Persistence of cold-water biodiversity

Researchers report that although the loss of glaciers worldwide endangers the biodiversity of mountain ecosystems through the loss of specialized melt-water communities, biological and glacier retreat data from Glacier National Park from 1850 through 2015 suggest that a specialized cold-water invertebrate community has persisted through time, even in areas that were deglaciated more than 150 years ago; the results suggest that high-altitude streams and snow-fed water sources may serve as refuges for mountain biodiversity, according to the authors.
