“…Salaria pavo is a fish with high thermal preferences and laboratory studies showed that development of the embryos is arrested at temperatures of 15°C or lower (Westernhagen, 1983). Hayes et al (2005) estimated that western Mediterranean sea surface temperatures in the last glacial maximum ranged from about 9°C in winter to 13°C in summer. These values mean that temperatures suitable for the reproduction of S. pavo were likely absent, in much of the Mediterranean.…”

a b s t r a c tIn this paper, the phylogenetic relationships of the marine blenny Salaria pavo and the freshwater S. fluviatilis and S. economidisi were analyzed using four molecular markers: the mitochondrial 12S rRNA, 16S rRNA, and the control region and the nuclear first intron of the S7 ribosomal protein. The monophyly of Salaria is supported, as well as that of S. pavo and that of all the freshwater members of Salaria. Thus, the present results support a single origin for all freshwater Mediterranean blenniids. Our results reject the placement of the species of Salaria in the genus Lipophrys as proposed in previous studies. Using a molecular clock calibrated with trans-Isthmian geminate blenniid species, the split between the ancestor of the freshwater lineage and the ancestor of S. pavo is tentatively placed in the Middle Miocene (well before the Messinian). The marine S. pavo displays a very low level of intraspecific sequence divergence consistent with a Pleistocene bottleneck. S. fluviatilis is a paraphyletic entity with S. economidisi nested within it. A Moroccan population of S. fluviatilis is more divergent than S. economidisi, both in nuclear and mitochondrial genes. Fish from Israel together with some Turkish samples represent the second oldest split. It is argued that these populations may represent cryptic species. Thus, further studies on the taxonomy of these freshwater blennies are urgently needed.

“…However, seasonal estimates of Last Glacial Maximum (LGM) SST have been made throughout the Mediterranean Sea using (Fairbanks et al, 2005) and corrected for the Mediterranean Sea reservoir age of 390 year (Siani et al, 2000(Siani et al, , 2001, but may be up to 1500 years too old due to incorporation of dead carbon from limestone rocks. foraminiferal assemblages (Hayes et al, 2005). Comparison of these estimates with the reconstructed SST from a Patella shell dated at 19 kyrs BP (shown in Figs.…”

Editor: P. DeMenocalKeywords: mollusc seasonality Gibraltar palaeoclimate oxygen isotopesThe seasonal cycle is a fundamental aspect of climate, with a significant influence on mean climate and on human societies. Assessing seasonality in different climate states is therefore important but, outside the tropics, very few palaeoclimate records with seasonal resolution exist and there are currently no glacial-age seasonal-resolution sea-surface-temperature (SST) records at mid to high latitudes. Here we show that both Mg/Ca and oxygen isotope (δ 18 O) ratios in modern limpet (Patella) shells record the seasonal range of SST in the western Mediterranean -a region particularly susceptible to seasonal change. Analysis of a suite of fossil limpet shells from Gibraltar shows that SST seasonality was greater during the last glacial by~2°C as a result of greater winter cooling. These extra-tropical seasonal-resolution SST records for the last glacial suggest that the presence of large ice-sheets in the northern hemisphere enhances winter cooling. This result also indicates that seasonality in the Mediterranean is not well-represented in most palaeoclimate models, which typically show little change in seasonal amplitude, and provides a new test for the accuracy of climate models.

“…Emeis et al (2000) documented in a study about the SST of the Mediterranean Sea that the SST was varying between 12.3 ºC and 24.4 ºC in the sub-basins over the last 16,000 years. Also, Hayes et al (2005) analyzed the annual average of the SST in the last glacier period, and pointed out a variation in the SST from 9 ºC to 19 ºC in the Mediterranean sub-basins. Marullo et al (2007) investigated the correlation of remote sensed SST (i.e., AVHRR Pathfinder version 5.0) and measured SST in the Mediterranean Sea for a 21-year time period.…”

Abstract. The warming in the inner seas could not be more important and time is certainly running out for it. This study highlights important results about the detectable and predictable warming of the sea surface temperature (SST) in the Mediterranean Sea. The featured analysis of the SST is based on the remote sensed and corrected SST data for the period 1986-2015, and predicted data by using a linear black box model for period -2100 . The 30-year (1986 SST analysis shows an increase of about 0.4 ºC per decade. The most fluctuation in the monthly SST was generally detected at the beginning of the summer period. In the last 30 years of this century (2071-2100), the relative increase in average SST is predicted to be about 5.8 ºC in the Mediterranean Sea by the model. The analysis and prediction of the recent studies showed a perceptible warming in the sea surface during the last decades, and the warming will also continue to increase under the present environmental condition.
