Influence of Mediterranean Sea Temperature Increase on Gaeta Gulf (Tyrrhenian Sea) Biodiversity

摘要: In this study, temperature variations and invasion on marine fauna are investigated to ascertain their relationship in the Mediterranean at Gaeta Gulf (Tyrrhenian Sea). Sea temperatures were collected from 1986 2009, only period which AVHRR sensor installed NOAA satellite was available. Changes sea surface using GIS software estimated. Research species carried out barcoding technique. Nine organisms of one Anthozoa Malacostraca eight belonging Actinopterygii Class barcoded 2005 2019 four these detected as non-indigenous species. The first sightings related Fistularia commersonii, Sphoeroides pachygaster identified since 2009 well reported our previous publication. They have penetrated Indian Ocean (through Suez Canal) Atlantic (Strait Gibraltar) respectively still sporadic. These bioinvasions linked for time water heating, increased by about 0.4 °C between 1989–1999 1999–2009. addition, there other identifications, such Arothron diadematus Canal, Percnon gibbesi Strait Gibraltar; thermophilus indigenous Pomadasys incisus Astroides calycularis sporadic autochthonous Sudis hyalina, Tetragonurus cuvieri, Trachipterus trachipterus, Remora osteochir. Non-native invasions could lead radical sudden upheavals ecosystem therefore require constant alert change.
