The Status Of Iowa's Lepidoptera, Dennis W. Schlicht, Timothy T. Orwig

Journal of the Iowa Academy of Science: JIAS

Including strays, 122 species of butterflies have been confirmed in Iowa. However, since European settlement the populations of taxa of Iowa Lepidoptera have declined. While certain generalist species have experienced declines, species with life cycles that include native habitats, especially prairies and wetlands, have been particularly vulnerable. In a 1994 revision of the Iowa endangered and threatened species list, the Natural Resource Commission (NRC) listed two species of butterflies as endangered, five as threatened, and 25 as special concern, using general legal definitions of those rankings (NRC 1994). But after examining recent records, we have revised that list, using numbers …

Mammals Of Iowa: Holocene To The End Of The 20th Century, John B. Bowles, Daryl L. Howell, Richard P. Lampe, Howard P. Whidden

Journal of the Iowa Academy of Science: JIAS

This review of Iowa's mammal fauna at the close of the 20th century summarizes changes in distributional patterns following Euroamerican settlement in the early 1800s. Data from historical records, museum specimens, and presettlement late Holocene fossils indicate presence of 69 resident mammals at that time. Hunting pressures and the conversion of prairie and forest to agricultural fields reduced the populations and ranges of many state mammals, and 14 species were extirpated by 1900. An additional 15 species are either uncommon or rare today, and the Iowa Department of Natural Resources lists four species as endangered, three as threatened and one …

This volume is based on an international conference, “Natural Resource Use Relations in the Trinational Sangha River Region of the Northwest Congo Basin,” held at Yale University in September 1997. In recognition of the bilingual context in which conservation occurs in the three countries of the Sangha region — Cameroon, Central African Republic, and Congo — all sessions of the conference were conducted simultaneously in French and English. This publication, which is a complete rendering of the conference papers and discussion sessions, is available in its entirety in both French and English.

Mummies And Mummification Practices In The Southern And Southwestern United States, Mahmoud Y. El-Najjar, Thomas M. J. Mulinski, Karl Reinhard

Karl Reinhard Publications

Mummification was not intentional for most North American prehistoric cultures. Natural mummification occurred in the dry areas of North America, where mummies have been recovered from rock shelters, caves, and overhangs. In these places, corpses desiccated and spontaneously mummified. In North America, mummies are recovered from four main regions: the southern and southwestern United States, the Aleutian Islands, and the Ozark Mountains of Arkansas. This chapter is limited to a discussion of burial practices and a tabulation of the location of mummies in the southwestern United States with some comments on mummies of the southern United States, including the Ozarks.

Human Dental Microwear Caused By Calcium Oxalate Phytoliths In Prehistoric Diet Of The Lower Pecos Region, Texas, Dennis Danielson, Karl Reinhard

Karl Reinhard Publications

Recent research demonstrates that silica phytoliths of dietary origin are associated with microwear of human teeth. Previous research has shown that severe enamel microwear and dental wear characterizes Archaic hunter-gatherers in the lower Pecos region of west Texas. Calcium oxalate crystals are especially common in Archaic coprolites. The vast majority are derived from prickly pear and agave, which were the dietary staples in west Texas for 6,000 years. The calcium oxalate phytoliths are harder than enamel. Therefore, calcium oxalate crystals are the most likely source of previously documented dental microwear and wear in the lower Pecos region.Am J Phys Anthropol …

The Effects Of Aerobics And Walking On Social Physique Anxiety And Self-Esteem Of Female College Students, Jessica L. Lloyd

College of Graduate Studies: Theses & Dissertations (1964–2006)

The purpose of this investigation was to explore the effectiveness of walking and aerobics as a way of modifying body image apprehension and self-esteem of female college students. Participants from this study comprised 88 (25 African Americans and 63 Caucasians) students from a Southeastern university. The participants were administered the 9-item Social Physique Anxiety Scale (SPAS) (Martin, Rejeski, Leary, McAuley, & Bane, 1997) and the Rosenberg Self-Esteem Scale (RSES) (Rosenberg, 1979). Body composition, body weight, body height, and body mass index (BMI) were also evaluated. The participants performed in a 9-week walking or aerobics physical activity class. At the completion …

The Magnitude Of Site And Time Interaction Effect In Tsetse Fly (Diptera: Glossinidae) Trap Catches, A. Odulaja, S. Mihok, I. M. Abu-Zinid

All Peer-Reviewed Publications

Site and time effects are important factors determining trap catches of tsetse flies. These factors may interact significantly and therefore confound interpretation of time series data used for population monitoring. We therefore investigated the magnitude and importance of site x time interactions in trap catches of Glossina pallidipes Austen and G. longipennis Corti using a 2200 trap-days (400 trap-months) data set. The interaction was found to be significant (P < 0.05) in 46-100% of the combinations of different numbers of months and sites between 2 and 12. The mean percent variance due to the interaction ranged between 4% and 28% for G. pallidipes and 12% and 36% for G. longipennis. The interaction was usually less important than the effect of site alone but more important than the effect of time alone. These results suggest that tsetse researchers should examine critically the adequacy of existing approaches to population monitoring with traps and to testing new traps and odour baits.

