“…Bryocyclops). Wyngaard et al (2010) mentioned the absence of tropical Amphi-Pacific disjunctions in Mesocyclops Sars, 1914 (Cyclopidae) clades. Ballast water in boats (now and during long histories of trans-Pacific seafaring) are considered as important vectors, but copepod species also get introduced with aquatic plants or animals in aquaculture (Reid and Pinto-Coelho, 1994 (Bayly, 1992).…”

“…The lower taxonomic level relationships have been resolved using the ITS2 of the nuclear rDNA gene cluster (Wyngaard et al 2010). Combine with mitochondrial genes and nucleic genes would produce more reliable species description than those based on a single gene (Dupuis et al 2012).…”

In the present investigation to isolate freshwater calanoid copepods (Diaptomus sicilis) was characterized and identify the organisms by 18S rRNA sequencing. Plankton samples containing D. sicilis were collected during January 2014 (Post-monsoon) from Madippakkam Lake (12°57'41"N80°11'27"E) Chennai, Tamil Nadu. Immediately after sampling, specimens for genetic analyses were fixed in 95% ethyl alcohol. The total DNA was extracted from the individual copepod D. sicilis using Qiagen Blood tissue kit. The nuclear small subunit 18S rRNA gene was amplified using the Universal primer LCO -1490 (5'-GGTCAACAAATCATAAAGATATTGG-3') and HCO-2198 (5'-TAAACTTCAGGGTGACCAAAAAATCA-3'). PCR products were loaded onto a 1% TAE agarose gel. Sequences were carried out an automated sequencer. The nucleotide sequence of 1282 base pair region of 18S rRNA was determined for D. sicilis. The similarity of sequences of D. sicilis was retrieved by BLASTn program and maximum identity and E-value was 76% and 0.00, respectively. The PCR products of D. sicilis individuals showed 80% similarity with the partial nuclear small subunit 18S rRNA gene region of other calanoid copepods. Based on molecular data the freshwater Calanoid copepods showed different algorithms and similar types of topologies useful for designing molecular analyses using phylogeny tree construction.Present molecular studies on the relationship of D. sicilis with other freshwater calanoid copepods indicate that this species is close to D. castor followed by D. keniraensis.

“…Analyses were performed following a hierarchical taxonomical approach: (i) conservative nuclear ribosomal DNA genes (18S and 28S), which are widely used to resolve relationships at the genusand family-rank in copepods (e.g. : Bucklin et al, 2003;Braga et al, 1999;Wyngaard et al, 2010;Blanco-Bercial et al, 2011), were used to investigate the taxonomical rank to be assigned to the taxon Occidodiaptomus in the frame of the family Diaptomidae, (ii) species grouping based on a matrix of morphological characters was compared to that obtained through molecular analyses, (iii) fragments of the mitochondrial genes 16S and Cyt-b were used to check for the monophyly of Occidodiaptomus and to investigate the relationships among the taxa belonging to it. Finally, the COI gene was chosen as an additional mitochondrial marker for further testing the monophyly of the clades singled out with the other mitochondrial markers in the only H. ingens s.l.…”

a b s t r a c tOur comprehension of the phylogeny and diversity of most inland-water crustaceans is currently hampered by their pronounced morphological bradytely, which contributed to the affirmation of the ''Cosmopolitanism Paradigm'' of freshwater taxa. However, growing evidence of the existence of cryptic diversity and molecular regionalism is available for calanoid copepods, thus stressing the need for careful morphological and molecular studies in order to soundly investigate the systematics, diversity and distribution patterns of the group.Diaptomid copepods were here chosen as model taxa, and the morphological and molecular diversity of the species belonging to the west-Mediterranean diaptomid subgenus Occidodiaptomus were investigated with the aim of comparing the patterns of morphological and molecular evolution in freshwater copepods. Three species currently lumped under the binomen Hemidiaptomus (Occidodiaptomus) ingens and two highly divergent clades within H. (O.) roubaui were distinguished, thus showing an apparent discordance between the molecular distances recorded and Occidodiaptomus morphological homogeneity, and highlighting a noteworthy decoupling between the morphological and molecular diversity in the subgenus.Current Occidodiaptomus diversity pattern is ascribed to a combined effect of ancient vicariance and recent dispersal events. It is stressed that the lack of sound calibration points for the molecular clock makes it difficult to soundly temporally frame the diversification events of interest in the taxon studied, and thus to asses the role of morphological bradytely and of accelerated molecular evolutionary rates in shaping the current diversity of the group.
