Available in PDF, EPUB and Kindle. Book excerpt: The striped bass (Morone saxatilis) is an anadromous fish distributed along the eastern coast of North America that currently supports one of the most lucrative and important commercial and recreational fisheries in the region. Since the recovery of the Atlantic stock after a collapse in the late 1970s, studies have focused on understanding the connectivity of major spawning grounds and improving methods of abundance estimation. Studies support strong site fidelity of striped bass to major estuaries along the Atlantic coast, but there has been disagreement about connectivity within the largest spawning ground, the Chesapeake Bay. Additionally, no estimates exist for striped bass abundance within the Chesapeake Bay. The objectives of my thesis were to examine the fine scale genetic population structure of striped bass within the lower Chesapeake Bay, and to test the feasibility of a novel, fishery-independent molecular methodology, close-kinship mark-recapture analysis (CKMR), to estimate spawning adult abundance within the Rappahannock River. Sampling of 1,132 adult striped bass and 389 young-of-year (YOY) striped bass was done during the 2016 and 2017 spawning seasons on major spawning grounds of the James, Mattaponi, and Rappahannock rivers. Twenty microsatellite loci were used to examine both the spatial genetic heterogeneity among the river systems and the temporal heterogeneity between sampling years within a river. Significant population pairwise FST values were recovered from 18 of the 21 pairwise comparisons. However, mean FST values between temporal comparisons were higher than those among spatial comparisons, suggesting a lack of biologically meaningful population structure among rivers. Additional analyses and a 30-year tagging data set also support a rate of connectivity among the major rivers high enough to maintain similar allele frequencies. Combined, the data support one genetic stock of striped bass within the lower Chesapeake Bay. The same suite of markers was then used to test the feasibility of CKMR to estimate adult abundance of striped bass within the Rappahannock River system. Using existing sampling programs, 371 spawning adults and 389 YOY were collected on the spawning and nursey grounds of the Rappahannock River in 2016. These samples yielded 2 parent-offspring pairs, resulting in an abundance estimate of 145,081 adult spawning striped bass. Additional analyses indicated that a relatively precise estimate (recovery of 50 POPs) would be made if sample sizes totaled 850 adults and 850 YOY. CKMR can be a feasible option of abundance estimation for striped bass. Overall, my study has provided the first estimate of abundance for Chesapeake Bay striped bass, and has provided strong support of a single, spawning stock of striped bass within the Chesapeake Bay.

Available in PDF, EPUB and Kindle. Book excerpt: The advent of next-generation sequencing technologies has revolutionized the field of molecular ecology, facilitating increasingly fine-scale detection of genetic differences among populations and adaptationally significant mutations. In this thesis, I use genomics to advance solve longstanding mysteries of Striped Bass genetics and lay the groundwork for future studies. In the first chapter, I characterize a group of Striped Bass that were thought to be extirpated in the Saint John River, but likely survive as a remnant population. In the second chapter, I investigate connectivity and relatedness of Striped Bass populations more widely across their native range on the North American Atlantic Coast. I found that Gulf of St. Lawrence, Shubenacadie River, and Saint John River populations were all very distinct from each other and from US populations. US Striped Bass, however, could be separated into three major regions: Hudson River-Kennebec River, Chesapeake Bay-Delaware River, and Roanoke River-Cape Fear River. Demonstrating that this work is useful for management, my SNP loci were able to assign 99% of Striped Bass to these six regions, the first time Roanoke River Striped Bass have been reliably distinguished from Chesapeake Bay bass. Additionally, the presence of apparent US-origin Striped Bass on the northeastern coast of Nova Scotia raises important questions about movement patterns of Striped Bass in this area and highlights the importance of further study. In the third chapter, I used computer modelling simulations to assess the performance of four recent techniques used to find associations between phenotypes and genotypes. I found that Random Forest algorithm with population correction performed similarly to a recent, complex model implemented in confounder adjusted multiple testing. Finally, in chapter four I created 9 novel tools and used them to create an automated text-mining pipeline that can scan full-text articles and extract sentences that contain associations between genes and ecological variables. This pipeline is the first step toward improving genome annotations of non-model organisms such as Striped Bass. Together, these four chapters lay important groundwork for future genomic research both for Striped Bass and other ecologically important species.

Available in PDF, EPUB and Kindle. Book excerpt: Molecular Environmental Biology is the first book to illustrate molecular biological approaches to major issues in environmental biology. International experts have contributed representative chapters that cover how molecular methods and concepts apply to wildlife management, ecology, pollution control and remediation, and environmental health. Specific topics discussed include the use of molecular techniques in the population biology of wild animals and in the management of fisheries, bioremediation, cloning and characterization of the genes responsible for degradation of PCBs and related environmental pollutants, molecular analysis of aromatic hydrocarbon degradation by soil bacteria, and molecular biological techniques in assessing environmental damage to natural habitats. The book also explores how new molecular approaches can be applied to human disease etiology and epidemiology. Topics discussed in this area include an introduction to molecular epidemiology, the uses of molecular biological markers in cancer risk assessment, specific environmental carcinogens found in foods, measuring DNA adducts and mutation frequencies to assess environmental toxic exposures and effect, and using the extent of gene inducibility as a dosimeter of toxic exposure. This book will interest researchers and students in all fields of environmental biology and environmental medicine. Readers will find information on new techniques and applications of established molecular methodology that will stimulate new research ideas, collaborations, and progress. Researchers will now have a chance to make rapid progress on environmental questions that were previously not even open for exploration.

This book was released on 1990-09-24 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: Probably the most ubiquitous biochemical method used today for examining the genetics of individuals, populations, or phylogenetic relationships between taxa is electrophoresis. This book has been created to offer a viewpoint regarding current electrophoretic separation methodologies of macromolecules and their major applications to fisheries management. The chapters in this book have been selected and organized into three sections to create a carefully blended mixture of methodologies and applications designed to educate the novice, as well as stimulate interest in professional researchers currently using electrophoresis for their work. The first section includes chapters that discuss the principles that explain the genetic basis of multiple molecular forms of proteins, the theory and practice of DNA analyses, and the methodology of electrophoretic separation of these macromolecules; starch gel electrophoresis as the predominant electrophoretic tool for fisheries genetics; and protein isoelectric focusing and DNA analysis. The second section describes a variety of applications for electrophoretic techniques. The third section presents a discussion and results of experiments conducted by Dennis Powers and his associates regarding the physiological significance of multiple forms of enzymes using the fish Fundulus heteroclitus as a model system. The book features a catalog of nearly 100 enzyme staining recipes and covers new areas in electrophoretic work, such as DNA fingerprinting, genetic tags, mitochondrial DNA methodologies, and genomic manipulation of fish stocks. This book will provide a useful reference resource for fisheries biologists at federal, state, and local levels; fisheries researchers at universities; and students pursuing degrees involving research in fish genetics.
