We have followed the recovery of gaps produced either by harvesters or by scientists in stands of stalked barnacle (Pollicipes pollicipes) during two years in four regions of Europe (SW Portugal, Galicia and Asturias in Spain and Brittany in France; n = 423 gaps), which was extended to four years in Asturias (n = 252 gaps). The presence of adult co...
The unceasing rise in human population has provoked large environmental damage, essentially in air and water habitats. Microalgae have been deeply investigated regarding wastewater treatment as well as a suitable biofuel feedstock. Nevertheless, process optimization and the search for new local strains are imperative to overcome the cost-effectiven...

The trend towards an increased incidence of marine heatwaves (MHWs) due to climate change poses a serious threat to the health of coastal ecosystems. Here, we characterized MHWs based on daily in situ water temperature measurements collected from 1998 to 2019 in two intertidal coves, Oleiros and La Franca, located in the central Cantabrian Sea coas...
The exploitation of Gelidium corneum (Hudson) J.V. Lamouroux in the Cantabrian Sea has an important economic and cultural component. Through the extraction methods of hand plucking underwater and collection of cast seaweed, this seaweed contributes to the livelihoods of many individuals within the region. This species is an international commodity...
Analyses of long-term temperature records based on satellite data have revealed an increase in the frequency and intensity of marine heatwaves (MHWs) in the world oceans, a trend directly associated with global change according to climate model simulations. However, these analyses often target open ocean pelagic systems and rarely include local sca...
Several international organisations have recommended the use of bioindicators to improve the evaluation of ecological risk in marine ecosystems. In this context, wild mussels, a recognised bioindicator, were collected from thirty sampling points along the Asturias coastline and studied in order to identify any relationship between metal(oid) concen...
In January 2020, a stakeholder workshop was organized as a knowledge sharing strategy among European stalked barnacle fisheries. Management of this fishery differs greatly among regions and ranges from less organized and governed at large scales (>100 km, coasts of SW Portugal and Brittany in France) to highly participatory systems which are co-man...
Derived from their great capacity of adaptation, microalgae have several industrial applications, including pigment production for nutraceutical sector. However, the scarcity of studies on the diversity and life histories from several environments, highlight the need for more research on new species and habitats. Based on this, the present study as...
In this work, we identified non-crustose invasive (Codium fragile subsp. fragile) and native Codium spp. (Codium tomentosum and Codium vermilara) in the central Cantabrian Sea using DNA barcoding (tufA and rbcL genes). We designed a new FCOtufA genetic marker for identifying Codium spp. in fresh and herbarium material. The tufA and rbcL sequences r...
Invasive species threaten worldwide biodiversity. Success in facing this problem may be possible through the engagement of younger audiences. Here, a game was designed to teach children how to recognize invasive seaweed and to encourage them to participate in marine citizen science. The game was first tested in a pilot study, and then carried out i...
The PERCEBES project aspires to answer questions regarding the effects of harvesting on the intertidal community and recovery potential of stalked barnacle populations after harvesting, for which a Human Exclusion Experiment has been deployed over 2 years in 4 regions: coast of Alentejo (Portugal), Atlantic Islands (Galicia, Spain), Western Asturia...
Aim:
Codium fragile, an invasive seaweed, has spread widely during the last century, impacting on local seaweed communities through competition and disturbance. Early detection of C. fragile can help on its control and management. Environmental DNA (eDNA) has proved successful for early detection of aquatic invasive species but its potential use f...
This study has been carried out on the Nalón estuary, a mining impacted estuarine contaminated by metals(oid), to evaluate how the metals(oids) concentrations in the sediments contributes to the toxicity and, therefore, supposes a potential risk for the biota. For this purpose, a total of 14 surface sediment samples were collected and analysed by d...

Background
The introduction of exotic species can have serious consequences for marine ecosystems. On the shores of the Cantabrian Sea (North of Spain) there are no routine examinations of seaweeds that combine molecular and morphological methods for early detection of exotic species making it difficult to assess in the early stages their establish...
The agarophyte family Gelidiellaceae currently includes 26 species in two genera, Gelidiella and Parviphycus, but the generic status and species boundaries have not been fully explored. In order to resolve taxonomic issues in the family, we analyzed mitochondria-encoded cox1 and plastid-encoded rbcL and psaA genes from types and fresh collections i...
