Tramp species

In ecology, a tramp species is an organism that has been spread globally by human activities. The term was coined by William Morton Wheeler in the bulletin of the American Museum of Natural History in 1906, used to describe ants that “have made their way as well known tramps or stow-aways [sic] to many islands".^[1] The term has since widened to include non-ant organisms, but remains most popular in myrmecology. Tramp species have been noted in multiple phyla spanning both animal and plant kingdoms, including but not limited to arthropods, mollusca, bryophytes, and pteridophytes. The term "tramp species" was popularized and given a more set definition by Luc Passera in his chapter of David F William's 1994 book Exotic Ants: Biology, Impact, And Control Of Introduced Species.^[2]
