This book was released on 2007 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dispersal and speciation in the marine environment have long been key topics in evolutionary biology and more recently in conservation biology. The genus Sebastes, with approximately 110 species, is found throughout most of the world's cold-temperate seas. Their breadth of phenotypic and species diversity, ecological dominance, and importance to world fisheries has made them a focus of intensive study by countless researchers. In this dissertation, DNA sequence and microsatellite data were used to investigate patterns of speciation, distribution, and mating habits. In Chapter I, DNA sequence data from seven mitochondrial and two nuclear genes, were used to evaluate possible geographic origin, patterns and timing of dispersal, speciation patterns and drivers, and inter-species relationships. The data support a middle Miocene origin for Sebastes spp. in deep habitats of the Northwest Pacific followed by dispersal into the Northeast Pacific and eventually into the southern hemisphere, driven by progressive cooling and strengthening of major ocean currents. Previous hypothesized relationships, shown to be mostly poly- or para- phyletic, were revised in light of the findings. Chapter I provided evidence for two new "cryptic" species. In Chapter II, sequence of the mitochondrial cytochrome b gene, in combination with nine microsatellite loci, was used to evaluate the geographic and bathymetric range of the vermilion rockfish species complex, as well as test for reproductive isolation between the putative species. Genetic analyses supported the presence of two species, separated primarily by depth of adult occurrence. This finding, in association with distribution patterns of 12 recent species pairs, suggests a novel speciation mode based upon the loss/truncation of an ontogenetic migration phase. In Chapter III, DNA sequence data from Chapter II was used to evaluate patterns of population connectivity and gene flow within the vermilion rockfish. A range-wide analysis showed high levels of genetic heterogeneity, likely driven by limited larval dispersal and barriers to gene flow across major oceanographic features. Patterns of paternity and mating system were investigated in Chapter IV using microsatellite loci. Paternity analyses were performed on larvae from both captive and wild populations, representing most major lineages found in Chapter I. Ten of the 17 examined species, showed evidence for multiple sires within a single brood. The implications for genetic diversity produced by this polygynandrous mating system are discussed.

Download or read book Biodiversity Conservation and Phylogenetic Systematics written by Roseli Pellens and published by Springer. This book was released on 2016-02-24 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about phylogenetic diversity as an approach to reduce biodiversity losses in this period of mass extinction. Chapters in the first section deal with questions such as the way we value phylogenetic diversity among other criteria for biodiversity conservation; the choice of measures; the loss of phylogenetic diversity with extinction; the importance of organisms that are deeply branched in the tree of life, and the role of relict species. The second section is composed by contributions exploring methodological aspects, such as how to deal with abundance, sampling effort, or conflicting trees in analysis of phylogenetic diversity. The last section is devoted to applications, showing how phylogenetic diversity can be integrated in systematic conservation planning, in EDGE and HEDGE evaluations. This wide coverage makes the book a reference for academics, policy makers and stakeholders dealing with biodiversity conservation.

Available in PDF, EPUB and Kindle. Book excerpt: Marine fishes have been intensively studied, and some of the fundamental ideas in the science of marine ecology have emerged from the body of knowledge derived from this diverse group of organisms. This unique, authoritative, and accessible reference, compiled by 35 luminary ecologists, evolutionary biologists, and ichthyologists, provides a synthesis and interpretation of the large, often daunting, body of information on the ecology of marine fishes. The focus is on the fauna of the eastern Pacific, especially the fishes of the California coast, a group among the most diverse and best studied of all marine ecosystems. A generously illustrated and comprehensive source of information, this volume will also be an important launching pad for future research and will shed new light on the study of marine fish ecology worldwide. The contributors touch on many fields in biology, including physiology, development, genetics, behavior, ecology, and evolution. The book includes sections on the history of research, both published and unpublished data, sections on collecting techniques, and references to important earlier studies.

Download or read book Global Biogeography written by J.C. Briggs and published by Elsevier. This book was released on 1995-10-13 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book significantly expands the coverage of this subject given by its predecessor Biogeography and Plate Tectonics (1987). Global Biogeography traces global changes in geography and biology from the Precambrian to the Recent (with worldwide coverage in chronological order); examines the evolutionary effects of the major extinctions, and discusses contemporary biogeographic regions within the context of their historic origins. It is now apparent that the biotas of the various biogeographical regions have had, and still maintain, a dynamic relationship with one another; much more than was previously thought. This is shown to be true for all three of the earth's primary habitats; marine, terrestrial and freshwater (as is clearly demonstrated in this volume). The book is splendidly illustrated with 122 text figures, an extensive bibliography, index, together with a set of biogeographic maps illustrating continental and terrain outlines from the mid-Cambrian to the Recent. University students (both advanced undergraduate and graduate level) will find it an excellent text book. For professionals in Biogeography this is a convenient reference work.
