The health of the communities of corals and crustose coralline algae was studied in the years 2001, 2012 and 2017. The probable effect of hurricanes and sea surface temperature on these communities was also assessed. The area was only affected by three hurricanes and a tropical storm from 2000 to 2017. Sea surface temperature showed an increasing trend (by 0.03<strong>°</strong>C). The highest percentage of old mortality was recorded in 2001 (74% on the fore reef and 53% on reef crests) and the lowest of recent mortality in 2012 (0.03% on the fore reef and 0.17% on reef crests). Coral cover increased on the fore reef by between 3% and 2% in 2017 in comparison with 2001 and 2012. On the reef crests, the highest cover percentage was in 2001 (14.8%). Unlike local stressors, it was determined that hurricanes and sea surface temperature have likely negatively affected the coral reefs, particularly on reef crests. Both habitats have shown resistance and/or recovery capacity from the impacts suffered after 2001, which suggests some level of resilience.</p> Leslie Hernández-Fernández, Martín Merino-Ibarra, Felipe Matos Pupo, Roberto González-De Zayas 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/1919 mi, 15 jun 2022 00:00:00 +0200 Predicting the breeding hotspots of the southern right whale, Eubalaena australis (Cetartiodactyla: Mysticeti), along the southern Brazilian coastline https://scientiamarina.revistas.csic.es/index.php/scientiamarina/article/view/1920 <p>To predict the potential breeding hotspots of southern right whales in southern Brazil, we used a Maxent model with a “presence-only” dataset. The dataset was obtained from a systematic aerial survey and public records of the Programa de Monitoramento de Cetáceos da Bacia de Santos and Sistema de Apoio ao Monitoramento de Mamíferos Marinhos. Because of spatial autocorrelation, 528 records out of 3028 were used in the modelling process. The explanatory variables used in the models were coastal distance, linearity, slope and substrate type. The models were created separately for unaccompanied adults (Ad) and mother-calf pairs (Fe). Both models showed good accuracy according to their area under the curve values (Ad=0.974; Fe=0.958). Coastal distance was the most relevant explanatory variable for the unaccompanied adult model (54%), whereas coastal linearity was more relevant for the mother-calf pair model (82%). The estimated area for mother-calf pairs was more restricted to coastal areas than that for unaccompanied adults, possibly owing to the high number of shelter areas for calves near the coast. This is the first study to predict the potential breeding hotspots of southern right whales in Brazil and its results will allow for a more directed management of these whales and provide further research opportunities.</p> Eduardo Pires Renault-Braga, Karina R.

It was historically reported from San Matías Gulf, Argentina in the Atlantic Ocean to the Peruvian coast in the Pacific. A recent study analysed the intraspecific variation of this species along its distribution range and the genetic results indicated the presence of cryptic diversity. Two evolutionary clades were found: a southern clade (from cold-temperate waters) and a northern clade (from warm-temperate waters). New results based on geometric morphometrics supported the description of&nbsp;<em>Ensis loboi</em>&nbsp;n. sp. for the northern clade. The southern clade retains the name due to type locality of&nbsp;<em>E. macha</em>&nbsp;in Chilo<em>é</em>, Chile. The description of&nbsp;<em>Ensis loboi</em>&nbsp;n. sp. for the southeastern Pacific Ocean has important implications for future studies focused on fisheries management and biogeographical radiation of the group.</p> Javier H.

However, few elasmobranch species have been assessed because information on their basic biological parameters is lacking for most species.&nbsp;<em>Raja polystigma</em>&nbsp;is a poorly studied endemic skate in the Mediterranean. The aim of this work is to determine some basic life history parameters of this skate in the Balearic Islands. Data were collected from commercial catches and during MEDITS surveys. Total length varied from 17 to 59 cm for both sexes, with a higher proportion of females than males. Allometric and morphometric relationships differed between sexes, females being heavier for a given size. Females matured at a larger size than males (L<sub>50</sub>&nbsp;47.7 cm and 38.4 cm, respectively). Potential fecundity ranged between 11 and 45 yolked oocytes per female, and spawning was observed mainly during winter and spring. Persistent hotspots of adults and juveniles were detected on the shallow shelf off the northwest of Mallorca and east of Menorca, with adults being found mainly in the shallow and juveniles in deeper areas. Time series of abundance and frequency of appearance showed stable trends throughout the study period (2003-2018).</p> Francesca Ferragut-Perello, Maria Valls, Miquel A.

(Annelida: Capitellidae) in laboratory conditions https://scientiamarina.revistas.csic.es/index.php/scientiamarina/article/view/1923 <p>The endobenthic deposit-feeder polychaetes of the&nbsp;<em>Capitella capitata</em>&nbsp;species complex have a strong relation with organically enriched sediments (OES). The effect of non-organically enriched sediments (NOES, 0.09% of organic content) and OES (6.26% of organic content) on mortality, growth and development of juveniles and adults of&nbsp;<em>Capitella teleta</em>&nbsp;(cultured for more than 40 years) and&nbsp;<em>Capitella</em>&nbsp;sp. from Alfacs Bay, Tarragona, Spain (acclimatized for one month) were analysed in laboratory conditions. Juveniles and adults were exposed (all individuals separately in different dishes) to the two treatments, periodically observed and measured until death. NOES considerably impaired survival, growth rates and development of juveniles and adults of both species, which showed highly variable negative growth rates under OES. Juvenile and adult&nbsp;<em>C. teleta</em>&nbsp;showed an improved maturity under OES, even producing two protandrous and one protogynous individuals, whereas no&nbsp;<em>Capitella</em>&nbsp;sp. reached maturity during the experiment.</p> Nuria Méndez 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/1923 mi, 15 jun 2022 00:00:00 +0200 Effects on faunistic composition and population characteristics of decapod crustaceans after the implementation of a fisheries no-take area in the NW Mediterranean https://scientiamarina.revistas.csic.es/index.php/scientiamarina/article/view/1924 <p>The establishment of fisheries no-take areas is considered an effective method for the recovery of populations of exploited species and their habitats. Here we study the faunistic composition of decapod crustaceans after the implementation of a no-take area in the Gulf of Roses (NW Mediterranean) in 2014. We studied the occurrence (presence/absence) and density of all decapod crustaceans sampled by trawling inside and outside a no-take area from March 2015 to July 2018. Sizes were assessed for all common species. A total of 33 species of decapod crustaceans were recorded. Four species showed significantly higher occurrences in the no-take area and three in the open area, while significantly higher densities were found for four species in the no-take area and three in the open area. Multivariate analysis showed marked differences between the no-take area and the open area, while also showing that the two areas were undergoing a divergence. The comparison of sizes between the two zones showed species-specific patterns that in many cases showed that both the smallest and the largest individuals were present in the no-take area, suggesting that the closing of this area would be important for recruitment and juvenile development, as well as for protection of large-sized individuals. All evidence indicates that the establishment of the no-take area has led to an improvement in biodiversity and species population descriptors.</p> Andrea Padilla, Laura Recasens, Marc Balcells, Ulla Fernández de Arcaya, Pere Abelló 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/1924 mi, 15 jun 2022 00:00:00 +0200
