title: Data from: Loss and recovery of ecological diversity associated with evolutionary rescue in abruptly and gradually deteriorating environments

description: Populations may survive environmental deterioration by evolutionary
 adaptation.  However, such evolutionary rescue events may be
 associated with ecological costs, such as reduction in growth performance
 and loss of ecologically important genetic diversity.  Those
 negative ecological consequences may be mitigated by additional adaptive
 evolution.  Both the ecological costs and the opportunities for
 additional evolution are contingent on the severity of environmental
 deterioration.  Here we hypothesize that populations
 evolutionarily rescued from faster, relative to slow, environmental
 deterioration suffer more severe long-term fitness decline and diversity
 loss.  An experiment with the model adaptive radiation of
 bacterium Pseudomonas fluorescens exposed to abruptly or gradually
 increased antibiotic stress supported our hypothesis.  The effect
 of additional adaptive evolution in recovering population size and
 ecological diversity was far from perfect.  Cautions are
 therefore needed in predicting the role of rapid evolution for mitigating
 the impacts of environmental changes, in particular very fast
 environmental deterioration.  We also found that bacterial
 populations rescued from gradually increased antibiotic stress evolved
 higher levels of antibiotic resistance, lending more support to aggressive
 chemotherapy in pathogen control.
