Elucidating food webs in infralitoral rocky coastal habitats invaded by Caulerpa cylindracea (Sonder 1845)

Invasive species including Caulerpa cylindracea affect coastal benthic communities inducing structural changes. To assess effects in rocky ecosystems, food webs have been depicted based on stable isotopic data collected from invertebrates and fishes at invaded and non-invaded coastal areas. Isotopic values of invertebrates were slightly higher in invaded than non-invaded habitats of Lampedusa Island, however no significant differences were found. Invasive fish Siganus luridus and native Sparisoma cretense had similar isotopic signatures indicating similar food sources
