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...

Benthic macroinvertebrates and sediment characteristics of a coastal dune margin lake (Carter Lake, Douglas County, Oregon)

Creator:

Wones, Andrew G.

Abstract:

Carter Lake, a freshwater, coastal dune-margin lake, was sampled at the beginning and end of the summer of 1986 to determine the sediment characteristics and benthic macroinvertebrate abundance, biomass, variety, and diversity. The distributions of major benthic habitats were estimated by snorkeling in June and July, 1986. Water temperature and...
