Use of mesocosm data to predict effects in aquatic ecosystems: Limits to interpretation: Chapter 16
Aquatic mesocosm studies are being used to refute a presumption of risk derived from laboratory toxicity tests conducted under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). Mesocosm studies incorporate many biological, chemical and physical characteristics of natural ecosystems. Hence, they serve as realistic surrogates of natural ecosystems and allow tests of pesticide effect a

Regional evaluations of acid deposition effects on forests: Eastern spruce-fir
Having reviewed the results of the Integrated Forest Study (IFS) project, we now try to place the results in a larger perspective by very briefly summarizing acid deposition effects and their potential role in forest health in the several forest types represented in the IFS project. This chapter gives brief overviews of the situation in eastern spruce-fir, eastern hardwood, and southern pine fores

Gravity modelling across the Transantarctic Mountains, Northern Victoria Land
During GANOVEX V and GANOVEX VI, new gravity data were collected in northern Victoria Land. The GANOVEX V data cover the Mt. Melbourne 1:250.000 quadrangle, while the GANOVEX VI data Transantarctic Mountains south of the Drygalski Ice Tongue. The two data sets are connected by a coastal traverse. The measurements were constrained by satellite-positioned elevation (GPS) data and, in some cases, ice
