The book covers the various aspects of the use of pesticides, their behavior, degradation, and impacts in wetland ricefields, and presents the results of surveys conducted in the Philippines and Thailand. It includes both bibliographic reviews and selected aspects of the experimental results of a research project on pesticide impacts in wetland ricefields. The first phase of the `Pesticide Impact' project was developed in the Philippines from 1989 to 1991. It was a multidisciplinary/collaborative approach involving scientists from IRRI, NRI (England), ORSTOM (France), UPLB (Philippines) who studied the effects of pesticides on the environment and on farmers' health, and the economical aspects of their use.

Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives. This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN. As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms. The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.

Upon its initial publication more than fifteen years ago, this book broke new ground with its comprehensive coverage of the biology and ecology, distribution and dispersal mechanisms, physiology, monitoring, negative and positive impacts, and control of aquatic invasive species of mussels, clams, and snails. Building on this foundation, the second edition of Monitoring and Control of Macrofouling Mollusks in Fresh Water Systems includes completely revised information on species such as the zebra mussel while also covering up-and-coming nuisance species such as the quagga mussel, Conrad’s false mussel, the Asian clam, and the fast-spreading golden mussel. The Second Edition includes: Ten new species of mussels and snails International case studies on mussel fouling problems and how to cope with them New control and monitoring techniques Discussions of the latest threats and possible future scenarios The book contains brief descriptions of the external and internal structures, examining only those features relevant to the monitoring and control of the invasive species. It discusses why the mollusks are pests, distinguishing nuisance species from native species, their habits and habitat, reproductive potential, and life cycles and population dynamics. The authors also explain how efficient dispersal mechanisms employed by the nuisance mollusks not only help them spread so rapidly to inland lakes and rivers across continents, but how they can invade virtually every part of a facility. While many other resources contain segments of this information, none cover all areas and link them in a cohesive fashion. It is this approach that makes the understanding of potential impacts on ecosystems, industries and utilities, as well as the many human-made physical and chemical mitigants for controlling the mollusks supplied by this book so crucial for preserving the health of raw water supplies.

Life itself as well as the entire human economy depends on goods and services provided by earth's natural systems. The processes of cleansing, recycling, and renewal, along with goods such as seafood, forage, and timber, are worth many trillions of dollars annually, and nothing could live without them. Yet growing human impacts on the environment are profoundly disrupting the functioning of natural systems and imperiling the delivery of these services.Nature's Services brings together world-renowned scientists from a variety of disciplines to examine the character and value of ecosystem services, the damage that has been done to them, and the consequent implications for human society. Contributors including Paul R. Ehrlich, Donald Kennedy, Pamela A. Matson, Robert Costanza, Gary Paul Nabhan, Jane Lubchenco, Sandra Postel, and Norman Myers present a detailed synthesis of our current understanding of a suite of ecosystem services and a preliminary assessment of their economic value. Chapters consider: major services including climate regulation, soil fertility, pollination, and pest control philosophical and economic issues of valuation case studies of specific ecosystems and services implication of recent findings and steps that must be taken to address the most pressing concerns Nature's Services represents one of the first efforts by scientists to provide an overview of the many benefits and services that nature offers to people and the extent to which we are all vitally dependent on those services. The book enhances our understanding of the value of the natural systems that surround us and can play an essential role in encouraging greater efforts to protect the earth's basic life-support systems before it is too late.

Mollusc species currently constitute a major threat to sustainable agriculture. This threat is associated with cultivation of new crops, intensification of agricultural production systems and the spread through human trade and travel of species adapted to these modified environments. In some crops their significance is only now becoming apparent with the decline in the importance of other pest groups which can be effectively controlled. The book focuses on: toxicology of chemicals; deployment of molluscicides in baits; specific crop situations worldwide; current pest status of mollusc species and progress towards development of solutions.

FREE THOUGHT, FAITH AND SCIENCE: FINDING UNITY THROUGH SEEKING TRUTH By Roger Pullin. This book covers a hot topic – can faith, defined as personal belief and trust in God and not as a religious affiliation, ever be compatible with science? Dr. Roger Pullin argues forcefully that faith and science are complementary paths to truth, with all truthful spiritual insights and all truthful disclosures through mathematics and science coming from God, and that through faith and science we approach one whole body of truth. He writes as a marine biologist with a long career in research, teaching and consulting, mostly in tropical developing countries, and as a believer. He is an Associate Member of Christians in Science and the Society of Ordained Scientists, a Member of the Science and Religion Forum and a Member and former Elder of the Union Church of Manila, Philippines. Dr. Pullin draws together threads from works across theology and science and from personal experiences to offer fresh perspectives on what he calls Free Thought. Free Thought has capital letters to distinguish it from our basic thought about the practicalities of life - what to eat, what to wear, how to dodge traffic etc. Free Thought is not freethinking, as defined conventionally by an outcome of dissent from some religious or other established order. No process defined by a specific outcome can be called free. Free Thought can have any outcome, including agnosticism, atheism and faith. Free Thought is founded on free will. Everyone is free to explore all available information and to choose what to believe. No one knows what anyone else truly believes. Free Thought is truly free. Every human self is a unique combination of a material mind-body with a spiritual soul. Free Thought is the integrated and iterative processing of information from the material and spiritual realms, in one or more common nonmaterial formats, across an individual mind-soul interface. Free Thought connects the material and spiritual realms in every person. Our Free Thought and mind-soul interfaces make us the agents by which God and the spiritual force for evil can bring about change in the material realm. The laws of nature are not suspended to allow so-called miracles. We have free will. The material realm works through free process. From this perspective, Dr. Pullin reviews the human condition, faith, science, the battlefields on which we seek truth in the midst of lies and nonsense and make moral choices, the need for reformations in organized religion and revolutions in science and the prospects for faith-science unity. He recommends expansion of faith-science quest for truth, by scientific appraisals of subjective evidence from within believers and nonbelievers and by considering the implications of a spiritual realm for brain and consciousness research and a theory of everything. This book’s 11 chapters can be adapted as a series of lectures. It depicts a model and mechanisms for Free Thought in a 6-part Figure 1, the backdrop to which forms the cover design, and a synthetic Figure 2. Its 5 Appendices provide definitions of terms, summaries of the author’s beliefs and background, reviews of related literature and a questionnaire for readers. Its total length is 431 pages, plus a user-friendly Index.

The Ecology of Java and Bali is a comprehensive ecological survey of two of the most ecologically diverse islands in the Pacific. It also contains the results of original research, interviews and personal experience. It will be useful to resource managers, ecologists and government planners, as well as to all others interested in the region. Java and Bali are the best known of all the islands in the Indonesian archipelago. Nowhere else in the country are ecological issues of such importance, and nowhere else is there a better chance of the major development problems being solved. This is because Java has the greatest concentration of development projects, the densest population, excellent human resources, and the interest of many of the most powerful decision makers. Bali, meanwhile, has the eyes of the world on it as an important tourist destination enjoyed by both domestic and foreign visitors.
