"Over The River And Through The Woods": An Analysis Of Understory And Canopy Plant Diversity In Urban Riparian Forests, Carlisle R. Evans Peck

Urban Forest Project

As population growth explodes and urban areas expand, studying the ecology of urban areas has become increasingly important. Urban development has been shown to drastically alter native habitats and to severely degrade biodiversity. However, urban landscapes also hold the potential to harbor and support valuable biodiversity especially if managed correctly. We studied the understory herbaceous plant and overstory tree canopy diversity of eight forested ravines in the small cities of Rock Island and Moline IL surrounded by a range of urban development intensity. The goal of the project was to determine whether or not the composition of the plant communities …

Dietary Supplement Labeling: Cognitive Biases, Market Manipulation & Consumer Choice, Michael Mccann

Law Faculty Scholarship

There exists increasing concern that the Dietary Supplements Health and Education Act (DSHEA) has proven ineffective. Much of the concern regards the disparity in legislative treatment between dietary supplements, foods, and pharmaceutical drugs. Namely, while pharmaceutical drugs must undergo years of costly pre-market testing, most supplements, like foods, can immediately enter the market, and only after repeated instances of adverse reactions can the Food and Drug Administration (FDA) remove them. Such a framework appears to belie both consumer expectations and marketing strategies, as supplements tend to be most perceived for their apparent medicinal qualities. This philosophy of waiting for a …

Assessing Perceived And Documented Crop Damage In A Tanzanian Village Impacted By Human-Elephant Conflict (Hec), Rebekah R. Hoffmeier-Karimi, Bruce A. Schulte

Biology Faculty Publications

In sub-Saharan Africa human-wildlife conflict (HWC) is a growing conservation issue and human-elephant conflict (HEC) is of special concern. Crop loss to wildlife comprises a main component of HWC. Deterrent methods for crop loss are numerous and such schemes could be more effective by an improved understanding of how farmers’ perceptions align with actual causes of crop loss. Our objective was to compare the perception by farmers of the causes and extent of crop damage to the measured crop damage in fields of maize (Zea mays) using different deterrent methods. We interviewed agriculturalists in the farming village of Miti Mirefu …

Special Section: The Rise of Health Professions. Over the past decade, the health-care sector added jobs month after month, even when jobs were disappearing elsewhere in the economy. The field is projected to add many more in the coming decade, so it makes sense that the number of students majoring in health-related fields rose sharply. Roughly one in 10 college graduates now gets a health-related degree.

Empathy In Other Apes, Kristin Andrews, Lori Gruen

Sentience Collection

A number of scholars have offered behavioral and physiological arguments in favor of the existence of empathy in other species (see Bekoff & Pierce 2009, Flack & de Waal 2000, Plutchik 1987). While the evidence is compelling, claims about empathy in nonhuman apes face two different challenges. The first challenge comes from a set of empirical findings that suggest great apes are not able to think about other’s beliefs. The argument here is based on a view that empathy is associated with folk psychological understanding of others’ mental states, or mindreading, and the existence of mindreading among the other apes …

“I Am A Vegetarian”: Reflections On A Way Of Being, Kenneth J. Shapiro

Human Health Collection

Employing a qualitative method adapted from phenomenological psychology, the paper presents a socio-psychological portrait of a vegetarian. Descriptives are a product of the author’s reflection on (dialogue with) empirical findings and published personal accounts, interviews, and case studies. The paper provides evidence for the hypothesis that vegetarianism is a way of being. This way of experiencing and living in the world is associated with particular forms of relationship to self, to other animals and nature, and to other people. The achievement of this way of being, particularly in the interpersonal sphere, comprises an initial, a transitional, and a crystallizing phase …

Influence Of Group Size On The Success Of Wolves Hunting Bison, Daniel R. Macnulty, Aimee G. Tallian, Daniel R. Stahler, Douglas W. Smith

Wildland Resources Faculty Publications

An intriguing aspect of social foraging behavior is that large groups are often no better at capturing prey than are small groups, a pattern that has been attributed to diminished cooperation (i.e., free riding) in large groups. Although this suggests the formation of large groups is unrelated to prey capture, little is known about cooperation in large groups that hunt hard-to-catch prey. Here, we used direct observations of Yellowstone wolves (Canis lupus) hunting their most formidable prey, bison (Bison bison), to test the hypothesis that large groups are more cooperative when hunting difficult prey. We quantified the relationship between capture …

Gene Expression Of Components Of The Insulin/Insulin-Like Signaling Pathway In Response To Heat Stress In The Garter Snake, Thamnophis Elegans, Tonia S. Schwartz, Anne M. Bronikowski

