In ecosystems, sharks can be predators, competitors, facilitators, nutrient transporters, and
food. However, overfishing and other threats have greatly reduced shark populations …

Any attempt to describe the spatial ecology of sharks and rays should consider the drivers
responsible for movement. Research has shown fluctuations in the environment (abiotic …

In recent years, scientists have realized that evolution can occur on timescales much shorter
than the" long lapse of ages" emphasized by Darwin—in fact, evolutionary change is …

Fisheries and aquaculture production, imports, exports and equitability of distribution
determine the supply of aquatic food to people. Aquatic food security is achieved when a …

Global chondrichthyan (shark, ray, skate and chimaera) landings, reported to the United

Over the past 4 decades there has been a growing concern for the conservation status of
elasmobranchs (sharks and rays). In 2002, the first elasmobranch species were added to …

Impacts of chronic overfishing are evident in population depletions worldwide, yet indirect
ecosystem effects induced by predator removal from oceanic food webs remain …

This topical and exciting textbook describes fisheries exploitation, biology, conservation and
management, and reflects many recent and important changes in fisheries science. These …

Human impacts on the world's oceans have been substantial, leading to concerns about the
