The Introduction to Sustainability course at the University of Iowa seeks to educate the aware, informed and action-oriented sustainable citizen. A phenomenographic analysis and retrospective pretest were utilized to determine how students formed conceptions of sustainability as a result of completing the course. The study indicated that student conceptions of sustainability can be characterized by the “aware, informed and action-oriented” spectrum. LINK TO FULL ARTICLE.
In tanks at the University of Iowa, mussels equipped with heart rate monitors are purifying water with their excrement. Like human heart monitors, the gadgets glued to the mussels’ shells provide information about activity and metabolism. But in the mussels’ case, this information is helping researchers understand how mussels cleanse the water of agricultural runoff. Link to full article.
Native freshwater mussels can influence the aquatic N cycle, but the mechanisms and magnitude of this effect are not fully understood. We assessed the effects of Amblema plicata and Lampsilis cardium on N transformations over 72 d in 4 continuous-flow mesocosms, with 2 replicates of 2 treatments (mesocosms with and without mussels), equipped with electronic water-chemistry sensors. We compared sensor data to discrete sample data to assess the effect of additional sensor measurements on the ability to detect mussel-related effects on NO3– formation. Link to full article.
