Smithsonian Scientists Show Differing Patterns of Rain Forest Biodiversity

One of the major issues in conservation and natural resource management is the distribution of species across landscapes. How widespread are species on average, and how much does the composition of a community of species change from place to place (known as "beta diversity")? Obviously, the pattern differs in different kinds of organisms and habitats, and beta diversity can be extreme across some environmental gradients.

An international group of entomologists and botanists, including Scott Miller and Karolyn Darrow from the National Museum of Natural History and Yves Basset from the Smithsonian Tropical Research Institute in Panama, with NMNH research associates Vojtech Novotny (Czech Academy of Sciences) and George Weiblen (University of Minnesota) and many others, has assembled a large data set representing 500 species of caterpillars, ambrosia beetles, and fruit flies across 75,000 square kilometers of contiguous lowland rain forest in Papua New Guinea. The study published in the 9 August 2007 issue of Nature shows that most lowland New Guinea insect and plant species are widely distributed. The results imply that where relatively uniform altitude, climate and soil support a low beta diversity of vegetation, the plant-feeding insect community also has low beta diversity.

The results have implications for the design of nature reserves as well as the control of forest pests. "There are some philosophical questions that our data should be useful to address," Miller said. "If you can preserve 10,000 hectares of forest, is it better to preserve it as 10 small 1,000 hectare plots or one large 10,000 hectare plot?"

Strategies for preserving high and low beta diversity forests might not be the same. "Our data from the New Guinea lowland forest suggests that bigger is better," he said. "In this kind of relatively uniform habitat, you're not losing a lot of beta diversity that would have to be represented by several smaller sites. But the opposite might apply on elevation or climate gradient."

There is still much to learn because collecting high intensity data is a very time-consuming process. "We haven't solved the conservation management question by any means," Miller said. He noted this kind of study needs to be replicated across a large spatial scale in the Amazon Basin and the Congo Basin to see if the low beta diversity pattern holds.
