Book Morphometric and Genetic Variation Among Populations of the Southern Short tailed Shrew Blarina Carolinensis Located Along the Coastal Plain of Virginia

Download or read book Morphometric and Genetic Variation Among Populations of the Southern Short tailed Shrew Blarina Carolinensis Located Along the Coastal Plain of Virginia written by Devon Kersten and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The distribution of short-tailed shrews, Blarina carolinensis and B. brevicauda, demonstrates contiguous allopatry in peninsular situations in the Coastal Plain of Virginia, and in other areas. The distribution of these two species is unusual in that they do not exhibit syntopy except within a narrow corridor along the borders of their ranges. Interestingly, along the Coastal Plain of Virginia, B. carolinensis is generally found only at the distal ends of the peninsular areas, existing as local populations that appear to be isolated from each other and from the primary population that exists in south-central Virginia. It is thought that the disjunct distribution of B. carolinensis populations results from the unique physiography of Chesapeake Bay, namely peninsular water barriers, and that the intervening distribution of its congener, B. brevicuada, should promote morphometric and population differentiation due to isolation. Whether populations of B. carolinensis along the Coastal Plain of Virginia are truly isolated (and possibly morphologically and/or genetically dissimilar to the continuous southeastern Unites States distribution) is unknown. I examined cranial morphometrics and molecular genetic characters (mitochondrial DNA control region and exon-primed intron-crossing nuclear DNA, EPIC) from peninsular populations of B. carolinensis and compared them to shrews of the mainland population to address this question. The sources of specimens were shrews ensnared in discarded bottles along roadsides, museum skins, and specimens frozen in alcohol. Principle coordinate analyses did not indicate a correlation between cranial morphology and genetic structuring of the populations. MANOVA analyses correlate distinct geographic regions with variation of four cranial measurements related to length. A 492 base pair region of the mitochondrial control region was obtained for many specimens and found to be polymorphic resulting in 27 unique haplotypes evenly partitioned across populations reflecting low levels of differentiation. Nuclear DNA markers were not found to exhibit repeatable amplification and therefore were not useful. Genetic variance detected among populations ranged from [phi]PT = 0.001 to 0.045. The effective number of migrants (Nem), as estimated from the standard relationship with [phi]PT values, indicated panmixia. Both sets of observations indicated that physiography and B. brevicauda are not as severe factors limiting migration among the Coastal Plain populations of B. carolinensis as was thought.

Book An Assessment of Haplotype and Nucleotide Diversity in the Southern Short tailed Shrew Blarina Carolinensis

Download or read book An Assessment of Haplotype and Nucleotide Diversity in the Southern Short tailed Shrew Blarina Carolinensis written by Anthony Christopher Grow and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The control region of mitochondrial DNA in the southern short-tailed shrew (Blarina carolinensis) was examined to further understand haplotype and nucleotide diversity of the species within a chromosomal-polymorphic zone in western Tennessee, as well as, in populations west of the Mississippi River. A congruent 214 base-pair region of 78 aligned sequences was analyzed from populations in western Tennessee, eastern Arkansas, eastern Texas, and eastern Oklahoma. Of the 78 sequences, 54 unique haplotypes were found. High haplotype and nucleotide diversity were reported for each locality and for the area sampled as a whole. Fixation indices also further support the degree of haplotype diversity within and among populations of B. carolinensis. Populations showed moderate genetic divergence; yet, genetic variation within populations was greater than among populations. The study provides new insight into genetic variation within B. carolinensis.

Book Atlas of Mammalian Chromosomes

Download or read book Atlas of Mammalian Chromosomes written by Stephen J. O'Brien and published by John Wiley & Sons. This book was released on 2006-04-14 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: A stunning visual collection of the banded metaphase chromosomekaryotypes from some 850 species of mammals, the Atlas of MammalianChromosomes represents an unabridged compendium of the state ofthis genomic art form. Bringing together information currentlyscattered throughout the cytogenetics literature for scores ofpublished and unpublished species, this atlas features high-qualitykaryotype images for nearly every mammal studied to date, making itthe most comprehensive assemblage of high-resolution chromosomephotographs available--a critically invaluable resource for today'scomparative genomics era. For every available species, the Atlas of Mammalian Chromosomespresents the best karyotype produced, the common and Latin name ofthe species, the published citation, and the contributing authors.Most karyotypes are G-banded, revealing the chromosomal bar codesof homologous segments among related species. Addressing the mandate of the Human Genome Project to annotate thegenomes of other organisms as well, the Atlas of MammalianChromosomes offers a step forward in our understanding of speciesformation, of genome organization, and of DNA script for naturalselection. It is an invaluable resource for geneticists,mammalogists, and biologists interested in comparative genomics,systematics, and chromosome structure.

Book Mammals of the Southeastern United States

Download or read book Mammals of the Southeastern United States written by Troy L. Best and published by University Alabama Press. This book was released on 2020-08-25 with total page 493 pages. Available in PDF, EPUB and Kindle. Book excerpt: First comprehensive account of the mammals of the entire southeastern US The southeastern United States is home to a remarkable and diverse mammalian fauna that is a significant part of the region’s rich natural heritage. Mammals of the Southeastern United States presents accounts of 137 species that currently or previously occurred in the Southeast. Although accessible and useful for the generalist, this book provides an up-to-date compilation of basic knowledge about native and nonnative mammals of the region that is suitable for students of all ages and for professional mammalogists and biologists alike. This volume profiles common species like the eastern gray squirrel, the white-tailed deer, and the Virginia opossum, but also includes among its accounts many extant species, such as the jaguar and porcupine, that once occurred in the region; native species, like the Caribbean monk seal, that are now extinct; native species that have been extirpated, or wiped out, from all or part of the region, such as the red wolf, cougar, American bison, and elk; and many introduced species, including the Mexican mouse opossum, common squirrel monkey, and capybara. Each species account includes full-color images of the animal, plates featuring at least three views of its skull, color distribution maps of its approximate geographic range in the Southeast and in North America, and an up-to-date synthesis of several aspects of its biology, including habitat, diet, predators, parasites, diseases, and behaviors. An introductory chapter on conservation summarizes the current status of mammalian populations in the region and provides insight into some of the threats mammals now encounter in the Southeast.
