Population Size Estimates For The Endangered Iowa Pleistocene Snail, Discus Macclintocki Baker, Tama K. Anderson Jan 2000

Population Size Estimates For The Endangered Iowa Pleistocene Snail, Discus Macclintocki Baker, Tama K. Anderson

Journal of the Iowa Academy of Science: JIAS

Discus macclintocki Baker, the Iowa Pleistocene snail, is a federally endangered species found only on algific talus slopes in northeastern Iowa and northwestern Illinois. Population size estimates for fourteen D. macclintocki populations in Iowa and Illinois ranged from 182 to 22,125 individuals. Estimates from the program CAPTURE as well as Bayesian estimation procedures gave similar results, although the Bayesian method allowed estimation of populations that could not be estimated with CAPTURE due to small sample sizes. A comparison of two methods of sampling, visual counts of quadrats and cover boards, showed that using cover boards resulted in much higher probabilities …

The North American Reporting Center For Amphibian Malformations, Douglas H. Johnson, Suzanne C. Fowle, Jeffrey A. Jundt Jan 2000

The North American Reporting Center For Amphibian Malformations, Douglas H. Johnson, Suzanne C. Fowle, Jeffrey A. Jundt

Journal of the Iowa Academy of Science: JIAS

The North American Reporting Center for Amphibian Malformations was established to provide a conduit of information about, and a systematic data base on, malformed amphibians. This article describes the Reporting Center and the variety of features available at its Web site, presents an example of a summary analysis that can be conducted with its data, discusses caveats about the data, and makes recommendations about systematic surveys to better understand patterns and trends in the incidence of malformed amphibians.

Demographic And Reproductive Characteristics Of A Southern Illinois Population Of The Crayfish Frog, Rana Areolata, Michael Redmer Jan 2000

Demographic And Reproductive Characteristics Of A Southern Illinois Population Of The Crayfish Frog, Rana Areolata, Michael Redmer

Journal of the Iowa Academy of Science: JIAS

Demographic (snout-vent length, skeletochronologically estimated age) and reproductive (fecundity, ova size) characteristics were examined in Riina areolata from Williamson County, Illinois. Fifty-nine frogs (36 males, 23 females) were sampled from breeding choruses in March 1996. Hematoxylinophilic annular lines of arrested growth (LAG) were detected in the diaphyses of cross-sectioned phalanges of all sampled frogs. t-tests revealed that male age (mean = 3.53 yr) and female age (mean = 3.83 yr) were not significantly different, but male SVL (mean = 82.78 mm) was significantly smaller than that of females (mean = 89.61 mm). There were positive correlations between SVL and age …

Herpetofaunal Abundance And Distribution In Northern Minnesota: Contributions Of Ecological Land Units And Assessment Of Sampling Methodology, Gabrielle Yaunches, S. R. Winterstein, H. Campa Iii, B. J. Kernohan, J. B. Haufler Jan 2000

Herpetofaunal Abundance And Distribution In Northern Minnesota: Contributions Of Ecological Land Units And Assessment Of Sampling Methodology, Gabrielle Yaunches, S. R. Winterstein, H. Campa Iii, B. J. Kernohan, J. B. Haufler

Journal of the Iowa Academy of Science: JIAS

Herpetofaunal species distributions need to be understood and mapped using landscape descriptions that incorporate important habitat features and ecological processes. An ecosystem management effort in northern Minnesota is characterizing a landscape as a coarse filter for ecological communities. The coarse filter approach involves looking at communities in different successional stages and habitat types in a region (Haufler et al. 1996). Documenting distributions and abundances of herpetofauna using this coarse filter approach will allow data about these species to be incorporated in landscape planning efforts.

