Book excerpt: The purpose of this dissertation was to understand the applied biology of the olive ridley turtle nesting arribada at Playa Ostional, Costa Rica, and Playa La Flor and Playa Chacocente in Nicaragua. Harvest of eggs fromthese beaches was not sustainable. Hatchling production at Ostional and La Flor was insufficient to maintain the current populations of adults and production of hatchlings at Chacocente was marginal. To help ensure the stability of the regional olive ridley population it will be necessary to produce as many hatchlings as possible from the beaches and to reduce at sea mortality of the turtles for the foreseeable future. Hatching success and the production of hatchlings were controlled by the same spatial, temporal, human and environmental factors on all three beaches so those controls appear to be general in nature, at least in the Central American Pacific coast. Density of eggs did not have a significant effect on hatching success or hatchling production. Plots open to harvest, dogs and poaching did not have higher hatching success or higher hatchling production. Thus, removal of eggs by humans and their animals is not an effective means to increase the number of hatchlings produced from these beaches. The best way to increase hatchling production is stop poaching, reduce dog predation, and find ways to increase hatching success. It is not practical to eliminate the harvest at Ostional because the harvest provides important income for the members of ADIO. However, the legal harvest can be restricted to the dry season when eggs typically die from heat and lack of water. In the wet season harvest can be restricted to eggs that are on the surface of the sand due to digging by turtles and eggs that are in danger of being washed away by the estuaries and tides. Ecotourism now produces more income at Ostional than the legal egg harvest. A combination of a well-managed harvest of doomed eggs and ecotourism would provide a conservation plan that would eventually provide new income for local residents and increase hatchling production. A participatory management program is needed on the other beaches as well.

This book was released on 1993 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This document provides information on the biology and exploitation of olive ridley turtles (Lepidochelys olivacea), and it is limited to their distribution in the western Atlantic Ocean. It was originally prepared for the second Western Atlantic Turtle Symposium (WATS II), held in Puerto Rico in 1987, but lack of funds prevented its pUblication at that time. In its present form, the document has been updated (as much as was feasible with the limited access to data resources available in Suriname, the author's current project location) with new information thought to be applicable to the western Atlantic olive ridley turtle populations. In order to provide a systematic treatment of the various data categories, this document follows the FAO species synopsis format as prepared by Rosa (1965) and as applied by Witzell (1983). Topics include taxonomy, morphology, distribution, reproduction, life stages, food, growth, behavior, population characteristics, exploitation, protection, and management"--Preparation of this synopsis

Download or read book The Leatherback Turtle written by James R. Spotila and published by JHU Press. This book was released on 2015-10-30 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Since the first volume of The Biology of Sea Turtles was published in 1997, the field has grown and matured in ways few of the authors would have predicted—particularly in the areas of physiology, behavior, genetics, and health. Volume III presents timely coverage of emerging areas as well as the integration of approaches and information that did not exist even a decade ago. The book assembles the foremost experts in each topic to provide the most up-to-date and comprehensive book on sea turtles available today. New areas covered include in vivo imaging of structure, spatial distributions of marine turtles at sea, epibiosis, imprinting, parasitology, and climatic effects. Life history is explored in three chapters covering age determination, predator-prey interactions, and mortality from bycatch. The Biology of Sea Turtles, Volume III will inspire scientists and students to explore and expand their understanding of these intriguing animals. The book provides clear baseline summaries, thoughtful syntheses, and effective presentation of the most fundamental topics spanning form and function, health, distributions, behavior, genetics, evolution, and ecology. Its scope and depth make it the definitive go-to reference in the field.

This book was released on 2017-08-10 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gathers the most recent research findings on ecology and conservation of marine vertebrates in Latin America, making use of high technological methods to show readers the diversity of the marine research that has been conducted in these countries over the last decades. The book brings authors from more than 23 institutions of 7 different countries developing the most diverse research aiming at ocean conservation through the ecology of different vertebrate animals, such as whales, dolphins, manatees, turtles, seabirds and fish. This book deals with technological advances and innovation in the ecology and conservation of marine vertebrates in Latin America. This eclectic collection is broad in scope but provides detailed summaries of new methods that are deployed in the study of marine environmental conservation. Key issues revolve around the development and application of educational methodologies in the field of marine vertebrate research, which provide a rational basis for better management of marine environments using modern techniques associated with GIS, satellite tracking, aerial systems, bioacoustics, biogeochemistry, genetics, underwater videography, species photoidentification, molecular biology, trophic ecological methods, ethological methods, and behavioural ecology, among others. Discussion and elucidation of these kinds of techniques are aimed at university-level students and post-graduate researchers. The scope of this volume includes whales, sharks, rays, dolphins, tropical fishes, turtles, manatees as well as aspects of Latin American marine ecosystem conservation. Researchers in this biogeographic region, as well as others involved with marine vertebrate research, will find this work essential reading.
