From the front garden to the continent: Why biodiversity does not increase evenly from small to large

The number of species does not increase evenly when going from local ecosystems to continental scales -- a phenomenon ecologists have recognized for decades. Now, an international team of scientists has developed a new theory to explain the three distinct phases typical of species distributions across scales. The theory may be crucial for estimating how many species are lost when habitats are destroyed.
