In this study, we determined the soundscape of protected and non-protected marine areas between January and April 2016. Sonobuoy (a device for sound monitoring) recordings began at sunset and lasted approximately 12 hours per day. The results show a complex soundscape dominated by biological sounds produced by crustaceans and fish. Six fish chorus-dominant frequencies between 200 and 1000 Hz occurred at a similar time each day, except for chorus I. The choruses consisted of high-energy callings after the last reef line within the protected area. However, fish choruses showed low energy levels in unprotected areas. The results show the importance of protected areas for fish populations and the usefulness of passive acoustics to monitor biodiversity of sounds of commercial fish in Brazilian tropical costal reefs.</p> Alfredo Borie, Sergio Magalhães Rezende, Beatrice Padovani Ferreira, Mauro Maida, Craig Radford, Paulo Travassos Copyright (c) 2021 Consejo Superior de Investigaciones Científicas (CSIC) https://creativecommons.org/licenses/by/4.0 http://scientiamarina.revistas.csic.es/index.php/scientiamarina/article/view/1887 Tue, 20 Apr 2021 00:00:00 +0200 The elephant in the room: first record of invasive gregarious species of serpulids (calcareous tube annelids) in Majorca (western Mediterranean) http://scientiamarina.revistas.csic.es/index.php/scientiamarina/article/view/1888 <p>Although there are several nuisance species of serpulids reported worldwide, the present study shows that some of them have been overlooked even in geographic areas that are considered well studied. We report for the first time in Majorca the invasive species Ficopomatus enigmaticus and the first records for the Balearic Islands of the also non-native species <em>Hydroides dianthus, H. dirampha, H. elegans</em> and <em>H. nigra</em>. The most abundant species were <em>F. enigmaticus</em>, found at higher densities in Portixol (with up to 280 ind. m<sup>–2</sup>), and <em>H. elegans</em>, found at highest densities in the port of Palma (with up to 270 ind. m<sup>–2</sup>). Species have been identified after morphological examination and corroborated by mitochondrial DNA sequence data: cytochrome c oxidase subunit 1 (COI) and cytochrome b (Cytb). Molecular data show that the same haplotypes have been found in distant and disjoint biogeographic areas worldwide, which is only explicable by unintentional translocation of specimens through vectors (i.e. ship hulls or ballast water). Species delimitation analyses support previous findings that species complexes are common in both <em>Ficopomatus</em> and <em>Hydroides</em>. In fact, only among the Majorcan samples were we able to detect three species of the <em>F. enigmaticus</em> species complex, two of the <em>H. elegans</em> species complex and two of the <em>H. dianthus</em> species complex. The genetic distances between members of the <em>F. enigmaticus</em> species complex are 8.7% to 16.7% in COI sequences. The species of Hydroides hold 5.4% to 47.6 % genetic divergence between species of the same complex.</p> Maël Grosse, Roberto Pérez, Mateo Juan-Amengual, Joan Pons, María Capa Copyright (c) 2021 Consejo Superior de Investigaciones Científicas (CSIC) https://creativecommons.org/licenses/by/4.0 http://scientiamarina.revistas.csic.es/index.php/scientiamarina/article/view/1888 Tue, 20 Apr 2021 00:00:00 +0200 Behaviour and body patterns of Octopus vulgaris facing a baited trap: first-capture assessment http://scientiamarina.revistas.csic.es/index.php/scientiamarina/article/view/1889 <p>This study highlights for the first time individual differences in ethology and vulnerability of <em>Octopus vulgaris</em> (i.e. body postures, movements and skin displays) facing passive baited traps. Common octopus exposed to a baited trap during three consecutive first-capture tests exhibited diverse behavioural and body pattern sequences resembling when the octopus searches for and hunts its wild prey. Overall, they first visually recognized new objects or potential preys and rapidly moved out of the den, exploring, grabbing and approaching the trap with the arms (chemotactile exploration), and capturing the bait with the arms and feeding on top over long periods inside the trap. Simultaneously, <em>O. vulgaris</em> displayed