Understanding Galapagos

by Sehoya Cotner, release date 2013-01-25, Understanding Galapagos Books available in PDF, EPUB, Mobi Format. Download Understanding Galapagos books, We wanted a book that includes up-to-date information about evolution in Galápagos, yet is accessible by professional biologists, laypeople, students, armchair travelers, and the merely curious. Naming the endemic-and often curious-organisms in Galápagos from checklists can be rewarding; that's why you will find checklists of the islands' iconic species in this book (Chapter 12). But understanding what you see is a different adventure, and that is one thing that we hope distinguishes this book from others. In short, we wanted to write a book that would help you not lust identify what you see, but understand what you see. Such an understanding goes beyond identification guides and traditional natural history and requires a context that includes the islands' biology, geology, climate, and history. In this book, you will find discussions (and checklists) of the native and endemic organisms you'll see, especially the iconic ones such as penguins, land and marine iguanas, finches, giant tortoises, and albatrosses (see color images). However, we have not described all of the organisms on the islands-after all, there are more than 600 species of lichens and 2,9OO species of marine organisms, not to mention the more than 50 families, 300 genera, and 370 species of endemic and native beetles. Similarly, we discuss many, but not all, of the most troublesome introduced species (at last count, there were more than 1,400 such species). We have focused on the native and endemic "stars" of Galápagos that fill tourists' must-see lists. Although our book emphasizes evolution, we have also addressed several other topics, for evolution cannot be understood without a corresponding understanding of its context: namely, the geology, climate, and historical impact of humans on the ecosystem. This is why you will find discussions of the islands' geology, weather, trails, and Visitor Sites in this book. We also wrote this book to emphasize the importance of preserving Galápagos, as well as to help readers understand the challenges facing the islands. To ensure accuracy and consistency, the information in this book was derived from visiting the islands more than 30 times over many years; talking with numerous Galápagos National Park Service guides, boat captains, boat crews, school teachers and other residents of Galápagos, and former prisoners at the Wall of Tears penal colony; documenting the GPS coordinates of more than 350 sites, usually with two independent GNPS units (Appendix 1); studying documents at a variety of libraries, research stations, and related locations such as GNPS, Charles Darwin Research Station, National Geospatial Intelligence Agency, and Instituto Oceanografico de la Armada; being on the bridge with boat captains in the most challenging conditions and regions of the islands (Appendix 2); and, when necessary, hiking, scuba diving, and interviewing local residents to resolve controversies (e.g., the exact location of Jessica; see Chapter 11).

Understanding Invasive Species In The Galapagos Islands

by María de Lourdes Torres, release date 2018-02-15, Understanding Invasive Species In The Galapagos Islands Books available in PDF, EPUB, Mobi Format. Download Understanding Invasive Species In The Galapagos Islands books, This book investigates the introduction of invasive species and their behavior in oceanic islands. How can we define invasive species? What is their history? How did they come to dominate and transform ecosystems? These are relevant questions when trying to understand the behavior of invasive species—primarily in fragile ecosystems such as islands—and to understand the biological, ecological, social and economic impacts of invasions. We chose the Galapagos Islands, a place well-known to be unique in the study of evolution, as a laboratory to analyze the interactions between invasive and endemic species, to understand the makeup of the ecosystems emerging after invasions have occurred, to describe the relationships of invasives with the people that live in these islands, and to try to develop comprehensive analyses on this topic from multi-scalar and multi-disciplinary points of view. For a long time, the discussion has been about how proper management of the species could achieve two main goals: the eradication of the species to recover affected ecosystems and the conservation of endemic species. The discussion has taken on other nuances, including the suggestion that an invasive species, when it is already adapted to an ecosystem, forms an integral part of it, and thus eradication would in itself go against conservation. On the other hand, some invasive species are not only part of the biological compound of the island ecosystems, but they also form part of the social and cultural history of the inhabited islands. Some of these identified by the local inhabitants are species of real or potential economic value.

