Coccidia of whooping cranes
Donald J. Forrester, J. W. Carpenter, D.R. Blankinship
1978, Journal of Wildlife Diseases (14) 24-27
Coccidial oocysts were observed in 6 of 19 fecal samples from free-ranging whooping cranes (Grus americana) and 4 of 16 samples from captive whooping cranes. Eimeria gruis occurred in four free-ranging whooping cranes and E. reichenowi in two free-ranging and two captive whooping cranes. Fecal samples from two captive cranes contained oocysts of lsospora lacazei which...
Biochemical identification of mallard-black duck hybrids through a breeding program and in nature
R.P. Morgan II, D. W. Meritt, S. B. Block, M. Cole
1978, Transactions of the Northeast Section of the Wildlife Society, Annual Fish and Wildlife Conference (35) 225-236
From 1974 to 1976, a breeding program was used to produce black duck-mallard hybrids for the evaluation of inheritance patterns of serum proteins and esterases. In addition to the initial crosses, a series of matings in 1975 and 1976 were designed to evaluate inheritance patterns in hybrid matings with either...

Seasonal trends in summer diet of the lapland longspur near Barrow Alaska USA
T. W. Custer, F.A. Pitelka
1978, The Condor (80) 295-301
Contents of lapland longspur [Calcarius lapponicus] stomachs and esophagi were sampled near Barrow, Alaska [USA], from May-Aug. in 1969, 1971, 1972 and 1973. Data from stomach contents were corrected for differential digestion of prey items. Longspurs shifted seasonally from larval to adult arthropods and back to larvae, responding to changes...
Movements of walleyes tagged in eastern Lake Erie
David R. Wolfert, Harry D. Van Meter
1978, New York Fish and Game Journal (25) 16-22
In May, October and November of 1968, 2,456 walleyes of various ages were captured, tagged and released in eastern Lake Erie to determine seasonal movement of walleyes in that basin and the degree to which they intermingled with fish of the central and western basins. From 1968 to 1971, 275...
Feeding habitat use by colonially-breeding herons, egrets, and ibises in North Carolina
Thomas W. Custer, Ronald G. Osborn
1978, The Auk (95) 733-743
Nine species of herons, egrets, and ibises were followed by airplane from a nesting colony near Beaufort, North Carolina to their feeding sites. Except for Cattle Egrets, which flew exclusively to fields and dumps, the birds flew mainly to saltmarsh habitat. The selection of feeding habitats by Great Egrets and...

Transient creep and semibrittle behavior of crystalline rocks
N.L. Carter, S. H. Kirby
1978, Pure and Applied Geophysics PAGEOPH (116) 807-839
We review transient creep and semibrittle behavior of crystalline solids. The results are expected to be pertinent to crystalline rocks undergoing deformation in the depth range 5 to 20 km, corresponding to depths of focus of many major earthquakes. Transient creep data for crystalline rocks at elevated temperatures are analyzed...
Reproduction of raccoons (Procyon lotor) in North Dakota
E.K. Fritzell
1978, American Midland Naturalist (100) 253-256
Necropsies and observations of captive and radio-equipped individuals provided reproductive data from a raccoon population in the northern prairies. The mean parturition date of adult females was 8 May and the mean litter size was 4.8. Only two of the 14 yearling females examined prior to 1 July were pregnant;...
Habitat use by prairie raccoons during the waterfowl breeding season
E.K. Fritzell
1978, Journal of Wildlife Management (42) 118-127
Mobility and habitat use of raccoons (Procyon lotor) in an intensively farmed area of the prairie pothole region were studied during the waterfowl breeding seasons (April-July) of 1973-75. Over 5700 locations of 30 raccoons were analyzed. Movement patterns varied with sex, age, and reproductive status. Adult males moved regularly throughout...
Aspects of raccoon (Procyon lotor) social organization
E.K. Fritzell
1978, Canadian Journal of Zoology (56) 260-271
Spatial and temporal relationships among members of a raccoon (Procyon lotor) population were studied during spring and summer in east-central North Dakota during 1973–1975. Radio telemetry was used to locate 48 raccoons 6443 times. Livetrapping results and other observations suggested that most raccoons in the area were radio equipped; densities...
Evaluating call-count procedures for measuring local mourning dove populations
M.J. Armbruster, T.S. Baskett, W.R. Goforth, K.C. Sadler
1978, Transactions of the Missouri Academy of Science (12) 75-90
Seventy-nine mourning dove call-count runs were made on a 32-km route in Osage County, Missouri, May 1-August 31, 1971 and 1972. Circular study areas, each 61 ha, surrounding stop numbers 4 and 5, were delineated for intensive nest searches and population estimates. Tallies of cooing male doves along the entire...

