (UV) radiation such that only the longer wavelengths of the total UV spectrum emitted by the sun reach the earth's surface. Atmospheric increases in nitrogen oxides and chlorofluoromethanes represent a threat to the existence of this protective screen. As the...

The lethal response of the roughskin newt, Taricha granulosa (Skilton), to ultraviolet-B radiation at three fluence rates

Creator:: Michaelis, Barbara
Abstract:: Roughskin newts, Taricha granulosa (Skilton), were exposed to UV-B (280-320nm), UV-A (321-380 nm), and visible radiation from fluorescent sunlamps (Westinghouse FS40) that were filtered with cellulose acetate film. UV-B controls were exposed to irradiation from sunlamps that were filtered with Mylar-D, a polyester film that effectively absorbed UV-B radiation while...
