Effective monitoring of non-indigenous seaweeds and combatting their effects relies on a solid confirmation of the non-indigenous status of the respective species. We critically analysed the status of presumed non-indigenous seaweed species reported from the Mediterranean Sea, the Northeast Atlantic Ocean and Macaronesia, resulting in a list of 140 species whose non-indigenous nature is undisputed. For an additional 87 species it is unclear if they are native or non-indigenous (cryptogenic species) or their identity requires confirmation (data deficient species). We discuss the factors underlying both taxonomic and biogeographic uncertainties and outline recommendations to reduce uncertainty about the non-indigenous status of seaweeds. Our dataset consisted of over 19,000 distribution records, half of which can be attributed to only five species (Sargassum muticum, Bonnemaisonia hamifera, Asparagopsis armata, Caulerpa cylindracea and Colpomenia peregrina), while 56 species (40%) are recorded no more than once or twice. In addition, our analyses revealed considerable variation in the diversity of non-indigenous species between the geographic regions. The Eastern Mediterranean Sea is home to the largest fraction of non-indigenous seaweed species, the majority of which have a Red Sea or Indo-Pacific origin and have entered the Mediterranean Sea mostly via the Suez Canal. Non-indigenous seaweeds with native ranges situated in the Northwest Pacific make up a large fraction of the total in the Western Mediterranean Sea, Lusitania and Northern Europe, followed by non-indigenous species with a presumed Australasian origin. Uncertainty remains, however, regarding the native range of a substantial fraction of non-indigenous seaweeds in the study area. In so far as analyses of first detections can serve as a proxy for the introduction rate of non-indigenous seaweeds, these do not reveal a decrease in the introduction rate, indicating that the current measures and policies are insufficient to battle the introduction and spread of non-indigenous species in the study area. Non-indigenous seaweed species in the Northeast Atlantic Ocean, the Mediterranean Sea and Macaronesia are critically reanalysed. > 19,000 distribution records revealed considerable variation in diversity of non-indigenous seaweed species in the study area. Taxonomic and biogeographic uncertainties hamper a critical evaluation of the non-indigenous status of many seaweed species. [ABSTRACT FROM AUTHOR]

LAMINARIA ,KELPS ,FOREST declines ,MARINE algae ,SPATIAL arrangement ,SPRING - Abstract
Background and Aims Kelps are the primary foundation species in temperate subtidal rocky shores worldwide. However, global change is causing their decline with consequences for the organisms that rely on them. An accurate assessment of these consequences may depend on which attributes of the associated community are considered. This study shows that conventional α-diversity approaches may overlook some of these consequences compared to spatially explicit approaches such as with β-diversity. Methods A 1-year seasonal study was conducted to compare the macroalgal understorey between healthy reefs with a Laminaria ochroleuca canopy and degraded reefs where the canopy collapsed years ago due to excessive fish herbivory. At each reef, the understorey seaweed assemblage was recorded in five replicate quadrats to estimate α-diversity (total richness, species density, Shannon index) and β-diversity (intra- and inter-reef scale). Key Results The understorey assemblage exhibited a distinct seasonal dynamic in both healthy and degraded reefs. α-Diversity attributes increased in spring and summer; turf-forming algae were particularly dominant in degraded reefs during summer. β-Diversity also showed seasonal variability, but mostly due to the changes in degraded reefs. None of the α-diversity estimates differed significantly between healthy and degraded reefs. In contrast, spatial β-diversity was significantly lower in degraded reefs. Conclusions Although the loss of the kelp canopy affected the composition of the macroalgal understorey, none of the conventional indicators of α-diversity detected significant differences between healthy and degraded reefs. In contrast, small-scale spatial β-diversity decreased significantly as a result of deforestation, suggesting that the loss of kelp canopy may not significantly affect the number of species but still have an effect on their spatial arrangement. Our results suggest that small-scale β-diversity may be a good proxy for a more comprehensive assessment of the consequences of kelp forest decline. [ABSTRACT FROM AUTHOR]

