Effects on fish and wildlife of chemical treatments of large areas
Summary: The history of field investigations of the effects of DDT on wildlife is reviewed briefly, from the initial studies in 1945 through the more recent studies of the effects of the large-scale programs for spruce-budworm control and gypsy-moth eradication. DDT dosages and procedures that are recommended for protection of wildlife are reviewed. Effects of aldrin, heptachlor, and toxaphene

Notes on Bachman's sparrow in Central Louisiana
Notes on the ecology of Bachman’s Sparrow (Aimophila aestivalis) were obtained during a study of birds in relation to the direct or artificial seeding of Longleaf Pine (Pinus palustris) and Loblolly Pine (P. taeda) in central Louisiana from 1955 to 1957. Stoddard (in Burleigh, “Georgia Birds,” pp. 667-668, 1958) has presented an account of the ecology of this species in the pine woods of southern

Tree ducks arrive in the rice country as the rice is planted in the spring and usually depart following fall harvest. A fe

Fish mycobacteriosis (Tuberculosis)
The etiologic agent for the bacterial disease, "fish tuberculosis" (more correctly "mycobacteriosis"), was first observed in carp in 189& from a pond in France. Subsequently similar agents have been isolated from or observed in fish in fresh water, salt water, and brackish water, in fish in aquaria, hatcheries, and natural habitat~ (wild populations of fish). The disease has been recognized as an

Plasmoptysis and gelatin of erythrocytes in coagulation of blood of freshwater bony fishes
1. A clot-like material which results from very rapid plasmoptysis and hydrophyllic swelling of karyoplasm of erythrocytes from freshwater fish was reported. This attribute was found to a lesser degree in erythrocytes from an amphibian, but it was almost lacking in those of an aquatic reptile.2. Rapid clotting of fish blood with the usual clinical methods was confirmed in this work. Fish blood clo
