Book Description
Tree-ring dating (dendrochronology) is a method of scientific dating based on the analysis of tree-ring growth patterns. As author James Speer notes, trees are remarkable bioindicators. Although there are other scientific means of dating climatic and environmental events, dendrochronology provides the most reliable of all paleorecords. Dendrochronology can be applied to very old trees to provide long-term records of past temperature, rainfall, fire, insect outbreaks, landslides, hurricanes, and ice storms--to name only a few events. This comprehensive text addresses all of the subjects that a reader who is new to the field will need to know and will be a welcome reference for practitioners at all levels. It includes a history of the discipline, biological and ecological background, principles of the field, basic scientific information on the structure and growth of trees, the complete range of dendrochronology methods, and a full description of each of the relevant subdisciplines. Individual chapters address the composition of wood, methods of field and laboratory study, dendroarchaeology, dendroclimatology, dendroecology, dendrogeomorphology, and dendrochemistry. The book also provides thorough introductions to common computer programs and methods of statistical analysis. In the final chapter, the author describes "frontiers in dendrochronology," with an eye toward future directions in the field. He concludes with several useful appendixes, including a listing of tree and shrub species that have been used successfully by dendrochronologists. Throughout, photographs and illustrations visually represent the state of knowledge in the field.

Book Description
Who would have thought that dwarf cedar trees growing on the Niagara Escarpment could live to be nearly 2000 years old. Or that the small bonsai cedars lining the shorelines of the Canadian shield measure their ages in centuries. Old growth pine trees in Temagami are often over 10 stories tall, but these are young sprouts compared to trees of yesteryear, which were as much as 20 stories high. Ontario's old growth forests are fantastical and mysterious, but who knows where to find one. Most people in this province live within an hour's drive of an old growth forest, but do not know it. The ecology of these stands is engrossing. Fire scars on these trees, for example, provide an indisputable record of forest fire activity in Ontario. Small hemlock saplings, over 100 years old, have been growing at infinitesimal rates, waiting for a gap to open in the forest canopy.

Book Description
Reviews literature concerning the effects of global climate change on forest plants and communities, and provides opinions on the potential impacts that climate change may have on Ontario forests. Sections of the review discuss the following: the climate of Ontario in the 21st century as predicted by climate models; forest hydrology in relation to climate change; insects and climate change; impacts on fungi in the forest ecosystem; impacts on forest fires and their management; plant physiological responses; genetic implications of climate change; forest vegetation dynamics; the use of models in global climate change studies; and forest management responses to climate change.

Book Description
It is enough to work on the assumption that all of the details matter in the end, in some unknown but vital way. Edward O. Wilson, Biophilia Advances in knowledge of northern ecology have been so rapid that to undertake a synthesis of all the literature now available would be a major enterprise, perhaps even a life's work, and so it must be considered permissible to fill in a few gaps, follow one's own inclinations, leaving comprehensive syntheses to those willing to undertake them. This is the rubric under which I have written, reporting some of the more interesting data I and others have obtained over the years, often diverging into discussions of plants, soils, climate, and faunal relationships which have perhaps not previously been dealt with extensively, or at least in quite the same way. This is purely intentional, since I find it difficult to summon up the needed enthusiasm, at this late hour, to write on topics which unfortunately for me have little attraction. I have thus written for the pleasure derived from depicting, perhaps at times as something of an impressionist, a fascinating biotic region, a captivating land, a collection of interesting ecological problems, environmental relationships to be discerned in part, perhaps understood to some small degree, perhaps one day to be modeled mathematically. As Leo Szilard once wrote: ': . . to be able to say even this much might be of some value" (Szilard, 1960).

Book Description
This book presents different perspectives on how to understand the complex interaction between plants and the environment. Plant communities adapt to biotic and abiotic stresses with different mechanisms and understanding these phenomena provides the means to better manage our environment and to cultivate crops that better serve our needs.

Book Description
In the opening chapters contributors lay out the large-scale context of the physical climate of Canada, introducing the processes, balances, and dynamic linkages between the surface and atmosphere that create and maintain the diversity of surface climates found in Canada as well as outlining the nature of the physical processes that operate near the ground's surface. Individual chapters are dedicated to snow and ice - the almost universal surface cover in Canada - and the other major natural surface environments of Canada: ocean and coastal zones, fresh water lakes, wetlands, arctic islands, low arctic and subarctic lands, forests, and alpine environments. The final part of the book considers those surface environments that have been strongly influenced by human activity, such as agricultural lands and urban environments, and examines the prospects for future climate change. Bringing together for the first time a wide range of scholarship by leading climatologists, The Surface Climates of Canada will be an indispensable tool for understanding Canada's surface climates and the processes responsible for their creation and control.
