  abstract = {{A}n understanding of the role of factors intrinsic to a species' life history in structuring contemporary genetic variation is a fundamental, but understudied, aspect of evolutionary biology. {H}ere, we assessed the influence of the propensity to outbreak in shaping worldwide genetic variation in {L}ocusta migratoria, a cosmopolitan pest well known for its expression of density-dependent phase polyphenism. {W}e scored 14 microsatellites in nine subspecies from 25 populations distributed over most of the species' range in regions that vary in the historical frequency and extent of their outbreaks. {W}e rejected the hypothesis that {L}. migratoria consists of two genetically distinct clusters adapted to habitats either rarely (nonoutbreaking) or cyclically (outbreaking) favourable to increases in population density. {W}e also invalidated the current subspecific taxonomic classification based on morphometrics. {B}ayesian inferences indicated evidence of a homogenizing effect of outbreaks on {L}. migratoria population structure. {G}eographical and ecological barriers to gene flow in conjunction with historical events can also explain the observed patterns. {B}y systematically assessing the effects of null alleles using computer simulations, we also provide a template for the analysis of microsatellite data sets characterized by a high prevalence of null alleles.},
