To test the combined effects of ecological and evolutionary forces on host-pathogen systems, we analyzed the spatiotemporal dynamics of a plant (Plantago lanceolata)-fungal pathogen (Podosphaera plantaginis) relationship for 12 years in over 4000 host populations. Disease prevalence at the metapopulation level was low, with high annual pathogen extinction rates balanced by frequent (re-) colonizations. Highly connected host populations experienced less pathogen colonization and higher pathogen extinction rates than expected; a laboratory assay confirmed that this phenomenon was caused by higher levels of disease resistance in highly connected host populations specialized FINLANDE 076MALPLA03 021ENVECO 344 6189 1289-1293 2014 0036-8075 https://www.documentation.ird.fr/hor/fdi:010080770 10.1126/science.1253621 0036-8075 [F B010080770] https://www.documentation.ird.fr/hor/fdi:010080770 https://www.documentation.ird.fr/intranet/publi/depot/2021-04-19/010080770.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2021-01-25 2021-04-20 fdi:010080770 fre
