Reconstructing Bioinvasion Dynamics Through Micropaleontologic Analysis Highlights the Role of Temperature Change as a Driver of Alien Foraminifera I…

2021

Invasive alien species threaten biodiversity and ecosystem structure and functioning, but incomplete assessments of their origins and temporal trends impair our ability to understand the relative importance of different factors driving invasion success. Continuous time-series are needed to assess invasion dynamics, but such data are usually difficult to obtain, especially in the case of small-sized taxa that may remain undetected for several decades. In this study, we show how micropaleontologic analysis of sedimentary cores coupled with radiometric dating can be used to date the first arrival and to reconstruct temporal trends of foraminiferal species, focusing on the alien Amphistegina lo…

A SMALL INVADER CONQUERS SICILY: AMPHISTEGINA LOBIFERA (FORAMINIFERA: AMPHISTEGINIDAE)

2018

The highly invasive Amphistegina lobifera (Larsen, 1976), a benthic foraminiferal species native to the Red Sea, has colonized the Eastern Mediterranean through the Suez Canal and altered the native community structure. More recently, it has been reported from Malta and the Pelagian Islands within the Sicily channel. Here, we report new records from the southern coasts of Sicily, where we found it abundant both in the soft-bottom sediment and as epiphyt on algae. The occurrence of A. lobifera in Pantelleria and Favignana islands represents the Mediterranean westernmost record of this non-indigenous species.

Abstract A detailed study of the marine sediments collected on the inner shelf of some of the selected areas of the central Mediterranean Sea has been carried out in order to verify the presence of exotic benthic foraminiferal species. Since 2000, the coastal marine environments of the Pelagian Islands and of Sicily (central Mediterranean) have been increasingly colonized by exotic species (i.e. fishes and algae) originating both from the Atlantic Ocean and the Red Sea. The studied areas (Pelagian Islands and SE Sicily) are located in the middle of the Mediterranean Sea. Therefore, they represent an ideal place to understand how exotic species, coming from different Oceans, may have coloniz…
