Caprella mutica (Crustacea, Amphipoda) has been widely introduced to non‐native regions in the last 40 years. Its native habitat is sub‐boreal northeast Asia, but in the Northern Hemisphere, it is now found on both coasts of North America, and North Atlantic coastlines of Europe. Direct sequencing of mitochondrial DNA (cytochrome c oxidase subunit I gene) was used to compare genetic variation in native and non‐native populations of C. mutica. These data were used to investigate the invasion… 

Caprella mutica in the Southern Hemisphere: Atlantic origins, distribution, and reproduction of an alien marine amphipod in New Zealand

Direct sequencing of C. mutica mitochondrial DNA identified 3 haplotypes: 1 unique to New Zealand and 2 previously found in non-native Atlantic populations, which suggest Lyttelton may be the introduction site in New Zealand.

Global Phylogeography of the Widely Introduced North West Pacific Ascidian Styela clava

A fragment of the cytochrome oxidase subunit I mitochondrial gene is sequenced from a total of 554 individuals to examine the genetic relationships of 20 S. clava populations sampled throughout the introduced and native ranges, in order to investigate invasive population characteristics.

Unravelling the origin and introduction pattern of the tropical species Paracaprella pusilla Mayer, 1890 (Crustacea, Amphipoda, Caprellidae) in temperate European waters: first molecular insights from a spatial and temporal perspective

Direct sequencing of mitochondrial (COI and 16S) and nuclear (28S and ITS) genes are used to compare genetic differences in presumed native and introduced populations in order to infer its introduction pattern and to shed light on the native range of this species.

Genetic Diversity in Introduced Golden Mussel Populations Corresponds to Vector Activity

It is suggested that the intensity of human-mediated introduction vectors influences patterns of genetic diversity in non-indigenous species.

Phylogeography and population genetic structure of an exotic invasive brine shrimp, Artemia Leach, 1819 (Crustacea : Anostraca), in Australia

Native American Artemia franciscana has become an introduced species in the Old World due to the rapid development of the aquaculture industry in Eurasia. The recent colonisation of A. franciscana in

Hidden diversity and cryptic speciation refute cosmopolitan distribution in Caprella penantis (Crustacea: Amphipoda: Caprellidae)

This study provides the first evidence of cryptic speciation in the family Caprellidae, and questions the validity of some traditional morphological characters used to delimit species in the genus Caprella.


Results indicate that the three Nipponacmea species can be efficiently identified by DNA barcoding and are possibly due to the local and regional hydrographic conditions in the Yangtze River estuary, the large salt marsh in the river delta and difference of temperature between northern and southern China.

The Impact of the Colonization of the Invasive American Artemia franciscana (Crustacea: Anostraca) on Genetic Differentiation in the United Arab Emirates (Asia)

The authors' findings have confirmed the colonization of both localities by A. franciscana and documented the excess of both recent and historical mutations in the COI gene pool of invasive AWWR Artemia throughout establishment in the new environment.

Colonization and dispersal patterns of the invasive American brine shrimp Artemia franciscana (Branchiopoda: Anostraca) in the Mediterranean region

Results suggest natural dispersal, potentially via flamingos, between two Spanish populations of the brine shrimp Artemia franciscana, which is likely to be admixed from both GSL and SFB because of multiple introductions.

Cryptic diversity and mtDNA phylogeography of the invasive demon shrimp, Dikerogammarus haemobaphes (Eichwald, 1841), in Europe

The regions of the Black, Caspian, and Azov seas are known for being both (i) the place of extensive crustacean radiation dated to the times of Paratethys and Sarmatian basins, and (ii) present



Deeply divergent lineages of the widespread New Zealand amphipod Paracalliope fluviatilis revealed using allozyme and mitochondrial DNA analyses

Although population differences were clearly shown by allozyme and mtDNA analyses, individuals were morphologically indistinguishable, suggesting that, as in North American and European taxa, morphological conservatism may be prevalent among New Zealand's freshwater amphipods.

Multiple origins and incursions of the Atlantic barnacle Chthamalus proteus in the Pacific

Genetic variation in native and introduced populations was characterized and genetic matches between regions were searched for to determine if there were multiple geographical sources and introduction points for this barnacle, confirming a multigeographical origin for the Pacific populations.

Distribution of the introduced amphipod, Caprella mutica Schurin, 1935 (Amphipoda: Caprellida: Caprellidae) on the west coast of Scotland and a review of its global distribution

The local scale distribution of C. mutica is potentially limited by the availability of suitable transportation vectors during the dispersal phase rather than by physical environmental factors following release, which suggests that the species has not yet been found in natural habitats.

Cryptic species diversity and evolution in the amphipod genus Hyalella within central glaciated North America: a molecular phylogenetic approach

Evidence suggests that diversification has arisen as a consequence of both isolation in different glacial refugia and hab - itat specialization in populations of the amphipod crustacean Hyalella azteca, which appears to have originated as early as the mid-Miocene.

Gene genealogy analyses point to aquaculture as a major vector of introduction and spread in Europe but implicate maritime traffic in promoting recurrent migration events from the native range to Australasia, suggesting different processes of introduction in the two regions.

Multiple introductions promote range expansion of the mollusc Cyclope neritea (Nassariidae) in France: evidence from mitochondrial sequence data

A comprehensive study based on mitochondrial gene sequences of the five recently colonized French bays as well as 14 populations located in the recognized native range of Cyclope neritea shows that recurrent human‐mediated introductions from several geographical areas in the native range may be a source for the French Atlantic populations.

Changes in genetic structure of North American Bythotrephes populations following invasion from Lake Ladoga, Russia

The results provide additional evidence of the presence of an invasion corridor that allows Urasian and Ponto-Caspian species to be introduced into North American freshwater ecosystems, and show that founder effects can erode over time following establishment of invasive species.

Characterising invasion processes with genetic data: an Atlantic clade of Clavelina lepadiformis (Ascidiacea) introduced into Mediterranean harbours

The results support the hypothesis that both clades evolved allopatrically in the two seas, and that a recent colonisation of Mediterranean marinas from the Atlantic was caused by ship-hull transport.

The voyage of an invasive species across continents: genetic diversity of North American and European Colorado potato beetle populations

Investigating the invasion of the Colorado potato beetle from North America to Europe found a similar, high level of population structure and low gene flow among populations on both continents, suggesting a single successful founder event.

Morphological and molecular differentiation of invasive freshwater species of the genus Corbicula (Bivalvia,Corbiculidea) suggest the presence of three taxa in French rivers

Populations of Corbicula from France and the Netherlands were analysed morphologically and genetically to quantify the degree of species and/or population differentiation, and indicate that there are two distinct species, identified as C. fluminalis and C.Fluminea, in the two countries.
