Accumulation And Transmission Dynamics Of A Naturally-Occurring Mtdna Deletion In Caenorhabditis Briggsae, Jennifer Anne Sullins

Dissertations and Theses

Maintaining mitochondrial genome sequence integrity is essential for preserving normal mitochondrial function. Several human diseases have been associated with heteroplasmic mitochondrial genome mutations, but few genetic systems can simultaneously represent pathogenic mitochondrial genome evolution and inheritance. The nematode Caenorhabditis briggsae is one such model. Natural C. briggsae isolates are globally-distributed and phylogenetically grouped into three distinct clades, with isolates exhibiting varying levels of a large-scale mtDNA deletion, nad5∆. Furthermore, a small subset of clade II isolates exhibits putative compensatory mutations that may reduce the risk of deletion formation and accumulation in those populations. In this thesis, the author characterizes the …

Climate Change Adaptation Strategies And Approaches For Outdoor Recreation, Daniel O'Toole, Leslie A. Brandt, Maria K. Janowiak, Danielle Shannon, Patricia Leopold, Stephen D. Handler, Et Al.

Michigan Tech Publications, Part 1

Climate change will alter opportunities and demand for outdoor recreation through altered winter weather conditions and season length, climate-driven changes in user preferences, and damage to recreational infrastructure, among other factors. To ensure that outdoor recreation remains sustainable in the face of these challenges, natural resource managers may need to adapt their recreation management. One of the major challenges of adapting recreation to climate change is translating broad concepts into specific, tangible actions. Using a combination of in-depth interviews of recreational managers and a review of peer-reviewed literature and government reports, we developed a synthesis of impacts, strategies, and approaches, …

Can A Global Fund Help Solve The Global Marine Plastic Debris Problem?, Karen Raubenheimer, Alistair Mcilgorm

Journal of Ocean and Coastal Economics

The problem of marine plastic debris impacts all of the world’s oceans and requires all nations to respond. However, developing States require funds to improve waste management infrastructure and services in order to reduce marine debris at source. Plastics manufacturers and retailers globally must be incentivised to design products for the environment as well as for the collection and end-of-life treatment facilities available within the intended markets. Given the oceans are a global common, we investigate the option of developing a global fund mechanism to progress the necessary actions to reduce plastic waste entering the world’s oceans. This requires consideration …

Species Richness, Diversity, And Abundance Of Sponge Communities In Broward County, Florida, 2000-2015, Jessica Price

HCNSO Student Theses and Dissertations

Sponges (Porifera) are a major component of coral reef ecosystems. They outnumber coral species on the Florida Reef Tract, and in places, account for more living cover. Because coral reefs are a vital part of Florida’s economy, it is important to understand how local sponge assemblages vary spatially and temporally, especially as corals continue to decline. However, long-term observations of sponge assemblages (species richness, diversity and abundance) are lacking. To address this, annual photoquadrats were analyzed from a series of 25 sites off Broward County between 2000 and 2015. Variations in sponge assemblages were then compared to several natural and …

Peruvian Pinnipeds As Archivists Of Enso Effects, Mickie Rae Edwards

HCNSO Student Theses and Dissertations

Environmental fluctuations in the eastern Pacific Ocean are reflected in the tissues of some of its most vulnerable apex predators, the Peruvian fur seal (PFS) Arctocephalus australis ssp.and the South American sea lion (SASL) Otaria byronia.These large pinnipeds live in sympatry along the Pacific coastline of South America and forage within the neritic waters over the continental shelf. The coastal waters off Peru are a region of great environmental fluctuations due to periodic, oscillating El Niño- La Niña- Southern Oscillation (ENSO) events, which result in ecosystem-wide food web changes. Pinniped vibrissae (whiskers) are continuously growing keratinous tissues and …

Articles, Abstracts, and Reports

The 2017 Dagstuhl Seminar on Computational Proteomics provided an opportunity for a broad discussion on the current state and future directions of the generation and use of peptide tandem mass spectrometry spectral libraries. Their use in proteomics is growing slowly, but there are multiple challenges in the field that must be addressed to further increase the adoption of spectral libraries and related techniques. The primary bottlenecks are the paucity of high quality and comprehensive libraries and the general difficulty of adopting spectral library searching into existing workflows. There are several existing spectral library formats, but none captures a satisfactory level …

Flexible And Fast Mapping Of Peptides To A Proteome With Proteomapper., Luis Mendoza, Eric W Deutsch, Zhi Sun, David S Campbell, David Shteynberg, Robert L Moritz

Articles, Abstracts, and Reports

Bottom-up proteomics relies on the proteolytic or chemical cleavage of proteins into peptides, the identification of those peptides via mass spectrometry, and the mapping of the identified peptides back to the reference proteome to infer which possible proteins are identified. Reliable mapping of peptides to proteins still poses substantial challenges when considering similar proteins, protein families, splice isoforms, sequence variation, and possible residue mass modifications, combined with an imperfect and incomplete understanding of the proteome. The ProteoMapper tool enables a comprehensive and rapid mapping of peptides to a reference proteome. The indexer component creates a segmented index for an input …

Reproductive Life History And Shell Shape Variation Of Three Species Of Elimia (Pleuroceridae) In The Lower Etowah River Basin, Ellen Winant

Master of Science in Integrative Biology Theses

Pleurocerid snail diversity in the Southeastern United States is thought to be high, but estimates of overall diversity are compromised by uncertain taxonomy. This is particularly true for the genus Elimia, where reliance on conchological characters described by early naturalists for species designation failed to recognize significant variability in shell morphology. In this study we examine three putative species of Elimia to determine if quantifiable conchological characters are associated with differences in life history characteristics. Individuals of E. modesta, E. carinocostata, and E. cariniferawere collected from nine sites in three streams in the lower Etowah River …

Macromolecular-Clustered Facial Amphiphilic Antimicrobials, Md Anisur Rahman, Marpe Bam, Edgar Luat, Moumita Sharmin Jui, Mitra S. Ganewatta, Tinom Shokfai, Mitzi Nagarkatti, Alan W. Decho

Faculty Publications

Bacterial infections and antibiotic resistance, particularly by Gram-negative pathogens, have become a global healthcare crisis. We report the design of a class of cationic antimicrobial polymers that cluster local facial amphiphilicity from repeating units to enhance interactions with bacterial membranes without requiring a globally conformational arrangement associated with highly unfavorable entropic loss. This concept of macromolecular architectures is demonstrated with a series of multicyclic natural product-based cationic polymers. We have shown that cholic acid derivatives with three charged head groups are more potent and selective than lithocholic and deoxycholic counterparts, particularly against Gram-negative bacteria. This is ascribed to the formation …

Modeling The Effect Of Post-Dispersal Seed Predation On Tropical Tree Species In Panama, Justin Tirrell

Fall Student Research Symposium 2018

Palm trees provide a unique opportunity to study what conditions optimize the probability that a seed will grow successfully. The seeds of palm trees, endocarps, are large and easy to locate. When they don't grow, predators leave marks on them that tell the story of their fate. The focus of my experiment is to determine how the current distribution pattern of parent palm trees in Panama Palm trees affects the the future distribution of seedlings. I have programmed a versatile model that takes the assumption that bruchid beetles are the sole predators acting on the seeds, and that these fall …
