(Francesc Peters) (Soporte Técnico Revistas-CSIC) Sat, 30 Dec 2023 00:00:00 +0100 OJS 60 An in-depth study of the biology, trophic ecology and catchability of the invasive pufferfish Lagocephalus sceleratus from southern Turkey, eastern Mediterranean Sea <p>The silver-cheeked toadfish (<em>Lagocephalus sceleratus</em>) is an invasive species of highest concern. Its population must be controlled to mitigate its negative impacts on marine ecosystems, fishers, fisheries and human health. This study thoroughly investigates the biology, diet and catchability of the&nbsp;<em>L. sceleratus</em>&nbsp;stock from Finike, Turkey from March 2017 to February 2018 in order to better manage its invasion. A total of 751 specimens were sampled for this study with a M/F ratio of 1.25/1. The species becomes sexually mature at three and a half years of age, and Lm<sub>50</sub>&nbsp;was 41.39 cm for males and 42.08 cm for females. Its spawning season in this region was from June to August, peaking in July. Its diet was mostly crustaceans in spring, fish in summer and both fish and crustaceans in winter. This species consumed a large amount of other pufferfish species, resulting in over a quarter of its fish diet. The trophic level of&nbsp;<em>L. sceleratus</em>&nbsp;was 4.41, demonstrating that it is indeed a top predator carnivore in the eastern Mediterranean Sea. Ingested fishing gear parts such as net pieces and hooks were found in about 10% of the fish. A slight modification of longlines using steel branch lines and a swivel hook resulted in double the catch per unit effort than standard longlines, so this technique can be used to target and control more of this invasive species, which is a national priority.</p> Hasan Ersönmez, Caner Enver Özyurt, Sinan Mavruk, Taner Yıldız, Aylin Ulman Copyright (c) 2023 Consejo Superior de Investigaciones Científicas (CSIC) Wed, 20 Dec 2023 00:00:00 +0100 Taxonomic revision and molecular phylogeny of Pisa (Decapoda: Majoidea: Epialtidae), including the description of a new genus of Pisinae <p>The spider crabs of the genus&nbsp;<em>Pisa</em>&nbsp;Leach, 1814&nbsp;(Epialtidae: Pisinae) are reviewed in this study based on morphological and molecular data (16S and COI genes). From these results, a new genus,&nbsp;<em>Afropisa</em>&nbsp;n. gen., is established for the clade composed of&nbsp;<em>Pisa carinimana</em>&nbsp;Miers, 1879,&nbsp;<em>Pisa calva</em>&nbsp;Forest and Guinot, 1966&nbsp;and&nbsp;<em>Pisa sanctaehelenae</em>&nbsp;Chace, 1966&nbsp;based on carapace morphology, rostrum, pterygostomian tubercles and male gonopod 1. Additionally,&nbsp;<em>Lissa chiragra</em>&nbsp;(Fabricius, 1775) is transferred to&nbsp;<em>Pisa</em>&nbsp;based on morphological (adults and larvae) and molecular evidence. Furthermore, the status of&nbsp;<em>Pisa hirticornis</em>&nbsp;(Herbst, 1804) is discussed and clarified. The phylogenetic relationships between several Pisinae&nbsp;Dana, 1851&nbsp;genera, as revealed by molecular data, are discussed. An illustrated identification key of eastern Atlantic and Mediterranean species of Pisinae is provided.</p> Isabel Muñoz, J. Enrique García-Raso, José A. Gónzalez, Evandro P.

Nevertheless, valuing wildlife can be of great significance to improve decision-making in the conservation field, as it can provide a complementary perspective based on economic principles. Whale-watching provides an opportunity for the economic valuation of wildlife. Specifically, it offers a framework in which the economic revenue allows the economic valuation of the targeted cetaceans to be estimated through the direct and indirect expenditure of the tourists who purchase whale-watching tours. Here, we performed an economic analysis based on population abundances of the three main species targeted by the whale-watching companies in the Strait of Gibraltar (Spain): long-finned pilot whales (<em>Globicephala melas</em>), common dolphins (<em>Delphinus delphis</em>) and killer whales (<em>Orcinus orca</em>). These species generated a total annual income of €4,089,056, €1,876,833, and €505,389, respectively, and each individual would generate an average of €14,048, €951, and €36,099 each year, respectively. Incorporating life expectancy, this corresponded to a total population value of €112,426,185, €16,685,147, and €19,171,107, respectively, over their lifetime. These values provide an idea of the potential contribution of cetaceans to the local economy but only represent their non-consumptive value based on tourism. Our results reinforce the idea that a sustainable, high-quality whale-watching culture, under ACCOBAMS High-Quality Whale-Watching requirements, should be promoted to ensure a sustainable industry, stable economic income and the viability of cetacean populations in the Strait of Gibraltar.</p> Jazel Ouled-Cheikh, Joan Giménez, Philippe Verborgh, Carolina Jiménez-Torres, Pauline Gauffier, Ruth Esteban, Renaud de Stephanis Copyright (c) 2023 Consejo Superior de Investigaciones Científicas (CSIC) Wed, 20 Dec 2023 00:00:00 +0100 Diel cycle of two recurrent fish sounds from mesophotic coral reefs <p>Mesophotic coral ecosystems (MCEs) are the deepest part of tropical coral reefs, ranging from depths of 30 to over 170 m. Despite their significance, MCEs remain largely unexplored due to the challenges associated with accessing these depths. However, the application of passive acoustic monitoring methods (PAM) is a suitable approach for studying fish communities within these unique habitats. In French Polynesia, recent PAM studies have unveiled a higher occurrence of frequency-modulated fish sounds in MCEs than in shallower reef environments. This study aims to further enhance our understanding of fish sounds in MCEs by examining their diel patterns, focusing specifically on the two most abundant frequency-modulated fish sounds that were recorded at depths of 60 and 120 m at six Polynesian islands. Both sound types occurred predominantly during the beginning and the end of nocturnal periods. The presence and abundance of these sounds exhibited variation between the islands, highlighting potential regional disparities in vocal activity or the bathymetric distribution of the sound-producing species. By characterizing the diel cycles and bathymetric differences in relation to their geographical distribution, this study offers preliminary insights into identifying the potential sound-producing species.</p> Xavier Raick, Pierre Collet, Under The Pole Consortium, David Lecchini, Frédéric Bertucci, Eric Parmentier Copyright (c) 2023 Consejo Superior de Investigaciones Científicas (CSIC) Wed, 20 Dec 2023 00:00:00 +0100 In Memoriam, Andrés Barbosa Alcón, researcher at the National Museum of Natural Sciences, CSIC (1964-2023) Asunción de los Ríos, Santiago Merino Copyright (c) 2023 Consejo Superior de Investigaciones Científicas (CSIC) Wed, 20 Dec 2023 00:00:00 +0100
