Inconsistency for the niche breadth invasion success hypothesis in aquatic invertebrates

We compared variation in δ13C and δ15N, or isotopic niche, in the tissues of matched pairs of highly successful and less successful (respectively) freshwater and marine aquatic invasive species: violet tunicate Botrylloides violaceus and golden star tunicate Botryllus schlosseri from the northwest Atlantic coast; spiny waterflea Bythotrephes longimanus and fishhook waterflea Cercopagis pengoi from the Great Lakes basin; and Pacific oyster Crassostrea gigas and eastern oyster Crassostrea virginica from the northeast Pacific coast.

© 2017 Association for the Sciences of Limnology and Oceanography Comparison of highly successful and less successful invasive species can highlight traits that are associated with invasion success, and indicate the associated risk of further establishment or invasion from novel species.

Comparison with the literature suggested that a broad dietary niche is less crucial for widespread distribution of aquatic invasive invertebrates than it is for vertebrates (i.e., fishes).
