Impact of population size on early adaptation in rugged fitness landscapes

Anne-Florence Raphaëlle Bitbol, Richard Marie Servajean

Owing to stochastic fluctuations arising from finite population size, known as genetic drift, the ability of a population to explore a rugged fitness landscape depends on its size. In the weak mutation regime, while the mean steady-state fitness increases ...

Environmental care and morality: An economic model with heterogeneous agents

Boris Thurm, Charles Chadi Ayoubi

Some individuals voluntarily engage in costly pro-environmental actions although their efforts have limited direct benefits. This paper proposes a novel economic model with heterogeneous agents explaining why. Each agent has a homo moralis type of preferen ...

Limits on amplifiers of natural selection under death-Birth updating

Andreas Pavlogiannis

The fixation probability of a single mutant invading a population of residents is among the most widely-studied quantities in evolutionary dynamics. Amplifiers of natural selection are population structures that increase the fixation probability of advanta ...

Active Site-Induced Evolutionary Constraints Follow Fold Polarity Principles in Soluble Globular Enzymes

Matteo Dal Peraro, Luciano Andres Abriata, Alexander Mayorov

A recent analysis of evolutionary rates in >500 globular soluble enzymes revealed pervasive conservation gradients toward catalytic residues. By looking at amino acid preference profiles rather than evolutionary rates in the same data set, we quantified th ...

Eco-Evolutionary Dynamics Linked to Horizontal Gene Transfer in Vibrios

Melanie Blokesch, Frédérique Marie Jeanne Le Roux

Vibrio is a genus of ubiquitous heterotrophic bacteria found in aquatic environments. Although they are a small percentage of the bacteria in these environments, vibrios can predominate during blooms. Vibrios also play important roles in the degradation of ...

Convergent genomic signatures of domestication in sheep and goats

Stéphane Joost, Pierre Taberlet

The evolutionary basis of domestication has been a longstanding question and its genetic architecture is becoming more tractable as more domestic species become genome-enabled. Before becoming established worldwide, sheep and goats were domesticated in the ...

Computational and Statistical analyses of Molecular Evolution and Demography using Large-scale Sequencing Data

Adamantia Kapopoulou

Evolution can be described as the change of allele frequencies over time. Four forces - mutation, migration, genetic drift, and selection, drive this change. The aim of my thesis was to accurately estimate and differentiate the parameters governing each of ...

A heterogeneous evolutionary stable population under assortative matching: Exploring the diversity of preferences

Boris Thurm, Charles Chadi Ayoubi

Recent studies have shown that a population acting not only upon self-interest but also exhibiting some morality preference has an evolutionary advantage. Specifically, in the setting of a symmetric fitness game, a resident population is evolutionary stabl ...

Inference of genealogies with geolocalised genetic data

Natural populations present an abundant genetic variability. Like mutation or natural se- lection, dierent processes are at stake to generate this variability. Population genetics is a topic that emerged in the late 40's, thanks mainly to the biologists Fi ...

Antiviral drug resistance as an adaptive process

Kristen Kay Irwin, Jeffrey David Jensen

Antiviral drug resistance is a matter of great clinical importance that, historically, has been investigated mostly from a virological perspective. Although the proximate mechanisms of resistance can be readily uncovered using these methods, larger evoluti ...
