New concepts regarding the production of waterfowl and other game birds in areas of diversified agriculture
H.K. Nelson, Harold F. Duebbert
1974, Book chapter
Many concepts regarding breeding ecology of waterfowl and the influences of environmental factors on annual production have changed in the past 20 years. These influences are especially pronounced in the prairie region of central North America where agriculture becomes more intensive each year. The principal task assigned to this Research...

Erosion by catastrophic floods on Mars and Earth
V.R. Baker, D.J. Milton
1974, Icarus (23) 27-41
The large Martian channels, especially Kasei, Ares, Tiu, Simud, and Mangala Valles, show morphologic features strikingly similar to those of the Channeled Scabland of eastern Washington, produced by the catastrophic breakout floods of Pleistocene Lake Missoula. Features in the overall pattern include the...
Social behavior of breeding gadwalls in North Dakota
T.J. Dwyer
1974, The Auk (91) 375-386
Responses of duck pairs encountering other ducks were categorized by McKinney (1965a) as displays, attack, escape and avoidance, sexual pursuit, and sociability. Gadwalls (Anas strepera) show all these responses on the breeding grounds, and characteristic behavior patterns occur depending on the reproductive state of the birds involved. The responses of...
The regolith at the Apollo 15 site and its stratigraphic implications
M. H. Carr, C.E. Meyer
1974, Geochimica et Cosmochimica Acta (38) 1183-1197
Regolith samples from the Apollo 15 landing site are described in terms of two major fractions, a homogeneous glass fraction and a non-homogeneous glass fraction. The proportions of different components in the homogeneous glass fraction were determined directly by chemical analyses of individual...
New seismic study begins in Puerto Rico
Arthur C. Tarr
1974, Earthquake Information Bulletin (USGS) (6) 23-26
A new seismological project is now underway in Puerto Rico to provide information needed for accurate assessment of the island's seismic hazard. The project should also help to increase understanding of the tectonics and geologic evolution of the Caribbean region. The Puerto Rico Seismic Program is being conducted by the...

What is the possibility that an earthquake will occur near you? Have you ever wondered what the chances were that an earthquake could affect you at home or at work? Perhaps you are planning to move to a part of the country subject to frequent earthquakes. How do you determine...
Prolonged incubation behavior by a marbled godwit
K.F. Higgins
1974, The Auk (91) 167-167
On 9 May 1972 I flushed a Marbled Godwit (Limosa fedoa) from a nest containing four eggs in a large field of mulched wheat stubble in northwestern Stutsman County, North Dakota. I revisited the nest on 31 May and on 7, 9, 12, 15, 16, 20, and 21 June, and...
Comparison of elemental accumulation rates between ferromanganese deposits and sediments in the South Pacific Ocean
T. Kraemer, J.C. Schornick
1974, Chemical Geology (13) 187-196
Rates of accumulation of Fe and Mn, as well as Cu, Ni, Co, Pb, Zn, Hg, U and Th have been determined for five ferromanganese deposits from four localities in the South Pacific Ocean.Manganese is accumulating in nodules and crusts at a rate roughly equivalent to that found...
An attempt to age mallards using eye lens proteins
Charles J. Henny, J. Larry Ludke
1974, Journal of Wildlife Management (38) 138-141
An analysis of insoluble protein content of eye lenses from 59 known-age mallards (Anas platyrhynchos) indicated a slight increase between 8-9 months and 7 years of age. Nearly a complete overlapping of the insoluble protein content of individuals of different ages was apparent showing that the technique cannot be used...

Seismicity and earthquake hazards of the Wasatch Front, Utah
H. Spall
1974, Earthquake Information Bulletin (USGS) (6) 12-17
The impressive topographic break at the base of the Wasatch Range immediately east of Salt Lake City, Utah, marks the location where Mormon colonizer Brigham Young said in 1847. "This is the place" Actually, "the place" is termed the Wasatch Front because the Wasatch Range to the east, which rises...
Earthquake prediction; new studies yield promising results
R. Robinson
1974, Earthquake Information Bulletin (USGS) (6) 14-17
On Agust 3, 1973, a small earthquake (magnitude 2.5) occurred near Blue Mountain Lake in the Adirondack region of northern New York State. This seemingly unimportant event was of great significance, however, because it was predicted. Seismologsits at the Lamont-Doherty geologcal Observatory of Columbia University accurately foretold the time, place,...
Laboratory experiments duplicate conditions in the Earth’s crust
L. Peselnick, James H. Dieterich, R.M. Stewart
1974, Earthquake Information Bulletin (USGS) (6) 10-15
An experimental device that simulates conditions in the Earth's crust at depths of up to 30 kilometers has been constructed by geophysicists working at the U.S Geological Survey laboratories in Menlo Park, California. A high pressure "bomb" is being used to experimentally measure the velocity of seismic waves in different...
The California geodimeter network; measuring movement along the San Andreas Fault
J.C. Savage
1974, Earthquake Information Bulletin (USGS) (6) 3-7
Following the great California earthquake of 1906 H. F. Reid, a contemporary seismologist, proposed the elastic rebound theory which in effect says that earthquake potential arises from the accumulation of elastic strain within the Earth's crust, just as the stretching of a rubberband creates the potential for violent rebound upon...
Searching for prehistoric earthquakes in lake sediments
J. Sims
1974, Earthquake Information Bulletin (USGS) (6) 3-9
How often do major earthquakes occur? Do they follow regular patterns of recurrence, and if so, what is the length of the recurrence interval? These questions are of obvious importance to populations located in regions where earthquakes are a commonplace occurrence. They are also relevant questions in regions that are...
