Book Description
New Zealand has a rich and varied assortment of rivers, streams, lakes and wetlands that are home to a modest but really fascinating and varied freshwater fish fauna. For many years this fauna was known to only a small group of specialists and devotees but, over the past few decades, an increasing number of naturalists, conservationists and anglers have begun to discover the attractions and fascination of these fishes. The Reed Field Guide to New Zealand Freshwater Fishes is a complete and easy-to-read reference to the fishes throughout New Zealand and her outlying islands, such as the Chathams. Each entry contains colour photographs, a line drawing and a distribution map and information on size, colour, features particular to the type of fish, distribution, habitat and diet.

Book Description
In many ways, this book is the culmination of more than four decades of my exp- ration of the taxonomy, biogeography and ecology of New Zealand’s quite small freshwater fish fauna. I began this firstly as a fisheries ecologist with the New Zealand Marine Department (then responsible for the nation’s fisheries research and mana- ment), and then with my PhD at the Museum of Comparative Zoology at Harvard University, Cambridge, MA, USA in the early–mid 1960s. Since then, employed by a series of agencies that have successively been assigned a role in fisheries research in New Zealand, I have been able to explore very widely the natural history of that fauna. Studies of the fishes of other warm to cold temperate southern lands have followed, particularly southern Australia, New Caledonia, Patagonian South America, the Falkland Islands, and South Africa and, in many ways, have provided the rather broader context within which the New Zealand fauna is embedded in terms of geography, phylogeny, and evolutionary history, and knowing this context makes the patterns within New Zealand all the clearer. An additional stream in these studies, in substantial measure driven by the beh- ioural ecology of these fishes round the Southern Hemisphere, has been exploration of the role of diadromy (regular migrations between marine and freshwater biomes) in fisheries ecology and biogeography, and eventually of diadromous fishes wor- wide.

Book Description
Since the publication of The Migrations of Fish by Prof. Alexander Meek in 1916, a number of books have been published on this subject. However, most of these books only cover one type of migratory mechanisms. This book aims to overcome this drawback by presenting a comprehensive coverage of all life history strategies-potadromy, anadromy, catadrom

Book Description
New Zealand's most experienced bird photographer has now produced a splendid field guide to all the birds found on mainland New Zealand. The result of many years of pain staking fieldwork, the book contains more than 360 photographs and is the first photographic field guide to the birds of New Zealand. The information in the book includes both common and up-to-date scientific names, together with descriptions of each bird's habitat, distribution, physical characteristics, voice, diet and breeding habits. Where relevant, plumage differences between the sexes are illustrated. A glossary and a helpful section on bird watching equipment complete an invaluable field guide that no bird watcher, tramper, nature enthusiast or photographer will want to be without.

Book Description
Brown Trout: Biology, Ecology and Management A comprehensive guide to the most current research, history, genetics and ecology of the brown trout including challenging environmental problems The brown trout is an iconic species across its natural European distribution and has been introduced throughout the World. Brown Trout offers a comprehensive review of the scientific information and current research on this major fish species. While the brown trout is the most sought species by anglers, its introduction to various waters around the world is causing serious environmental problems. At the same time, introduction of exogenous brown trout lineages threats conservation of native gene pools of populations in many regions. The authors summarize the important aspects of the brown trout’s life history and ecology and focus on the impact caused by the species. The text explores potential management strategies in order to maintain numerous damaged populations within its natural distributional range and to ameliorate its impacts in exotic environments. The authors include information on a wide-range of topics such as recent updates in population genetics, evolutionary history, reproductive traits and early ontogeny, life history plasticity in anadromous brown trout and life history of the adfluvial brown trout and much more. This vital resource: Contains the latest research on the biology and ecology of brown trout Includes information on phylogeography, genetics, population dynamics and stock management Spotlights the brown trout’s introduction to regions around the world and the serious environmental impacts Offers a comprehensive review of conservation and management techniques Written for salmonid scientists and researchers, fishery and environmental managers, and students of population genetics, ecology and population dynamics, Brown Trout explores the most recent findings on the history, ecology and sustainability of this much-researched species.

Book Description
The globalization of trade, monetary and fiscal policies, capital markets, and investment patterns is reshaping the world economy and is leading to new financial, commercial, and marketing structures as well as unprecedented economies of scale. Simultaneously, national and international awareness and to strengthen. There is consensus among responses to accelerating environmental degradation continue most developed countries that the rapidly evolving new economic order needs to be well integrated with policies to maintain or restore environmental quality. Many challenges remain, however, in evaluating the geo-ecological implications of economic globalization, and in formulating the appropriate management responses. In lakes and rivers, the management of water supply and quality has largely proceeded on the basis of local considerations rather than at the global scale that has been more typical of environmental management of the atmosphere and ocean. It is increasingly apparent, however, that high-quality water resources are now in critically short supply not only because of local problems such as over-irrigation and eutrophication, but also as a result of larger-scale climate effects on the hydrosphere. This magnitude of impact will increasingly require the integrated monitoring and management of water resources on a planetary scale, with world criteria for environmental assessment, restoration, and conservation strategies. The increasing extent of world trade in potable freshwater heightens the urgency for establishing international approaches, criteria, and regulations.

Book Description
Diver, undersea explorer and passionate conservationist Wade Doak has lived near the Tutukaka coast with wife Jan since 1968. Well known for his pioneering dives at the Poor Knights Islands off the coast of Whangarei, Wade has gradually shifted his focus over the years from the sea to the land. He and Jan have spent years exploring the shoreline and estuaries, walking cliff-top paths, studying the mangroves and roaming the forest. Wade's engaging text tells a remarkable story, illustrated with an incredible photographic archive of trees, shrubs, vines, orchids, ferns, birds, and attendant wildlife, displaying an area rich in diversity. With intensive pest control, the Doaks have witnessed a dramatic recovery of the native flora and fauna. In 'their coastal slice' the natural world has returned with a profusion of birdsong in the forest. This book is a plea for the conservation and protection of New Zealand's wildernesses, reiterating the challenge made by Sir Paul Callaghan: can we eradicate pests throughout our island nation? On a small scale, Wade and Jan Doak show that yes, it can be done.
