*NEW*	Pyatt,F.B. & Storey,D.M., 1999. Toxicity testing using Daphnia magna Straus in student assessments of water pollution. J.Biol.Educ., 33 (3), 164-170. This report gives a simple procedure, allows groups of students to investigate the toxic effects of potential environmental pollutants in the laboratory, using Daphnia magna as a test organism. The procedure introduces students to dose-dependant toxicity.

*NEW*	Trevors,J.T., 1998. Cellulose decomposition in soil. J.Biol.Educ., 32 (2), 133-136. This article describes a laboratory technique for studying decomposition of organic matter such as cellulose paper, cotton cloth (calico) and straw in soil.
