Phase transition in random adaptive walks on correlated fitness landscapes
Su-Chan Park, Ivan G. Szendro, Johannes Neidhart +1
We study biological evolution on a random fitness landscape where correlations are introduced through a linear fitness gradient of strength . When selection is strong and mutati…
Multidimensional epistasis and the transitory advantage of sex
Stefan Nowak, Johannes Neidhart, Ivan G. Szendro +1
Identifying and quantifying the benefits of sex and recombination is a long standing problem in evolutionary theory. In particular, contradictory claims have been made about the ex…
Adaptation in tunably rugged fitness landscapes: The Rough Mount Fuji Model
Johannes Neidhart, Ivan G. Szendro, Joachim Krug
Much of the current theory of adaptation is based on Gillespie's mutational landscape model (MLM), which assumes that the fitness values of genotypes linked by single mutational st…
Exact Results for Amplitude Spectra of Fitness Landscapes
Johannes Neidhart, Ivan G. Szendro, Joachim Krug
Starting from fitness correlation functions, we calculate exact expressions for the amplitude spectra of fitness landscapes as defined by P.F. Stadler [J. Math. Chem. 20, 1 (1996)]…
Quantitative analyses of empirical fitness landscapes
Ivan G. Szendro, Martijn F. Schenk, Jasper Franke +2
The concept of a fitness landscape is a powerful metaphor that offers insight into various aspects of evolutionary processes and guidance for the study of evolution. Until recently…
Rare events in population genetics: Stochastic tunneling in a two-locus model with recombination
Alexander Altland, Andrej Fischer, Joachim Krug +1
We study the evolution of a population in a two-locus genotype space, in which the negative effects of two single mutations are overcompensated in a high fitness double mutant. We…
