DOWNLOAD EBOOK →The Amazon forest is one of the world's most complex, unknown and threatened ecosystems that holds a considerable part of the Earths 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 Earths 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 synthesised to bring the reader an informative compilation of data and research focusing on apple snails of the Amazon.

DOWNLOAD EBOOK →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.

DOWNLOAD EBOOK →This book introduces updated information on conservation issues, providing an overview of what is needed to advance the global conservation of freshwater decapods such as freshwater crabs, crayfish, and shrimps. Biodiversity loss in general is highest in organisms that depend on intact freshwater habitats, because freshwater ecosystems worldwide are suffering intense threats from multiple sources. Our understanding of the number and location of threatened species of decapods, and of the nature of their extinction threats has improved greatly in recent years, and has enabled the development of species conservation strategies. This volume focuses on saving threatened species from extinction, and emphasizes the importance of the successful implementation of conservation action plans through cooperation between scientists, conservationists, educators, funding agencies, policy makers, and conservation agencies.
