Polymerase-mediated quasispecies dynamics: bifurcations, complementation, and robustness of τ-tipping
Edward A. Turner, Francisco Crespo, Nolbert Morales +2
Quasispecies theory describes how mutation and selection shape highly variable RNA virus populations, but most models explicitly consider neither RNA-dependent RNA polymerases nor…
Global dynamics and regime shifts in a resource-consumer model with facilitation and habitat loss
Teodoro Mayayo, Josep Sardanyés, Joan Torregrosa
Modelling how populations respond to habitat loss is crucial for understanding ecosystem stability, especially when positive interactions among resource species, such as plant-plan…
Lag-Induced Critical Transitions to Extinction in Replicating Systems
Edward A. Turner, Francisco Crespo, Joan Gimeno +3
Replicating systems sustained by error-prone enzymatic amplification can undergo critical transitions between persistence and extinction. In RNA viruses, such transitions are class…
Multiscale feedback drives viral evolution and epidemic dynamics
Juan C. Muñoz-Sánchez, J. Tomás Lázaro, Josep Sardanyés +1
We introduce a minimal multiscale framework that links within-host virus dynamics to population-level SIRS epidemiology through explicit, bidirectional coupling. At the microscopic…