- Abstract
[Abstract] Rhodolith seabeds are ‘ecosystem engineers’ composed of free-living calcareous red macroalgae, which create extensive marine habitats. This study addressed how depth influenced the structure (size and morphology) of rhodoliths and the abundance of associated floral and faunal epibionts across the Eastern Atlantic Ocean. Sampling was carried out at two sites within five regions (Brittany, Galicia, Madeira, Gran Canaria, and Principe Island), from temperate to tropical, covering a latitudinal gradient of 47°, in three depth strata (shallow, intermediate and deep), according to the rhodolith bathymetrical range in each region. Depth typically affected the rhodolith size at all regions; the largest nodules were found in the intermediate and deep strata, while rhodolith sphericity was larger at the shallow depth strata. Higher biomasses of attached macroalgae (epiphytes) were observed at depths where rhodoliths were larger. The abundance of epifauna was variable across regions and depth strata. In general, the occurrence, structure, and abundance of the associated biota across rhodolith habitats were affected by depth, with local variability (i.e., sites within regions) often displaying a more significant influence than the regional (large-scale) variation. Overall, this study showed that the rhodolith morphology and associated epibionts (flora and fauna) were mostly affected by depth, irrespective of latitude.

- Abstract
The analysis of biological and ecological traits has a long history in evolutionary and ecological research. However, trait data are often scattered and standardised terminology that transcends taxonomic and biogeographical context are generally missing. As part of the development of a global trait database of marine species, we collated trait information for European seaweeds and structured the data within the standardised framework of the World Register of Marine Species (WoRMS). We collected 45175 trait records for 21 biologically and ecologically relevant traits of seaweeds. This resulted in a trait database for 1745 European seaweed species of which more than half (56%) of the records were documented at the species level, while the remaining 44% were documented at a higher taxonomic level and subsequently inherited at lower levels. The trait database for European seaweeds will serve as a foundation for future research on diversity and evolution of seaweeds and their responses to global changes. The data will contribute to developing detailed trait-based ecosystem models and will be an important tool to inform marine conservation policies. The data are publicly accessible through the AlgaeTraits portal, 10.14284/574 (AlgaeTraits, 2022).

- Abstract
[Abstract] The present Doctoral Thesis aimed to provide a detailed study about the flora of coralline red algae in NW Iberian Peninsula through the compilation of existing data and new information generated in the present study. The review of literature was combined with examination of herbarium material and the study of new samples. The survey of 74 localities located in six provinces of Galicia and northern Portugal provided 1300 specimens, housed at the herbarium SANT. The catalogue encompassed 14 genera and 46 species. For each species, a description and illustrations are provided, apart from information about habitat and distribution in the study area. An identification key for the 46 species recorded is also provided. Nine species are new records for the NW Atlantic Iberian, such as Harveylithon samoënse, Hydrolithon boreale and Pneophyllum coronatum. Moreover, it is provided 40 new province records for 16 species. Morphological variations were also reported in Jania longifurca, J. rubens, Phymatolithon lamii and P. lenormandii. In addition, molecular and morphological results detected cryptic species of Lithophyllum, Lithothamnion Phymatolithon and Mesophyllum. Finally, two species (Lithophyllum duckerae, Phymatolithon purpureum) were deleted of NW Iberia Peninsula, and six ones (Boreolithon van-heurckii, Hydrolithon farinosum, Lithophyllum vickersiae, Leptophytum bisporum, Lithothamnion sonderi, Titanoderma cystoseirae) were considered as doubtful., [Resumen] Esta tesis pretende aportar un estudio detallado de la diversidad de algas rojas coralinas del noroeste ibérico, mediante la integración de información de especies conocidas con nuevos datos obtenidos del trabajo experimental.

