Sea urchins rely on chemical senses to localize suitable food resources, therefore representing model species for chemosensory studies. In the present study, we investigated sensitivity of Mediterranean sea urchin Paracentrotus lividus blue-green alga Aphanizomenon flos-aquae, namely “Klamath”, and a few amino acids chosen from biochemical composition same algae. To this end, used “urchinogram”...

Abstract. We studied the Gioia Sannitica active normal fault (GF) along southern Matese (SMF) system in Apennines of Italy detail. The current activity and its potential to produce strong earthquakes have been underestimated so far are now defined here. Precise mapping GF trace on a 1:20 000 geological map point line data geometry, kinematics, slip rate faults forming SMF made available electro...
