“…As for S. acus in PNIA, dominant pipefish species form monospecific populations [ 54 , 96 ] but many European pipefish species may vary their habitat occupancy and overlap a great deal [ 96 ], as shown in PNAC. Seagrass meadows are lacking in PNIA [ 29 , 30 ] but PNAC seabed was partially covered by large extensions of seagrass meadows ( P. oceanica and C. nodosa ), which is a typical cover enhancing the occurrence of syngnathids in some Mediterranean areas [ 99 ]. That is the case of S. typhle , a pipefish that preferentially displays an upright position in seagrasses with narrow leaves (e.g.…”

Background Syngnathid fishes (Actinopterygii, Syngnathidae) are flagship species strongly associated with seaweed and seagrass habitats. Seahorses and pipefishes are highly vulnerable to anthropogenic and environmental disturbances, but most species are currently Data Deficient according to the IUCN (2019), requiring more biological and ecological research. This study provides the first insights into syngnathid populations in the two marine Spanish National Parks (PNIA—Atlantic- and PNAC—Mediterranean). Fishes were collected periodically, marked, morphologically identified, analysed for size, weight, sex and sexual maturity, and sampled for stable isotope and genetic identification. Due the scarcity of previous information, habitat characteristics were also assessed in PNIA. Results Syngnathid diversity and abundance were low, with two species identified in PNIA (Hippocampus guttulatus and Syngnathus acus) and four in PNAC (S. abaster, S. acus, S. typhle and Nerophis maculatus). Syngnathids from both National Parks (NP) differed isotopically, with much lower δ15N in PNAC than in PNIA. The dominant species were S. abaster in PNAC and S. acus in PNIA. Syngnathids preferred less exposed sites in macroalgal assemblages in PNIA and Cymodocea meadows in PNAC. The occurrence of very large specimens, the absence of small-medium sizes and the isotopic comparison with a nearby population suggest that the population of Syngnathus acus (the dominant syngnathid in PNIA) mainly comprised breeders that migrate seasonally. Mitochondrial cytochrome b sequence variants were detected for H. guttulatus, S. acus, and S. abaster, and a novel 16S rDNA haplotype was obtained in N. maculatus. Our data suggest the presence of a cryptic divergent mitochondrial lineage of Syngnathus abaster species in PNAC. Conclusions This is the first multidisciplinary approach to the study of syngnathids in Spanish marine NPs. Habitat preferences and population characteristics in both NPs differed. Further studies are needed to assess the occurrence of a species complex for S. abaster, discarding potential misidentifications of genus Syngnathus in PNAC, and evaluate migratory events in PNIA. We propose several preferential sites in both NPs for future monitoring of syngnathid populations and some recommendations for their conservation.

“…Estas plantas colonizaron con éxito o medio mariño, como demostra a súa distribución xeográfica, estendida ao longo de todos os océanos do planeta, coa excepción do océano Antártico (Green e short, 2003). Constitúen un grupo reducido de especies, aproximadamente 60 no conxunto do planeta, entre as que cabe salientar dúas especies do xénero Zostera, Zostera marina e Zostera nolteii, ambas presentes nas rías e esteiros de Galicia (ruiz et al, 2015;García-redondo, Bárbara e díaz-Tapia, 2019). son plantas perennes, con forma de herba, que presentan follas que se colocan de xeito alterno ao longo do eixo principal da planta.…”

“…son numerosas as áreas xeográficas do planeta nas que as pradarías mariñas coexisten con actividades de explotación de recursos mariños, tanto pesca como marisqueo (Norlund, unsworth, Gullstrom e Cullen-unsworth, 2017). No caso de Galicia, un traballo recente publicado por García-redondo et al (2019) indica que o 80% da superficie cuberta por Zostera marina está afectada polas presións ambientais asociadas á actividade marisqueira. o marisqueo causa perturbacións físicas sobre as pradarías desta especie, podendo chegar a reducir a súa biomasa de xeito moi significativo, aínda que a capacidade de recuperación durante o período de veda da extracción de moluscos pode ser moi elevada (Barañano, Fernández, méndez e Troncoso, 2017).…”

Analízase a situación da pradaría de Zostera nolteii do banco de marisqueo de bivalvos de Testal (Noia), mediante a investigación desenvolvida por escolares, coa dirección de científicos. A finalidade do programa de Ciencia Escolar de Climántica é contribuír ao coñecemento científico mediante a obtención de series de datos útiles para a realización de investigacións de interese a escala local. Neste caso, analizouse a relación existente entre as abundancias de bivalvos de interese comercial e a presenza da fanerógama Zostera nolteii co obxectivo de capacitar aos alumnos para facer ciencia sobre os impactos humanos sobre os servizos ecosistémicos máis relevantes da súa contorna. Con esta colaboración entre Ciencia e Escola, conseguiuse aumentar a competencia científica do alumnado, ao tempo que se realizaron transferencias bidireccionais ciencia – escola no eido da investigación e educación sobre o cambio global.A actividade que se describe neste traballo ten como obxectivo xeral coñecer a relación existente entre a diversidade de organismos animais do banco do Testal e a presenza e distribución espacial da fanerógama Zostera nolteii, para así entender o seu papel como xeradora de estructura no ecosistema intermareal de sustrato brando.

“…Zostera marina is the most widely distributed species among marine phanerogams; in Galicia, it forms vast meadows in intertidal and shallow subtidal areas (Míguez, 2003;Cacabelos et al, 2015;García-Redondo et al, 2019). The Galician coastline features rias and inlets that provide optimal conditions for the growth of Zostera marina (García-Redondo et al, 2019).…”

The increase in greenhouse gases (GHG) has been constant since the Industrial Revolution. For this reason, different international organizations have devoted special attention to GHG sinks such as terrestrial soils and ecosystems. However, the initially estimated balances did not include the carbon stock associated with ocean waters, coastal soils and sediments, known as blue carbon. Currently, blue carbon sinks are the subject of numerous studies due to the limited information available, especially on the Atlantic coast of the Iberian Peninsula. We studied the organic C stock present in soils and in Zostera marina biomass in the two main meadows in the Ría de Ferrol (O Baño and Castelo de San Felipe). The carbon stock associated with biomass was 0.37 Mg C ha−1, with 0.18 Mg C ha−1 corresponding to the epigeal portion and 0.19 Mg C ha−1 to the hypogeal portion. Soil carbon stock was much higher: 4.11 Mg C ha−1 at a depth of 5 cm and 82.14 Mg C ha−1 at a depth of 1 m. Together with carbon values in biomass, a stock of 82.5 Mg C ha−1 was obtained for the whole Ría de Ferrol. Z. marina accounted for 8.25% of total C in the Ría de Ferrol. These values were higher than those found in other regions. Isotope ratios (δ13C, δ15N) and C/N ratios indicated that the organic C stock in the O Baño soil may receive important organic matter inputs of terrestrial origin, while in San Felipe, it seems to have a marine origin.
