Healthy waterways and oceans are essential for our increasingly urbanised world. Yet monitoring water quality in aquatic environments is a challenge, as it varies from hour to hour due to stormwater and currents. Being at the base of the aquatic food web and present in huge numbers, plankton are strongly influenced by changes in environment and provide an indication of water quality integrated over days and weeks. Plankton are the aquatic version of a canary in a coal mine. They are also vital for our existence, providing not only food for fish, seabirds, seals and sharks, but producing oxygen, cycling nutrients, processing pollutants, and removing carbon dioxide from our atmosphere. This Second Edition is a fully updated introduction to the biology, ecology and identification of plankton and their use in monitoring water quality. It includes expanded, illustrated descriptions of all major groups of freshwater, coastal and marine phytoplankton and zooplankton and a new chapter on teaching science using plankton. Best practice methods for plankton sampling and monitoring programs are presented using case studies, along with explanations of how to analyse and interpret sampling data. The book is an invaluable reference for teachers and students, environmental managers, ecologists, estuary and catchment management committees, and coastal engineers

Nombre d'économistes et de géographes contestent la pertinence des Sciences de la Nature dans les études de Développement. Pour beaucoup le concept de tropicalité n'a guère de réalité. Et pourtant la spécificité du monde intertropical est d'une évidence troublante : un "Monde sans hiver" (1993) du botaniste Francis HALLÉ vient de le rappeler avec bon sens. Le domaine tropical regroupe plus de 65 % de la population mondiale et la majorité des pays pauvres sur 40 % des terres émergées. La plupart des ressources fossiles (charbon, pétrole, métaux) se sont élaborées en conditions tropicales. Le monde tropical concerne donc tous les hommes. En privilégiant les études de terrain et l'intérêt des marqueurs de l'évolution des milieux, les auteurs montrent l'infinie variété des environnements tropicaux et des comportements. Mais la déstabilisation anthropique des milieux s'est accélérée au cours du XXe siècle. Sont mis en évidence les enregistreurs et les indicateurs des évolutions à court et à long terme : milieux de dépôts, indicateurs des sols et de la végétation, ressources en eau, crises climatiques et rurales, littoraux et montagnes. Cette vision résolument géographique et à long terne s'oppose à une vision économiste et à courte vue, imposée par le système financier mondial. La gestion de notre Environnement devrait-elle se soumettre aux stratégies de Développement comme le suggèrent certaines conclusions du Sommet de Rio ? L'homme a peu à peu domestiqué les paysages tropicaux, sans pour autant gommer leur spécificité. Notre environnement s'adapte en permanence, avec ou sans l'Homme, depuis des millions d'années. Si l'Homme veut conserver sa place, il ne doit pas se laisser entraîner par l'utopie d'un "possibilisme" régi par les intérêts immédiats des pays riches. Plus que jamais Environnement et Développement sont liés. En effet la croissance démographique des pays tropicaux et ses conséquences pour la survie de l'Humanité dépendront d'une gestion à long terme de…

Environmental indicators, such as global temperatures and pollutant concentrations, attract scientists' attention and often make the headlines. Equally important to policymaking are indicators of the ecological processes and conditions that yield food, fiber, building materials and ecological "services" such as water purification and recreation.This book identifies ecological indicators that can support U.S. policymaking and also be adapted to decisions at the regional and local levels. The committee describes indicators of land cover and productivity, species diversity, and other key ecological processes--explaining why each indicator is useful, what models support the indicator, what the measured values will mean, how the relevant data are gathered, how data collection might be improved, and what effects emerging technologies are likely to have on the measurements. The committee reviews how it arrived at its recommendations and explores how the indicators can contribute to policymaking. Also included are interesting details on paleoecology, satellite imagery, species diversity, and other aspects of ecological assessment. Federal, state, and local decisionmakers, as well as environmental scientists and practitioners, will be especially interested in this new book.

"Integrating research into freshwater biodiversity and the role of keystone species, this fascinating book presents freshwater crayfish as representatives of human-exacerbated threats to biodiversity and conservation. It uses examples from these and other large decapod invertebrates to explore how communities function and are controlled, alongside the implications of human demands and conflicts over limited resources, notably the severe impacts on biodiversity. The discussion is structured around three key topics - the present situation of crayfish in world freshwater ecosystems, the applications of science to conservation management and knowledge transfer for successful crayfish management. It outlines the historic exploitation of crayfish, addressing the problems caused by invasive alien forms and explaining the importance of correct identification when dealing with conservation issues. Offering a global perspective on freshwater systems, the book ultimately highlights how the conservation of such large and long-lived species will help protect ecosystem quality in the future"--
