Seaweeds of Britain and Ireland


Book Description

The cool temperate waters of the British and Irish seas contain an astonishing 6% of the world’s algal species, more than 600 different seaweeds, and yet most divers, snorkellers and rockpoolers can put names to only a handful of them. The first edition of Seaweeds of Britain and Ireland has proved invaluable to an enormous number of people, not just volunteer Seasearch divers and snorkellers, and this eagerly awaited second edition will no doubt prove to be equally as popular. The aim of this book is to introduce the reader to the wonderful marine environment around Britain and Ireland, and improve identification of the wealth of seaweeds so often overlooked. Features of the new edition include: ● Over 230 species described in detail with colour photographs, information on size, habitat and distribution maps ● Over 50 new species, many with information on how to identify to species level using microscopic features ● Key distinguishing features and areas of identity confusion highlighted ● Colour and form used to group species and aid identification using dichotomous keys ● Details of life histories and reproductive processes for the main seaweed groups ● Both scientific and English names used for species and groups ● A glossary of common and specialised terms







A Rehabilitated Estuarine Ecosystem


Book Description

The well documented history of pollution and recovery in the Thames Estuary has made the system one of the world's most famous case studies. However, the story is incomplete in terms of the status of the rehabilitated ecosystem resulting from the remedial management policies. What ecosystem might we expect to recover from a once lifeless estuary? have the extensive efforts made by policy makers, environmental managers and scientists resulted in a diverse, complex estuary that may be a model for other systems? This book draws together many detailed aspects of the recovering Thames Estuary ecosystem from environmental management and scientific sources. The result is probably the most comprehensive account of the management and ecology of a single estuarine system yet produced. It includes important and extensive long term studies of the fish communities, water quality and management policy, spatial accounts along the full length of the estuary for benthic invertebrates and algae, significant case studies on zooplankton, saltmarshes and parasitology, as well as an overview looking forward to the next millennium. Altogether, this study of the long term ecological consequences of management policy provides a benchmark for comparison with other estuarine ecosystems, both `natural' and rehabilitated, and forms a unique and valuable reference for environmental managers, estuarine scientists and ecologists.




Evolutionary Biogeography of the Marine Algae of the North Atlantic


Book Description

Algal systematists, geologists and evolutionary biologists provide a synthesis of the evolutionary biogeography of red, brown, and green algae of the North Atlantic Ocean also considering their relationships with species and genera in the Arctic and Pacific Oceans as well as other subtropical and tropical seas. The history of the Atlantic Basin and its connections to other ocean basins is treated from the geological, paleontological and paleoclimatic perspective. This is contrasted with biogeographic analyses of marine animal systems and the role of plant/animal interactions in evolution. Some of the approaches include traditional systematic studies, cladistic analysis, the experimental evaluation of environment in establishing distribution limits and the application of molecular biology.




Brown Seaweeds (Phaeophyceae) of Britain and Ireland


Book Description

Brown Seaweeds (Phaeophyceae) of Britain and Ireland provides the first complete, up-to-date, detailed illustrated guide and keys to the nearly 200 species of brown algae present around the coasts of Britain and Ireland. It is the culmination of over 30 years of field and laboratory studies by the author. Following an exhaustive introduction that covers the biology and ecology of brown seaweeds, a checklist of species is set out, followed by clear and user-friendly keys to the genera. Particular attention is then paid to providing detailed illustrations, and the volume holds more than 300 compound plates of line drawings and photographs in its extensive taxonomic treatment. Comprehensive information is given on the geographical and seasonal distributions, synonymy, morphology, anatomy, cytology, reproduction, life histories, taxonomy, systematics and bibliographic material pertaining to each species. Notably, this flora offers a much fuller consideration of many of the lesser known, more cryptic microscopic brown algae than previously available. Further, the book also contains the results of much original research undertaken by the author. This will surely remain a standard reference work on brown seaweeds for many years to come – an indispensable research tool and field guide for phycologists and students throughout the North Atlantic region and beyond.




Rocky Shores


Book Description

An engaging account of the natural history of rock and boulder-strewn shores around Britain's coastline. Rocky Shores explores the species, communities and landscape of the narrow strip of land surrounding much of the British Isles. While it may be limited in extent, this habitat is incredibly biodiverse, and this insightful book details all the patterns of marine life that might be encountered on sheltered and exposed shores, from the inhospitable splash zone to the repeatedly submerged lower shore, and everything in between. Comprehensive chapters accompanied by exceptional photographs cover various members of the rocky-shore community in turn: striking lichens that colourfully adorn the rocks; seaweeds that have sustained human settlements for millennia; mysterious and often spectacular worms and their relatives; molluscs with variously configured shells; spiny-skinned echinoderms that move using tube feet; arthropods that range from tiny marine insects to heavy-clawed crabs; and microscopic species that drift around at the mercy of the tides. Rock pools provide pockets of diversity dotted across the shore, while the strandline at the high-tide mark supports a unique assemblage of microbes and invertebrates that attracts a variety of birds and mammals. For anyone with a love of the shore – from the occasional rockpooler to avid naturalists – this book is a must for your collection.
