Book Synopsis Estimating the Effective Number of Breeders of Brook Trout, Salvelinus Fontinalis, Over Multiple Generations in Two Stream Systems by : Matthew R. Cembrola

Cembrola and published by . This book was released on 2014 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of genetic markers in monitoring populations has become increasingly important for conservation purposes, and can take many forms. While effective population size (Ne) is of great interest to conservation genetics, it may be much easier and more practical to estimate the effective number of breeders (Nb) per cohort as a tool for genetic monitoring of populations. Few studies have estimated Nb for the same species over long periods of time in comparison with demographic or environmental variables. I estimated Nb of the eastern brook trout, Salvelinus fontinalis, as part of long-term studies of two stream systems: West Brook (WB) in Massachusetts and Stanley Brook (SB) in Maine. I used eight microsatellite loci for all available young of the year (YOY) from each cohort in WB and a random subset of YOY distributed evenly throughout SB to obtain genetic-based estimates. I estimated adult abundance (NC) from mark-recapture data, and used seasonal stream flow as an environmental variable. I performed linear models with Nb as the response variable and family structure (number of families and variance in family size), NC, and seasonal stream flow as predictor variables. I found that both the number of families and variance in family size had a strong influence on Nb. Compared to abundance of adults and YOY, Nb was relatively stable over time.Stream flow in both autumn and spring showed a quadratic relationship with Nb in WB, suggesting that intermediate flows are optimal for maintaining a higher Nb. SB, with fewer years of data, did not show these relationships. If incorporated into monitoring programs, Nb can be a useful tool for detecting changes in population status and for informing management decisions.

Book Synopsis Assessing Populations of Eastern Brook Trout (Salvelinus Fontinalis) Above and Below Waterfalls in Mountain Streams of Virginia by :
Download or read book Assessing Populations of Eastern Brook Trout (Salvelinus Fontinalis) Above and Below Waterfalls in Mountain Streams of Virginia written by and published by . This book was released on 2019 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anthropogenically driven factors, such as increasing temperature and sediment in valley streams, acidification of mountain streams, and the introduction of non-native trout, are restricting habitat suitable for healthy populations of eastern brook trout (Salvelinus fontinalis) throughout their native Appalachian range. Brook trout are important as predators of insects in mountain streams and as a favorite of anglers. It is crucial that remaining populations in sustainable habitats be identified and preserved. Waterfalls are geologic knickpoints preventing base-level lowering that create unique, stable landscapes above them, which may alleviate the temperature-productivity/acidity "habitat squeeze" for populations of brook trout and could serve as potentially ideal targets for conservation efforts despite being isolated. This study investigates brook trout occurrence above waterfalls in Virginia and compares brook trout populations found above waterfalls to those below them. One-hundred meter reaches above and below seven waterfalls in Virginia's George Washington and Jefferson National Forest were sampled for brook trout via 3-pass, block-netted, backpack electrofishing depletions. All brook trout were counted, weighed, and measured for fork length. The response variables are differences in 1) percent dominance, 2) population size, 3) biomass, and 4) length-weight index (Fulton's Condition Factor) between brook trout above and below waterfalls. Brook trout dominance (100 vs. 36.9%) is greater above than below waterfalls, but not significantly (p = 0.1003). We found abundance (26 vs.12 individuals per 100m) and overall biomass (885.3 vs 284.6 grams per 100m) of brook trout populations above waterfalls to be significantly greater than their below waterfall counterparts (p = 0.078 for both). We also found brook trout above waterfalls to have a higher condition factor (1.086g/cm3 vs 1.0636g/cm3) than those below waterfalls (p = 0.031). Lastly, we found populations above waterfalls where their occurrence was previously unknown. Despite being isolated, brook trout populations above waterfalls were just as if not more robust than those below and may be excellent targets for conservation.

Book Synopsis Electrophoretic and Isoelectric Focusing Techniques in Fisheries Management by : Donald H. Whitmore
Download or read book Electrophoretic and Isoelectric Focusing Techniques in Fisheries Management written by Donald H. Whitmore and published by CRC Press. 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.

This book was released on 2008 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrologic processes impact the functioning of aquatic ecosystems and influence fish population dynamics. The flow regime of a stream affects the structure, composition, and productivity of fish communities by regulating abiotic habitat conditions and biotic community processes. In the Great Smoky Mountains National Park (GRSM), native brook trout (Salvelinus fontinalis) populations have declined in some watersheds over the past decade, believed to be primarily due to episodic acidification. The potential affects long-term hydrologic patterns, temporal hydrologic trends, and hydrologic extremes have on brook and rainbow trout (Oncorhynchus mykiss) populations were explored in this study. The current GRSM fish sampling program began nearly two decades ago; a total of 69 streams, including 369 sites, are routinely sampled by GRSM fisheries biologists with standard methods. Detailed data is collected on the trout populations. The Nature Conservancy's Indicators of Hydrologic Alteration (IHA) was used to quantify the flow regime of each stream into 67 ecological relevant parameters. Because the trout sites were located in remote ungaged streams, the Hydrologic Simulation Program FORTRAN (HSPF) was used to simulate flows at each trout site for a study period lasting 18 years (1990-2007). Using local climate data the model was calibrated by adjusting parameters including storage, infiltration, runoff, and ground water for three elevation classes (low
