Collins %X Attempts to elucidate the factors controlling the structure of plant communities have relied increasingly on field experiments. This is a powerful approach for testing theoretical predictions that offers important advantages over observational and comparative studies. However, field experiments suffer from intrinsic difficulties as well as more-easily remediable limitations. Recent progress has been made by new approaches including the use of multifactor experiments, and the development and dissemination of better statistical tools. %B Trends in Ecology and Evolution %V 9 %P 94 -98 %G eng %M KNZ00442 %R 10.1016/0169-5347(94)90203-8
