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 …

Corn (Zea Mays L.) Yield Response To Nitrogen Fertilizer In Conventional And Alternative Rotations, M. M. Harbur, M. Ghaffarzadeh, R. M. Cruse

Journal of the Iowa Academy of Science: JIAS

Nitrogen (N) fertilization recommendations are not available for corn in rotation with small grains or forages despite the possibility that the N response may differ from that of more conventional corn-soybean rotations. Rotations of corn with soybean (CS), corn with soybean and oat (CSO) and corn with soybean and an oat/berseem clover intercrop (CSOB) were established in 1991 and studied from 1993 through 1998 to determine the optimal N fertilization level for corn produced in each rotation. Corn in each rotation received NH4N03 applied at the rates of 0, 56, 112, or 168 kg N ha^-1. Significant differences …

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 …

Effects Of Altosid And Abate-4e On Deformities And Survival In Southern Leopard Frogs Under Semi-Natural Conditions, Donald W. Sparling

Journal of the Iowa Academy of Science: JIAS

Since 1995 when a group of school children in Minnesota found frogs with supernumerary limbs and missing limbs, there has been widespread interest in the amphibian malformation issue. Despite considerable effort to understand this problem, its extent and seriousness as well as direct causes of these malformations remain unclear. Progress on this issue has been hampered by a scarcity of scientifically reliable information on historical rates of abnormalities under undisturbed conditions and by the normal turnaround times of data collection, sample analysis and publication. One of the very few peer-reviewed publications with field-collected data showed that an average of 12% …

Field Investigations Of Malformed Frogs In Minnesota 1993-97, Judy C. Helgen, Mark C. Gernes, Susan M. Kersten, Joel W. Chirhart, Jeff T. Canfield, Dorothy Bowers, Jon Haferman, Robert G. Mckinnell, David M. Hoppe

Journal of the Iowa Academy of Science: JIAS

Reports of malformed frogs were made to the Minnesota Pollution Control Agency (MPCA) from different parts of Minnesota in 1993, 1995, 1996, and 1997 and one, nine, 190, and 172 reports were received, respectively. MPCA field crews and Drs. Hoppe and McKinnell documented malformed frog locations starting in 1993. By 1997, MPCA field crews documented malformed frogs at 62 locations in Minnesota, in 29 of 87 counties. Most malformations were in young metamorphs of Rana pipiens but they were observed also in R. clamitans, R. septentrionalis, R. sylvatica, Bufo americanus, and Hyla spp. Frequencies of malformations varied by time of …

Revitalization Of Ephemeral Pools As Frog Breeding Habitat In An Illinois Forest Preserve, Denins Nyberg, Irene Lerner

Journal of the Iowa Academy of Science: JIAS

Almost all land in the eastern United States that has been acquired to preserve nature was once in agricultural usage, and because of this, alterations of ephemeral pool hydrology are common in forest preserves and parks. These ephemeral pools are an important breeding resource for many amphibian species. We hypothesized that filling drainage ditches and recreating a more natural topography at eroded berms would enhance amphibian populations in the forest preserve. Restoration of the hydrology was begun by volunteers in 1993 and was associated with management to reduce non-native woody vegetation. Three ephemeral pools have had maximum water levels raised …

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 …

Rwanda, Burundi, And Their "Ethnic" Conflicts, Stephen B. Isabirye, Kooros M. Mahmoudi

Ethnic Studies Review

This paper demonstrably dispels the assumption that ethnic conflict in Rwanda and Burundi is a chronic endemic phenomenon. It emphasizes the consolidation of the caste system during the colonial era, intra regional disparities within the two communities, high population densities, very weak economic bases, poverty, and international interference as some of the cardinal dynamics behind the current deadly contentions within the two states. An analysis behind the genocidal tendencies in the two countries is well illustrated, with special emphasis on the Rwandese tragedy of 1994 as well as its parallels and divergences with the Nazi Holocaust.

Statement Of The Position Of The Iowa Academy Of Science On The Validity Of Evolutionary Science And On The Status Of Creationism As A Scientific Explanation Of Natural Phenomena

Journal of the Iowa Academy of Science: JIAS

Current attempts to introduce "scientific creationism", "creationism", or the Judeo-Christian biblical account of creation, as well as to reframe the discussion around terms such as "abrupt appearance theory", "intelligent design theory", or other disguised forms of creationism into the science classroom along with or instead of evolutionary science are strongly opposed by The Iowa Academy of Science on the grounds that creationism, in whatever form, is a religious doctrine and not science.
