A Sociobiological Perspective On The Development Of Human Reproductive Strategies, Patricia Draper, Henry Harpending

Department of Anthropology: Faculty Publications

Humans show a great deal of variability in their reproductive behavior, including types of sexual activity, types of ties between males and females, and ways of arranging for the rearing of offspring. We will consider three principal topics: (1) Father absence versus father presence, contrasting children who are reared in a family system in which there is a closely involved and economically contributing father in contrast to a family system in which women rear their children in cooperation with other women (usually kin) and without consistent help from a man who is father to children. (2) Peer rearing versus parent …

Science Concepts Taught In Secondary Vocational Agriculture Programs As Perceived By Nebraska Secondary Vocational Agriculture And Science Instructors, Thomas L. Sabata

Department of Agricultural Leadership, Education, and Communication: Dissertations, Theses, and Student Research

The study was conducted to identify the science concepts taught in the vocational agriculture curriculum which are the same as science concepts considered necessary in the secondary science curriculum in Nebraska, as perceived by 33 vocational agriculture instructors and science instructors in earth science (24), biology (30), physics (28) and chemistry (28). A mail survey was used to collect data for the study. The survey return rate for the vocational agriculture teachers was 75 percent; while science teacher returns were lower (54.5 to 68.2%). Science concepts were rated on a scale of 1 to 5 of importance for students to …

Population Dynamics Of Distoichometra Bufonis (Cestoda: Nematotaeniidae) In Bufo Woodhousii, John J. Janovy Jr., Eugene Lee Hardin

John J. Janovy, Jr. Publications

Prevalence, density, and variance/mean (= variance/density) ratios are reported for the cestode Distoichometra bufonis in 28 samples of the amphibian host, Bufo woodhousii, taken over a 3-yr period at two study sites on the South Platte River in Keith County, Nebraska, U.S.A. In addition, changes in host demography resulting from entry of newly metamorphosed toads into the terrestrial population are given. Prevalence and density (average number of worms per host, infected + noninfected) did not vary significantly either within or between sites and years unless newly metamorphosed toads were included in the analysis. Prevalence ranged from 70 to 100%, …

Foraging Behavior And Switching By The Grasshopper Sparrow Ammodramus Savannarum Searching For Multiple Prey In A Heterogeneous Environment, Anthony Joern

School of Biological Sciences: Faculty Publications

Switching among four alternative grasshopper species by the grasshop- per sparrow (Ammodramus savannarum) through frequency-dependent predation was ex- amined. Grasshoppers were presented against a heterogeneous natural background in an outdoor aviary where total density was held constant but relative density of each grasshopper species varied. Switching among prey, primarily between two of the four species, and inter-bird variability in switching was observed. Species-specific prefer- ences and interactions among the alternative grasshopper species affected the final diet choice as one grasshopper species was always preferentially selected and another disregarded independent of changes in relative density. Attributes of avian foraging behavior, including: …

Eimeria From Bats Of The World. Ii. A New Species In Tadarida Femorosacca From Sonora, Mexico, Donald W. Duszynski, David W. Reduker, Brent B. Parker

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Between 1979 and 1980, 104 bats representing 13 species in 4 families were collected in California and New Mexico, U.S.A., and Baja California and Sonora, Mexico, and were examined for coccidia; only 3 (3%) had oocysts in their feces. Bats examined and their infection rates were: Molossidae: 0 of 12 Tadarida brasiliensis, 1 of 18 (6%) T. femorosacca; Natalidae: 0 of 1 Natalus stramineus; Phyllostomatidae: 0 of 1 Choeronycteris mexicana, 0 of 2 Leptonycteris sanborni, 0 of 1 Macrotus californicus; Vespertilionidae: 0 of 9 Antrozous pallidus, 0 of 28 Eptesicusfuscus, 0 of …

Comparison Of Heritability And Variation For Milk Yield Of Registered And Non-Registered Holstein Cows, L. Dale Van Vleck, J. C. Schneider, C. P. Van Tassell

