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]

2021年1月1日 · Many tramp ant studies have focused on the two most highly invasive, economically important ants, namely, the red imported fire ant S. invicta and the Argentine ant L. humile. These are arguably the best studied ant species in the world and serve as models for studying patterns of tramp ant invasions and establishment.

Since it is easily spread as a stowaway among things transported by humans, it is referred to as a “tramp ant.” This species has become common in many areas along the Gulf Coast of Texas. It is not an aggressive invader of structures, but is commonly found along sidewalks, driveways, in and around flowerbeds, around foundations of buildings ...

Like several other invasive ants, such as the red imported fire ant (Solenopsis invicta), the big-headed ant (Pheidole megacephala), the little fire ant (Wasmannia auropunctata), and the Argentine ant (Linepithema humile), the yellow crazy ant is a "tramp ant", a species that easily becomes established and dominant in new habitat due to traits ...

These are often referred to as tramp ants, which broadly speaking is defined as exotic (non-native) ants transported with cargo by ships, trains, or other means. The first list of tramp ants was compiled more than a century ago, and comprised a total of 14 species. The number has since been extended to 42 [22]. Among the better

1995年9月23日 · Most transferred ants belong to the CRYPTIC, OPPORTUNIST, and GENERALIZED MYRMICINE functional groups, while there are no recorded transfers of army ants or leaf-cutting ants. Both invasive and human commensal 'tramp' ant species are nonrandom subsets of transferred ants.

Here, we document that the life history of Cardiocondyla closely resembles that of the more conspicuous tramp species, with polygyny, intranidal mating, budding, worker sterility, low genetic variability, and possibly also unicoloniality.

Tramp ants are a diverse group of invasive ant species which have become established widely across the globe. They arrive in Australia through many transport pathways, and once here can affect ecosystems, social and cultural values, and human health.

2021年10月3日 · Tramp ants are a diverse group of invasive ant species which have become established widely across the globe. They arrive in Australia through many transport pathways, and once here can affect ecosystems, social and cultural values, and human health.

Tramp ants share genetic, behavioural, and ecological attributes that affect their probability of entry, establishment and spread, ecological dominance, and high levels of impact. They routinely test Australian border defences. They are found in ships and planes and in a diverse range of cargoes. Many of these tramp ants
