Scientists re-examined 100 world-wide monitoring studies and were surprised to discover that, over decades, the number of species in many places has not changed much -- or has increased. But the researchers did discover that almost 80% of the communities showed changes in species composition. This shows that a rapid global turnover of species is happening, resulting in novel biological communities. The scientists conclude that biodiversity change may be as large a concern as biodiversity loss.
