A glimpse of the microbial world's hidden beauty

To collect, identify and document these single-celled algae called desmids, USGS biologist Barry H. Rosen has traveled by airboat into the interior of Florida’s Loxahatchee National Wildlife Refuge, where decaying marsh grasses created a mosaic of peat soils and the soft, slightly acidic water where desmids grow. Rosen thinks the area may have some of the world’s greatest