- Abstract
[EN] Syngnathid fishes (Actinopterygii, Syngnathidae), including seahorses and pipefishes, are flagship vulnerable species highly associated with seaweed and seagrass habitats. Our multidisciplinary study provides the first insights for syngnathid populations in Atlantic Islands of Galicia (Cíes Archipelago, Atlantic Ocean) and Cabrera Archipelago (Mediterranean Sea) Spanish National Parks. Syngnathid fishes were collected on several sites in the first year of the study, and habitat characteristics were also determined. From the results achieved, a further two-years monitoring was performed seasonally in selected sites. The fishes were analyzed for size, weight, sex and sexual maturity, stable isotope signatures and genetics. Epifauna and gut contents were also analyzed for further dietary assessment of syngnathids. Diversity and abundances were generally low, with four species (including seahorses) identified in the Atlantic Islands of Galicia National Park and five (only pipefishes) at Cabrera National Park. Syngnathids from both national parks differed in size, isotopic values and prey regime. Syngnathids preferred less exposed sites in macroalgal assemblages (Atlantic) or Cymodocea meadows (Mediterranean). Population characteristics in the Atlantic Islands of Galicia National Park suggests that syngnathids mainly comprise breeders that migrate seasonally, with preference for less exposed sites on shallow complex rocky-sandy substrates covered by macroalgae. Prey preferences would rely mainly on the consumption of copepods and gammarids. In the Mediterranean, syngnathids were likely limited by the depth of the studied sites, showing preference for Cymodocea meadows over Posidonia, and for the capture of a wider range of prey compared to the Atlantic populations. Borrón (Atlantic) and Es Burri (Mediterranean) would be preferential sites to undertake conservations plans for syngnathids.

39 pages, [EN] Syngnathid fishes (Actinopterygii, Syngnathidae), including seahorses and pipefishes, are flagship vulnerable species highly associated with seaweed and seagrass habitats. Our multidisciplinary study provides the first insights for syngnathid populations in Atlantic Islands of Galicia (Cíes Archipelago, Atlantic Ocean) and Cabrera Archipelago (Mediterranean Sea) Spanish National Parks. Syngnathid fishes were collected on several sites in the first year of the study, and habitat characteristics were also determined. From the results achieved, a further two-years monitoring was performed seasonally in selected sites. The fishes were analyzed for size, weight, sex and sexual maturity, stable isotope signatures and genetics. Epifauna and gut contents were also analyzed for further dietary assessment of syngnathids. Diversity and abundances were generally low, with four species (including seahorses) identified in the Atlantic Islands of Galicia National Park and five (only pipefishes) at Cabrera National Park. Syngnathids from both national parks differed in size, isotopic values and prey regime. Syngnathids preferred less exposed sites in macroalgal assemblages (Atlantic) or Cymodocea meadows (Mediterranean). Population characteristics in the Atlantic Islands of Galicia National Park suggests that syngnathids mainly comprise breeders that migrate seasonally, with preference for less exposed sites on shallow complex rocky-sandy substrates covered by macroalgae.

The analysis of biological and ecological traits has a long history in evolutionary and ecological research. However, trait data are often scattered and standardised terminology that transcends taxonomic and biogeographical context are generally missing. As part of the development of a global trait database of marine species, we collated trait information for European seaweeds and structured the data within the standardised framework of the World Register of Marine Species (WoRMS). We collected 45,175 records for 21 biologically and ecologically relevant traits of seaweeds. This resulted in a trait database for 1,745 European seaweed species of which more than half (56%) of the records were documented at the species level, while the remaining 44% was documented at a higher taxonomic level and subsequently inherited at lower levels. The trait database for European seaweeds will serve as a foundation for future research on diversity and evolution of seaweeds, and their responses to global changes. The data will contribute to developing detailed trait-based ecosystem models, and will be an important tool to inform marine conservation policies. The data is publicly accessible through the AlgaeTraits portal, algaetraits.org, doi: https://doi.org/10.14284/574, (AlgaeTraits, 2022). [ABSTRACT FROM AUTHOR]

- Abstract
Hace más de 50 años comenzó su andadura el Centro Oceanográfico de A Coruña. Ocurrió en un vetusto local del puerto, y se denominó por aquel entonces como Laboratorio del Noroeste. Durante este medio siglo este centro ha trabajado básicamente en las áreas de la biología pesquera, la acuicultura marina y la oceanografía multidisciplinar, si bien los equipos de investigación han ido evolucionando a lo largo de este tiempo, abriendo o cerrando líneas de trabajo según las circunstancias. A pesar de haber trabajado en todos los océanos del mundo, incluidos el ártico y el antártico, una parte importante de las investigaciones del oceanográfico coruñés siempre han estado centradas en su entorno cercano: el golfo Ártabro. Desde los años ochenta, este centro coruñés monitorea el ambiente pelágico y bentónico de la ría de A Coruña y su plataforma adyacente. Esto supone una valiosísima serie histórica de datos oceanográficos, cuya utilidad quedó de sobra demostrada durante las catástrofes de los petroleros Aegean Sea y Prestige. La idea de crear este libro surgió justo antes del 50 Aniversario del Centro Oceanográfico de A Coruña (1968-2018). Nace con la intención de recopilar y resumir el conocimiento científico en torno a la biodiversidad marina en el ámbito de trabajo más cercano al centro coruñés. Es intención de este libro el servir como publicación de referencia a todo tipo de estudio sobre la biodiversidad y la oceanografía biológica del golfo Ártabro. Para ello nos servimos de la información obtenida directamente del oceanográfico herculino tanto de sus series históricas, como de otros estudios realizados en la zona. Además, la colaboración en materia de pesca de los centros oceanográficos de A Coruña, Vigo, Santander y Gijón permitió aportar a este volumen el capítulo dedicado a las especies desembarcadas por la flota artesanal en la lonja coruñesa. Por otra parte, los especialistas en bentos duro del Centro de Gijón fueron los encargados de elaborar la parte dedicada