Journal of the Iowa Academy of Science: JIAS

The insulin/insulin-like signaling (IIS) pathway is an evolutionary conserved molecular signaling pathway that regulates growth, reproduction, stress resistance, and longevity in response to nutrition and external stress. While the constituents of this pathway and their functions are relatively well understood in laboratory model animals, they have not been explored in many other organisms, with notable exceptions in the fisheries literature. We tested for the gene expression of four key components of this pathway in the garter snake (Thamnophis elegans) liver, and determine how the transcription of these components responds to heat stress. We found that the two insulin-like …

Synchronous Rotation In The Eclipsing Binary 68 Herculis Inferred From Doppler Shifts In Its Spectrum And Light Curve Modeling, Kenneth W. Mclaughlin, Janak Panthi

Journal of the Iowa Academy of Science: JIAS

Our differential photometry of the eclipsing binary 68 Herculis through V- and R-filters shows periodic minima consistent with a previously established period. As a function of its orbital motion, we report spectra over a limited wavelength range encompassing H-alpha 656.3 nm and helium 667.8 nm lines. Doppler shifts of both stars were resolved in H-alpha, while only the more massive star rendered the helium line with Doppler shifts that agree with the radial velocity we derive for it from the H-alpha profile. Sinusoidal curve-fits to the orbital dependence of the radial velocities imply circular orbits for both components, with amplitudes …

Improved Functional Prediction Of Hypothetical Proteins From Listeria Monocytogenes 08-5578, Michael J. Lagier, Brittany Bowman, Kelsey Brend, Katherine Hobbs, Michael Foggia, Mark Mcdaniel

Journal of the Iowa Academy of Science: JIAS

Listeria monocytogenes is a foodborne human pathogen responsible for listerosis. The genomes of several L. monocytogenes strains have been recently sequenced. The genome of L. monocytogenes 08-5578, which was in part responsible for a significant listerosis outbreak in 2008, contains an unexpectedly high percentage of protein-encoding genes (1,927 out of 3,161; 60.96%) autonomously annotated as hypothetical proteins. The aim of this study was to test whether a manual annotation strategy could be used to assign more meaningful functional names to the hypothetical proteins of 08-5578. A holistic, manual gene annotation strategy that utilized sequence homology, cellular localization predictions, structure-based evidence, …

The Role Of An Urban Tallgrass Prairie Remnant In Conservation: A Case Study In Central Iowa (Usa), Jimmie D. Thompson, Deborah Q. Lewis, William R. Norris

Journal of the Iowa Academy of Science: JIAS

Although more than 85% of Iowa (USA) was covered by tallgrass prairie at the time of settlement by Europeans in the early 19th century, less than 0.1% remains. The Richard W. Pohl State Preserve at Ames (IA) High School, surrounded on three sides by structures, roads, and other development, protects 4 ha of tallgrass prairie. The preserve, commonly referred to as Ames High Prairie (AHP), was grazed but never plowed under private ownership until its acquisition by the Ames School District in 1959.

Although considered for development as a parking lot or football field in the 1960s, the residents of …

Linking Rainforest Ecophysiology And Microclimate Through Fusion Of Airborne Lidar And Hyperspectral Imagery, Eben N. Broadbent, Angélica M. Zambrano, Gregory P. Asner, Christopher B. Field, Brad E. Rosenheim, Ty Kennedy-Bowdoin, David E. Knapp, David Burke, Christian Giardina, Susan Cordell

Marine Science Faculty Publications

We develop and validate a high-resolution three-dimensional model of light and air temperature for a tropical forest interior in Hawaii along an elevation gradient varying greatly in structure but maintaining a consistent species composition. Our microclimate models integrate high-resolution airborne waveform light detection and ranging data (LiDAR) and hyperspectral imagery with detailed microclimate measurements. We then use modeled microclimate and forest structural and compositional variables to explain variation in spatially explicit measurements of leaf traits, including gas exchange and structure. Our results highlight the importance of: (1) species differences in leaf traits, with species explaining up to 65% of the …

Trait Evolution In Anseriformes: Is Evolution Of Body Mass, Diet, Locomotory Behavior, And Diel Activity Pattern Correlated?, Zoe M. Kao

Scripps Senior Theses

The morphologies and behaviors of animals evolve and diversify, filling ecological niches in their environments. In this study I examine how a morphological trait, body mass, and three ecological traits, namely diel activity patterns, diving/non-diving locomotion, and diet, evolve in the Anseriformes (waterfowl). Through ancestral state reconstructions using a maximum likelihood approach the evolution of these traits was compared to see if any patterns of trait coevolution emerged. Body mass was compared to each ecological trait using a phylogenetic ANOVA to test if there were body size differences between ecological groups. The pattern of male and female body mass evolution …

