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.

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

This book offers a new ecosystemic approach to the understanding of mangrove and salt marsh ecosystems. Brazil has one of the largest areas of mangroves in the world, where salt marshes might or might not be associated. Different landscapes comprise the extensive coastline, where mangrove and salt marsh species’ composition is discussed through the analysis of physiography, zonation, and succession processes. Both salt marsh and mangrove plants and the associated macroalgae will be characterized in their ecophysiological and phenological aspects, as well as genetic and epigenetic diversity. The chapters on microbial diversity and litterfall expose the well-known importance of these ecosystems as highly productive carbon sinks and pumps. The associated fauna of invertebrates (benthic meio and macrofaunas, especially brachyuran crabs) and vertebrates (fishes, birds, and mammals) are presented in a special section. The conservational approach encompasses issues, such as historical ecology, economic valuation, protected areas, environmental education, climate changes, and adaptive management.

The Topic Editors Stephanie Brodie, Christopher Cvitanovic, Maria Grazia Pennino, Jon Lopez and André Frainer declare that they are members of the IMBeR (Integrated Marine Biosphere Research) network and IMECaN (Interdisciplinary Marine Early Career Network) and are collaborating with the IMBeR research community.

As aquatic predators since the Cretaceous period, Elasmobranchs (sharks, skates, rays) and chimaeras, represent one of the oldest vertebrate groups, with very little morphological or physiological adaptations. Though they are remarkably ancient and praised as God-like creatures in some parts of the world, they are among the most feared in the public eye as a consequence of their negative portrayal throughout history. Unfortunately, as it is the case with many aquatic species, in recent years climate change and anthropogenic pressures such as food competition, pollution, and habitat degradation have significantly threatened their populations. On top of this, having low fecundity, late sexual maturation and slow growth rates as well as their opportunistic feeding behavior make them vulnerable to commercial fisheries even though, in most cases, they are not the target species. As a result, nowadays many species are endangered, some data-deficient or nearly extinct with the need for urgent knowledge for conservation actions. Producing science-based information on elasmobranchs and chimaeras is crucial for population sustainability, conservation and management actions. In this Research Topic, we invite author contributions on elasmobranchs and chimaeras biology and ecology (e.g., reproduction biology, feeding ecology, age and growth), distribution, migration and many other aspects to bring together this imperative knowledge to provide a base for conservation and management actions, locally or regionally.
