Abstract
Animals living in the Anthropocene search for mates facing a barrage of pollutants. Few studies consider pheromones from invasive species as pollution, but their central role in the lives of many animals indicates cross-reaction among historically allopatric relatives has potentially damaging impacts. We hypothesized the sex pheromone of sea lamprey (Petromyzon marinus), an invasive fish in the Laurentian Great Lakes, misguides mate search in native chestnut lamprey (Ichthyomyzon castaneus). In a field test, 100 % of female I. castaneus chose male odourants from P. marinus over conspecifics. Chemical analysis of water in which males were held confirmed both species signal with 3-keto petromyzonol sulfate but revealed higher release rates in P. marinus. Our results indicate sex pheromones from invasive species can be an influential type of pollution and underscore the conservation implications of studies on pheromone evolution.
