    This work is part of our ongoing experimental study of the interactions between ecology and evolution in natural environments.  We extended the range of guppies over barrier waterfalls that had excluded them from headwaters and have followed their population growth with monthly mark-recapture plus monitored their impacts on the only other resident fish species and the ecosystem.  We assayed life history evolution (male age and size at maturity) with common garden experiments executed every year for the first four years after the introduction.  We observed a lag in when male traits evolved that corresponds to the onset of density regulation.
