“…Among the mitochondrial genes investigated in Crustacea, the cytochrome oxidase I subunit (COI) gene has proved to be a very useful taxonomic and phylogenetic marker at the intergeneric level (e.g., Meyran et al, 1997;Wares, 2001). …”

The phylogenetic relationships of 14 species of the Antarctic amphipod families Epimeriidae and Iphimediidae were investigated using 553 bp of the gene for the mitochondrial cytochrome oxidase subunit I (COI) and 98 morphological characters. Both families are dominant members of the Antarctic benthic amphipod community. In contrast to previous studies, our molecular and morphological data suggest that the families Epimeriidae and Iphimediidae may not be sister taxa. Our study suggests that Iphimediidae are more closely related to Eusirus (Eusiridae) than to Epimeria (Epimeriidae). Phylogenetic analyses based on maximum parsimony (MP) and maximum likelihood (ML) indicate that the genera Iphimediella and Gnathiphimedia are not monophyletic.

“…The degree of intraspecific diversity observed for G. duebeni compares favourably with that of G. lacustris (Sars) (0.2-1.6%; and for populations of G. fossarum (Koch) distributed within a narrow geographic area varying in environmental calcium (E0.3-4.7%; . On a broader scale, populations of G. fossarum distributed across Europe are highly divergent (8-11%; Meyran et al, 1997;Mü ller, 2000) and a similar level of divergence (5-9%) was used to differentiate subspecies in G. pulex (Linnaeus) (Hadfield, 2002). Molecular variance in G. duebeni does in fact approach the minimum interspecific distances reported for other amphipod taxa (4-18%; France and Kocher, 1996), although minimum distances often appear to be higher for gammarids (9-12%; Meyran et al, 1997;Kelly et al, 2006).…”

Thus, values of 4% divergence within G. duebeni might arguably be substantial enough to indicate divergence into two biological species.…”

Phylogeography and environmental diversification of a highly adaptable marine amphipod, Gammarus duebeni

et al. 2007

Genetic diversity and phylogeographic population structure in the gammarid amphipod, Gammarus duebeni, were investigated across its broad latitudinal distribution in the NE and NW Atlantic by analysis of mitochondrial DNA sequence. Gammarus duebeni has exceptional tolerance of salinity change and inhabits environments ranging from marine to freshwater. The longstanding debate on whether there are distinct marine and freshwater subspecies was assessed by sampling populations from sites characterized by different salinities. Our sequence data demonstrates that there are two major lineages, with little internal geographic structuring. Evidence is provided to suggest a pre-glacial divergence of these two clades, involving segregation between a region historically associated with the freshwater form and the majority of the marine localities on both sides of the Atlantic. A modern contact zone between the marine and freshwater forms is proposed in western Britain.

“…although phylogenetic relationships w i t h i n G a m m a r i d e a a r e s t i l l p o o r l y understood, several authors have conducted relevant molecular phylogenetic studies (Meyran et al, 1997;ogarkov et al, 1997;sherbakov et al, 1998;sherbakov et al, 1999;englisch & Koeneman, 2001;englisch et al, 2003;Lörz & Held, 2004;Macdonald et al, 2005;hou et al, 2007;tomikawa et al, 2007a). Most recently, tomikawa et al (2007b) examined the phylogenetic relationships among selected Japanese gammaroideans using the nuclear 28s rrna gene focusing on families within Gammaroidea and suggested the monophyly of superfamily Gammaroidea and two families, anisogammaridae and Mesogammaridae, respectively.…”

Phylogenetic relationships of superfamily Gammaroidea (Amphipoda) and its allies from Japan

Abstract.-The current superfamilial classification of suborder Gammaridea, at least of the Japanese members, requires a full reassessment of their phylogenetic r e l a t i o n s h i p s . We i n v e s t i g a t e d 1 7 species representing six families in three superfamilies from Japan, based on partial sequences of the mitochondrial 16S rRNA and nuclear 28S rRNA genes. Members of superfamily Gammaroidea are characterized by having gammaridtype calceolus on their antennae, but our molecular analyses did not support the monophyly of Gammaroidea. The unique gammarid-type calceolus found in Gammaroidea may not be a synapomorphy for this group. Monophyly of the families s t u d i e d , e x c e p t f o r M e l i t i d a e , w a s supported by neighbor-joining, maximum parsimony, and maximum likelihood analyses. The molecular analyses revealed that during their evolutionary history, gammaroidean amphipods repeatedly switched between marine and freshwater habitats.
