Direct link established between tropical tree and insect diversity

Higher tree species diversity leads directly to higher diversity of leaf-eating insects, researchers report in the July 13, 2006 early-online version of the journal Science.

Understanding the drivers of the high diversity in tropical forests has been a major question since Darwin and Wallace visited tropical forestsand even before, Smithsonian co-author Scott Miller writes, We found that higher tropical tree diversity explains why there are more leaf-eating insects in tropical than in temperate forests.

It may be obvious that forests with greater numbers of tree species should support a wider variety of leaf-eating insects than do less diverse forests, but no one had ever done the experiment to rule out the major alternative explanation: that insect species in the tropics eat the leaves of a smaller number of host trees (are more host specific), which would also result in more insect species in a given area. This study presents the best experimental evidence to date to account for the latitudinal gradient in herbivorous insect biodiversity.

The international effort involved a comparison of insectsTM eating habits in temperate sites in Central Europe and lowland tropical sites near Mandang, Papau New Guinea (PNG). The team of insect ecologists, taxonomists and field assistants led by Vojtech Novotny, from the University of South Bohemia, Czech Republic, includes co-authors from the SmithsonianTMs National Museum of Natural History (NMNH), National Zoological Park (NZP) and Tropical Research Institute (STRI) and the University of Minnesota in the U.S. and Comenius University in Slovakia.

The team compared 850 species of leaf-eating insects from 14 tree species in temperate floodplain forest sites in Moravia and from 14 tree species in lowland tropical sites in Papua New Guinea (PNG). They also compared caterpillars from 8 trees in Slovakia, and 8 trees in PNG. Tree species were chosen such tha
