1975, Book chapter, Mineral materials modeling A state-of-the-art review
The least exacting demand that can be made of any model is that it serves as a device whereby we can predict actual physical happenings. Another demand which could be made is that the physical happenings predicted be in some way relevant to man, either by allowing him to anticipate...

A disease of freshwater fishes caused by Tetrahymena corlissi Thompson, 1955, and a key for identification of holotrich ciliates of freshwater fishes
G. L. Hoffman, M. Landolt, J.E. Camper, D.W. Coats, J.L. Stookey, J.D. Burek
1975, Journal of Parasitology (61) 217-223
Tetrahymena corlissi, a free-living protozoan, apparently caused the death of large numbers of guppies (Poecilia reticulatus) and occasionally other fishes, in aquaria and hatcheries at several locations. Apparently the disease occurs when the fish and protozoan populations are both at a high level of density. The signs include white spots...

The carcass of a subadult female Delphinus was placed in a hyperbaric chamber and subjected to two simulated dives each equivalent to 69.7 m. In one dive the thorax was in its natural state, and in the other 100 ml of water had been injected into each pleural cavity. Various morphometric...

Thin-section electron microscopy of mature Myxosoma cerebralis (Myxosporidea) spores
P.D. Lunger, B.L. Rhoads, K. Wolf, M.E. Markiw
1975, Journal of Parasitology (61) 476-480
The morphology of purified, mature Myxosoma cerebralis spores was examined by thin-section electron microscopy. Surface architecture corresponded closely to that described in an earlier scanning electron microscopy study of this organism (Lom and Hoffman, 1971). A uniformly thick spore wall is composed of finely granular, electron-lucent material. Intrawall "valvoplasm" at...
A spring aerial census of red foxes in North Dakota

1975, Journal of Wildlife Management (39) 30-39
Systematic aerial searches were flown on transects to locate adult red foxes (Vulpes vulpes), pups, and rearing dens on 559.4 km2 (six townships) in eastern North Dakota during mid-May and mid-June each year from 1969 through 1973 and during mid-April 1969 and early May 1970. The combined sightings of foxes...
Some nutritional aspects of reproduction in prairie nesting pintails
Gary L. Krapu, G.A. Swanson
1975, Journal of Wildlife Management (39) 156-162
The nutritional significance of invertebrate foods in the diet of breeding hen waterfowl during the period of egg formation is discussed. Proximate, elemental, and amino acid analyses of the principal foods consumed by hen pintails (Anas acut) during the nesting season indicate the animal foods selected are rich sources of...
Duck plague in free-flying waterfowl observed during the Lake Andes epizootic

1975, Wildlife Disease Conference (67) 1-16
The first major epizootic of duck plague in free-flying waterfowl occurred at Lake Andes, South Dakota, in January and February, 1973. Duck plague was diagnosed in black ducks, mallards, pintail-mallard hybrids, redheads, common mergansers, common golden eyes, canvasbacks, American widgeon, wood ducks, and Canada geese, indicating the general susceptibility of...

Sandrewia, n. gen., a problematical plant from the Lower Permian of Texas and Kansas
S.H. Mamay

Sandrewia, n. gen., monotypified by S. texana, n. sp., is a plant from Lower Permian beds of north-central Texas and east-central Kansas. It is characterized by stout axes with spirally disposed, laxly inserted, petiolate leaves; the laminae are broadly flabelliform with coarse, open venation....
Death feigning by ducks in response to predation by red foxes (Vulpes fulva)
Alan B. Sargeant, L. E. Eberhardt
1975, American Midland Naturalist (94) 108-119
Predation by captive red foxes (Vulpes fulva) on approximately 50 ducks comprised of five species was observed in tests conducted at the Northern Prairie Wildlife Research Center, Jamestown, North Dakota. Most ducks were attacked from a rear or lateral position and seized in the cervical or thoracic region. All birds...
