For early-successional species, road and powerline cuts through forests provide refugia and source populations for invading adjacent forest gaps. [] Key Method For each of five linear habitat types, differing in width and disturbance frequency, we mapped all mounds located within ten 500 m segments. Mean mound density was lowest in narrow, infrequently-disturbed closed-canopy dirt road habitats (8.8 mounds/ha). For types with an opening in the forest canopy (i.e., open dirt road, gravel road, paved road and…

Distribution of the Red Imported Fire Ant Solenopsis invicta (Hymenoptera: Formicidae) in Central Florida Pastures

Time since soil disturbance was a significant predictor of S. invicta densities in both dry and wet seasons, with an increase in time since disturbance being associated with higher mound densities.

Does Habitat Management for Northern Bobwhites Benefit the Red Imported Fire Ant?

Red imported fire ants (Solenopsis invicta) have caused damage to agricultural, economic, and wildlife resources since their accidental introduction. Previous studies have suggested that red imported

Consequences of Forest Clear-Cuts for Native and Nonindigenous Ants (Hymenoptera: Formicidae)

This study is the first to document, through a controlled experiment, that clear-cutting alters ant species assemblages by increasing S. invicta and Pheidole spp.

Habitat alteration increases invasive fire ant abundance to the detriment of amphibians and reptiles

Results show that S. invicta abundance increases with habitat disturbance and that this increased abundance has negative consequences for amphibians that remain in altered habitats, and suggest that the presence of invasive S. Invicta may compromise the utility of cover boards and other techniques commonly used in herpetological studies in the Southeast.

Fire Ants, Cattle Grazing, and the Endangered Florida Grasshopper Sparrow

Densities of fire ant mounds differed among the five areas examined and were greater in areas with active cattle grazing programs than in areas without active grazing programs.

Ant community and habitat limit colony establishment by the fire ant, Solenopsis invicta

The results suggest that ant community assembly proceeds primarily by queen habitat choice and secondarily by filtering and competition, and that by landing in disturbed habitat with its reduced native ant population, newly mated fire ants queens increase their chances of successful colony establishment.

The Role of Habitat in the Persistence of Fire Ant Populations

Observations and experiments show that S. invicta colonies rarely persist in the native habitat of these pine forests, probably because they are not replaced when they die.

Does Prescribed Fire Facilitate Fire Ant Invasions in Coastal Prairies or Aid Management by Improving Mound Search Efforts?

Abstract We established a high-intensity prescribed-fire experiment in shrub-dominated coastal prairie to quantify (1) the proportion of Red Imported Fire Ant mounds that are likely to be missed by

Imported Fire Ant (Hymenoptera: Formicidae) Mound Distribution Relationships in Connection to the Heterogeneity of Ten Christmas Tree Farm Landscapes in Mississippi

Ten Christmas tree farms were selected as research sites across Mississippi. At each site a 10-percent inventory was established. Plots were chosen randomly, and all imported fire ant (IFA)

Distribution Patterns of Imported Fire Ants (Hymenoptera: Formicidae) on a Sheep and Goat Farm in Oklahoma

Results indicate that remotely sensed data in combination with publicly available U.S. Geological Survey data may be useful in predicting areas of high and low fire ant abundance at a field scale.




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.

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.

Contribution of Roads to Forest Fragmentation in the Rocky Mountains

The contribution of roads to forest fragmentation has not been adequately analyzed. We quantified fragmentation due to roads in a 30,213-ha section of the Medicine Bow-Routt National Forest in sout

Patterns in the Red Imported Fire Ant Settlement of a Louisiana Pasture: Some Demographic Parameters, Interspecific Competition and Food Sharing

In a densely populated pasture near Hammond, La., Solenopsis Invicta Buren mounds have an aggregate distribution with an average mound density of 0.0096/m, and Monomorium workers appeared to possess a powerful poison which, when spread in the air, had a strong repellent effect against S. invicta workers.

Roadside ditches as corridors for range expansion of the western harvester ant (Pogonomyrmex occidentalis Cresson)

The northeasternmost range extent of the western harvester ant (Pogonomyrmex occidentalis Cresson) occurs just east of the Missouri River in North Dakota. The earliest known records (1882) of this

Spread of weeds from a roadside into sclerophyll forests at Dartmouth, Australia.

Summary: The extent to which alien plants have spread from an old roadside into three sclerophyll forest communities was measured at a new dam site in Victoria, Australia. The data are discussed

Invasion of Polygyne Fire Ants Decimates Native Ants and Disrupts Arthropod Community

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.

Barriers as boundaries for metapopulations and demes of Peromyscus leucopus in farm landscapes

Salivary amylase data showed that studied subpopulations of white-footed mice were genetically very similar although the sample was intentionally biased toward demographic isolation, which suggested possible hierarchical relationships of metapopulations and genetic demes in the context of landscape ecology, management and conservation practice.
