In a new study in the Journal of Biogeography an international team of researchers led by Harvard University assembled one of the largest global assessment of fern diversity. The study integrated digitized herbarium data, genetic data, and climatic data and discovered 58% of fern species occur in eight principally montane hotspots that comprise only 7% of Earth's land area. And within these hotspots, patterns of heightened diversity were amplified at higher elevations above 1000 meters.
