Demonstration Of Loser Effects In A Novel Crayfish Species, Orconectes Virilis, Stephen C. Meade, Aaron Steele, Daniel A. Bergman Ph.D.

Honors Projects

Agonistic and aggressive behaviors are a common occurrence within crayfish populations in the natural world. These behaviors appear to be very important to individual crayfish in establishment of their social status and in dominance hierarchies that inevitably form within the populations. An important factor in the founding of these hierarchies and an individual’s status within them is the occurrence of winner and loser effects. The winner effect can be defined as the increased probability of an individual winning the next fight after a pervious winning experience. The inverse of this defines the loser effect. The winner effect is a well‐established …

The Construction Of An Elementary Music Curriculum Utilizing Backward Design And Bloom’S Taxonomy, Jessica P. Warner

Senior Honors Theses

Based on the philosophy that the development of curriculum should provide a framework for the assessment of student learning, backward design was utilized to develop a curriculum review for an elementary music program. This design worked directly with three levels of Bloom’s taxonomy (knowledge, application, and synthesis) in order to demonstrate the level of learning for three grades in a small, private mid-Atlantic elementary school. Fifteen students were assessed using the rubrics both before and after curriculum implementation, and analyses were conducted to determine what changes resulted from the focused, short-term curriculum. A plan of improvement was then developed for …

Faith-Based Sexual Education: A Comparison Of Comprehensive And Abstinence-Only Programs, Leanna Fortunato

Master's Theses and Doctoral Dissertations

This study sought to evaluate the effects of faith-based sexual education programs. Participants (ages 13-18, N = 128) were surveyed regarding their religious and sexual attitudes, beliefs, and behaviors prior to completing a sexual education program at their church, synagogue, or religious institution and again after completing the program. The sexual education programs were divided into three groups based on program content and duration: abstinence-only-short, comprehensive-short, and comprehensive-long. The first goal was to assess the within-group effects of attending an abstinence-only or comprehensive sexual education program. Participants from all three groups showed an increase in the degree to which they …

Biomechanical And Morphological Changes In Leaf Abscission Zones During The Ontogeny Of Kalanchoe Pinnatum, Jillian Hodge

Undergraduate Honors Thesis Collection

Kalanchoe pinnatum is able to asexually reproduce with the help of its leaves. In K. pinnatum, embryos are embedded in the notches of a leafs margin. Through the process of abscission, when the plant is disturbed a leaf with embryos falls to the ground and the embryos grow into new plants. Thus, as leaves mature, they face conflicting functional demands to stay on the plant and continue their role in photosynthesis or fall off the plant and asexually reproduce. To examine if there is a point in the leafs development where abscission occurs more readily, I examined breaking strength in …

Behavioral Patterns Of Mustelus Canis (Smooth Dogfish Shark) In A Captive Population, Megan Christine Vaupel

Undergraduate Honors Thesis Collection

Mustelus canis, or the smooth dogfish shark, is the second most common species of shark inhabiting the coastal waters of the Western Atlantic. However little is known about the behavior of this species in the wild and in captivity. In an attempt to establish some data on the behaviors of these animals, I observed a captive population of dogfish at the Indianapolis zoo. I quantified the activity level and distribution of the dogfish in various areas of the exhibit, as well as the frequency and durations of stationary ("resting'') behavior. I analyzed these results in the context of several factors, …

Growth, Larval Development And Metamorphosis In Small-Mouthed Salamanders (Ambystoma Texanum), Nicholas Timothy Zellmer

Undergraduate Honors Thesis Collection

The small-mouthed salamander (Ambystoma texanum), a common species in the midwestern United States, lays its eggs in temporary ponds during mid to late March once they have filled with water from the melting winter snow or early spring rains. For its relative abundance in the Midwest, there is little known about the life history of this species. My research followed the growth of small-mouthed salamander larvae in ponds between hatching, which occurred in early spring (mid-April), and metamorphosis, which occurred in midsummer (early June to mid-July). The research focused on the growth, larval development, and timing of metamorphosis with special …

Development Of A ‘Universal’ Rubric For Assessing Undergraduates’ Scientific Reasoning Skills Using Scientific Writing, Briana Eileen Timmerman, Denise Strickland, Robert L. Johnson, John R. Payne

