Cyclic Fluctuations, Climatic Changes and Role of Noise in Planktonic Foraminifera in the Mediterranean Sea
A. Caruso, M. E. Gargano, D. Valenti +2
The study of Planktonic Foraminifera abundances permits to obtain climatic curves on the basis of percentage ratio between tropical and temperate/polar forms. Climatic changes were…
Role of the Colored Noise in Spatio-Temporal Behavior of Two Competing Species
D. Valenti, A. Fiasconaro, B. Spagnolo
We study the spatial distributions of two randomly interacting species, in the presence of an external multiplicative colored noise. The dynamics of the ecosystem is described by a…
Generalized Wiener Process and Kolmogorov's Equation for Diffusion induced by Non-Gaussian Noise Source
Alexander Dubkov, Bernardo Spagnol
We show that the increments of generalized Wiener process, useful to describe non-Gaussian white noise sources, have the properties of infinitely divisible random processes. Using…
Noise Enhanced Stability
Bernardo Spagnolo, Nikolay V. Agudov, Alexander A. Dubkov
The noise can stabilize a fluctuating or a periodically driven metastable state in such a way that the system remains in this state for a longer time than in the absence of white n…
Exact Results for Spectra of Overdamped Brownian Motion in Fixed and Randomly Switching Potentials
A. A. Dubkov, V. N. Ganin, B. Spagnolo
The exact formulae for spectra of equilibrium diffusion in a fixed bistable piecewise linear potential and in a randomly flipping monostable potential are derived. Our results are…
Noise in ecosystems: a short review
B. Spagnolo, D. Valenti, A. Fiasconaro
Noise, through its interaction with the nonlinearity of the living systems, can give rise to counter-intuitive phenomena such as stochastic resonance, noise-delayed extinction, tem…
