Effects Of Dimethyl Sulfoxide And Glycerol Based Vitrification Protocols On Zona Pellucida Hardening In Mature Bovine Oocytes, 2018 Louisiana State University and Agricultural and Mechanical College
Effects Of Dimethyl Sulfoxide And Glycerol Based Vitrification Protocols On Zona Pellucida Hardening In Mature Bovine Oocytes, Kaci Denise Rogers
LSU Master's Theses
Zona pellucida hardening is a natural process that occurs after oocyte fertilization to prevent polyspermic fertilization and to protect embryonic development. Pre-fertilization hardening of the zona pellucida however, decreases fertilization rates. Cryoprotectants have also been shown to negatively affect fertilization rates, one possible mechanism of which being through zona hardening. This experiment was conducted to determine the effect of different cryoprotectants on hardening of the zona pellucida using fresh mature bovine oocytes and vitrified mature bovine oocytes. Oocytes were post-slaughter from mixed breed cows. After collection, oocytes were randomly assigned to three cryoprotectant treatment groups: dimethyl sulfoxide (DMSO), glycerol or …

Impact Of Environmental Factors On Potential Nest Environment Of The Painted Turtle (Chrysemys Picta), 2018 Elizabethtown College
Impact Of Environmental Factors On Potential Nest Environment Of The Painted Turtle (Chrysemys Picta), Alyssa W. Taylor
Biology: Student Scholarship & Creative Works
The painted turtle (Chrysemys picta) has temperature-dependent sex determination, meaning that the temperature of the nest determines sex. Vegetation cover of nests has been found to affect the hatchling sex ratio, indicating that there is an indirect causal relationship between sex ratio and vegetation cover. This study looked at the relationship between thermal nest environment and environmental variables (nest temperature and soil composition). Simulated turtle nests were created around a lake located on Elizabethtown College’s campus in Elizabethtown, Pennsylvania in locations with varying amounts of cover. A temperature data logger was placed in each nest to record the …
Evaluating Temporal Changes In Landscape Heterogeneity As An Influence On Freshwater Turtle Habitat In Lancaster County, Pennsylvania, 2018 Elizabethtown College
Evaluating Temporal Changes In Landscape Heterogeneity As An Influence On Freshwater Turtle Habitat In Lancaster County, Pennsylvania, Elizabeth Dibiase
Biology: Student Scholarship & Creative Works
Human activity causes landscape changes, which in turn can influence habitat fragmentation and a loss of habitat connectivity. The purpose of this project was to evaluate temporal changes in landscape heterogeneity on potential habitat availability and accessibility for the painted turtle, Chrysemys picta. We hypothesized that the number of freshwater ponds has increased and that the landscape between freshwater ponds has become more heterogeneous from the 1960s to 2016 in Lancaster County, Pennsylvania. We obtained historical wetlands and land use data from the 1950s to 1970s as well as wetlands and land use data from 2011 to 2016 to …

Bird Population Changes Following The Establishment Of A Diverse Stand Of Woody Plants In A Former Crop Field In North Dakota, 1975– 2015, Lawrence D. Igl, Harold A. Kantrud, Wesley Newton
USGS Northern Prairie Wildlife Research Center
Changes in the coverage of trees and shrubs on the North Dakota landscape since Euro- American settlement have likely had a pronounced impact on bird species that favor woody vegetation. Long- term data sets on breeding bird populations in wooded habitats in North Dakota or in the Great Plains are scarce. In 1975 a wildlife habitat plot was established in a 10.5 ha cropland field with a long history of small- grain production. Th e objective of this article is to evaluate the successional changes in bird populations as the habitat at this site became more biologically and structurally complex …

Transcriptomic Response To Immune Challenge In Zebra Finch (Taeniopygia Guttata) Using Rna-Seq, 2018 Western Kentucky University
Transcriptomic Response To Immune Challenge In Zebra Finch (Taeniopygia Guttata) Using Rna-Seq, Cassandra Scalf
Masters Theses & Specialist Projects
Despite the convergence of rapid technological advances in genomics and the maturing field of ecoimmunology, our understanding of the genes that regulate immunity in wild populations is still nascent. Previous work to assess immune function has relied upon relatively crude measures of immunocompetence. However, with next-generation RNA-sequencing, it is now possible to create a profile of gene expression in response to an immune challenge. In this study, captive zebra finch (Taeniopygia guttata; adult males) were challenged with bacterial lipopolysaccharide (2 mg/Kg BW; dissolved in 0.9% saline) or vehicle (0.9% saline) to stimulate the immune system. Two hours after injection, birds …
Assessing Trade-Offs In Large Marine Protected Areas, 2018 Old Dominion University
Assessing Trade-Offs In Large Marine Protected Areas, Tammy E. Davies, Graham Epstein, Stacy E. Aguilera, Cassandra M. Brooks, Michael Cox, Louisa S. Evans, Sara M. Maxwell, Mateja Nenadovic, Natalie C. Ban
Biological Sciences Faculty Publications
Large marine protected areas (LMPAs) are increasingly being established and have a high profile in marine conservation. LMPAs are expected to achieve multiple objectives, and because of their size are postulated to avoid trade-offs that are common in smaller MPAs. However, evaluations across multiple outcomes are lacking. We used a systematic approach to code several social and ecological outcomes of 12 LMPAs. We found evidence of three types of trade-offs: trade-offs between different ecological resources (supply trade-offs); trade-offs between ecological resource conditions and the well-being of resource users (supply-demand trade-offs); and trade-offs between the well-being outcomes of different resource users …

Saving Species, One Individual At A Time: Zoo Veterinarians Between Welfare And Conservation, Irus Braverman
Journal Articles
The role of zoo veterinarians has changed significantly in the last several decades, reflecting and revealing broader transformations in zoo culture, especially among North American accredited zoos. This article draws on several interviews with prominent zoo vets, as well as on regulations that pertain to their work, to highlight their current position at the nexus of animal health and welfare, on the one hand, and of species conservation, on the other hand. The transformation of zoos into conservation institutions in particular has resulted in the vets’ novel focus on the sustainability of populations and their intensified involvement in in situ …

Fishery Interaction Modeling Of Cetacean Bycatch In The California Drift Gillnet Fishery To Inform A Dynamic Ocean Management Tool, 2018 Old Dominion University
Fishery Interaction Modeling Of Cetacean Bycatch In The California Drift Gillnet Fishery To Inform A Dynamic Ocean Management Tool, Nicholas B. Sisson
Biological Sciences Theses & Dissertations
Understanding the drivers that lead to interaction between target species in a fishery and marine mammals is a critical aspect in efforts to reduce bycatch. In the California drift gillnet fishery static management approaches and gear changes have reduced bycatch but neither measure ascertains the underlying dynamics causing bycatch events. To avoid further potentially drastic measures such as hard caps, dynamic management approaches that consider the scales relevant to physical dynamics, animal movement and human use could be implemented. A key component to this approach is determining the factors that lead to fisheries interactions. Using 25 years (1990-2014) of National …
