New Mediterranean Biodiversity Records (November 2020)
This article includes 23 new records of alien and cryptogenic species in the Mediterranean Sea, belonging to 4 Phyla (Chordata, Echinodermata, Arthropoda and Mollusca), distributed from the Alboran to the Levantine Sea. Records are reported from eight countries listed from West to East as follows: Algeria : new records of the Atlantic blue crab Callinectes sapidus ; Spain : further spread and establishment of the sea slug Lamprohaminoea ovalis in continental shores; Tunisia : first record of the Atlantic Blue Crab Callinectes sapidus in the Gulf of Gabes; Italy : a new occurrence of the pufferfish Lagocephalus sceleratus in Northern Ionian waters; first record of Cephalopholis taeniops in t…
Marine alien species in Italy: A contribution to the implementation of descriptor D2 of the marine strategy framework directive
A re-examination of marine alien species or Non Indigenous Species (NIS) reported in Italian Seas, until December 2018, is provided, focusing on establishment success, year of first record, origin, potential invasiveness, and likely pathways, in particular. Furthermore, their distribution is assessed according to the marine subregions outlined by the European Union (EU) Marine Strategy Framework Directive: Adriatic Sea (ADRIA), Ionian Sea and Central Mediterranean Sea (CMED), and Western Mediterranean Sea (WMED). In Italy, 265 NIS have been detected with the highest number of species being recorded in the CMED (154 species) and the WMED (151 species) subregions, followed by the ADRIA (143) …

Abundance patterns at the invasion front: The case of Siganus luridus in Linosa (Strait of Sicily, Central Mediterranean Sea)
The dusky spinefoot (Siganus luridus) has spread through much of the eastern Mediterranean since its introduction in 1920. In the present study, we monitored the abundance of this invader around the island of Linosa (Strait of Sicily), where the species was first recorded in 2003. Data were periodically collected along two temporal windows, 2005–06 and 2012–15, by both underwater visual census and surface snorkelling. Local ecological knowledge was investigated to gain complementary information. Both approaches highlighted significant proliferation of this tropical invader, with an average abundance of 0.36 individuals per 250m2 across the 0–30-m depth range. Dense aggregations of more than…
On the occurrence of the silverstripe blaasop Lagocephalus sceleratus (Gmelin, 1789) along the Libyan coast
Five individuals of Lagocephalus sceleratus were caught by trammel and gill nets off Ain Al Ghazala, Libya (approximately 32°09'N − 23°15'E) between 15 and 25 m depth in September 2010. Our findings represent the first record of this toxic species from Libya and provide further evidence of its occurrence along North African coasts.
Predicting future thermal habitat suitability of competing native and invasive fish species: From metabolic scope to oceanographic modelling
Global increase in sea temperatures has been suggested to facilitate the incoming and spread of tropical invaders. Here, we determined the effect of temperature on the aerobic metabolic scope of two competing fish species, one native and one invasive, and we predicted their future thermal habitat suitability.

Fish diversity associated with gas platforms: Evaluation of two underwater visual census techniques
Se estudiaron las comunidades ícticas asociadas con plataformas extractivas mediante dos técnicas de censos visuales submarinos: transectos y conteos de puntos móviles. Los datos se tomaron a cuatro profundidades en tres diferentes plataformas situadas en el Mar Jónico (Crotone, Italia). Se registraron un total de 25 especies de peces pertenecientes a 12 familias. Se observaron diferencias significativas entre ambos métodos de muestreo y las profundidades en cuanto a la estructura de la comunidad íctica, la riqueza de especies y la abundancia de peces. El promedio de peces registrado con el método de transectos siempre fue mayor que el registrado mediante puntos móviles, mientras que lo con…

Percnon gibbesi (H. Milne Edwards, 1853) and Callinectes sapidus (Rathbun, 1896) in the Ligurian Sea: Two additional invasive species detections made in collaboration with local fishermen
The non-indigenous crabs Percnon gibbesi (H. Milne Edwards, 1853) and Callinectes sapidus (Rathbun, 1896) (Crustacea, Decapoda, Portunidae) are reported from Genoa and La Spezia, respectively, in the Ligurian Sea at the northern rim of the Mediterranean Sea. Both specimens were collected by fishermen who then brought them to the attention of professional scientists. This illustrates the importance of engaging local communities in detecting non-indigenous species and monitoring their spread. © 2017 The Author(s). Journal compilation & 2017 REABIC.
