Dytiscid beetles comprise a large element within the Canadian fauna yet their identification is difficult for the nonspecialist and the distribution and habitats of the species are only sketchily known. The initial and continued aims are to make the predaceous water beetle fauna of Canada accessible to as wide an audience as possible by summarizing available knowledge of the fauna, documenting the species present and their distribution and habitats, providing means for the identification of the taxa, and indicating where knowledge is especially lacking and where interesting and possibly productive research avenues lie. To achieve these aims it has been necessary to revise several genera, review the systematic position of many taxa and to seek out immature stages of various taxa. Much new information, including descriptions of new taxa, is included here. This work will aid and encourage others to look at water beetles with increased interest and appreciation and will stimulate research on these as yet poorly understood insects. The Canadian fauna cannot be understood without reference to the overall Nearctic fauna and therefore the scope gradually enlarged over time to include most of the North American fauna. This work treats all Nearctic genera and most species. Detailed treatment is provided for all species known from Canada. Non-Canadian species are treated as fully in some genera, in others these species are included only in keys. Only within genera where some species are too poorly known to allow their definition, are all species not included. The areas with the most incomplete coverage are both the Gulf States and southwestern United States, namely western Texas to southern California. For the rest of the continent, it is hoped that this work will provide a useful identification guide.

This unique book has an exciting story to tell about Ca[2], the versatile Master Cell Signaler whose influence reaches into all corners of the cell and controls cell proliferation, differentiation, cell functions too numerous to list here, and even cell death. The book begins nearly 4 billion years ago with the emergence of life on the newborn Earth. One of the great turning points in the history of life on Earth, The Great Ca[2+]-Driven Eukaryotic Revolution, happened about 2 billion years later when Ca[2+] was converted from a dangerous killer that had to be kept out of cells into the versatile Grand Master of cell signalers. It was this revolutionary conversion that enabled the development of eukaryotic cells from which came animals with shells, internal and external skeletons, muscles and brains, and, of course, the plants. The reader will be taken on a tour of tissues chosen to best show three (proliferator, differentiator, killer) of Ca[2+1]s many faces.

The first edition, by P.R. Bunker, published in 1979, remains the sole textbook that explains the use of the molecular symmetry group in understanding high resolution molecular spectra. Since 1979 there has been considerable progress in the field and a second edition is required; the original author has been joined in its writing by Per Jensen. The Material of the first edition has been reorganized and much has been added. The molecular symmetry group is now introduced early on, and the explanation of how to determine nuclear spin statistical weights has been consolidated in one chapter, after groups, symmetry groups, character tables and the Hamiltonian have been introduced. A description of the symmetry in the three-dimensional rotation group K(spatial), irreducible spherical tensor operators, and vector coupling coefficients is now included. The chapters on energy levels and selection rules contain a great deal of material that was not in the first edition (much of it was undiscovered in 1979), concerning the Jahn-Teller effect, the Renner effect, Multichannel Quantum Defect Theory, the use of variational methods for calculating rotational-vibration energy levels, and the contact transformed rotation-vibration Hamiltonian. A new chapter is devoted entirely to weakly bound cluster molecules (often called Van der Waals molecules). A selection of experimental spectra is included in order to illustrate particular theoretical points.

Migmatites are highly heterogeneous rocks found in high-grade metamorphic environments; they are commonly encountered in the continental crust. Until now, many geologists have been deterred from working with migmatites because of their complex appearance and an unhelpful non-genetic nomenclature. In his "Atlas of Migmatites", Dr. Edward Sawyer provides genetically based definitions and a system of nomenclature with which it will be possible to describe and map migmatites effectively and to understand how combinations of factors and processes produce a bewildering morphological diversity. Migmatites are produced by partial melting; to aid the reader in the identification of migmatites, the author describes and illustrates microstructures that can be used to infer the presence of melt or a melt-producing reaction. He also describes how geochemical data can be used to infer petrological processes involved in migmatite development. This book includes the results from two decades of researc

This easy-to-follow, full-colour guide was created for instructors teaching plant structure at the high school, college, and university levels. It benefits from the experience of the authors, who in teaching plant anatomy over many years, came to realize that students learn best by preparing their own microscope slides from fresh plant samples. The exercises contained in this book have been tested, require minimal supplies and equipment, and use plants that are readily available. Detailed instructions are given for sectioning and staining of plant material. The book contains a glossary of terms, an index, and a list of suppliers of materials required. A CD-ROM of all the illustrations is included for easy downloading into PowerPoint presentations. "Although a number of new plant anatomy texts have been published in recent years, none is as innovative, exciting and user-friendly as "Teaching Plant Anatomy Through Creative Laboratory Exercises" by Peterson, Peterson and Melville. What makes this book so usable from high school biology courses on through to upper level university plant structure labs is the wealth of experience that the authors have incorporated into this comprehensive clearly illustrated text. Using mostly photomicrographs of hand sections and wonderfully clear colour illustrations, they cover all aspects of plant structure from organelles to organs. The book also outlines some easy to use techniques, such as hand sections and clearings and macerations, which will certainly be very useful for any plant related lab. This book really does bring plant anatomy to life and will be a must for any course that deals with plant structure even if it's just to prepare plant material for molecular techniques. An excellent contribution to any botanical teaching where you want your students to get a hands-on approach to the subject."... Dr. Usher Posluszny, University of Guelph

Environmentalists often voice concern about threats like acid rain, carbon dioxide buildup in the atmosphere, water contamination, and declining biodiversity. Recently, many have come to recognize another equally serious threat called biological pollution. Biological pollution is the movement of living organisms, either accidentally or intentionally, from the places where they evolved to new environments where a lack of natural enemies permits their population to explode. These organisms, sometimes called invasive exotic pests, threaten our crops, our forests, and perhaps even our very existence. Biological pollutants, like chemical pollutants, are here because of human activities. But unlike chemical pollutants, biological pollutants cannot be reduced or prevented by legislation. Once biological pollutants are imported, they grow, adapt, multiply and spread on their own unless direct, vigorous, and often costly actions are taken to stop them. This important book presents a broad spectrum of concerns in nontechnical language to conservation-minded people. The first three chapters provide general background on biological pollution, including insight into the enormity of the problem and the direct and indirect costs to date. The next section provides specific examples of exotic weeds, diseases, nematodes, and insects and the damage they cause. The last section examines the defenses in place and proposed improvements to resisting biotic invasion. Biological Pollution: An Emerging Global Menace is required reading for environmentalists, plant pathologists, horticulturists, weed scientists, nematologists, entomologists, foresters, agronomists and all others dedicated to protecting the environment. Anyone interested in natural resources and agriculture will gain valuable knowledge from this eye-opening publication.