Download Gal Pagos An Encyclopedia Of Geography History And Culture books, This encyclopedia provides readers with a comprehensive look at the Galápagos Islands, from the wildlife and scientists that made them famous to the challenges and issues the islands face today. In the mid-1800s, the Galápagos Islands served as Charles Darwin's playground, a volcanic archipelago where he famously worked on his theories of evolution and natural selection. But who actually discovered the islands? Why didn't any country claim them for over 200 years? And is ecotourism hurting or helping these mysterious islands? This volume explores the history, science, and culture of the Galápagos Islands. A Preface, Introduction, Chronology, and Galápagos at a Glance primer introduce readers to the islands that are so famously associated with Charles Darwin. Twelve thematic essays allow readers to explore topics such as evolution, the geology of the islands, invasive species, and tourism in depth. Topical entries follow, covering key individuals and organizations as well as other important concepts and ideas. Thirteen primary document excerpts allow readers to study firsthand accounts from explorers and visitors to the islands. Appendices, a glossary, a bibliography, and sidebars round out the text. Students of history, geography, and science will find this volume informative, while general readers will be intrigued to learn about these unique islands. Thematic essays introduce readers to the Galápagos Islands, providing deep coverage on the geography and geology of the islands, as well as such topics as Charles Darwin, evolution, tourism, and other topics Alphabetically arranged topical entries allow readers to search for a wide range of topics, complete with cross-references and Further Readings Primary document excerpts from scientists and explorers provide readers with firsthand accounts of travelers' observations and experiences on the islands Appendices provide context about the islands and Charles Darwin's expedition in 1835 that helped to make the islands famous A Glossary helps to define key terms and concepts for readers A Chronology outlines key events through history that helped to shape the Galápagos Islands as we know them today

Galapagos Giant Tortoises

by , release date 2020-11-07, Galapagos Giant Tortoises Books available in PDF, EPUB, Mobi Format. Download Galapagos Giant Tortoises books, Galapagos Giant Tortoises brings together researchers and conservationists to share the most up-to-date knowledge of Galapagos giant tortoises. Despite being icons of the world-famous Galapagos Archipelago and the target of more than 50 years of conservation research and management, Galapagos giant tortoise evolution and much of their ecology remained unknown until recently. This book documents the history, the pressing conservation issues, and success stories recovering several of the 15 different species of Galapagos tortoises from near extinction. The book begins with an overview of the history of the relationship between humans and Galapagos giant tortoises, starting from initial heavy exploitation of tortoises by pirates and whalers, and extending to the start of the modern conservation era in the 1960s. The book then shifts to biology, describing Galapagos tortoise evolution, taxonomy, ecology, habitats, reproduction, and behavior. Next the decades of conservation efforts and their results are reviewed, including issues of captive breeding, invasive species, introduced diseases, and de-extinction, as well as the current status and distribution of every species. The final portion of the book turns to four case studies of restoration, and then looks ahead to the future of all tortoise populations.The latest volume in the Biodiversity of the World: Conservation from Genes to Landscape series, Galapagos Giant Tortoises is a valuable resource for researchers and conservationists, as well as students of biology, wildlife conservation, and herpetology. Provides a comprehensive overview of the Galapagos giant tortoise species as written and edited by the world’s leading experts Presents examples of restoration of tortoise populations following the near extinction of many of them Describes conservation strategies to ensure the full recovery of all extant species Explores recent efforts using replacement tortoises for extinct species to restore island ecosystems

