The unpopular vine kudzu has exploded. Smithsonian Tropical Research Institute researchers in Panama and professors at the University of Wisconsin-Milwaukee think the fundamental structural change in the physical make-up of forests are drastically changing and will have a profound impact on humanity in years to come. Their research suggests these changes will affect animals, human communities and businesses that rely on forests for their livelihood. Professor Oliver Phillips, of the University of Leeds, published a controversial study in 2002 claiming vines were not only becoming more common in the Amazon but also in America. Scientists cannot identify the reason for the increasing vine growth and will be initiating a network of large-scale, long-term monitoring plots to study forest dynamics.
