Ports are gateways for many marine organisms transported by ships worldwide, especially non-indigenous species (NIS). In this study carried out in North Iberian ports (Cantabrian Sea, Bay of Biscay) we have observed 38% of exotic macroinvertebrates. Four species, namely the barnacle Austrominius modestus, the tubeworm Ficopomatus enigmaticus, the Pacific oyster Crassostrea gigas and the pygmy mussel Xenostrobus securis, exhibited clear signs of invasiveness. A total of 671 barcode (cytochrome oxidase subunit I or 18S rRNA) genes were obtained and confirmed the species status of some cryptic NIS. Negative and significant correlation between diversity estimators of native biota and proportion of NIS suggests biotic resistance in ports. This could be applied to management of port biota for contributing to prevent the settlement of biopollutants in these areas which are very sensitive to biological invasions.

Abstract Pholas dactylus is a historically valuable species with a relevant role in both environmental and biotechnological fields. It has become scarce in Europe due to habitat destruction and human overuse. This species is currently undergoing steep population declines, which have caused local extinction and/or distribution range contraction. Six different localities were sampled between the southern central region of the Bay of Biscay (Spain) and the Black Sea (Bulgaria and Romania) with the aim of describing for the first time its genetic variation patterns and assisting its conservation. Analyses using the mitochondrial Cytochrome Oxidase I gene revealed a high number of unique haplotypes in the Atlantic and Black Sea areas and significant genetic structuring ( F ST = 0 . 15495 p , Φ ST = 0 . 36501 p h = 0 . 913 , π = 0 . 97 % ) than in the Black Sea (D h = 0 . 732 , π = 0 . 30 % ) and three different genetic units were discovered based on significant Φ CT values (western Bay of Biscay, Villaviciosa (the easternmost locality sampled within the Bay of Biscay) and the Black Sea) ( Φ cT = 0 . 41076 p

Until the beginning of the 21st century, the famous medicinal leech was thought to be represented by only one species, Hirudo medicinalis. However, recent publications have demonstrated that under that name, at least five different species of medicinal leeches were hidden. During the last decade, the biogeography of Western-Palaearctic leeches has begun to unravel, untangling their diversity in practically all of Europe, except for its westernmost peninsula, Iberia. Hirudo medicinalis has been repeatedly reported from Iberia, but those records were considered questionable. We discovered H. verbana in northern Spain, constituting its first record in Iberia. Using an integrative approach (combining morpho-anatomical data and molecular analyses using three genes, COI,12S rRNA, and ITS2), two endemic and geographically separated Iberian lineages have been found. One of them is easily distinguished by its distinctive colour-pattern and is described as H. verbana bilineata ssp. nov. We ch...

Aim Evolutionary history of natural populations can be confounded by human intervention such as the case of decorator worm species Diopatra (Onuphidae), which have a history of being transported through anthropogenic activities. Because they build tubes and act as ecosystem engineers, they can have a large impact on the overall ecosystem in which they occur. One conspicuous member, Diopatra biscayensis, which was only described in 2012, has a fragmented distribution that includes the Bay of Biscay and the Normanno‐Breton Gulf in the English Channel. This study explores the origin of these worms in the Normanno‐Breton region, which has been debated to either be the result of a historic range contraction from a relic continuous population or a more recent introduction. Location Northeastern Atlantic, the Bay of Biscay, and the Normanno‐Breton Gulf. Methods We utilized a RAD‐tag‐based SNP approach to create a reduced genomic data set to recover fine‐scale population structure and infer...

The introduction of invasive species is considered one of the major threats to the biodiversity conservation worldwide. In recent years, an Asian invasive species of wasp has set off alarms in Europe and elsewhere in the world, Vespa velutina. The Asian wasp was accidentally introduced in France around 2004 and shortly thereafter it was able to colonise practically all of Europe, including the Iberian Peninsula. The ecological and economic implications of V. velutina invasion and its high colonisation ability have triggered widespread trapping campaigns, usually supported by beekeepers and local governments, with the aim of diminishing its population and its negative impacts. Among the most used control methods are the capture traps, which use a sugary attractant to catch the invasive wasps. However, the species-specific selectivity and efficiency of these traps has been little studied. In this paper, we have analysed the specific identity of the unintentionally trapped insect speci...

