The Biology and Conservation of Elasmobranchs and Chimaeras
As aquatic predators since the Cretaceous period, Elasmobranchs (sharks, skates, rays) and chimaeras, represent one of the oldest vertebrate groups, with very little morphological or physiological adaptations. Though they are remarkably ancient and praised as God-like creatures in some parts of the world, they are among the most feared in the public eye as a consequence of their negative portrayal throughout history. Unfortunately, as it is the case with many aquatic species, in recent years climate change and anthropogenic pressures such as food competition, pollution, and habitat degradation have significantly threatened their populations. On top of this, having low fecundity, late sexual ...

Düşünceler yunus ve balinaların hep şanslı olduğu üzerinedir. Haklarında ufak bilgiye ulaşan herhangi biri, onları görmeyi, dokunmayı hatta birlikte yüzmeyi arzu eder. Oysa bu ilgi gerçekten bir şans olarak tanımlanmalı mıdır? Bir gün onların denizlerini paylaşalım istedik, hiç seslerini çıkarmadılar. Biz paylaşmayı bilmedik onları kendimize düşman bildik. Gerektiğinde katlettik. Onların gülümseyen suratlarını çok istedik, yakaladık tutsak ettik. Dünya üzerinde rahat yaşayalım istedik, onlarla paylaştığımız kaynakları onlara zehir ettik. Şimdi ise ellerinden tutalım istiyoruz, fakat onu bile ne kadar becerebiliyoruz! Bu kitap mesleğimi ve...
Marine Ecosystem Restoration (MER) – Challenges and New Horizons
Worldwide, marine ecosystems have been lost and degraded due to anthropogenic disturbances. For example, oyster reefs have declined by at least ∼85%, coral reefs by ∼19%, seagrasses by ∼29%, North American salt marshes by ∼42%, and mangroves by ∼35% from the early 19th century. Deepwater reefs and deep-sea vents are not immune and have also been reduced in extent in many areas. Factors driving these losses include habitat destruction, pollution, invasive species, overfishing, trawling, mining and, more recently, climate change effects, such as ocean warming, species range changes and acidification. These habitat declines are occurring at a time when marine waters are being used at ...
The Galapagos Marine Reserve
This book focuses on how marine systems respond to natural and anthropogenic perturbations (ENSO, overfishing, pollution, tourism, invasive species, climate-change). Authors explain in their chapters how this information can guide management and conservation actions to help orient and better manage, restore and sustain the ecosystems services and goods that are derived from the ocean, while considering the complex issues that affect the delicate nature of the Islands. This book will contribute to a new understanding of the Galapagos Islands and marine ecosystems.

Monograph of Living Chitons
Chitons form a peculiar and highly interesting class of molluscs, known with certainty to exist since the Ordovician, and widespread in all world seas to depths from 0 to over 7,000 m. In recent years taxonomists all over the world have much contributed to our knowledge of the chitons and their synonymy, so that the number of living species now amounts to some 800. The authors propose to not only compile all actual knowledge about the living chitons, but, where possible, a after a careful study of the type material, to systematically describe and illustrate every known -- or hitherto unknown -- species. In most cases the detailed figures are new and drawn by the senior author, P. Kaas. The "Monograph of Living Chitons" is planned to appear in ten volumes.
Marine Ecology
During the last decades, aquatic resources have been severely depleted due to human-induced factors such as overexploitation and pollution and more recently due to deviations in the physicochemical parameters of oceans, dramatic changes in weather patterns and melting of glaciers. The effects of these man-made factors are occurring in a relatively shorter time scale and, in many cases, are beyond the capacity of organisms to adapt to these deviations. The majority of natural aquatic resources, which are one of the most important food sources on the planet, are being used to the extent that limits their capacity for regeneration. Despite ongoing attempts towards developing strategies for long...
Africa from the Sixteenth to the Eighteenth Century
A history of Africa from the 16th to the 18th centuries, this study concentrates on the continuing evolution of African states and cultures, the increase in external trade, and the consequences of the slave trade. The series is co-published in Africa with seven publishers, in the United States and Canada by the University of California Press, and in association with the UNESCO Press.
Global Atlas of Marine Fisheries
The Global Atlas of Marine Fisheries is the first and only book to provide accurate, country-by-country fishery catch data. This groundbreaking information has been gathered from independent sources by the world's foremost fisheries experts. Edited by Daniel Pauly and Dirk Zeller of the Sea Around Us Project, the Atlas includes one-page reports on 273 countries and their territories, plus fourteen topical global chapters. Each national report describes the current state of the country's fishery; the policies, politics, and social factors affecting it; and potential solutions. The global chapters address cross-cutting issues, from the economics of fisheries to the impacts of mariculture. Extensive maps and graphics offer attractive and accessible visual representations.
Flaws
This book examines the policymaking process following highly emotional events. It focuses on the politics of shark “attacks” by looking at policy responses to tragic shark bites in Florida, Australia, and South Africa. The book reviews these cases by identifying the flaws in the human-shark relationship, including the way sharks are portrayed as the enemy, the way shark bites are seen as intentional, and how policy responses appear to be based on public safety. Flaws identifies politicians as the true sharks of this story for their manipulation of tragic circumstances to protect their own interests. It argues that shark bites are ungovernable accidents of nature, and that we are “in the way, not on the menu.”
