Scientists estimate that fewer than 100 Devils Hole pupfish remain in their Mojave Desert home, but a conservation biologist at the University of California, Berkeley, is giving important guidance in the efforts to rescue them by establishing a captive breeding program.
Chris Martin has bred more than 3,000 hybrid fish in his time as a graduate student in evolution and ecology at UC Davis, a pursuit that has helped him create one of the most comprehensive snapshots of natural selection in the wild and demonstrated a key prediction in evolutionary biology.
Two groups of small fish, one from a Caribbean island and one from the Yucatan peninsula of Mexico, exhibit some of the fastest rates of evolution known in any organism.
For the first time, an earthquake was recorded live in Devils Hole, home to the only population of a critically endangered pupfish species.

By Randal C. Archibold No doubt, it is hard to be a fish in a desert. But, to the dismay and bafflement of scientists, the Devils Hole pupfish, a quick-darting iridescent blue minnow, are veering toward extinction.
It's 110 degrees, hardly a heat wave for Death Valley. And in a small, bathtub-warm pool below a steep, rocky incline, small fish appear to be at play, darting and chasing each other through patches of algae.
Scientists trying to study the endangered Devils Hole pupfish near Death Valley inadvertently nudged the endangered fish closer to extinction.
The Devil's Hole pupfish, Cyprinodon diabolis, is an endangered species of fish native to Devil's Hole, a geothermal (92Â°F), aquifer-fed pool within a limestone cavern in the Amargosa Desert of Nevada east of Death Valley. It is the smallest desert pupfish species, averaging .75 in (19 mm) in length. Physical Description Devil's Hole pupfish are less than .98 in (2.5 cm) long and resemble other pupfish in shape. They lack pelvic fins and have large heads and long anal fins. Breeding...
