Book excerpt: Crayfish are one of the most iconic freshwater crustacean groups of the world. The wide range of biological adaptations of the freshwater crayfish to the limnetic ecosystems is surprising, as is there is high potential of some taxa to become invasive species. There is a constant growing interest in develop research with freshwater crayfish. They can be an important food source in several countries, the aquarium pet trade and cultural importance, in addition to the presence of several imperiled species. This book brings important reviews of some aspects of diversity, biological features, evolution, habitat characteristics, behavior and conservation strategies of freshwater crayfish, including native taxa, especially endemic from South America, New Guinea and North America, and non-indigenous species. In South American, new species have been discovered in recent years and are classified in threat categories, indicating the need of more studies regarding taxonomy and conservation. For New Guinean species, data about their exploitation by humans and further perspectives about the improvement of conservation practices are presented. In relation to the North American crayfish, this book brings information about some aspects of biology and behavior of the burrowing species Procambarus acanthophorus. A global assessment and future perspectives for all alien crayfish species are also presented in this book. Regarding the partenogenetic marbled crayfish, Procambarus virginalis, the book brings an extensive review covering aspects of detection history, biology, ecology, evolution, systematics and utilization of this species in the world. In additon, an overview of integrative taxonomy studies and cryptic diversity in crayfish is also presented
Download or read book Management of Freshwater Biodiversity written by Julian Reynolds and published by Cambridge University Press. This book was released on 2011-11-10 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: Integrating research into freshwater biodiversity and the role of keystone species, this fascinating book presents freshwater crayfish as representatives of human-exacerbated threats to biodiversity and conservation. It uses examples from these and other large decapod invertebrates to explore how communities function and are controlled, alongside the implications of human demands and conflicts over limited resources, notably the severe impacts on biodiversity. The discussion is structured around three key topics – the present situation of crayfish in world freshwater ecosystems, the applications of science to conservation management and knowledge transfer for successful crayfish management. It outlines the historic exploitation of crayfish, addressing the problems caused by invasive alien forms and explaining the importance of correct identification when dealing with conservation issues. Offering a global perspective on freshwater systems, the book ultimately highlights how the conservation of such large and long-lived species will help protect ecosystem quality in the future.

Available in PDF, EPUB and Kindle. Book excerpt: Crayfish occur on every continent, except for Antarctica and Africa excluding Madagascar, and are a very diverse group of freshwater crustaceans with over 600 species. Crayfish are keystone species, ecosystems engineers, and make up the majority of invertebrate biomass in the systems they inhabit. In Oklahoma, there are 30 known species from six genera, with representatives from the three general ecological morphs that are defined by their burrowing behavior (burrowing types). In the first chapter, I provide a general overview and a synthesis of the questions addressed in my dissertation. The second chapter provides an in-depth account of Oklahoma's crayfish and their biology, including an illustrated dichotomous key for species identification, individual species descriptions with color photographs, and detailed distribution maps. This chapter provided the foundation for research on crayfish biology in my subsequent chapters. Specifically, my studies focused on the 27 epigean species of Oklahoma to address questions regarding the effects of climate change and land use on species distributions (Chapter 3), quantifying morphological variation among taxa to test of the role of evolutionary convergence among burrowing types (Chapter 4), and investigating whether and how trophic resource partitioning can mediate the coexistence of sympatric species (Chapter 5). In Chapter 3, my results suggested that different crayfish burrowing types were affected by distinct bioclimatic variables. Crayfish distributions, however, did not appear to be negatively affected by climate change, and habitat destruction is likely a driving factor in the decline of crayfish. Differences among burrowing types were also highlighted in Chapter 4, which indicated consistent morphological trait variation in species of the same burrowing type, irrespective of taxonomic affiliation, providing evidence for convergent evolution in crayfish morphology. Finally, in Chapter 5, stable isotope analyses indicated that some crayfish species pairs partition their food resources, but there is also evidence for overlap in dietary niches. Overall, my dissertation provides a foundation for the study of crayfish within Oklahoma and surrounding states and provides a basis of better understanding the evolutionary and ecological mechanisms that have lead to and contributed to maintaining crayfish diversity in North America.
Download or read book Freshwater Crayfish Aquaculture in North America Europe and Australia written by Jay Huner and published by CRC Press. This book was released on 1994-04-25 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: Freshwater Crayfish Aquaculture in North America, Europe, and Australia is the first text to summarize the methods of culture for the eight most important crayfish species in the world. Methods developed to culture crayfishes around the world differ significantly, and this book enables readers to develop workable strategies for cultivating different crayfish species in specific environments. Huner and associate authors cover the following topics in detail: methods of crayfish culture crayfish diseases crayfish processing economics of crayfish culture Each of the the three major crayfish industries are well-represented in this new book and special attention is given to the specific needs and accomplishments of each area, which is beneficial to producers in other countries. For example, while hatching technology has been important in Australia and Europe, it hasn?t yet been applied to any degree in North America. At the same time, North America has developed a major crayfish processing industry. Disease problems have resulted in more emphasis on that subject in Europe and yet it is vital to all involved in crayfish aquaculture. Businessmen, farmers, scientists, laymen, or students need to be exposed to the methods and problems associated with crayfish production in different parts of the world if they are to be successful in any crayfish project, whether it be research- or profit-oriented. Freshwater Crayfish Aquaculture in North America, Europe, and Australia is intended to provide all readers with one source of information on the subject of freshwater crayfish aquaculture. Professional staff, advanced students, and extension personnel will find the entire text beneficial. Those in corporate organizations and the agriculture field, especially decisionmakersin operations, will find the methods, markets, and financial considerations in this book a helpful guide.

Book excerpt: Why do we study crayfish? Answers may range from their cultural or economic value to ecological importance to the high conservation need of many species. Freshwater crayfish are an important part of ecosystems in rivers and dams. Crayfishes have become one of the most widely introduced freshwater taxa, and the ecological effects of nonnative crayfishes are well familiar. Crayfish are hosts for multiple ectosymbionts, the most notable of which are clitellate annelid worms of the order Branchiobdellida. Historically, these worms were considered commensal or sometimes parasitic, but recent work has shown that crayfish can benefit from this relationship, at least under certain environmental conditions. Morphology and ecosystem function often reflect land-use practices and state of development or degree of industrialization of a region. Crayfish key roles and attributes in ecosystems include indicators or surrogates for water quality, bioindicators for communities or habitats, keystone controllers of trophic webs and ecological engineers. Protected crayfish may also act as umbrella species for the conservation of communities. Their main habitat templets are cool or warm high quality streams and lakes, warm lower quality wetlands, semiterrestrial swamps and temporary wetlands, and cave ecosystems. This book 'Freshwater Crayfish' deals with the crayfish biology with attention given to crayfish status and conservation, genetic variation and physiological adaptation to the environment, concentrates on ecological roles of freshwater crayfish from a breadth of authors and researchers in different countries and continents working on a wide range of organisms and questions. The knowledge of the reproductive strategy of invasive species is foremost to the understanding of its invasion ecology as it determines the potential for population increase and range expansion. It also attempted to represent insights on field sampling for crayfish from a breadth of researchers in different nations and continents working on a wide range of organisms and questions. This book is an essential reading for anyone involved in the biology or exploitation of these important animals.
