| 摘要： | Smokes, obscurants, and riot-control agents constitute a diverse group of chemical compounds that are released into the environment during military training exercises. Concern has been expressed over the use of these compounds and how they may affect threatened and endangered (T&E) species that reside on military installations. This report discusses strategies for developing a statistically sound approach to assessing effects of military smokes, obscurants, and riot-control agents on plant and animal species, including T&E species, and their ecosystems. It provides a general overview of sampling designs and statistical analysis procedures and lays a basic foundation for understanding: (1) principles of experimental design and statistical analysis procedures; (2) strengths and weaknesses of each design and analytical procedure; and (3) ecological and statistical rationale for selection of particular designs. Volume 1 of this report series will he an overview of methods examined in the series, their application, and applicable regulations. Volume 2 (CERL TR 97/140, September 1997) reviews methods for assessing ecological risks. Volume 4 (CERL TR 99/56, July 1999) discusses chemical analytical methods. |
