  abstract = {{B}iological invasions offer interesting situations for observing how novel interactions between closely related, formerly allopatric species may trigger phenotypic evolution in situ. {A}ssuming that successful invaders are usually filtered to be competitively dominant, invasive and native species may follow different trajectories. {N}atives may evolve traits that minimize the negative impact of competition, while trait shifts in invasives should mostly reflect expansion dynamics, through selection for colonization ability and transiently enhanced mutation load at the colonization front. {T}hese ideas were tested through a large-scale common-garden experiment measuring life-history traits in two closely related snail species, one invasive and one native, co-occurring in a network of freshwater ponds in {G}uadeloupe. {W}e looked for evidence of recent evolution by comparing uninvaded or recently invaded sites with long-invaded ones. {T}he native species adopted a life history favoring rapid population growth (i.e., increased fecundity, earlier reproduction, and increased juvenile survival) that may increase its prospects of coexistence with the more competitive invader. {W}e discuss why these effects are more likely to result from genetic change than from maternal effects. {T}he invader exhibited slightly decreased overall performances in recently colonized sites, consistent with a moderate expansion load resulting from local founder effects. {O}ur study highlights a rare example of rapid life-history evolution following invasion.},
