I.B. Tarshis
1968, Annals of the Entomological Society of America (61) 960-961
A technique is described for using strips of gauze to collect large numbers of larvae of Cnephia dacotensis (Dyar & Shannon), Simulium decorum (Walker), S. venustuni Say, S. vcrecundum Stone & Jamnback, and S. vittatum Zetterstedt from various water habitats....
Anemia and mechanism of erythrocyte destruction in ducks with acute Leucocytozoon infections
R. M. Kocan
1968, Journal of Protozoology (15) 455-462
In the anemia which accompanies infection by Leucocytozoon simondi in Pekin ducks there was a far greater loss of erythrocytes than could be accounted for as a result of direct physical rupture by the parasite. Erythrocyte loss began at the same time the 1st parasites appeared in the blood and was severest...
Lack of association among duck broodmates during migration and wintering
R. K. Martinson, A.S. Hawkins
1968, The Auk (85) 684-686
Male (Lensink, 1964: 19) and female ducks tend to return to the area where they last bred or were raised (Sowles, 1955). Band recovery data show a similar tendency for ducks to return to wintering areas (Stewart et al., 1958; Martinson, 1966). Wintering British Columbia Mallard (Anas platyrhynchos) populations may be...
Singing behavior of the Swainson's warbler
B. Meanley
1968, The Wilson Bulletin (80) 72-77
Studies of the singing behavior of the Swainson?s Warbler were conducted mainly near Macon, Bibb County, Georgia, and in the Dismal Swamp, Nansemond County, Virginia, during the springs of 1965 and 1966. Singing behavior on the ground and in trees is discussed. Swainson?s Warblers sing vigorously from the time they...
Blood parasites in North American waterfowl
C. M. Herman
1968, Transactions of the North American Wildlife and Natural Resources Conference (33) 348-359
One thing seems to stand out in the overall knowledge we have of the blood parasites of waterfowl, as previously noted by Herman and Wehr, (1954): the greatest potential of losses is in the younger age groups, usually those birds 5-10 weeks old. In Leucocytozoon infections, death occurs as early...

Chlorinated hydrocarbons and eggshell changes in raptorial and fish-eating birds
J.J. Hickey, D. W. Anderson
1968, Science (162) 271-273
Catastrophic declines of three raptorial species in the United States have been accompanied by decreases in eggshell thickness that began in 1947, have amounted to 19 percent or more, and were identical to phenomena reported in Britain. In 1967, shell thickness in herring gull eggs from five states decreased...

The concept of home range was expressed by Seton (1909) in the term 'home region,' which Burr (1940, 1943) clarified with a definition of home range and exemplified in a definitive study of Peromyscus in the field. Burt pointed out the ever-changing characteristics of home-range area and the consequent...

Uptake and distribution of Zn65 in the coho salmon egg (Oncorhynchus kisutch)
Gary Wedemeyer
1968, Comparative Biochemistry and Physiology (26) 279
1. Zinc uptake and distribution in the developing coho salmon egg was measured using radioisotope tracer techniques.2. The uptake was affected by pH, temperature, Cu2+, 2,4-fluorodinitrobenzene and the azo dye, malachite green; but not by azide ion or 2,4-dinitrophenol.3. About 70 per cent of the total accumulated zinc was bound,...

Seismic seiches from the March 1964 Alaska earthquake
Arthur McGarr, Robert C. Vorhis
1968, Professional Paper 544-E
Seismic seiches caused by the Alaska earthquake of March 27, 1964, were recorded at more than 850 surface-water gaging stations in North America and at 4 in Australia. In the United States, including Alaska and Hawaii, 763 of 6,435 gages registered seiches. Nearly all the seismic seiches were recorded at...

Effects of the Alaska earthquake of March 27, 1964, on shore processes and beach morphology
Kirk W. Stanley
1968, Professional Paper 543-J
Some 10,000 miles of shoreline in south-central Alaska was affected by the subsidence or uplift associated with the great Alaska earthquake of March 27, 1964. The changes in shoreline processes and beach morphology that were suddenly initiated by the earthquake were similar to those ordinarily caused by gradual changes in...
