This important and exciting title represents the first authoritative volume focussed on pelagic (open ocean) sharks as a group. Virtually every pelagic shark expert in the world has contributed to this landmark publication which includes the latest data and knowledge on pelagic shark biology, fisheries, management, and conservation. Pelagic sharks face unprecedented levels of exploitation in all the world's oceans through both direct fisheries and by-catch, and effective management for these species is contingent upon solid science and data, which this book brings together for the first time. All those involved in shark biology will need to have a copy of this book.
National and international agencies need assessments of change in ecosystems and their drivers in order to sustain natural systems, to maintain the delivery of services, and to meet the challenge for conserving Earth ecosystems in the long term. In marine systems, change may arise directly from human activities (e.g. fisheries), indirectly from local or global activities (cascading effects through food webs from fisheries or changing environments from climate change and/or ocean acidification), or from naturally varying processes. A particular challenge for managers is to identify how dangerous future climate change will be for ecosystems and their services and whether mitigation or adaptati...
Winner of the 2017 Paul Sweezy Marxist Sociology Book Award from the American Sociological Association Although humans have long depended on oceans and aquatic ecosystems for sustenance and trade, only recently has human influence on these resources dramatically increased, transforming and undermining oceanic environments throughout the world. Marine ecosystems are in a crisis that is global in scope, rapid in pace, and colossal in scale. In The Tragedy of the Commodity, sociologists Stefano B. Longo, Rebecca Clausen, and Brett Clark explore the role human influence plays in this crisis, highlighting the social and economic forces that are at the heart of this looming ecological problem. In ...

In International Law of Sharks, Erika J. Techera and Natalie Klein provide an in-depth analysis of the current legal frameworks that relate to these important species. The authors offer ways in which to overcome obstacles that prevent existing laws from working better and identify best practice global governance options while highlighting opportunities for legal reform. Scientific evidence indicates that sharks play a critical role in maintaining marine ecosystem health, yet current governance regimes have not been effective and many shark species continue to diminish. In this context, effective laws are critical to improve sharks’ conservation status. This volume also explores the broader relevance of oceans governance by identifying appropriate legal frameworks and regulatory mechanisms that balance conservation and utilisation of marine species in general.
This assessment is the first overview of the conservation status of 877 northern African freshwater species belonging to five taxonomic groupsfish, molluscs, dragonflies and damselflies, freshwater crabs and aquatic plantsin accordance with the IUCN regional Red List guidelines. Species at risk of regional extinction are mapped and conservation measures are proposed to reduce the probability of future declines.
This report contains a review of the conservation status of 165 Mediterranean species of dragonflies occurring in the Mediterranean basin, according to the IUCN regional Red Listing criteria. It identifies species that are threatened with extinction at regional level so that appropriate conservation action can be taken improve their status.
One of the main reasons cited for inadequate representation of biodiversity in the development processes is a lack of readily available information on inland water taxa. In response to this need for basic for information on species, the IUCN Species Programme conducted a regional assessment of the status and distribution of 2,261 taxa of freshwater fishes, molluscs, odonates, crabs and selected families of aquatic plants from throughout central Africa. This study is based on the collation and analysis of existing information, and the knowledge of regional experts.