Conclusions Drawn From The Malformity And Disease Session, Midwest Declining Amphibians Conference, 1998, Michael J. Lannoo Jan 2000

Conclusions Drawn From The Malformity And Disease Session, Midwest Declining Amphibians Conference, 1998, Michael J. Lannoo

Journal of the Iowa Academy of Science: JIAS

While the general problem of amphibian declines is well known, no issue recently has engendered as much concern by the public as amphibian malformities (Ouellet et al. 1996, Tietge 1996, Gray 1998, Helgen et al. 1998a and 1998b, D. Johnson 1998, T. Johnson 1998, Meteyer and Converse 1998). As a result, Gary Casper, Chris Phillips and I decided to assemble this symposium. The session was open to anyone who wished to participate. Nineteen papers were presented (there was one cancellation) and a panel discussion followed. I will organize this summary of, and conclusions drawn from, our symposium into two sections: …

Limits To Ice Thickness In Iowa During The Late Wisconsinan, Eric C. Brevik Jan 2000

Limits To Ice Thickness In Iowa During The Late Wisconsinan, Eric C. Brevik

Journal of the Iowa Academy of Science: JIAS

Minimum and maximum limits to Des Moines Lobe ice thickness in Iowa during the Late Wisconsinan glaciation are calculated. These limits are based on minimum and maximum ice thickness calculations for the Des Moines Lobe in eastern North Dakota using crustal depression indicated by Lake Agassiz strandlines. Minimum and maximum basal shear stresses for the Des Moines Lobe are calculated by projecting a flow line from the terminus of the Des Moines Lobe back up-ice to the study site in northeastern North Dakota. Ice thickness in Iowa is then calculated with a method that uses the basal shear stress values. …

Field Surveys Of Midwestern And Northeastern Fish And Wildlife Service Lands For The Presence Of Abnormal Frogs And Toads, Kathryn A. Converse, James Mattsson, Laura Eaton-Poole Jan 2000

Field Surveys Of Midwestern And Northeastern Fish And Wildlife Service Lands For The Presence Of Abnormal Frogs And Toads, Kathryn A. Converse, James Mattsson, Laura Eaton-Poole

Journal of the Iowa Academy of Science: JIAS

The national distribution of information on the discovery of malformations in Minnesota frogs in 1995 stimulated collection and examination of newly metamorphosed frogs during 1996. By late summer and early fall of 1996, malformed frogs and toads were reported on U.S. Fish and Wildlife Service (USFWS) lands in Vermont (Northeast, Region 5) and Minnesota (Midwest, Region 3). In response to these reports, biologists in USFWS Regions 3 and 5 conducted a survey, during the summer of 1997 to determine the distribution and type of malformations in frogs and toads on selected Federal lands. Region 3 personnel surveyed 38 field stations …

Transcending Cultural Definitions: A Sense Of Peace, Susan Sanae Sakayori Jan 2000

Transcending Cultural Definitions: A Sense Of Peace, Susan Sanae Sakayori

MA TESOL Collection

Who am I? What am I? This paper is an attempt to tell a personal story of my struggle to answer these questions about my racial and cultural identity. As a Japanese American who has lived the first half of my life in the U.S. and the latter half in Japan, I found it increasingly difficult to find my place in either culture. I was faced with issues of ethnicity, cultural background and personal values that I didn’t realize were so important in understanding who I was. I have traveled down a road of discovery where I was given a …

How Wisconsin Farmers Feed Theircows: Results Of The 1999 Wisconsin Dairy Herd Feeding Study, Douglas B. Jackson-Smith, J. M. Powell Jan 2000

How Wisconsin Farmers Feed Theircows: Results Of The 1999 Wisconsin Dairy Herd Feeding Study, Douglas B. Jackson-Smith, J. M. Powell

Sociology, Social Work and Anthropology Faculty Publications

The Wisconsin dairy industry has seen dramatic changes over the last 20 years (Jackson- Smith and Barham, 2000). Overall, dairy farm numbers have been cut in half since the early 1980s, and the average size of remaining herds has increased by more than 60 percent (from roughly 40 cows to over 65 cows per herd). Despite these changes, most dairies are still single-family businesses, relying on household members for virtually all their farm labor requirements (Buttel et al., 2000). In 1998, state statistics suggested that over 70 percent of Wisconsin dairy operations were milking between 30 and 99 cows, and …