Here we report on the holothurian fauna at the Avilés Canyon System (Natura 2000 Site of Community Importance), central Cantabrian Sea, northern Spain. The samples were collected during several cruises covering the shelf, the continental slope and the abyssal depth. We identified 174 specimens, belonging to 35 species of the seven orders of class Holothuroidea. Depth was the main structuring agent. Multivariate analysis allowed the differentiation of four main assemblages which corresponded to abyssal plain, lower continental slope, upper continental slope, and continental shelf. Depth had a significant effect on holothurian species richness (it increased with depth at an approximate rate of 1.7 species 1000 m-1), which is consistent with previously described global patterns.

A new species of holothurian of the genus Psolus Oken, 1815 is described. Psolus rufus sp. nov. was found in the central Cantabrian slope (Bay of Biscay) at 1500 m depth. The new species is characterized by having: ovoid body, reddish colour in vivo; dorsal area enclosed in a complete test composed of imbricating scales; 10 triangular plates of the same size surrounding mouth; 10 oral tentacles; no dorsal papillae; tube feet in two rows in the ventrolateral radii but one single row in the medial third or the body; ossicles are big dorsal plates and small plates in the sole, which are smooth, irregular and perforated. The molecular study of the COI gene supports the morphological results, grouping P. rufus sp. nov. together with other members of the genus. However, the new species is genetically distinct from the two groups (Antarctic and Canadian) of the available sequenced Psolus species. Furthermore, a key to the Psolus species of the north-eastern Atlantic Ocean is provided.

Examination of the holotype of Paradiopatra bihanica (Intes & LeLoeuff, 1975) indicated that the identity of this species had been incorrectly represented in recent papers and that the ensuing synonymisation of P. calliopae Arvanitidis & Koukouras, 1997 was unwarranted. This led us to researching the history of the holotype and its representation in the literature to reinstate P. calliopae as the correct name for this very common Mediterranean and eastern North Atlantic species (Martínez & Adarraga 2001; Arias & Paxton 2015; Santelli et al. 2015).

Abstract A one-year study of the reproductive biology of a population of Diopatra neapolitana at Villaviciosa estuary, northern Spain, was undertaken. Field observations together with a histological study of monthly collected individuals revealed that the population was iteroparous, had a discontinuous reproductive season with a resting period during August and September and a spawning season from March to July. The study showed that D. neapolitana was not dioecious as previously suggested but consisted of protandric sequential hermaphrodites, pure males and pure females with a male biased sex ratio of 3:1. During the peak reproductive period from May to August we observed simultaneous hermaphrodites with two dorsal papillae per segment in the branchial region. Histological studies demonstrated that the papillae were acting as seminal vesicles, storing own sperm, and also as sperm ducts, providing an exit route; hence we termed them ‘spermaducal papillae’. The papillae are not the only sperm repositories as the coelom of males and simultaneous hermaphrodites in smaller size classes is also filled with sperm. The worms are broadcast spawners with a brief pelagic larval stage as previously reported but the finer points of this unusual fertilisation system need still to be elaborated. Diopatra cryptornata was recently described as a new species, supposedly differing from D. neapolitana in chaetal detail and the possession of the papillae. We have shown conclusively with morphological and genetical studies that the former species is a junior synonym of the latter. In the absence of type material we are here designating a neotype from recently collected material from Naples.

This work recognises five species of Paradiopatra from southwestern Europe, represented in the Bay of Biscay, the Atlantic coasts of Iberia and the western Mediterranean Sea. One species, Paradiopatra florencioi sp. nov., is newly described from the Cantabrian slope, northern Spain. We are presenting detailed diagnoses of all species and report ontogenetic changes of P. bihanica and P. hispanica. Scanning electron microscopy elucidated previously known Methylene Blue or Green staining patterns of the ventral glandular pads as cuticular pores. A dichotomous key to all species is included.

