The overall goal of the research program is to determine how plant/herbivore interactions change with increasing atmospheric CO/sub 2/ concentration and how these changes affect community structure and functioning. Five specific objectives have been developed to approach these goals over the grant period. These objectives are to determine: (1) if specialist feeding herbivores respond to host plant CO/sub 2/ enrichment in the same manner as generalist feeders, (2) if the impact of defoliation is lessened under enriched CO/sub 2/conditions, (3) the biochemical basis for the altered nutritional value of leaves resulting from elevated CO/sub 2/, (4) the demographic and consumption responses of an herbivore to CO/sub 2/ regimes, and (5) whether plants with the C/sub 4/ photosynthetic pathway will also have altered relationships with herbivores. Significant progress has been made on three of these goals. Manuscripts are appended. A revised study plan to complete the remaining objectives is appended.