The Role Of Landscape Variation In Shaping The Evolutionary Diversification Of Chimpanzees (Pan Troglodytes) In A Biodiversity Hotspot, Matthew William Mitchell

Legacy Theses & Dissertations (2009 - 2024)

In this dissertation, I combine population genetic and demographic history analyses of autosomal, mitochondrial and Y-chromosome genetic markers with spatially explicit modeling techniques to study the biogeographic mechanisms responsible for shaping patterns of genetic diversity among chimpanzees in Cameroon and eastern Nigeria. I also describe a new software tool, TESS Ad-Mixer, that I developed early on in this study to help visualize the geographic distribution of demes recovered from population cluster analyses.

Transdisciplinary Application Of Cross-Scale Resilience, Shana M. Sundstrom, David G. Angeler, Ahjond S. Garmestani, Jorge-H. Garcia, Craig R. Allen

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

The cross-scale resilience model was developed in ecology to explain the emergence of resilience from the distribution of ecological functions within and across scales, and as a tool to assess resilience. We propose that the model and the underlying discontinuity hypothesis are relevant to other complex adaptive systems, and can be used to identify and track changes in system parameters related to resilience. We explain the theory behind the cross-scale resilience model, review the cases where it has been applied to non-ecological systems, and discuss some examples of social-ecological, archaeological/ anthropological, and economic systems where a cross-scale resilience analysis could …

Determinants Of Bite Force In Four Species Of Sharks From The Gulf Of Mexico With An Emphasis On The Atlantic Sharpnose Shark, Rhizoprionodon Terraenovae, Kyle Walter Rice

Electronic Theses and Dissertations

Bite force can provide valuable information regarding the physiological ecology of an organism. However, there have been few studies wherein bite force in sharks has been considered. Herein I report on a study of the bite force of four species of sharks with particular emphasis on that of the atlantic sharpnose shark, rhizoprionodon terraenovae. Among the four species examined, blacktip shark, carcharhinus limbatus bite force was significantly higher than that of sharpnose, rhizoprionodon terraenovae. There was no significant difference between the bite force of those species compared with the same for finetooth shark, c. Isodon and spinner shark, c. Brevipinna. …

The Impact Of Culture & Ethnicity On The Counseling Process: Perspectives Of Genetic Counselors From Minority Ethnic Groups, Brittanie Morris

Theses and Dissertations

In the genetic counseling profession, discussions about cross-cultural counseling and cultural competence emphasize the importance of patient culture as well as counselor culture in a counseling session. A culturally competent counselor should be aware of the influence of her own cultural values on interactions with patients and peers (Weil, 2000; & Uhlmann, Schuette, & Yashar, 2011). Focusing specifically on counselors from cultural/ethnic minorities, this mixed-methods study sought to empirically evaluate the influence of a counselor's cultural values and ethnic identity on the genetic counseling process. 162 genetic counselors, 58 of whom self-identified as being from an ethnic minority group, completed …

Developmental Origins Of Pregnancy Loss In The Adult Female Common Marmoset Monkey (Callithrix Jacchus), J. N. Rutherford, V. A. Demartelly, D. G. Layne Colon, Corinna N. Ross, S. D. Tardif

Biology Faculty Publications (Archived)

Background: The impact of the intrauterine environment on the developmental programming of adult female reproductive success is still poorly understood and potentially underestimated. Litter size variation in a nonhuman primate, the common marmoset monkey (Callithrix jacchus), allows us to model the effects of varying intrauterine environments (e.g. nutrient restriction, exposure to male womb-mates) on the risk of losing fetuses in adulthood. Our previous work has characterized the fetuses of triplet pregnancies as experiencing intrauterine nutritional restriction. Methodology/Principal Findings: We used over a decade of demographic data from the Southwest National Primate Research Center common marmoset colony. We evaluated differences between …

Effects Of Phylogeny On Structural Correlations Of Vertebrate Eyes, Amanda Yl Jacobs

Scripps Senior Theses

Common ancestry prevents scientists from using traditional statistical tests in dimensional comparisons that span entire clades. Data in these cases are non-independent, so a variety of special statistical methods have been developed specifically for phylogenetic comparative analyses. A phylogenetic least squares method was used to re-examine four published datasets detailing structural correlates of eyes while factoring in the different ways the phylogeny was expected to affect the covariance in trait values. All analyses were carried out in a strict phylogenetic context, using published time-calibrated phylogenies and the statistical platform R. Specifically, Pagel’s lambda was used to determine how much of …
