Determination of the number of founders responsible for the establishment of invasive populations is important for developing biologically based management practices, predicting the invasive potential of species, and making inferences about ecological and evolutionary processes. The fire ant Solenopsis invicta is a major invasive pest insect first introduced into the USA from its native South American range in the mid-1930s. We use data from diverse genetic markers surveyed in the source…

Population genetic structure of a recent insect invasion: a gall midge, Asynapta groverae (Diptera: Cecidomyiidae) in South Korea since the first outbreak in 2008

Findings indicate that the high genetic diversity of the initial founding population and asexual reproduction would contribute to the successful invasion of A. groverae in novel environments.

Genetic Factors Associated with Variation in Abundance of the Invasive Yellow Crazy Ant (Anoplolepis gracilipes)

It is suggested that propagule pressure, reproductive mode and haplotype-specific effects do not appear to be associated with variation in abundance of the yellow crazy ant Anoplolepis gracilipes, and genetic factors may also beassociated with post-establishment population dynamics.

The genetic consequences of a demographic bottleneck in an introduced biological control insect

The data showed that the demographic bottleneck had a limited effect on the genetics of populations in the new range, and there was little genetic differentiation between the home and introduced ranges, and no evidence for a genetic bottleneck based on an analysis of heterozygosity with the microsatellite markers.

Propagule Pressure and Introduction Pathways of Bromus tectorum (Cheatgrass; Poaceae) in the Central United States

The results illustrate the population genetic consequences of relatively high propagule pressure (i.e., repeated immigrations to a new range from multiple sources) in the central United States.

Small founding number and low genetic diversity in an introduced species exhibiting limited invasion success (speckled dace, Rhinichthys osculus)

An introduced population of speckled dace from northern California, USA that has rapidly increased in abundance but remained restricted to a 25-km stretch of river since its introduction in the mid-1980s is studied to determine the extent to which genetic diversity loss has constrained invasion success.

Unusual chromosome numbers and polyploidy in invasive fire ant populations

Fire ants from invaded populations differed in chromosome morphology compared to those from native populations; the Florida and Taiwanese fire ant populations evinced greater variability in chromosome numbers and polyploidy variations; and the Taiwanese population exhibited significantly increased Ag-NOR signals in interphase cells.

Mating System, Introduction and Genetic Diversity of Bromus tectorum in North America, the Most Notorious Product of Evolution Within Bromus Section Genea

Molecular data suggest a reticulate speciation pattern (a netlike pattern of diversification) for the polyploid members of Genea in Bromus, and that B. tectorum is predominately self-pollinating.

The genome of the fire ant Solenopsis invicta

A phylogenetic analysis revealed that an ancestral vitellogenin gene first underwent a duplication that was followed by possibly independent duplications of each of the daughter viteLLogenins, possibly reflecting differential selection acting on the queen and worker castes.

Genetic diversity of populations of Brachypodium pinnatum (L.) P. Beauv. : expansive grass in a fragmented landscape

It is confirmed that isolation of calcareous grasslands in a landscape cannot prevent the expansion of B. pinnatum grasses because of the high generative dispersal ability and subsequent quick and extensive clonal growth of this species enables the successful establishment.

Microsatellite Analysis Reveals Population Structure and Population Expansion of Tecia solanivora1 in Solanum tuberosum in Colombia

It is suggested that movement of potatoes caused genetic homogenization in this species, and it is found that this species has undergone recent population expansion in Colombia.

Putative native source of the invasive fire ant Solenopsis invicta in the USA

This attempt to identify the source(s) of the red imported fire ant (Solenopsis invicta) in the southern USA utilizing data from three classes of genetic markers and employing Bayesian clustering simulations, assignment and exclusion tests, and phylogenetic and population genetic analyses concludes that the Mesopotamia flood plain near Formosa, Argentina represents the most probable source region.

Population Genetics of the Invasive Fire Ant Solenopsis invicta (Hymenoptera: Formicidae) in the United States

Bayesian analyses showed that study populations most distant from the claimed site of entry, Mobile, AL, have diverged most from the hypothetical founder population, consistent with an invasion scenario in which the ants spread outward from Mobile through repeated subfounder events.

Population genetics reveals origin and number of founders in a biological invasion

This work studied the invasion of the American bullfrog into Europe, a species that is considered a major cause of decline for native amphibians and found that most non‐native populations derive from less than six females.

Genetic variation and structure in native populations of the fire ant Solenopsis invicta: evolutionary and demographic implications

It is concluded that nominal S. invicta in its native range comprises multiple entities that are sufficiently genetically isolated and diverged to have embarked on independent evolutionary paths and to have come into secondary contact without regaining the capacity to freely interbreed.

Testing the role of genetic factors across multiple independent invasions of the shrub Scotch broom (Cytisus scoparius)

It is concluded that invasive populations have similar levels of high genetic diversity to native ranges; levels of admixture may vary across invasive populations so admixture does not appear to have been an essential requirement for invasion.

GENETIC ORIGIN OF MALE DIPLOIDY IN THE FIRE ANT, SOLENOPSIS INVICTA (HYMENOPTERA: FORMICIDAE), AND ITS EVOLUTIONARY SIGNIFICANCE

Three hypotheses are proposed, based on current knowledge of sex‐determining mechanisms in the Hymenoptera, to explain the loss of genetic diversity associated with high rates of diploid male production in S. invicta: allelic diversity was reduced during colonization of North America by a small founder group, genetic structuring of polygyne populations due to local inbreeding caused reduced allelic Diversity and/or increased homozygosity.

Species delimitation in native South American fire ants

The discovery of genetically distinct populations within both S. invicta and S. richteri suggests the presence of previously unrecognized (cryptic) species, implying that the group is actively radiating species and that morphological divergence generally does not keep pace with the development of reproductive isolation and neutral genetic divergence in this process.

PHYLOGEOGRAPHIC STRUCTURE OF THE FIRE ANT SOLENOPSIS INVICTA IN ITS NATIVE SOUTH AMERICAN RANGE: ROLES OF NATURAL BARRIERS AND HABITAT CONNECTIVITY

A major genetic break between S. invicta mtDNA haplotypes that coincides with the Mesopotamia wetlands region of South America, resulting in two higher level nested clade groupings is revealed and contrasting patterns of genetic differentiation within these two major groups are identified.

A Surprising Level of Genetic Diversity in an Invasive Wasp: Polistes dominulus in the Northeastern United States

The results support immediate identification of genetic diversity in an invasion population before the occurrence of secondary introductions as an essential part of managing and controlling invasive species.

Increased genetic variation and evolutionary potential drive the success of an invasive grass

The results show that repeated introductions of a single species may inadvertently create harmful invaders with high adaptive potential, and multiple immigration events may trigger future adaptation and geographic spread of a species population by preventing genetic bottlenecks and generating genetic novelties through recombination.
