"A team of researchers led by William F. Laurance of the Smithsonian Tropical Research Institute reviewed more than 340 articles and papers generated by the Biological Dynamics of Forest Fragments Project (BDFFP), the world's largest and longest-running study of habitat fragmentation, since its inception in 1979.
They found that the effect of habitat fragmentation on the structure, composition and function of rainforests is far-reaching and widely felt. It increases local extinction rates for many plant and animal species; drastically alters species richness and abundance; and disrupts ecological processes, as well as creating opportunities for non-native species invasions, altering forest carbon storage and increasing vulnerability to fire.
"A surprising number of wildlife species are extremely sensitive to very small clearings," said Laurance. "Even a 30-meter-wide road alters the community composition of understory birds and other wildlife, and creates a complete barrier to the movements of some species."" more [Science Daily]
Of course, its not just rainforest ecosystems that suffer from habitat fragmentation, especially when they are on the order of 30-meter roads. Any ecosystem suffers with those kinds of impacts. At least this sort of thing is finally being documented.

Beryl Pfizer. "I write down everything I want to remember. That way, instead of spending a lot of time trying to remember what it is I wrote down, I spend the time looking for the paper I wrote it down on." [Quotes of the Day]
Now, we grab it from our aggregator and drop it in our blog. Then we make google find it. I think that's an improvement.