Department of Animal Science: Faculty Publications

First lactation milk records of AI Holstein cows in the northeastern United States were analyzed for among and within-sire variation separately by year of freshening, class of herd production, and registry status of registered or nonregistered with a model that included effects of herd-seasons, sires of sampling daughters, and sires of daughters of proven sires. Heritability from the paternal half-sib correlation among records of daughters of sampling sires was similar for registered and nonregistered cows. Differences in heritability in different years and class of herd production were similar to those found in previous analyses that ignored registry status. Residual variances …

The Pest Control Industry And The Challenges Ahead , Lee C. Truman

Vertebrate Pest Conference Proceedings: 13th (1988)

The pest control industry, whether it be governmental, urban, aerial, lawn and turf, trees, or whatever, has many of the same problems. Controllers of vertebrate or invertebrate pests, or plant pests, have much in common. Environmental¬ists talk of the "balance of nature," usually overlooking the fact that nature is more often out of balance than in balance. Nature is cruel in its control of plant and animal species whenever there is not enough food to go around or enough of a suitable habitat in which to live. Nature does not conserve things as they are but, rather, changes them and …

Pesticides, Scientists, Farmers, And The Public: No "White Knight" Rescue In Sight, Pamela Jones

Vertebrate Pest Conference Proceedings: 13th (1988)

ABSTRACT: The pesticide controversy is much more complicated than simply a disagreement over facts and risk estimates between the "experts" and the "fearful." It is a battle over ideology as much as one over information. This paper discusses the notion of "educating the public" about pesticides, establishing realistic expectations of efforts by industry and academia, and notes some of the limitations, and potential involvement, of scientists as "translators" in dealing with this controversy.

Animal Rights And Vertebrate Pest Control, Dale L. Brooks

Vertebrate Pest Conference Proceedings: 13th (1988)

ABSTRACT: Many animal rights activists are very vocal in their belief that animals are more valuable or at least equally important to humans. There is little to no compromise in their overall view that the use of animals for food, fiber, teaching, research and testing does not result in improvements for other animals or societal needs. Today's activists are well prepared and very articulate in getting their views across to the public through the press and television media. An increasing number of the public is beginning to believe the activist allegations of inhumane animal practices. The biologist can no longer …

Attitude Change Toward Vertebrate Pest Control, Robert M. Timm, Sanford D. Schemnitz

Vertebrate Pest Conference Proceedings: 13th (1988)

ABSTRACT: Attitudes of students enrolled in courses on wildlife damage control at two universities were surveyed at the beginning and end of the semester. Attitudes toward wildlife and acceptance of various damage control methods were quantified and compared to responses obtained from the general public in previous surveys. As a result of the class, both groups of students generally became more accepting of current vertebrate control practices, including toxicant use. Student attitudes, as a result of knowledge gained, came to be more realistic and practical. We believe that persons, when presented factual information about wildlife damage and its control, will …

Urban Wildlife: Can We Live With Them?, Wayne R. Marion

Vertebrate Pest Conference Proceedings: 13th (1988)

ABSTRACT: A survey of Extension Wildlife Specialists in the U.S. provided a basis for estimating the magnitude of urban wildlife damage and control in this country. Response to the 9-question mail questionnaire was good (76 percent) following the single mailing to all Extension Wildlife Specialists or people in similar positions listed in the national directory. The majority of questions were answered based upon the experiences and best estimates of these specialists for the interval October 1986-September 1987. Specialists had difficulty providing estimates of damage and costs of prevention and control; 57 percent were not able to provide any data on …

Vertebrate Pesticides And Nontarget Wildlife Losses In Proper Perspective, James E. Miller

Vertebrate Pest Conference Proceedings: 13th (1988)

ABSTRACT: The use of pesticides as one of the management tools to assist in the prevention and control of damage caused by vertebrate wildlife is certainly not new, nor has it become any less controversial in recent years. In fact, throughout the recent history of pesticide uses for control of vertebrate damage to the production of food and fiber, the prevention of potential epizootic diseases, and other potential threats to man's well-being and to the habitats and management of other wildlife resources, the use of pesticides as well as other management tools have generally been reviewed and monitored by professionals. …

