Cell expansion-division under resource limitation: a novel framework for modeling fruit growth dynamics

The paper presents a mathematical framework to model fruit growth by integrating cellular dynamics and resource allocation, linking genetic and environmental factors to fruit traits.

Spatial heterogeneity alters the trade-off betweengrowth and dispersal during a range expansion

The paper shows spatial heterogeneity shifts the growth-dispersal trade-off from R-strategies to D-strategies during range expansion in a fragmented environment.

Dynamics of Aedes albopictus invasion. Insights from a spatio-temporal model

The paper develops a spatio-temporal model to predict the expansion of Aedes albopictus and its future distribution under different climate scenarios.

The emergence of a birth-dependent mutation rate in asexuals: causes and consequences

This study shows that in asexual populations, a positive correlation between birth rate and mutation rate emerges naturally, leading to new evolutionary dynamics and trade-offs.

Emerging strains of watermelon mosaic virus in Southeastern France: model-based estimation of the dates and places of introduction

The paper estimates the dates and places of introduction of emerging watermelon mosaic virus strains using a model-based approach applied to spatio-temporal genetic variant data.

Dynamics of adaptation in an anisotropic phenotype-fitness landscape

This paper analyzes adaptation dynamics in an anisotropic phenotype-fitness landscape and shows that mean fitness trajectories may exhibit plateaus before converging, fitting empirical data from E. coli evolution experiments.

Population persistence under high mutation rate: from evolutionary rescue to lethal mutagenesis

The paper studies how high mutation rates affect population persistence, showing that moderate increases can aid evolutionary rescue while larger increases lead to extinction via lethal mutagenesis.

When sinks become sources: adaptive colonization in asexuals

This study develops a framework to analyze the establishment of asexual populations in a sink habitat, showing how mutation and immigration rates influence success and timing.

Dynamics of fitness distributions in the presence of a phenotypic optimum: an integro-differential approach

The paper develops an integro-differential model to study fitness distribution dynamics under mutation and selection, showing phase transitions and validating results with simulations.

When higher carrying capacities lead to faster propagation

The paper investigates the relationship between carrying capacity and propagation speed in population expansion using mathematical models and experiments, finding a positive correlation under certain conditions.

The non-stationary dynamics of fitness distributions: asexual model with epistasis and standing variation.

This paper develops a deterministic approximation framework to model asexual fitness dynamics, capturing both transient and stationary behaviors across mutation rates and epistasis models.
