Marrec L, Bank C, Bertrand T
Ecol Evol
. 2023 Aug;
13(8):e10295.
PMID: 37529585
Population growth is a fundamental process in ecology and evolution. The population size dynamics during growth are often described by deterministic equations derived from kinetic models. Here, we simulate several...

Marrec L, Bank C
Proc Biol Sci
. 2023 May;
290(1999):20230770.
PMID: 37253425
No environment is constant over time, and environmental fluctuations impact the outcome of evolutionary dynamics. Survival of a population not adapted to some environmental conditions is threatened unless, for example,...

Marrec L, Lamberti I, Bitbol A
Phys Rev Lett
. 2021 Dec;
127(21):218102.
PMID: 34860074
A key question in evolution is how likely a mutant is to take over. This depends on natural selection and on stochastic fluctuations. Population spatial structure can impact mutant fixation...

Genetics
. 2020 Aug;
216(2):573-583.
PMID: 32855198
We investigate the evolutionary rescue of a microbial population in a gradually deteriorating environment, through a combination of analytical calculations and stochastic simulations. We consider a population destined for extinction...

PLoS Comput Biol
. 2020 Apr;
16(4):e1007798.
PMID: 32275712
The evolution of antimicrobial resistance can be strongly affected by variations of antimicrobial concentration. Here, we study the impact of periodic alternations of absence and presence of antimicrobial on resistance...

Bansept F, Marrec L, Bitbol A, Loverdo C
Evolution
. 2019 Apr;
73(6):1077-1088.
PMID: 30957218
The body is home to a diverse microbiota, mainly in the gut. Resistant bacteria are selected by antibiotic treatments, and once resistance becomes widespread in a population of hosts, antibiotics...

Marrec L, Bitbol A
J Theor Biol
. 2018 Sep;
457:190-198.
PMID: 30172688
The evolution of antimicrobial resistance generally occurs in an environment where antimicrobial concentration is variable, which has dramatic consequences on the microorganisms' fitness landscape, and thus on the evolution of...
