Clay minerals: A guide to their x-ray identification
Dorothy Carroll
1970, Book
This paper is a guide to the X-ray examination of clay minerals; it incorporates background information concerning the principal crystallographic features of clay minerals, and how this is used in the X-ray identification of these minerals, together with laboratory techniques and the application of X-ray diffractometry to the diagnosis of...
Palynology of the Cretaceous-Tertiary boundary in the northern Rocky Mountain and Mississippi Embayment regions
Robert H. Tschudy
Robert M. Kosanke, Aureal T. Cross, editor(s)
1970, Book chapter, Symposium on Palynology of the Late Cretaceous and Early Tertiary
In both the Rocky Mountain and the Mississippi Embayment regions it is often difficult to distinguish Upper Cretaceous from lower Tertiary rocks on the basis of physical characteristics; the transition can be recognized with relative ease, however, on the basis of abrupt qualitative changes in plant microfossils. Many Cretaceous species...

On the theory of evolution of river nets
A. E. Scheidegger
1970, International Association of Scientific Hydrology - Bulletin (15) 109-114
An investigation is made of the growth of river basins based on the two current models of the structure of such basins: the cyclic model and the random-graph model. Based on the assumption that the networks grow allometrically, the structure of the network that evolves has...

A brief history of commercial fishing in Lake Erie
Vernon C. Applegate, Harry D. Van Meter
1970, Fishery Leaflet 630
Salient features of the development of the industry from about 1815 to 1968, changes in fishing gears and methods, changes in the kinds and abundance of fishes caught, and the attendant effects of disappearing species on the stability of the fishery are described. The history and present status of the...

Let's Sing 'Auld Lang Syne' for the Upper Brandywine: Or, to continue with Burns, how the best laid environmental schemes of men "gang aft a-gley"
Luna Bergere Leopold
1970, Natural History (79) 5-15
Perhaps the most lamentable mistake that one can make is to be right too soon. This was the story of the Brandywine Plan, an attempt to organize local people for the permanent protection of the environmental amenities of their own land.The Upper East Branch of Brandywine Creek drains a rolling...

Morphology of certain viruses of Salmonid Fishes. I. in vitro studies of some viruses causing Hematopoietic Necrosis
Donald F. Amend, Velma C. Chambers
1970, Journal of the Fisheries Research Board of Canada (27) 1285-1293
An electron microscope study was performed on three virus isolates that caused hematopoietic necrosis in salmonid fishes: infectious hematopoietic necrosis (IHN), Oregon Sockeye Disease (OSD), and Sacramento River Chinook Salmon Disease (SRCD). All three isolates were examined by negative staining of fathead minnow (FHM) monolayer tissue culture concentrates and IHN...

Retention of mercury by salmon
Donald F. Amend
1970, Progressive Fish-Culturist (32) 192-194
Consuming fish that have been exposed repeatedly to mercury derivatives is a potential public health hazard because fish can accumulate and retain mercury in their tissues (Rucker, 1968). Concern has been expressed in the United States because mercurials have been used extensively in industry and as prophylactic and...

Stress of anesthesia with M.S. 222 and Benzocaine in Rainbow Trout (Salmo gairdneri)
Gary Wedemeyer
1970, Journal of the Fisheries Research Board of Canada (27) 909-914
Rainbow trout (Salmo gairdneri) anesthetized with M.S. 222 for periods up to 12 min experience interrenal ascorbate depletion, uremia, and moderate hypercholesterolemia. Anesthesia with neutralized M.S. 222 (pH 7) or benzocaine prevented these changes and significantly reduced the variability in plasma glucose, cholesterol, and cortisol, indicating that the stress of anesthesia...
Extreme female predominance in the bloater (Coregonus hoyi) of Lake Michigan in the 1960's
Edward H. Brown Jr.
C.C. Lindsey, C.S. Woods, editor(s)
1970, Book chapter, Biology of coregonid fishes
The sex composition and other biological characteristics of the bloater changed substantially during recent decades of continuous ecological change in Lake Michigan. The percentages of females increased from 72% of the bloaters samples in 1928-32 to 95% in 1963, and ranged from 94 to 97% in 1964-69. The unusual predominance...
Testing of selected pharmacological agents for capturing waterfowl [Annual Progress Report]
D.R. Cline
1970, Report
The response of game-farm mallards (Frost strain) to seven pharmacological immobilizing agents was evaluated in Phase I of a planned four-phase study. A limited amount of testing was also done with wild mallards. Single dosages were administered to determine the mean effective dose (ED50) and mean lethal dose (LD50), The...
Temperature tolerance of young-of-the-year cisco, Coregonus artedii
Thomas A. Edsall, Peter J. Colby
1970, Transactions of the American Fisheries Society (99) 526-531
Young-of-the-year ciscoes (Coregonus artedii) acclimated to 2, 5, 10, 20 and 25 C and tested for tolerance to high and low temperatures provide the first detailed description of the thermal tolerance of coregonids in North America. The upper ultimate lethal temperature of the young ciscoes was 26 C (6 C...
Resource crises in Lake Erie
Wilbur L. Hartman
1970, Explorer (12) 6-11
Despite the tremendous value of the Great Lakes, a malaise is seriously destroying their worth. Accelerated enrichment, unabated pollution, over-exploitation, and accidental and intentional introduction of exotic species, have all been guided--more often misguided--by man. Of all five Great Lakes, Lake Erie stands out as the one most...
Winds over saltcedar
T. E. A. Van Hylckama
1970, Agricultural Meteorology (7) 217-233
An analysis of hourly wind speeds above and within a stand of saltcedar near Buckeye, Arizona, reveals that in 90% of all observed cases, the wind profiles above the stand can be represented by the simple logarithmic equation: uz=u*k1n">uz=u*k1n (zz0)">zz0) where...
Foraminiferal zonation and carbonate facies of Carboniferous (Mississippian and Pennsylvanian) Lisburne group, central and eastern Brooks range, Arctic Alaska
Augustus K. Armstrong, Bernard L. Mamet, J. Thomas Dutro
1970, American Association of Petroleum Geologists Bulletin (54) 687-698
The Lisburne Group carbonate rocks of the central and eastern Brooks Range contain foraminiferal assemblages assigned to zones of late Tournaisian (Osage) to early Moscovian (Atoka) age. Representatives of both Eurasiatic and American cratonic microfaunas permit correlation with the original Carboniferous type sections in western Europe as well as with...
Latitudinal gradients in tertiary molluscan faunas of the Pacific coast
W.O. Addicott
1970, Palaeogeography, Palaeoclimatology, Palaeoecology (8) 287-312
Tertiary molluscan faunas of the middle latitudes of the marginal eastern North Pacific are characterized by warm-water taxa whose descendants now live in more southerly latitudes. A series of profiles in which cumulative percentages of warm-water faunal elements are plotted against latitude show progressive northward decreases in the percentage of...
Geothermal resources of the northern gulf of Mexico basin
P.H. Jones
1970, Geothermics (2) 14-26
Published geothermal gradient maps for the northern Gulf of Mexico basin indicate little or no potential for the development of geothermal resources. Results of deep drilling, from 4000 to 7000 meters or more, during the past decade however, define very sharp increases in geothermal gradient which are associated with the...