Food Webs And The Dynamics Of Marine Reefs

by Tim McClanahan, release date 2008-04-16, Food Webs And The Dynamics Of Marine Reefs Books available in PDF, EPUB, Mobi Format. Download Food Webs And The Dynamics Of Marine Reefs books, Biologists have made significant advances in our understanding of the Earth's shallow subtidal marine ecosystems, but the findings on these disparate regions have never before been documented and gathered in a single volume. Now, in Food Webs and the Dynamics of Marine Reefs, Tim R. McClanahan and George M. Branch fill this lacuna with a comparative and comprehensive collection of nine essays written by experts on specific aquatic regions. Each essay focuses on the food webs of a respective ecosystem and the factors affecting these communities, from the intense and direct pressure of human influence on fisheries to the multi-vector contributors to climate change. The book covers nine shallow water marine ecosystems from selected areas throughout the world: four coral reef systems, three hard bottom systems, and two kelp systems. In summarizing their organization, human influence on them, and recent developments in these ecosystems, the authors contribute to our understanding of their ecological organization and management. Food Webs and the Dynamics of Marine Reefs will be a useful tool for all benthic marine investigators, providing an expert, comparative view of these aquatic regions.

Biogeochemical Applications Of Compound Specific Radiocarbon Analysis

by Ann Pearson, release date 1999, Biogeochemical Applications Of Compound Specific Radiocarbon Analysis Books available in PDF, EPUB, Mobi Format. Download Biogeochemical Applications Of Compound Specific Radiocarbon Analysis books, Compound-specific carbon isotopic (delta 13C and delta 14C) data are reported for lipid biomarkers isolated from Santa Monica Basin (SMB) and Santa Barbara Basin (SBB) surface sediments. These organic compounds represent phytoplanktonic, zooplanktonic, bacterial, archaeal, terrestrial, and fossil carbon sources. The lipids include long-chain n-alkanes, fatty acids (as FAMEs), n-alcohols, C(30) mid-chain ketols and diols, sterols, hopanols, and ether-linked C(40)-biphytanes of Archaca. The data show that the carbon source for most of the biomarkers is marine euphotic zone primary production or subsequent heterotrophic consumption of this biomass. Two lipid classes represent exceptions to this finding. Delta 14C values for the n-alkanes are consistent with mixed fossil and contemporary terrestrial plant sources. The archaeal isoprenoid data reflect chemoautotrophic growth below the euphotic zone. The biomarker class most clearly representing marine phytoplanktonic production is the sterols. It is suggested, therefore, that the sterols could serve as paleoceanographic tracers for surface-water DIC. The isotopic data are used to construct two algebraic models. The first calculates the contributions of fossil and modern vascular plant carbon to SMB n-alkanes. This model indicates that the delta 14C of the modern component is +235% (post-bomb) or 0% (pre-bomb). The second model uses these values to determine the origin of sedimentary TOC. The results are comparable to estimates based on other approaches and suggest that approx. 60% of SMB TOC is of marine origin, modern terrestrial and fossil sources contribute approx. 10% each, and the remaining approx. 20% is of unknown origin.

The Galapagos

by Karen S. Harpp, release date 2014-10-06, The Galapagos Books available in PDF, EPUB, Mobi Format. Download The Galapagos books, The Galápagos Islands are renown for their unique flora and fauna, inspiring Charles Darwin in the elaboration of his theory of evolution. Yet in his Voyage of the Beagle, published in 1839, Darwin also remarked on the fascinating geology and volcanic origin of these enchanted Islands. Since then, the Galápagos continue to provide scientists with inspiration and invaluable information about ocean island formation and evolution, mantle plumes, and the deep Earth. Motivated by an interdisciplinary Chapman Conference held in the Islands, this AGU volume provides cross-disciplinary collection of recent research into the origin and nature of ocean islands, from their deepest roots in Earth's mantle, to volcanism, surface processes, and the interface between geology and biodiversity. Volume highlights include: Case studies in biogeographical, hydrological, and chronological perspective Understanding the connection between geological processes and biodiversity Synthesis of decades of interdisciplinary research in physical processes from surface to deep interior of the earth In-depth discussion of the concept of the island acting as a natural laboratory for earth scientists Integrated understanding of the Galápagos region from a geological perspective Collectively, The Galápagos presents case studies illustrating the Galápagos Archipelago as a dynamic natural laboratory for the earth sciences. This book would be of special interest to a multidisciplinary audience in earth sciences, including petrologists, volcanologists, geochronologists, geochemists, and geobiologists.