A comprehensive expert consultation was conducted in order to assess the status, trends and the most important drivers of change in the abundance and geographical distribution of kelp forests in European waters. This consultation included an on-line questionnaire, results from a workshop and data provided by a selected group of experts working on k...
Introduction of nonindigenous species (NIS) via anthropogenic activities (i.e. shipping) has serious consequences for marine ecosystems. On shores of the Cantabrian Sea (northern Spain), there is no routine NIS screening combining molecular and anatomical methods. This makes the detection of inadvertent expansions of exotic species difficult. In th...
Members of the Streptomyces albidoflavus clade, identified by 16S rRNA sequencing and phylogenetic analyses, are widespread among predominant terrestrial lichens (Flavoparmelia caperata and Xanthoria parietina) and diverse intertidal and subtidal marine macroalgae, brown red and green (Phylum Heterokontophyta, Rhodophyta, and Chlorophyta) from the...

The existing literature on phototropism in marine macroalgae is reviewed. A phototropic response is a sequence of three different processes: reception of the directional light signal; transformation of the signal to a physiological response (transduction); and the production of directional growth response. The only available information about the p...
An important life history trait of macroalgae species is the physiological ability to cope with nutrient limiting conditions, which seasonally occur in temperate coasts while other environmental factors are adequate (e.g., sufficient light). Nitrogen (N) and Phosphorus (P) uptake kinetics and field growth limitation were investigated in the perenni...
In temperate areas, lack of nutrients during summer, particularly N, is the main limiting factor of macroalgal growth. However, Nemo lion helminthoides (Velley) Batters in northern Spain is conspicuous in the field during this time (from mid-May to late-July). Therefore, we assumed that its nutrient requirements are low enough to be sustained by tr...
Three species of Gelidiales ( Gelidium arbuscula, Gelidium canariense and Pterocladiella capillacea ) (Rhodophyta) were selected due to their abundance in the marine lower intertidal of the north coast of the island of Tenerife (Canary Islands), to assess, using PAM fluorescence, the importance of irradiance and exposure to air on vertical distribu...
An assessment of the effects of the 'Prestige' oil spill on intertidal, macroalgal assemblages was carried out comparing abundance data obtained before and after the spill. Four zones in the North and Northwest coast of Spain were sampled, one of them located at the immediate vicinity of the spill, the zone most heavily oiled. Macroalgal assemblage...
Following the accident of the oil tanker ‘Prestige’, we surveyed the large scale fuel deposition patterns on the Cantabrian shore (northern Spain) covering three regions (from west to east): (i) Asturias, west of Cape Peñas (24 segments surveyed); (ii) Asturias, east of Cape Peñas (33 segments surveyed); and (iii) Cantabria (also east of Cape Peñas...
Light has been identified as one of the main factors affecting seaweed ecophysiology. We investigated the dependence of nutrient metabolism on sun and shade light conditions and whether episodes of upwelling of nutrient-rich subsuperficial water could reduce the summer nutrient limitation driving physiological changes in Palmaria palmata (L.) Kuntz...
Terrestrial algae are a common component of urban ecosystems, but the factors that affect their distribution are poorly understood. Rosenvingiella radicans is a filamentous green alga widespread in Atlantic Europe, where it often produces green patches at the base of urban walls. The distribution of this alga has been analysed by Chi-Square Automat...
The aim of this study was to adapt the techniques of rope culture to the cultivation of the edible seaweed Palmaria palmata on the northern Spanish coast. Vertical rope rafts were installed in two locations. Fronds were attached to 4-mm polyethylene ropes that were suspended from a steel frame secured in position using weights and buoys. In the fir...
Two species of Phycopeltis (Trentepohliaceae, Chlorophyta) were found to occur epiphytically on leaves of ivy in Asturias, north-western Spain. The larger species, consisting of disk-shaped thalli up to 1400 mum wide, with vegetative cells 9-18 mum long and 5-11 mum wide, is referred to Phycopeltis arundinacea (Montagne) De Toni. Its morphology is...
Limpets were excluded from barnacle-dominated areas in 2 semi-exposed localities on the shore of northern Spain. We tested the hypotheses that a macroalgal canopy would develop and barnacle cover would decrease in exclusion quadrats. Spatial replication considered localities and sites within localities, while temporal replication considered 2 seaso...
