Lumbrinerids are amongst the most abundant and diverse polychaete families in worldwide continental shelves, and have received attention recently through the description of several new species and new occurrences. Herein, a total of four lumbrinerid species are firstly reported in the eastern and southern Spanish continental shelf, extending their biogeographic distribution to the western Mediterranean Sea and increasing up to 25 the number of species known in the Iberian Peninsula coasts. New insights on taxonomy, ecological and biogeographic preferences and an updated taxonomic key for Iberian coasts and surrounding areas are also provided.

AbstractThe invasive blue crab Callinectes sapidus has been frequently recorded during the last years along the NW Mediterranean Sea, leading to established populations. Two megalopae of C. sapidus were found during two different oceanographic surveys in open waters of the Balearic Archipelago, in July 2005 and October 2011, previous to the first reference of adult specimens documented in the Balearic sub-basin. The analyzed environmental conditions of the sampling periods allowed us to hypothesize the likely introduction pathways, namely by maritime transport and surface currents. Furthermore, the recorded megalopae seem to enlarge the life history of C. sapidus in regard to its native area, where spawning peaks occur in late July and early August.

Age Model

In the present study the life history of blonde ray Raja brachyura from Sardinian waters (central-western Mediterranean) was investigated and the results compared with previously published data on this species. The age, growth and reproduction were studied using 1792 specimens caught between 2005 and 2013. Females ranged from 13.1 to 105.5 cm in Total length (TL) and males from 18 to 96.5 cm TL. This species was sexually dimorphic, with TL females attaining a larger size than males. Both females and males showed allometric growth (b>3) and we found significant differences in the relationship between length and weight among sexes. The von Bertalanffy growth function (3 parameters), which provided the following values: L∞ = 111.14 cm TL, k = 0.10 and t0 = -1.3 for females, and L∞ = 108.81 cm TL, k = 0.11 and t0 = -1.2 for males, was the best-fit age model. R. brachyura showed a relatively slow growth rate with males slightly more rapid than females. Length and age at maturity were 87.2 cm and 14 years for females and 80.8 cm and 10 years for males. This ray exhibited a restricted reproductive cycle from late May to August, confirmed by the seasonal evolution of GSI values. Ovarian fecundity reached a maximum of 44 yolked follicles. Given the relative abundance in the Sardinian seas, it is hoped that the results can be useful in the implementation of basic management measures in order to ensure the sustainability of catches of this species in the Mediterranean Sea.

AbstractThe metazoan parasite assemblage of the head of 30 specimens of the Atlantic chub mackerel (Scomber colias) from the western Mediterranean Sea was analysed. Eight species of parasites were found, four mazocraeid monogeneans: Grubea cochlear (prevalence = 10%), Kuhnia scombercolias (59%), K. scombri (52%), Pseudokuhnia minor (86%); three didymozoid trematodes: Nematobothrium cf. faciale (21%), N. filiforme (41%), N. scombri (7%); and one laerneopodid copepod: Clavelissa scombri (7%). Results were compared with previously published data from 14 localities of the eastern Mediterranean Sea and the Atlantic Ocean, using non-parametric univariate and multivariate analyses, and the whole parasite fauna of S. colias was compared with that of the congeners (S. australasicus, S. japonicus and S. scombrus). Parasites showed to reflect the biogeographical and phylogenetic history of host. From a methodological point of view, the use of both non-parametric univariate and multivariate techniques proved to be effective tools to detect dissimilarities between parasite assemblages.

A 29-year wind/wave hindcast is produced over the Mediterranean Sea for the period 1990–2018. The dataset is obtained by downscaling the ERA5 global atmospheric reanalyses, which provide the initial and boundary conditions for a numerical chain based on limited-area weather and wave models: the BOLAM, MOLOCH and WaveWatch III (WW3) models. In the WW3 computational domain, an unstructured mesh is used. The variable resolutions reach up to 500 m along the coasts of the Ligurian and Tyrrhenian seas (Italy), the main objects of the study. The wind/wave hindcast is validated using observations from coastal weather stations and buoys. The wind validation provides velocity correlations between 0.45 and 0.76, while significant wave height correlations are much higher—between 0.89 and 0.96. The results are also compared to the original low-resolution ERA5 dataset, based on assimilated models. The comparison shows that the downscaling improves the hindcast reliability, particularly in the coastal regions, and especially with regard to wind and wave directions.
