Book Synopsis A Molecular Genetic Analysis of Hybridization Between Two Species of Deer (Odocoileus) in Western Canada by : Glenys Anne Hughes
Download or read book A Molecular Genetic Analysis of Hybridization Between Two Species of Deer (Odocoileus) in Western Canada written by Glenys Anne Hughes and published by . This book was released on 1992 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Hybridization between two species of deer (Odocoileus) in western Canada has been postulated for many years. Mitochondrial and nuclear components of the genomes of deer from this and other regions in North America were analyzed to test whether these deer constitute reproductively isolated species or whether interspecies genetic exchange has occurred by hybridization. -- The polymerase chain reaction (PCR) was used to amplify a 359 base pair fragment of the mitochondrial cytochrome b gene from 81 white-tailed deer (O. virginianus), mule deer (O. hemionus hemionus), and Sitka black-tailed deer (O. hemionus sitkensis). Direct DNA sequencing of a 302 base pair block of the PCR-amplified products revealed 34 variable nucleotide positions. These variants define 13 distinct mitochondrial DNA (mtDNA) sequence genotypes. Twelve of these are confined to one or the other species: five genotypes were found only in white-tailed deer and seven only in mule deer or black-tailed deer. In only one instance is a genotype shared between species: a single deer that had been identified as a mule deer possessed a white-tailed deer-type mtDNA. -- Allelic variants at the albumin locus also distinguish the two species. Of 53 animals sampled from British Columbia, Alberta, and Saskatchewan, 25 white-tailed deer and 27 mule deer were homozygous for slow and fast albumin alleles, respectively. Only one animal showed the heterozygote albumin pattern characteristic of hybrid deer. This individual is the same mule deer that possessed an mtDNA genotype found otherwise only in white-tailed deer. -- These data suggest there is little genetic introgression between mule deer and white-tailed deer in western Canada. Similar findings have been reported for Odocoileus in Montana, but high levels of hybridization have been documented between the same species in west Texas. Habitat disturbance and mating behaviour are factors that may affect the frequency and direction of hybridization in different localities. -- Phenetic and cladistic analyses of sequence differences among white-tailed deer, mule deer, and black-tailed deer reveal a discordance between mtDNA genotype and species affinity. Interspecies hybridization, random phylogenetic sorting of mtDNA lineages, and differential rate of mtDNA evolution are considered as hypotheses to explain the relationships among mtDNA genotypes of these species.
Book Synopsis The Evaluation of Forensic DNA Evidence by : National Research Council
Download or read book The Evaluation of Forensic DNA Evidence written by National Research Council and published by National Academies Press. This book was released on 1996-12-12 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1992 the National Research Council issued DNA Technology in Forensic Science, a book that documented the state of the art in this emerging field. Recently, this volume was brought to worldwide attention in the murder trial of celebrity O. J. Simpson. The Evaluation of Forensic DNA Evidence reports on developments in population genetics and statistics since the original volume was published. The committee comments on statements in the original book that proved controversial or that have been misapplied in the courts. This volume offers recommendations for handling DNA samples, performing calculations, and other aspects of using DNA as a forensic toolâ€"modifying some recommendations presented in the 1992 volume. The update addresses two major areas: Determination of DNA profiles. The committee considers how laboratory errors (particularly false matches) can arise, how errors might be reduced, and how to take into account the fact that the error rate can never be reduced to zero. Interpretation of a finding that the DNA profile of a suspect or victim matches the evidence DNA. The committee addresses controversies in population genetics, exploring the problems that arise from the mixture of groups and subgroups in the American population and how this substructure can be accounted for in calculating frequencies. This volume examines statistical issues in interpreting frequencies as probabilities, including adjustments when a suspect is found through a database search. The committee includes a detailed discussion of what its recommendations would mean in the courtroom, with numerous case citations. By resolving several remaining issues in the evaluation of this increasingly important area of forensic evidence, this technical update will be important to forensic scientists and population geneticistsâ€"and helpful to attorneys, judges, and others who need to understand DNA and the law. Anyone working in laboratories and in the courts or anyone studying this issue should own this book.

Book Synopsis Mammals and Birds as Bioindicators of Trace Element Contaminations in Terrestrial Environments by : Elżbieta Kalisińska
Download or read book Mammals and Birds as Bioindicators of Trace Element Contaminations in Terrestrial Environments written by Elżbieta Kalisińska and published by Springer. This book was released on 2019-03-01 with total page 708 pages. Available in PDF, EPUB and Kindle. Book excerpt: The population explosion that began in the 1960s has been accompanied by a decrease in the quality of the natural environment, e.g. pollution of the air, water and soil with essential and toxic trace elements. Numerous poisonings of people and animals with highly toxic anthropogenic Hg and Cd in the 20th century prompted the creation of the abiotic environment, mainly in developed countries. However, the system is insufficient for long-term exposure to low concentrations of various substances that are mainly ingested through food and water. This problem could be addressed by the monitoring of sentinels – organisms that accumulate trace elements and as such reflect the rate and degree of environmental pollution. Usually these are long-lived vertebrates – herbivorous, omnivorous and carnivorous birds and mammals, especially game species. This book describes the responses of the sentinels most commonly used in ecotoxicological studies to 17 trace elements.
Book Synopsis Horns, Pronghorns, and Antlers by : George A. Bubenik
Download or read book Horns, Pronghorns, and Antlers written by George A. Bubenik and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 569 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the first drawings left on walls of ancient caves, human beings have been fascinated with that unique phenomenon of the animal kingdom, the presence of horns and antlers. From the mythical ''unicorn'' exercising the power over life and death to the perceived aphrodisiacal and other medical properties of rhinoceros horns and growing antlers, these conspicuous protuberances have had a significant place in the history of mankind. Part of that ancient interest in antlers and horns was due to their value as sym bols of masculinity; this interest persists today in trophy hunting, an honorable tradition carried on for centuries in many countries of the world. This book, which deals with evolution, morphology, physiology, and behavior, has not been devised as a comprehensive review of the subject of horns, prong horns, and antlers; rather, it is a series of chapters stimulating thoughts, discus sions, and initiation of new studies. As editors, we did not interfere with the content of articles nor with the opin ions and interpretations of our contributors, and we left them to decide whether to accept the suggestions of our reviewers. Despite the fact that various aspects of cranial appendages have been studied since the end of the eighteenth century, many controversial views still exist, as witnessed in various chapters of this book.
Book Synopsis Using Science to Improve the BLM Wild Horse and Burro Program by : National Research Council
Download or read book Using Science to Improve the BLM Wild Horse and Burro Program written by National Research Council and published by National Academies Press. This book was released on 2013-10-04 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using Science to Improve the BLM Wild Horse and Burro Program: A Way Forward reviews the science that underpins the Bureau of Land Management's oversight of free-ranging horses and burros on federal public lands in the western United States, concluding that constructive changes could be implemented. The Wild Horse and Burro Program has not used scientifically rigorous methods to estimate the population sizes of horses and burros, to model the effects of management actions on the animals, or to assess the availability and use of forage on rangelands. Evidence suggests that horse populations are growing by 15 to 20 percent each year, a level that is unsustainable for maintaining healthy horse populations as well as healthy ecosystems. Promising fertility-control methods are available to help limit this population growth, however. In addition, science-based methods exist for improving population estimates, predicting the effects of management practices in order to maintain genetically diverse, healthy populations, and estimating the productivity of rangelands. Greater transparency in how science-based methods are used to inform management decisions may help increase public confidence in the Wild Horse and Burro Program.
