Available in PDF, EPUB and Kindle. Book excerpt: "Through analysis of mitochondrial DNA (mtDNA) sequences, I examined phylogeographic relationships among moose (Alces alces) from Europe, Asia, and North America and inferred historic population trends explaining present-day structure of genetic variance. Diversity of mucleotide composition in cytochrome 'b' was low worldwide, with no variation detected among North American moose. The North American lineage was more closely related to European than to Asian lineages, indicating a recent colonization of North America and refuting the theory of eastern and western races of moose. An analysis of the control region provided greater resolution, which revealed similar yet more detailed patterns, including detectable variation within North America subspecies. Patterns of genetic variation among regional populations identified central Asia as the source of extant lineages of moose. Moreover, a recent coalescence was indicated, with the most recent common ancestor dating to the last ice age. Two historic expansions of moose populations were detected: an initial exansion in Eurasia coincident with an interstade of the last ice age, and a second expansion in eastern Asia and North America following the end of the last ice age. Data indicate a low effective population size in Eurasia during the peak of the last ice age followed by population and range exansion, likely facilitated by climate change. Haplotypes within North America formed a star phylogeny, indicative of recent expansion. Nucleotide and haplotype diversity were greatest in central North America and least in peripheral populations (Alaska, Colorado, and eastern North America). My data indicate a pattern of colonization consistent with a large central population providing founders for peripheral populations, perhaps resulting from leptokurtic dispersal. Low diversity in Alaska indicated a bottleneck susequent to colonization and recent population expansion. Establishment of regional populations through small numbers of founders combined with selection pressure for smaller body size likely led to morphological differentiation among regional populations and likely was adequate for rapid development of subspecies. Nucleotide and haplotype diversity were low in southeastern Alaska, but were high in neighboring areas of British Columbia; there little sharing of haplotypes occurred despite close proximity, indicating recent admixture of separate colonizing populations"l--Leaves iii-iv.

This book was released on 2013 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spatial heterogeneity is an important feature of populations and species. Here, I examine well - characterized populations of moose (Alces alces) in southeastern Alaska for population structure on the inter-population and intra-population scale using genetic techniques. Within inter-population scale, I find that the moose populations of southeastern Alaska have considerable structure, exceeding that found in the remainder of exceeding Alaska, and comparable to introduced populations that went through major bottlenecks. I find that founder effects are likely a major source for creating genetic differentiation between populations. This differentiation is then maintained through limited dispersal, likely due to the complex topography of the region. I also provide new evidence that the subspecific boundary between A. a. andersoni and A. a. gigas is further north than previously appreciated. On the intra-population scale, I use two well-studied moose populations, and using characterized calving areas, find strong genetic structure among both populations within a small (

Available in PDF, EPUB and Kindle. Book excerpt: "The authors have done a superb job of distilling a vast amount of information on the biology of the terrestrial mammals of the eastern United States in a style that will not only satisfy the expert's need for accurate data but will also appeal to students and others interested in natural history." —James N. Layne, Archbold Biological Station In their definitive work on eastern mammals, John O. Whitaker, Jr., and W. J. Hamilton, Jr., vividly convey their sheer delight at the variety and abundance of mammalian life. They have brought together a wealth of biological information and applied a biological subspecies concept to the mammals of the eastern United States. Their research extends "from the high reaches of Mount Katahdin in northern Maine, where water shrews and moose hold company," to the unglaciated hills of southern Indiana, where pygmy shrews (each weighing less than a dime) lived undetected until 1981. From there, they reach to "the cypress swamps of lower Florida, where the spoor of the mountain lion may be seen."*Describes the animals, their behavior, and dispersion in all 27 states east of the Mississippi River.*Almost entirely rewritten, this edition provides an abundance of scientific information in combination with anecdotes, field notes, and an underlying reverence for the fragile diversity of animal life. *Illustrations include 110 range maps, 167 black-and-white photographs, and 92 color images.*Covers 121 species, 17 more than in the previous edition. *Uses a biological subspecies concept, showing the results of evolution through differentiation. *Provides keys to orders and genera, anatomical line drawings. *Summarizes information on endangered and threatened species for each of the eastern states. *Lists state mammal books in the literature section.

This book was released on 2012-03-07 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mapping phylogenetics on geographical scales is one of the most important scientific aspects of bioscience research. Changes in the environment have evidently shaped the geographical distribution of organisms on land and in the oceans seen today. Overexploitation of key species has caused not only changes in the distribution and diversity of organisms and composition of the ecosystems, but is also leading to species extinction at accelerating rates. It is our duty as scientists to find ways of protecting the species endangered with extinction and preventing other species from entering the endangered stage. To manage this effectively, we need to map species distribution, understand life-history traits, define genetic variation within species and populations, identify lineages - especially at the molecular level - and correlate the historical, phylogenetic components with the spatial distributions of gene lineages. In this book, phylogenetics and phylogeography of a diverse range of organisms are reviewed: from microorganisms causing gastroenteritis in humans, fishes in the Southwest Atlantic Ocean and spiders of the western Indian Ocean, to mountain tapirs in South America and birch tree species of the Arctic tundra.
Download or read book Deer and People written by Naomi Sykes and published by Windgather Press. This book was released on 2014-09-30 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deer have been central to human cultures throughout time and space: whether as staples to hunter-gatherers, icons of Empire, or the focus of sport. Their social and economic importance has seen some species transported across continents, transforming landscape as they went with the establishment of menageries and park. The fortunes of other species have been less auspicious, some becoming extirpated, or being in threat of extinction, due to pressures of over-hunting and/or human-instigated environmental change. In spite of their diverse, deep-rooted and long standing relations with human societies, no multi-disciplinary volume of research on cervids has until now been produced. This volume draws together research on deer from wide-ranging disciplines and in so doing substantially advances our broader understanding of human-deer relationships in the past and the present. Themes include species dispersal, exploitation patterns, symbolic significance, material culture and art, effects on the landscape and management. The temporal span of research ranges from the Pleistocene to the modern day and covers Europe, North America and Asia. Papers derived from international conferences held at the University of Lincoln and in Paris.
