title: Data from: Rapid evolution of dispersal ability makes biological invasions faster and more variable

description: Genetic variation in dispersal ability may result in the spatial sorting
 of alleles during range expansion. Recent theory suggests that spatial
 sorting can favour the rapid evolution of life history traits at expanding
 fronts, and therefore modify the ecological dynamics of range expansion.
 Here we test this prediction by disrupting spatial sorting in replicated
 invasions of the bean beetle Callosobruchus maculatus across homogeneous
 experimental landscapes. We show that spatial sorting promotes rapid
 evolution of dispersal distance, which increases the speed and variability
 of replicated invasions: after 10 generations of range expansion,
 invasions subject to spatial sorting spread 8.9% farther and exhibit
 41-fold more variable spread dynamics relative to invasions in which
 spatial sorting is suppressed. Correspondingly, descendants from spatially
 evolving invasions exhibit greater mean and variance in dispersal
 distance. Our results reveal an important role for rapid evolution during
 invasion, even in the absence of environmental filters, and argue for
 evolutionarily informed forecasts of invasive spread by exotic species or
 climate change migration by native species.
description: Invasion experiment
 dataData collected from
 experimental laboratory invasions of the bean beetle Callosobruchus
 maculatus. Data show the post-dispersal densities of beetles in each patch
 of the one-dimensional invasion array. Columns (in order) are date, start
 time, end time, population ID, generation (1-10), treatment (0 = spatially
 sorted, 1 = shuffled), array_patch (the patch number in the dispersal
 array), array_shift (the cumulative number of patches that the invasion
 has been shifted towards 0 each generation to ensure that the invasion
 would fit in the spatial extent of the array), invasion_patch (array_patch
 + array_shift), N_females (number of females in each patch), N_males
 (number of males in each patch), N_unsexed (number of unsexed beetles in
 each patch), and notes.invasion_experiment.csvCommon garden dispersal dataData collected from a common garden experiment following experimental laboratory invasions of the bean beetle Callosobruchus maculatus. Data show the dispersal distance of beetles from each replicate population of the invasion experiment. Columns (in order) are date, start time, end time, population ID, common garden generation (1-2), treatment (0 = spatially sorted, 1 = shuffled), replicate (1-3; within-population replicate dispersal trials), sex (0 = female, 1 = male), distance (number of patches dispersed), and notes.common_garden_dispersal.csvCommon garden fecundity dataData collected from a common garden experiment following experimental laboratory invasions of the bean beetle Callosobruchus maculatus. Data show the lifetime reproductive success of females from each replicate population of the invasion experiment. Columns (in order) are date that offspring were counted, population ID, common garden generation (1-2), female ID (1-11 for each population), treatment (0 = spatially sorted, 1 = shuffled), and number of offspring produced by each female.common_garden_fecundity.csvDispersal heritability dataData collected from half-sib breeding design to investigate the additive genetic variance of dispersal distance in the bean beetle Callosobruchus maculatus. Data show the dispersal distance of beetles from each full-sib family. Columns (in order) are date, experiment start time, sire ID, dam ID, offspring ID, replicate (varies for each dam-sire combination depending on the number of offspring the pair produced), sex (0 = female, 1 = male), and distance (number of patches dispersed).dispersal_heritability.csv