Faculty Publications

We developed a rubric for measuring students’ ability to reason and write scientifically. The Rubric for Science Writing (Rubric) was tested in a variety of undergraduate biology laboratory courses (total n = 142 laboratory reports) using science graduate students (teaching assistants) as raters. Generalisability analysis indicates that the Rubric provides a reliable measure of students’ abilities (g = 0.85) in these conditions. Comparison of student performance in various biology classes indicated that some scientific skills are more challenging for students to develop than others and identified a number of previously unappreciated gaps in the curriculum. Our findings suggest that use …

Acetylation Of Wrn Protein Regulates Its Stability By Inhibiting Ubiquitination, Kai Li, Rui Wang, Enerlyn Lozada, Wei Fan, David K. Orren, Jianyuan Luo

Toxicology and Cancer Biology Faculty Publications

BACKGROUND: WRN is a multi-functional protein involving DNA replication, recombination and repair. WRN acetylation has been demonstrated playing an important role in response to DNA damage. We previously found that WRN acetylation can regulate its enzymatic activities and nuclear distribution.

METHODOLOGY/PRINCIPAL FINDING: Here, we investigated the factors involved in WRN acetylation and found that CBP and p300 are the only major acetyltransferases for WRN acetylation. We further identified 6 lysine residues in WRN that are subject to acetylation. Interestingly, WRN acetylation can increase its protein stability. SIRT1-mediated deacetylation of WRN reverses this effect. CBP dramatically increases the half-life of wild …

Influence Of Canopy Cover, Nutrients, And Season On Stoichiometric Variation Of Epilithon In Neotropical Streams., Tyler J. Kohler

School of Natural Resources: Dissertations, Theses, and Student Research

Light and nutrient availability are strong factors determining the nutrient composition of epilithon in temperate stream ecosystems. However, little work has been performed regarding this association in tropical streams. In our study, we investigated 1) how gradients of canopy cover and nutrients and 2) wet/dry seasonality influence epilithon standing stocks and nutrient quality. We surveyed 18 stream locations within six watersheds that varied in nutrient and light conditions during both the wet and dry seasons on the island of Trinidad to test these questions. Additionally, we sampled four stream reaches bimonthly for three years, thinning the canopy of two of …

An Assessment Of The Potential Success Of Translocation As A Conservation Strategy For Western Toads (Anaxyrus Boreas) At The Robert J. Bernard Biological Field Station, Maya Higgins

Scripps Senior Theses

In response to imminent habitat destruction at the Robert J. Bernard Biological Field Station (BFS), translocation was assessed as a conservation strategy for a population of Western toads (Anaxyrus boreas). Currently, the BFS is home to a relatively unstudied population of Western toads, which rely on the existence of a seasonal breeding pond in open land owned by Harvey Mudd College on the west side of the field station. Unfortunately, there are plans to develop this plot of land within the next few years and so the breeding pond will be destroyed. In an effort to protect the …

Socio-Environmental And Endocrine Influences On Developmental And Caste-Regulatory Gene Expression In The Eusocial Termite Reticulitermes Flavipes, Matthew R. Tarver, Xuguo Zhou, Michael E. Scharf

Entomology Faculty Publications

BACKGROUND: Strict regulation of caste differentiation, at the molecular level, is thought to be important to maintain social structure in insect societies. Previously, a number of extrinsic and intrinsic factors have been shown to influence caste composition in termite colonies. One important factor is the influence of nestmates; in particular, soldier termites are known to inhibit hormone-dependent worker-to-soldier differentiation. However, soldier influences on nestmates at the molecular level are virtually unknown. Here, to test the hypothesis that soldiers can influence nestmate gene expression, we investigated the impact of four treatments on whole-body gene expression in totipotent Reticulitermes flavipes workers: (i) …

A Numerical Method For Estimating The Variance Of Age At Maximum Growth Rate In Growth Models, Semhar Ogbagaber

Theses and Dissertations

Most studies on maturation and body composition using the Fels Longitudinal data mention peak height velocity (PHV) as an important outcome measure. The PHV is often derived from growth models such as the triple logistic model fitted to the stature (height) data. The age at PHV is sometimes ordinalized to designate an individual as an early, average or late maturer. In theory, age at PHV is the age at which the rate of growth reaches the maximum. Theoretically, for a well behaved growth function, this could be obtained by setting the second derivative of the growth function to zero and …
