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;...
Myxosoma cerebralis: Fluorescent antibody techniques for antigen recognition
M.E. Markiw, K. Wolf
1978, Journal of the Fisheries Research Board of Canada (35) 828-832
Rabbits were immunized with antigens extracted from mature spores or prespore stages of Myxosoma cerebralis, and the resulting antisera and their globulins were used in direct and indirect fluorescent antibody techniques. Both kinds of antisera reacted with homologous spores and with stages of the organism that precede spores. When tested for...
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...
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...
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...

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...
Evaluation of an aerial survey of Pacific walruses
J. A. Estes, James R. Gilbert
1978, Journal of the Fisheries Research Board of Canada (35) 1130-1140
An aerial survey of Pacific walruses (Odobenus rosmarus divergens) was evaluated to determine the reliability of estimates of population abundance. The probability of detecting groups of walruses on the pack ice remained uniform to at least 0.93 km from the flight line, whereas the probability of detection decreased significantly beyond 0.23 km...
Sea otter predation and community organization in the western Aleutian Island, Alaska
J. E. Estes, N. S. Smith, J. F. Palmisano
1978, Ecology (59) 822-833
Predation by the sea otter (Enhydra lutris) limits epibenthic invertebrates, especially sea urchins (Strongylocentrotus polyacanthus), in turn allowing a luxuriant development of the macroalgal canopy. Where sea otters are abundant, sea urchins are small and scarce in shallow water, and the association of fleshy macroalgae apparently is regulated by competition....
Malic acid accumulation in roots in response to flooding: Evidence contrary to its role as an alternative to ethanol
Jon E. Keeley
1978, Journal of Experimental Botany (29) 1345-1349
Across a time course of flooding the malic acid content in roots of the swamp tree Nyssa sylvatica var. biflora increased 5-fold from 1 week to 1 month of flooding and remained at that level through a full year of flooding. Alcoholic fermentation rates accelerated within the first month of flooding but dropped to...
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...
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...
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...
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...

Quality of water in Pascagoula and Escatawpa Rivers, Jackson County, Mississippi
Gene A. Bednar
1978, Open-File Report 78-913
The chemical and physical properties and the range of concentrations of most constituents in water in the Pascagoula and Escatawpa Rivers during the period May 17-19, 1977, varied rapidly between high and low tides, primarily as the result of interactions of freshwater inflow with highly mineralized Gulf waters. The water...
Selected uranium and uranium-thorium occurrences in New Hampshire
Wallace A. Bothner
1978, Open-File Report 78-482
Secondary uranium mineralization occurs in a northwest-trending fracture zone in the Devonian Concord Granite in recent rock cuts along Interstate Highway 89 near New London, New Hampshire. A detailed plane table map of this occurrence was prepared. Traverses using total gamma ray scintillometers throughout the pluton of Concord Granite identified...