Olfactory Responses Of Glossina Fuscipes Fuscipes (Diptera: Glossinidae) To The Monitor Lizard Varanus Niloticus Niloticus, M. M. Mohamed-Ahmed

All Peer-Reviewed Publications

Visual and olfactory responses of Glossina fuscipes fuscipes Newstead to the monitor lizard, Varanus niloticus niloticus Laurenti were studied using various catching devices near Lake Victoria, Kenya. Electric nets baited with visible lizards caught more males (x2.1) and significantly more females (x2.0) than unbaited nets. Lizards concealed in electrified black Pvc pipe models, simulating the shape and size of a monitor lizard, increased significantly the catches of tsetse by 2.1 times. Fresh lizard urine dispensed at an evaporation rate of 500 to 1000 mg/h also increased significantly the catches of flies at biconical traps, electrified models and electric nets. Identification …

Iowa Prairie: Original Extent And Loss, Preservation And Recovery Attempts, Daryl D. Smith

Journal of the Iowa Academy of Science: JIAS

Iowa's prairie has to be assessed in the context of the pre- and post-agriculturally dominated ecosystem in which it now exists. This requires an understanding of prairies and of society's perspective of prairies. Therefore, the attitudes of people through time have to be considered; (1) those who were involved in the demise of the prairie, (2) those who helped saved the pieces of the prairie and (3) those who may be called upon to recover the prairie ecosystem.

Puncturing Ability Of Bat Canine Teeth: The Tip, Patricia W. Freeman, William N. Weins

University of Nebraska State Museum: Mammalogy Papers

Casts of upper canine teeth of 15 species of microchiropteran bats were fixed securely into a testing machine and made to puncture the bloom side of an apple. The force necessary to break through the surface of the apple was regressed against both shape of the tip of the canine and the size of the animal. Sharper tips require less force to puncture than blunt ones. Results were also verified using giant two-dimensional models of Plexiglas™ with sharp and blunt tips that were loaded onto a Plexiglas™ beam. Fringes, or stress lines, are more highly concentrated at the point of …

Postnatal Observations Of Behavioral Patterns Within The Social Organization Of Captive Bottlenose Dolphins (Tursiops Truncatus), Stacey R. Hanson

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Mirage Dolphin Environment opened in 1991. The Mirage has eight Atlantic Bottlenose dolphins. Four of these dolphins were relocated to the facility from other facilities that were either overcrowded or shutting down. The other four were born at the Mirage. The purpose and intent of the Mirage Dolphin Environment is to provide a nurturing environment for the dolphins and to educate the public about marine mammals and their ecosystems. The increased awareness associated with education will hopefully encourage public support for efforts to conserve and protect marine mammals and their environment.

Conservation biology is a multidisciplinary subject of recent origins. Analysis of cited monographs from the journal Conservation Biology resulted in a list of 47 monographs which were heavily cited for this discipline. Over half of these were from related disciplines such as ecology, genetics, evolution, population biology, statistics, and natural resource management.

The Use Of Plot Surveys For The Study Of Ethnobotanical Knowledge: A Brunei Dusun Example, Jay H. Bernstein, Roy Ellen, Bantong Bin Antaran

Publications and Research

This paper describes a technique for using plot surveys to measure individual informants' ethnobotanical knowledge of forests, as applied to the Dusun community of Merimbun in Brunei. Two knowledgeable but non-literate Dusun informants enumerated marked plots of both recent and old secondary growth mixed dipterocarp forest near the village. They were able to provide names (other than life-forms or the most general basic and intermediate categories) for 86-97% of species growing in the plots. Between 152 and 170 plant names were elicited by the surveys. In all cases, about 88% of the names were at the basic naming level and …

Ecological Life History Of Crangonyx Pseudogracilis Bousfield (Crustacea: Amphipoda) In The Green Bottom Wildlife Management Area, Cabell County, West Virginia, Andrea Leigh Henry

Theses, Dissertations and Capstones

Although the genus Crangonyx has been studied in the Appalachian area, most of this work has concentrated on subterranean species. A Crangonyx pseudogracilis population from the Green Bottom Wildlife Management Area (GBWMA), Cabell County, West Virginia was sampled weekly from March 1995 through July 1996 to investigate the ecological life history of the amphipod. A total of 1508 amphipods were collected. Amphipods were present in the study sites from November through July, at which time they migrated to deeper waters. Crangonyx pseudogracilis had a one year life cycle and bred from November to May. Adult amphipods began to die off …

Forest Research In Iowa's State Parks - The Values Of Natural Diversity, Donald R. Farrar

Journal of the Iowa Academy of Science: JIAS

Approximately 3% of Iowa's forests are contained in state parks and preserves. In addition to aesthetics and recreation, these protected forests provide a vital service in the unique opportunities they provide for forest research. As intact ecosystems where natural ecological processes dominate, they provide standards by which we measure the effects of livestock pasturing, methods of timber harvest, and other manipulations of managed forests. A number of current studies and public programs emphasize the importance of natural diversity in forests. They rely on state parks and preserves to provide a measure of potential diversity for a given region of the …

Grounds For Argument: Local Understandings, Science, And Global Processes In Special Forest Products Harvesting, Thomas Love, Eric Jones

Faculty Publications

In posing the question "Where are the pickers?", Love and Jones suggest that the shifting paradigm in forestry is real and that academia is not leading the shift. Love and Jones illustrate the emergence of special forest products' legitimacy in competing uses of forests with their experience and research in mushroom harvesting in the Pacific Northwest.