diverse skin textural and chromatic signs, the regular pattern being the most frequent and long-lasting, followed by broad mottle, passing cloud and dark patterns. All individuals (n=8) caught the bait at least once, although only five octopuses (62.5%) entered the trap in all three tests. In addition, high variability among individuals was observed regarding behaviour and body patterns during the first-capture tests, which might evidence different individual temperaments or life-history traits. Differences in behavioural responses at individual level might have population consequences due to fisheries-induced selection, although there is a high necessity to assess how behavioural traits might play an important role in life-history traits of this species harvested by small-scale trap fisheries.</p> Marta Dominguez-Lopez, Guillermo Follana-Berná, Pablo Arechavala-Lopez Copyright (c) 2021 Consejo Superior de Investigaciones Científicas (CSIC) https://creativecommons.org/licenses/by/4.0 http://scientiamarina.revistas.csic.es/index.php/scientiamarina/article/view/1889 Tue, 20 Apr 2021 00:00:00 +0200 Population biology of sympatric species of Caprella (Amphipoda: Caprellidae) in a tropical algal bed http://scientiamarina.revistas.csic.es/index.php/scientiamarina/article/view/1890 <p>The population biology of the three sympatric species of caprellids (<em>Caprella danilevskii, C. equilibra</em> and <em>C. scaura</em>) associated with a <em>Sargassum</em> bed was studied in the northern coast of São Paulo state, Brazil. Samplings were carried out monthly from October 2010 to February 2012. In each month, 25 fronds of <em>Sargassum</em> were randomly collected through snorkelling. The caprellids were identified, counted, classified by sex and separated into size classes. <em>Caprella danilevskii</em> was the most abundant species, with 14939 specimens recorded. The body size of males was larger than that of females for <em>C. danilevskii</em> and <em>C. equilibra</em>, and the sex ratio was skewed toward males for all species. The size-frequency distribution was polymodal for <em>C. danilevskii</em> and <em>C. scaura</em> and bimodal for <em>C. equilibra</em>. Mature males of <em>C. scaura</em> and <em>C. equilibra</em> were recorded in all size classes. The last size classes (from 8.3–9.4 to 12.7–13.8 mm) were dominated by mature males. Mature and ovigerous females were more frequent in intermediate size classes. Significant temporal variations were recorded for the three species with higher densities in spring and summer that are related to higher algal biomass; but other environmental factors are certainly important for explaining caprellid density variation.</p> Daniela Rejane de Paula, Karla Vanessa Souza Cunha, Isabela Corsini Pereira Garcia, Samara de Paiva Barros-Alves, Giuliano Buzá Jacobucci Copyright (c) 2021 Consejo Superior de Investigaciones Científicas (CSIC) https://creativecommons.org/licenses/by/4.0 http://scientiamarina.revistas.csic.es/index.php/scientiamarina/article/view/1890 Tue, 20 Apr 2021 00:00:00 +0200 Ommastrephid squid spawning in the North Sea: oceanography, climate change and species range expansion http://scientiamarina.revistas.csic.es/index.php/scientiamarina/article/view/1891 <p>The lesser flying squid (<em>Todaropsis eblanae</em>) and the shortfin squid (<em>Illex coindetii</em>) are two abundant ommastrephids of the northeast Atlantic. Spawning ground existence was inferred from the captures of mature, mated females in summer 2016–2019 and their occurrences were compared with respective oceanographic data from international surveys to gain insight into environmental predictors of their presence throughout the North Sea. Spawning <em>T. eblanae</em> were found in relatively cooler and more saline waters (6–8°C, 34.2–35.1 psu) in the northern North Sea linked to the Fair Isle Current and East Shetland Atlantic Inflow, whilst spawning <em>I. coindetii</em> occurred across the entire North Sea (mostly at 9–10.5°C, 34.1–34.8 psu). We hypothesize that a combination of water salinity and water temperature are key factors in the spatiotemporal distribution of spawning ommastrephid squids as they define water density that is crucial for pelagic egg mass to attain neutral buoyancy.</p> Christopher J.
