What we still don't know about invasion genetics

Abstract: Publication of The Genetics of Colonizing Species in 1965 launched the field of invasion genetics and highlighted the value of biological invasions as natural ecological and evolutionary experiments. Here, we review the past 50 years of invasion genetics to assess what we have learned and what we still don't know, focusing on the genetic changes associated with invasive lineages and the evolutionary processes driving these changes. We also suggest potential studies to address still-unanswered questions. We now… Show more

“…In contrast, if dominance or epistasis (which does not require heterozygous allele combinations) is the main mechanism of heterosis, selection may favor individuals with combinations of favorable alleles at multiple loci that increase fitness by complementing deleterious alleles (the dominance model) or through favorable epistatic interactions. Subsequently, the heterotic effects may be preserved in successive generations and potentially become fixed (Bock et al., 2015). Such heterotic gene combinations may contribute to the generation of transgressive phenotypes, which most frequently arise through the complementary action of additive loci (Rieseberg, Archer, & Wayne, 1999).…”

“…While early research on this question focused mainly on ecological aspects of invasions (Keane & Crawley, 2002; Levine, Adler, & Yelenik, 2004), the role of evolutionary changes in invasions has increasingly gained attention (Blossey & Nötzold, 1995; Lee, 2002; Müller‐Schärer, Schaffner, & Steinger, 2004; Prentis, Wilson, Dormontt, Richardson, & Lowe, 2008). But, despite significant advances in this field in recent years, a number of unresolved questions concerning the genetic processes associated with invasions remain (Bock et al., 2015). …”

“…DNA‐based studies can shed light on the eco‐evolutionary processes sustaining successful introductions and establishment of NIS (Bock et al., 2015; Rius, Turon, Bernard, Volckaert, & Viard, 2015), and guide policies directed towards the prevention or the management of NIS (Darling et al., 2017). They can provide evidence for the ‘spillover’ and ‘source–sink’ processes mentioned above, currently largely investigated with indirect approaches using field survey methods.…”

“…Invasive species are privileged models to analyse the evolution and adaptation of life history traits in new environments [1,2] While an increasing number of studies have documented adaptation during invasion in terrestrial species [3,4], few studies have been conducted in marine species to date [5][6][7]. Many marine species have a benthic sessile adult phase and disperse via a planktonic larval stage.…”