[Resumen] En los fondos de maerl de Galicia se detectó material de Jania J.V.Lamour. con una morfología distinta de la típica atribuida a J. longifurca Zanardini y J. rubens (L.) J.V.Lamour. —únicas especies citadas en este hábitat en Galicia—. Esta consiste en: intergenículos delgados, ramificación dicotómica irregular y discos secundarios que facilitan la refijación al substrato, caracteres congruentes con los de otras especies de Jania de distribución más meridional. No obstante, el estudio taxonómico integrador de este material y de otras recolecciones de hábitat rocoso confirmó su identificación como J. longifurca. Así, la morfología atípica con intergenículos delgados y discos secundarios de fijación es dominante en ejemplares de J. longifurca procedentes de fondos de maerl, mientras que los ejemplares de ambientes rocosos presentan los típicos intergenículos robustos. Por otra parte, análisis moleculares detectaron cierta afinidad filogenética de J. longifurca con ejemplares de Nueva Zelanda, donde esta especie no está citada. Se concluye entonces que la variación morfológica en J. longifurca está relacionada con el ambiente y se evidencia la necesidad de estudios moleculares para esclarecer la taxonomía de este género, que está basada fundamentalmente en caracteres morfológicos. [Abstract] Material of Jania J.V.Lamour. with a different morphology from the typical one attributed to J. longifurca Zanardini and J. rubens (L.) J.V.Lamour.—the only species in this habitat in Galicia—has been detected in the maerl beds of Galicia. This morphology consists on: thin intergenicula, an irregular pattern of dichotomies and secondary attachment discs that facilitate the refixation to the substrate, all of them similar to those of other southern species of Jania. Nevertheless, the integrative taxonomic study of this material and other collections from rocky habitat confirmed its identification as J. longifurca. Thereby, the atypical morphology with thin intergenicula and secondary attachment disc is dominant in samples of J. longifurca from maerl beds, while the samples from rocky environments showed the typical robust intergenicula. Moreover, molecular analysis resolved some phylogenetic affinities with samples from New Zealand, where this species is not recorded. It is concluded therefore the morphological variation related to the environment and it is evident the need of molecular studies to clarify this genus taxonomy, which is based fundamentally on morphological characters.

- Abstract
Canopy-forming seaweeds sustain critical ecosystem services in coastal habitats. Around the world, many of these seaweeds are suffering strong declines, mainly attributed to the progressive increase in sea surface temperature, in combination with other stressors due to current global changes. The southernmost part of the NE Atlantic is among those areas most affected by climate change. In this study, we estimated the distributional contractions of seven of the most conspicuous seaweeds from the Atlantic coasts of the Iberian Peninsula using an “Extent of Occurrence” methodology. Overall, during the last three decades, range shifts have been more pronounced east of the Cantabrian Sea than along the western coast of the Iberian Peninsula. In particular, regions with a semi-permanent summer upwelling seem to be critical to the persistence of brown seaweeds, fucoids and kelps. Range contractions of the cold-temperate fucoids were estimated to be ca. 21% and 45% for Himanthalia elongata and Fucus serratus, respectively; and for the kelps Saccharina latissima and Laminaria hyperborea, 6% and 14%, respectively. Range contractions for warm-temperate kelps were estimated to be ca. 13% and 10% for Saccorhiza polyschides and L. ochroleuca, respectively. Finally, a decline in the warm-temperate red algae Gelidium corneum occurred only in the easternmost area of the Cantabrian Sea (Basque Country), leading to a distributional contraction of 7%. We recommend conservation actions to better manage the remnant populations of these canopy-forming seaweeds, and their inclusion in national and regional catalogues of endangered species and on international Red Lists.

