Model aids planners in predicting rising ground-water levels in San Bernardino, California
William F. Hardt, C. B. Hutchinson
1978, Groundwater (16) 424-431
The city of San Bernardino is in a semiarid inland valley about 60 miles (100 kilometers) east of Los Angeles. The southern part of the city is traversed by the San Jacinto fault. Adjacent to the upgradient (northeast) side of the fault is a 10 square mile (26 square kilometers)...
Low-cost computer classification of land cover in the Portland area, Oregon, by signature extension techniques
Leonard J. Gaydos
1978, Journal of Research of the U.S. Geological Survey (6) 815-819
Computer-aided techniques for interpreting multispectral data acquired by Landsat offer economies in the mapping of land cover. Even so, the actual establishment of the statistical classes, or "signatures," is one of the relatively more costly operations involved. Analysts have, therefore, been seeking cost-saving signature extension techniques that would accept training...

Lawrence R. Pettinger, Adrian Farmer, Mel Schamberger
1978, Conference Paper, Pecora IV: Proceedings of the symposium
The habitat value for elk and sage grouse of two proposed phosphate strip mine sites was determined using habitat parameter measurements from high-altitude color infrared aerial photographs. Habitat suitability was assessed using the Habitat Evaluation Procedures being developed by the U.S. Fish and Wildlife Service. Similar results were...
Trend analysis of vegetation in Louisiana's Atchafalaya river basin
Calvin P. O’Neil, J. Edward deSteiguer, Gary W. North
1978, Pecora IV Proceedings of the Symposium 114-136
The purpose of the study was to determine vegetation succession trends; produce a current vegetation map of the basin; and to develop a mathematical model capable of predicting vegetation changes based on hydrologic factors. A statistical relationship of forests and hydrological variables with forest succession constraints predicted forest acreage...

It can...
Statistical inference from capture data on closed animal populations
David L. Otis, Kenneth P. Burnham, Gary C. White, David R. Anderson
1978, Wildlife Monographs 3-135
The estimation of animal abundance is an important problem in both the theoretical and applied biological sciences. Serious work to develop estimation methods began during the 1950s, with a few attempts before that time. The literature on estimation methods has increased tremendously during the past 25 years (Cormack...
Metabolic indicators of habitat differences in four Minnesota deer populations
U.S. Seal, M.E. Nelson, L.D. Mech, R.L. Hoskinson
1978, Journal of Wildlife Management (42) 746-754
Blood samples were collected from 40 white-tailed deer (Odocoileus virginianus) from 4 winter yards in northeastern Minnesota from 17 March 1974 through 23 April 1975. The results of 26 blood assays were examined for the effects of age, sex, capture date, capture method, disease and location. Age-related effects were found...
Reappraising factors affecting mourning dove perch coos
M. W. Sayre, R.D. Atkinson, T.S. Baskett, G.H. Haas
1978, Journal of Wildlife Management (42) 884-889
Results confirmed pairing as the primary factor influencing perch-cooing rates of wild mourning doves (Zenaida macroura). Marked unmated males cooed at substantially higher rates (6.2x) than mated males, had greater probability of cooing (2.3x) during 3-minute periods, and continued cooing longer each morning than mated males. Population density was not...

K.C. Bayer, R.E. Mattick, T.R. Bruns, George Plafker
1978, Journal of Research of the U.S. Geological Survey (6) 625-636
Results of five seismic refraction lines shot by the U.S. Geological Survey in the Gulf of Alaska between Icy Bay and Kayak Island indicate the following: (1) The Continental Shelf is underlain by as much as 11 km of sedimentary rock of probable Tertiary age where refraction velocities range from 1.2 to 5.5 kilometers per...

Michael A. Bogan
1978, Journal of Mammalogy (59) 519-530
A new Myotis is described from the Islas Tres Marias, Nayarit, Mexico. the new species is distinct from related taxa n the adjacent Mexican mainland (M. californicus, M. leibii, and M. carteri), although most closely related to M. carteri as shown by univariate and canonical variates analyses. An...

L. David Mech, Steven T. Knick
1978, Behavioral Biology (23) 521-525
Changes in sleeping distances in 11 pairs of wild wolves (Canis lupus) were studied to determine if they correlated with stages of the breeding cycle. Aerial radio-tracking and observation were the techniques used. Members of most pairs slept less than 1 m apart at least sometime during proestrus and the...
Topographic maps
Theodore D. Steger
1978, Report
A topographic map is a line-and-symbol representation of natural and selected man-made features of a part of the Earth's surface plotted to a definite scale. A distinguishing characteristic of a topographic map is the portrayal of the shape and elevation of the terrain by contour lines....
Climate and reproduction of grizzly bears in Yellowstone National Park
Harold D. Picton
1978, Nature (274) 888-889
Controversy surrounds the conflicts between the requirements of human safety and the preservation of grizzly bears (Ursus arctos horribilis) in western North America. It has been difficult to separate the effect of factors such as the closure of garbage dumps from that of the climate. It has also proved difficult to...
Numerical simulation of dissolved silica in the San Fancisco Bay
David H. Peterson, John F. Festa, T. J. Conomos
1978, Estuarine and Coastal Marine Science (7) 99-116
A two-dimensional (vertical) steady-state numerical model that simulates water circulation and dissolved-silica distributions is applied to northern San Francisco Bay. The model (1) describes the strong influence of river inflow on estuarine circulation and, in turn, on the biologically modulated silica concentration, and (2) shows how rates of silica uptake...
A field evaluation of subsurface and surface runoff. II. Runoff processes
D.H. Pilgrim, D.D. Huff, T.D. Steele
1978, Journal of Hydrology (38) 319-341
Combined use of radioisotope tracer, flow rate, specific conductance and suspended-sediment measurements on a large field plot near Stanford, California, has provided more detailed information on surface and subsurface storm runoff processes than would be possible from any single approach used in isolation. Although the plot was surficially uniform, the...

Seismic amplitude measurements suggest foreshocks have different focal mechanisms than aftershocks
A. Lindh, G. Fuis, C. Mantis
1978, Science (201) 56-59
The ratio of the amplitudes of P and S waves from the foreshocks and aftershocks to three recent California earthquakes show a characteristic change at the time of the main events. As this ratio is extremely sensitive to small changes in the orientation of the fault plane, a small systematic...

Erythrocyte δ-Aminolevulinic Acid Dehydratase Activity in Mallard Ducks: Duration of Inhibition after Lead Shot Dosage
M. P. Dieter, M. T. Finley
1978, Journal of Wildlife Management (42) 621-625
Inhibition of a lead-specific blood enzyme, 8-aminolevulinic acid dehydratase (ALAD), has been utilized to indicate the incidence and degree of lead contamination in canvasback ducks (Aythya valisineria) (Dieter et al. 1976). This variable was found to be more sensitive to lead than previous tests that have been employed with...
Age and sex determination of juvenile band-tailed pigeons
J.A. White, C.E. Braun
1978, Journal of Wildlife Management (42) 564-569
Captive band-tailed pigeons (Columba fasciata) were studied to document progression of molts and plumages from juvenal to adult age. Immature pigeons began the post-juvenal molt at 35 days which continued up to 340 days. The only 3 plumage characters useful for identification and estimation of age were presence of juvenal...
