The phylogenetic relationships of selected members the phylum Nemertea are explored by means six markers amplified from genomic DNA freshly collected specimens (the nuclear 18S rRNA and 28S genes, histones H3 H4, mitochondrial genes 16S cytochrome c oxidase subunit I). These include all previous regions used in earlier analyses nemerteans, therefore acting as a scaffold to which one could pinpoint any previously published study. Our results, based on static dynamic homology concepts under...
Although some clades of ribbon worms (phylum Nemertea) are consistently recovered with high support in molecular phylogenies, the placement and inter-relationships taxa have proven problematic. Herein, we performed phylogenetic analyses aimed at resolving these recalcitrant splits, using six loci (nuclear 18S rRNA, 28S histones H3 H4, mitochondrial 16S rRNA COI) for 133 terminals, particular emphasis on problematic families Hubrechtidae Plectonemertidae. Three different datasets were used...
Abstract This study describes the macrofauna of three beaches situated in central Gulf Gabès (Tunisia): Ouderef, and Zarrat. The has largest tides Mediterranean showed a wide intertidal zone. were sampled once during spring low June 2005. A transect was extended at each beach, from above drift line to below swash five levels; level six 0.05 m 2 replicates taken depth 30 cm sieved through 1‐mm mesh, organisms collected preserved. different physical environment. Sediment type medium sand...
The hoplonemertean Vieitezia luzmurubeae, gen. et sp. nov. is described from specimens collected in a national park on the north-west Iberian Peninsula, Parque Nacional Marítimo-Terrestre das Illas Atlánticas de Galicia. species, previously mistaken as Mediterranean species Tetrastemma vittigerum (Bürger, 1904), frequently associated with two common of sea squirt, Phallusia mamillata (Cuvier, 1815) and Ciona intestinalis (Linnaeus, 1767), inside which nemertean completes its life cycle. Some...
The exposed sandy beach of Ladeira (Corrubedo Bay, NW Spain) was sampled during seven years (2003–2009) after the Prestige oil spill (winter 2002–03), to determine interannual variations in macroinfaunal community two ways: (i) through ecological indices (species richness and abundances, Shannon's diversity Pielou's evenness) (ii) density most representative species. A clear zonation pattern found, consisting zones: supralittoral, occupied by talitrid amphipods, isopods insects, intertidal,...
A literature-based taxonomic catalogue of nemerteans (phylum Nemertea) from Spain and Portugal is provided, listing 75 species (12 Palaeonemertea, 24 Pilidiophora, 39 Hoplonemertea) belonging to 34 genera. This a low number compared with the approximately 400 listed in Europe. lack knowledge mainly due researchers interested phylum well-known difficulties its study. Geographic records are indicated for each species, some, comments included on certain biological aspects.
The nemertean Lineus acutifrons Southern (1913 Southern, R. 1913. Nemertinea. Proc R Ir Acad., 31: 1–20. [Google Scholar]) is a species rarely encountered in sandy beaches of Europe and only really known from its original short description. This has been found almost century later Galician (northwest Spain) re-described here. Data detailing internal morphology external anatomy, digital photographs are included. In addition, sequences the ribosomal gene 28S mitochondrial cytochrome oxidase I...
In most nemertean species, members of the two sexes aggregate before fertilization takes place. Few specific studies on mating behaviour nemerteans have been conducted but several observational reports indicate that important processes known from other organisms, such as sexual selection and sperm competition, may also be at work in nemerteans. Herein, we review some these observations discuss their possible implications. We produce a summary table reproduce observations, placing them an...
A new paranthurid isopod, Paranthura santiparrai sp. nov. is described from specimens collected in the 'El Cachucho' Marine Protected Area, southern Bay of Biscay. The species can be distinguished all known genus by absence eyes, native NE Atlantic nigropunctata and costana lack body pigmentation, antenna 1 pereopod morphology non-indigenous japonica (recently discovered Arcachon Bay) pleonites not fused mediodorsally. rediagnosed to accommodate taxon an identification key provided for...
Exposed sandy beaches are widespread coastal habitats with temporal and spatial variability. O Rostro beach (Galicia, north-west Spain) was the most severely affected in ‘Prestige’ oil spill (November 2002). Monitoring sampling conducted to study macroinfaunal composition structure after episode. The purpose of this survey characterize variations on over a yearly scale (2003–2007) determine recovery period. These data compared only available collected before (1995). Two zones where...
Abstract The North Atlantic deep-water polynoid worm Neopolynoe chondrocladiae is involved in an exceptional symbiotic relationship with two hosts: the carnivorous sponges Chondrocladia robertballardi and virgata. While this obligate relationship, its real nature unclear. We used a multidisciplinary approach to narrow down type of between symbiont hosts. Molecular connectivity analyses using COI 16S suggest that N. has high potential for dispersal, connecting sites hundreds kilometres apart,...
The marine ribbon worm genus Tetranemertes Chernyshev, 1992 currently includes three species: the type species T.antonina (Quatrefages, 1846) from Mediterranean Sea, T.rubrolineata (Kirsteuer, 1965) Madagascar, and T.hermaphroditica (Gibson, 1982) Australia. Seven new are described: T.bifrostsp. nov., T.ocelatasp. T.majinbuuisp. T.pastafariensissp. nov. Caribbean Sea (Panamá), species, T.unistriatasp. T.paulayisp. T.arabicasp. Indo-West Pacific (Japan Oman). As a result, an amended...
The phylum Nemertea is an important component of the benthic ecosystems Southern Ocean, but its biodiversity still relatively poorly known in Antarctic waters. There are few common and well-known nemertean species occurring shallow waters, these include congeneric Antarctonemertes valida (Bürger, 1893) riesgoae Taboada et al., 2013, two small brooding hoplonemerteans whose females lay eggs inside cocoons. A third member genus, belgica 1904), was reported only original description. Here we...
