A Descriptive Model Of The Sweet Corn And Pea Processing Industry Of Southern Minnesota, David P. Brennan

All Graduate Theses, Dissertations, and Other Capstone Projects

This research project was initiated to construct and test a model of the sweet corn and pea processing industry of Minnesota. The model is a composite abstract consisting of several basic theories of general application and several hypotheses which were formulated to consider the unique properties associated with sweet corn and pea processing. These are related to the agricultural and industrial factors which are inseparable parts of sweet corn and pea processing. Testing the model concerned the evaluation of the theories and hypotheses with regard to the real life situation. The basic concepts used in the model were refined and …

Schistosome Dermatitis At Basswood Lake, Minnesota, James A. Zischke, Deloris Palmquist Zischke

Journal of the Minnesota Academy of Science

During the summer of 1965 cases of schistosome dermatitis were reported at the Associated Colleges of the Midwest Wilderness Field, Station on Basswood Lake, Minnesota. Collection and isolation of gastropods from the lake revealed an extremely high incidence of Trichobilharzia ocellata infections in Lymnaea stagnalis. A flock of semi-domestic mallard ducks first introduced al the lake in 1963 are believed to be the principal definitive hosts contributing to the epidemiology of the parasite in the area.

Seasonal Chlorophyll Change In A Leafy Liverwort, Richard L. Anderson, Edward Flaccus

Journal of the Minnesota Academy of Science

It is known that chlorophyll content of plant material varies with the season of the year, though the fact is sometimes lost sight of in studies of particular plant communities. Measurement of seasonal changes has been more often done with higher plants: e.g., Compton and Boynton (1945), Bordeau ( 1959). But Myiata and Hosokowa (1961) studied these changes in epiphytic mosses as correlated with photosynthetic efficiency.

This paper reports on a study made during 1963-1964 of the chlorophyll content of the leafy liverwort, Scapania nemerosa (l.) Dumort, measured at monthly intervals for a period of one year. This plant material …

Spring Dispersal Of Some Leafhoppers And Aphids, A. G. Peterson, J. D. Bates, R. S. Saini

Journal of the Minnesota Academy of Science

Two species of leafhoppers and four species of cereal aphids appear to be transported to Minnesota each spring on strong winds from the south or southwest. The aster leafhopper, Macrosteles fascifrons (Stal); the English grain aphid, Macrosiphum avenae (Fabr.); the apple grain aphid, Rhopalosiphum fitchii (Sand.); and the greenbug, Schizaphis graminum (Rond.), usually arrive in Minnesota during late April or early May. Weather conditions favorable for northward movement of these insects consist of a high pressure area over the eastern states, a low pressure area over the western plains, and the resulting strong, persistent, south wind which is often called …

A Commensal Relationship Between A Foraminifer And A Bivalve Mollusk, Wayne D. Bock, Donald R. Moore

Gulf and Caribbean Research

During June, 1960, the M/V Hermes of the Gulf Coast Research Laboratory made several trawl hauls south of Horn Island, Mississippi. One haul was made June 27 at a depth of 20 m. on sandy mud botton at 30°04’30” N., 88”36’ W., or about 10 nautical miles south of Horn Island. A considerable number of animals, including starfish, hermit crabs and tube worms, were caught in the trawl. Pieces of the parchment-like worm tube of Chaetopterus variopedatus (Renier) were caught in the meshes of the net and were also collected.

A small bivalve mollusk, Notocorbula operculata (Philippi 1848) was found …

A Supplement To The Fauna And Flora Of Horn Island, Mississippi, E. Avery Richmond

Gulf and Caribbean Research

Since the publication of “The Fauna and Flora of Horn Island, Mississippi’’ (Richmond 1962) search for unrecorded species present on this island, or in the waters surrounding it, has been continuing by myself and others. The premise that all of the plants and animals living in a given area can never be located completely is naturally well-founded. However, it seems advisable to continue the search for unlisted species of Horn Island.

