	abstract = {<p>This study analyses the temporal and spatial changes in abundance and  distribution of the warm water species round sardinella (Sardinella  aurita) in the western Mediterranean over the last decades in relation  to sea water temperature. In the western Mediterranean basin  (1950-2003), a significant positive relationship was found between round  sardinella landings and temperature anomalies. Along a latitudinal  gradient off the Mediterranean Iberian coast (1989-2004), a gradual  increase in species abundance was observed from south to north, with a  certain time lag going northwards, associated with the increase in sea  water temperature. The abundance of round sardinella in the two warmest  and southernmost areas was positively and significantly correlated with  sea surface temperature registered during the start of gonad maturation  the previous year. In addition, the positive relationship established  between water temperature and abundanceof round sardinella in the  coldest and northernmost study area demonstrates that there is a  temperature limit for the distribution of this species in the western  Mediterranean. In addition, this study analyses round sardinella larvae  distribution and abundance in the summers of 2003 and 2004, and conducts  a comparison with the situation 20 years ago (summer 1983). Results  show a marked increase in larval abundance during the last decades and  the present appearance of larvae in the northernmost study areas, where  they did not occur 20 years ago. This indicates the successful  reproduction of round sardinella in the northern part of the  Mediterranean, where the species has expanded, confirming its  establishment in the area.</p>},
