“…Comparing the gene arrangement in U. orientalis to the Pancrustacean ground pattern (Boore et al, 1998), the trnH moves to the position between trnE and trnF in U. orientalis instead of nad4 and nad5. This order of U. orientalis is identical to the brachyuran mitogenome except for those of Eriocheir (Sun et al, 2005) and Xenograpsus testudinatus (Ki et al, 2009). In L. brevifrons, apart from an additional non-coding region, the mitogenome gene order of this species is consistent with U. orientalis.…”

Evolution and phylogeny of the mud shrimps (Crustacea: Decapoda) revealed from complete mitochondrial genomes

Background: The evolutionary history and relationships of the mud shrimps (Crustacea: Decapoda: Gebiidea and Axiidea) are contentious, with previous attempts revealing mixed results. The mud shrimps were once classified in the infraorder Thalassinidea. Recent molecular phylogenetic analyses, however, suggest separation of the group into two individual infraorders, Gebiidea and Axiidea. Mitochondrial (mt) genome sequence and structure can be especially powerful in resolving higher systematic relationships that may offer new insights into the phylogeny of the mud shrimps and the other decapod infraorders, and test the hypothesis of dividing the mud shrimps into two infraorders.Results: We present the complete mitochondrial genome sequences of five mud shrimps, Austinogebia edulis, Upogebia major, Thalassina kelanang (Gebiidea), Nihonotrypaea thermophilus and Neaxius glyptocercus (Axiidea). All five genomes encode a standard set of 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes and a putative control region. Except for T. kelanang, mud shrimp mitochondrial genomes exhibited rearrangements and novel patterns compared to the pancrustacean ground pattern. Each of the two Gebiidea species (A. edulis and U. major) and two Axiidea species (N. glyptocercus and N. thermophiles) share unique gene order specific to their infraorders and analyses further suggest these two derived gene orders have evolved independently. Phylogenetic analyses based on the concatenated nucleotide and amino acid sequences of 13 protein-coding genes indicate the possible polyphyly of mud shrimps, supporting the division of the group into two infraorders. However, the infraordinal relationships among the Gebiidea and Axiidea, and other reptants are poorly resolved. The inclusion of mt genome from more taxa, in particular the reptant infraorders Polychelida and Glypheidea is required in further analysis. Conclusions: Phylogenetic analyses on the mt genome sequences and the distinct gene orders provide further evidences for the divergence between the two mud shrimp infraorders, Gebiidea and Axiidea, corroborating previous molecular phylogeny and justifying their infraordinal status. Mitochondrial genome sequences appear to be promising markers for resolving phylogenetic issues concerning decapod crustaceans that warrant further investigations and our present study has also provided further information concerning the mt genome evolution of the Decapoda.

The diversity and abundance of cyclopoid copepods were investigated at four stations along the hydrothermal vent at Kueishantao Island, north-eastern Taiwan. Zooplankton samples were collected by surface tows. Qualitatively, 21 species of cyclopoids belonging to five genera and three families were observed. Our analysis revealed a number of abnormal protrusions (TLAs) on cyclopoid copepods, which were more frequent on the dorsal body surface and in members of the family Corycaeidae. The number of TLAs was highest at the hydrothermal vent plume (HVP) zone and among adult copepods. The potentially high levels of toxic minerals erupting from the hydrothermal vents as well as low pH and high temperatures may weaken the copepods' exoskeletons, thereby increasing susceptibility to infections, indicated by the HVP-related increase of tumoural processes. It is suggested that some of these abnormalities are related to the occurrence of symbiotic tantulocarids, a topic yet to be studied in this interesting environment.