Many unrecorded specimens have been collected and it seems proper at this time to make a supplementary list available to the public, particularly those interested in fields of science …

The Function And Use Of Sulphur Dioxide In West Australian Winemaking, D Mann

Journal of the Department of Agriculture, Western Australia, Series 4

THE judicious use of sulphur dioxide is perhaps the most important of the fundamentals of winemaking in a hot climate.

Western Australia's vintage, centred in the Swan Valley just a few miles north-east of Perth, is subjected to some of the highest summer temperatures experienced by a quality wine producing district.

In this environment, it is important to make good use of sulphur dioxide to avoid wine spoilage.

Subterranean Clover Establishment In The Wheatbelt, M L. Poole

Journal of the Department of Agriculture, Western Australia, Series 4

Care and attention to detail will greatly increase the chances of establishing good subterranean clover pastures in the wheatbelt.

PASTURE ESTABLISHMENT usually takes second place to cropping in the wheatbelt, with many farmers "bunging in a bit of clover" and hoping for the best. The worst often transpires, with either patchy stands or complete failure resulting.

Using "cheap" methods of establishment is a short-sighted approach and a waste of energy and resources.

The Status Of Seals In The Gulf Of Mexico With A Record Of Feral Otariid Seals Off The United States Gulf Coast, Gordon Gunter

Gulf and Caribbean Research

The only seal native to the Gulf of Mexico and the Caribbean area is the West Indian seal (family Phocidae). It is tan on the upper surface and a yellowish white underneath. It is now extinct or nearly so. Two seals were reported in Louisiana near the mouth of the Mississippi in January 1966. Photographs of one animal taken from a helicopter showed an otariid seal. In late June a light colored otariid seal began to reside on the buoys of the ship channel leading into Mobile Bay. It stayed there about two and a half weeks. The animal was …

The Role Of Adventitious Reinforcement In Operant Discrimination, Alan Kamil, John W. Davenport

Avian Cognition Papers

Rats were trained in 2 S^D-S^Δ discrimination experiments in which the effects of an S^D-postponement contingency during S^Δ and temporal regularity of S^Δ duration were assessed. Experiment I showed that discrimination is markedly facilitated by the presence of an S^D-postponement contingency of either fixed or variable duration. Experiment II showed that variable-duration S^Δ periods in a noncontingent schedule can also greatly enhance formation of an operant discrimination. These effects were attributed to differences in the probability of adventitious reinforcement of S^Δ behavior by S^D events.

Parasites Of The Inshore Lizardfish, Synodus Foetens, From South Florida, Including A Description Of A New Genus Of Cestoda, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The parasites of the inshore lizardfish, Synodus foetens, were studied from collections taken from an estuarine canal in south Florida between January 1963 and December 1964. A new genus of Cestoda (Bothriocephalidae) has been erected with the proposed name Anantrum. Several larval and adult helminths and a dinoflagellate were studied from monthly samples of Synodus. Incidence of infection, intensity of infection, location of parasites in the host, and associations among parasites are discussed. Extensions of ranges for parasites in S. foetens and parasites heretofore not recorded from S. foetens are noted.

Notes On Spotted Skunks (Genus Spilogale) From Western Mexico, Hugh H. Genoways, J. Knox Jones Jr.

University of Nebraska State Museum: Mammalogy Papers

Specimens of spotted skunks acquired from western Mexico by the Museum of Natural History at the University of Kansas in the past two decades add substantially to the knowledge of the species occurring in that region. Two specimens of the rare Spilogale pygmaea (one from Sinaloa and one from Oaxaca) are reported for the first time. Two subspecies of pygmy spotted skunk are recognized - S. p. pygmaea Thomas with type locality at Rosario, Sinaloa, and S. p. australis Hall with type locality at Acapulco, Guerrero.

The large spotted skunk, Spilogalepusorius, varies clinally in size form north (larger) to …
