We found several introduced species were volumetrically important salamander prey, & were responsible for resource differences between forest types & much of the seasonal fluctuation in food resources in both forest types.  We found one introduced ant species, Lasius alienus, among 7 native ant species.  Lasius alienus was the fourth most frequent & volumetrically important ant in salamander diets, occurring in 13% of samples with ants & accounting for an average of 10% of ant volume.  Lasius alienus was significantly more common than its native congener, L. nearctus , which occurred in only 2% of diet samples with ants.]1 aMaerz, J C1 aKaruzas, J M1 aMadison, D M1 aBlossey, B  uhttps://antkey.myspecies.info/zh-hans/content/introduced-invertebrates-are-important-prey-generalist-predator