Continuando con los estudios para la actualización del inventariado de la flora bentónica marina del Atlántico Ibérico. En este trabajo se incluye nueva información de distribución para 18 especies (3 Cyanobacteria, 9 Rhodophyta, 4 Ochrophyta, 2 Chlorophyta) de algas bentónicas marinas, recolectadas en el intermareal y submareal de 46 localidades del atlántico ibérico norte. Atendiendo a la distribución de las especies recolectadas, cabe destacar una nueva cita para Europa (Plocamium cf. ovicorne), 3 nuevas citas para Galicia (Calothrix consociata, Lyngbya martensiana y Centroceras gasparrinii), 14 nuevas citas provinciales y 8 segundas citas provinciales. Además dos especies (Spermothamnion strictum y Punctaria plantaginea) son excluidas de la flora de Galicia después, de estudiar el único material de herbario testigo de las citas.et al. 2005a-b, 2006, 2008, 2012, 2014, 2015, 2016), se presentan nuevas citas y correcciones florísticas que completan el actual inventario de la biodiversidad marina de Galicia (Bañón 2017). La mayoría de las muestras se conservaron en formalina al 4% y la conservación definitiva se realizó en pliegos de herbario, depositados en el herbario de la Universidad de Santiago de Compostela (SANT), así como en preparaciones semipermanentes en Karo®. También se estudiaron pliegos de herbario del Nationaal Herbarium Nederland, para la verificación o corrección de citas antiguas. Paralelamente, se conservaron fragmentos sin formolar de algunas especies en gel de sílice para estudios moleculares.

- Abstract
The composition, abundance, and distribution of epiphytic macroalgae living in meadows of Zostera marina L. in the northwestern Iberian Peninsula are here analyzed. We identified 63 species: 40 red algae, 16 brown algae, and 7 green algae. Most of them are classified as filamentous or filiform functional forms, while Pneophyllum fragile Kütz. was the only encrusting species. In general, the surface covered by epiphytes on the leaves of Zostera marina was low and a 43% of species were only found in juvenile stages. Regarding their frequency, 10 species were collected in the majority of the areas, while others were rare. Most species were found both epiphytic and in other substrata of the meadows, but 9 were exclusively epiphytic. We detected 9 introduced species., Se han analizado la composición, la abundancia y la distribución de macroalgas epifitas que viven en praderas de Zostera marina L. del noroeste de la península ibérica. Se han identificado 63 especies: 40 algas rojas, 16 pardas y 7 verdes. La mayoría pertenecen a los grupos funcionales filamentosos o filiformes, excepto Pneophyllum fragile Kütz., la única especie costrosa. En general, la cobertura de epifitos en las hojas de Zostera marina fue baja y un 43% de las especies solo se encontraron como estadios juveniles. En cuanto a su frecuencia, 10 de ellas se recolectaron en la mayoría de las áreas, mientras que el resto fueron más raras. La mayor parte de las especies se encontraron tanto epifitas como en otros substratos de las praderas, si bien 9 resultaron exclusivamente epifitas. Detectamos 9 especies introducidas.

