COMMENT ON "Why Are There So Many Species of Herbivorous Insects in Tropical Rainforests?"
David A. Norton and Raphael K. Didham
Abstract: Novotny et al. (Reports, 25 August 2006, p. 1115) argued that higher herbivore diversity in tropical forests results from greater phylogenetic diversity of host plants, not from higher host specificity. However, if host specificity is related to host abundance, differences in relative host abundance between tropical and temperate regions may limit any general conclusion that herbivore diversity scales directly with host-plant diversity.

RESPONSE TO COMMENT ON "Why Are There So Many Species of Herbivorous Insects in Tropical Rainforests?
Vojtech Novotny, Pavel Drozd, Scott E. Miller, Miroslav Kulfan, Milan Janda, Yves Basset, George D. Weiblen
Abstract: Norton and Didham suggest that differences in plant abundance between tropical and temperate forests may influence the host specificity of herbivores in these forests. We agree in principle but show that this is likely only for very rare plant species in tropical forests. Studies of herbivores hosted by rare plant species would help our understanding of tropical plant-insect interactions.
