A Winter/Spring Study Of Salamanders In A Disturbed, Fragmented Habitat Surrounded By Farm Land, James C. Ball Jan 2000

A Winter/Spring Study Of Salamanders In A Disturbed, Fragmented Habitat Surrounded By Farm Land, James C. Ball

Journal of the Iowa Academy of Science: JIAS

The continued development of fragmented habitats contributes to the decline of amphibians species, and there needs to be a method for evaluating the potential of these habitats to sustain amphibian populations. The effect of fragmented and disturbed habitats among salamander species is difficult to assess because these caudates are difficult to find and enumerate. One approach for estimating the total population of salamanders is to sample them when they migrate to their winter/spring breeding ponds. One fragmented habitat in Southern Michigan was sampled for breeding salamanders during the winter/spring of 1997. Four species of salamanders were detected at this site; …


Reduction In Road Mortality In A Northern Leopard Frog Population, Madeleine H. Linck Jan 2000

Reduction In Road Mortality In A Northern Leopard Frog Population, Madeleine H. Linck

Journal of the Iowa Academy of Science: JIAS

Since spring of 1994, Hennepin Parks Natural Resources Management staff, assisted by numerous volunteers, has been working to reduce road mortality among migrating Northern Leopard Frogs (Rana pipiens) adjacent to Baker Park Reserve in Maple Plain, Hennepin County, Minnesota. A county road separates the overwintering site from breeding habitat within the park. With steadily increasing traffic over the years, this population of frogs was in serious decline. For the first two years (1994 and 1995) rescue efforts were limited to the spring collection of frogs as they migrated out of the overwintering lake coward the breeding wetlands, although the road …

"Well, Seriously, Flora, What Can We Women Do?" Sentimentalism, Suffrage And Reform In Lillie Devereaux Blake's Fettered For Life, Heidi Jacobs Jan 2000

"Well, Seriously, Flora, What Can We Women Do?" Sentimentalism, Suffrage And Reform In Lillie Devereaux Blake's Fettered For Life, Heidi Jacobs

LRI Participants' Publications (Peer Reviewed)

Summoning but reconfiguring the sentimental novel, Lillie Devereux Blake's Fettered for Life (1874) uses pathos to incite political action and begin a radical reform of patriarchal postbellum America. Of particular interest to Blake are suffrage, legal protection of women's lives and property, educational reform, and equitable pay and employment opportunities. In Fettered for Life there are eight suspicious or unnatural deaths which Blake links to a corrupt social order and archaic, ill-founded assumptions about women and womanhood. This article explores Blake's reform agenda and her use and revisioning of sentimentalism for rhetorical purposes.

Weed Seedbanks And Seedling Emergence In A Two And Three Crop Narrow Strip Intercropping/Rotation System, Shawn R. Wright, Douglas D. Buhler, Keith A. Kohler, Richard M. Cruse Jan 2000

Weed Seedbanks And Seedling Emergence In A Two And Three Crop Narrow Strip Intercropping/Rotation System, Shawn R. Wright, Douglas D. Buhler, Keith A. Kohler, Richard M. Cruse

Journal of the Iowa Academy of Science: JIAS

Weed populations in agronomic settings are, in part, a reflection of the cropping system utilized. The goal of this project was to gain an understanding of the weed population dynamics in a narrow strip intercropping (NSI) rotation by assessing the weed seedbank, weed emergence, and seedling establishment over the growing season for a corn-soybean (two-crop), and a corn-soybean-oat+berseem clover (three-crop) system. Field research was conducted in 1994 and 1995, near Nashua, IA, and each crop was grown m 4.6 m wide strips. Giant foxtail and total weed seed densities were significantly lower in the three-crop NSI rotation system than in …


Book Review: An Illustrated Guide To Iowa Prairie Plants, Paul Weihe Jan 2000

Book Review: An Illustrated Guide To Iowa Prairie Plants, Paul Weihe

Journal of the Iowa Academy of Science: JIAS

An Illustrated Guide to Iowa Prairie Plants. Paul Christiansen and Mark Müller. 1999. University of Iowa Press, Iowa City, Iowa. IX + 237 pages. ISBN 0-87745-660-7 hdbd., ISBN 0-87745- 661-5 pbk.

