distribution, physiological and anatomical specializa-tions, behaviour, reproduction, trophic relationships,community structure, systematics and evolution. Forexample, the amphibious blennies (Blenniidae) emergefrom water when dissolved oxygen is critically low.While on land, enlarged blood vessels near skin surfacesenable them to breathe air and their gills are kept moistby specially adapted gill chambers that retain water.Elongated and compressed body shapes allow somespecies to slip into wet crevices in rocks and under seaweedwhile the tide is out. Pectoral ®ns modi®ed into suckers inthe cling®shes (Gobiesocidae) are adaptations to the oftenturbulent conditions in exposed rocky coasts.Historically, resident intertidal ®shes have received

little research compared to intertidal invertebrates andplants; hence, the authors stress the need for moreresearch. They pose a wealth of hypotheses that willbene®t graduate students and research biologists, stimu-late more studies and, hopefully, greater conservationand appreciation of these intriguing ®shes. For example,the authors indicate a lack of consideration given tointertidal ®shes in management of coastal areas, despitetheir high vulnerability to exploitation, pollution, andtrampling by humans. No studies have examined thee�ects of ocean warming on intertidal ®shes and theirhabitats, and little knowledge exists on the e�ect ofhuman perturbations on their populations.

I feel the authors have missed an opportunity toinclude a discussion highlighting the importance of ®shesin the diets and bioenergetics of wildlife that forage in theintertidal, such as the wading birds. This analysis couldillustrate the interconnectedness of intertidal ®shes withvisible wildlife and valued human pursuits such as wild-life observation. Such information would be importantto resource biologists, managers and planners, whoshould be knowledgeable of the broader ecosystemvalues of intertidal and coastal areas, of which ®shes arean important part. However, the authors of IntertidalFishes are commended for writing the ®rst comprehen-sive text that I am aware of on the ecology of ®shes thatinhabit the intertidal.Their work will serve as an excellent reference and

springboard for new and exciting studies and ultimatelymore historic management and conservation of ourvaluable marine ecosystems.

Environmental Science for Environmental ManagementEdited by Timothy O'Riordan. Prentice Hall, Harlow,2nd Edition 1999. 520 pp. ISBN 0 582 35633 4 (pbk)Price £22.89

Those familiar with the ®rst edition will know thatthis is neither a systematic introduction to the sciencesrelevant to understanding the environment nor a hand-book of environmental management techniques. Ratherit is exempli®cation of a holistic and interdisciplinaryapproach to environmentalism, based on a solidknowledge base, whose practitioners are capable ofcontributing to and commenting on policy and decisionmaking Ð `the reuni®cation of science to policy.. in ademocratic.. society', as O'Riordan puts it.The book is framed by an introductory chapter (by

the editor) and a ®nal chapter `Managing the GlobalCommons' (by O'Riordan and Andrew Jordan), whichtogether set an agenda for such a project. Chapters onThe Sustainability Debate (O'Riordan), Environmentaland Ecological Economics (Neil Adger) and Environ-mental Politics and Policy Processes (Jordan andO'Riordan Ð new in this edition), introduce and eluci-date key issues which underpin the environmental

debate and inform the rest of the book. The secondedition has been extensively revised, redesigned, exten-ded (from 369 to 520 pages), and partly re-authored,but it still draws on the wide-ranging expertise of thesta� at the University of East Anglia. Each chapter has aneditorial introduction, providing a linking element to thevolume as a whole and up-to-date bibliographies ofrather variable lengths, some of which contain referencesto relevant web sites. Examples are `boxed' and this aidsthe ¯ow of the written text. There are cross referencesbetween chapters, but this does not identify the speci®cparts of chapters and ®nding the exact links which theauthors or editor envisaged can be frustrating.Seven case studies (in a total of 19 chapters) have

been retained from the ®rst edition: Soil Erosion andLand Degradation, River Processes and Management,Ground Water Pollution and Protection, Marine andEstuarine Pollution, Urban Air Pollution and PublicHealth, Preventing Disease, and Environmental RiskManagement. The scope of these chapters remainsessentially the same as in the ®rst edition but they havebeen rewritten to varying degrees and the opportunityhas been taken to up-date them, particularly with theinclusion of more recent examples. Five chapters in the

®rst edition have been dropped Ð the threat of globalwarming, predicting sea level rise and managing theconsequences, the oceans from space, the land fromspace and energy: hard choices ahead, but material andideas from them have been incorporated elsewhere, forexample in new chapters of Managing the Oceans,Waste Management, and Climate Change. This latter,authored by O'Riordan gives a good ¯avour of the casestudy chapters as a whole. He outlines the key elementsof the case for an enhanced, anthropogenic greenhousee�ect, but also raises the alternative sunspot explana-tion of global warming. He then considers brie¯y possi-ble impacts, adaptations to and mitigation of such ane�ect, and discusses the con®dence limits of our under-standing both of the science and the possible impacts.The remaining two thirds of the chapter emphasises thepolicy issues and processes associated with the econom-ics, politics and ethics of climatic change.In addition to environmental politics and policy pro-

cesses there are three other completely new chapters.Paul Dolman writes on Biodiversity and Ethics, brie¯yde®ning biodiversity and reviewing its attrition byhumans but then considers at greater length the di�er-ent cases that can be made for the `value' of biodiversityand the consequences of these for approaches to biodi-

versity conversation. Adger and O'Riordan take on thedi�cult task of discussing population growth and itsrelation to food resources in twenty pages, but do initi-ate a useful introduction to issues of vulnerability,adaptation and resilience. Andrew Lovetts' chapter onGIS and environmental management concentrates onan introduction to techniques and their possible appli-cations to environmental decision making.Anyone with a copy of the ®rst edition will ®nd

enough that is new here to justify buying the second.The book has a very broad scope and while each chap-ter raises complex issues, topics are inevitably coveredat an introductory level. It will provide excellent startingpoints for many undergraduate essays. However, stu-dent purchase will probably depend on the suitability ofthe approach of this book to the particular courses theyare studying, but if this reviewer's experience is anythingto go on multiple library purchases will be well justi®edand the books heavily used. The book also deserves tobe read widely outside the academic community.
