Journal ArticleDOI
A revision of the fire ants, Solenopsis geminata group (Hymenoptera: Formicidae, Myrmicinae).
Journal ArticleDOI
Effect of a founder event on variation in the genetic sex-determining system of the fire ant Solenopsis invicta.
TL;DR: It is concluded that diploid males have increased in frequency in introduced populations because of a loss of allelic diversity at the sex-determining locus (loci) of S. invicta, which has generated a substantial increase in the estimated segregational genetic load associated with production of sterile diploids males in introducing populations over the load in native populations.
Journal ArticleDOI
A review of the ants of the Florida Keys
TL;DR: A new survey of the ants of the Florida Keys increases the known fauna from 30 to 83 species, and the proportion of known exotics in the fauna is the highest for any area in the U.S.
Journal ArticleDOI
A Cross-Taxonomic Comparison of Insect Responses to Grassland Management and Land-Use Legacies

TL;DR: It is shown that land-use legacies can exert more influence on grassland insect community composition than current management, but the particular aspects of these land- use legacies that are important vary across insect taxa.
Journal ArticleDOI
Systematics and population genetics of fire ants (solenopsis saevissima complex) from argentina.
Kenneth G. Ross,James C. Trager +1 more
TL;DR: Genetic incompatibilities generally may be insufficient to create effective postzygotic barriers to interspecific gene flow in this group of ants, given that hybrids between these species in the United States suffer little apparent loss of fitness.
