Postweaning Skull Growth In Living Didelphid Marsupials: The Case Of Gracilinanus Agilis And Cryptonanus Chacoensis, Iveth A. Villalobos Guerrero, Noé U. De La Sancha

DePaul Discoveries

Ontogeny is described as the history of an organism through its lifetime including development, growth, and allometry. The ontogenetic approach in cranial dimensions has proved useful in interpreting evolutionary patterns. Among the largest Didelphidae family of Neotropical marsupials, the species of Gracilinanus agilis and Cryptonanus chacoensis are poorly known. In this study, we address three questions; Is there sexual dimorphism in these species? What is the pattern of allometry? Which allometric patterns best describe the patterns in the skull and mandible? We applied geometric morphometrics to describe and test these differences using MorphoJ. A discriminant function analysis was performed to …

The Impacts Of Urbanization On Soil: The Effect On Decomposition Rates And Microbial Communities, Maximus C. Halekakis

DePaul Discoveries

The anthropogenic impacts of industrialization have left many ecosystems polluted. Soil, being an imperative actor for ecosystem functions, is important to observe under anthropogenic change. My study examined soil organic matter decomposition, microbial biomass carbon(MBC) and the fungal to bacteria ratio(F:B) across an urban-suburban-exurban landuse gradient in San Luis Obispo, California. A cotton strip assay as well as microBIOMETER® testing was performed on three geographic locations in and outside of the city. The cotton strip decomposition acts as an indicator for organic matter breakdown as microorganisms break down the cellulose in the strips causing them to lose mass and tensile …

Disentangling Drivers Of Metacommunity Structure For Small Mammals Throughout Paraguay, William T. Szromba

DePaul Discoveries

Paraguay is home to a unique precipitation gradient, receiving progressively more precipitation from east to west. It has previously been suggested that metacommunity structures for order Chiroptera assemble along precipitation gradients such as this one. Metacommunities have also been shown to assemble along other bioclimatic gradients such as temperature. This study seeks to expand upon other findings by using a larger dataset, partitioned bioclimatic variables, and more mammalian orders. It also seeks to determine how metacommunities assemble along this gradient in Paraguay, investigate the differences between different ecological metacommunity assemblages, and to further understand which bioclimatic variables have the greatest …

Everyday Exposure: A Qualitative Study Of The Impact Of Gun Violence On The Lives Of Depaul Students, Sara Johnson, Hannah Tariq, Jessica Jerome

DePaul Discoveries

This study examined a novel data source: the contents of letters that students wrote to local, state, or national politicians about gun control for a class assignment in order to collect evidence of the impact of direct and indirect gun violence on the lives of DePaul students. For the study, we coded and analyzed 83 de-identified student letters for themes pertaining to the experience of exposure to gun violence and mass shootings. Our findings include a high prevalence of student exposure to direct incidences of gun violence; strong negative emotions surrounding the fear of gun violence intruding into students’ daily …

Increasing The B-Chromatic Number Of Complete Bipartites By Deleting Edges, Daniel Gawel

DePaul Discoveries

A b-coloring of a graph, G=〈V,E〉, is a proper coloring in which each color has at least one vertex that is adjacent to every other color. The b-chromatic number for G, denoted φ(G), is the largest number of colors you can use to make a b-coloring. For most graphs, φ(G), is around the m-index, an upper bound for φ(G) based on the graph's degree sequence. However, for the complete bipartite graph K_m,n, φ(K_m,n)=2 even though the m-index can be arbitrarily large. In this paper …

Exploring Total Graphs Of Complete Bipartite Graphs, Dominic L J Morgan

DePaul Discoveries

In a proper vertex coloring for a graph G, we call a vertex a b-vertex whenever this vertex is adjacent to at least one vertex of every color class. The b-chromatic number of a graph is defined to be the greatest integer k such that there exists a proper coloring on the graph with k colors where there is at least one b-vertex in every color class. This paper is on the b-chromatic number of the total graphs of complete bipartite graphs. We find bounds of the b-chromatic number for the total graphs of complete bipartite graphs and provide …

The B-Chromatic Number Of Super Cycles, Blair E. Johnson

DePaul Discoveries

The b-chromatic number, a characteristic studied in graph theory, was introduced less than 25 years ago, and while some statistics have been gathered of its properties, the b-chromatic number has yet to be explored in many graphs and circumstances. Before the Undergraduate Summer Research Program, I had no exposure to graph theory, let alone b-colorings. Throughout the program, I developed a fundamental understanding of the subject and began to pursue my own research inquiries. While this objective was difficult to attain at the beginning, I learned strategies and methods to hone my ability to delve into different graphs, and soon …

B-Chromatic Number Of The Graph Power Of The Star Graph, Erik Dahlen

DePaul Discoveries

In this paper we focus on the newly introduced b-colorings of a graph G. A b-coloring is a proper coloring such that for each color class, there exists at least one vertex which is adjacent to every other color. The b-chromatic number of a graph G is the largest number k such that G admits a b-coloring with k colors. This paper will introduce the b-chromatic number of some interesting graphs. Several operations of graphs are defined, and the b-chromatic number of those operations are found. All graphs in this paper are simple, connected, …

Human Second Metacarpal Nanocrystal Analysis, William Abramovich

DePaul Discoveries

Female human bones dated to the 6^th - 8^th century CE were uncovered in Greding Germany after archaeologists discovered a medieval cemetery. Age-at-death estimates have been determined, and data from several techniques are currently being analyzed to learn more about these samples. The purpose of this project is to study the diaphyses of the second metacarpal (mc2) bones excavated using wide-angle x-ray scattering data collected at beamline 1-ID of the Advanced Photon Source at Argonne National Laboratory. The diffraction data were refined using the Rietveld method to obtain lattice (‘a’ and ‘c’) parameter values …

Framing The Path To Fitness: Age Differences In Response To Framed Exercise Messages, Iliya Sherif, David B. Taullahu, Alyssa R. Minton, Joseph A. Mikels

DePaul Discoveries

Physical activity is one of the most protective health behaviors one can engage in, yet 75% of active adults in the US, meaning those who exercise regularly, fall short of the recommended levels of physical activity, with an even greater percentage of older adults living inactive lives, meaning they exercise minimally and engage in prolonged sedentary behavior (CDC, 2019). The goal of the current study was to explore different types of message framing targeted at encouraging older and younger adults to exercise. We recruited older adults (n = 184; Mage = 69.45 years, age range: 65- 80 years) and younger …

Developing A Connection To Nature: The Role Of Pet Ownership In Childhood, Alexia Barrable, Samantha Friedman

People and Animals: The International Journal of Research and Practice

Connection to nature is associated with a range of benefits to well-being in both childhood and adulthood. Childhood experiences seem to play a big role in how adult nature connection develops. Among the many predictors of higher connection to nature, relationships with animals, including pets, likely play an important role in facilitating feelings of closeness with nature. In this paper we present two survey studies, one of children (n = 64, age = 6–16 years) and one of adults (n = 356, age = 18–80 years). Our aim was to find out if children who own pets have …
