Search for blood protozoans in the American woodcock
W.B. Krohn, J.R. Hynson
1975, Journal of Wildlife Diseases (11) 107-108
Smears were prepared from heart blood of 55 woodcock collected in central Maine between spring and fall, 1972 and 1973. Peripheral blood taken from the wings of 41 of these birds also was examined. Examination of stained films revealed no infected blood cells. Samples of heart blood from 35 of...

History of fish toxicants in the United States
K.B. Cumming
1975, Special Publication 4
Many bodies of water have been overrun with fish species that are undesirable for the well-being of endemic aquatic biota and are of little or no interest to anglers. This situation has resulted from the transplanting of fish, creation of new waters, increasing fishing pressure and changing water quality. Although...

Mercury distribution in ancient and modern sediment of northeastern Bering Sea
C.H. Nelson, D.E. Pierce, Kam Leong, F.F.H. Wang
1975, Marine Geology (18) 91-104
Reconnaissance sampling of surface and subsurface sediment to a maximum depth of 80 m below the sea floor shows that typical values of 0.03 p.p.m. and anomalies of 0.2-1.3 p.p.m. mercury have been present in northeastern Bering Sea since Early Pliocene time. Values are highest in modern beach (maximum 1.3...
Streamflow characteristics in northeastern Utah and adjacent areas
Fred K. Fields
1975, Utah Basic-Data Release 25
This report contains statistical summaries of streamflow records from 74 gaging stations, which are mostly in northeastern Utah. Low- flow, high-flow, and flow-duration summaries were compiled from daily discharge values; and flows of each month are compared through correlation with flows of 1, 2, and 12 months in the future....
Duck plague: carrier state and gross pathology in black ducks
Jorge E. Ossa
1975, Thesis
Duck plague (UP) is a highly fatal disease of ducks, geese, and swans (family Anatidae), produced by a reticulo-endotheliotrophic virus classified as a member of the Herpesvirus group. The disease was recognized in Europe in 1949. On the American continent, the disease was first diagnosed in the United States in...
Pathophysiology of infectious hematopoietic necrosis virus disease in rainbow trout: Hematological and blood chemical changes in moribund fish
D.F. Amend, L. Smith
1975, Infection and Immunity (11) 171-179
Infectious hematopoietic necrosis (IHN) is a rhabdoviral disease of rainbow trout (Salmo gairdneri). Trout were injected with IHNV, and various hematological and biochemical measurements of clinically ill fish were compared to uninfected controls. Infected fish had reduced corpuscular counts, hemoglobin, and packed cell volume, but normal mean corpuscular volume, mean...
Gas bubble disease: mortalities of coho salmon, Oncorhynchus kisutch, in water with constant total gas pressure and different oxygen-nitrogen ratios
R.R. Rucker
1975, Fishery Bulletin (73) 915-918
A review of the literature regarding gas-bubble disease can be found in a recent publication by Rucker (1972); one by the National Academy of Science (Anonymous in press); and an unpublished report by Weitkamp and Katz (1973)." Most discussions on gas-bubble disease have dealt with the inert gas, nitrogen-oxygen was...
Longevity of nonsprouting Ceanothus
Jon E. Keeley
1975, American Midland Naturalist (93) 504-507
Evidence is presented indicating species of Ceanothus in the subgenus Cerastes are generally longer-lived than species in the subgenus Euceanothus. It is proposed that this is due, at least in part, to the unique stem morphology of the former. The stems of these plants have a ribbed appearance which arises...
Rare earths in the Leadville Limestone and its marble derivates
J.C. Jarvis, T.R. Wildeman, N.G. Banks
1975, Chemical Geology (16) 27-37
Samples of unaltered and metamorphosed Leadville Limestone (Mississippian, Colorado) were analyzed by neutron activation for ten rare-earth elements (REE). The total abundance of the REE in the least-altered limestone is 4–12 ppm, and their distribution patterns are believed to be dominated by...
Canister cryogenic system for cooling germanium semiconductor detectors in borehole and marine probes
G. R. Boynton
1975, Nuclear Instruments and Methods (123) 599-603
High resolution intrinsic and lithium-drifted germanium gamma-ray detectors operate at about 77–90 K. A cryostat for borehole and marine applications has been designed that makes use of prefrozen propane canisters. Uses of such canisters simplifies cryostat construction, and the rapid exchange of canisters...
Determining earthquake recurrence intervals from deformational structures in young lacustrine sediments
John D. Sims
1975, Tectonophysics (29) 141-152
Examination of the silty sediments in the lower Van Normal reservoir after the 1971 San Fernando, California earthquake revealed three zones of deformational structures in the 1-m-thick sequence of sediments exposed over about 2 km2 of the reservoir bottom. These zones are correlated with moderate earthquakes that shook the San Fernando...

Productivity and flowering of winter ephemerals in relation to Sonoran Desert shrubs
William L. Halvorson, Duncan T. Patten
1975, American Midland Naturalist (93) 311-319
Ephemeral plant biomass and density on a Sonoran Desert hill near Cave Creek, Arizona, vary relative to shrub canopy type and shrub density. Higher shrub density associated with increased elevation appears to decrease both ephemeral biomass productivity and density, while ephemeral growth is enhanced under a shrub canopy if it...
