  abstract = {{I}nvasive species often defy theoretical expectations, successfully establishing and spreading despite reduced propagule pressure and limited genetic diversity. {W}hat genomic mechanisms underpin this paradox? {H}ow do adaptive processes and host-pathogen interactions shape invasion outcomes? {A}nd which genes drive resistance and modulate pathogen virulence? {H}ere, we address these questions using a model of co-invasion: the {A}sian topmouth gudgeon ({P}seudorasbora parva) and its fungal parasite the {R}osette agent ({S}phaerothecum destruens), a system with profound ecological and economic consequences. {H}ere by (1) mapping the reads obtained by {I}llumina sequencing on a previously deposited {P}. parva genome from {G}ermany, (2) identifying {SNP}s and (3) creating a consensus sequence, we generated the first whole genome of an invasive {P}. parva population in {F}rance and compared it to a {G}erman population to explore patterns of genetic diversity, local adaptation, and potential signatures of pathogen resistance. {D}espite historical bottlenecks, our results reveal unexpectedly high levels of genomic diversity between these invasive populations. {W}e identify candidate loci linked to immune function and provide insights into the evolutionary dynamics of co-introduction. {T}hese findings offer a rare window into how invasive species maintain adaptability and how pathogens may co-evolve during range expansion. {B}eyond advancing our understanding of invasion biology, the genomic resources generated here pave the way for translational approaches, including the development of genome-editing strategies aimed at mitigating the impact of invasive species and their associated pathogens. {T}his work marks a critical step toward unraveling the complex interplay between genetics, ecology, and evolution in biological invasions.},
