Abstract
There is increasing evidence that closely related species have contrasting ecosystem effects, but very little is known about the temporal scale of these effects. When organisms' ecosystem-effects persist beyond or emerge after their presence in the ecosystem, this might increase the potential for eco-evolutionary feedbacks to accompany evolutionary diversification. Here we studied lab-raised whitefish of a benthic-limnetic species pair from a postglacial adaptive radiation to test whether closely related species have contrasting effects on mesocosm ecosystems (hereafter ecosystem effects). We found that the presence of whitefish (ecological effect) had strong effects on some ecosystem components, for example by reducing snail and mussel abundance and increasing phytoplankton abundance. Whitefish species had contrasting effects (evolutionary effect) on benthic algal cover, dissolved organic carbon, and zooplankton community composition, but these effects only emerged several months after whitefish were rem...
