Book Description
Hitherto, there has been no way to identify Canadian and US seed samples except to compare them with known specimens. Identification has been a process of elimination depending on the experience, knowledge, and memory of the observer. The Seeds and Fruits of Plants of Eastern Canada and Northeastern United States describes and illustrates the seeds of about 1100 species of native wild and introduced weedy plants from some 118 families, and provides keys for their identification based on their geometric shapes. The primary tool used in describing the shape of the seeds and keying them is the chart of symmetric plane figures developed by the Systematics Association Committee of the International Association Plant Taxonomy. That seeds, which were obtained from herbaria or the author's own collection, were thus sorted and classified according to the exact shape of their longitudinal and cross sections to form the major sections of the key. Morphological details, observed under magnifications up to 30 x, were then used both for minor separations in the key and in describing species. Photography was chosen as the most accurate means of illustration. While primarily intended for taxonomists and those teaching seed identification, as a text and for verification of identifications, this book will also be an important reference for studies of archaeology studying seed remains, ecologists studying bog formations, and see analysts both in Canada and the US.

The second revised edition of the Encyclopedia of Quaternary Science, Four Volume Set, provides both students and professionals with an up-to-date reference work on this important and highly varied area of research. There are lots of new articles, and many of the articles that appeared in the first edition have been updated to reflect advances in knowledge since 2006, when the original articles were written. The second edition will contain about 375 articles, written by leading experts around the world. This major reference work is richly illustrated with more than 3,000 illustrations, most of them in colour. Research in the Quaternary sciences has advanced greatly in the last 10 years, especially since topics like global climate change, geologic hazards and soil erosion were put high on the political agenda. This second edition builds upon its award-winning predecessor to provide the reader assured quality along with essential updated coverage Contains 357 broad-ranging articles (4310 pages) written at a level that allows undergraduate students to understand the material, while providing active researchers with a ready reference resource for information in the field. Facilitates teaching and learning The first edition was regarded by many as the most significant single overview of Quaternary science ever, yet Editor-in-Chief, Scott Elias, has managed to surpass that in this second edition by securing even more expert reviews whilst retaining his renowned editorial consistency that enables readers to navigates seamlessly from one unfamiliar topic to the next