Activity Of Lm 2219 (Difethialone), A New Anticoagulant Rodenticide, In Commensal Rodents, J. C. Lechevin, Richard M. Poche

Vertebrate Pest Conference Proceedings: 13th (1988)

ABSTRACT: Preliminary studies completed on commensal rodents with the new anticoagulant rodenticide difethialone showed very good efficacy, such that 25 ppm baits could be used effectively. New test results presented in this publication confirm the activity as shown under laboratory conditions in choice tests, which represent more severe conditions, as well as its effectiveness against rodents that are resistant and non-resistant to warfarin. In tests where the palatability was only fair the chemical activity resulted in excellent mortality. In a field test against a large population of Mus musculus the results proved very satisfactory. Difethialone is toxic to birds and …

Status Of Bromethalin Outside The United States , S. R. Spaulding, H. Spannring

Vertebrate Pest Conference Proceedings: 13th (1988)

ABSTRACT: Bromethalin has been extensively researched over the past decade in the United States, Switzerland, England, Denmark, and France. United States EPA registrations were received in 1982 and commercial pelleted formulations containing 0.01% bromethalin were developed and introduced in the USA by Ralston Purina (ASSAULT1*) in 1985 and Velsicol (VENGEANCE1*) in 1986. Ciba-Geigy is currently developing new formulations under the tradename DORATIDR for use outside the United States. Bromethalin acute toxicity and 14-day subchronic studies are reviewed and data from recently completed 90-day subchronic studies required for registration outside the US are presented. Pharmacodynamic studies have shown that bromethalin acts …

Efficacy And Environmental Impact Of Flocoumafen (Storm) Wax Block Baits Used For Rice Field Rat Control In The Philippines., Melanda M. Hoque, Jaime L. Olvida

Vertebrate Pest Conference Proceedings: 13th (1988)

Two large (approx. 160 ha) trial sites incorporating ricefields and village housing were selected in Laguna Province, Philippines. Flocoumafen 3.5-g wax block baits (StormR) were applied to one site, initially as two area-wide pulses of 80 to 100 blocks/ha and later as spot treatments, to areas of particularly high rat infestation. Baiting in and around the village houses was already carried out during the first two applications. On average, only 1.175 kg/ha/season of flocoumafen block bait gave good rodent control resulting in significant decreases in crop damage (% cut tillers) compared to the untreated area. The overall yield increase was …

Efficacy Of Trimethac Arb As A Small Mammal Repellent In No-Till Corn Plantings, George H. Matschke, William R. Bonwell, Richard M. Engeman

Vertebrate Pest Conference Proceedings: 13th (1988)

Trimethacarb (2,3,5-trimethylphenyl methycarbonate) was evaluated as a mouse repellent in no-till corn plantings. Two studies were conducted. One involved an early spring planting and included 5 treated and 5 control plots. The second involved a late spring planting and included 3 treated and 3 control plots. Species composition and relative abundance of small mammals were determined for each plot by trap and release before treatment. On the 10 early spring plots, species composition was 85% prairie voles (Microtus ochrogaster). 14% deer mice (Peromyscus spp.). and 1% house mice (Mus musculus'). On the 6 late spring plots, species composition was 66% …

Vitamin Kt Treatment Of Brodifacoum Poisoning In Dogs, C. G. Mackintosh, F. J. Laas, M. E. R. Godfrey, K. Turner

Vertebrate Pest Conference Proceedings: 13th (1988)

Twenty dogs received a potentially lethal (15 mg/kg) dose of brodifacoum, a halogenated coumarin-type anticoagulant poison. Eleven were immediately treated with vitamin K: daily for 5 days, either by intramuscular injections (2 mg/kg) or oral tablets (1 mg/kg). It was necessary to give further doses of vitamin Kj to most of the dogs for up to 2 weeks after the first treatment period to reduce their P times to normal levels (<10 >seconds). Four dogs were not given further vitamin Kj and two of these died of acute blood loss from an intrathoracic hemorrhage. Nine dogs received vitamin K: (2 …
