Fall food habits of ducks near Santee Refuge, South Carolina
During the 1961 waterfowl hunting season, 360 stomachs of 10 duck species were collected from hunters near the Santee National Wildlife Refuge, Lake Marion, South Carolina. Based on percentage of total volume, 20 of the most important foods are listed. The six most important duck species in the kill were: mallard (Anas platyrhynchos), wood duck (Aix sponsa), widgeon (Mareca americam), pintail (Ana

Virus diseases of the salmonidae in the western United States. III. Immunopathological aspects
The immune response among fish, from a phylogenetic standpoint, presents a progressive pattern of increasing development. The cyclostomes have been shown to have only feeble immunologic responsiveness. One of their number, the hagfish, appeared to be totally lacking in the ability to actively acquire antibodies.Among the elasmobranchs, the sharks have received the most study immunologically. This

The distribution and abundance of planktonic diatoms in Lake Superior
The principal diatoms collected at 14 stations in Lake Superior were Cyclotella "glomerata-stelligera" [= C. glomerata and C. stelligera combined], Cyclotella "ocellata-kutzingiana", Fragilaria crotonensis, and Rhizosolenia eriensis. Concentrations were heaviest in the Apostle Islands region (up to 2,160 per ml) and lightest northwest of the Keweenaw Peninsula (68 to 78 per ml). Species compositio

Experimental control of sea lampreys with electricity on the south shore of Lake Superior, 1953-60
Experimental control of the sea lamprey, Petromyzon marinus, with electric barriers was begun in Lake Superior in 1953. Electrical devices were the most practical and promising method of control then available. Installed below spawning grounds in streams and rivers tributary to Lake Superior, these barriers were designed to prevent the sexually mature sea lampreys from reproducing.
The catch of se

Relative toxicities of similar formulations of pyrethrum and rotenone to fish and immature stoneflies
The insecticidal properties of rotenone and pyrethrum have been known for many years. Both toxicants have long histories of extensive use for control of a variety of insect pests. Rotenone has been also employed as a management tool by fishery biologists to rehabilitate fishing waters, and its toxicity to fish in a number of ecological situations is well established. Pyrethrum's toxicity to fish i
