New nuclear markers and exploration of the relationships among Serraniformes (Acanthomorpha, Teleostei): the importance of working at multiple scales.
The complete nucleotide sequence of the mitochondrial DNA of the agnathan Lampetra fluviatilis: bearings on the phylogeny of cyclostomes.
The mtDNA sequence of L. fluviatilis was used in combination with relevant mtDNA sequences for an approach to the hagfish/lamprey relationships using the maximum-parsimony, neighbor-joining, and maximum-likelihood methods, and the data collected do not support the vertebrate or the cyclostome hypothesis.
Is the Species Flock Concept Operational? The Antarctic Shelf Case
The present study contradicts the paradigm that marine species flocks are rare and proposes a new protocol which includes an iterative fine-tuning of the monophyly and endemicity criteria in order to discover unsuspected flocks.
Complete mitochondrial DNA of the hagfish, Eptatretus burgeri: the comparative analysis of mitochondrial DNA sequences strongly supports the cyclostome monophyly.

Molecular data, i.e., results and those obtained using nuclear genes, conclude that hagfishes and lampreys form a clade, and unequivocally supported the monophyly of cyclostomes.
Comprehensive sampling reveals circumpolarity and sympatry in seven mitochondrial lineages of the Southern Ocean crinoid species Promachocrinus kerguelensis (Echinodermata)
The phylogeny of Promachocrinus phylogroups reveals two principal clades that may represent two different cryptic species with contrasting demographic histories, suggesting multiple glacial refugia in the Southern Ocean.
Tracking the elusive monophyly of nototheniid fishes (Teleostei) with multiple mitochondrial and nuclear markers.
Phylogenetic footprints of an Antarctic radiation: the Trematominae (Notothenioidei, Teleostei).

The genus Artedidraco is not monophyletic, confirming the preliminary relationships found by Derome et al. ( 2002), and there is a trend toward a decrease in the number of epipleural ribs and an increase in number of pleural ribs along the tree.
The complete nucleotide sequence of the mitochondrial DNA of the dogfish, Scyliorhinus canicula.
The phylogenetic analysis confirms that the Chondrichthyes are the sister group of the Osteichthyes, and the main features of the mtDNA of osteichthyans were established in the common ancestor to chondrichthyans and osteICHthyans.