This morphology consists on: thin intergenicula, an irregular pattern of dichotomies and secondary attachment discs that facilitate the refixation to the substrate, all of them similar to those of other southern species of Jania. Nevertheless, the integrative taxonomic study of this material and other collections from rocky habitat confirmed its identification as J. longifurca. Thereby, the atypical morphology with thin intergenicula and secondary attachment disc is dominant in samples of J. longifurca from maerl beds, while the samples from rocky environments showed the typical robust intergenicula. Moreover, molecular analysis resolved some phylogenetic affinities with samples from New Zealand, where this species is not recorded. It is concluded therefore the morphological variation related to the environment and it is evident the need of molecular studies to clarify this genus taxonomy, which is based fundamentally on morphological characters., En los fondos de maerl de Galicia se detectó material de Jania J.V.Lamour. con una morfología distinta de la típica atribuida a J. longifurca Zanardini y J. rubens (L.) J.V.Lamour. —únicas especies citadas en este hábitat en Galicia—. Esta consiste en: intergenículos delgados, ramificación dicotómica irregular y discos secundarios que facilitan la refijación al substrato, caracteres congruentes con los de otras especies de Jania de distribución más meridional. No obstante, el estudio taxonómico integrador de este material y de otras recolecciones de hábitat rocoso confirmó su identificación como J. longifurca. Así, la morfología atípica con intergenículos delgados y discos secundarios de fijación es dominante en ejemplares de J. longifurca procedentes de fondos de maerl, mientras que los ejemplares de ambientes rocosos presentan los típicos intergenículos robustos. Por otra parte, análisis moleculares detectaron cierta afinidad filogenética de J. longifurca con ejemplares de Nueva Zelanda, donde esta especie no está citada. Se concluye entonces que la variación morfológica en J. longifurca está relacionada con el ambiente y se evidencia la necesidad de estudios moleculares para esclarecer la taxonomía de este género, que está basada fundamentalmente en caracteres morfológicos.

- Abstract
[Abstract] The composition, abundance, and distribution of epiphytic macroalgae living in meadows of Zostera marina L. in the northwestern Iberian Peninsula are here analyzed. We identified 63 species: 40 red algae, 16 brown algae, and 7 green algae. Most of them are classified as filamentous or filiform functional forms, while Pneophyllum fragile Kütz. was the only encrusting species. In general, the surface covered by epiphytes on the leaves of Zostera marina was low and a 43% of species were only found in juvenile stages. Regarding their frequency, 10 species were collected in the majority of the areas, while others were rare. Most species were found both epiphytic and in other substrata of the meadows, but 9 were exclusively epiphytic. We detected 9 introduced species., [Resumen] Se han analizado la composición, la abundancia y la distribución de macroalgas epifitas que viven en praderas de Zostera marina L. del noroeste de la península ibérica. Se han identificado 63 especies: 40 algas rojas, 16 pardas y 7 verdes. La mayoría pertenecen a los grupos funcionales filamentosos o filiformes, excepto Pneophyllum fragile Kütz., la única especie costrosa. En general, la cobertura de epifitos en las hojas de Zostera marina fue baja y un 43% de las especies solo se encontraron como estadios juveniles. En cuanto a su frecuencia, 10 de ellas se recolectaron en la mayoría de las áreas, mientras que el resto fueron más raras. La mayor parte de las especies se encontraron tanto epifitas como en otros substratos de las praderas, si bien 9 resultaron exclusivamente epifitas. Detectamos 9 especies introducidas.

