Book Description
'The criterion of true beauty' , wrote Fulke Greville, 1st Baron of Burke, 'is that it increases on examination; if false, that it lessens. There is therefore something in true beauty that corresponds with right reason, and it is not the mere creation of fantasy.' The authors of this compact volume have increased the beauty of an area that is commonly and rightly ac knowledged to be one of the loveliest parts of the Great Lakes. They have done this by integrating the historical, industrial, and cultural influences on 'Lake Manitoulin' in sixteen manuscripts. It is enigmatic that Lake Huron, the second of the Great Lakes to be discovered by European explorers, has been the last to be adequately described Iimnologicaliy. As recently as 1966, for example, Alfred M. Beeton wrote in Limnology in North America: ' ... even a list of the more common species comprising the plankton of Lake Huron could be an original contribution to scientific literature.' Comparable statements could have been made for sediments, benthos, and water chemistry. This volume reflects a change of course and Georgian Bay and the North Channel of Lake Huron are now on the scientific map. Science is 'right reason'. Its application to Georgian Bay and the North Channel is a welcome and timely addition for the renewal of public, political, and scientific interest in the conservation of the Great Lakes.

Book Description
This book discusses current knowledge and challenges with the ecological management and conservation of wetlands, with a focus on the East Kolkata Wetlands of India. This area is referred to as a Ramsar Site, a designation given to areas with special protection statuses, since it is the largest natural waste recycling system in the world. The site faces many threats to its biodiversity and ecosystem functioning due to anthropogenic activity in the region, and therefore an assessment of the ecosystem services, bio-ecological uniqueness, and issues stemming from climate change and human impacts is needed to develop protection strategies for the future ecological functioning and sustainability of the wetlands. The authors use GIS and remote sensing techniques to assess and monitor harmful industrial and environmental impacts on the wetlands, and to inform mitigation and conservation strategies in the face of ongoing threats such as pollution, habitat destruction and bioinvasion. The book also highlights various social and economic aspects tied to the functioning and management of the wetlands, along with ecological, biological, and physio-chemical considerations. The study will be of use to students and researchers in aquatic ecology, biodiversity, and environmental sustainability and conservation, as well as to environmental planners, engineers, and policymakers.

Book Description
The fundamental purpose of this book is to synthesise the divergent literature on aquatic lipids into a co-ordinated, digestible form. A large part of the book addresses lipid composition and production in freshwater organisms, with chapters on phytoplankton, zooplankton and benthic invertebrates. A common theme throughout the book is the function of lipids in aquatic food webs, with a chapter devoted exclusively to lipids as indicators of health in fish populations. A complementary chapter highlights the role of lipids and essential fatty acids in mariculture. Methodologies to determine the lipid content of aquatic samples and suggestions as to the utility of fatty acids as trophic markers are included, as is one chapter on the role of lipids in the bioaccumulation and bioconcentration of toxicants and another on the relationships between lipids and surface films and foams. The final chapter highlights the similarities and differences between lipids of marine and freshwater origin. Students and researchers in ecology, phycology, aquatic toxicology, physiological ecology and limnology will find this an invaluable guide and reference.
