    "abstract": "The study of Planktonic Foraminifera abundances permits to obtain climatic\ncurves on the basis of percentage ratio between tropical and temperate/polar\nforms. Climatic changes were controlled by several phenomena as: (i)\nMilankovitch\u0027s cycles, produced by variations of astronomical parameters such\nas precession, obliquity and eccentricity; (ii) continental geodynamic\nevolution and orogenic belt; (iii) variations of atmospheric and oceanic\ncurrents; (iv) volcanic eruptions; (v) meteor impacts. But while astronomical\nparameters have a quasi-regular periodicity, the other phenomena can be\nconsidered as \"noise signal\" in natural systems. The interplay between cyclical\nastronomical variations, the \"noise signal\" and the intrinsic nonlinearity of\nthe ecologic system produces strong glacial or interglacial period according to\nthe stochastic resonance phenomenon.",
