A concise but comprehensive introduction to the biology of standing waters (lakes and ponds). As with other books in the Biology of Habitats Series, the emphasis in this book is on the organisms that dominate freshwater environments. Management and conservation aspects are also considered. The first edition of the book published in 1998 with a second, revised edition in 2005. There has been significant development in the field since the last revision appeared, particularly in the ecology of lakes and ponds in subtropical and tropical areas, and a new revision of this now classic text is timely.

Peatlands form important landscape elements in many parts of the world and play significant roles for biodiversity and global carbon balance. This new edition has been fully revised and updated, documenting the latest advances in areas such as microbial processes and relations between biological processes and hydrology. As well as thoroughly referencing the latest research, the authors expose a rich older literature where an immense repository of natural history has accumulated. The Biology of Peatlands starts with an overview of the main peatland types (marsh, swamp, fen, and bog), before examining the entire range of biota present (microbes, invertebrates, plants, and vertebrates), together with their specific adaptations to peatland habitats. Detailed coverage is devoted to the genus Sphagnum, the most important functional plant group in northern peatlands, although tropical and southern hemisphere peatlands are also covered. Throughout the book the interactions between organisms and environmental conditions (especially wetness, availability of oxygen, and pH) are emphasized, with chapters on the physical and chemical characteristics of peat, the role of peat as an archive of past vegetation and climate, and peatland succession and development. Several other key factors and processes are then examined, including hydrology and nutrient cycling. The fascinating peatland landforms in different parts of the world are described, together with theories on how they have developed. Human interactions with peatlands are considered in terms of management, conservation, and restoration. A final chapter, new to this edition, focuses on the role of peatlands as sources or sinks for the greenhouse gases carbon dioxide and methane, and the influences of climate change on peatlands. This timely and accessible text is suitable for students and researchers of peatland ecology, as well as providing an authoritative overview for professional ecologists and conservation biologists.

There is an increased awareness of the importance of polar regions, and their vulnerability to anthropogenic derived change. This book offers a concise but comprehensive introduction to polar ecology. The emphasis is on the organisms that dominate these environments although pollution, conservation and experimental aspects are also considered.

This book describes soft sediments in the sea and in estuaries as habitats for a wide range of animals and plants and techniques used to study them. Designed to be accessible to readers at all levels, it discusses organisms and their adaptations on sandy shores, mudflats, seagrass beds, salt marshes, mangrove swamps and below the tide marks. It emphasizes the special characteristics of estuaries, including life in the estuarine water column and estuarine food webs, and considers pollution problems and conservation approaches.

Clonal animals, that is those that are genetically identical, are of great importance in biology. The supposed evolutionary advantages of sexual versus asexual reproduction are one of the central paradoxes of current evolutionary theory. The evolved strategy of asexual reproduction includes a large number of diverse species in many different groups, for example aphids, guppies, planktonic rotifers and others.