- Abstract
DNA barcoding in combination with morpho-anatomical analysis was applied to study the diversity of crustose coralline algae associated to two maerl beds from two protected Atlantic European areas from Brittany and Galicia —France and Spain, respectively—. Given the records of gametophytes of the maerl species Phymatolithon calcareum under crustose growth-forms, and that associated crustose coralline algae appear to be involved in the recruitment of new maerl plants, we compared the species composition between the associated crustose coralline algae to Breton and Galician maerl beds with the maerl species identified in these beds in previous DNA barcoding surveys. Our molecular results revealed higher species diversity in associated crustose coralline algae than in maerl-forming species. Nine taxa of crustose coralline algae were found in both study areas: four in Brittany and five in Galicia. Three species from Brittany were identified as Phymatolithon calcareum, Phymatolithon lamii, and Lithophyllum hibernicum. The remaining six ones were assigned to the genera Phymatolithon and Mesophyllum, along with Lithothamnion and Lithophyllum. Morpho-anatomical examination of diagnostic characters corroborated our molecular identification. Our results showed that the most representative genus of crustose coralline algae in Brittany was Phymatolithon, while in Galicia was Mesophyllum. In Brittany, Phymatolithon calcareum was found under both growth-forms, maerl and crustose coralline algae, the latter assigned to the gametophyte stage by the presence of uniporate conceptacles. The recruitment of new maerl plants involving associated crustose coralline algae with maerl beds may occur, but only we can affirm it for Phymatolithon calcareum in Brittany. By contrast, the different species composition between both growth-forms in the Galician maerl beds would indicate that the fragmentation of own free-living maerl species appears to be the most common propagation mechanism, En este trabajo se han utilizado el sistema de códigos de barras genéticos y análisis morfo-anatómicos para estudiar la diversidad de algas coralinas costrosas asociadas a dos fondos de maerl localizados en dos áreas protegidas del Atlántico Europeo en Bretaña y Galicia —Francia and España, respectivamente—. Dadas las citas recientes de gametófitos de la especie típica de lechos de maerl, Phymatolithon calcareum, bajo una forma de crecimiento costrosa, y que las algas coralinas incrustantes parecen estar implicadas en el reclutamiento de nuevas plantas del maerl, en este trabajo se compara la composición entre estas algas asociadas a fondos de maerl bretones y gallegos, con las especies del maerl identificadas en estos fondos en estudios previos de códigos de barras genéticos. Los resultados moleculares del presente trabajo revelaron una diversidad más alta en las algas coralinas costrosas asociadas que en las propias especies formadoras del maerl. En las áreas estudiadas se encontraron nueve táxones de algas coralinas costrosas: cuatro en la Bretaña francesa y cinco en Galicia. Tres especies de la Bretaña fueron identificadas como Phymatolithon calcareum, Phymatolithon lamii y Lithophyllum hibernicum. Las seis especies restantes fueron asignadas a los géneros Phymatolithon y Mesophyllum, junto con Lithothamnion y Lithophyllum. El examen morfo-anatómico de caracteres diagnósticos concordó con la identificación molecular. Los resultados obtenidos evidenciaron que el género más representativo de algas coralinas costrosas en la Bretaña fue Phymatolithon, mientras que en Galicia fue Mesophyllum. En la Bretaña, Phymatolithon calcareum fue encontrado bajo ambas formas de crecimiento —maerl y morfología incrustante—, en este último caso asignada a la generación gametofítica por la presencia de conceptáculos uniporados. El reclutamiento de nuevas plantas del maerl a través de las algas coralinas costrosas asociadas a fondos de maerl puede suceder, pero solo se puede afirmar

- Abstract
[Resumen:] Las especies invasoras pueden tener graves efectos negativos sobre los ecosistemas, siendo la segunda causa de pérdida de biodiversidad a nivel mundial. El mar Mediterráneo es uno de los mares más afectado por la invasión de especies foráneas debido a sus comunicaciones con el Atlántico mediante el estrecho de Gibraltar y con el mar Rojo mediante el canal de Suez y al intenso tráfico marítimo que en sus aguas ocurre. Una de las especies invasoras es el alga Halimeda incrassata que fue por primera vez localizada en el Mediterráneo (en aguas de Baleares) en 2011, es un alga de origen tropical que podría haber sido introducida mediante su uso en acuariofilia, turismo náutico o transporte marino. El área marina protegida de la Bahía de Palma en concreto el Cap Enderrocat ha sufrido una gran proliferación de esta alga en sus arenales desde su detección en 2011 y el objetivo de este trabajo es estudiar las comunidades de invertebrados que en esta localidad habitan, y testar un nuevo método de muestreo para epifauna. Para ello, se diseñó un experimento en el que se capturaron macroinvertebrados en 3 hábitats diferentes: banco de arena, pradera de Halimeda incrassata y pradera mixta de Cymodocea nodosa con Halimeda incrassata, mediante tres métodos diferentes. Los resultados muestran que la abundancia de los taxones estudiados es mayor tanto en la pradera mixta como en la de la Halimeda incrassata y por lo tanto se puede decir que la invasión tiene un efecto positivo para la abundancia de los siguientes grupos: Amphipoda, Isópoda, Cumacea, Mysidacea, Natantia, larvas Zoea y Ostracoda. Es decir, la invasión de H. incrassata en esta zona ha podido provocar un aumento de la biomasa de estos grupos de mesofauna, presas potenciales de peces que habitan en la zona como salmonetes pageles y raones, pudiendo provocar un efecto positivo para dichas especies. Al crear un nuevo hábitat antes inexistente (sobre fondo de arena), esta especie contribuye a escala local al aumen, [Abstract:] Invasive species can have serious negative effects on ecosystems, being the second leading cause of biodiversity loss worldwide. The Mediterranean Sea is one of the most affected seas by the invasion of alien species due to the communications with the Atlantic by the Strait of Gibraltar, the Red Sea by the Suez cannel and the long history of boating. One of invasive species is Halimeda incrassata which was first reported in the Mediterranean (Balearic waters) in 2011. This is a tropical alga which was likely introduced via the aquarium trade or marine transport. The marine protected area of the bay of Palma, specifically Cap Enderrocat has suffered a great proliferation of this alga and the main objective of this work is to examine the invertebrates communities in this area and assess different sampling methodologies. A comparative sampling approached was designed to capture macroinvertebrates from 3 different habitats: sandy bottom, Halimeda incrassata beds and beds of Cymodocea nodosa mixed with Halimeda incrassata using three diferent methods. The results show that the abundance of the studied taxa is greater in the mixed habitat and in the one of the Halimeda incrassata and therefore it can be said that the invasion has a positive effect for the abundance of the following groups: Amphipoda, Isópoda, Cumacea, Mysidacea, Natantia, Zoea and Ostracoda larvae. That allows to say that the invasion of H. incrassata has been able to promote an increase of the biomass of these groups of mesofauna, potential prey of fish that inhabit the area as razor fish and another labrids, being able to provoke a positive effect for these species. By creating a new habitat previously non-existent (on sandy bottom), this invasive species contributes locally to increased diversity and biomass of invertebrates. However, since this is a first work done, it should be complemented in the future by increasing the spatial scale of the study, incorporating the study of temporal cha

