Conservation of Pacific Sea Turtles
Across the Pacific, populations of some species of sea turtles face extinction unless recent dramatic declines are reversed. The continuing decline of leatherbacks and loggerheads in particular illustrates the limitations of the current gradual and unilateral approach to conservation. Recovery requires instead a holistic solution that addresses all sources of mortality throughout the entire life history and habitat use of these transnational populations. Historically conservation efforts have focused on nesting sites to protect eggs and breeding females; mortality from coastal and highseas fisheries was not addressed. In the past five years, these recovery efforts have widened to include rig...
The Dusky Dolphin
The Dusky Dolphin: Master Acrobat Off Different Shores covers various topics about the dusky dolphin, including its taxonomy, history and demography, ecology, and behavior. After introducing the dusky dolphin as a member of the genus Lagenorhynchus under the family Delphinidae, the book continues by describing its life history, its demographic patterns, and its role in the food web considering predation, parasitism, and competition. The book also includes chapters that discuss the interaction of the dusky dolphin with its habitats, such as the dusky dolphin's sound production, its foraging at night and in daylight, its survival strategies in response to predator threats, the mating habits of...
Incidental catch of vulnerable species in Mediterranean and Black Sea fisheries – A review
Bycatch – a term widely used to refer to part of the catch unintentionally caught during a fishing operation, in addition to target species, and consisting of the discards and incidental catch of vulnerable species – is considered one of the most important threats to the profitability and sustainability of fisheries, as well as to the conservation of the marine environment and ecosystems. Understanding the bycatch issue and adopting effective measures in order to reduce bycatch rates are essential steps towards minimizing the impacts on vulnerable species and ensuring both a sustainable fisheries sector and healthy seas. In the Mediterranean and the Black Sea, the incidental catch of vul...

Secret Worlds
Beyond our hearing, rats and mice sing to woo females. Beyond our sight, bees see the ultraviolet markings of flowers. Beyond our conception, sea turtles sense latitude and longitude through an internal magnetic map, and sharks experience the electric fields created by prey. So many animals sense their environment in rich, strange, and often exquisitely refined ways, including ways beyond the limits of our own senses that scientists have only relatively recently identified. In this book, Martin Stevens describes these astonishing worlds of experience hidden from us: what drove their evolution, how scientists learn about them, and the puzzles that remain. Book jacket.
