This book was released on 2013 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding a species' hierarchical genetic variation may provide insights into its ability to cope with current and future stressors, such as climate change, exploitation, and degradation of habitat. Analyzing the events that led to speciation and population diversification may give a framework for predicting responses and adaptations to future changes, imparting critical information for conservation managers. I resolve the evolutionary history and population genetic patterns of the walleye Sander vitreus using molecular and morphological characters and a variety of analyses, including sequences from three nuclear and three mitochondrial (mt) DNA regions and nine nuclear DNA microsatellite (μsat) loci. Results show that walleye and its sister species the sauger S. canadensis diverged ~15.4 Mya (5.2-27.1 Mya = 95% highest posterior density (HPD)), with modern walleye haplotypes differentiating ~10.6 Mya (6.9-14.3 HPD), when climate changes were occurring across North America. Walleye exhibit significant genetic structure (mean FST mtDNA control region=0.24, μsat=0.10) and substantial genetic diversity (mean control region=0.53, μsat=0.68) across its range, at broad- and fine-scales. Contemporary patterns correspond to a genetic isolation by geographic distance hypothesis, with northern populations reflecting differential contribution from three distinct Pleistocene glacial refugia. Comparisons of historic versus modern samples from Lake Erie reveal that allelic frequencies have changed over ~70 years (mean FST control region=0.26, μsat=0.17), with modern populations having higher diversity (mean control region=0.67, μsat=0.72 vs. control region=0.05, μsat=0.47). Today's higher diversity may be due to population rebounds following closure of the walleye fishery in 1970. Paratypes of the historic blue pike did not differ morphologically or genetically from walleye, indicating that the blue pike was not a separate taxon. Additional fine-scale results within the highly degraded Huron-Erie Corridor reveal the seven spawning groups show a mixture of connectivity and divergence. This study also discerns the effects of habitat augmentation on the genetic structure of walleye spawning groups, finding that populations are distinct and have similar levels of genetic diversity (mean control region=0.73, μsat=0.72). Some genetic exchange occurred at an augmentation site, suggesting that walleye from other locations arrived to spawn on the newly available habitat. Such migration could change the genetic composition of the original spawning group. The results of this dissertation provide insight to the processes that shaped the evolution and population genetic patterns of today's walleye, including past climate change, Pleistocene glaciations, and anthropogenic stressors. Future research identifying the adaptations underlying the genetic diversity and divergence patterns discerned here and their respective genetic contributions to fitness will aid efforts to sustain natural populations in the face of ongoing climate change and other anthropogenic stressors.

Book Synopsis Temporal and Spatial Genetic Consistency of Walleye (Sander Vitreus) Spawning Groups by : Jo Ann Banda
Download or read book Temporal and Spatial Genetic Consistency of Walleye (Sander Vitreus) Spawning Groups written by Jo Ann Banda and published by . This book was released on 2011 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: The population genetic structure of three of the largest walleye spawning groups in Lake Erie is tested for consistency over time and space spanning 14 years, based on nine high-resolution nuclear DNA microsatellite loci. Previous genetic studies focused on a one-time genetic "snapshot", with an earlier study by our laboratory finding that the genetic structure of three Lake Erie spawning groups along the southern shore - Maumee River, Sandusky River, and Van Buren Bay reefs - appeared similar in 2003, whereas most other spawning groups across Lake Erie were genetically distinctive. The present study analyzes the stability of genetic similarity patterns within and among 726 walleye spawning at these three sites across years and age cohorts in 1995, 1998, 2003, 2007, and 2008. Genetic patterns are evaluated using pairwise FST analog and contingency tests, AMOVA partitioning, and Bayesian assignment tests. Results reveal overall year-to-year consistency in genetic structure of walleye spawning at the three sites, with some annual variation in the Van Buren Bay reef group. Greater genetic divergence from the other groups is detected in the Van Buren Bay spawning group, which reflects greater geographic separation. Walleye spawning in the Sandusky and Maumee Rivers are genetically distinguishable from each other when data from all years are combined, which suggests possible sample size effect (i.e., annual sample sizes likely were not large enough to detect their genetic differentiation). No significant differences occur among age cohorts, between the sexes, or among sampling dates within spawning runs. Results demonstrate the importance of sampling over several years of walleye spawning runs in order to resolve fine-scale genetic relationships within an open lake system.

