“…Combining nuclear DNA and organellar markers has traditionally improved the understanding of invasive processes, and it is becoming clear that including vertically transmitted endosymbiont or parasitic organisms can provide new insight into the origins of invasive species as well as the diseases they carry (Gupta et al 2014;Mobegi et al 2014). The addition of mtDNA provides information on introgression patterns between diverged populations or subspecies because mtDNA genomes track maternal lineages (McCormick et al 2014).…”

The rate of biological invasions is expected to increase as the effects of climate change on biological communities become widespread. Climate change enhances habitat disturbance which facilitates the establishment of invasive species, which in turn provides opportunities for hybridization and introgression. These effects influence local biodiversity that can be tracked through genetic and genomic approaches. Metabarcoding and metagenomic approaches provide a way of monitoring some types of communities under climate change for the appearance of invasives. Introgression and hybridization can be followed by the analysis of entire genomes so that rapidly changing areas of the genome are identified and instances of genetic pollution monitored. Genomic markers enable accurate tracking of invasive species’ geographic origin well beyond what was previously possible. New genomic tools are promoting fresh insights into classic questions about invading organisms under climate change, such as the role of genetic variation, local adaptation and climate pre-adaptation in successful invasions. These tools are providing managers with often more effective means to identify potential threats, improve surveillance and assess impacts on communities. We provide a framework for the application of genomic techniques within a management context and also indicate some important limitations in what can be achieved.

“…This hybrid zone is young, with mice having colonized this area around 3000 years ago [ 19 , 20 ]. Hybridization in the wild between M. m. domesticus and M. m. castaneus is best known from one study of an introduced population in California [ 21 ] and one in New Zealand [ 22 ]. Within the native range, other possible domesticus/castaneus hybrid zones in Iran [ 23 – 25 ] and in Indonesia [ 26 ] have produced only preliminary results, because these regions are complex, supporting multiple (and potentially undescribed) subspecies [ 24 ], and because comprehensive nuclear loci have not been used to look at the levels of admixture across the genomes.…”

“…Across most of the two main islands, and on most offshore islands, M. m. domesticus mitochondrial haplotypes predominate. In the southern South Island, however, one M. m. castaneus mitochondrial DNA (mtDNA) is solely found, with a narrow ‘hybrid’ zone around 50 km wide separating the M. m. castaneus to the south and M. m. domesticus to the north [ 22 , 55 ]. The same M. m. castaneus mtDNA haplotype is also present in the lower North Island around the Wellington region, and a second one is the only mtDNA haplotype so far identified on Chatham Island.…”

“…All studies to date have found a predominance of M. m. domesticus nuclear ancestry across the country, including ‘hybrid’ populations containing unquantified mixes of the other two subspecies present but insufficiently characterized. Of the few nuclear markers that have been sequenced previously, all mice, regardless of mitochondrial haplotype, have had predominantly M. m. domesticus ancestry, though some mice in the upper South Island also have had M. m. musculus markers [ 22 ]. No M. m. castaneus nuclear ancestry has yet been detected in New Zealand mice.…”

The house mouse (Mus musculus) provides a fascinating system for studying both the genomic basis of reproductive isolation, and the patterns of human-mediated dispersal. New Zealand has a complex history of mouse invasions, and the living descendants of these invaders have genetic ancestry from all three subspecies, although most are primarily descended from M. m. domesticus. We used the GigaMUGA genotyping array (approximately 135 000 loci) to describe the genomic ancestry of 161 mice, sampled from 34 locations from across New Zealand (and one Australian city—Sydney). Of these, two populations, one in the south of the South Island, and one on Chatham Island, showed complete mitochondrial lineage capture, featuring two different lineages of M. m. castaneus mitochondrial DNA but with only M. m. domesticus nuclear ancestry detectable. Mice in the northern and southern parts of the North Island had small traces (approx. 2–3%) of M. m. castaneus nuclear ancestry, and mice in the upper South Island had approximately 7–8% M. m. musculus nuclear ancestry including some Y-chromosomal ancestry—though no detectable M. m. musculus mitochondrial ancestry. This is the most thorough genomic study of introduced populations of house mice yet conducted, and will have relevance to studies of the isolation mechanisms separating subspecies of mice.
