Forest Ecosystem Management. A management approach that aims to maintain healthy and resilient forest ecosystems by focusing on a reduction of differences between natural and managed landscapes to ensure long-term maintenance of ecosystem functions and thereby retain the social and economic benefits they provide to society.That is the definition of forest ecosystem management proposed in this book, which provides a summary of key ecological concepts supporting this approach. The book includes a review of major disturbance regimes that shape the natural dynamics of the boreal forest and gives examples from different Canadian boreal regions. Several projects implementing the forest ecosystem management approach are presented to illustrate the challenges created by current forestry practices and the solutions that this new approach can provide. In short, knowledge and understanding of forest dynamics can serve as a guide for forest management. Planning interventions based on natural dynamics can facilitate reconciliation between forest harvesting needs and the interests of other forest users.

Forest pest conditions in Alberta, Saskatchewan, Manitoba, and the Northwest Territories during 1990 are summarized and some predictions of infestation status are given for 1991. Twelve major pests are discussed, and additional noteworthy insects, diseases, and tree damage agents are reported in a table. An updating of surveys for acid rain symptoms in permanently established ARNEWS (Acid Rain National Early Warning System) plots and pest damage incidence in young coniferous stands are also reported.

Synthesizing some 150 years of research, this is the only book to cover the biology and behavioral ecology of tent caterpillars. Terence D. Fitzgerald discusses the systematics, distribution, and host range of North American and Eurasian species of tent caterpillars. He then considers the anatomy and physiology of the egg, larva, pupa, and adult, with particular emphasis on sensory physiology, silk production, reproductive behavior, overwintering adaptations, and the energetics of adult and larva locomotion.

This checklist of the Lepidoptera (butterflies and moths) of Alberta lists 2367 species reported to occur in the province, as well as 138 species whose occurrence in Alberta is probable. Each species entry includes adult flight time and distribution status in the Cordilleran, Boreal, and Grasslands ecozones, as well as references to taxonomic works and to the literature and public collection sources of the records. Detailed notes on taxonomy, nomenclature, distribution, habitat, and biology are given for 1524 of the listed species. An additional section provides details on 171 species erroneously reported from Alberta in previous works. The authors hope it will be a useful resource for anyone carrying out species-level work on Lepidoptera in western Canada, or taxonomic work on Lepidoptera in general. An introductory section provides a general overview of the order Lepidoptera and the natural regions of Alberta, and the history and current state of knowledge of Alberta Lepidoptera. Each of the 63 families (and selected subfamilies) occurring in Alberta is briefly reviewed, with information on distinguishing features, general appearance, and general biology. The list is accompanied by an appendix of proposed nomenclature changes, consisting of revised status for 25 taxa raised from synonymy to species level, and new synonymy for 20 species-level and one genus-level taxa here considered to be subjective synonyms, with resultant revised synonymy for one taxon and formalization of seven new combinations.

Based on a very successful one-semester course taught at Harvard, this text teaches students in the life sciences how to use differential equations to help their research. It needs only a semester's background in calculus. Ideas from linear algebra and partial differential equations that are most useful to the life sciences are introduced as needed, and in the context of life science applications, are drawn from real, published papers. It also teaches students how to recognize when differential equations can help focus research. A course taught with this book can replace the standard course in multivariable calculus that is more usually suited to engineers and physicists.
