Argentine Ant Affects Ant-Mimetic Arthropods: Does Argentine Ant Invasion Conserve Colouring Variation of Myrmecomorphic Jumping Spider?
نویسندگان
چکیده
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 away native blackish ants. Disappearance of blackish model ants supposedly led to malfunction of Batesian mimicry of Myrmarachne.

Effects of Abiotic Factors on the Distribution and Activity of the Invasive Argentine Ant (Hymenoptera: Formicidae)
Environ. Entomol. 27(4): 822-8.33 (1998) ABSTRACT The Argentine ant, Linepithema humile (Mayr), has spread worldwide, often decimating native ant populations and other arthropod species in invaded areas. It is not known what abiotic and biotic conditions limit its distribution. We investigated the distribution of the Argentine ant in the Jasper Ridge Biological Preserve in northern California, ...
متن کاملEffects of Fragmentation and Invasion on Native Ant Communities in Coastal Southern California
We investigated the roles of habitat fragmentation and the invasion of an exotic species on the structure of ground-foraging ant communities in 40 scrub habitat fragments in coastal southern California. In particular, we asked: how do fragment age, fragment size, amount of urban edge, percentage of native vegetation, degree of isolation, and the relative abundance of an exotic species, the Arge...
متن کاملArgentine ant invasion associated with loblolly pines in the southeastern United States: minimal impacts but seasonally sustained.
Invasive ants are notorious for directly displacing native ant species. Although such impacts are associated with Argentine ant invasions (Linepithema humile) worldwide, impacts within natural habitat are less widely reported, particularly those affecting arboreal ant communities. Argentine ants were detected in North Carolina mixed pine-hardwood forest for the first time but were localized on...
متن کاملRole of Abiotic Factors in Governing Susceptibility to Invasion: a Test with Argentine Ants
Hypotheses concerning community-level vulnerability to invasion often emphasize biotic interactions but fail to consider fine-scale variation in the physical environment. In this study, the interplay between interspecific competition and abiotic factors is examined with respect to whether scrub habitats in southern California become invaded by the Argentine ant (Linepithema humile). Argentine a...
متن کاملHomogenization of ant communities in mediterranean California: The effects of urbanization and invasion
In coastal California, the invasive Argentine ant (Linepithema humile) displaces nearly all above ground foraging native ant species. The loss of native ants following invasion by Argentine ants homogenizes these faunas; natural habitats invaded by L. humile have lower beta diversity compared to comparable uninvaded areas. Argentine ant abundance in the seasonally dry mediterranean environments...
