Stanley Hillyard, a biologist and professor with the UNLV School of Dental Medicine, will speak at an upcoming Science Café Las Vegas. His talk is titled, "The Devils Hole Pupfish: A Canary in the Coal Mine of Global Climate Change."

The Devils Hole pupfish (Cyprinodon diabolis) lives in the opening of a warm aquifer (about 93° F) in Ash Meadows National Wildlife Refuge. The population of this pupfish species once exceeded 500 but declined to a low of 35 as recently as 2013. It is now at about 144 adult fish. Hillyard has been counting fish in Devils Hole for 40 years and seen these large fluctuations in population size. He will discuss possible reasons for the decline and lack of recovery in terms of climate change and temperature effects on reproduction.