Abstract The polychaetous annelid Diopatra biscayensis Fauchald et al., 2012 was recently described from the Atlantic coast of France. It has been the subject of a plethora of publications dealing with its importance in the field of ecology: from its role as an ecosystem engineer, being an indicative species of climate change in western Europe to questions of whether it was native or introduced to the old continent, spawning theories about its hypothetical routes of introduction and spreading. We have redescribed D. biscayensis, traced its biogeographical history in the Bay of Biscay through examination of old museum holdings and studied its ecology and reproductive biology throughout a one year period from a northern Spain estuary, showing for the first time that the species is a protandric simultaneous hermaphrodite. The annual spawning season is from early August to late September, when large numbers of oocytes of 260 μm diameter were deposited in gelatinous egg masses attached to the parental tubes. Early trochophores developed in the jelly mass by 4–6 h, 3-chaetiger metatrochophores after 48 h, and the jelly mass had totally disintegrated by 72 h, releasing the lecithotrophic larvae. Our studies have clarified the morphology and reproductive pattern of D. biscayensis , documented that the species has inhabited the European waters for more than a century and we hope that these findings will serve as a basis to robust ecological studies and hypotheses concerning this and the related species.

Estuaries are among the most important habitats of coastal areas. However, they are significantly affected by human activities worldwide, threatening their resources and the commercial uses depending on them. Fisheries and aquaculture are some of the main factors affecting the estuarine ecosystems today. In this work, we pursue the aims of genetically identifying the cultured and harvested oyster and razor clam species inhabiting Asturian estuaries (Eo, Ribadesella and Villaviciosa) and describing the genetic diversity and patterns of genetic connectivity between those species in these estuaries. The results revealed the almost complete dominance of the introduced Crassostrea gigas as the species that supports the oyster's production in Asturias with a striking diversity of gene pools in wild environments (Ria de Villaviciosa and Ribadesella) which significantly exceeds the diversity found in the hatcheries seeds commonly used for culturing. Moreover, we detected two different species of Ensis sp. inhabiting the Asturian estuaries: Ensis ensis inside Ria del Eo and Ensis directus, an invasive species, in Ria de Villaviciosa. Significant genetic differentiation between estuaries for the exotic oyster C. gigas and also for the native razor clam Solen marginatus were found. These results suggest Asturian estuaries are not a single management unit for some species and thus prevention must be taken for avoiding intentional or human-mediated translocations among them. Biodiversity monitoring for discovering newcomer invasive species, measures for environmental recovery of these ecosystems and strict controls to avoid increasing of harvesting pressures are also a necessity to improve the management of these relevant ecosystems.

A new species of the genus Kuwaita Mohammad, 1973, collected intertidally from a northern Spain estuary (Bay of Biscay), is described. Kuwaita hanneloreae sp. nov. constitutes the first evidence of this genus in European waters and is characterised by: prostomium with three small antennae protruding from nuchal fold, lack of eyes; simple multidentate hooded hooks with long hood in anterior chaetigers, and short hood in posterior ones with well defined proximal and distal teeth with several teeth between them; posterior chaetigers with very small nephridial papillae; branchiae reduced to little knobs in posterior parapodia; maxillary apparatus with five pairs of maxillae, MIII bidentate with distal tooth bigger than proximal one. We present brief notes on its ecology and remarks on the presence and ultrastructure of a notopodial sense organ newly recorded for the genus. Furthermore, an updated key of the genus Kuwaita is included.

First observations on the reproductive biology of the alien polychaete Branchiomma bairdi (McIntosh, 1885) (Sabellidae) in the Mediterranean Sea are provided as well as additional Mediterranean records of the species which can help to understand its introduction and spreading. Re-examination of the specimens from Miseno harbour (Tyrrhenian Sea, Italy) revealed the presence of B. bairdi in the central-Mediterranean since September 2004. The histological study of individuals collected in Malta revealed that the species is a simultaneous hermaphrodite, developing male and female gametes in the same body segments; embryos are brooded inside the parent tube. However, there is evidence also for asexual reproduction. The species shows a different reproductive pattern from the previously reported population from the eastern-Pacific; this demonstrates its great plasticity and adaptability. Branchiomma bairdi has an invasive behaviour, colonizing large areas in relatively short-time, and reac...