The Iberian Peninsula contains 24 specific and infraespecific taxa of the genus Cystoseira, but only 6 inhabit in Northern Iberia: C. baccata, C. foeniculacea, C. humilis var. myriophylloides, C. nodicaulis, C. tamariscifolia, and C. usneoides. The Cystoseira assemblages exhibit a complex structure and stratification that allows the presence of a large associate biota and a rich epiphytic flora. Although in the Mediterranean Sea several species have been analyzed in depth, the Atlantic ones are less studied. A revision of the literature (1931-2014) and grey information was made to know the diversity of the North Atlantic Iberian Cystoseira assemblages. The community of C. baccata harbors the biggest number of species (215), followed by C. tamariscifolia (162) and C. usneoides (126), whereas the community with fewest species was the C. foeniculacea one (34). More than 70 species were present in the majority of the Cystoseira assemblages. In this article, are revised also environmental issues in the Cystoseira assemblages, as pollution and anthropogenic pressures or disturbances that cause regression in their communities, and effects of biological invasions by non-native species. As a conclusion, it will necessary to study the Cystoseira assemblage in depth, starting by research of C. baccata along Northern Iberia, as it is an exclusive and widely distributed Atlantic species with very scarce information concerning its role in structuring the communities.La Península Ibérica contiene 24 táxones del género Cystoseira, pero sólo 6 habitan en las costas del norte: C. baccata, C. foeniculacea, C. humilis var. myriophylloides, C. nodicaulis, C. tamariscifolia y C. usneoides. Las comunidades de Cystoseira muestran una estructura compleja debido a su estratificación, lo que permite el desarrollo de una amplia biota asociada y una gran riqueza de flora epífita. Aunque diversas especies mediterráneas han sido analizadas en profundidad, las atlánticas son menos conocidas. Se ha recopilado información bibliográfica (1931-2014) y datos inéditos para conocer la diversidad de las comunidades de Cystoseira en las costas atlánticas del norte de la Península Ibérica. Las comunidades de C. baccata albergan el mayor número de especies (215), seguido de C. tamariscifolia (162) y C. usneoides (126), mientras que la comunidad con el menor número de especies fue C. foeniculacea (34). Más de 70 especies están presentes en la mayoría de las comunidades de Cystoseira. En este artículo, se han revisado también aspectos medioambientales que afectan a las comunidades de Cystoseira, como contaminación y perturbaciones antropogénicas que causan la regresión de las poblaciones, así como los efectos de las invasiones biológicas por especies alóctonas. Como conclusión, será necesario el estudio de las comunidades de Cystoseira en profundidad, empezando por investigaciones de C. baccata en el norte, ya que es una especie exclusiva y ampliamente distribuida en el Atlántico y con escasa información relativa a su papel en la estructuración de comunidades.
