Reliable approximation of separatrix manifolds in competition models with safety niches
Roberto Cavoretto, Alessandra De Rossi, Emma Perracchione +1
In dynamical systems saddle points partition the domain into basins of attractions of the remaining locally stable equilibria. This situation is rather common especially in populat…
Interplay of network dynamics and ties heterogeneity on spreading dynamics
Luca Ferreri, Paolo Bajardi, Mario Giacobini +2
The structure of a network dramatically affects the spreading phenomena unfolding upon it. The contact distribution of the nodes has long been recognized as the key ingredient in i…
Ecoepidemics with a nonlinear disease incidence
Ezio Venturino
We present two new models for interacting populations subject to a transmissible disease. The novelty lies in the assumption that herd behavior influences the disease incidence, ra…
Ecoepidemics with infected prey in herd defense: the harmless and toxic cases
Elena Cagliero, Ezio Venturino
We consider a predator-prey population model with prey gathering together for defense purposes. A transmissible unrecoverable disease affects the prey. We characterize the system b…
Chaos control via feeding switching in intraguild predation systems
Joydev Chattopadhyay, Nikhil Pal, Sudip Samanta +1
In the present paper we study a tri-trophic Lotka-Volterra food web model with omnivory and predator switching. We observe that if the intensity of predator switching increases the…
An ecoepidemic food chain with the disease at the intermediate trophic level
Lorenzo Bramante, Simone Maiolo, Ezio Venturino
We consider a three-level food chain in which an epidemics affects the intermediate population. Two models are presented, respectively either allowing for unlimited food supply for…
