The American chestnut, whitebark pine, and several species of ash in the eastern United States are just a few of the North American tree species that have been functionally lost or are in jeopardy of being lost due to outbreaks of pathogens and insect pests. New pressures in this century are putting even more trees at risk. Expanded human mobility and global trade are providing pathways for the introduction of nonnative pests for which native tree species may lack resistance. At the same time, climate change is extending the geographic range of both native and nonnative pest species. Biotechnology has the potential to help mitigate threats to North American forests from insects and pathogens through the introduction of pest-resistant traits to forest trees. However, challenges remain: the genetic mechanisms that underlie trees' resistance to pests are poorly understood; the complexity of tree genomes makes incorporating genetic changes a slow and difficult task; and there is a lack of information on the effects of releasing new genotypes into the environment. Forest Health and Biotechnology examines the potential use of biotechnology for mitigating threats to forest tree health and identifies the ecological, economic, and social implications of deploying biotechnology in forests. This report also develops a research agenda to address knowledge gaps about the application of the technology.

"More Letters of Charles Darwin" is a compilation of letters written by Charles Darwin, the eminent naturalist and evolutionary biologist. This collection, along with other volumes of Darwin's letters, offers readers a firsthand look into his thoughts, scientific inquiries, and personal life. The letters cover a wide range of topics, including Darwin's observations during his travels, his research and experiments, and his interactions with fellow scientists and correspondents. They provide valuable insights into the development of Darwin's theories, including those presented in "On the Origin of Species." Reading Darwin's letters allows individuals to explore the intellectual and personal aspects of his life, gaining a deeper understanding of the challenges, controversies, and triumphs he faced during his scientific career. If you have an interest in the life and work of Charles Darwin, "More Letters of Charles Darwin" offers a rich collection of historical documents that contribute to our understanding of one of the most influential figures in the history of science.
