Monoculture, Polyculture, And Polyvariety In Tropical Forest Swidden Cultivation, Raymond B. Hames

Department of Anthropology: Faculty Publications

A number of researchers have suggested that polyculture is characteristic of native tropical forest swiddens and have adduced theory from community ecology to account for its adaptiveness. Ye’kwana and Yąnomamö swidden cultivation is examined, and it is shown that polyculture is not practiced to any significant degree. Instead, the concept of polyvariety is introduced along with a number of other cultivation practices that more simply account for the adaptiveness of Ye’kwana and Yąnomamö gardening. In addition, comparative data from other parts of the tropical world indicate that polyculture is no more common than monoculture and recent advances in ecological research …

1983 Annual Report

Southeast Research and Extension Center: Reports and Administration

1983 was another interesting year for the staff of our unit, our clientele and for those of us involved in administration.

On the agricultural front, the fall and winter of 1982 and the spring of 1983 were very wet; while July, August, and September were very, very hot and dry.

The PIK (Payment In Kind) added a dimension of uncertainty, but did have a positive effect on prices. Over 50% of the cropland was retired in some of the counties in southeast Nebraska.

Unfavorable economic conditions strained the financial stability of many farmers and businesses in our district. Unemployment climbed …

The Foraging Behavior Of Lacewing Larvae On Vertical Rods, Alan B. Bond

Alan Bond Publications

The foraging behavior of lacewing larvae (Chrysopa carnea Stephens, Chrysopidae, Neuroptera) on vertical lucite rods was observed under a variety of experimental conditions to investigate the decision processes responsible for the distribution of foraging effort. Food deprivation increased the duration of searching on all parts of the rod, whereas contact with prey at the rod tip induced only a local enhancement of searching activity. Searching at the rod tip did not decline with repeated trials on the same rod, but the duration of searching on the rest of the rod was reduced, evidently reflecting recognition and avoidance of previously-searched …

Cranes Of The World: 6. Aviculture And Hybridization, Paul A. Johnsgard

Cranes of the World by Paul A. Johnsgard

The keeping of cranes in captivity, either as pets or as animals to be fattened for the pot, is evidently a very old practice. Captive cranes are depicted on the walls of the Temple of Deir-el-Barari of the Nile Valley, where cranes are shown walking in stately fashion between slaves. Each crane's bill is tied down close to its neck, which would upset its balance and thus prevent it from flying away (Whymper, 1909). Armstrong (1979) noted that cranes were apparently domesticated in ancient Greece, and that Plutarch (c. A.D. 46-c. A.D. 120) mentions the nesting of tame cranes, presumably …

Cranes Of The World: 7. Endangered Species And Conservation, Paul A. Johnsgard

Cranes of the World by Paul A. Johnsgard

Few families of birds, other than some associated with small island archipelagos, have such a large proportion of their species in danger of extinction as does the crane family. Of the 14 extant species of cranes, King (1979) regards two full species (whooping crane and Siberian crane) as endangered, three more (Japanese, hooded, and white-naped) as vulnerable, and the black-necked crane as of indeterminate status. Additionally, one race (the Mississippi) of the sandhill crane is classified as endangered, and the Cuban race is regarded as rare and local. Thus, more than a third of the world's crane species are currently …

"Dried Fat" For Growing-Finishing Swine, K. E. Keaschall, B. D. Moser, E. R. Peo, Jr., A. J. Lewis, T. D. Crenshaw, Win Butler

Department of Animal Science: Faculty Publications

Three trials were conducted to determine the effect of "dried fat" (fats absorbed on carriers) in diets for growing-finishing swine. In trial I pigs receiving diets containing 5% added fat gained faster (.74 vs .71 kg/d), consumed less feed (1.87 vs 2.43 kg/d) and had a better feed efficiency (2.52 vs 2.88) than pigs fed diets without added fat (all P<.01). Pigs given the "dried fat" treatments gained faster (P<.01) and more efficiency (P<.01) than pigs fed the nonfat carrier counterpart. "Dried fats" containing whey plus fat and wheat bran plus fat produced similar performance to that observed with pigs fed a conventional tallow diet.

Human Adaptations In The Andes: A Look At Nutrition And Brain Function With Respect To Coca And High Altitude Physiological Adaptations, Barrett P. Brenton

Nebraska Anthropologist

Throughout the span of human evolution the brain has allowed itself to be controlled by nutritional intake. This correlation between nutrition and the brain has led me to believe that the human brain has allowed itself to be manipulated and controlled by an individual's dietary intake in order to successfully adapt to the environment. In looking at the indigenous peoples of the South American Andes, I found surprising parallels between human physiological adaptations to high altitude hypoxia and cold stress and the correlating control of neurotransmitters to the brain by dietary intake.

In a study of this type it becomes …

Manioc And Fish: A "Methiononian" Compromise In Amazonia?, Tom Langdon

Nebraska Anthropologist

Protein as a limiting factor in Amazonian diet has met with considerable discussion and argument (e.g., Beckerman 1979; Chagnon and Hames 1979; Johnson 1982; Gross 1975, 1982; Spath 1978, 1981; Werner et al. 1979). The intent of this paper is to continue the discussion of protein as a limiting factor in Amazonia with respect to two dietary staples, manioc and fish. More specifically, does bitter manioc become a factor in determining aquatic resource utilization in Amazonia?

Expression Of A Streptococcus Mutans Glucosyltransferase Gene In Escherichia Coli, James P. Robeson, Raul G. Barletta, Roy Curtiss Iii

School of Veterinary and Biomedical Sciences: Faculty Publications

Chromosomal DNA from Streptococcus mutans strain UAB90 (serotype c) was cloned into Escherichia coli K-12. The clone bank was screened for any sucrosehydrolyzing activity by selection for growth on raffinose in the presence of isopropyl- β-D-thiogalactoside. A clone expressing an S. mutans glucosyltransferase was identified. The S. mutans DNA encoding this enzyme is a 1.73-kilobase fragment cloned into the HindIII site of plasmid pBR322. We designated the gene gtfA. The plasmid-encoded gtfA enzyme, a 55,000-molecular-weight protein, is synthesized at 40% the level of pBR322-encoded β-lactamase in E. coli minicells. Using sucrose as substrate, the gtfA enzyme catalyzes …

Significance Of Residual Organisms In Foods After Substerilizing Doses Of Gamma Radiation: A Review, R. B. Maxcy

Department of Food Science and Technology: Faculty Publications

The nature of the flora surviving substerilizing irradiation of foods is dependent on the dose applied and the conditions of applications as well as the microenvi¬ronment of the food. At a dose level low enough to preserve acceptable sensory properties of fresh food, few if any of the common contaminants of public health significance survive irradiation. Survivors are weakened and present no unique problem of acquired resistance through recycling. Those bacteria surviving a low dose treatment of a relatively contaminated product like ground beef can grow under normal storage conditions and cause obvious sensory spoilage. Thus, low dose irradiation extends …

Foot Rot, Don Hudson

University of Nebraska-Lincoln Extension: Historical Materials

Foot rot (necrotic pododermatitis, foul foot) can be a very annoying problem in cattle. Once started in a herd and "seeded" in the soil, it may persist for quite a long time. Although the incidence of foot rot may not be high at any one time, it requires constant observation to prevent serious economic loss. The bacterium Fusobacterium necrophorum has been reported to cause foot rot. However, researchers have not been able to reproduce typical foot rot lesions with this organism. Recent research at the University of Missouri indicates that a combination of Fusobacterium necrophorum and Bacteroides melaninogenicus are the …
