Data from: Local adaptation is highest in populations with stable long-term growth

Theory suggests that the drivers of demographic variation and local
adaptation are shared and may feedback on one other. Despite some evidence
for these links in controlled settings, the relationship between local
adaptation and demography remains largely unexplored in natural
conditions. Using 10 years of demographic data and two reciprocal
transplant experiments, we tested predictions about the relationship
between the magnitude of local adaptation and demographic variation
(population growth rates and their elasticities to vital rates) across 10
populations of a well-studied annual plant. In both years, we found a
strong unimodal relationship between mean home-away local adaptation and
stochastic population growth rates. Other predicted links were either
weakly or not supported by our data. Our results suggest that declining
and rapidly growing populations exhibit reduced local adaptation,
potentially due to maladaptation and relaxed selection, respectively.
