At Home And At Large In The Great Plains: Essays And Memories, Paul A. Johnsgard

Zea E-Books Collection

This volume presents fourteen essays (some updated) that originally appeared in Prairie Fire, a monthly free newspaper that for seven years (as of 2015) has carried important messages of social, environmental, and economic issues in a mature and nonpartisan manner to tens of thousands of residents of Nebraska, western Iowa, eastern Colorado, and southern South Dakota, and by mail to subscribers in the rest of the world. These essays discuss the North American east-west ecological boundaries, spring migration events, birds at the bird feeder, feathered survivors of a glacial past, the threatened sharp-tailed grouse of Nebraska and South Dakota, and …

The Influence Of Spines On Predation Of Devonian Brachiopods, Broc S. Kokesh

Undergraduate Research Symposium 2015

Brachiopods are small animals that live on the seafloor and are prominent in the Devonian fossil record from 420 to 360 million years ago. An interesting feature of some species is that large spines develop on their exterior surfaces and are thought to have evolved for defense against predators. Fortunately, this hypothesis can be tested by observing wound marks indicative of attempted predation as described by Zhang et al. (2011). In this study, I examined wound marks on fossils of the spiny brachiopod Atrypa rockfordensis and the spineless Atrypa devoniana. Results show that A. rockfordensis only experienced attacks at …

Ocean Food Systems, Barry A. Costa-Pierce

Marine Sciences Faculty Presentations

Presentation given during session on Food Justice, where Barton Seaver, Director of the Healthy and Sustainable Food Program in the T.H. Chan School of Public Health at Harvard, described a great nutrition and health crisis in America perpetuated by groups demarketing seafood and promoting meat in the American diet. Seaver noted that Americans consume about 167 lbs. of meat a year and only 14 lbs. of seafood, leading to connected public health and environmental crises, heart disease, and obesity.

According to presenter Barry Costa-Pierce:

Seafood systems in the USA are our most insane foods; America imports nearly every seafood we …

Historical Common Names Of Great Plains Plants, With Scientific Names Index. Volume Ii: Scientific Names Index, Elaine Nowick

Zea E-Books Collection

Containing thousands of entries of both vernacular and scientific names of Great Plains plants, the literature that informs this exhaustive listing spans nearly 300 years. Author Elaine Nowick has drawn from sources as diverse as Linnaeus, Lewis and Clark, and local university extension publications to compile the gamut of practical, and often fanciful, common plant names used over the years. Each common name is accompanied by a definitive scientific name with references and authority information. Interspersed with scientifically-correct botanical line drawings, the entries are written in standard ICBN format, making this a useful volume for scholars as well as lay …

Global Warming And Population Responses Among Great Plains Birds, Paul A. Johnsgard

Zea E-Books Collection

Based on an analysis of 47 years (1967–2014) of Audubon Christmas Bird Counts (CBC), evidence for population changes and shifts in early winter (late December) ranges of nearly 150 species of birds in the Great Plains states is summarized, a region defined as including the Dakotas, Nebraska, Kansas, Oklahoma, and the Texas panhandle. The rationale for this study had its origins in Terry Root’s 1988 Atlas of North American Wintering Birds. Root’s landmark study provided a baseline for evaluating the nationwide winter distributions of 253 North American birds in the mid-20th century, using data from the National Audubon Society’s …

Mesa Verde Vegetal Survey, Stanley L. Welsh

Books by Faculty of the Monte L. Bean Life Science Museum

Abstract

This write-up is mainly concerned with plant specimens recovered and examined from major prehistoric cliff dwellings being excavated during the Wetherill Mesa Project. It also includes anecdotes from the author’s experiences in Mesa Verde. An overall summary of the species identified is presented at the end of this work, including suggestions as to how plants may have been used based on modern Native American surveys.

Evolution, Systematics & Geographic Parthenogenesis Of Ilyodromus (Crustacea, Ostracoda), Rylan James Shearn

Theses

Most multicellular organisms reproduce sexually at some point in their life cycle. This is paradoxical because being asexual is theoretically far more advantageous. Asexual organisms do not need to find and court new mates, they reproduce at a faster rate, and with no males, all members of the population contribute toward population growth rate. With over 20, often mutually exclusive hypotheses, this paradox resists a synthesised explanation, and continues to represent one of the largest gaps in our understanding of fundamental evolutionary theory. Clearly, more real world studies are required that document the selective mechanisms underlying differences in evolutionary fitness …

Using The Past To Restore The Future: Quantifying Historical Vegetation To Assist In Tidal Freshwater Wetland Restoration, Christopher D. Gatens

Undergraduate Research Posters

Wetlands have been providing humans with critical natural ecosystem services throughout our time on Earth. Nevertheless, these invaluable ecosystems have been habitually altered as a cost of human progression. Two of the most common alterations to wetlands are damming and filling. Both occurred along Kimages Creek in Charles City County, VA during the 19^th and 20^th centuries. In 2010 the Lake Charles dam was partially removed, restoring the creek’s tidal communication with the James River. Upon the recession of the body of water, numerous woody stumps were revealed. We studied these stump remnants in an attempt to assess …
