Category : Nature
Languages : en
Pages : 320
Book Description
Based on the Inaugural Albatross Conference in Hobart in 1995. Thirteen chapters are based directly on conference papers, and ten have been written subsequently. Topics covered include albatross taxonomy, ecology, feeding and breeding habits, population and distribution as well as the effect of human activities on albatross mortality. Examines the conservation of albatrosses and threats to their survival, in particular the incidental mortality associated with long line fisheries. Appraises recent research in albatross biology, ecology and conservation and discusses opportunities for future research.
Tuna

Pages : 490
Book Description
Annotation Tuna are biologically fascinating, with many specializations such as endothermy (warm-bloodedness), aerobic capacity, and migratory abilities. The primary focus of this book is the physiology of tuna with respect to biomechanics, thermoregulation, and morphology. An evolutionary and phylogenetic backdrop illustrates the importance of comparative perspectives. Because of the economic importance of tuna, a secondary focus of the book is tuna aquaculture and conservation.

Book Description
Birds are among the most extensively studied of all animal groups. Hundreds of academic journals and thousands of scientists are devoted to bird research, while amateur enthusiasts (called birdwatchers or, more commonly, birders) probably number in the millions. Birds are categorised as a biological class, Aves. The earliest known species of this class is Archaeopteryx lithographica, from the Late Jurassic period. According to the most recent consensus, Aves and a sister group, the order Crocodilia, together form a group of unnamed rank, the Archosauria. Phylogenetically, Aves is usually defined as all descendants of the most recent common ancestor of modern birds (or of a specific modern bird species like Passer domesticus), and Archaeopteryx. Modern phylogenies place birds in the dinosaur clade Theropoda. Modern birds are divided into two superorders, the Paleognathae (mostly flightless birds like ostriches), and the wildly diverse Neognathae, containing all other birds.

World Swordfish Fisheries
Author: Commerical Fishing
Author: G. MoorePublisher: John Wiley & Sons
ISBN: 0470694858
Category : Science
Languages : en
Pages : 74
Book Description
Fishing provides food, income and employment for millions of people. However, fishing has environmental costs that threaten rare species, marine ecosystems and the sustainability of the resource. Based on the research expertise of leading scientists, Commercial Fishing: the Wider Ecological Impacts provides a lively, timely and accessible account of fishing activities and their impacts on marine habitats, biodiversity and species of conservation concern. It covers fishing methods that range from trawling in the Antarctic to fishing with dynamite in the tropics. The authors show how habitats such as the muddy sea beds of the deep sea, kelp forests and coral reefs are affected by fishing and how birds, mammals, turtles and sea snakes both suffer and benefit from fishing activities. They also look to the future, highlighting ways to make fishing gear 'environmentally friendly' and asking whether marine reserves will improve conservation.
