Mammal Species Inventory Using Various Trapping Methods In Zone 4 Of Billy Barquedier National Park, Belize During Rainy Season, Mersady Redding Dec 2019

Mammal Species Inventory Using Various Trapping Methods In Zone 4 Of Billy Barquedier National Park, Belize During Rainy Season, Mersady Redding

Animal Science Undergraduate Honors Theses

Belize is a small country, but it is extremely ecologically diverse. Based on the few studies conducted in Belize, the abundance of mammals is low but diversity is high. Particular findings note the number and identity of species differed between four sites in the Maya Mountains of Belize, indicating that a data set from a single site is not representative of the Neotropical region. Insufficient data is available to estimate current species richness of many areas in Belize, including Billy Barquedier National Park (BBNP). The objective of this study was to explore trapping and documentation methods of terrestrial mammals in …


Artful Nature And The Legacy Of Maria Sibylla Merian, Emily N. Roush, Shannon R. Zeltmann, Felicia M. Else, Kay Etheridge, Shannon Egan Oct 2019

Artful Nature And The Legacy Of Maria Sibylla Merian, Emily N. Roush, Shannon R. Zeltmann, Felicia M. Else, Kay Etheridge, Shannon Egan

Schmucker Art Catalogs

The exhibition Artful Nature and the Legacy of Maria Sibylla Merian celebrates the skills and influences of a remarkable woman from seventeenth-century Europe. Curated by Emily Roush ’21 and Shannon Zeltmann ’21 with the guidance of Professors Kay Etheridge (Biology) and Felicia Else (Art History), Emily and Shannon selected the prints, organized them into categories, and carried out research on them, much of which was relatively obscure and would have been challenging even for graduate students.

Maria Sibylla Merian lived and worked in a time of vibrant intersections of art and science in Europe. Her images of insects and plants …


Traffic Noise And Sexual Selection: Studies Of Anthropogenic Impact On Bird Songs And Undergraduate Student Reasoning Of Evolutionary Mechanisms, Sarah Spier Aug 2019

Traffic Noise And Sexual Selection: Studies Of Anthropogenic Impact On Bird Songs And Undergraduate Student Reasoning Of Evolutionary Mechanisms, Sarah Spier

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

Humans have transformed much of the natural landscape and are continuing to do so at an accelerated rate, compromising natural areas that serve as important habitat for many species. Roads impact much of the environment as they fragment habitat and introduce traffic noise into the acoustic environment, deferentially affecting wildlife in roadside habitat. I explored how traffic noise affects the detection of birds based on whether their vocalizations were masked by traffic noise. Masked species detection was not affected by an increase in traffic noise amplitude, while there was a negative effect of traffic noise amplitude on unmasked species detection, …


The Role Of Oxytocin On Social Behavior Associated With The Formation Of A Social Pair-Bond In The Socially Monogamous Convict Cichlid (Amatitlania Nigrofasciata), Christopher Garcia May 2019

The Role Of Oxytocin On Social Behavior Associated With The Formation Of A Social Pair-Bond In The Socially Monogamous Convict Cichlid (Amatitlania Nigrofasciata), Christopher Garcia

Graduate Theses

The mechanisms for monogamy have evolved several times throughout history across various taxa in accordance with selective pressures. In vertebrates, monogamy is facilitated by the formation and the maintenance of social pair-bonds between mates. Social pair-bonds are a form of selective attachment that require complex neurobiological pathways in order to develop and continue. These neurobiological pathways are often regulated by neuroendocrine mechanisms, such as the release of the two neuroendocrine nonapeptides, oxytocin and arginine vasopressin, in specific parts of the brain or body. These neuroendocrine peptides play a big role in social and sexual behaviors. In prairie voles (Microtus ochrogaster) …


Zero Textbook Cost Syllabus For Env 3009/4900 (Conservation Biology And Sustainable Development), Stephen Gosnell Apr 2019

Zero Textbook Cost Syllabus For Env 3009/4900 (Conservation Biology And Sustainable Development), Stephen Gosnell

Open Educational Resources

Conservation biology is an interdisciplinary topic that explores how we can protect and maintain natural areas. Due to the resources we take and impacts we have on natural environments, this field is directly related to restoration ecology (restoring natural areas) and sustainable development/natural resource management. We will explore the basis for these related fields from an ecological, social, legal, and cultural perspective, as all conservation and management projects take place in the larger human landscape. We will consider how we measure biodiversity, why it matters, why is it is threatened, and how we can manage (protect, restore, maintain, use) it …

City Limits: Heat Tolerance Is Influenced By Body Size And Hydration State In An Urban Ant Community, Dustin Jerald Johnson Jan 2019

City Limits: Heat Tolerance Is Influenced By Body Size And Hydration State In An Urban Ant Community, Dustin Jerald Johnson

University of the Pacific Theses and Dissertations

Cities are rapidly expanding, and global warming is intensified in urban environments due to the urban heat island effect. Therefore, urban animals may be particularly susceptible to warming associated with ongoing climate change. Thus, I used a comparative and manipulative approach to test three related hypotheses about the determinants of heat tolerance or critical thermal maximum (CTmax) in urban ants—specifically, that (1) body size, (2) hydration status, and (3) preferred micro-environments influence CTmax. I further tested a fourth hypothesis that native species are particularly physiologically vulnerable in urban environments. I manipulated water access and determined CTmax for 11 species common …


Transgenerational Plasticity Is Sex-Dependent And Persistent In Yellow Moneyflower (Mimulus Guttatus), Kayla Akkerman Jan 2019

Transgenerational Plasticity Is Sex-Dependent And Persistent In Yellow Moneyflower (Mimulus Guttatus), Kayla Akkerman

All Master's Theses

Transgenerational phenotypic plasticity, whereby environmental cues experienced by parents alter the phenotype of their progeny, has now been documented in diverse organisms. Transmission of environmentally determined responses is known to occur through both maternal and paternal gametes, but the underlying mechanisms have rarely been compared. In addition, the persistence of induction over multiple generations appears to vary widely but has been characterized for relatively few systems. Yellow monkeyflower (Mimulus guttatus) is known to exhibit transgenerational induction of increased glandular trichome production in response to simulated insect damage. Here we test for differences between maternal and paternal transmission of …
