Isolation of Native Soil Microorganisms with Potential for Breaking Down Biodegradable Plastic Mulch Films Used in Agriculture Graham Bailes1, Margaret Lind1, Andrew Ely1, Marianne Powell2, Jennifer Moore-Kucera3, Carol Miles2, Debra Inglis2, Marion Brodhagen1 1Biology Department, Western Washington University, 2Washington State University Northwestern Research and Extension Center, 3Department of Plant and Soil Science, Texas Tech University Plastic films labeled "biodegradable" are commercially available for agricultural use as mulches. Tillage represents an attractive disposal method, but degradation under field conditions is poorly understood. The purpose of this study was to develop methods for isolating native soil fungi and bacteria that colonize plastic mulch films after field burial.
A General Method for Evaluating Incubation of Sucrose Craving in Rats Jeffrey W. Grimm1, Jesse Barnes1, Kindsey North1, Stefan Collins1, Rachel Weber1 1Department of Psychology and Program in Behavioral Neuroscience, Western Washington University Responding for food or drug-paired cues increases over the course of a period of abstinence and this may relate to an increased susceptibility to relapse behaviors. Here we detail a procedure for evaluating this "incubation of craving" in rats that have self-administered sucrose.
