The dramatic biography of a slaveship turned freedom-fighter--which brings new insights into Britain's involvement in the end of the trade in enslaved people In 1827 the Royal Navy purchased a Baltimore clipper and renamed her the Black Joke. Assigned to the Preventative Squadron, she patrolled the west coast of Africa and freed 3,692 captives from enslavement. Beloved by seafarers and celebrated by the public, the Black Joke would become the most famous weapon in the campaign for abolition. But in her previous life as the Henriqueta, the Black Joke had been a slave ship. Through the experiences of slavers and abolitionists, captives and crew, Stephen Taylor charts the vessel's extraordinary double life. As the Henriqueta she operated as an engine of atrocity, trafficking over 3,000 captives to plantations in Brazil. But subsequently manned by British seamen and Liberian Kru, the Black Joke became the scourge of Spanish and Brazilian slavers. She did so despite limited resources, neglect, and even obstruction by the authorities at home. Taylor offers a gripping account of the world of the transatlantic trade, through the eyes of its perpetrators--and those who sought its end.

The sustainable exploitation of the marine environment depends upon our capacity to develop systems of management with predictable outcomes. Unfortunately, marine ecosystems are highly dynamic and this property could conflict with the objective of sustainable exploitation. This book investigates the theory that the population and behavioural dynamics of predators at the upper end of marine food chains can be used to assist with management. Since these species integrate the dynamics of marine ecosystems across a wide range of spatial and temporal scales, they offer new sources of information that can be formally used in setting management objectives. This book examines the current advances in the understanding of the ecology of marine predators and will investigate how information from these species could be used in management.

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.

Sharks: Predators of the Sea reveals the true nature of these remarkable prehistoric creatures. As an apex predator in their watery world, they are critical to the health of the world's oceans but also largely misunderstood.
