table decline rates cited above and the 16 m depth to modern water
table -- this species would have been isolated for 180,000 to
possibly as much as 800,000 years. That isolation times in excess
of 100,000 years are credible is supported by the absence, at
Devils Hole, of geologic evidence for late Pleistocene ground-
water discharge, as well as by the dated paleo-water levels in
Brown's Room.
Introduction of C. diabolis into Devils Hole
44,000 years, by mechanisms that are independent
water-table decline, is also possible, and should
completely discounted; three such mechanisms are
within the past
of regional
not be
discussed.