Book Synopsis Genetics of Sex Determination by : R.S. Verma
Download or read book Genetics of Sex Determination written by R.S. Verma and published by Elsevier. This book was released on 1996-04-23 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Genetical Theory of Natural Selection by R.A. Fisher (1930) dictated that sexual dimorphisms may depend upon a single medelian factor. This could be true for some species but his suggestion could not take off the ground as gender in Drosophila is determined by the number of X chromosomes. Technical advances in molecular biology have revived the initial thinking of Fisher and dictate that TDF or SRY genes in humans or Tdy in mice are sex determining genes. The fortuitous findings of XX males and XY female, which are generally termed sex reversal phenomenon, are quite bewildering traits that have caused much amazement concerning the pairing mechanism(s) of the pseudoautosomal regions of human X and Y chromosomes at meiosis. These findings have opened new avenues to explore further the genetic basis of sex determination at the single gene level.The aim of the fourth volume, titled Genetics of Sex Determination is to reflect on the latest advances and future investigative directions, encompassing 10 chapters. Commissioned several distinguished scientists, all pre-eminent authorities in each field to shed their thoughts concisely but epitomise their chapters with an extended bibliography. Obviously, during the past 60 years, the metoric advances are voluminous and to cover every account of genes, chromosomes, and sex in a single volume format would be a herculean task. Therefore, a few specific topics are chosen, which may be of great interest to scientists and clinicians. The seasoned scientists who love to inquire about the role of genes in sex determination should find the original work of these notable contributors very enlightening. This volume is intended for advanced students who want to keep abreast as well as for those who indulge in the search for genes of sex determination.

Book Synopsis Handbook of Molecular Microbial Ecology II by : Frans J. de Bruijn
Download or read book Handbook of Molecular Microbial Ecology II written by Frans J. de Bruijn and published by John Wiley & Sons. This book was released on 2011-09-27 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: The premiere two-volume reference on revelations from studying complex microbial communities in many distinct habitats Metagenomics is an emerging field that has changed the way microbiologists study microorganisms. It involves the genomic analysis of microorganisms by extraction and cloning of DNA from a group of microorganisms, or the direct use of the purified DNA or RNA for sequencing, which allows scientists to bypass the usual protocol of isolating and culturing individual microbial species. This method is now used in laboratories across the globe to study microorganism diversity and for isolating novel medical and industrial compounds. Handbook of Molecular Microbial Ecology is the first comprehensive two-volume reference to cover unculturable microorganisms in a large variety of habitats, which could not previously have been analyzed without metagenomic methodology. It features review articles as well as a large number of case studies, based largely on original publications and written by international experts. This second volume, Metagenomics in Different Habitats, covers such topics as: Viral genomes Metagenomics studies in a variety of habitats, including marine environments and lakes, soil, and human and animal digestive tracts Other habitats, including those involving microbiome diversity in human saliva and functional intestinal metagenomics; diversity of archaea in terrestrial hot springs; and microbial communities living at the surface of building stones Biodegradation Biocatalysts and natural products A special feature of this book is the highlighting of the databases and computer programs used in each study; they are listed along with their sites in order to facilitate the computer-assisted analysis of the vast amount of data generated by metagenomic studies. Such studies in a variety of habitats are described here, which present a large number of different system-dependent approaches in greatly differing habitats. Handbook of Molecular Microbial Ecology II is an invaluable reference for researchers in metagenomics, microbial ecology, microbiology, and environmental microbiology; those working on the Human Microbiome Project; microbial geneticists; and professionals in molecular microbiology and bioinformatics.

Book Synopsis Tree Climbing Robot by : Tin Lun Lam
Download or read book Tree Climbing Robot written by Tin Lun Lam and published by Springer Science & Business Media. This book was released on 2012-03-14 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climbing robot is a challenging research topic that has gained much attention from researchers. Most of the robots reported in the literature are designed to climb on manmade structures, but seldom robots are designed for climbing natural environment such as trees. Trees and manmade structures are very different in nature. It brings different aspects of technical challenges to the robot design. In this book, you can find a collection of the cutting edge technologies in the field of tree-climbing robot and the ways that animals climb. It provides a valuable reference for robot designers to select appropriate climbing methods in designing tree-climbing robots for specific purposes. Based on the study, a novel bio-inspired tree-climbing robot with several breakthrough performances has been developed and presents in this book. It is capable of performing various actions that is impossible in the state-of-the-art tree-climbing robots, such as moving between trunk and branches. This book also proposes several approaches in autonomous tree-climbing, including the sensing methodology, cognition of the environment, path planning and motion planning on both known and unknown environment.
