Shaffer and Rank will use a willow leaf beetle (Chrysomela                 aenicollis) to study the effects of local environment conditions                on the costs and benefits of animal social behavior.  These                     beetles feed on high elevation willows in the Sierra Nevada                     mountains of Eastern California.  The larvae use a chemical,                    salicin, from the willows to protect themselves from potential                  predators.  Additionally, these beetles cluster their eggs and                  feed in groups as larvae, which probably makes the chemical                     defense more effective.  They will study how the costs and                      benefits of larval social behavior depend on the leaf chemistry                 of their host plants.  To do this, they will conduct experiments                in nature measuring larval and egg survivorship among groups of                 different sizes on willows with different amounts of salicin in                 the leaves.  They will also use a biochemical technique, gel                    electrophoresis, to study the evolutionary relationships between                beetle populations in several mountain canyons.  Their results                  should contribute substantially to the field of plant-herbivore                 interaction.
