Changes In Land Cover And Breeding Bird Populations With Restoration Of Riparian Habitats In East-Central Iowa, Thomas J. Benson, James J. Dinsmore, William L. Hohman

Journal of the Iowa Academy of Science: JIAS

Conversion of Midwestern riparian areas for agricultural production has greatly altered their function and suitability for birds and other wildlife. Recently, however, restoration of riparian functions has been a major focus of land management agencies in the Midwest. We used historic land-use data to describe land-cover changes since European settlement and the subsequent effects of habitat restoration efforts on the landscape along a section of the Iowa River in east-central Iowa. We then used bird-density data collected in a subset of the study area in 2001 and 2002 to estimate changes in breeding bird populations of the entire study area …

Predation And Cathemerality. Comparing The Impact Of Predators On The Activity Patterns Of Lemurids And Ceboids., Ian C. Colquhoun

Anthropology Publications

The removal, or absence, of predatory species could be a contributing proximate factor to the rise of primate cathemerality. But predators themselves can also be cathemeral, so cathemerality could well be an evolutionary stable strategy. From a comparative perspective, it appears that the effect of predatory species cannot provide a unitary explanation for cathemerality. Varying distributions and population densities of predators, especially raptors, may be key factors in owl monkey (Aotus) cathemerality, but temperature and lunar cycle variation have also been implicated. In Madagascar, while raptors are potential predators of lemur species, the cathemerality of Eulemur species coincides with that …

Use Of Artificial Enclosures To Determine The Survival Of Rana Pipiens Larvae In Upper Midwestern Agricultural Ponds, Joshua M. Kapfer, Mark B. Sandheinrich, Melinda G. Knutson

Journal of the Iowa Academy of Science: JIAS

Amphibians in the upper Midwest use agricultural ponds for breeding. Unfortunately, the risks (both direct and indirect) associated with using these ponds are poorly understood in both amphibian adults and larvae. In order to quantify these risks, we performed a comparison of larval survival rates between agricultural and natural ponds in southeastern Minnesota during the spring and summer of 2001. During this time, larval survival was observed in Rana pipiens tadpoles raised through metamorphosis in enclosures placed in agricultural and natural ponds. In addition, we measured the levels of nutrients commonly linked with agricultural ponds (i.e., ammonia, total phosphorous, and …

Artists' Depictions Of Catsteps In The Loess Hills Of Iowa: Evidence For Mid-Nineteenth Century Climate Change, Kimberly R. Dillon, Steven H. Emerman, Pamela K. Wilcox

Journal of the Iowa Academy of Science: JIAS

Catsteps are the staircase-like features common on hillslopes of the Loess Hills of western Iowa. The record of artistic depictions of the Loess Hills was examined to determine when catsteps appeared. George Catlin, Karl Bodmer, and John James Audubon traveled up the Missouri River m 1832, 1833 and 1843, respectively, and between them, produced 31 works of art depicting either the Loess Hills or the loess bluffs on the Nebraska side of the river. Only three works by Bodmer of Blackbird Hill on the Nebraska side possibly show catsteps. The Assistant State Geologist, Orestes St. John, produced six sketches of …

Relation Of Riparian Buffer Strips To In-Stream Habitat, Macroinvertebrates And Fish In A Small Iowa Stream, Jeremy P. Duehr, Michael J. Siepker, Clay L. Pierce, Thomas M. Isenhart

Journal of the Iowa Academy of Science: JIAS

Macroinvertebrate and fish habitat is often degraded as a result of agriculture. Riparian buffer strips are commonly used to counteract the negative effects of agriculture in headwater streams. We assessed the relation of multi-aged riparian buffer strips to in-stream habitat, macroinvertebrate and fish assemblages in an Iowa stream. In-stream habitat, macroinvertebrates, and fish were sampled from two buffered sites and two unbuffered sites, with the greatest substrate, water depth, and velocity heterogeneity occurring in buffered sites. The highest macroinvertebrate richness (11) as well as fish species richness (14), diversity (1.99) and IBI score (3 7) were found in the site …

Research Plan And Preliminary Results - A Field Research Site For Emerging Contaminants In Iowa, Douglas J. Schnoebelen, Dana W. Kolpin, Larry B. Barber, Edward T. Furlong, Michael M. Meyer, Mary Skopec

Journal of the Iowa Academy of Science: JIAS

Research has recently documented the prevalence of a wide variety of pharmaceuticals and other emerging contaminants (ECs) in streams across the United States. Wastewater treatment plants (WWTPs) have been found to be an important source and collection point of ECs to streams as many ECs are incompletely removed during treatment. To investigate the complex instream processes (e.g., dilution, sorption, degradation, dispersion, etc.) chat can affect ECs following their input from a WWTP and determining if such input is having an effect on the aquatic ecosystem requires the integration of multi-disciplinary efforts at a carefully selected field site. Preliminary work has …

The Honey Creek Member: A New Holocene Alluvial Stratigraphic Unit In The Midwest, Jeremy S. Dillon, Rolfe D. Mandel

Journal of the Iowa Academy of Science: JIAS

This paper describes the type locality and type section for the Honey Creek Member, a stratigraphic unit first recognized in the Honey Creek drainage in southeastern Nebraska. The alluvial chronology for Honey Creek basin is similar to the regional chronology of streams in the Midwest, and all of the formal members of the DeForest Formation occur in the basin. However, the lithology of one unit, the Honey Creek Member, does not correlate with any of the formally recognized members of the DeForest Formation. The Honey Creek Member is composed of grayish brown silt loam overbank facies coarsening downward to a …

