True river dolphins as well as marine dolphins that frequent freshwater systems are large animals that have traditionally gone unnoticed by the general public and, in a certain sense, by marine mammal specialists as well. In fact, only a limited number of researchers have investigated the biology of these dolphin species. This is quite surprising given that these species are commonly the top predators in their habitats. Now for the first time, revolutionary molecular techniques are being applied to answer evolutionary reconstruction questions of many animals, including river dolphins. In addition, new paleontological records are dramatically changing our perspective about the relationships of these dolphins with each other and with other cetaceans. In this book, new census information and important ecological characteristics are provided of the river dolphins Inia, Sotalia, Pontoporia, Lioptes, and Orcaella. For the first time, molecular and genetic results of theses dolphin species are presented. A compilation of these data is essential if we are to present a strategic conservation plan for these animals. Upon being informed of critical evolutionary historical data, conservation biologists will now be able to tailor their conservation efforts for each threatened river dolphin species. Additionally, new morphological data and the new discoveries in the fossil record for river dolphins are examined. The major dolphin specialists in Colombia, Brazil, Bolivia, Argentina, the United States of America, China, and India present their newest results within a single book that graduate students, professors, scientists, evolutionary ecologists, aquatic mammalogists, population ecologists, conservation ecologists, and marine biologists will all find valuable for the foreseeable future.

The Franciscana Dolphin: On the Edge of Survival provides the most updated and comprehensive knowledge on the most endangered marine mammal in the Western South Atlantic Ocean. It synthesizes all available information on this dolphin species, also referred to as La Plata dolphin, ranging from taxonomy, evolution, diet, parasites and diseases, reproduction and growth, to genetic diversity and stock definition, distribution, abundance, behavior, as well as the threats and causes behind the dwindling population numbers. Written by international experts, this book explores aspects of the species’ natural history and urgent problems of accidental mortality in fishing nets, contamination, and habitat loss. It offers the most current research and practices on rehabilitating debilitated animals and presents initiatives at the regional and international level for species conservation, including current and potential strategies related to marine protected areas and public policies. The Franciscana Dolphin: On the Edge of Survival is an important resource for researchers and practitioners in marine conservation, marine biology, and zoology, particularly those who seek to gain the most reputable information on vulnerable marine mammal species for conservation efforts. Policymakers and public officials involved in environmental protection and planning will also find this useful to combat similar threats with other dolphin species around the world Offers the most up-to-date research of the species’ natural history, biology and ecology Discusses current threats and solutions for species conservation, which can be applied to other marine mammal species Provides updates on national and international agreements and policies for conservation efforts

Although all living beings modify their environment, human beings have acquired the ability to do so on a superlative space-time scale. As a result of industrialization and the use of new technologies, the anthropogenic impact has been increasing in the last centuries, causing reductions in the sizes or the extinction of numerous wild populations. In this sense, from the field of conservation genetics, various efforts have been made in recent decades to provide new knowledge that contributes to the conservation of populations, species, and habitats. In this book, we summarize the concrete contributions of researchers to the conservation of the Neotropical mammals using Molecular Ecology techniques. The book is divided into three major sections. The first section provides an up-to-date review of the conservation status of Neotropical mammals, the applications of the molecular markers in its conservation, and the use of non-invasive and forensic genetic techniques. The second and third sections present, respectively, a series of case studies in various species or taxonomic groups of Neotropical mammals.

Mapping phylogenetics on geographical scales is one of the most important scientific aspects of bioscience research. Changes in the environment have evidently shaped the geographical distribution of organisms on land and in the oceans seen today. Overexploitation of key species has caused not only changes in the distribution and diversity of organisms and composition of the ecosystems, but is also leading to species extinction at accelerating rates. It is our duty as scientists to find ways of protecting the species endangered with extinction and preventing other species from entering the endangered stage. To manage this effectively, we need to map species distribution, understand life-history traits, define genetic variation within species and populations, identify lineages - especially at the molecular level - and correlate the historical, phylogenetic components with the spatial distributions of gene lineages. In this book, phylogenetics and phylogeography of a diverse range of organisms are reviewed: from microorganisms causing gastroenteritis in humans, fishes in the Southwest Atlantic Ocean and spiders of the western Indian Ocean, to mountain tapirs in South America and birch tree species of the Arctic tundra.

Ethology And Behavioral Ecology Of Odontocetes written by Bernd Würsig and has been published by Springer this book supported file pdf, txt, epub, kindle and other format this book has been release on 2019-08-02 with Science categories.
This book concentrates on the marine mammalian group of Odontocetes, the toothed whales, dolphins, and porpoises. In 23 chapters, a total of 40 authors describe general patterns of ethological concepts of odontocetes in their natural environments, with a strong bent towards behavioral ecology. Examples are given of particularly well-studied species and species groups for which enough data exist, especially from the past 15 years. The aim is to give a modern flavor of present knowledge of ethology and behavior of generally large-brained behaviorally flexible mammals that have evolved quite separately from social mammals on land. As well, the plight of populations and species due to humans is described in multiple chapters, with the goal that an understanding of behavior can help to solve or alleviate at least some human-made problems.

After being hunted nearly to the point of extinction, the cetaceans have now become a symbol of the need for marine conservation. Today, dolphins and whales are featured in numerous books and television documentaries, which has allowed people to connect with them. Bringing together the most recent research on cetaceans, this volume provides a scientific grounding to our feelings for these distant relatives of ours. Filled with splendid photographs and drawings, the book describes in realistic detail the fascinating biology and behavior of dolphins and whales. Cetaceans returned to the sea about 60 million years ago, and today, represented by 81 species, they have colonized nearly all the world's oceans and some big rivers in South America and Asia. Dolphins and whales have been the subject of many legends, and so this book begins with the history of how humans have viewed these creatures, and then it explains their evolution. The special features that enable these mammals to live like fish, sometimes being able to swim extremely fast (certain dolphin species travel over 31 mph) or dive unusually deep (sperm whales can dive to depths of 9900 feet) are also discussed, along with such topics as echolocation and language. At the end, readers will find an illustrated guide to the various species. A useful tool as well as a visual delight, Dolphins and Whales will be a valued addition to all ocean-lovers' libraries.
