Spatio-temporal behaviour of the deep chlorophyll maximum in Mediterranean Sea: Development of a stochastic model for picophytoplankton dynamics
G. Denaro, D. Valenti, A. La Cognata +7
In this paper, by using a stochastic reaction-diffusion-taxis model, we analyze the picophytoplankton dynamics in the basin of the Mediterranean Sea, characterized by poorly mixed…
Dynamics of a FitzHugh-Nagumo system subjected to autocorrelated noise
D. Valenti, G. Augello, B. Spagnolo
We analyze the dynamics of the FitzHugh-Nagumo (FHN) model in the presence of colored noise and a periodic signal. Two cases are considered: (i) the dynamics of the membrane potent…
Evidence of stochastic resonance in the mating behavior of Nezara viridula (L.)
S. Spezia, L. Curcio, A. Fiasconaro +6
We investigate the role of the noise in the mating behavior between individuals of Nezara viridula (L.), by analyzing the temporal and spectral features of the non-pulsed type fema…
Monitoring noise-resonant effects in cancer growth influenced by external fluctuations and periodic treatment
Alessandro Fiasconaro, Anna Ochab-Marcinek, Bernardo Spagnolo +1
In the paper we investigate a mathematical model describing the growth of tumor in the presence of immune response of a host organism. The dynamics of tumor and immune cells is bas…
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…
