“…The former is regularly seen in sites of the western Ligurian Sea and is apparently further expanding its range north-eastward; the latter seems already fully established [98]. D. cervinus is distributed in the eastern Atlantic coast, from the Bay of Biscay to the Cape Verde Islands, Madeira, and Canary Islands and from Angola to South Africa; it is also present in the warmer areas of the Mediterranean Sea [126]. Mycteroperca rubra is distributed along the eastern coast of the Atlantic Ocean, from Portugal to Angola and in the southern Mediterranean Sea.…”

Global warming is causing poleward expansion of species ranges. Temperate seas, in particular, are undergoing a process known as ‘tropicalisation’, i.e., the combination of sea-water warming and establishment of southern species. The Ligurian Sea is one of the coldest sectors of the Mediterranean and has thus been characterized by a dearth of warm-temperate species and a comparative abundance of cold-temperate species. This paper uses a time series of sea surface temperature (SST) and new records of thermophilic fish species to reconsider the biogeography of the Ligurian Sea. SST has risen by about 0.7 °C on average between 1948 and 2023, but two phases may be distinguished: a cool one (ended in the mid-1980s) and a warm one (still ongoing); the latter phase shows alternating periods of rapid warming and comparatively stationary temperature. The arrival of thermophilic species coincided with the periods of rapid warming; some of these species were established in the subsequent stationary periods. Heatwaves and climate-related diseases associated with the periods of rapid warming have caused mass mortalities of autochthonous species. Our knowledge on the biogeography of the Ligurian Sea was established during the cool phase; the present situation, however, calls for re-defining the chorological spectrum of the Ligurian Sea biota.

“…Among all potentially relevant abiotic factors, previous findings suggest seawater temperature playing a key role as a trigger of fish spawning, both in freshwater (King et al, 2016) and in marine species (Gill et al, 1996;Hereu et al, 2006;Winters & Wheeler, 1996). In the Mediterranean sea, temperature as a spawning cue has been already reported for Sparids: changing temperatures seem to trigger the onset of spawning for this family (Gonçalves, 2000;Mouine et al, 2011;Pajuelo et al, 2003Pajuelo et al, , 2006Pajuelo et al, , 2008. Here, we focus on a demersal fish of the Sparid family, the white sea bream Diplodus sargus (Linnaeus, 1758) as it is a relatively data-rich case study in the Mediterranean.…”

In bipartite life cycle fishes, spawning represents the onset of propagules dispersal, with eggs and larvae experiencing anisotropic transport and high mortality rates, before eventually metamorphosing and settling. Hence, early-life stages operate as bottlenecks for population demography by strongly constraining recruitment. Despite its significance, spawning is rarely explicitly considered in ecosystem management due to a lack of knowledge, for many species, about where and when spawning occurs. Previous evidences suggest that temperature is among the main drivers of spawning in Teleosts. Using the ecologically and economically relevant white seabream Diplodus sargus in the central Mediterranean Sea as a case study, we assess the abiotic factors that regulate the onset and duration of spawning and subsequent dispersal. Lagrangian backtracking simulations fed with early-life observations allow locating 11 spawning events, which are then associated to simulated temperatures ranging from 14.8 C to 20.6 C, in close agreement with previous estimates. Based on this range of suitable temperatures, we model the spatio-temporal variability of spawning success at broad-scale over 10 years (2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014) following the backtracking approach with hypothetical constant settlement areas. It highlights a prominent inter-annual variability in the Adriatic and Siculo-Tunisian strait driven by oceanographic processes. Moreover, a powerful clustering method uncovers relatively stable spawning areas in the Ligurian and Tyrrhenian seas with both early (January to Mid-February) and late (April to June) spawning peaks. Our methodology can be applied to other species and oceanic systems to investigate how oceanic processes impact spawning success, enabling the design of sound management strategies.

The complete nucleotide sequence of the mitochondrial (mt) genome of the demersal zebra seabream Diplodus cervinus (Lowe, 1838) was determined for the first time. The double stranded circular molecule is 16,559 base pairs (bp) in length and encodes for the typical 37 metazoan mitochondrial genes, and 2 non-coding regions (D-loop and L-origin). The gene arrangement of the D. cervinus mt genome follows the usual one for fishes. The nucleotide sequences of the mt protein coding and ribosomal genes of D. cervinus mt genome were aligned with orthologous sequences from representatives of the Sparidae family and phylogenetic relationships were inferred. Maximum likelihood analyses placed D. cervinus as a sister species of Diplodus sargus (Linnaeus, 1758).
