Nonnative species introductions are becoming more common, but long-term consequences of the novel pressures imposed by invaders on native species remain poorly known. The red imported fire ant, Solenopsis invicta, is an invasive species with potential global impact. Comparison of lizards across the invasive range within the United States reveals novel antipredator strategies and altered morphologies that mitigate potentially lethal attack by these ants, within 70 years of their introduction… Expand

Figures and Topics from this paper

The influence of invasive fire ants on survival, space use, and patterns of natural selection in juvenile lizards
TLDR
It is demonstrated that fire ant presence significantly explains patterns of lizard survival among populations and over small spatial scales within populations, and lizard habitat use was significantly altered in the presence of fire ants in high density. Expand
The consequences of lifetime and evolutionary exposure to toxic prey: changes in avoidance behaviour through ontogeny
TLDR
It is revealed how complex interactions can shape adaptive responses to multimodal impacts imposed by invaders: in the system, fire ants impose stronger bottom‐up selection than top‐down selection, with each selection regime changing differently across lizard ontogeny. Expand
Invasive ants influence native lizard populations
TLDR
Red imported fire ants likely affect reptiles with analogous life history strategies to those of fence lizards similarly and may have undesirable consequences for the biodiversity of reptiles in the southeastern United States and on other continents with established RIFA populations. Expand
Invasive Fire Ants Reduce Reproductive Success and Alter the Reproductive Strategies of a Native Vertebrate Insectivore
Background Introduced organisms can alter ecosystems by disrupting natural ecological relationships. For example, red imported fire ants (Solenopsis invicta) have disrupted native arthropodExpand
Rapid morphological change of a top predator with the invasion of a novel prey
TLDR
Evidence of rapid morphological change in the endangered snail kite across its North American range with the invasion of a novel prey, the island apple snail, suggests that evolutionary change may be imminent and underscores that even long-lived vertebrates can respond quickly to invasive species. Expand
Evading invaders: the effectiveness of a behavioral response acquired through lifetime exposure
TLDR
The data suggest that the higher percentage of responsive adults within invaded populations is the result of within-lifetime selection acting against unresponsive adults, and/or lifetime exposure to fire ants triggering the retention of this juvenile behavior into adulthood, rather than selection acting on a heritable trait across generations. Expand
Invasive ants alter foraging and parental behaviors of a native bird.
TLDR
The elimination of significant differences in body condition towards the end of the nestling period suggests that bluebird parents in control territories were able to make up the food deficit caused by fire ants, potentially by working harder to adequately provision their offspring. Expand
Sublethal effects of invasive fire ant venom on a native lizard.
TLDR
There is no evidence that lizards have evolved increased physiological resistance to fire ant venom, and lizards may instead rely on adaptive shifts in escape behavior and morphology following invasion to survive fire ant attack. Expand
A gastropod’s induced behavioral and morphological responses to invasive Carcinus maenas in Australia indicate a lack of novelty advantage
TLDR
Haustrum’s induced behavioral response to Carcinus may be more important in reducing predation than morphological defenses, and further propagate the invasive crab’'s impacts. Expand
Are Invasive Species Stressful? The Glucocorticoid Profile of Native Lizards Exposed to Invasive Fire Ants Depends on the Context
TLDR
Previous studies examining the stress response of wild vertebrates to various anthropogenic stressors are reviewed and discussed tounderscore the importance of considering context (the length, frequency, magnitude, and types of threat) when assessing these impacts. Expand

Invasion of Polygyne Fire Ants Decimates Native Ants and Disrupts Arthropod Community
TLDR
The ecological impacts of a polygyne fire ant invasion on ants and other surface—active arthropods at a field station in central Texas indicate that polygyn fire ants pose a substantial threat to the biodiversity of native arthropod communities. Expand
Adapting to an invasive species: toxic cane toads induce morphological change in Australian snakes.
  • B. Phillips, R. Shine
  • Biology, Medicine
  • Proceedings of the National Academy of Sciences of the United States of America
  • 2004
TLDR
Results provide strong evidence of adaptive changes in native predators as a result of the invasion of toxic prey, including two toad-vulnerable species and two species at low risk from toads. Expand
Red Imported Fire Ant Impacts on Wildlife: A Decade of Research
TLDR
The evidence suggests that mammals, birds and herpetofauna are vulnerable to negative impacts from fire ants, and some species are more likely to experience negative population-level impacts than other species. Expand
Evolutionary responses of natives to introduced species: what do introductions tell us about natural communities?
TLDR
The evidence for evolutionary responses of native species to novel community members is reviewed and how the effects of introduced species may differ from those caused by natural range expansions ofnative species is discussed. Expand
An invasive species induces rapid adaptive change in a native predator: cane toads and black snakes in Australia
  • B. Phillips, R. Shine
  • Biology, Medicine
  • Proceedings of the Royal Society B: Biological Sciences
  • 2006
TLDR
The results strongly suggest that black snake behaviour and physiology have evolved in response to the presence of toads, and have done so rapidly. Expand
Potential Global Range Expansion of the Invasive Fire Ant, Solenopsis invicta
TLDR
A dynamic, ecophysiological model of colony growth is used to predict the potential global range expansion of this invasive species, S. invicta, which has diverse detrimental impacts on recipient communities and has the potential to colonize numerous other regions. Expand
The morphology, and hence impact, of an invasive species (the cane toad, Bufo marinus ): changes with time since colonisation
TLDR
It is shown that both toad size and relative toxicity have decreased with time since colonisation, which strongly suggests that toads will exert their maximal impact on native predators when they first arrive in an area; the level of impact will then decline over time. Expand
An experimental study of the effects of weed invasion on lizard phenotypes
TLDR
Lizards in high invasion treatments hid more often during the day, were lighter in body mass, and females had lighter clutch masses and offspring than did those from moderate and low invasion enclosures, suggesting microhabitat degradation can drive a cascade of changes to an animal’s ecology. Expand
And the beak shall inherit - evolution in response to invasion.
TLDR
It is reported that native taxa in colonized regions may swiftly evolve to exploit such emancipated exotic species because of selection caused by invaders, and a native biota that initially permits invasion may rapidly respond in ways that ultimately facilitate control. Expand
