  1. Naïve laboratory bred first generation offspring from three-spined sticklebacks Gasterosteus aculeatus from lake Großer Plöner See, Germany (DE), and Lake Skogseidvatnet, Norway (NO), were infected with Schistocephalus solidus parasites from different geographic locations or sham-exposed as controls. The top row indicates S. solidus geographic cluster; abbreviations in the second row refer to S. solidus sampling sites (OBB: Obbola, Sweden; GOT: Gotland, Sweden; NST: Neustädter Binnenwasser, Germany; SP: Xinzo de Limia, Spain; IBB: Ibbenbürener Aa, Germany; ECH: Vancouver Island, Canada; NU: North Uist, Scotland; ISC: Lake Myvatn, Iceland; SKO: Lake Skogseidvatnet, Norway; control: sham-exposed control). Capital letters indicate fish families (offspring of one pair of sticklebacks), lower case letters indicate worm sibships (offspring of one pair of worms). Per treatment, i.e. fish family x worm sibship combination, 100 copepods and subsequently 20 fish were exposed to single infective S. solidus larvae or sham-exposed; combinations with ‘na’ were not included in the respective analysis. Numbers in columns of S. solidus exposed fish indicate the number of infected individuals. We used contrast 1 to test for host, parasite and interaction effects; contrast 2 and contrast 3 were used to test parasite effects on a broader geographic scale. NO data in contrast 1 is a data subset of contrast 3. We accounted for multiple testing
