The Causes and Consequences of Ant Invasions
Invasions by non-native ants are an ecologically destructive phenomenon affecting both continental and island ecosystems throughout the world. Invasive ants often become highly abundant in theirExpand

Reduced genetic variation and the success of an invasive species.
Despite the severe ecological and economic damage caused by introduced species, factors that allow invaders to become successful often remain elusive. Of invasive taxa, ants are among the mostExpand

Patterns of spread in biological invasions dominated by long-distance jump dispersal: Insights from Argentine ants.
Invading organisms may spread through local movements (giving rise to a diffusion-like process) and by long-distance jumps, which are often human-mediated. The local spread of invading organisms hasExpand

COMPETITIVE MECHANISMS UNDERLYING THE DISPLACEMENT OF NATIVE ANTS BY THE INVASIVE ARGENTINE ANT
The Argentine ant (Linepithema humile) is a widespread invasive species that competitively displaces native ants throughout its introduced range. Although this pattern of displacement is well known,Expand

ROLE 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 interplayExpand

Abstract Predicting the success of biological invasions is a major goal of invasion biology. Determining the causes of invasions, however, can be difficult, owing to the complexity andExpand

Behavioral and Genetic Differentiation Between Native and Introduced Populations of the Argentine Ant
In this paper, we examine the hypothesis that reduced intraspecific aggression underlies the competitive prowess of Argentine ants in their introduced range. Specifically, we test three predictionsExpand

Trophic ecology of invasive Argentine ants in their native and introduced ranges
Although the ecological effects of invasions often become obvious soon after introduced species become established, more gradual effects may take years to manifest and can thus require long-term dataExpand

Mechanisms of dispersed central-place foraging in polydomous colonies of the Argentine ant
Many species of ants occupy multiple nests, a condition known as polydomy. Because of their decentralized structure, polydomous colonies may be removed from some of the constraints associated withExpand
