View Resource Testing Hypotheses on Plant-herbivore Interactions Using Sawfly Galls on Willows

In this experiment, students observe sawfly galls (Hymenoptera) on willow (Salix) trees to investigate some of the ecological consequences of plant-herbivore relationships. The physical and chemical traits of plants vary due to genes and environmental factors, such as soil moisture, nutrient levels, exposure to pathogens, and exposure to herbivores. These traits can lead to differences in...
