A genetic paradox exists in invasion biology: how do introduced populations, whose genetic variation has probably been depleted by population bottlenecks, persist and adapt to new conditions? Lessons from conservation genetics show that reduced genetic variation due to genetic drift and founder effects limits the ability of a population to adapt, and small population size increases the risk of extinction. Nonetheless, many introduced species experiencing these same conditions during initial… 

Multiple Sources, Admixture, and Genetic Variation in Introduced Anolis Lizard Populations

It is proposed that introductions follow a sequential, two‐step process involving a reduction in genetic variation due to founder effects and population bottlenecks followed by an increase in Genetic variation if admixture of individuals from multiple native‐range sources occurs.

Post-colonization temporal genetic variation of an introduced fly, Rhagoletis completa

This study studied the population genetics of the walnut husk fly, Rhagoletis completa, which was introduced into California from the Midwestern US in the early 1900s and found that introduced populations showed greater temporal fluctuations in allele frequencies than native populations.

Comparing the genetic architecture and potential response to selection of invasive and native populations of reed canary grass

It is found that differences in the evolutionary potential of Phalaris populations are driven by differences in latitude, suggesting that selection also shapes the evolutionary trajectory of invasive populations.

Loss of genetic diversity and increased embryonic mortality in non‐native lizard populations

Loss of genetic diversity was accompanied by higher embryonic mortality in non‐native populations, suggesting that introduced populations are sufficiently inbred to jeopardize long‐term viability, but there was no statistical correlation between population‐level genetic diversity and average embryonic mortality.

Invading populations of an ornamental shrub show rapid life history evolution despite genetic bottlenecks.

It is found that these introductions have experienced large reductions in genetic diversity, but that increased growth and a latitudinal cline in flowering phenology have nevertheless evolved and are consistent with predictions for invasive plants.

Genetic Diversity and Thermal Performance in Invasive and Native Populations of African Fig Flies

Using genome sequences, it is shown that invasive populations of the African fig fly, Zaprionus indianus, have lower levels of genetic diversity compared to native populations, and that genetic diversity is lost more in regions of the genome with low recombination rates.

When invasion increases population genetic structure: a study with Centaurea diffusa

It is found that the total number of alleles and the number of private alleles was slightly higher in the native Eurasian range, and that allelic richness did not differ between the ranges, indicating overall levels of diversity were similar in Eurasia and North America.

Native drivers of fish life history traits are lost during the invasion process

The role of environmental and genetic diversity, and their prior evolutionary history (via haplogroup profiles) in shaping patterns of life history traits during biological invasion is characterized.

Genetic, Demographic and Ecological Factors Contributing to the Evolution of Anolis Lizard Populations

Evidence is provided that disturbance events such as hurricanes are catalysts of long-term, nonadaptive evolution when gene flow is limited, and the same island populations vary morphologically in the direction predicted by natural selection as a consequence of intraspecific competition.

Cryptic lineages and standing genetic variation across independent cane toad introductions

The roles of introduction history and genetic diversity in establishment success of cane toads across their introduced range are investigated and the importance of genetic sequencing in understanding biological introductions is highlighted, suggesting the role of standing genetic variation in range expansion.

Reduced genetic variation and the success of an invasive species.

Using microsatellite markers, it is shown that a population bottleneck has reduced the genetic diversity of introduced populations, and this loss is associated with reduced intraspecific aggression among spatially separate nests, and leads to the formation of interspecifically dominant supercolonies.

Introduced species as moving targets: changes in body sizes of introduced lizards following experimental introductions and historical invasions

Brown anoles are generally larger on islands where they have been introduced than on their native Caribbean islands, and are much larger on mainlands than on islands, indicating character release occurred at larger geographic scales as well.

Introduction: Population Biology, Evolution, and Control of Invasive Species

The role that population biology can play in understanding invasive species through life-history studies, demographic models, genetic considerations, and knowledge of the ecology and evolution of both invasive and native species in a community context is considered.

Hybridization as a stimulus for the evolution of invasiveness in plants?

This model does not represent the only evolutionary pathway to invasiveness, but is clearly an underappreciated mechanism worthy of more consideration in explaining the evolution ofinvasiveness in plants.

Rapid evolution of a geographic cline in size in an introduced fly.

Given their current scale, biotic invasions have taken their place alongside human-driven atmospheric and oceanic alterations as major agents of global change and left unchecked, they will influence these other forces in profound but still unpredictable ways.

The data are suggestive of microevolutionary adjustment of morphology in the Florida populations over the last 50 years, but a competing hypothesis that invokes multiple undetected introductions is not excluded.
