Sea Turtles of the Eastern Pacific available in PDF, EPUB and Kindle. Sea turtles are flagship species for the world's oceans. They traverse international boundaries during their migrations, serve as vehicles for marine nutrients to terrestrial habitats, and embody the often tenuous relationship between human action and ecosystem health. The East Pacific Ocean is home to some of the most dynamic marine ecosystems, and the most unique sea turtles. Marine biodiversity within this massive ocean region abounds in mangrove estuaries, seagrass pastures, coral reefs, the open ocean, and many other habitats, with sea turtles often the most conspicuous species present. The distinctive traits of the Eastern Pacific have resulted in the smallest leatherbacks, a singular morph of the green turtle, dark and steeply domed olive ridleys, and the most cryptic hawksbills on the planet. Only now are we beginning to understand how these varieties have evolved. However, the oceanographic conditions that make this an epicenter of sea turtle activity also promote massive artisanal and industrial fishing efforts that, coupled with illegal harvesting of eggs and turtles, have led to declines of several turtle populations in the region. The essays and stories in Sea Turtles of the Eastern Pacific describe for the first time the history of this exploitation, as well as recent sea turtle conservation initiatives and scientific research in the region. The first third of the book considers the biology of the turtles, focusing on general overviews of current ecological management challenges facing the turtles' survival. The second third treats issues of marine policy related to turtle conservation. In conclusion, the book offers six compelling stories of conservation success. By the end, readers will have gained a in-depth view not only of these magnificent creatures, but also the people involved in research and conservation efforts in one of the most remarkable regions of our planet.

Download and read online ebook The Leatherback Turtle write by James R. Spotila. This book was released on 2015-10-30. The Leatherback Turtle available in PDF, EPUB and Kindle. The most comprehensive book ever written on leatherback sea turtles. Weighing as much as 2,000 pounds and reaching lengths of over seven feet, leatherback turtles are the world’s largest reptile. These unusual sea turtles have a thick, pliable shell that helps them to withstand great depths—they can swim more than one thousand meters below the surface in search of food. And what food source sustains these goliaths? Their diet consists almost exclusively of jellyfish, a meal they crisscross the oceans to find. Leatherbacks have been declining in recent decades, and some predict they will be gone by the end of this century. Why? Because of two primary factors: human redevelopment of nesting beaches and commercial fishing. There are only twenty-nine index beaches in the world where these turtles nest, and there is immense pressure to develop most of them into homes or resorts. At the same time, longline and gill net fisheries continue to overwhelm waters frequented by leatherbacks. In The Leatherback Turtle, James R. Spotila and Pilar Santidrián Tomillo bring together the world’s leading experts to produce a volume that reveals the biology of the leatherback while putting a spotlight on the conservation problems and solutions related to the species. The book leaves us with options: embark on the conservation strategy laid out within its pages and save one of nature’s most splendid creations, or watch yet another magnificent species disappear.

Download and read online ebook Assessment of Sea-Turtle Status and Trends write by National Research Council. This book was released on 2010-10-07. Assessment of Sea-Turtle Status and Trends available in PDF, EPUB and Kindle. All six species of sea turtles found in U.S. waters are listed as endangered or threatened, but the exact population sizes of these species are unknown due to a lack of key information regarding birth and survival rates. The U.S. Endangered Species Act prohibits the hunting of sea turtles and reduces incidental losses from activities such as shrimp trawling and development on beaches used for nesting. However, current monitoring does not provide enough information on sea turtle populations to evaluate the effectiveness of these protective measures. Sea Turtle Status and Trends reviews current methods for assessing sea turtle populations and finds that although counts of sea turtles are essential, more detailed information on sea turtle biology, such as survival rates and breeding patterns, is needed to predict and understand changes in populations in order to develop successful management and conservation plans.
