An assortment of specimens from the Smithsonian's National Parasite Collection at the National Museum of Natural History. The National Parasite Collection holds more than 20 million parasite specimens in connection with information about their geographic distribution and host animals. A team of researchers drew on this collection to analyze the impact of climate change on parasite biodiversity in the 21st century. Their findings are published in the Sept. 6 issue of Science Advances.
