The Amazon forest is one of the world's most complex, unknown and threatened ecosystems that holds a considerable part of the Earth's biodiversity. This ecosystem needs greater scientific attention so that we can better understand the features of its fauna and conserve species before they become extinct. Thus, this book addresses issues about resources within Earth's largest rainforest. In addition, the knowledge of the molluscs in the Amazon region is extremely scarce, and in most cases only information concerning their spatial distribution is available. Specifically, for the gastropods of the Pomacea genus, which were introduced in every continent and became known as pests, scientific knowledge in native areas is very important to understand. Research may help to control these organisms and the many areas they tend to invade. Specialists and scientists that work with apple snails in the Amazon and around the world can access new information about the species that inhabit this region with unprecedented advances in various scientific aspects such as diversity and occurrence, anatomy aspects of Pomacea in Peru, and phylogeny of this group in the Amazon region. Information about the biological aspects such as imposex development, effects of the dry season duration in the gastropod growth, aquaculture technical to human food production, and reproduction (including oviposition, fecundity, substrate selection, ultrastructural view of spermatozoa and egg predation). All of this is synthesized to bring the reader an informative compilation of data and research focusing on apple snails of the Amazon. Target Audience: This book will be relevant to researchers that work with apple snails in Amazon region and others locations around the world, mainly in areas which gastropods are a pests. Besides information about culture techniques and meat quality of Amazon Apple Snails are available, and are very important to culture of these gastropods in large scale to human food. Chapters related to biodiversity, ecology and biology of apple snails also be very useful. Information about parasites that use these gastropods as a host, is also present in this book, and will help to understand the life cycle of these organisms. The information about apple snails in Amazon region is rare, so this book will contribute to improve the knowledge about this freshwater mollusk.

This textbook, which is the first volume in the series Microbial Zoonoses, provides a comprehensive overview of the diagnosis, treatment and control of zoonotic parasitic diseases. The book is divided into two sections; the first section discusses the classification of parasitic zoonoses and includes general information on the diagnosis, treatment, epidemiology, prevention, and control of parasitic zoonoses. It also describes the biological features of these organisms, host-parasite interactions, and the disease spectrum, as well as the importance of public health control measures, such as surveillance, and prophylactic measures in controlling these diseases.The second section explores the important zoonotic diseases caused by ectoparasites, protozoan and helminths parasites. It also reviews the life cycle, pathogenesis, pathology, immunology and clinical manifestations, modern diagnostic methods, treatment regimen, prevention, control, and epidemiology of these parasites.Cutting across the disciplines, this book serves as a guide to postgraduate students, faculty members, public health experts, and medical administrators who are interested in the management of these parasitic zoonotic infections.

Southern Wonder explores Alabama’s amazing biological diversity, the reasons for the large number of species in the state, and the importance of their preservation. Alabama ranks fifth in the nation in number of species of plants and animals found in the state, surpassed only by the much larger western states of California,Texas, Arizona, and New Mexico. When all the species of birds, trees, mammals, reptiles, amphibians, fishes, wildflowers, dragonflies, tiger beetles, and ants are tallied, Alabama harbors more species than 90 percent of the other states in the United States. Alabamais particularly rich in aquatic biodiversity, leading the nation in species of freshwater fishes, turtles, mussels, crayfish, snails, damselflies, and carnivorous plants. The state also hosts an exceptional number of endemic species—those not found beyond its borders—ranking seventh in the nation with 144 species. The state’s 4,533 species, with more being inventoried and discovered each year, are supported by no less than 64 distinct ecological systems—each a unique blend of soil, water, sunlight, heat, and natural disturbance regimes. Habitats include dry forests, moist forests, swamp forests, sunny prairies, grassy barrens, scorching glades, rolling dunes, and bogs filled with pitcher plants and sundews. The state also includes a region of subterranean ecosystems that are more elaborate and species rich than any other place on the continent. Although Alabama is teeming with life, the state’s prominence as a refuge for plants and animals is poorly appreciated. Even among Alabama’s citizens, few outside a small circle of biologists, advocates, and other naturalists understand the special quality of the state’s natural heritage. R. Scot Duncan rectifies this situation in Southern Wonder by providing a well-written, comprehensive overview that the general public, policy makers, and teachers can understand and use. Readers are taken on an exploratory journey of the state’s varied landscapes—from the Tennessee River Valley to the coastal dunes—and are introduced to remarkable species, such as the cave salamander and the beach mouse. By interweaving the disciplines of ecology, evolution, meteorology, and geology into an accessible whole, Duncan explains clearly why Alabama is so biotically rich and champions efforts for its careful preservation.

Ecosystem-based fishery management (EBFM) is rapidly becoming the default approach in global fisheries management. The clarity of what EBFM means is sharpening each year and there is now a real need to evaluate progress and assess the effectiveness and impacts. By examining a suite of over 90 indicators (including socioeconomic, governance, environmental forcing, major pressures, systems ecology, and fisheries criteria) for 9 major US fishery ecosystem jurisdictions, the authors systematically track the progress the country has made towards advancing EBFM and making it an operational reality. The assessment covers a wide range of data in both time (multiple decades) and space (from the tropics to the poles, representing over 10% of the world's ocean surface area). The authors view progress towards the implementation of EBFM as synonymous with improved management of living marine resources in general, and highlight the findings from a national perspective. Although US-centric, the lessons learned are directly applicable for all parts of the global ocean. Much work remains, but significant progress has already been made to better address many of the challenges facing the sustainable management of our living marine resources. This is an essential and accessible reference for all fisheries professionals who are currently practicing, or progressing towards, ecosystem-based fisheries management. It will also be of relevance and use to researchers, teachers, managers, and graduate students in marine ecology, fisheries biology, biological oceanography, global change biology, conservation biology, and marine resource management.

Nowhere on Earth is there an ecological transformation so swift and so extreme as between the snow-line of the high Andes and the tropical rainforest of Amazonia. The different disciplines that research the human past in South America have long tended to treat these two great subzones of the continent as self-contained enough to be taken independently of each other. Objections have repeatedly been raised, however, to warn against imagining too sharp a divide between the people and societies of the Andes and Amazonia, when there are also clear indications of significant connections and transitions between them. Rethinking the Andes–Amazonia Divide brings together archaeologists, linguists, geneticists, anthropologists, ethnohistorians and historians to explore both correlations and contrasts in how the various disciplines see the relationship between the Andes and Amazonia, from deepest prehistory up to the European colonial period. The volume emerges from an innovative programme of conferences and symposia conceived explicitly to foster awareness, discussion and co-operation across the divides between disciplines. Underway since 2008, this programme has already yielded major publications on the Andean past, including History and Language in the Andes (2011) and Archaeology and Language in the Andes (2012).

Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives. This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN. As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms. The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.