Wetland classification in the United States
L.M. Cowardin
1978, Journal of Forestry (76) 666-668
Wetland is part of a continuum of land types between deep water and dryland. Only one wetland classification was available for the United States prior to preparation of the new system described here, but numerous regional and special-purpose classifications are in use. The new classification is hierarchical, progressing from five...
Fecundity of the bloater (Coregonus hoyi) in Lake Michigan
Lee Emery, Edward H. Brown Jr.
1978, Transactions of the American Fisheries Society (107) 785-789
Using ovaries sampled seasonally from Lake Michigan bloaters in 1968-1969, we determined that one complement or modal group of eggs is produced each year and spawned mainly during January, February, and March. Fecundities estimated for 65 fish taken in October ranged from 3,230 eggs in one medium-size bloater (241 mm...
Changes in submerged aquatic macrophyte populations at the head of Chesapeake Bay, 1958-1975
S. Bayley, Vernon D. Stotts, P. F. Springer, J. Steenis
1978, Estuaries (1) 171-182
Submerged aquatic plant populations in the Susquehanna Flats of the Chesapeake Bay were followed for 18 years. An exotic species, eurasian water milfoil, Myriophyllum spicatum, increased dramatically from 1958 to 1962; at the same time the dominant native species declined. After 1962, milfoil populations declined and the native rooted aquatics...
Waterfowl nesting on small man-made islands in prairie wetlands
R.F. Johnson Jr., R.O. Woodward, L.M. Kirsch
1978, Wildlife Society Bulletin (6) 240-243
Small islands constructed in prairie wetlands were attractive nesting sites for mallards (Anas platyrhynchos) and Canada geese (Branta canadensis). Nest densities of mallards on islands averaged 135 per ha compared to 0.03 per ha on adjacent upland habitats. Construction time averaged 2 hours per island and cost $50. No maintenance...

Formation of lunar basin rings
C. A. Hodges, D.E. Wilhelms
1978, Icarus (34) 294-323
The origin of the multiple concentric rings that characterize lunar impact basins, and the probable depth and diameter of the transient crater have been widely debated. As an alternative to prevailing “megaterrace” hypotheses, we propose that the outer scarps or mountain rings that delineate the topographic rims of basins—the Cordilleran...
Applications of the VLF induction method for studying some volcanic processes of Kilauea volcano, Hawaii
C.J. Zablocki
1978, Journal of Volcanology and Geothermal Research (3) 155-195
The very low-frequency (VLF) induction method has found exceptional utility in studying various volcanic processes of Kilauea volcano, Hawaii because: (1) significant anomalies result exclusively from ionically conductive magma or still-hot intrusions (> 800??C) and the attendant electrolytically conductive hot groundwater; (2) basalt flows forming the bulk of Kilauea have...
Friction of rocks
J. Byerlee
1978, Pure and Applied Geophysics PAGEOPH (116) 615-626
Experimental results in the published literature show that at low normal stress the shear stress required to slide one rock over another varies widely between experiments. This is because at low stress rock friction is strongly dependent on surface roughness. At high normal stress that effect is diminished and the...
Distinctive sedimentary features of cold-climate eolian deposits, North Park, Colorado
Thomas S. Ahlbrandt, S. Andrews
1978, Palaeogeography, Palaeoclimatology, Palaeoecology (25) 327-351
Cold-climate eolianites contain diagnostic sedimentary features that contrast with the sedimentary features of warm-climate eolianites. Distinctive tensional, compressional, and dissipation sedimentary structures related to freezing, thawing and snow melting characterize eolian dune-sand deposits in North Park, Colorado. The North Park dunes have few of the characteristics considered to be diagnostic...
