“…Furthermore, the record months fit well with the general trend observed in the Mediterranean (Dulčić et al, 2005;Psomadakis et al, 2006;Francour et al, 2010), whereas the capture of one individual at each site confirms the belief that the species is solitary (Palmer, 1986;Dulčić et al, 2005). Francour et al (2010) remarked that sightings of Lampris guttatus have clearly increased in the last years, especially after 2008, due to the current warming of the Mediterranean Sea, which is acting as a catchment basin for southern or thermophilic species (Çinar et al, 2011;Lefkaditou et al, 2011). Opah cannot thermoregulate itself (Polovina et al, 2008) and its spread process appears to be favoured by the present increase in sea temperature.…”

This paper presents records extending or confirming the distribution of Mediterranean species. Three alien algae are included, namely Codium taylorii reported for the first time from the Aegean and Turkey (Izmir Gulf), Caulerpa racemosa var. cylindracea (Karpathos and Chalki Isl., Aegean Sea) and Ganonema farinosum (Karpathos Isl., Aegean Sea). As far as animals are concerned, Litarachna divergens (Acari: Hydrachnidia) was recorded (Side, Eastern Mediterranean) and represents a new amendment at genus level for Turkish fauna. Other invertebrates include alien species such as the crabs Dyspanopeus sayi (Lago Fusaro, SW Italy), Percnon gibbesi (Larnaca, Cyprus; Karpathos and Chalki Isl., Aegean Sea) and Callinectes sapidus (Voda estuary, NW Greece), the nudibranch Aplysia dactylomela (Boka Kotorska Bay, Montenegro), the gastropod Conomurex persicus (Karpathos and Chalki Isl., Aegean Sea) and the bryozoan Electra tenella (Livorno harbour and Messina Straits area). The alien fish Siganus luridus, Siganus rivulatus, Fistularia commersonii, Sphyraena chrysotaenia and Sargocentron rubrum are also reported from the islands of Karpathos and Chalki, and Pteragogus pelycus from Heraklion Bay, Crete. In addition, new localities for four rare Mediterranean inhabitants are given: the cephalopod Thysanoteuthis rhombus (NW Sardinia) and the fish: Lampris guttatus (Calabria, S Italy), Petromyzon marinus (Gokova Bay) and Remora australis (Saronikos Gulf), while the opisthobranch gastropod Cerberilla bernadettae is reported for the first time from the E Mediterranean (Cyprus). Finally, three species of the Aegean ascidiofauna are recorded for the first time: Lissoclinum perforatum, Ciona roulei and Ecteinascidia turbinata. Furthermore, it was established that Phallusia nigra has extended its distributional range to the north of the Aegean Sea.

“…Overall, our results suggest that sea warming (0.032 °C year –1 for the upper 85 m of the water column on the northern Catalan shelf from 1974 to 2005; Vargas‐Yáñez et al ., ) is partly responsible for the observed changes in the spatio‐temporal abundance of warm‐water species. Other studies carried out in the Mediterranean support the theory that sea warming may be responsible for the northward spread and increasing abundance of thermophilic species such as Pomatomus saltatrix (Sabatés et al ., ), Sardinella aurita (Sabatés et al ., ), Lampris guttatus (Francour et al ., ) or Sphyraena viridensis (Villegas‐Hernández et al ., ). Nevertheless, the responsiveness of species to climate change involves interactions with various biotic and abiotic factors (Bates et al ., ) and therefore other issues, such as the establishment of marine reserves and the consequent reduction or prohibition of fishing in such areas, may have encouraged an increase in the populations of thermophilic fish species such as Diplodus cervinus cervinus and Epinephelus spp.…”

Predicting the impact of climate change on marine ecosystems or how fish and other species are adapting to rising sea temperatures is still subject to much uncertainty, despite considerable progress in recent years. In this study we assess whether our understanding of the impact of sea warming on marine fish can be enhanced with an interdisciplinary approach that collates data from fisheries, fishermen and scientific research. By doing this, we aim to shed light on the major changes in the abundance and diversity of warm and cold water fish in recent decades in relation to sea warming. Location: This study was conducted in the north-western Mediterranean, where the impacts of global warming are particularly critical because range shifts are physically constrained. Methods: We collected and combined statistical data from fisheries, the traditional ecological knowledge of fishermen (TEK), reproductive data (histological gonad analyses and ichthyoplankton surveys) and extensive research into the relevant literature (including systematic catalogues and museum collections and their databases). Results: We have found that changes in the abundance of fish have followed a particular spatio-temporal sequence, with three different phases of colonization in the case of warm-water species (occasional occurrence, common presence and establishment), and three phases of regression (abundance reduction, range contraction and disappearance from the catch) in the case of cold-water species. Main conclusions: Overall, the results show that this multidisciplinary approach, combining qualitative and quantitative information from different sources, provides new insight into the observed changes in fish diversity and abundance in relation to climate changeThis study was financed by the Abertis Foundation (http://www.fundacioabertis.org/).

“…data). Also, more than 70% of Lampris guttatus specimens reported by Francour et al (2010) within the western Mediterranean (the oldest record before 1807) have been observed since 1997. The increase in records of species coming from the Atlantic could be attributed to: (i) a recent increase in water flux from the Atlantic to the Mediterranean through the Straits of Gibraltar; and (ii) changes in hydroclimatic conditions, such as the warming of the Mediterranean Sea, which would favour the spreading of species with subtropical and tropical affinities (e.g.…”
