Argentine Ant Affects Ant-Mimetic Arthropods: Does Argentine Ant Invasion Conserve Colouring Variation of Myrmecomorphic Jumping Spider?

Argentine ant invasion changed colour-polymorphic composition of ant-mimetic jumping spider Myrmarachne in southwestern Japan. In Argentine ant-free sites, most of Myrmarachne exhibited all-blackish colouration. In Argentine ant-infested sites, on the other hand, blackish morph decreased, and bicoloured (i.e. partly bright-coloured) morphs increased in dominance. Invasive Argentine ant drives a...

The worldwide expansion of the Argentine ant

Biological invasions by non-indigenous species are widely recognized as a significant component of human-caused global environmental change, often resulting in a significant loss in the economic value, biological diversity and function of invaded ecosystems (Elton, 1958; D’Antonio & Vitousek, 1992; Lodge, 1993; Vitousek et al., 1996, 1997). Studies of the phylogeographic structure (Stone & Sunn...

Native supercolonies of unrelated individuals in the invasive Argentine ant.

Kinship among group members has long been recognized as a main factor promoting the evolution of sociality and reproductive altruism, yet some ants have an extraordinary social organization, called unicoloniality, whereby individuals mix freely among physically separated nests. This type of social organization is not only a key attribute responsible for the ecological dominance of these ants, b...

Spatiotemporal patterns of intraspecific aggression in the invasive Argentine ant

The Argentine ant, Linepithema humile, is a widespread invasive species characterized by reduced intraspecific aggression within introduced populations. To illuminate the mechanisms underlying nestmate recognition in Argentine ants, we studied the spatial and temporal fidelity of intraspecific aggression in an introduced population of Argentine ants within which intraspecific aggression does oc...
