The boreal forest is the northern-most woodland biome, whose natural history is rooted in the influence of low temperature and high-latitude. Alaska's boreal forest is now warming as rapidly as the rest of Earth, providing an unprecedented look at how this cold-adapted, fire-prone forest adjusts to change. This volume synthesizes current understanding of the ecology of Alaska's boreal forests and describes their unique features in the context of circumpolar and global patterns. It tells how fire and climate contributed to the biome's current dynamics. As climate warms and permafrost (permanently frozen ground) thaws, the boreal forest may be on the cusp of a major change in state. The editors have gathered a remarkable set of contributors to discuss this swift environmental and biotic transformation. Their chapters cover the properties of the forest, the changes it is undergoing, and the challenges these alterations present to boreal forest managers. In the first section, the reader can absorb the geographic and historical context for understanding the boreal forest. The book then delves into the dynamics of plant and animal communities inhabiting this forest, and the biogeochemical processes that link these organisms. In the last section the authors explore landscape phenomena that operate at larger temporal and spatial scales and integrates the processes described in earlier sections. Much of the research on which this book is based results from the Bonanza Creek Long-Term Ecological Research Program. Here is a synthesis of the substantial literature on Alaska's boreal forest that should be accessible to professional ecologists, students, and the interested public.

p.9 Resources are the energy and materials in the environment that are used by organisms to support their growth and maintenance.
 
p.9 Landscape-scale disturbances... are critical determinants of the natural structure and process rates in ecosystems (Pickett and White 1985, Sousa 1985)... An important challenge for the future is to manage interactive controls in such a way that the most valuable attributes of the boreal forest, both economically and aesthetically, are sustained in the future
 
p.58 Developing a greater understanding of the dynamic relationship among climatic and ecosystem processes increases our ability to predict ecosystem responses to a changing climate, predict changes in the disturbance regime, and anticipate biological responses to changes in the physical regime.
 
p.86 The diversity of boreal forests is a dynamic property that responds sensitively to disturbance.
 
p.180 We suggest that the interactions between soil chemistry and plant production are the primary dynamics that limit intraseason forest growth.
 
p.224 The ecological interactions set into motion by trophic [JLJ - Relating to the feeding habits of different organisms in a food chain or web] exchanges discussed in this chapter demonstrate the potential array of both clear, direct effects and more subtle indirect effects that cascade through the ecosystem. Putting together the picture of interactions across microbial, plant, and megafaunal levels is akin to piecing together a jigsaw puzzle, except there is no guarantee that the pieces have fixed shapes or are of a definite number.
