Distribution And Abundance Of Three Freshwater Mussel Species (B1valv1a: U Ntontdae) Correlated With Physical Habitat Characteristics In An Iowa Reservoir, J. R. Straka, J. A. Downing
Distribution And Abundance Of Three Freshwater Mussel Species (B1valv1a: U Ntontdae) Correlated With Physical Habitat Characteristics In An Iowa Reservoir, J. R. Straka, J. A. Downing
Journal of the Iowa Academy of Science: JIAS
A rapid drawdown (weeks) of a reservoir allowed us to determine the combined influence of water depth, maximum effective fetch, bottom slope, and substrate characteristics on abundance of three species of freshwater mussels. The three principal mussel species were significantly (PPyganodon grandis(Say) was most abundant on deeper shelves (ca. 3 m depth, slope 1 km), and sediment organic matter content was moderate (Lampsilis siliquoidea(Barnes), however, was most abundant in shallow water (Potamilus alatus(Say) had a more cosmopolitan depth distribution, but was found only on bottoms with low slope (Pyganodon grandiswas found to be negatively affected by increasing substrate organic matter …
Population Size Estimates For The Endangered Iowa Pleistocene Snail, Discus Macclintocki Baker, Tama K. Anderson
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
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
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
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
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
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
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 …

Learning The Art Of Instructional Conversation: The Influence Of Self-Assessment On Teachers' Instructional Discourse In A Reading Clinic, Kathleen A. Roskos, Sophie Boehlen, Barbara J. Walker
Learning The Art Of Instructional Conversation: The Influence Of Self-Assessment On Teachers' Instructional Discourse In A Reading Clinic, Kathleen A. Roskos, Sophie Boehlen, Barbara J. Walker
Education
Over 2 decades of sociolinguistic research describe the teacher's powerful role in creating the communication system that supports students' learning. Yet research evidence about how to prepare and develop professionals for this role beyond their natural discourse tendencies and style remains sparse. This study examined self-assessment as a means of teacher learning that develops teachers' understanding and use of discourse strategies that support instructional conversation. Using a discourse analysis tool and related procedures (transcription, analysis, and interpretation), 9 teachers examined the conceptual and social functions of their talk from videotaped excerpts of tutorial instruction over 5 weeks. Although the teachers' …

Dawning Of The Age Of Quantitative/Empirical Methods In Accounting Research: Evidence From The Leading Authors Of The Accounting Review, 1966-1985, Robert James Fleming, Joel E. Thompson
Dawning Of The Age Of Quantitative/Empirical Methods In Accounting Research: Evidence From The Leading Authors Of The Accounting Review, 1966-1985, Robert James Fleming, Joel E. Thompson
Accounting Historians Journal
This study documents changes that took place in The AcÂÂcounting Review during 1966-1985 compared with earlier 20-year periods, 1926-1945 and 1946-1965. The comparisons are based on examining the articles published in The Accounting Review and writÂÂten by its leading authors (i.e., those authors who published the most articles). The article considers topics, research methods, finanÂÂcial accounting subtopics, citation analyses (including influential journals, articles, books, and authors), length, author background, and other items. This study shows that The Accounting Review evolved into a journal with demanding acceptance standards whose leading authors were highly educated accounting academics who, to a large degree, …
Knowing More As Knowing Less? Alternative Histories Of Cost And Management Accounting In The U.S. And The U.K., Keith W. Hoskin, Richard Macve
Knowing More As Knowing Less? Alternative Histories Of Cost And Management Accounting In The U.S. And The U.K., Keith W. Hoskin, Richard Macve
Accounting Historians Journal
In attempting to understand the genesis and scope of modÂÂern cost and management accounting systems, accounting historiÂÂans adopting what has been labeled a Foucauldian approach have been rewriting the history of key 18th and 19th century developÂÂments in the U.K. and U.S. through new evidence, new interpretaÂÂtion, and a refocusing of attention on familiar events. This is a disciplinary history which sees modern cost and management acÂÂcounting as articulating a new kind of expert disciplinary knowlÂÂedge, as well as exercising a disciplinary power, in the construcÂÂtion of a new human accountability. However, this disciplinary view has been challenged by more …

Water Resources Issues In The Arkansas Delta, Kenneth F. Steele
Water Resources Issues In The Arkansas Delta, Kenneth F. Steele
Arkansas Water Resources Center Technical Reports
Despite its location in Northwest Arkansas, the Arkansas Water Resources Center (AWRC) is active state-wide. This fact is underscored by the focus of the Center’s session on "Water Resource Issues in the Arkansas Delta" during its recent joint Conference. Water issues in the Delta include declining water tables, salt water intrusion, and water quality (especially suspended sediment, nitrate and pesticides). Presented papers focused on best management practices for cotton production, economics of on-farm reservoirs, chloride content of irrigation water, and landowner education. The AWRC short course was an excellent one on chemical transport in the vadose zone by Dr. Glenn …

An Hpspmd Programming Model, Bryan Carpenter, Geoffrey C. Fox, Guansong Zhang
Northeast Parallel Architecture Center
Building on research carried out in the Parallel Compiler Runtime Consortium (PCRC) project, this article discusses a language model that combines characteristic data-parallel features from the HPF standard with an explicitly SPMD programming style. This model, which we call the HPspmd model, is designed to facilitate direct calls to established libraries for parallel programming with distributed data. We describe a Java-based HPspmd language called HPJava.
