Ecosystem effects from air pollution in the Adirondacks, Catskills, and elsewhere in New York have been substantial. Efforts to characterize and quantify these impacts, and to examine more recent recovery, have focused largely on surface waters, soils, and forests. Lakes, streams, and soils have acidified. Estuaries have become more eutrophic. Nutrient cycles have been disrupted. Mercury has bioaccumulated to toxic levels. Plant species composition has changed. Some surface waters show signs of partial chemical recovery in response to emissions control programs, but available data suggest that soil chemistry may continue to deteriorate under expected future emissions and deposition. Resource managers, policymakers, and scientists now need to know the extent to which current and projected future emissions reductions will lead to ecosystem recovery.In this book, Timothy J. Sullivan provides a comprehensive synthesis of past, current, and potential future conditions regarding atmospheric sulfur, nitrogen oxides, ammonium, and mercury deposition; surface water chemistry; soil chemistry; forests; and aquatic biota in New York, providing much needed information to help set emissions reduction goals, evaluate incremental improvements, conduct cost/benefit analyses, and prioritize research needs. He draws upon a wealth of research conducted over the past thirty years that has categorized, quantified, and advanced understanding of ecosystem processes related to atmospheric deposition of strong acids, nutrients, and mercury and associated ecosystem effects. An important component of this volume is the new interest in the management and mitigation of ecosystem damage from air pollution stress, which builds on the "critical loads" approach pioneered in Europe and now gaining interest in the United States.This book will inform scientists, resource managers, and policy analysts regarding the state of scientific knowledge on these complex topics and their policy relevance and will help to guide public policy assessment work in New York, the Northeast, and nationally.

Описание: What does it mean to narrate the self? Is there a 'self' to be narrated? What form should such narratives or writings take? The authors of the sixteen essays collected in this volume use a variety of approaches to study a broad range of what are now called 'ego-documents' from the Renaissance to the beginning of the nineteenth century. From them it emerges that 'the self' is not an acknowledged fact, but rather a historical process, which is neither linear nor stable. Que peut bien signifier l' criture de soi l' poque moderne ? Y a-t-il m me un moi d crire et raconter ? Quelles formes peuvent prendre de tels r cits ? Les seize contributions rassembl es dans ce volume cherchent r pondre ces questions en interrogeant, suivant diverses approches, une grande vari t de textes de la Renaissance la R volution, relevant de ce que l'historiographie tend nommer des ego-documents . A travers l' tude de ces textes, il appara t que le moi , loin d' tre un donn universel, est le fruit d'un processus historique qui n'est ni lin aire ni stable.
