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…
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…
Pattern formation and spatial correlation induced by the noise in two competing species
D. Valenti, A. Fiasconaro, B. Spagnolo
We analyze the spatio-temporal patterns of two competing species in the presence of two white noise sources: an additive noise acting on the interaction parameter and a multiplicat…
Enhancement of the escape time in metastable states with colored noise
A. Fiasconaro, D. Valenti, B. Spagnolo
We present a study of the escape time from a metastable state in the presence of colored noise, generated by Ornstein-Uhlenbeck process. We analyze the role of the correlated noise…
Noise Induced Phenomena in Lotka-Volterra Systems
B. Spagnolo, A. Fiasconaro, D. Valenti
We study the time evolution of two ecosystems in the presence of external noise and climatic periodical forcing by a generalized Lotka-Volterra (LV) model. In the first ecosystem,…
