East Africa is one of the most diverse and interesting tropical area on the planet. It is home not only to the last great megafaunal assemblage, but also to human populations with the highest growth rates. This book draws on the expertise of leading ecologists, each intimately familiar with a particular set of East African ecosystems, to provide the first in-depth and integrated account of the ecology, management, threats, and conservation of these diverse ecosystems. Summarizing the tremendous wealth of scientific research that has come out of East Africa in the last few decades, each chapter analyzes a given ecosystem type, taking the reader through the basics of its ecology, its historical use (and misuse) by humans, and its prospects for conservation. Throughout the book, linkages and similarities among ecosystems are emphasized, the historical and contemporary role of humans in shaping these ecosystems is considered, fundamental principles of ecology are considered, and interesting case studies are highlighted. Students and researchers in ecology, conservation biology, and environmental sciences will find this book useful in their work.

The World of Catfishes

Although African catfishes are not as diverse taxonomically as those of the Amazon, they include unique groups such as the Mochokidae, in which there are more than 100 species, and the Malapteruridae, which can generate electricity.

This important publication provides, for the first time, a comprehensive review of knowledge of reproductive seasonality in teleosts. It addresses why a particular species should show such seasonality, and how environmental cues act as regulators to ensure that reproductive maturation and breeding occur at the optimum time. The book considers the ultimate factors responsible for the evolution of reproductive seasonality in fish. It reviews salient concepts of reproductive seasonality in mammals. This volume also includes a review of accumulated knowledge of the control mechanisms of salmonids, gasterosteids, temperate cyprinids, cyprinodonts and other brackish-water forms, and marine and tropical freshwater teleosts. This is a work of value to research scientists in the field of environmental physiology, reproductive biology, and comparative neuroendocrinology and endocrinology. In addition, it is relevant for institutions involved with aquaculture and fisheries management. It is useful for post-graduate as well as undergraduate courses in fish biology and various related subjects.

Spark from the Deep tells the story of how human beings came to understand and use electricity by studying the evolved mechanisms of strongly electric fish. These animals have the ability to shock potential prey or would-be predators with high-powered electrical discharges. William J. Turkel asks completely fresh questions about the evolutionary, environmental, and historical aspects of people’s interest in electric fish. Stimulated by painful encounters with electric catfish, torpedos, and electric eels, people learned to harness the power of electric shock for medical therapies and eventually developed technologies to store, transmit, and control electricity. Now we look to these fish as an inspiration for engineering new sensors, computer interfaces, autonomous undersea robots, and energy-efficient batteries.

Risk management is increasingly gaining attention within the aquaculture sector, as reflected in the development and increasing implementation of better management practices, codes of conduct and codes of good practice, standard operational procedures, certification and traceability. Aquaculture insurance is one of the tools used in the management of risks in aquaculture. This publication provides an overview of the current status of aquaculture stock insurance in the world. Seven syntheses covering Asia, China, Europe, North America, Oceania, South America and sub-Saharan Africa show the specificities of the situation with regard to aquaculture stock insurance. The publication also presents a summary of these syntheses, together with conclusions and clear recommendations at various levels to increase the contribution of aquaculture stock insurance to the sustainable management and development of the aquaculture sector.
