Supplemental data for: Effects of spawning habitat on the performance of age-0 pumpkinseed sunfish (Lepomis gibbosus) ecotypes in a Canadian shield lake

We address a key uncertainty about the effects of non-ancestral natal conditions on juvenile performance to clarify the role of juveniles in the formation of novel fish biodiversity in postglacial Canadian lakes. We compared littoral and pelagic ecotypes of pumpkinseed sunfish (Lepomis gibbosus) to investigate performance over the natal summer of age-o juveniles spawned either in the ancestral littoral habitat or in two other lake habitats: exposed rocky littoral shorelines and submerged rocky shoals offshore in the pelagic habitat.
