Invasive Fire Ant (Solenopsis invicta) Predation of Eastern Fence Lizard (Sceloporus undulatus) Eggs

  title={Invasive Fire Ant (Solenopsis invicta) Predation of Eastern Fence Lizard (Sceloporus undulatus) Eggs},
  author={Christopher J. Thawley and Tracy Langkilde},
Abstract Invasive species are a threat to biodiversity, and understanding their impacts on native ecosystems is a research priority. Red Imported Fire Ants (Solenopsis invicta) are invasive in the southeastern United States and have multiple effects on a variety of native species. Some species and particular life stages (e.g., juveniles and eggs), may be especially vulnerable to fire ants, but research on these impacts has been limited. Fire ants occupy microhabitats used for nesting by Eastern… 

Invasive ants influence native lizard populations

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.

Southeastern US Snake Species are Vulnerable to Egg Predation by Red Imported Fire Ants (Solenopsis invicta)

Abstract: Invasion and spread of Red Imported Fire Ants (RIFA; Solenopsis invicta) is cited as a possible cause for enigmatic reptile declines in the southeastern United States. Reptiles are

Red imported fire ants (Solenopsis invicta) and seasonality influence community refuge use

Refuges are fundamental to animal ecology as refuge availability affects many levels of biological organization—from the behavior and physiology of individuals to the interspecific dynamics of a

Red imported fire ants (Solenopsis invicta) and seasonality influence community refuge use

Investigating community-wide refuge-use patterns in the context of two important ecological factors: invasive species and seasonality found evidence for a negative effect of S. invicta on vertebrate refuge use that was also influenced by season.

The influence of invasive fire ants on survival, space use, and patterns of natural selection in juvenile lizards

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.

Observations of Snakes Associated With Active Nests of Allegheny Mound Ant (Formica exsectoides) in Northeastern Pennsylvania

Abstract Refuge availability is an important component of snake ecology and conservation, yet we have limited understanding of the extent to which snakes use the nests of other animals for refuge.

Opportunistic Predation by Leaf-Cutting Ants (Hymenoptera: Formicidae) on a Wounded Baird's Tapir (Mammalia: Perissodactyla: Tapiridae) in Mexico

2 hypotheses are put forward: utilization by the leaf-cutting ants of these tissues as a resource that provides rare essential nutrients, and opportunistic sampling of polymicrobial communities associated with the skin of the wounded animal in search of new strains of their associated actinobacteria.

Food-burying behavior in red imported fire ants (Hymenoptera: Formicidae)

The results show that the food-burying behavior of Solenopsis invicta may be associated with the suppressed foraging activity, and the burying task may be carried out by certain groups of workers.

Inventory and Food Web of Arthropod Fauna Associated with Lagerstroemia spp.1 in Texas

Abstract. Sustainable, effective management of crapemyrtle bark scale, Acanthococcus lagerstroemiae (Kuwana), a non-native pest from Asia, probably will include biological control. Before this

Assessing the conservation risk of Sphaerodactylus notatus, the U.S. herpetofaunal species most vulnerable to sea level rise

While climate change and sea level rise threaten species across the globe, species in low-lying coastal regions, such as South Florida, are projected to face particularly severe threats. One such




Habitat restoration that decreases red imported fire ant abundance may be the most cost-effective and long-term method of decreasing impacts from red importedFire ants.

Red imported fire ant predation on eggs of the eastern fence lizard

Invasive species, whether introduced accidentally or intentionally, have caused significant ecological and economic impacts across a variety of habitats (Pimental, Zuniga and Morrison, 2005).

Holding ground in the face of invasion: native fence lizards (Sceloporus undulatus) do not alter their habitat use in response to introduced fire ants (Solenopsis invicta)

It is found that lizards do not alter their habitat use following S. invicta invasion, nor do they spatially avoid their mounds, and this was only evident in naive or recently...

Red Imported Fire Ant Impacts on Wildlife: A Decade of Research

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.

Biology and control of imported fire ants.

The purpose here is to review this research, although because of space limitations, much of the recent work concerning the chemical toxicology and persistence of mirex, the chemical currently used for control of imported fire ants.

Invasion of red imported fire ants (Hymenoptera: Formicidae): microgeography of competitive replacement

The invasion of Brackenridge Field Laboratory, Austin, Texas, by the multiple-queen form of the red imported fire ant, Solenopsis invicta Buren, was monitored for 3 yr. This invasion provides a rare

Distribution of the Fire Ants Solenopsis invicta and S. geminata (Hymenoptera: Formicidae) in Northern Florida in Relation to Habitat and Disturbance

S. geminata is common throughout the longleaf pine forest, both in mature stands and clearcut replanted areas, but it is nearly absent from heavily disturbed or pond-side sites occupied by S. invicta.

Laboratory Observations of Red Imported Fire Ant (Hymenoptera: Formicidae) Predation on Reptilian and Avian Eggs

Red Imported Fire Ants may have a more prominent role in the decline of native reptilian species than was previously thought and further studies are necessary to determine the true impact.

Effects of the Argentine Ant on Arthropod Fauna of Hawaiian High‐Elevation Shrubland

Invasion of the Argentine ant has locally reduced the abundance of many endemic species in the shrubland ecosystem and appears to have the potential to invade a much larger area of Haleakala National Park than it now occupies.

Biogeographic effects of red fire ant invasion

The results suggest that the effects of S. invicta on native ant communities are pervasive: not only does the presence of the red imported fire ant reduce species density at local scales, it alters the co-occurrence patterns of surviving species at a biogeographic scale.
