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 the Ionian Sea; first record of the redlip blenny, Ophioblennius atlanticus in the Ionian Sea; Slovenia: first record of the isopod Paranthura japonica in Slovenia; Greece: first record of the molluscs Eunaticina papilla, Plocamopherus ocellatus and the fish Cheilodipterus novemstriatus; first record of the ascidian Ecteinascidia turbinata in Kriti; the long-spined sea urchin Diadema setosum in the Ionian Sea; Turkey: first record of the sea spider Ammothea hilgendorfi; the stomatopod Cloridina cf. ichneumon; the fishes Pempheris rhomboidea from the Sea of Marmara and Paranthias furcifer from the Aegean Sea; Lebanon: new records of the fishes Arothron hispidus, Rachycentron canadum, Heniochus intermedius and Acanthurus monroviae; first record of Acanthostracion polygonius. The records of Cloridina cf. ichneumon from southern Turkey and the fish Acanthostracion polygonius from Lebanon, both being the first Mediterranean records, are noteworthy.

The composition of mesozooplankton and their space-time distribution in the Gulf of Vlore¨ (southern Albania, Mediterranean Sea) are described for the first time. Sampling was carried out during two oceanographic cruises (May 2007, January 2008) with two replicates at each of 17 stations at each time, making a total of 68 samples. The study aimed to describe the influence of confinement (defined as distance from the open sea) and anthropogenic impact (defined as vicinity to the east coast of the gulf) on zooplankton composition. A total of 198 taxa were recognised in the whole zooplankton assemblage, with only 136 taxa common to both periods and only two species present in all samples. Statistical analysis of data distinguished the Mezokanal area (the boundary between the gulf and the open sea) from three other areas inside the gulf. Differences were also found among the areas inside the gulf at increasing degree of confinement. Mesozooplankton varied more sharply with confinement than with anthropogenic impact and yielded moredetailed space partitioning of the gulf than microzooplankton, which had been used in a previous study

A public Aquarium was realized in the frame of the European Territorial Cooperation Programme, ETCP, Greece-Italy 2007-2013. Such a project (acronym APREH) started in 2011 with the University of Salento as Leader Partner, Province of Lecce and Municipality of Nardò as Italian partners, and University of Patra and Municipality of Kefallinia as Greek partners. The proposal of an Aquarium had the aim to promote the archaeological and natural submarine heritage along the coastline of the Salento Peninsula and of the Kefallinia island. The Italian partnership realized an Aquarium at Santa Maria al Bagno (Nardò, Lecce), restructuring an ancient building (Fig. 1) with services, a conference room, and 4 exhibition environments equipped with a total of 17 tanks of variable volume (25 – 2,500 litres), hosting a total of 100 species of marine organisms (Tab. 1, Fig. 2). Four tanks were equipped with reproductions of wrecks: a Junker 88 airplane, an Italian Cargo Ship, an English destroyer of the 2nd World War, and a Roman ship of the 2nd Century b.C. with its cargo of amphorae. The official opening was celebrated on 05 June 2015 (Fig. 3). The structure is the unique public Aquarium functioning in the Southern Italy apart from Naples; it has been open to visitors only during the 13 week ends of June-August, receiving more than 7,000 visitors mainly coming from Province of Lecce and the rest of Italy (Tab. 2). Also due to front end evaluation studies, a plan for the future functioning of the Aquarium is presented, taking into consideration its educative role, and its touristic attractiveness.