Iowans are increasingly aware of the significance of the tallgrass prairie, and efforts to preserve and protect this once-widespread ecosystem are ongoing. An obvious focus of these efforts 1s to conserve the native flora. When Bison and Elk disappeared from the landscape and row-crop agriculture appeared, a few of the native plants remained in old cemeteries, along roadsides, and in a few prairie remnants. Workers are now attempting to …

Introduction: A Perspective On Midwest Amphibian Declines, Gary S. Casper Jan 2000

Introduction: A Perspective On Midwest Amphibian Declines, Gary S. Casper

Journal of the Iowa Academy of Science: JIAS

On March 21, 1998, approximately 300 scientists and students gathered at the Milwaukee Public Museum for two days of scientific presentations and intense discussion on amphibian declines and malformities. Never before had so many persons come together to address amphibian conservation in the Midwestern United States (Minnesota, Wisconsin, Michigan, Illinois, Indiana, Ohio, Iowa, and Missouri).


Photo-Enhanced Toxicity In Amphibians: Synergistic Interactions Of Solar Ultraviolet Radiation And Aquatic Contaminants, Edward E. Little, Robin Calfee, Richard Skinker, Angela Zaga-Parkhurst, Mace G. Barron Jan 2000

Photo-Enhanced Toxicity In Amphibians: Synergistic Interactions Of Solar Ultraviolet Radiation And Aquatic Contaminants, Edward E. Little, Robin Calfee, Richard Skinker, Angela Zaga-Parkhurst, Mace G. Barron

Journal of the Iowa Academy of Science: JIAS

Amphibians experience a broad range of multiple environmental stressors that occur in natural systems. However, the impact of combinations of these stressors on amphibians are rarely examined. The effect of two stressors on amphibians, solar ultraviolet radiation (SUV) and environmental contamination, was investigated. To examine the interactive effects of SUV and environmental contaminants, Hyla venicolor and Rana sphenocephala were exposed in the laboratory to a carbamate insecticide and the water soluble fraction of a weathered petroleum in combination with various intensities of simulated solar radiation (SSR). The contaminants were tested at environmentally relevant concentrations. Synergistic interactions between SSR and these …


Landscape Associations Of Frog And Toad Species In Iowa And Wisconsin, U.S.A., Melinda G. Knutson, John R. Sauer, Douglas A. Olsen, Michael J. Mossman, Lisa M. Hemesath, Michael J. Lannoo Jan 2000

Landscape Associations Of Frog And Toad Species In Iowa And Wisconsin, U.S.A., Melinda G. Knutson, John R. Sauer, Douglas A. Olsen, Michael J. Mossman, Lisa M. Hemesath, Michael J. Lannoo

Journal of the Iowa Academy of Science: JIAS

Landscape habitat associations of frogs and toads in Iowa and Wisconsin were tested to determine whether they support or refute previous general habitat classifications. We examined which Midwestern species shared similar habitats to see if these associations were consistent across large geographic areas (states). Rana sylvatica (wood frog), Hyla versicolor (eastern gray treefrog), Pseudacris crucifer (spring peeper), and Acris crepitans (cricket frog) were identified as forest species, P. triseriata (chorus frog), H. chrysoscelis (Cope's gray treefrog), R. pipiens (leopard frog), and Bufo americanus (American toad) as grassland species, and R. catesbeiana (bullfrog), R. clamitans (green frog), R. palustris (pickerel frog), …


Amphibian Use Of Constructed Ponds On Maryland's Eastern Shore, Catherine E. Merovich, James H. Howard Jan 2000

Amphibian Use Of Constructed Ponds On Maryland's Eastern Shore, Catherine E. Merovich, James H. Howard

Journal of the Iowa Academy of Science: JIAS

Amphibian assemblages were sampled at nine constructed ponds (three in each age category: new ponds-age <1 yr, young ponds-age 4-5 yr, old ponds-age >30 yr) on Maryland's eastern shore (May-October 1994, March-August 1995) using a total of 27 drift fence and funnel trap arrays. The importance of habitat and landscape variables including pond age was considered in explaining amphibian use and distribution across ponds. Specifically, amphibian (1) abundance; (2) composition; (3) diversity; (4) richness; and (5) reproductive success were studied. During both years, we captured 1904 individuals comprising ten species. The most frequently collected species (species found in all treatments) were Bufo fowleri, Rana sphenocephala utricularius, and Rana …


Amphibians And Reptiles Captured In Drift Fences In Northwest Wisconsin Pine Barrens, James O. Evrard, Steven R. Hoffman Jan 2000

Amphibians And Reptiles Captured In Drift Fences In Northwest Wisconsin Pine Barrens, James O. Evrard, Steven R. Hoffman