Identifying Sources Of Prehistoric Turquoise In North America: Problems And Implications For Interpreting Social Organization, Frances Joan Mathien Jan 2000

Identifying Sources Of Prehistoric Turquoise In North America: Problems And Implications For Interpreting Social Organization, Frances Joan Mathien

BEADS: Journal of the Society of Bead Researchers

Well-made turquoise beads are rare in North American archaeological sites, and the prehistoric sources of turquoise are limited. Mining the turquoise, manufacturing the bead, and using it as part of a bracelet or necklace involve numerous human interactions to transport the raw material from its source to the place where it is finally found in an archaeological context. Accurate identification of turquoise sources affects our interpretation of prehistoric behavior and is the focus of this paper.

Man-In-The-Moon Beads, Michele Lorenzini, Karlis Karklins Jan 2000

Man-In-The-Moon Beads, Michele Lorenzini, Karlis Karklins

BEADS: Journal of the Society of Bead Researchers

The unique and memorable design of man-in-the-moon beads has intrigued researchers over the years. These distinctive beads were identified in the 1960s by George Quimby as being chronologically diagnostic of Middle Historic Period sites (1670-1760) in the western Great Lakes region. The present study more clearly defines both the temporal and geographical instances of man-in-the-moon beads while taking into account possible cultural and historical implications. This project has led to the compilation of information regarding many specimens previously unknown to most researchers.

Cultural Atrocity Expressed In Cultural Art, Marlie Mcgovern Jan 2000

Cultural Atrocity Expressed In Cultural Art, Marlie Mcgovern

Inquiry: The University of Arkansas Undergraduate Research Journal

Some of the most horrific chapters in human history have involved an ethnic dimension, notably the centuries-long obliteration of traditional Nigerian cultures by European colonizers, the attempted destruction of European Jews in the Holocaust, and the World War ll decision to assault the Japanese with atomic bombs. The consequences of the above atrocities are not contained within temporal or cultural barriers, but hold profound and pervasive ramifications within contemporary society in its entirety. More recent conflicts in Africa, Southeast Asia and the Balkans reemphasize the horror and suffering brought about by cultural collisions. One of the most potent reactions to …

A Framework For Assessing The Suitability Of Different Species As Companion Animals, C. A. Schuppli, D. Fraser Jan 2000

A Framework For Assessing The Suitability Of Different Species As Companion Animals, C. A. Schuppli, D. Fraser

Wild and Exotic Animals as Pets Collection

Municipal regulations and humane movement policies often restrict or discourage the use of 'exotic' species as companion animals. However, confusion arises because the term 'exotic' is used in various ways, and because classifying species as exotic or non-exotic does not satisfactorily distinguish suitable from unsuitable companion animals. Even among commonly kept species, some appear to be much more suitable than others. Instead, decisions about suitable companion animal species need to be based on a number of relevant issues. As ethical criteria, we considered that keeping a companion animal should not jeopardize - and ideally should enhance - its welfare, as …

The Status Of Animals In Biblical And Christian Thought: A Study In Colliding Values, Rod Preece, David Fraser Jan 2000

The Status Of Animals In Biblical And Christian Thought: A Study In Colliding Values, Rod Preece, David Fraser

Morality and Religious Philosophy Collection

A common contemporary view is that the Bible and subsequent Christian thought authorize humans to exploit animals purely as means to human ends. This paper argues that Biblical and Christian thought have given rise to a more complex ethic of animal use informed by its pastoralist origins, Biblical pronouncements that permit different interpretations, and competing ideas and doctrines that arose during its development, and influenced by the rich and often contradictory features of ancient Hebrew and Greco-Roman traditions. The result is not a uniform ethic but a tradition of unresolved debate. Differing interpretations of the Great Chain of Being and …
