This book provides an invaluable, comprehensive and practical introduction to conservation issues associated with current farming practice. Representing both industry and conservation as an integrated and holistic system, it explores conservation issues within every farming discipline; from arable and horticulture to grasslands, woodlands, aquatic and coastal farming and will include an assessment of the impact of global warming.
The output from world aquaculture, a multi-billion dollar global industry, continues to rise at a very rapid rate and it is now acknowledged that it will take over from fisheries to become the main source of animal and plant products from aquatic environments in the future. Since the first edition of this excellent and successful book was published, the aquaculture industry has continued to expand at a massive rate globally and has seen huge advances across its many and diverse facets.
"Crocodiles" is an examination of the crocodile and its history which stretches back over 200 million years, linking the present day with the vanished age of dinosaurs. A succession of fossil forms traces the descent of modern crocodiles back almost to the beginning of the dinosaur age and demonstrates extinct groups that became, at one extreme, fully aquatic, converting their limbs into paddles (the metriorhynchids), or, at the other extreme, almost totally terrestrial, apparently seeking their prey entirely on land (the sebecids).
From the ocean depths to river rapids, fascinating aquatic life can be found in all climates and settings. Geared toward young students, the fresh, new "Exploring the World of Aquatic Life" set is packed with information, naturalistic artwork, helpful maps, and stunning full-color photography intended to illustrate key life-science principles while providing thorough information on the fish, mammals, and invertebrates that live a largely aquatic life.
Fractals and Multifractals in Ecology and Aquatic ScienceProvides an Intuitive View of Various Ecological Patterns and Processes
Ecologists sometimes have a less-than-rigorous background in quantitative methods, yet research within this broad field is becoming increasingly mathematical. Written in a step-by-step fashion, Fractals and Multifractals in Ecology and Aquatic Science provides scientists with a basic understanding of fractals and multifractals and the techniques for utilizing them when analyzing ecological phenomenon.
