Why are there so many species of herbivorous insects in tropical rainforests?
Original language description
While recent progress has been made in understanding mechanisms of tree species coexistence in tropical forests, a simple explanation for the even more extensive diversity of insects feeding on these plants has been missing. We compared folivorous insects from temperate and tropical trees to test the hypothesis that herbivore species coexistence in more diverse communities could reflect narrow host specificity relative to less diverse communities. Temperate and tropical tree species of comparable phylogenetic distribution supported similar numbers of folivorous insect species. Host specificity did not differ significantly between community samples, an indication that food resources are not more finely partitioned among folivorous insects in the tropicsthan in temperate forests. These findings suggest that the latitudinal gradient in insect species richness could be a direct function of plant diversity, which increased sevenfold from our temperate to tropical study sites.

Proč je v tropických lesích tolik druhů herbivorního hmyzu?
Czech description
Hostitelská specializace a druhová rozmanitost herbivorního hmyzu se neliší mezi lesy tropického a mírného pásma, takže nárůst druhové diverzity herbivorního hmyzu směrem do tropů je způsoben zejména nárůstem druhové diverzity rostlin.
