Book Description
Studies on transgenic fish, in contrast to mammals, are still in their infancy. However, it is evident that such fish will not only be of considerable economic benefit to aquaculture but will enable scientists to make quantum leaps in their understanding of the physiological and biochemical mechanisms unique to fish, and of the developmental biology of vertebrates in general.The potential of transgenic fish for research and industrial development is beginning to be widely recognized. This timely volume encompasses the full spectrum of current research on transgenic fish. It will be valuable to many scientists who intend to explore the merits of the technology for the first time.

Book Description
Originally published in 1990 Tropical Resources presents in-depth coverage of the extremely diverse tropical environments, the resources to be found within the region and their production, and ecological management. The book discusses economic geography and ways of utilizing available resources, including those of tropical forests, wildlife, tidal wetlands and the sea. The book also include chapters on the development and land use of protected areas, the ecological aspects of pasture resources; and the impacts of economic development and population damage. In addition, studies are offered on tropical soils, including their distribution properties and management and the ecological processes at work in tropical forests. For geographers, economists and policymakers, the book provides a wealth of information on tropical resources and their potential development.

Book Description
Published in 1995: This book is not designed as a culture manual for herbivorous fishes, but the reader is directed to other sources. This book should meet the needs that exist for a comprehensive publication on herbivorous fishes.

Book Description
Ecosystem management has emerged in the past several years as the new paradigm for managing public and private land. It combines the principles of ecosystem-level ecology with the policy requirements of resource and public land management. This collection of selected readings will serve as an introduction to the concepts of biological diversity, ecological process, biotic integrity, and ecological sustainability that underlie ecosystem management.

Book Description
INVASIVE ALIEN SPECIES Invasive Alien Species: Observations and Issues from Around the World Volume 1: Issues and Invasions in Africa Invasive alien species are spreading into new ecosystems each year. The impacts caused by these invaders can be swift and devastating. The topic of invasive alien species is large, complex, and globally significant at various scales, exacerbated by the globalization of world economies and increased trade and commerce that has overcome natural barriers to species movement. Invasive alien species threaten global food supplies, water quality and availability, and energy production and delivery. With the added risks associated with global climate change, the global homogenization of plants, animals, and microbes is a major factor in the decline in ecosystem health and ecosystem services worldwide. To counter this trend, there is a critical need to unify governments, cultures, and programs to improve cross-boundary coordination to effectively address the wide range of invasive alien species threats to the environment, economies, and to plant and animal health; particularly human health. This 4-volume work is the first to compile a set of useful material for key topics, to provide a better understanding of the overall global threat of invasive alien species and the diverse array of problems faced around the world, and assemble material that includes potential replicable solutions to overcome these threats. The books also highlight the threat posed by invasive alien species in terms of a global ‘call to action’. Since invasive species know no boundaries, it is our hope that by compiling material from different scientific and social perspectives around the world, and sharing knowledge and examples of a diverse array of associated topics, we can advance global awareness and improve unified national responses to the threat posed by invasive alien species.
