DDE thins eggshells and lowers reproductive success of captive black ducks
J. R. Longcore, F. B. Samson, T.W. Whittendale Jr.
1971, Bulletin of Environmental Contamination and Toxicology (6) 485-490
Eggs of captive black ducks fed diets containing DDE at 10 and 30 ppm (dry weight) experienced significant shell thinning and an increase in shell cracking when compared to eggs of untreated black ducks. Eggshells from dosed ducks were: 18-24 percent thinner at the equator than shells from undosed...
The occurrence and significance of polychlorinated biphenyls in the environment
E. H. Dustman, L.F. Stickel, L. J. Blus, W. L. Reichel, Stanley N. Wiemeyer
1971, Transactions of the North American Wildlife and Natural Resources Conference (36) 118-131
SUMMARY: Polychlorinated biphenyls constitute a group of chlorine-bearing compounds of industrial origin that have permeated the natural environment throughout the world. Their chemical structure resembles that of some of the organochlorine pesticides. They are troublesome interferences in gas chromatographic analysis of these...
Distribution of the fiddler crab (Uca minax) in relation to marsh plants within a Virginia estuary
J.A. Kerwin
1971, Chesapeake Science (12) 180-183
The distribution and abundance of the red-jointed fiddler crab, Uca minax, was related to the distribution of marsh plants within a Virginia estuary. The crab was found in association with 15 species of marsh phanerogams, occurring with five plant species more than 20 percent of the time. These plants were...

Monitoring pesticides in wildlife
E. H. Dustman, W.E. Martin, R.G. Heath, W. L. Reichel
1971, Pesticides Monitoring Journal (5) 50-52
Early in the development of the wildlife monitoring program, certain criteria were recognized as being important in the selection of species of wild animals suitable for pesticide monitoring purposes. Ideally, the forms selected should be geographically well distributed, and they should be reasonably abundant and readily available for sampling....
Some patterns of woodcock activities on Maine summer fields
W.B. Krohn
1971, The Wilson Bulletin (83) 396-407
Certain aspects of woodcock usage of summer fields were studied in Maine. Findings were as follows: ....1. On two study fields in 1968, numbers of woodcock first began spending nights in the fields during the second week of June. During 1968 and 1969, the number of birds flushed from the...

1971, The Auk (88) 676-676
The correct date of publication of numbers in the well-known North American Fauna series, begun in 1889, was printed on the cover of each issue through No. 48. After that time dates of publication that appear on the covers are either incomplete or incorrect. For taxonomic purposes, for developing a...
Population ecology of the great blue heron with special reference to western Oregon
Charles J. Henny, M.R. Bethers
1971, Canadian Field-Naturalist (85) 205-209
Great Blue Heron (Ardea herodias) begin nesting in western Oregon about 1 month earlier than reported from the Philadelphia region and about 2 months earlier than reported from Southern Alberta. The number of young fledged per nesting pair in Oregon was 2.04 in 1970 which was nearly identical to the...
Synecology of a Virginia salt marsh
J.A. Kerwin, R. Pedigo
1971, Chesapeake Science (12) 125-130
In the spring and summer of 1964 a salt marsh in Gloucester County, Virginia, was analyzed using random quadrat sampling. Synthetic treatments were employed to evaluate data and were correlated with observed differences in elevation. Floristic data indicate the Virginia salt marshes show closer similarity to marshes north of Chesapeake...
Blood parasites of wood ducks
C. M. Herman, J. O. Knisley Jr., G. D. Knipling
1971, Journal of Wildlife Management (35) 119-122
Examination of blood films from wood ducks (Aix sponsa) from several northeastern states revealed Haemoproteus, Leucocytozoon, Plasmodium and a typanosome. Haemoproteus occurred in all areas sampled and birds of the year from Massachusetts demonstrated the highest incidence during the last 2 weeks in August. Leucocytozoon was most prevalent in more...

1971, Annals of the Entomological Society of America (64) 1194-1195
In studies relating to the biology and ecology of black flies, live larvae of at least 70 species of Simuliidae have been collected from their natural breeding sites and transported in containers with nonagitated water for short distances to the laboratory. One of us (Tarshis 1966) found, however, that even...

Chlorinated hydrocarbons in the marine environment. A report prepared by the Panel on Monitoring Persistent Pesticides in the Marine Environment of the Committee on Oceanography
Panel on Monitoring Persistent Pesticides in the Marine Environment, E.D. Goldberg, P. Butler, P. Meier, D. Menzel, G. Paulik, R. Risebrough, L.F. Stickel

SUMMARY AND RECOMMENDATIONS : The oceans are an ultimate accumulation site for the persistent chlorinated hydrocarbons. As much as 25 percent of the DDT compounds produced to date may have been transferred to the sea. The amount of DDT compounds in the marine biota is estimated to...
Status of correlation of Quaternary stratigraphic units in the western conterminous United States
P. W. Birkeland, D. R. Crandell, G.M. Richmond
1971, Quaternary Research (1) 208-227
Deposits of Quaternary age from the Rocky Mountains to the Pacific Coast in the western conterminous United States represent a great variety of environments. The deposits include those of continental and alpine glaciers, glacial meltwater streams, nonglacial streams, pluvial lakes, marine environments, eolian environments, and masswasting environments. On two charts...
Aircraft measurements of microwave emission from Arctic Sea ice
T. Wilheit, W. Nordberg, J. Blinn, W. Campbell, A. Edgerton
1971, Remote Sensing of Environment (2) 129-139
Measurements of the microwave emission from Arctic Sea ice were made with aircraft at 8 wavelengths ranging from 0.510 to 2.81 cm. The expected contrast in emissivities between ice and water was observed at all wavelengths. Distributions of sea ice and open water were mapped from altitudes up to 11...
The sea sled - A device for measuring bottom profiles in the surf zone
E. Reimnitz, D.A. Ross
1971, Marine Geology (11) M27-M32
The Sea Sled is a simple, easily constructed device for obtaining relatively accurate and quick bottom profiles in the surf zone. The onshore — offshore motion associated with the passage of waves propels the sled on both its seaward traverse and the shoreward...
Effects of irrigation on streamflow in the Central Sand Plain of Wisconsin
E.P. Weeks, H.G. Stangland
1971, Open-File Report 70-362
Development of ground water for irrigation affects streamflow and water levels in the sand-plain area of central Wisconsin. Additional irrigation development may reduce opportunities for water-based recreation by degrading the streams as trout habitat and by lowering lake levels. This study was made to inventory present development of irrigation in...