Journal of the Iowa Academy of Science: JIAS

Drift fence surveys were initiated by the Wisconsin Department of Natural Resources (WDNR) in the Crex Meadows Wildlife Area (CMWA) in 1993. Systematic drift fence trapping of amphibians and reptiles in the northwest pine barrens was conducted in a 1996- 97 cooperative effort by the WDNR, the U.S. Forest Service (USFS), and the Great Lakes Indian Fish and Wildlife Commission (GLIFWC). Drift fences were operated in four managed barrens properties, the CMWA, Namekagon Barrens Wildlife Area (NBWA), the Douglas County Wildlife Area (DCWA), and the Moquah Barrens Wildlife Area (MBWA). Eighteen amphibian and reptile species (four salamanders, eight anurans, one …


Differences Among The Spatial Distribution Of Sympatric Amphibians, Robert Brodman Jan 2000

Differences Among The Spatial Distribution Of Sympatric Amphibians, Robert Brodman

Journal of the Iowa Academy of Science: JIAS

To assess amphibian declines, the factors that cause natural fluctuations in population size must be considered (Pechmann et al. 1991). Interspecific competition, predation and pond drying are known to influence patterns of distribution and composition of larval amphibian assemblages (Morin 1983, Brodman 1996, Skelly 1996). While a few studies have quantified amphibian patterns across a large number of ponds, most studies on breeding pond distributions have typically focused on pond characteristics associated with pairs of coexisting species (Thompson and Gates 1982, Skelly 1996). Little has been examined about the differences among the spatial distributions of all potentially interacting amphibian populations …


Amphibian And Reptile Surveys In The Kaskaskia River Drainage Of Illinois During 1997 And 1998, Allan K. Wilson Jan 2000

Amphibian And Reptile Surveys In The Kaskaskia River Drainage Of Illinois During 1997 And 1998, Allan K. Wilson

Journal of the Iowa Academy of Science: JIAS

Currently there is little doubt among the scientific community of the decline of amphibians on an international scale (Berger et al. 1998, Kuzmin 1994, Laurance et al. 1996, Lips 1998) and across North America (Delis et al. 1996, Drost and Fellers 1996, Lannoo 1994). In light of these widespread declines it is essential that current populations be inventoried and evaluated so that future population changes can be detected and hopefully correlated with possible causes. Critical baseline information is lost when monitoring is not implemented until after a problem is detected. The effectiveness of long-term studies in detecting amphibian declines (Beebee …

Higher Population And Twin Row Configuration Does Not Benefit Strip Intercropped Corn, M. M. Harbur, R. M. Cruse Jan 2000

Higher Population And Twin Row Configuration Does Not Benefit Strip Intercropped Corn, M. M. Harbur, R. M. Cruse

Journal of the Iowa Academy of Science: JIAS

Increased corn (Zea mays L.) grain yield with strip intercropping, made possible because of increased edge effects, makes this soil-conserving crop production system appealing to farmers. The objective of this study was to determine the population and row configuration needed to optimize the additional yield potential in each outside corn row. Treatments 'included: 74, 99, and 124 thousand plants ha-1 were grown in twin rows and 74 thousand plants ha-1 grown in single rows. Single rows or twin row centers were spaced 0.76 m. The experiment was conducted at four central Iowa sites during 1996 and 1997. Grain …


Prescriptive Travel And Adventure-Based Activities As Adjuncts To Counselling, Jeffery A. Kottler, Marilyn J. Montgomery Jan 2000

Prescriptive Travel And Adventure-Based Activities As Adjuncts To Counselling, Jeffery A. Kottler, Marilyn J. Montgomery

Faculty Publications - Graduate School of Counseling

One of the greatest challenges for counsellors is finding ways to promote constructive client actions outside sessions (Shelton & Levy, 1981). Often, clients perform well during therapeutic encounters but have difficulty applying what they have learned to real life situations (Stokes & Baer, 1977). In fact, inability to generalize learning is one of the most frequent problems encountered in our field (Rose, 1989).

Some of our most difficult and resistant clients are those who appear compliant, cooperative, eager, and solicitous in sessions but don't translate insights into action in their lives (Kottler, 1992), and don't continue their progress after treatment …

Science, Parents, Activities, And Literature: Overview, Results, And Reflections., James Shymansky, Larry Yore, John Dunkhase, Brian Hand

Educator Preparation & Leadership Faculty Works

This study examined elementary school students', parents', and teachers' reactions to instruction implemented by teachers participating in a special professional development program called Science: Parents, Activities and Literature (Science PALs). Specifically, this paper focuses on students' perceptions of their science instruction and attitudes toward science learning, and parents' and teachers' perceptions about science instruction as a function of their experience with an interactive-constructivist teaching approach designed to focus on student ideas, utilization of literature connections, and incorporation of parents as partners. Findings indicate that the Science PALs project successfully improved teachers' content-pedagogical knowledge in specific science units, pedagogical skills and …