Abstract We report on three species of deep-water onuphid polychaetes (Nothria maremontana, Paradiopatra hispanica and Rhamphobrachium brevibrachiatum) from the Bay of Biscay from depths of 468 to 1186 m. The three species contained eggs and/or juveniles inside the parental tubes and R. brevibrachiatum had a cocoon-like capsule attached on the outside of its tube containing fibres and sperm. We present brief taxonomic descriptions of the three species, including some observations on ontogenetic chaetal changes in N. maremontana. The brooded eggs ranged from 300 to 340 µm in diameter in N. maremontana, while R. brevibrachiatum eggs ranged from 390 to 450 µm; juveniles consisted of 6 chaetigers for N. maremontana and 6–45 chaetigers for P. hispanica. We describe and illustrate the eggs, juveniles and sperm capsule. Although the origin of the sperm capsule is questionable, we reject the possibility of an unrelated passenger and speculate that the structures contained inside the capsule are long, thin spermatophores of a type not previously known for onuphids.

A one-year study of the reproductive biology of a population of Diopatra marocensis at the Villaviciosa estuary, northern Spain, was undertaken with emphasis on brooding behaviour, larval development and gametogenesis. Field observations together with a histological study of monthly collected individuals revealed that the population was iteroparous, reproducing annually during a short breeding season extending from March to June. The study demonstrated that all individuals of the population at Villaviciosa estuary were producing at the same time eggs and sperm providing for the first time evidence for the occurrence of simultaneous hermaphroditism in D. marocensis. Mature sperm was of the ent-aquasperm type and was stored in modified nephridial chambers in brooding individuals. In the latter, eggs in advanced cleavage phases were also observed inside the coelom suggesting that fertilization was internal. Eggs in late vitellogenesis presented micronucleoli in the periphery of the nuc...

Land and freshwater molluscs are the most abundant non-arthropod invertebrates from inland habitats worldwide, playing important ecological roles and some being important pests in agriculture. However, despite their ecological, and even economic and sanitary importance, their local diversity in many European regions is not perfectly understood, with a particularly notableknowledge gap in the northern Iberian malacofauna. This work aims at providing a revised checklist of continental gastropods and bivalves from the Asturias (northern Spain), based on the examination of newly collected and deposited material and on the critical analysis of published and gray literature. A total of 165 molluscan species are recognized. Ten species constitute new records from Asturias and seven from northern Iberian Peninsula. Seventeen species are introduced or invasive, evidencing the current increase of the bioinvasion rate in continental molluscs. Furthermore, all these exotic species are parasite ...

Rhamphobrachium (Rhamphobrachium) agassizii is reported from the Cantabrian Sea, Spain, from depths of 925–1207 m. This is its first record off the Iberian Peninsula and in European waters, representing its northernmost distribution in the North Atlantic Ocean to date. Previous reports of R. (R.) agassizii from the eastern and western North Atlantic demonstrate its apparent amphi-Atlantic distribution, which appears consistent with the distribution of the main Atlantic currents. It is a typical deep-water species with its deepest record at 2165 m from the Azores archipelago. The specimens were collected singly at two stations, attesting to the rarity of the species in contrast to its congener R. (Spinigerium) brevibrachiatum which was the most dominant polychaete species in a previous study.

En el marco de un estudio de revisión de la malacofauna del Golfo de Vizcaya, se han
encontrado dos especies de gasterópodos pertenecientes a la familia Epitoniidae nuevas
para el Mar Cantábrico y para el Golfo de Vizcaya, Epitonium vittatum (Jeffreys, 1884)
y Epitonium fischeri (Watson, 1897), y otras dos probablemente aún no descritas y, por
tanto, nuevas para la ciencia. Hasta la fecha, solamente se han registrado 10 especies
de epitónidos para las costas Cantábricas. En este trabajo se consideran a E. fisheri y
E. vittatum como especies exóticas, no nativas del Golfo de Vizcaya. La primera es una
especie tropical de pequeño tamaño, extremadamente rara, que hasta ahora sólo había
sido citada para las islas macaronésicas de Madeira y Canarias. Se ha recolectado viva
sobre un antozoo colonial del que probablemente se alimenta. La segunda, E. vittatum,
posee un área de distribución que se extiende a lo largo de la costa occidental Africana
desde Costa de Marfil hasta el norte de Marruecos incluyendo el Mar de Alborán. La
presencia de estas dos especies exóticas en el Cantábrico es presumiblemente debida
al aumento de temperatura que se ha registrado en el Golfo de Vizcaya en las últimas
décadas y que ha podido favorecer que sus larvas planctotróficas hayan colonizado esta
zona gracias a las corrientes marinas. Por tanto, estamos ante un caso de expansión
hacia el norte de sus áreas de distribución, siendo actualmente el Golfo de Vizcaya su
límite de distribución más septentrional. En este estudio también se aportan datos sobre
la ecología de las cuatro especies, se indican los antozoos a los que aparecen asociados,
y se compara su anatomía y ecología con las de otros epitónidos de la Península Ibérica
de las que se tienen datos propios y también recopilados de revisiones bibliográficas.

