Resumen: El hallazgo de dos poblaciones muy densas de Cerithium scabridum confirma el estatus invasivo de esta especie en las costas mediterráneas de la Península Ibérica donde, hasta el momento, solo se habían hallado unos pocos ejemplares. Abstract: The discovery of two quite dense populations of Cerithium scabridum confirms the invasive status o...

A new species of the amphipod genus Pontocrates (Boeck 1871), family Oedicerotidae, is described from Cyprus in the south-eastern Mediterranean Sea. It is a sister taxon to Pontocrates moorei (Myers & Ashelby 2022), currently recorded solely from the British Isles. It is the third species of Pontocrates now known to occur in the Mediterranean Sea.
In May 2023, one pair of Common Shelduck Tadorna tadorna successfully nested at the coastal wetland of Marchica (Sebkha Bou Areg), a Ramsar site on the Mediterranean coast of Morocco. The Common Shelduck is not currently in the list of breeding birds of Morocco and this observation represents the first proven breeding case for this species in Moroc...
In this new contribution to knowledge of scleractinians from the Pliocene of Siena, some species belonging to genera common in the Pliocene (Caryophyllia, Flabellum, Balanophyllia, Cladopsammia and Dendrophyllia) are described. One species is attributed, albeit dubiously, to a genus not hitherto reported from the Pliocene of the Mediterranean (Anom...
An adult of Acanthurus xanthopterus Valenciennes, 1835 was caught in the waters off Alexandria, Egypt, in August 2021, through spearfishing. This finding documents the first occurrence of the species in the Mediterranean basin. Description of the specimen, morphometric measurements and meristic characters are given. The yellowfin surgeonfish is wid...
In October 2020, a single specimen of the daggertooth pike conger, Muraenesox cinereus (Forsskål, 1775), was caught by longline at a depth of 120 m, from the Mediterranean coast of Turkey. This species has been recorded from the Mediterranean for the second time after approximately four decades. This new finding shows that the distribution of the s...

... The opening and subsequent enlargement of the Suez Canal in 1869 also allowed several estuarine gastropods of Indo-Pacific origin (the so-called Lessepsian migrants) to colonise the Mediterranean Sea (Nunes et al. 2014), and spread over transitional waters of the Iberian coast. For instance, such is the case of the molluscs Fulvia fragilis, Bursatella leachii, Pinctada radiata and Cerithium scabridum (López-Soriano et al. 2020). Moreover, anthropogenic modifications of Iberian estuaries may facilitate the establishment of those NIS that are more environmentally tolerant (González-Ortegón and Moreno-Andrés 2021). ...
Aquatic ecosystems are particularly vulnerable to the introduction of non-indigenous species (NIS), leading to multi-faceted ecological, economic and health impacts worldwide. The Iberian Peninsula comprises an exceptionally biodiverse Mediterranean region with a high number of threatened and endemic aquatic species, most of them strongly impacted by biological invasions. Following a structured approach that combines a systematic review of available information and expert opinion, we provide a comprehensive and updated multi-taxa inventory of aquatic NIS (fungi, macroalgae, vascular plants, invertebrates and vertebrates) in Iberian inland waters. Moreover, we assess overall patterns in the establishment status, introduction pathways, native range and temporal introduction trends of listed NIS. In addition, we discuss the legal coverage provided by both national (Spanish and Portuguese) and European NIS regulations. We inventoried 326 aquatic NIS in Iberian inland waters, including 215 established, 96 with uncertain establishment status and 15 cryptogenic taxa. Invertebrates (54.6%) and vertebrates (24.5%) were the groups with the highest number of NIS, with Arthropoda, Mollusca, and Chordata being the most represented phyla. Recorded NIS originated from diverse geographic regions, with North and South America being
the most frequent. Vertebrates and vascular plants were mostly introduced through intentional pathways (i.e. release and escape), whereas invertebrates and macroalgae arrived mostly through unintentional ways (i.e. contaminant or stowaway). Most of the recorded NIS were introduced in Iberian inland waters over
the second half of the 20th century, with a high number of NIS introductions being reported in the 2000s. While only 8% of the recorded NIS appear in the European Union list of Invasive Alien Species of Union concern, around 25% are listed in the Spanish and Portuguese NIS regulations. This study provides the most updated checklist of Iberian aquatic NIS, meeting the requirements set by the EU regulation and providing a baseline for the evaluation of its application. We point out the need for coordinated transnational strategies to properly tackle aquatic invasions across borders of the EU members.
