Oslo – On August 28 the scientific mission of a group of researchers from the University Sapienza of Rome came to an end. They monitored the biorhythm of Arctic animals to study the effects of different darkness/light patterns on their biological clock. The research was carried out at the base “Dirigibile Italy” in Ny-Alesund, Svalbard. The base is a multidisciplinary research station located in Norway’s Spitzbergen (Svalbard Islands), and is managed by the National Research Council. The mission, led by Vittorio Pasquali of the Neuroscience Division within the Psychology Department, sought to study Lepidulus arcticus (Branchiopora, Notostraca), a never analyzed before crustacean that could provide a model for the study of the expression of genes and biological rhythms.
