Book Description
Lionfish have been observed at multiple locations along the east coast of the United States, with the majority found between Miami, Florida and North Carolina. The occurrence of lionfish represents one of the first documented invasions of a marine fish species in the western Atlantic. Most lionfish observed along the southeast US shelf have been at depths greater than 35 m, whereas in their native range lionfish inhabit depths from shore to 50 m. One potential limiting factor in the distribution of lionfish on the southeast US continental shelf is winter water temperature. In particular, the northern and inshore distribution of lionfish is predicted to be temperature limited, with Cape Hatteras as the northernmost limit for overwintering. To examine this hypothesis, temperature tolerance studies were conducted following the critical thermal minimum protocol with death as the modified endpoint. Along with temperature at death (CTMin), observations on activity and feeding behavior were recorded. Overall mean CTMin was 9.95 & deg;C (SD = 0.86) and mean temperature at feeding cessation was 16.07 & deg;C (SD = 2.14). Rate of temperature decrease and acclimation temperature did not have a significant effect on CTMin or feeding cessation. No fish were observed eating below 13 & deg;C. When combined with February water temperatures, lionfish thermal tolerance data predicted that lionfish could overwinter on the southeast US continental shelf, with a northern limit of Cape Hatteras and successful inhabitance limited to offshore of the 13 & deg;C isotherm. Although lionfish can tolerate temperatures lower than 13 & deg;C, lower temperatures may limit overwintering by controlling feeding behavior. The continental shelf break (200 m isobath) marks the offshore limit for lionfish on the southeast US continental shelf. The current southern limit of the invasion is not bound by temperature, as lionfish could survive but have not yet been reported on the Florida coast south of Miami. Possibl.

Book Description
The conservation, sustainable use and development of aquatic genetic resources (AqGR) is critical to the future supply of fish. The State of the World’s Aquatic Genetic Resources for Food and Agriculture is the first ever global assessment of these resources, with the scope of this first Report being limited to cultured AqGR and their wild relatives, within national jurisdiction. The Report draws on 92 reports from FAO member countries and five specially commissioned thematic background studies. The reporting countries are responsible for 96 percent of global aquaculture production. The Report sets the context with a review of the state of world’s aquaculture and fisheries and includes overviews of the uses and exchanges of AqGR, the drivers and trends impacting AqGR and the extent of ex situ and in situ conservation efforts. The Report also investigates the roles of stakeholders in AqGR and the levels of activity in research, education, training and extension, and reviews national policies and the levels of regional and international cooperation on AqGR. Finally, needs and challenges are assessed in the context of the findings from the data collected from the countries. The Report represents a snapshot of the present status of AqGR and forms a valuable technical reference document, particularly where it presents standardized key terminology and concepts.

Book Description
The State of the World's Biodiversity for Food and Agriculture presents the first global assessment of biodiversity for food and agriculture worldwide. Biodiversity for food and agriculture is the diversity of plants, animals and micro-organisms at genetic, species and ecosystem levels, present in and around crop, livestock, forest and aquatic production systems. It is essential to the structure, functions and processes of these systems, to livelihoods and food security, and to the supply of a wide range of ecosystem services. It has been managed or influenced by farmers, livestock keepers, forest dwellers, fish farmers and fisherfolk for hundreds of generations. Prepared through a participatory, country-driven process, the report draws on information from 91 country reports to provide a description of the roles and importance of biodiversity for food and agriculture, the drivers of change affecting it and its current status and trends. It describes the state of efforts to promote the sustainable use and conservation of biodiversity for food and agriculture, including through the development of supporting policies, legal frameworks, institutions and capacities. It concludes with a discussion of needs and challenges in the future management of biodiversity for food and agriculture. The report complements other global assessments prepared under the auspices of the Commission on Genetic Resources for Food and Agriculture, which have focused on the state of genetic resources within particular sectors of food and agriculture.

