title: Data from: Asymmetric competition impacts evolutionary rescue in a changing environment

description: Interspecific competition can strongly influence the evolutionary response
 of a species to a changing environment, impacting the chance that the
 species survives or goes extinct. Previous work has shown that when two
 species compete for a temporally shifting resource distribution, the
 species lagging behind the resource peak is the first to go extinct due to
 competitive exclusion. However, this work assumed symmetrically
 distributed resources and competition. Asymmetries can generate
 differences between species in population sizes, genetic variation and
 trait means. We show that asymmetric resource availability or competition
 can facilitate coexistence and even occasionally cause the leading species
 to go extinct first. Surprisingly, we also find cases where traits evolve
 in the opposite direction to the changing environment because of a ‘vacuum
 of competitive release’ created when the lagging species declines in
 number. Thus, the species exhibiting the slowest rate of trait evolution
 is not always the most likely to go extinct in a changing environment. Our
 results demonstrate that the extent to which species appear to be tracking
 environmental change and the extent to which they are preadapted to that
 change may not necessarily determine which species will be the winners and
 which will be the losers in a rapidly changing world.
