Book Description
This book presents the main drivers of benthic structure and processes in estuaries from the 8,000 km-Brazilian coast, assesses the influence of natural and human disturbance, and discusses their ecological importance and management needs. Estuaries are unique coastal ecosystems often with low biodiversity that sustain and provide essential ecological services to mankind. These ecosystems include a variety of habitats with their own sediment and fauna dynamics, all of them globally altered or threatened by human activities. Mangroves, saltmarshes, tidal flats and other confined estuarine systems are under increasing stress by overfishing and other human activities leading to habitat and species loss. Combined changes in estuarine hydromorphology and in climate pose severe threats to estuarine ecosystems at a global scale.

Book Description
This book provides an overview of the tropical marine environments of Brazil and a multi-disciplinary assessment of the impact of ongoing climate change in these environments. These changes will affect physical, biological and biogeochemical characteristics of coastal zones and oceans, modifying their ecological structure, their functions and the various services provided to humans and have the potential of causing severe socioeconomic impacts in local (coastal zone), regional (continental shelf and shallow seas) and global (ocean) scales. The Tropical Brazil presents a unique opportunity to evaluate how spatial and temporal heterogeneity influences the response and resilience of marine environments to climate changes. This region comprises the main reef constructions of the Western South Atlantic Ocean, the majority of the Brazilian deltas, one of the longest mangrove areas of the world, a very narrow and shallow continental shelf, extreme variations in sediment and nutrient flows, as well as undeniable importance in transferring heat and mass between hemispheres.

Book Description
This book integrates a variety of issues such as regional settings of productivity and nutrient cycling; plankton of coastal and shelf systems; plankton, climate change and human-induced changes; harmful algae and their impacts; and gelatinous zooplankton. This book explores the intriguing marine plankton communities of the SWA region of South America encompassing low to high latitude environments, framed by a complex hydrographic background and global climate change. This vast and iconic region has been largely under-recognized and under-studied. However, in recent years a strong interest has emerged along with the acknowledgment of its high biological productivity. The book concludes by discussing conservation in the region, highlighting regional biodiversity hotspots where the challenges of climate change, habitat loss, and other threats to biodiversity may be particularly acute. Plankton Ecology of the Southwestern Atlantic is a timely synthesis of the field, setting a new baseline for future research. It will be important reading for both researchers and graduate students, and will also be of interest and use to a professional audience of oceanographers, conservation biologists, stake holders and educated science enthusiasts

Book Description
The ‘Aquatic Habitat Conservation in South America’ Symposium occurred during the XXI Brazilian Society of Ichthyology Meeting. The proceedings were published as a special issue in the Journal of Fish Biology (vol. 89, Number 1, June 2016). In this special issue, authors provided an analytical overview of problems faced by the conservation of fishes and aquatic habitats of South America. Habitat loss emerged as the greatest concern for all South American aquatic ecosystems, with a long list of causes related to unsustainable development models. Based on this finding, we would like to extend this topic to other continents, different climates, fauna and flora around the world. Our goal is to provide a comprehensive and multidisciplinary overview of variables that influence flora and fauna distributions and shape their ecological interactions within aquatic ecosystems

Book Description
The indiscriminate use of chemical substances in industrial processes and anthropogenic activities, have resulted in the release of these compounds into aquatic ecosystems through municipal, hospital and industrial discharges, producing various undesired effects on the environment and on species of ecological interest. These compounds, such as metals, pesticides, emerging pollutants and other substances are persistent and susceptible to biotic and/or abiotic transformations, yielding metabolites that can be more toxic than the original compounds. In this book, researchers from diverse environmental science disciplines share their experiences in countries such as Argentina, Brazil, Colombia and Mexico, and critically examine the problem of contaminants in aquatic ecosystems in Latin America, as well as the risks presented by their presence.

Book Description
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 image is modified based on Figure 1a of Lucey et al. (this Research Topic) and Figure 7b of Niemi et al. (this Research Topic). (A) Graphical depiction of atmospheric warming and increasing atmospheric carbon dioxide (CO2atm), which drives ocean warming, contribute to the decreases in dissolved oxygen (DO), and lowers pH and saturation state index of calcium carbonate (Ω). The partial pressure of CO2 (pCO2) increases due to increasing atmospheric CO2 that is absorbed into the seawater (i.e., ocean acidification), along with other biological processes in the marine environment.
