image: Single specimen from the Smithsonian's National Parasite Collection at the National Museum of Natural History. The research team drew on this collection to analyze the impact of climate change on parasites. It is an acanthocephalan, Macracanthorhynchus hirudinaceus, usually found in pigs. The National Parasite Collection holds millions of parasite specimens in connection with information about their geographic distribution. This material relates to a paper that appeared in the 06 September 2017, issue of Science Advances, published by AAAS. The paper, by C.J. Carlson at University of California, Berkeley in Berkeley, Calif., and colleagues was titled, "Parasite biodiversity faces extinction and redistribution in a changing climate." view more
