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…

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…