The N and P uptake responses were studied in a northern Spanish population of the edible red seaweed Palmaria palmata (Linnaeus) Kuntze. The fronds were incubated at different concentrations, and the nutrient depletion in the medium was measured at successive times to calculate uptake rates. Palmaria palmata uptake response was biphasic and nonsatu...
spatial variation in the recruitment of the intertidal barnacles Chthamalus montagui and Chthamalus stellatus was examined over an European scale. The study was carried out using standardised protocols at a series of locations. The five locations chosen (SW Ireland, NW Spain, SW Portugal and NW and NE Italy) span a large part of the range of these...
Liagora viscida and L. distenta grow on small boulders in rockpools at Campiello (Asturias, north-west Spain). This coast forms the northern limit of the geographical distribution of L distenta in the north-east Atlantic. Gametophytes of both species were only evident from June to October. From June onwards, they increased in abundance, reaching a...
The annual variation of major nitrogen pools, phosphorus, carbon, ash, and thallus water content in relation to seasonal environmental changes was studied in two northern Spanish populations of the edible seaweed Palmaria palmata (Linnaeus) Kuntze. Observed patterns were investigated using Spearman rank order correlation coefficients. There were si...
Fertile male gametophytes of Gelidiella tenuissima are described for the first time, from cultured plants collected in Gran Canaria (Canary Islands, Spain). The morphology of male reproductive structures in this species is similar to other gametophytes referred to the Gelidiales, but different from the recently described male gametophyte of the typ...
The nomenclature and the type material of the entity presently known as Gelidiella pannosa (Feldmann) Feldmann & Hamel are considered. It is concluded that G. tenuissima Feldmann & Hamel is the correct name for the species lectotypified by the specimen located in the lower left corner of the herbarium sheet 7913802 of Herb, Thuret (PC, Paris), coll...
The variations of photosynthesis and C, N and mannitol content were analyzed in the co-existing invasive species Sargassum muticum and the native Cystoseira nodicaulis. Both species exhibited similar seasonal patterns of photosynthesis, with a significant decay in P-max in summer, which can be attributed to nutrient limitation. Nitrogen content was...
Gelidium maggsiae sp. nov. is described from plants found in shallow subtidal maerl beds off the west coast of Ireland, where it attaches to detached coralline algae by peg-like rhizoids. Rhizines are more abundant in the medullary region than in the cortex and erect axes display a prominent central row formed by the axial and periaxial filaments....
The nitrogen status of Gelidium latifolium on the north coast of Spain was monitored for a 2 year period from 1990 to 1991. Each summer, the population showed obvious symptoms of nitrogen (N) limitation, such as thallus 'bleaching'. Minimum N content (as % of dry weight), highest C/N ratio (above 45) and lowest protein (< 10% dry weight) and phycob...
The effect of temperature, air exposure, salinity and light have been tested for three species of Gelidium on the basis of photosynthetic and growth responses in order to assess the zonation patterns observed on the Atlantic coasts of northern Spain. The vertical distribution of three Gelidium species is described: G. sesquipedale reaches its limit...
Growth and reproductive strategies of Sargassum muticum and Cystoseira nodicaulis are compared in the lower limit of the intertidal zone. Both species have similar life-histories but there is a time segregation in their use of resource as well as differences in their allocation. S. muticum responds directly to changes in conditions and resources: i...
Unialgal isolates of Gelidium latifolium from northern Spain and western Norway were compared with respect to specific growth rate, when kept under different combinations of light (20, 50, 100, 200, 300 mumol m-2s-1) and temperature (17, 20, 24, 28, 31-degrees-C). The Norwegian isolate grew almost twice as fast as the Spanish isolate under all comb...
A population of Gelidium latifolium (Greville) Bornet et Thuret (Rhodophyta) from Portstewart, County Antrim, Northern Ireland, was dominated by tetrasporophytes. When grown in culture, excised tips from 10 non-reproductive individuals all formed tetrasporangial branches. Chromosome counts in mitotic nuclei of vegetative cells from cultured tetrasp...
Seasonal cycles of environmental factors (temperature, day-length, nutrient concentration) and changes in Gelidium latifolium biomass, percentage reproduction and size are given, and non-parametric correlation is used to quantify possible relationships. The results are compared with growth experiments, testing effects of total light dosage, agitati...
The first occurrence and establishment of a population of Sargassum muticum in a rocky intertidal area on the Asturian coast of northern Spain is reported. Some competitive attributes of Sargassum muticum, such as photosynthetic and growth rates were compared with other indigenous macrophytes.
