Book Hybridization in the Northern Flicker  Colaptes Auratus  Reveals the Genomic Architecture of Feather Coloration

Download or read book Hybridization in the Northern Flicker Colaptes Auratus Reveals the Genomic Architecture of Feather Coloration written by Stepfanie Maria Aguillon and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Birds possess a remarkable diversity of feather coloration-from dark blacks and grays to bright reds and yellows. The genetic bases of these color differences have been sought for a long time, but we are just beginning to be able to understand the relationship between genotype and phenotype in non-model systems. Here, I perform an in-depth analysis of phenotypic and genotypic variation in the northern flicker complex (Colaptes auratus), a common North American woodpecker, to further our understanding of feather coloration in birds. For this work, I leverage the extensive hybridization between the yellow-shafted and red-shafted subspecies of the northern flicker in the Great Plains. This hybrid zone has been studied intensely for many years due to their distinct coloration differences, most notably the difference in the wing and tail color (the eponymous "shaft") which varies from brilliant yellow to salmon red. I first assess phenotypic variation across an identical transect of the hybrid zone in historic and contemporary sampling periods, and document a westward movement of the hybrid zone towards the range of the red-shafted flicker. I then explore population genetic patterns using a reduced-representation genomic sequencing approach and am able to separately cluster the taxa for the first time, but identify an extremely low-level of baseline divergence nonetheless. Finally, I use whole-genome sequencing and subsequent targeted sequencing to identify regions of the genome associated with the coloration differences in the flickers and assess how interactions between these genomic regions influence coloration. Collectively, these studies have furthered our understanding of the long-studied flicker hybrid zone and the genetic basis of coloration in birds.

Book A Naturalist  s Guide to the Great Plains

Download or read book A Naturalist s Guide to the Great Plains written by Paul A. Johnsgard and published by Lulu.com. This book was released on 2018 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book documents nearly 500 US and Canadian locations where wildlife refuges, nature preserves, and similar properties protect natural sites that lie within the North American Great Plains, from Canada's Prairie Provinces to the Texas-Mexico border. Information on site location, size, biological diversity, and the presence of especially rare or interesting flora and fauna are mentioned, as well as driving directions, mailing addresses, and phone numbers or internet addresses, as available. US federal sites include 11 national grasslands, 13 national parks, 16 national monuments, and more than 70 national wildlife refuges. State properties include nearly 100 state parks and wildlife management areas. Also included are about 60 national and provincial parks, national wildlife areas, and migratory bird sanctuaries in Canada's Prairie Provinces. Many public-access properties owned by counties, towns, and private organizations are also described.

Book Hybrid Zones and the Evolutionary Process

Download or read book Hybrid Zones and the Evolutionary Process written by Richard Gerald Harrison and published by Oxford University Press, USA. This book was released on 1993 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hybrid zones--geographical areas in which the hybrids of two races are found--have attracted the attention of evolutionary biologists for many years, both because they are windows on the evolutionary process and because the patterns of animals and plant variation seen in hybrid zones do notfit the traditional classification schemes of taxonomists. Hybrid zones provide insights into the nature of the species, the way barriers to gene exchange function, the genetic basis of those barriers, the dynamics of the speciation process. Hybrid Zones and the Evolutionary Process synthesizes theextensive research literature in this field and points to new directions in research. It will be read with interest by evolutionary biologists, geneticists, and biogeographers.

Book Ecology of North America

  • Author : Brian R. Chapman
  • Publisher : John Wiley & Sons
  • Release : 2015-04-09
  • ISBN : 1118971574
  • Pages : 352 pages

Download or read book Ecology of North America written by Brian R. Chapman and published by John Wiley & Sons. This book was released on 2015-04-09 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: North America contains an incredibly diverse array of naturalenvironments, each supporting unique systems of plant and animallife. These systems, the largest of which are biomes, formintricate webs of life that have taken millennia to evolve. Thisrichly illustrated book introduces readers to this extraordinaryarray of natural communities and their subtle biological andgeological interactions. Completely revised and updated throughout, the second edition ofthis successful text takes a qualitative, intuitive approach to thesubject, beginning with an overview of essential ecological termsand concepts, such as competitive exclusion, taxa, niches, andsuccession. It then goes on to describe the major biomes andcommunities that characterize the rich biota of the continent,starting with the Tundra and continuing with Boreal Forest,Deciduous Forest, Grasslands, Deserts, Montane Forests, andTemperature Rain Forest, among others. Coastal environments,including the Laguna Madre, seagrasses, Chesapeake Bay, and barrierislands appear in a new chapter. Additionally, the book covers manyunique features such as pitcher plant bogs, muskeg, the polar icecap, the cloud forests of Mexico, and the LaBrea tar pits.“Infoboxes” have been added; these include biographiesof historical figures who provided significant contributions to thedevelopment of ecology, unique circumstances such as frogs andinsects that survive freezing, and conservation issues such asthose concerning puffins and island foxes. Throughout the text,ecological concepts are worked into the text; these includebiogeography, competitive exclusion, succession, soil formation,and the mechanics of natural selection. Ecology of North America 2e is an ideal first text forstudents interested in natural resources, environmental science,and biology, and it is a useful and attractive addition to thelibrary of anyone interested in understanding and protecting thenatural environment.

Book The Quaternary of the U S

  • ISBN : 1400876524
  • Pages : 933 pages

Download or read book The Quaternary of the U S written by Herbert Edgar Wright and published by Princeton University Press. This book was released on 2015-12-08 with total page 933 pages. Available in PDF, EPUB and Kindle. Book excerpt: This important volume reviews the status of investigations aimed at deciphering the geologic, biogeographic, and archaeological records for the Quaternary Era—the last million years of geologic time-for the area of continental United States. Over eighty Quaternary scientists have contributed to the fifty-five chapters divided into four main parts. Part 1 treats the areal geology, with emphasis on the stratigraphy of the glaciated areas east of the Rocky Mountains, unglaciated eastern and central United States, and western United States. Part 2 deals with biogeography: phytogeography and palynology, animal geography and evolution. Part 3 deals with archaeology prehistory in the northeastern states, southeastern states, plains, desert west, and Pacific Coast including Alaska. Part 4 covers many diverse Quaternary studies on—the continental shelves, isotope geochemistry, paleopedology, the geochemistry of some lake sediments, paleohydrology, glaciers and climate, volcanic-ash chronology, paleomagnetism, neo-tectonics, dendrochronology, and theoretical paleoclimatology. Originally published in 1965. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