Book Description
Venomous Indo-Pacific lionfish (Pterois miles and P volitans) are now established along the Southeast U.S.A. and parts of the Caribbean and pose a serious threat to reef fish communities of these regions. Lionfish are likely to invade the Gulf of Mexico and potentially South America in the near future. Introductions of lionfish were noted since the 1980s along south Florida and by 2000 lionfish were established off the coast of North Carolina. Lionfish are now one of the more numerous predatory reef fishes at some locations off the Southeast U.S.A. and Caribbean. Lionfish are largely piscivores that feed occasionally on economically important reef fishes. The trophic impacts of lionfish could alter the structure of native reef fish communities and potentially hamper stock rebuilding efforts of the Snapper-Grouper Complex. Additional effects of the lionfish invasion are far-reaching and could increase coral reef ecosystem stress, threaten human health, and ultimately impact the marine aquarium industry. Control strategies for lionfish are needed to mitigate impacts, especially in protected areas. This book provides a general overview of the biology and ecology of lionfish including genetics, taxonomy, reproductive biology, early life history and dispersal, venom defence and predation, and feeding ecology. In addition, alternative management actions for mitigating the negative impacts of lionfish, approaches for reducing the risk of future invasions, and directions for future research are provided.

Book Description
'An interesting book catering perhaps for a more specific audience. It does however provide a somewhat new view of the problems of the field of biological invasions and is worth the effort.' - Ann Sundqvist, M2 Best Books 'Once again, Charles Perrings and colleagues have broken new ground by applying economic and ecological analysis to the very real problem of biological invasions. This is path-breaking work in what promises to be a new sub-discipline within environmental economics.' - David Pearce, University College London, UK Biological invasions - the introduction of living organisms beyond their original range - are one of the main drivers of biodiversity loss. They are a major threat to human health and a source of pests and pathogens in the world's farms, forests and fisheries. The growth of international trade and travel means that more species are being introduced to more places than ever before. This book represents the first concerted effort to understand the economic causes and consequences of biological invasions. The volume discusses the theoretical and methodological issues raised by invasion, including control strategies, modelling options, and a study of the economic, institutional and policy conditions that predispose countries to biological invasions. Also included are case studies of fisheries, agricultural systems, tropical forests and protected areas affected by invasive species in locations such as the Black Sea, Australia and Africa, and an evaluation of control programmes.

Book Description
Invasive alien plants and animals are known for their disruption of ecosystems and threat to biodiversity. This book highlights their major impact on human health. This includes not only direct effects through contact with the species via bites, wounds and disease, but also indirect effects caused by changes induced in ecosystems by invasive species, such as more water hyacinth increasing mosquito levels and thereby the potential for malaria. Covering a wide range of case studies from different taxa (animals and plants), and giving an overview of the diverse impacts of invasive species on health in developed and developing countries, the book is a significant contribution that will help in prioritizing approaches to controlling invasive species and mitigating their health effects. It covers invasive plants, marine species, spiders and other arachnids, ticks and dust mites, insects, mosquitos and other diptera, freshwater species (invertebrates and fishes), amphibians and reptiles, birds and mammals. The broad spectrum of the analyzed case studies will ensure the appeal of the book to a wide public, including researchers of biological invasions, doctors, policy-makers and managers, and students of invasive species in ecology, animal and plant biology and public health medicine.

Book Description
Biological invasions are considered to be one of the greatest threats to the integrity of most ecosystems on earth. This volume explores the current state of marine bioinvasions, which have been growing at an exponential rate over recent decades. Focusing on the ecological aspects of biological invasions, it elucidates the different stages of an invasion process, starting with uptake and transport, through inoculation, establishment and finally integration into new ecosystems. Basic ecological concepts - all in the context of bioinvasions - are covered, such as propagule pressure, species interactions, phenotypic plasticity, and the importance of biodiversity. The authors approach bioinvasions as hazards to the integrity of natural communities, but also as a tool for better understanding fundamental ecological processes. Important aspects of managing marine bioinvasions are also discussed, as are many informative case studies from around the world.
