Silviculture, as an integrative discipline, must combine management skills with scientific and technical knowledge in the management of forests and woodlands. While traditionally, silviculturists worked in fine resolution landscapes, today's practitioner must look at encompassing both larger geographic areas (adjacent stands, watersheds, regions, subregions) and wider objectives (trees as well as wildlife, commodities, recreation, sustainability, biological diversity, air quality, and ecosystem resilience). The 12 papers in this proceedings explore the past, present, and desired future of silviculture's role and practice. Examination of disturbance ecology in ecosystem management includes natural and induced disturbances, and management options. Discussion of desired future conditions includes the importance of understanding the connection between ecological values and social values, as well as historic reference conditions as they relate to creating forest plans. A section on inventory, monitoring, and adaptive management looks at multiresource and multiscale data assessments and temporal continuity; included are design alternatives and a discussion of how to adapt silvicultural prescriptions. Case studies throughout the proceedings help the reader understand the practical applications, the successes, and the need for further work.
Many exciting discoveries in recent decades have contributed new knowledge to our understanding of the mechanisms that regulate various stages of plant growth and development. Such information, coupled with advances in cell and molecular biology, is fundamental to crop improvement using biotechnological approaches. Two volumes constitute the present work. The ?rst, comprising 22 chapters, commences with introductions relating to gene regulatory models for plant dev- opment and crop improvement, particularly the use of Arabidopsis as a model plant. These chapters are followed by speci?c topics that focus on different developmental aspects associated with vegetative and reproductive phases of the life cycle of a plant. Six chapters discuss vegetative growth and development. Their contents consider topics such as shoot branching, bud dormancy and growth, the devel- ment of roots, nodules and tubers, and senescence. The reproductive phase of plant development is in 14 chapters that present topics such as ?oral organ init- tion and the regulation of ?owering, the development of male and female gametes, pollen germination and tube growth, fertilization, fruit development and ripening, seed development, dormancy, germination, and apomixis. Male sterility and self-incompatibility are also discussed.
