Book Description
Whether in felling trees for wood, rearing insects for biological control, or culling animals for conservation purposes, efficient management of biological systems requires quantitative analysis of population growth and harvesting policies. Aiming to encourage the exchange of ideas among scientists involved in the management of fisheries, wildlife, forest stands, and pest control, the authors of this work present a general framework for modeling populations that reproduce seasonally and that have age or stage structure as an essential component of management strategy. The book represents the first time that examples from such diverse areas of biological resource management have been brought together in a unified modeling framework using the standard notation of mathematical systems theory. In addition, the authors combine a nonlinear extension of Leslie matrix theory and certain linear elements, thereby permitting interesting analytical results and the creation of compact, realistic simulation models of resource systems.

Book Description
In recent decades, community forestry has taken root across Canada. Locally run initiatives are lauded as welcome alternatives to large corporate and industrial logging practices, yet little research has been done to document their tangible outcomes or draw connections between their ideals of local control, community benefit, ecological stewardship, and economic diversification and the realities of community forestry practice. This book brings together the work of over twenty-five researchers to provide the first comparative and empirically rich portrait of community forestry policy and practice in Canada. Tackling all of the forestry regions from Newfoundland to British Columbia, it unearths the history of community forestry, revealing surprising regional differences linked to patterns of policy-making and cultural traditions. Case studies celebrate innovative practices in governance and ecological management while uncovering challenges related to government support and market access. The future of the sector is also considered, including the role of institutional reform, multiscale networks, and adaptive management strategies.

Book Description
The current synthesis is a review of research examining the effects of large-scale mountain pine beetle (MPB)-related disturbance conducted predominantly over the past five years. The emphasis is on research that explicitly examines the impact of beetle kill (or biotic disturbance in general) and the cumulative effects of large scale salvage harvesting operations in response to beetle kill. In general, forest disturbance has been found to increase snow accumulation and melt, reduce interception loss and evaporation, and increase runoff and stream flow.--Document.

Book Description
Written for plant breeders, researchers and post-graduate students, this excellent new book provides a comprehensive review of the methods and underlying theoretical foundations used for selection in plant breeding programs. The authors review basic elements of population and quantitative genetic theory, moving on to consider in a unique way the tackling of the problems presented by soil heterogeneity and intergenotypic competition when selecting quantitative characters.

Book Description
Big-Leaf Mahogany is the most important commercial timber species of the tropics. Current debate concerning whether to protect it as an endangered species has been hampered by the lack of complete, definitive scientific documentation. This book reports on vital research on the ecology of big-leaf mahogany, including genetic variations, regeneration, natural distribution patterns and the silvicutural and trade implications for the tree.
