A pioneering longterm experiment on mesophotic macrofouling communities in the ...
Canning-Clode, João; Gizzi, Francesca; Braga-Henriques, Andreia; Ramalhosa, Patrício; Abreu, Pedro; Álvarez, Soledad; Biscoito, ManuelThe mesophotic zone represents one of our planet's largest and least explored biomes. An increasing number of studies evidence the importance of macrofouling species in marine ecosystems, but information on these communities and the factors influencing their structures at mesophotic depths remain poor. This lack of understanding limits our ability to predict anthropogenic impacts or conduct restoration operatio...
DNA barcoding of moon jellyfish (Cnidaria, Scyphozoa, Ulmaridae, Aurelia): two ...
Moura, Carlos J.; Magalhães, Bruno I.; Gonçalves, João M.Moon jellies are some of the most popular, widely distributed, and best-studied marine jellyfish. By the end of the past century only two or three Aurelia species were recognized, but with the rise of DNA barcoding studies, around thirty Aurelia species are presently accepted. Most of the species are morphologically indistinguishable and have restricted biogeography. We reveal, with COI, 16S, and ITS1-5.8S sequ...
Hundreds of genetic barcodes of the species-rich hydroid superfamily Plumulario...
Moura, Carlos J.; Lessios, Harilaos; Cortés, Jorge; Nizinski, Martha S.; Reed, John; Santos, Ricardo S.; Collins, Allen G.Marine hydroids are important benthic components of shallow and deep waters worldwide, but their taxonomy is controversial because diagnostic morphological characters to categorize taxa are limited. Their genetic relationships are also little investigated. We tested taxonomic hypotheses within the highly speciose superfamily Plumularioidea by integrating a classical morphological approach with DNA barcoding of ...
A molecular phylogenetic appraisal of the systematics of the Aglaopheniidae (Cn...
Moura, Carlos J.; Cunha, Marina R.; Porteiro, Filipe M.; Rogers, Alex D.The hydrozoan family Aglaopheniidae (Cnidaria) is widespread worldwide and contains some of the most easily recognizable hydroids because of their large colony size and characteristic microscopic structure. The systematics of the group has, however, been controversial and dedicated molecular analyses are lacking. We therefore analysed existing and new 16S rRNA sequences of Aglaopheniidae, in a total of 98 16S s...
Evolution of Nemertesia hydroids (Cnidaria: Hydrozoa, Plumulariidae) from the s...
Moura, Carlos J.; Cunha, Marina R.; Porteiro, Filipe M.; Yesson, Chris; Rogers, Alex D.Hydroid species from the genus Nemertesia develop some of the largest and most complex hydrozoan colonies. These colonies are abundant and ecologically important in both shallow and deep waters worldwide. Here, we analyse the systematics of most Nemertesia species from the NE Atlantic and Mediterranean using morphology and phylogenetic inferences of 16S rRNA haplotype data. Phylogeographical analysis revealed m...

Moura, Carlos J.; Cunha, Mariana R.; Porteiro, Filipe M.; Rogers, Alex D.Moura, C. J., Cunha, M. R., Porteiro, F. M. & Rogers, A. D. (2011). The use of the DNA barcode gene 16S mRNA for the clarification of taxonomic problems within the family Sertulariidae (Cnidaria, Hydrozoa). - Zoologica Scripta, 40, 520-537. The Sertulariidae are the most speciose family of the Hydrozoa, and their systematics are problematic. Here, 77 new 16S mtDNA sequence 'barcodes' of Atlantic and Mediterrane...
Polyphyly and cryptic diversity in the hydrozoan families Lafoeidae and Hebelli...
Moura, Carlos J.; Cunha, Marina R.; Porteiro, Filipe M.; Rogers, Alex D.The taxonomy of the putative superfamily Lafoeoidea (Hydrozoa), which includes the families Hebellidae and Lafoeidae, has been widely disputed at all systematic levels, mainly because these are morphologically simple and plastic animals. We used the molecular marker 16S mRNA to address phylogenetic relations of 'Lafoeoidea' hydroids mainly from shallow and deep waters of the north-east Atlantic and west Mediter...
