title: Presence of Gamma-Aminobutyric Acid (Gaba) in the Pedal Mucus of the Critically Endangered Species Patella ferruginea.
abstract: Patella ferruginea is a giant patellid limpet endemic to the Mediterranean Sea. It presently is in danger of extinction, and many have called for developing conservation measures including the mass production of spats for re-introduction projects. However, so far all attempts have been relatively unsuccessful. Previous work analyzing the effects of gamma-aminobutyric acid (GABA) on the recruitment of patellid limpets has shown that larvae respond to the presence of this signaling molecule. This response could explain the gregarious distribution typical of this species. In the present study, we demonstrated that GABA is naturally secreted by P. ferruginea in the pedal mucus. GABA is preferentially secreted during the summer, coinciding with the reproductive resting period of the species. Further research should aim to analyze the effects of GABA on larval development and metamorphosis in order to assess its potential use to improve conservation efforts.
