His studies were among the first to incorporate various concepts in the literature of aquatic ecology, covering topics such as organisms, ecosystem interactions and evolution. To bring Margalef’s approach into current scientific studies, in this review we explore his vision of aquatic ecology within four interrelated fields of study: ecological theory, microbial diversity, biogeochemical cycles and global environmental changes. Taking inspiration from his studies, we analyse current scientific challenges and propose an integrated approach, considering the unifying concept of Margalef’s Mandala with the aim of improving future studies on aquatic microbial ecology.</p> Ana Rocio Borrero-Santiago, Walter Dellisanti, Andrés Sánchez-Quinto, Javier Moreno-Andrés, Philip Nemoy, Kumari Richa, Patricia Margarita Valdespino-Castillo, Daniel Diaz-de-Quijano, Vicente J.

Although they are relatively well studied throughout Europe, several faunal groups of maerl beds, such as those belonging to the meiofauna, have received little attention. We investigated the meiofaunal abundance, distribution and community structure, with a focus on nematode biomass and diversity, in a maerl area in the Bay of Brest, Brittany, compared with that on a sandy beach (Anse de Dinan, Brittany). Meiofauna was five times more abundant on the maerl bed than on the sandy beach, and 1.5 times more diversified (12 vs. 8 taxa, respectively). Nematode diversity was more than three times higher on the maerl bed than on the sandy beach and showed a distinctive nematode community that was absent from the sandy beach. Maerl beds create more heterogeneous microhabitats and promote a higher diversification of meiofauna and nematode communities than sandy beaches.</p> Federica Rebecchi, Daniela Zeppilli, Elisa Baldrighi, Anna Di Cosmo, Gianluca Polese, Alessandro Pisaniello, Jacques Grall Copyright (c) 2022 Consejo Superior de Investigaciones Científicas (CSIC) https://creativecommons.org/licenses/by/4.0 https://scientiamarina.revistas.csic.es/index.php/scientiamarina/article/view/1913 jue, 07 abr 2022 00:00:00 +0200 Fishery dynamics of blue whiting, Micromesistius poutassou, a highly discarded bycatch species in the NW Mediterranean Sea https://scientiamarina.revistas.csic.es/index.php/scientiamarina/article/view/1914 <p>This study characterized the fishery dynamics of blue whiting, a bycatch species of the bottom trawl Norway lobster fishery, in the NW Mediterranean. Landings and effort data over the last two decades were combined with current information on the spatial distribution of effort and catch, and with the size and age structure of blue whiting over the year. Recruitment to the demersal habitat occurred from 5 cm total length (TL) over the shelf break in spring (April-May), when discards showed the highest values (&gt;95% of the catch). Adults were located over the upper slope, and large individuals (≥26 cm TL) were abundant during the reproductive period (January-March). A decline in landings has been observed in the last decade, probably related to the absence of intense deep convection processes in winter since 2013, which favour recruitment of the species. The effect of exploitation on the decrease in landings cannot be disregarded considering that the bulk of the catch is made up of immature (age 0) individuals, and the presence of old individuals is very low.</p> Joan Mir-Arguimbau, Paloma Martín, Marc Balcells, Joan Sala-Coromina, Ana Sabatés Copyright (c) 2022 Consejo Superior de Investigaciones Científicas (CSIC) https://creativecommons.org/licenses/by/4.0 https://scientiamarina.revistas.csic.es/index.php/scientiamarina/article/view/1914 jue, 07 abr 2022 00:00:00 +0200 Influence of climate on seawater quality and green mussel production https://scientiamarina.revistas.csic.es/index.php/scientiamarina/article/view/1916 <p>This study aimed to investigate the relationships between atmospheric parameters, seawater quality and green mussel production which were cultured in pond, estuary and coastal areas. Seawater and mussel samples were collected from mussel farms in the inner Gulf of Thailand from January to December 2019. Climate data were obtained from the Thai Meteorological Department. The correlations between selected atmospheric and seawater parameters were developed using linear and non-linear models. The influence of seawater quality on mussel production was evaluated using principal component analysis and stepwise multiple linear regression. The effects of atmospheric variation on green mussel productivity were simulated. The results showed that high air temperature and rainfall caused an increase in seawater temperature and a decrease in salinity, respectively. It was observed that the most influential factors affecting mussel production were nutrients and dissolved oxygen in ponds, temperature and salinity in estuaries, and nutrients and pH in coastal areas. The simulation indicated that mussel production can deteriorate when air temperature reaches 34°C and rainfall is higher than 200 mm per month. Our results suggest that under climate change events, locations with less riverine influence can provide higher mussel productivity. These results can be used as a guideline for farmers during a climate change event.</p> Chayarat Srisunont, Treeranut Srisunont, Alongot Intarachart, Sandhya Babel Copyright (c) 2022 Consejo Superior de Investigaciones Científicas (CSIC) https://creativecommons.org/licenses/by/4.0 https://scientiamarina.revistas.csic.es/index.php/scientiamarina/article/view/1916 jue, 07 abr 2022 00:00:00 +0200 Evaluation of heavy metal pollution risk in surface sediment of the South Lagoon of Tunis by a sequential extraction procedure https://scientiamarina.revistas.csic.es/index.php/scientiamarina/article/view/1917 <p>In this study, the total concentrations and chemical forms of heavy metals (Fe, Zn, Pb, Cu, Cr, Cd, and Ni) in surface sediments of the South Lagoon of Tunis located in northeast Tunisia were investigated. Multiple geochemical indices were applied to assess the potential environmental risks. The South Lagoon is a valuable regional resource for fisheries, tourism and aquaculture. Total metal concentrations exhibited significant spatial variation attributed to the principal water circulation direction (east to west). The chemical speciation of Fe, Cr and Ni shows that they were mostly related to the residual fraction (Fe 34.8%, Cr 37.4% and Ni 37.9%), while Pb, Zn, Cu, and Cd were mostly related to the non-residual fraction (labile fraction Pb 89.4%, Zn 26.1%, Cu 71.8% and Cd 84.3%). Pb, Zn, Cu and Cr are of high potential bioavailability. The highest pollution was found on the west side of the lagoon according to the calculated global contamination factors. Besides, individual contamination factors, Pb followed by Zn and Cu, posed the highest risk of contamination. This study shows that, even after dredging, the persistence of low concentrations of some contaminants may cause environmental problems in certain physico-chemical conditions.</p> Myriam Abidi, Asma Yahyaoui, Rim Ben Amor, Lassaad Chouba, Moncef Gueddari Copyright (c) 2022 Consejo Superior de Investigaciones Científicas (CSIC) https://creativecommons.org/licenses/by/4.0 https://scientiamarina.revistas.csic.es/index.php/scientiamarina/article/view/1917 jue, 07 abr 2022 00:00:00 +0200