Silicification Of Corals, Stromatoporids, And Brachiopods At The Weathered Surface Within The Devonian-Age Little Cedar Formation (Solon And Rapid Members) In Eastern Iowa, Adam L. Majeski, Paul L. Garvin

Journal of the Iowa Academy of Science: JIAS

Diagenesis of fossils contained in middle-Devonian limestones was studied at the Troy Mills and Robins quarries in Linn County, Iowa and at the Four County and Ernst quarries in Johnson County, Iowa. Fossils located at weathered bedrock surfaces were preferentially silicified, and the silicification affected corals, stromatoporids and, to a limited extent, brachiopods, but not other fossils or the host rock. The siliceous horizon extends no more than a few centimeters below the weathered surfaces, suggesting that silicification was constrained by them. Silica for silicification might have come from a variety of sources, including sponge spicules or radiolarian tests, insoluble …

Sl1 Rna Gene Recovery From Enterobius Vermicularis Ancient Dna In Pre-Columbian Human Coprolites, Alena M. Iñiguez, Karl Reinhard, Marcelo Luiz Carvalho Gonçalves, Luiz Fernando Ferreira, Adauto Araújo, Ana Carolina Paulo Vincente

Karl Reinhard Publications

Enterobius vermicularis, pinworm, is one of the most common helminths worldwide, infecting nearly a billion people at all socio-economic levels. In prehistoric populations the paleoparasitological findings show a pinworm homogeneous distribution among hunter-gatherers in North America, intensified with the advent of agriculture. This same increase also occurred in the transition from nomad hunter-gatherers to sedentary farmers in South America, although E. vermicularis infection encompasses only the ancient Andean peoples, with no record among the pre-Colombian populations in the South American lowlands. However, the outline of pinworm paleo epidemiology has been supported by microscopic finding of eggs recovered from coprolites. …

Why Is Maize A Sacred Plant? Social History And Agrarian Change On Sumba, Cynthia Twyford Fowler

Faculty Scholarship

Why has maize, a plant with origins in the New World, become ritually important in an indigenous Southeast Asian religion? While environmental conditions and agricultural economics are key determinants of everyday resource management practices in insular Southeast Asia, it is necessary to consider ethnic identity, political economy, and social structure in order to understand the religious significance of natural resources in contemporary society. Linguistic, cosmological, and horticultural data are combined with an analysis of local perceptions of culture and environment. This information is used to explain the transformation of an introduced plant into an indigenous sacrament. Ethnographic data, including a …

Comparison Of Aquatic Life Depicted In Illustrations And Plaster Casts Of The Punt Relief From The Temple Of Hatshepsut At Deir El-Bahari, Emily Lord, Eugene G. Maurakis

Virginia Journal of Science

The primary objective of this study is to document differences between image characteristics of two sources (illustrations in Naville, 1898; and images in the cast of the relief at Virginia Museum of Fine Arts (VMFA) of the Punt relief from the temple of Hatshepsut at Deir El-Bahri. Our second is to compare cast images to photographs of the original relief. Characteristics of 30 species in the illustrations were described and compared to descriptions of the corresponding 30 species photographed from the cast at VMFA. The number of differences and similarities were recorded for each pair of corresponding icons and used …

The Moths Of Neal Smith National Wildlife Refuge: A Preliminary Assessment, Michelle N. Lewis, Renae M. Steichen, Keith S. Summerville

Journal of the Iowa Academy of Science: JIAS

North American prairie systems are believed to have supported substantial insect biodiversity. Loss of prairie and oak savanna habitats, however, has been severe in many Midwestern states, including Iowa. An unanswered question facing land managers interested in restoring tallgrass prairies to the Iowan landscape is the degree to which restored habitats contain native insect species that are dependent upon prairie habitat. This study reports data from a preliminary survey of the moths of Neal Smith National Wildlife Refuge, a 2,292-ha prairie and oak savanna restoration site in central Iowa. We identified and cataloged a total of 426 species of moths …

Iowa's Sand Prairie State Preserves: Anomalous Grain-Size Distributions And Optically Stimulated Luminescence (Osl) Dates, Steven H. Emerman, Brian R. Depew, Lisa K. Anderson

Journal of the Iowa Academy of Science: JIAS

Grain-size distributions and optically stimulated luminescence (OSL) dates were obtained for the sand from Iowa's five sand prairie state preserves, which are Behren's Ponds and Woodland, Cedar Hills Sand Prairie, Kish-Ke-Kosh Prairie, Marietta Sand Prairie and Rock Island. OSL dates ranged from the late Pleistocene (15,560 years B.P.) to the very late Holocene (as recent as 590 years B.P.), indicating that the late Pleistocene and Holocene Epochs in Iowa have seen multiple episodes of aridity, which is consistent with results from the Nebraska Sand Hills and eolian sand stringers in southeastern Minnesota. The grain-size distributions were anomalous in that, compared …

Letter To The Editor - Conservation Of Freshwater Mussels In Iowa, K. Elizabeth Poole

Journal of the Iowa Academy of Science: JIAS

Freshwater mussels occur in a variety of aquatic ecosystems worldwide but nowhere is mussel species richness as high as is reported in North America. With nearly 300 recorded species in the U.S., mussels are key components of freshwater biodiversity playing a vital role in benthic communities. Ecologically important in biological processing and nutrient cycling, mussels are also an important food item for a variety of mammals including mink, otter, and raccoon. In addition to ecological importance, freshwater mussels have been economically important in the production of cultured pearls.
