The Complex Lives of British Freshwater Fishes (Hardcover): Mark Everard The Complex Lives of British Freshwater Fishes (Hardcover)
Mark Everard; Illustrated by Jack Perks
R1,208 Discovery Miles 12 080 Ships in 9 - 17 working days

CHOICE 'Highly Recommended for all readers' June 2021 Vol. 58 No. 10 This stunningly illustrated book goes far beyond a run-of-the-mill nature guide. It explores the fascinating life histories of Britain's freshwater fishes, a group of animals which, despite their importance and ubiquity in our diverse still and flowing fresh waters, has before now been rarely regarded and respected as 'wildlife'. Our native fishes tend generally to be considered as simply something for anglers to catch or for people to eat, yet they work enormously hard for us. Author Mark Everard, avid nature-watcher, angler and scientist, shows how freshwater fish provide food, ornamentation, sport and cultural identity, and highlights their huge importance for conservation as part of the living ecosystems upon which we all depend. He dives into the mysteries moving below the surface of our rivers and lakes, bringing the wonderful and fascinating world of the diversity of British freshwater fish species into plain sight and into mind. This unique book features over 100 full-colour photographs by pioneering photographer and filmmaker Jack Perks, whose work has featured on BBC Springwatch, The One Show and Countryfile. The book is filled with technical detail useful to conservationists and biology students. Most importantly, it is also presented in an accessible, visually attractive and engaging manner that will appeal to anybody with an interest in the natural world: the conservation-minded public, the angling community, and our nation of wildlife enthusiasts. Whatever your background, this book will open your eyes to our freshwater fishy wealth, and the many ways in which it enriches our lives.

R3,673 Discovery Miles 36 730 Ships in 10 - 15 working days

This book presents the latest scientific views on resource use conflicts in the Arctic seas. The main areas of focus are the biological resources of Arctic seas vs. exploitation of oil and gas resources, and the conflicts in between. In addition, climate change is presented as a stressor, which both limits and facilitates the economic availability of resources in the Arctic. The book is divided into five parts. Part 1 examines Arctic ecosystems, resilience of the marine environment and possible conflicts between industrial sector and biological world. The focus of Part 2 is on transport infrastructure along the northern routes. Issues such as Arctic maritime operations, black carbon and unmanned aerial vehicles are considered. Part 3 focuses on resource use conflicts in Arctic seas and on the most recent threats in terms of Arctic oil and gas exploration, offshore logistics operations as well as transportation of oil and oil products. Discussions in Part 4 of the book are concentrated around social aspects and involvement of local communities. Tourism development, preservation of indigenous culture, engagement of communities on relevant Arctic issues, search and rescue in the cold marine environment are examples of questions raised. The book reviews Arctic-specific petroleum regulations, the state of preparedness to oil spill accidents in the region as well as the latest developments in oil spill response technologies and their limitations. Search and rescue operations are reviewed and how working in this harsh Arctic environment affects the ability of rescue technicians to perform the required technical skills. Part 5 considers the sustainability challenges arising from the marine resource exploitation. The focus is on the vulnerability of Arctic ecosystems to disturbance - both natural and anthropogenic.

Great Salt Lake Biology - A Terminal Lake in a Time of Change (Paperback, 1st ed. 2020): Bonnie K. Baxter, Jaimi K. Butler Great Salt Lake Biology - A Terminal Lake in a Time of Change (Paperback, 1st ed. 2020)
Bonnie K. Baxter, Jaimi K. Butler
R5,157 Discovery Miles 51 570 Ships in 10 - 15 working days

Great Salt Lake is an enormous terminal lake in the western United States. It is a highly productive ecosystem, which has global significance for millions of migrating birds who rely on this critical feeding station on their journey through the American west. For the human population in the adjacent metropolitan area, this body of water provides a significant economic resource as industries, such as brine shrimp harvesting and mineral extraction, generate jobs and income for the state of Utah. In addition, the lake provides the local population with ecosystem services, especially the creation of mountain snowpack that generates water supply, and the prevention of dust that may impair air quality. As a result of climate change and water diversions for consumptive uses, terminal lakes are shrinking worldwide, and this edited volume is written in this urgent context. This is the first book ever centered on Great Salt Lake biology. Current and novel data presented here paint a comprehensive picture, building on our past understanding and adding complexity. Together, the authors explore this saline lake from the microbial diversity to the invertebrates and the birds who eat them, along a dynamic salinity gradient with unique geochemistry. Some unusual perspectives are included, including the impact of tar seeps on the lake biology and why Great Salt Lake may help us search for life on Mars. Also, we consider the role of human perceptions and our effect on the biology of the lake. The editors made an effort to involve a diversity of experts on the Great Salt Lake system, but also to include unheard voices such as scientists at state agencies or non-profit advocacy organizations. This book is a timely discussion of a terminal lake that is significant, unique, and threatened.

This book offers a comprehensive review of the current environmental conditions and chemical changes in Polish surface waters. Poland is situated in an area that was covered by glaciations in the distant past. The subsequent periods of glacial advance and retreat produced a continuous rejuvenation of the landscape, and the discharge of surplus water from this area was constantly transformed by morphological, climatic and hydrological changes. Written by expert contributors, the book's respective chapters address the impact of current climatic conditions on the functioning of surface water reservoirs in Poland, while also exploring the country's hydrographic and hydrological network and the trophic state of its rivers and lakes, their eutrophication and threats. Particular attention is paid to sources of pollution, above all, the chemical pollution of water and sediments. Together with the companion book Polish River Basins and Lakes - Part II: Biological Status and Water Management, it provides students, environmental chemists, biologists, geologists, hydrologists and surface waters managers with authoritative information on Poland's current environmental status.
