Norms of reaction for size at metamorphosis (SM) and length of larval period (LP) were compared among treefrog species raised at different food levels (Hyla cinerea vs H. gratiosa) and at different temperatures (H. cinerea vs H. gratiosa vs H. squirella). Hyla cinerea and Hyla gratiosa show parallel norms of reaction across food levels and temperatures. Across temperatures, H. squirella shows a much smaller change in SM relative to change in LP than do H. cinerea and H. gratiosa. This difference in shape of reaction norms may reflect different histories of selection resulting from these species' use of different larval habitats.
