Effect of certain anesthetic agents on mallard ducks Effect of certain anesthetic agents on mallard ducks
Four anesthetic agents used in human or veterinary medicine and 3 experimental anesthetic preparations were evaluated for effectiveness in inducing narcosis when administered orally to game-farm mallard ducks (Anas platyrhynchos).Tribromoethanol was the only compound to satisfy criteria of initial tests. Mean duration of the induction, immobilization, and recovery periods was 2.4 minutes...

Vegetation of prairie potholes, North Dakota, in relation to quality of water and other environmental factors Vegetation of prairie potholes, North Dakota, in relation to quality of water and other environmental factors
Measurements of specific conductance provide an adequate indication of the average salinity of surface waters in natural ponds and lakes of the northern .prairie region. Yearly and seasonal variations in specific conductance were much greater in brackish and subsaline wetlands than in fresh-water areas. The principal vegetational types. Land-use practices of varying brackish to saline...

Production and standing crop of Hexagenia (Ephemeroptera) in a large reservoir Production and standing crop of Hexagenia (Ephemeroptera) in a large reservoir
Population dynamics of the mayflies, Hexagenia limbata (Serville) and Hexagenia bilineata (Say), were studied in Lewis and Clark Lake from 1962 to 1969. Nymphs that hatched in June and July emerged as adults in 13-14 months (titled 1-year cycle) and nymphs hatched in late August or September emerged in 22 months (titled 2-year cycle). Although an estimated 79% of the newborn nymphs begin...

Hatchability tests with eggs from captive wood ducks Hatchability tests with eggs from captive wood ducks
The effect of diet and artificial incubation on fertility and hatchability of wood duck (Aix sponsa) eggs and survival of young was measured. Hatchability of eggs from hens fed a diet containing 37 percent protein was increased significantly (P

Waterfowl nesting on interstate highway right-of-way in North Dakota Waterfowl nesting on interstate highway right-of-way in North Dakota
We studied 630 acres of roadside along 23 miles of Interstate 94 in Stutsman County, North Dakota, to assess wildlife values of highway rights-of-way. We found 422 duck nests that had an overall success of 57 percent in 1968, 1969, and 1970. Mammalian predators were responsible for 85 percent of the destroyed nests. To test the effect of mowing on duck nest initiation and success...

A device for monitoring radio-marked animals A device for monitoring radio-marked animals
A simple, portable, and economical recording system consisting of a receiver, signal conditioner, recorder, and power source is described. The system was designed to monitor the signal strength from a radio-marked animal at a particular location. Information is stored on recorder chart paper. Radio-marked ducks have been successfully monitored at nest sites, potholes, and other locations...
