Phylogeographical Analysis of Octopus Vulgaris (mollusca, Cephalopoda) in the Mediterranean: Insights from the Coi Mitochondrial Gene
This work reports a genetic data of Octopus vulgaris, marine species of high commercial value, from nineteen localities of Atlantic, Mediterranean and the Adriatic regions. We used mitochondrial DNA cytochrome c oxidase subunit I (COI) gene to investigate the genetic structure of common octopus. Our results indicated a significant genetic structuring in the study area (Phi = 0.136, P <0.001) an...
متن کاملOctopus vulgaris (Cuvier, 1797) in the Mediterranean Sea: Genetic Diversity and Population Structure.
The common octopus, Octopus vulgaris Cuvier 1797, is a largely exploited cephalopod species in the Mediterranean Sea and the Atlantic Ocean, as well as along the coasts of Africa, Brazil and Japan, where its taxonomic identity is still debated. The assessment of its genetic structure is a pressing need to correctly manage the resource and to avoid overfishing and collapsing of local stocks. Her...
متن کاملOctopus tetricus (Mollusca: Cephalopoda) as an ecosystem engineer ; Octopus tetricus (Mollusca: Cephalopoda) como ingeniero de ecosistemas
The Sydney octopus (Octopus tetricus) occurs in unusual numbers on a shell bed of its prey remains that have accumulated as an extended midden where additional octopuses excavate dens. Here, O tetricus are ecosystem engineers, organisms that modulate availability of resources to other species and to their own species by causing physical state changes in materials. A community of invertebrate gr...
متن کاملMultiple paternity in the common octopus Octopus vulgaris (Cuvier, 1797), as revealed by microsatellite DNA analysis
Two microsatellite DNA markers developed for the common octopus, Octopus vulgaris, were used to determine genotypes of four brooding female octopuses and 11 embryos sampled from their respective clutches, in order to confirm the multiple paternity hypothesis within this species. Two well-known reproductive behavioural patterns are apparently conflicting in mating outcome: the often-observed mul...
متن کاملMorphological and genetic evidence that Octopus vulgaris Cuvier, 1797 inhabits Amsterdam and Saint Paul Islands (southern Indian Ocean)
The coastal octopus at Saint Paul and Amsterdam Islands is Octopus vulgaris Cuvier 1797. Meristic and morphological characters, along with phylogenetic analysis of COI and COIII DNA sequences, were used to identify 11 animals collected in 2000 or 2001. The range of the species is therefore expanded to include the oceanic islands of the central southern Indian Ocean. The trees also depicted the ...
