Program for Ecosystem Research

Publications

The main products (or deliverables) of the program are scientific journal articles, books, and book chapters that describe the program's research results.

Program publications are below divided into (a) Books and (b) Refereed Journal Articles and Book Chapters. Other publication types (e.g., reports, conference proceedings and workshop reports, letters, and abstracts) are not included below.
 

Books

The book North American Temperate Deciduous Forest Responses to Changing Precipitation Regimes (Hanson and Wullschleger, 2003) is a comprehensive analysis of the first eight years of the program's Throughfall Displacement Experiment (TDE) at the Oak Ridge National Laboratory in Tennessee. Fifteen of the chapters in Karnosky et al. (2001) and (2003) document results from the program-sponsored Rhinelander, Wisconsin, FACE [free-air CO2 enrichment] experiment. The Pritchard and Amthor (2005) monograph is a synthesis of known effects of climatic change on major crops; its preparation was supported in part by the program. The Pace and Groffman (1998), Galloway et al. (2002), and Canham et al. (2003) books resulted from conferences that were supported in part by the program.
