Fish Swimming
Among the fishes, a remarkably wide range of biological adaptations to diverse habitats has evolved. As well as living in the conventional habitats of lakes, ponds, rivers, rock pools and the open sea, fish have solved the problems of life in deserts, in the deep sea, in the cold antarctic, and in warm waters of high alkalinity or of low oxygen. Along with these adaptations, we find the most impressive specializations of morphology, physiology and behaviour. For example we can marvel at the high-speed swimming of the marlins, sailfish and warm-blooded tunas, air-breathing in catfish and lung fish, parental care in the mouth-brooding cichlids and viviparity in many sharks and toothcarps.

Avian Flight
Avian Flight covers all the main aspects of aerial locomotion by birds including sections on the history of thinking about bird flight, aerodynamics, functional morphology, evolution, kinematics, physiology, energetics and the cost of flight. The subject is complex and still not yet fully understood, and the author argues a convincing case for rethinking or even abandoning some of the old, well-established concepts.
The Secret of the Deceiving Striped Lizard... and More!
Students will learn all about intriguing adaptations that help animals survive in their environments, such as what playing a video game can teach us about striped lizards, the power of the chameleons sticky tongue, how wriggling and slashing saves frog eggs, a good partnership between sweet plants and ants, and the secret of the swordfishs slippery head. Primary sources include interviews with scientists and original photos. Engaging yet simple language makes complicated scientific principles easy to grasp. A hands-on activity allows students to take on the role of scientist and examine these amazing adaptations themselves.
Pike
Pike and related fish form an important part of aquatic ecosystems and are also commercially very valuable. This title provides full coverage of the biology, ecology and exploitation of this important group of fish and will be invaluable for fisheries scientists, fish biologists, aquatic scientists, ecologists and environmental scientists.
Managing Performance in the Public Sector
Topical and taking a bold stance in the contentious debate surrounding performance in the public sector, this new edition shows readers how performance thinking has a substantial impact on the management of public organizations. Thoroughly revised and updated, this highly successful text, written by an experienced academic and practitioner is packed full with a wealth of new features. These include: more examples and cases, from a variety of different sectors, including, hospitals, courts, school and universities a whole new chapter on the dynamics of performance management; answering the questions – how do PM systems evolve? Which effects will dominate in the long run? many extra recommendations for making PM attractive for managers. An informed and up-to-date analysis of this subject, this is an essential text for all those studying, both at undergraduate and postgraduate level, performance management in the public sector.
Behavior of Marine Fishes
BEHAVIOR OF MARINE FISHES BEHAVIOR OF MARINE FISHES: Capture Processes and Conservation Challenges Understanding fish behavior in relation to capture processes in marine fisheries is of fundamental importance to reducing bycatch and discards, and to enhancing marine fisheries conservation efforts. A thorough understanding of this allows commercial fishers to more effectively capture target species while reducing the catch of unwanted species. Behavior of Marine Fishes: Capture Processes and Conservation Challenges provides the reader with principles, patterns, and characteristics on fish behavior and fish capture processes using several types of important commercial fishing gears. The book a...
On the Sex of Fish and the Gender of Scientists
Daniel Pauly is the most widely cited fisheries scientist of his generation. On the Sex of Fish and the Gender of Scientists comprises an edited and updated collection of 27 of Daniel Pauly's essays, spanning a great range of exciting and sometimes controversial topics, many of them breaking new scientific ground.
Fish and Fisheries in Tropical Estuaries
Tropical estuaries are among the most modified and threatened of aquatic environments, supporting innumerable fisheries essential to the regions in which they occur. This book synthesizes the wealth of data available in this area, much of it being brought together by Stephen Blaber for the first time. It will provide readers with a comprehensive understanding of the fishes, the environments in which they live, and the management of biologically healthy estuaries and sustainable fisheries.
Air
We take it for granted, but without it we perish and if we continue to abuse it, it may kill us in the end. This fascinating text provides an understanding and appreciation of the role that air plays in our environment and its importance in relation to human life and technology. Aimed at those who are scientifically curious but who have no specialist training, it contains no mathematical equations and relies upon the qualitative descriptions and analogies to explain the more technical parts of the text together with simple home experiments to illustrate a range of air-based phenomena. Liberally illustrated with a range of line drawings and photographs, it recommends further reading for those who are motivated to learn more. This book offers invaluable background reading for both physics teachers and students. - Provides an understanding and appreciation of the role that air plays in our environment and its importance in relation to human life and technology - An introductory text for those who are scientifically curious but have no specialist training - Delivers qualitative descriptions and analogies and simple experiments that illustrate a range of air-based phenomena
