Exploring toxicological interactions in a changing sea: the case of the alkaloi...
Russo, Tania; Coppola, Francesca; Paris, Debora; De Marchi, Lucia; Meucci, Valentina; Motta, Andrea; Carbone, Marianna; Di Cosmo, AnnaThe bisindolic alkaloid caulerpin (CAU) is a bioactive compound isolated from green algae of the genus Caulerpa that are highly invasive in the Mediterranean Sea. On the other side, the purine alkaloid caffeine (CAF) is one of the most globally consumed psychoactive substances and a widespread anthropogenic water pollutant. Both compounds display a large panel of biological properties and are well known to accu...
An alien metabolite vs. a synthetic chemical hazard: an ecotoxicological compar...
Russo, Tania; Coppola, Francesca; Leite, Carla; Carbone, Marianna; Paris, Debora; Motta, Andrea; Di Cosmo, Anna; Soares, Amadeu M. V. M.; Mollo, ErnestoBioactive natural products from marine invasive species may dramatically impact native communities, while many synthetic pharmaceutical drugs are released into the marine environment and have long-lasting harmful effects on aquatic life. Sometimes, metabolites from alien species and synthetic compounds share similar mechanisms of action, suggesting comparable ecotoxicological impacts. This applies to the alkalo...
Calling activity and calls' temporal features inform about fish reproductive co...
Bolgan, Marta; Crucianelli, A.; Mylonas, C.C.; Henry, S.; Falguière, J.C.; Parmentier, E.; Mollo, ErnestoAlthough many fish species are vocal, the use of fish sounds for aquaculture management and wild population protection has not received much attention. In this study, sound production of three members of the Sciaenidae family was monitored before and during spawning in aquaculture facilities. The species examined include the meagre Argyrosomus regius, the shi dum Umbrina cirrosa and red drum Sciaenops ocellatus...
Effect of the algal alkaloid caulerpin on neuropeptide Y (NPY) expression in th...
Magliozzi, Laura; Maselli, Valeria; Almada, Frederico José Oliveira de; Di Cosmo, Anna; Mollo, Ernesto; Polese, GianlucaRecent studies have suggested that Mediterranean indigenous fish species are affected by bioactive metabolites coming from marine invasive species via food web interactions. In particular, both physiological and behavioural changes in the white sea bream Diplodus sargus were related to caulerpin (CAU), a bisindolic alkaloid particularly abundant in the invasive alga Caulerpa cylindracea, on which the fish activ...
H NMR spectroscopy and MVA to evaluate the effects of Caulerpin-Based diet on d...
Del Coco, Laura; Felline, Serena; Girelli, Chiara; Angilè, Federica; Magliozzi, Laura; Almada, Frederico José Oliveira de; D’Aniello, BiagioThe biological invasion of the green algae Caulerpa cylindracea represents a serious scientific and public issue in the Mediterranean Sea, essentially due to strong modifications both to habitat structure and native benthic communities. Although alterations in health status and changes in flesh quality of some marine species (dietary exposed to C. cylindracea) have been observed, no studies on cause-effect rela...
Cryptic effects of biological invasions: Reduction of the aggressive behaviour ...
Magliozzi, Laura; Almada, Frederico José Oliveira de; Robalo, Joana Isabel; Mollo, Ernesto; Polese, Gianluca; Gonçalves, Emanuel João; Felline, SerenaThe invasive green alga Caulerpa cylindracea has become an important component of the diet of the Mediterranean white seabream Diplodus sargus. As a consequence of this ªexotic dietº, the algal bisindolic alkaloid caulerpin accumulates in the fish tissues. Although the compound shows structural similarity to endogenous indolamines that modulate animal behaviour, the potential impact of caulerpin on fish behavio...
