… We extend recent results obtained by Sardanyés et al. analyzing the effect of the mode of
replication together with different fitness landscapes on the mutational load and robustness of …

Background In recent years, research has been increasingly devoted to understanding the
complex human health-environment relationship. Nevertheless, many different …

Infectious disease control faces significant challenges including: how to therapeutically
target the highest-risk populations, circumvent behavioral barriers, and overcome pathogen …

Sudden changes in populations are ubiquitous in ecological systems, especially under
perturbations. The agents of global change may increase the frequency and severity of …

… a string, it was copied to site j with probability P i j = 1 1 + exp ( − Δ f i j / T ) that depends on
the fitness difference Δf ij = f i − f j between strings S i and S j (if site j is empty, f j = 0). T is the …

… i and the catalytically-assisted replication that species j provide to species i, respectively.
Since the architecture is cyclic, we shall impose j = n when i = 1 and j = i − 1 when i ≠ 1 . The …

In this article we provide homotopy solutions of a cancer nonlinear model describing the
dynamics of tumor cells in interaction with healthy and effector immune cells. We apply a semi-…

In this work we investigate the population dynamics of cooperative hunting extending the
McCann and Yodzis model for a three-species food chain system with a predator, a prey, and a …

Mounting theoretical and experimental evidence indicates that the success of molecular
replicators is strongly tied to the local nature of their interactions. Local dispersal in a given …

The tremendous evolutionary potential of RNA viruses allows them to thrive despite host
defense mechanisms and endows them with properties such as emergence, host switching, …
