As Jay explained to me in an email, “After seeing that mouse video, it didn’t take long to decide that I needed to get down there. The world’s second highest active volcano, Llullaillaco straddles the Argentina-Chile border and towers above the Atacoma Desert, which lies between it and the Pacific Ocean. He also knew that the highest mammal vouchered by a museum specimen was a Large-eared Pika ( Ochotona macrotis, a rabbit relative), from 5,182 m (17,001 ft) in the Himalayas, and that a 1921 Everest expedition reported credible sightings of that same species at 6,130 m (20,112 ft). He had long been fascinated by mountaineer sightings of high-altitude animals, such as geese flying overhead near the summit of Mount Everest (8,849 m, 29,032 ft). In 2019, while on sabbatical leave in Argentina, Jay was contacted by two climbers who had video of a mouse scurrying across snow at 6,205 m (20,358 ft) on Volcán Llullaillaco. Jay’s many publications include a new book on hemoglobin, the molecule in blood that carries oxygen to our tissues he’s also an experienced backpacker, as I learned years ago when we hiked for several days together in the Grand Canyon. Jay Storz is a distinguished University of Nebraska professor, an expert on adaptations to extreme environments, and a biologist as at home in the field as in the laboratory.

23 for a pdf of the article, write to Now natural history is once again flourishing, exemplified by American Naturalist, Ecology, Proceedings of the National Academy of Sciences, and other high impact journals featuring primarily descriptive studies among their more theory-oriented contributions. Biologists seek to understand organisms, their diversification and environmental relationships-not theories and experiments per se-and discoveries of new organisms and new facts about organisms reset the research cycles of hypothesis testing that underlie conceptually progressive science” ( Trends in Ecology and Evolution 20, p. Nevertheless, organisms themselves embody genetics, development, morphology, physiology and behavior they are the units of populations, communities and ecosystems. Back in 2005, concerned about dwindling support for natural history, I noted that “Theories summarize science, tell us what to measure when we test hypotheses, and help us study nature better. This posting highlights a spectacular discovery, recently reported in one of the world’s most prestigious periodicals.
