Rare fish species in steep decline as global, regional temperatures soar
FRISCO — Rare fish living in desert freshwater springs in Nevada may be adapted to warm weather, but they may not be able to survive long-term global warming, researchers said this week, outlining the threats facing endangered Devils Hole pupfish.
At times, the population of the fish has been as low as just 35 individuals, and the geothermal water on a small shelf near the surface of an isolated cavern in the Nevada desert where the pupfish live is heating up as a result of climate change and is likely to continue heating to dangerous levels.
From the 1970s through the mid-1990s, the population appeared stable, but 1997 marked the start of a long-term decline that is probably linked with global warming, according to scientists who closely watch the fish. The population dropped to an all-time low of just 65 fish in the fall of 2013, with a further decline expected this year that will push the species toward extinction. Continue reading