Los eunícidos son un grupo gusanos poliquetos que habitan principalmente en mares
y océanos templado-cálidos, estando comúnmente asociados a sustratos rocosos
de la zona infralitoral. La familia Eunicidae es también una de las más grandes en
cuanto a número de especies, con un total de 250 especies pertenecientes a nueve
géneros reconocidos (Hartmann-Schröder & Zibrowius, 1998; Carrera-Parra, 2009).
En este trabajo, se presenta una revisión faunística actualizada de los eunícidos del
Mar Cantábrico. Los ejemplares fueron recolectados de la zona intermareal en varias
localidades desde el estuario de Foz (Galicia) hasta Bilbao (Euskadi), incluyendo Asturias
y Cantabria. También se revisaron los pertenecientes a las Campañas “COCACE”
recolectados en distintas estaciones a distintas profundidades entre 50 y 1.186 m.
Adicionalmente, se ha realizado una revisión bibliográfica de los eunícidos citados para
el Norte de España. Se han examinado un total de 142 ejemplares, identificándose
20 especies pertenecientes a 4 géneros (Eunice Cuvier, 1817; Marphysa Quatrefages,
1865; Lysidice Lamarck, 1818 y Nematonereis Schmarda, 1861). Dichas especies se
distribuyeron en tres grupos en función de la batimetría. Eunice resultó el género
mejor representado con 11 especies; de las cuales, E. torquata Quatrefages, 1866 fue
la más abundante en el intermareal rocoso y E. oerstedii Stimpson, 1853 y E. vitatta
(Delle Chiaje, 1828) en las muestras de profundidad. Marphysa sanguinea (Montagu,
1815) fue la más frecuente en los sustratos blandos costeros, siendo este género poco
abundante en fondos más profundos. Asimismo, Nematonereis y Lysidice estuvieron
representados por 1 y 4 especies respectivamente.

Los miembros de la familia Onuphidae (orden Eunicida) son en su mayoría gusanos
tubícolas que habitan principalmente en sustratos blandos y presentan una amplia
distribución mundial, pudiendo encontrarse en la mayoría de los grandes mares y océanos
desde la zona intermareal hasta las grandes profundidades marinas. Muchas especies
de esta familia, como Diopatra y Onuphis son organismos que definen los hábitats
mediante la creación de una estructura física o mediante la estructuración del flujo
de materiales (Jones et al., 1994). Por tanto, desde el punto de vista ecológico juegan
un papel muy importante estabilizando el sedimento e incrementando su complejidad
estructural gracias a la construcción de sus tubos, aumentando la biodiversidad del mismo
y facilitando la fijación y el desarrollo de diferentes especies de algas y otros organismos
sésiles (Thomsen y McGlathery, 2005; Arias et al., 2010). En este trabajo se recogen 15
especies de onúfidos procedentes tanto en la zona intermareal (muestreos de 2010-2011
en varias localidades de la costa Cantábrica desde el estuario de Foz hasta Bilbao) como
de distintas profundidades entre 50 m. y 1.200 m (campaña “COCACE”, 1976-1977).
Dichas especies se agrupan en 6 géneros (Aponuphis, Diopatra, Hyalinoecia, Nothria,
Paradiopatra y Rhamphobrachium), los cuales se disponen en 4 grupos distintos en
función de la batimetría; siendo Diopatra neapolitana Delle Chiaje, 1841 la especie más
abundante en aguas someras y Aponuphis bilineata (Baird, 1870) la más abundante
entre los 50 y los 300 m de profundidad. Así mismo, se analizan las características y
ornamentación de sus tubos mucosos, proponiéndose éste como un posible carácter
taxonómico para algunos géneros, como Diopatra. Finalmente se recogen dos especies,
Diopatra biscayensis (Fauchald et al., 2012) y Diopatra cryptornata (Fauchald et al.,
2012) que constituyen dos nuevas citas para el Cantábrico, siendo la primera, además,
un nuevo registro para la Península Ibérica.
