Biologists have discovered three new species of groundwater salamander in Central Texas, including one living west of Austin that they say is critically endangered. They also determined that an already known salamander species near Georgetown is much more endangered than previously thought. They warn that more severe droughts caused by climate change and increasing water use in Central Texas have left groundwater salamanders 'highly vulnerable to extinction.'
